Organization, Consolidation and Presentation of Financial Statements [Abstract] | |
Description of the business | Description of the business Paratek Pharmaceuticals, Inc., or the Company or Paratek, is a Delaware corporation with its corporate office in Boston, Massachusetts and an office in King of Prussia, Pennsylvania. The Company is a commercial-stage biopharmaceutical company focused on the development and commercialization of novel life-saving therapies for life-threatening diseases or other public health threats for civilian, government and military use. The Company’s United States, or U.S., Food and Drug Administration, or FDA, approved commercial product, NUZYRA® (omadacycline), is a once-daily oral and intravenous antibiotic for the treatment of adult patients with community-acquired bacterial pneumonia, or CABP, and acute skin and skin structure infections, or ABSSSI, caused by susceptible pathogens. The Company retains worldwide commercial rights to omadacycline, with the exception in the People’s Republic of China, Hong Kong, Macau and Taiwan, where it has entered into a collaboration agreement with Zai Lab (Shanghai) Co., Ltd., or Zai. The National Medical Products Administration, or NMPA, of China approved NUZYRA for the treatment of adult patients with CABP and ABSSSI in December 2021. China’s National Healthcare Security Administration added the intravenous formulation of NUZYRA to the country's National Reimbursement Drug List for the treatment of CABP and ABSSSI in January 2023, resulting in millions of patients gaining access to this once daily broad-spectrum antibiotic. SEYSARA® (sarecycline) is an FDA-approved product which the Company has exclusively licensed in the U.S. and the People’s Republic of China, Hong Kong and Macau, and Taiwan, certain rights to Almirall, LLC, or Almirall. SEYSARA is currently being marketed by Almirall in the U.S. as a once-daily oral therapy for the treatment of moderate to severe acne vulgaris. With respect to the Company’s technology as it relates to sarecycline, the Company retains development and commercialization rights in all countries other than the U.S. and the greater China region, and in February 2020, the Company exclusively licensed from Almirall certain technology owned or in-licensed by Almirall or its affiliates that is necessary or useful to develop or commercialize sarecycline outside of the U.S. Almirall plans to develop sarecycline for acne in China, with a submission to the NMPA expected in 2023, according to Almirall. On June 6, 2023, the Company announced it had entered into a definitive agreement, or the Merger Agreement, to be acquired by Gurnet Point Capital, or Gurnet Point, and Novo Holdings A/S, or Novo Holdings, in a transaction valued at approximately $462.0 million, including the assumption of debt and assuming full payment of a Contingent Value Right, or CVR. This transaction is referred to herein as the Merger. Debt financing of $175.0 million for the Merger will be provided by funds managed by Oaktree Capital Management, L.P. Under the terms of the Merger Agreement, Gurnet Point, a leading healthcare investment firm, and Novo Holdings, a holding and investment company responsible for managing the assets and wealth of the Novo Nordisk Foundation, will acquire all outstanding shares of Paratek for $2.15 per share in cash, plus a CVR of $0.85 per share payable upon the achievement of $320.0 million in U.S. NUZYRA net sales (excluding certain permitted deductions, payments under Paratek's contract with ASPR-BARDA, certain government payments and certain royalty revenue) in any calendar year ending on or prior to December 31, 2026. The transaction, which our Board of Directors has unanimously approved, is subject to customary closing conditions, including approval by our stockholders and receipt of regulatory approvals. Following completion, Paratek will become a private company and will no longer be subject to the reporting requirements of the Securities Exchange Act of 1934, as amended, nor be traded on Nasdaq Global Market. Between July 11, 2023 and July 27, 2023, the Company received eight demand letters, or the Demand Letters, each from a purported stockholder of the Company alleging to have identified purportedly materially misleading and incomplete statements in the preliminary proxy statement filed by the Company on June 30, 2023. Certain of the Demand Letters also purport to raise issues with aspects of the process that led to the Merger. Certain of those Demand Letters were served pursuant to Section 220 of the Delaware General Corporation Law and seek books and records of the Company related to the Merger. The Company believes the allegations asserted in the Demand Letters are without merit. Additional demand letters or lawsuits relating to the Merger may also be received and/or filed in the future. The Company has incurred significant losses since inception in 1996. The Company has generated an accumulated deficit of $965.1 million through June 30, 2023 and may require substantial additional funding in connection with the Company’s continuing operations to support clinical development and commercialization activities associated with NUZYRA. As of June 30, 2023, the Company had cash and cash equivalents of $42.7 million on hand. The Company's current level of cash and cash equivalents may not be sufficient to fund operations for the next twelve months following the issuance of these financial statements. As a result, substantial doubt is deemed to exist regarding the Company’s ability to continue as a going concern for a period of one year from the issuance of these financial statements. If the transaction with Gurnet Point and Novo Holdings is not consummated, the Company expects to finance future cash needs primarily through a combination of product sales, royalties, public or private equity offerings, debt or other structured financings, strategic partnership opportunities, government funding and active management of cash and expenses through operational efficiencies. With the Company’s convertible notes coming due on May 1, 2024, the Company believes it will need to successfully execute one or more financing transactions prior to that date or otherwise risk bankruptcy. The Company anticipates that any such financing transactions, if they could be completed, would likely be substantially dilutive to current Company stockholders. Further, to fund our future cash needs in absence of the transaction with Gurnet Point and Novo Holdings, the Company’s plans would require it to significantly reduce its workforce, including substantial reductions among the sales force, without materially negatively impacting the Company’s ability to generate sales of NUZYRA or to otherwise successfully operate its business. The Company also anticipates that an amendment to the convertible notes would likely require the grant of a security interest, thereby restricting the Company’s ability to raise debt financing in the future. There can be no assurance that the Company would be successful in securing additional funds on acceptable terms, or at all. If additional funds are not available, the Company may be forced to cease operations, significantly reduce operating expenses or delay, curtail, or eliminate one or more of its development programs or its business operations. The accompanying consolidated financial statements have been prepared on a going concern basis, which contemplates the realization of assets and satisfaction of liabilities in the ordinary course of business. The consolidated financial statements do not include any adjustments relating to the recoverability and classification of recorded asset amounts or the amounts and classification of liabilities that might result from the outcome of this uncertainty. |

Accounting Policies [Abstract] | |
Summary of Significant Accounting Policies and Basis of Presentation | Summary of Significant Accounting Policies and Basis of Presentation Basis of Presentation The accompanying condensed consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles, or U.S. GAAP, as found in the Accounting Standards Codification, or ASC, and Accounting Standards Updates, or ASU, of the Financial Accounting Standards Board, or FASB, and pursuant to the rules and regulations of the SEC. The accompanying condensed consolidated financial statements are unaudited. The unaudited interim condensed consolidated financial statements have been prepared on the same basis as the audited consolidated financial statements as of and for the year ended December 31, 2022, and, in the opinion of management, reflect all normal recurring adjustments necessary for the fair presentation of the Company’s financial position as of June 30, 2023 and December 31, 2022, results of operations for the three and six month periods ended June 30, 2023 and June 30, 2022, cash flows for the six month periods ended June 30, 2023 and June 30, 2022 and changes in stockholders’ deficit for the three month periods ended March 31, 2023 and 2022 and three month periods ended June 30, 2023 and 2022. The results of operations for the interim periods are not necessarily indicative of the results of operations to be expected for the year ending December 31, 2023. These unaudited interim condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements as of and for the year ended December 31, 2022, and notes thereto, which are included in the Company’s 2022 Form 10-K. Summary of Significant Accounting Policies As of June 30, 2023, the Company’s significant accounting policies and estimates, which are detailed in the Company’s 2022 Form 10-K, have not changed. Principles of Consolidation The accompanying unaudited condensed consolidated financial statements include the results of operations of Paratek Pharmaceuticals, Inc. and its wholly-owned subsidiaries, Paratek Pharma, LLC, Paratek Securities Corporation, Transcept Pharma, Inc., Paratek Ireland Limited, Paratek Royalty Corporation, Paratek Royalty Corporation II, PRTK SPV1 LLC and PRTK SPV2 LLC. All significant intercompany accounts and transactions have been eliminated in consolidation. Use of Estimates The preparation of the accompanying unaudited condensed consolidated financial statements in conformity with U.S. GAAP requires the Company to make estimates and judgments that affect the reported amounts of assets, liabilities, and expenses in the Company’s financial statements. On an ongoing basis, the Company evaluates its estimates and judgments, including those related to, among other items, accounts receivable and related reserves, inventory and related reserves, goodwill, net product revenue, government contract service revenue, government contract grant revenue, collaboration and royalty revenue, leases, stock-based compensation arrangements, amortization of the debt discount and issuance costs under the R-Bridge Loan Agreement (as defined below), manufacturing and clinical accruals, useful lives for depreciation and valuation allowances on deferred tax assets. Actual results could differ from those estimates. Changes in estimates are reflected in reported results in the period in which they become known by the Company’s management. Segment and Geographic Information Operating segments are defined as components of an enterprise engaging in business activities for which discrete financial information is available and regularly reviewed by the chief operating decision maker in deciding how to allocate resources and in assessing performance. The Company views its operations and manages its business in one operating segment. Concentration of Credit Risk Financial instruments that subject the Company to credit risk consist primarily of cash, restricted cash, and accounts receivable. The Company places its cash in an accredited financial institution and this balance is above federally insured amounts.

Earnings Per Share [Abstract] | |
Net Loss Per Share | Net Loss Per Share Basic net loss per share is calculated by dividing the net loss by the weighted-average number of common stock outstanding during the period, without consideration for common stock equivalents. Diluted net loss per share is computed by dividing the net loss by the weighted-average number of common share equivalents outstanding for the period determined using the treasury-stock method or the if-converted method, as applicable. For purposes of this calculation, shares of common stock issuable upon conversion of convertible debt, stock options, restricted stock units, or RSUs, warrants to purchase common stock, and shares issuable under the employee stock purchase plan are considered to be common stock equivalents and are only included in the calculation of diluted net loss per share when their effect is dilutive. Common equivalent shares result from stock options and RSUs, warrants to purchase shares of common stock, common stock issuable upon conversion of convertible debt and shares issuable under the employee stock purchase plan (the proceeds of which are then assumed to have been used to repurchase outstanding stock using the treasury stock method). The two-class method is used for outstanding warrants as it is considered to be a participating security, and it is more dilutive than the treasury stock method. The Company was in a net loss position as of June 30, 2023 and June 30, 2022. The following outstanding shares subject to stock options and RSUs, warrants to purchase shares of common stock, common stock issuable upon conversion of convertible debt and shares issuable under the Company’s employee stock purchase plan were antidilutive due to a net loss in the periods presented and, therefore, were excluded from the dilutive securities computation for the three and six months ended June 30, 2023 and 2022 as indicated below: June 30, 2023 2022 Excluded potentially dilutive securities (1): Common stock issuable under outstanding convertible notes 10,377,361 10,377,361 Shares subject to outstanding options to purchase common stock 1,347,183 2,119,588 Unvested restricted stock units 4,246,457 7,213,532 Shares subject to warrants to purchase common stock 426,866 426,866 Shares issuable under employee stock purchase plan 907,451 159,738 Totals 17,305,318 20,297,085 (1) The number of shares is based on the maximum number of shares issuable on exercise or conversion of the related securities as of June 30, 2023 and 2022. Such amounts have not been adjusted for the treasury-stock method or weighted-average outstanding calculations as required if the securities were dilutive. |

Organization, Consolidation and Presentation of Financial Statements [Abstract] | |
Government Contract Revenue | Government Contract Revenue Biomedical Advanced Research and Development Authority In December 2019, the Company entered into the BARDA contract, which is a five-year contract with an option to extend to ten years. The BARDA contract could result in payments to the Company of up to approximately $303.6 million and consists of a five-year base period-of-performance and a total contract period-of-performance (base period plus option exercises) of up to ten years. The BARDA contract supports the development of NUZYRA for the treatment of pulmonary anthrax, FDA post-marketing requirements, or PMRs, associated with the initial NUZYRA approval, and the ability for BARDA to procure up to 10,000 treatment courses of NUZYRA for use against potential biothreats. In September 2021, the Company and BARDA modified the original BARDA contract, herein referred to as the amended BARDA contract, to provide additional funding to expand the development of NUZYRA under an FDA Animal Efficacy Rule development program to support a supplemental New Drug Application, or sNDA, to the FDA to include post-exposure prophylaxis, or PEP, in addition to the treatment of pulmonary anthrax, herein referred to as the amended option. In July 2023, the Company and BARDA further modified the amended BARDA contract to provide new development milestones associated with the achievement of specific anthrax development milestones for the next BARDA procurement. BARDA and the Company have agreed the next procurement of NUZYRA anthrax treatment courses will be split into two equal procurements based on the achievement of specific development milestones toward both treatment and PEP indications of pulmonary anthrax. The first of these procurements will be triggered by the delivery of positive top-line data from a dose-ranging efficacy study for PEP of inhalation anthrax in non-human primates, or NHPs. The second of these procurements will be triggered by BARDA's receipt of positive top-line data from a combination of two studies: a dose-ranging efficacy study in NHPs and a pivotal efficacy study in rabbits for the treatment of inhalation anthrax. The trigger for the final procurement of NUZYRA continues to be the Company's receipt of sNDA approval from the FDA for the treatment of inhalation anthrax. Under the terms of the original BARDA contract, approximately $59.4 million was awarded to the Company by BARDA in December 2019 for the development of NUZYRA for the treatment of pulmonary anthrax and the purchase of an initial 2,500 treatment courses of NUZYRA. As part of this initial $59.4 million award, a $37.9 million procurement of NUZYRA was delivered to and accepted by BARDA in June 2021, and the amount earned from this procurement was recognized in net U.S. sales of NUZYRA during the three months ended June 30, 2021. The Company has been periodically drawing down the remaining $21.5 million of the initial award based on costs incurred during the development program. Two additional contractual services under the original BARDA contract were initiated by BARDA in March 2020 that awarded the Company approximately $76.8 million for reimbursement of existing FDA PMRs and approximately $20.4 million for reimbursement of manufacturing-related requirements, which the Company has been drawing down based on costs incurred. This additional staged funding is expected to support all FDA PMRs associated with the approval of NUZYRA, including CABP and pediatric studies, as well as a five-year post-marketing bacterial surveillance study, and support the U.S. onshoring and security requirements of the Company’s manufacturing activities for NUZYRA. BARDA initiated the amended option in September 2021 that expanded the development of NUZYRA under an FDA Animal Efficacy Rule development program to support an sNDA that will include PEP in addition to the treatment of pulmonary anthrax for a revised total of approximately $31.6 million. A second procurement, the purchase of an additional 2,500 treatment courses of NUZYRA for a total of $36.4 million, was delivered to and accepted by BARDA in December 2022. The amount earned from this procurement was recognized in net U.S. sales of NUZYRA during the three months ended December 31, 2022. The remaining options under the amended BARDA contract include a maximum of approximately $79.0 million to provide for additional purchases of NUZYRA anthrax treatment courses, each of which may be exercised at BARDA’s discretion upon achievement of specific development milestones related to the anthrax treatment development program. The BARDA contract contains a number of terms and conditions that are customary for government contracts of this nature, including provisions giving the government the right to terminate the contract at any time for its convenience. The Company evaluated the BARDA contract under ASC, Topic 606, Revenue from Contracts with Customers, or ASC 606, and concluded that a portion of the arrangement represents a transaction with a customer. The Company identified five material promises under the BARDA contract: (i) research and development services performed for the treatment of pulmonary anthrax, (ii) the procurement of 2,500 treatment courses of NUZYRA, (iii) an option for services performed for the supplemental late-stage development of NUZYRA for treatment and prophylaxis of pulmonary anthrax, (iv) an option for services related to U.S. manufacturing onshoring and security requirements, which includes shelf-life stability extension work and regulatory activities that will benefit the manufacturing processes that support NUZYRA for the treatment of pulmonary anthrax, and (v) options to procure up to three tranches of up to 2,500 anthrax treatment courses of NUZYRA each. In December 2019, the Company determined material promises (i) and (ii) above were performance obligations since they were distinct within the context of the contract as the services are separately identifiable from other promises within the arrangement. The Company also determined that for (i) and (ii) the transaction price included within the BARDA contract was equivalent to the standalone selling price of the services and the cost of the procurement. The Company evaluated the material promises that contained option rights ((iii), (iv), and (v) above). The Company determined that (iii) and (iv) were not offered at a discount that is incremental to the range of discounts typically given for these goods and services, and therefore do not represent material rights. As such, options for additional services in (iii) and (iv) were not considered performance obligations at the outset of the arrangement. The Company also evaluated the future procurement option rights (v) and determined that those option rights represent a material right. As such, the optional additional NUZYRA procurements in (v) were considered performance obligations at the outset of the arrangement. The Company concluded that three performance obligations existed at the outset of the BARDA contract. As the BARDA contract is partially within the scope of ASC 606 and partially within the scope of other guidance, the Company applied the guidance of ASC 606 to initially measure the parts of the contract to which ASC 606 is applicable. The total transaction price of the parts of the BARDA contract that existed at the outset of the contract that fall under ASC 606 was determined to be $63.6 million, inclusive of $4.2 million in variable consideration and was allocated to each of the three performance obligations based on the performance obligation’s estimated relative stand-alone selling prices. The transaction price was allocated as follows: $21.5 million to research and development services performed for the treatment of pulmonary anthrax in (i), which will be classified as government contract service revenue when recognized, $37.9 million to the procurement of 2,500 treatment courses of NUZYRA in (ii), which was classified as product revenue when recognized, and a total of $4.2 million to the options to procure up to three 2,500 treatment courses of NUZYRA in (v), which will be included within product revenue when recognized upon exercise and transfer of control of related treatment courses. The Company estimated the stand-alone selling price of the research and development services performed for the treatment of pulmonary anthrax based on the Company’s projected cost of providing the services plus an applicable profit margin commensurate with observable market data for similar services. The Company estimated the stand-alone selling price of the procurement of 2,500 treatment courses of NUZYRA based on historical pricing of the Company’s commercial products to similar customers. The Company estimated the stand-alone selling price of the future procurement options based on the discount that the customer would obtain when exercising the option, adjusted for any discount that the customer could receive without entering into the contract, and the likelihood that the option will be exercised. The Company’s performance obligations are either satisfied over time as work progresses or at a point in time. The Company concluded that research and development services performed for the treatment of pulmonary anthrax in (i) would be recognized as government contract service revenue over time as the performance obligation is satisfied. Costs incurred represent work performed, which corresponds with, and thereby best depicts, the transfer of control to the customer. Types of contract costs include labor, material, and third-party services. The product procurement performance obligations (ii) and, if any optional additional procurements are exercised from (v) above), generate revenue at a point in time, upon transfer of control of the product. As such, the related revenue for these performance obligations is recognized at a point in time as product revenue within the Company’s consolidated statement of operations. As of December 31, 2021, the product procurement performance obligation (ii) was completed and $37.9 million of product revenue was earned and recognized due to the delivery and acceptance of the first procurement under the BARDA contract. In April 2020, BARDA exercised its option to obtain manufacturing-related services under material promise (iv) and the Company is treating these services as a separate $20.4 million contract for accounting purposes since manufacturing-related services were determined at the contract outset to be optional services that did not represent a material right. The Company’s manufacturing-related services are satisfied over time as work progresses. In September 2021, BARDA exercised the amended option under the amended BARDA contract, to fund an FDA Animal Rule development program to support an sNDA to include PEP against, in addition to the treatment of, pulmonary anthrax. The Company is treating these services as a separate $31.6 million contract for accounting purposes since the completion of a late-stage development program was determined at the contract outset to be optional services that did not represent a material right. The additional services added as part of the amended option were distinct and the increased transaction price is reflective of the entity’s standalone selling prices of the additional promised services. The Company’s late-stage development program obligations are satisfied over time as work progresses. Research and development services performed under the amended option will be recognized as government contract service revenue over time as the performance obligation is satisfied. The Company recognized $5.3 million and $4.1 million of government contract service revenue under the BARDA contract during the six months ended June 30, 2023 and June 30, 2022, respectively. The Company recognized $3.6 million and $1.9 million of government contract service revenue under the BARDA contract during the three months ended June 30, 2023 and June 30, 2022, respectively. As of June 30, 2023, the aggregate amount of transaction price allocated to remaining performance obligations, excluding unexercised contract options, was $52.6 million. The Company expects to recognize this amount as revenue over the next three The Company concluded that BARDA’s reimbursement for existing FDA PMRs associated with the initial NUZYRA approval was not within the scope of ASC 606 as BARDA is not receiving services as the Company’s customer. The Company estimated the consideration to be allocated to government contract grant revenue based on the consideration under the BARDA contract in excess of the estimated standalone selling prices for components of the BARDA contract accounted for under ASC 606. The Company recognizes the allocated consideration for BARDA’s reimbursement of existing FDA PMRs associated with the initial NUZYRA approval of $72.6 million as government contract grant revenue as the related reimbursable expenses are incurred. The Company recognized $4.1 million and $4.2 million of government contract grant revenue under the BARDA contract during the six months ended June 30, 2023 and June 30, 2022, respectively. The Company recognized $1.9 million and $2.1 million of government contract grant revenue under the BARDA contract during the three months ended June 30, 2023 and June 30, 2022, respectively. Contract Balances Contract assets (i.e., unbilled accounts receivable) and/or contract liabilities (i.e., customer advances and deposits) may exist at the end of each reporting period under the BARDA contract. When amounts are received prior to performance obligations being satisfied, the amounts allocated to those performance obligations are reflected as contract liabilities on the consolidated balance sheets, as deferred revenue, until the performance obligations are satisfied. As of June 30, 2023, $0.3 million of unbilled accounts receivable was recorded and is a component of accounts receivable, net on the Company’s condensed consolidated balance sheet. As of December 31, 2022, $1.0 million of unbilled accounts receivable was recorded and is a component of accounts receivable, net on the Company’s condensed consolidated balance sheet. As of June 30, 2023 and December 31, 2022, there was no deferred revenue recorded as a component of other current liabilities on the Company’s condensed consolidated balance sheet associated with the BARDA contract. The Company recognized the deferred revenue balance into net NUZYRA product revenue upon delivery of the second BARDA procurement in December 2022. In conjunction with the second NUZYRA procurement, the Company also recorded a $0.3 million contract asset, as a component of prepaid and other current assets, on the Company's consolidated balance sheet as of December 31, 2022. As of June 30, 2023, an insignificant net contract asset was recorded as a component of prepaid and other current assets on the Company's consolidated balance sheet. |

License and Collaboration Agreements | License and Collaboration Agreements Tetraphase Pharmaceuticals, Inc. In March 2019, Paratek and Tetraphase Pharmaceuticals, Inc., or Tetraphase, which later became a subsidiary of La Jolla Pharmaceutical Company, both of which are now a subsidiary of Innoviva, Inc, entered into a License Agreement, or the Tetraphase License Agreement. Under the terms of the Tetraphase License Agreement, Paratek granted to Tetraphase a non-exclusive, worldwide, royalty-bearing license, with the right to grant sublicenses, under certain Paratek patents, to develop, make, have, use, import, offer for sale and sell the licensed product, or XERAVA TM , a drug for the treatment of complicated, intra-abdominal infections caused by bacteria, which was approved by the FDA in August 2018. The terms of the Tetraphase License Agreement provide for Tetraphase to pay Paratek royalties at a low single digit percent on net product revenues of the licensed product sold in the U.S. Tetraphase’s obligation to pay royalties with respect to the licensed product shall be retroactive to the date of the first commercial sale of the licensed product in the U.S., which occurred in February 2019. La Jolla is currently selling XERAVA TM (Eravacycline) in the U.S. The Tetraphase License Agreement will continue until the expiration of and payment by Tetraphase of all Tetraphase's payment obligations, which is when there are no longer any valid claims of the licensed Paratek patents that would be infringed, in the absence of a license, by a manufacture, use, or sales of the licensed product. The principal licensed patent under the Tetraphase License Agreement is expected to expire in October 2023. In accordance with the Company’s revenue recognition policy, the Company recognized an insignificant amount of royalty revenue during the three and six months ended June 30, 2023 and June 30, 2022 under the Tetraphase License Agreement. Zai Lab (Shanghai) Co., Ltd. In April 2017, Paratek Bermuda Ltd., a former wholly-owned subsidiary of Paratek Pharmaceuticals, Inc., and Zai entered into a License and Collaboration Agreement, or the Zai Collaboration Agreement. On December 18, 2019, Paratek Bermuda Ltd. assigned its rights under the Zai Collaboration Agreement to Paratek Pharmaceuticals, Inc. Under the terms of the Zai Collaboration Agreement, Paratek granted Zai an exclusive license to develop, manufacture and commercialize omadacycline, or the licensed product, in the People’s Republic of China, Hong Kong, Macau and Taiwan, or the Zai territory, for all human therapeutic and preventative uses other than biodefense. Zai is responsible for the development, manufacturing and commercialization of the licensed product in the Zai territory, at its sole cost with certain assistance from Paratek. Under the terms of the Zai Collaboration Agreement, Paratek earned an upfront cash payment of $7.5 million in April 2017, $5.0 million upon approval by the FDA of a NDA submission in the CABP indication in October 2018, $3.0 million upon submission of the first regulatory approval application for a licensed product in the People’s Republic of China in December 2019, and a $6.0 million milestone payment upon regulatory approval of omadacycline for the treatment of adults with ABSSSI and CABP in the People’s Republic of China in December 2021. Paratek is also eligible to receive up to $40.5 million in potential future commercial milestone payments. The terms of the Zai Collaboration Agreement also provide for Zai to pay Paratek tiered royalties at a low double digit to mid-teen percent on net sales of the licensed product in the Zai territory. The Zai Collaboration Agreement will continue, on a region-by-region basis, until the expiration of and payment by Zai of all Zai’s payment obligations, which is until the later of: (i) the abandonment, expiry or final determination of invalidity of the last valid claim within the Paratek patents that covers the licensed product in the region in the Zai territory in the manner that Zai or its affiliates or sublicensees exploit the licensed product or intend for the licensed product to be exploited; or (ii) 2032, the eleventh anniversary of the first commercial sale of such licensed product in such region. The Company evaluated the Zai Collaboration Agreement under ASC 606. The Company determined that there were six material promises under the Zai Collaboration Agreement: (i) an exclusive license to develop, manufacture and commercialize omadacycline in the Zai territory, (ii) the initial technology transfer (iii) a transfer of certain materials and materials know-how, (iv) optional manufacturing services, (v) optional regulatory support and (vi) optional commercialization support. The Company determined that the exclusive license and initial technology transfer were not distinct from one another, as the license has limited value without the transfer of the Company’s technology, which will allow Zai to develop the manufacturing process and commercialize omadacycline in the Zai territory in the timeline anticipated under the agreement. Without the technology transfer, Zai would incur additional costs to recreate the Company’s know-how. Therefore, the license and initial technology transfer are combined as a single performance obligation. The transfer of materials is a single distinct performance obligation. The Company evaluated the option rights for manufacturing services, regulatory support and commercialization support to determine whether they represent or include material rights to Zai and concluded that the options were not issued at a discount, and therefore do not represent material rights. As such, they are not considered performance obligations at the outset of the arrangement. Based on these assessments, the Company determined that two performance obligations existed at the outset of the Zai Collaboration Agreement: (i) the exclusive license combined with the initial technology transfer and (ii) the transfer of certain materials. The Company has recognized $21.5 million in milestone revenue, as described above, under the Zai Collaboration Agreement as of June 30, 2023. The performance obligation to deliver the license was satisfied in 2017 and research and development services were completed by December 2021. Milestone payments are recognized as revenue when the risk of significant reversal is resolved, generally when the milestone event occurs. Therefore, the $6.0 million milestone payment upon regulatory approval of NUZYRA in the People’s Republic of China was recognized in December 2021. As of June 30, 2023 and December 31, 2022 there was no deferred revenue recorded as a component of other current liabilities on the Company’s condensed consolidated balance sheet associated with the Zai Collaboration Agreement. Almirall, LLC In July 2007, the Company and Warner Chilcott Company, Inc. (which became a part of Allergan plc, or Allergan), entered into a collaborative research and license agreement under which the Company granted Allergan an exclusive license to research, develop, manufacture and commercialize tetracycline products for use in the U.S. for the treatment of acne and rosacea. In September 2018, Allergan assigned to Almirall, its rights under the collaboration agreement, or the Almirall Collaboration Agreement. Since Allergan did not exercise its development option with respect to the treatment of rosacea prior to initiation of a Phase 3 trial for the product, the license grant to Allergan, which was assigned to Almirall, converted to a non-exclusive license for the treatment of rosacea as of December 2014. Under the terms of the Almirall Collaboration Agreement, Almirall is responsible for and is obligated to use commercially reasonable efforts to develop and commercialize tetracycline compounds that are specified in the agreement for the treatment of acne. The Company has agreed during the term of the Almirall Collaboration Agreement not to directly or indirectly develop or commercialize any tetracycline compounds in the U.S. for the treatment of acne, and Almirall has agreed during the term of the Almirall Collaboration Agreement not to directly or indirectly develop or commercialize any tetracycline compound included as part of the agreement for any use other than as provided in the Almirall Collaboration Agreement. In February 2020, the Company finalized a license agreement with Almirall granting the Company exclusive rights to develop, manufacture and commercialize sarecycline outside of the U.S., including rights of reference to Almirall’s clinical data thus formalizing the Company’s rights to develop, manufacture and commercialize sarecycline in the rest of the world. In connection with that license, the Company then exclusively licensed Almirall pursuant to the Almirall China License Agreement, the rights to develop, manufacture and commercialize sarecycline in the greater China region. Almirall currently holds a nonexclusive license to develop and commercialize sarecycline for the treatment of rosacea in the U.S., and in the U.S., Paratek cannot grant rights on back-up compounds, lead candidate(s), or products licensed to Almirall for rosacea. The Almirall Collaboration Agreement contains two performance obligations: (i) an exclusive license to research, develop and commercialize tetracycline products for use in the U.S. for the treatment of acne and non-exclusive rights to rosacea and (ii) research and development services. The performance obligation to deliver the license was satisfied upon execution of the Almirall Collaboration Agreement in July 2007. All research and development services were completed by December 2010. The options provided to Almirall for additional development services do not provide Almirall with a material right as these services will not be provided at a significant or incremental discount. As such, the option services are not performance obligations. As the performance obligation to deliver the license was satisfied in 2007 and research and development services were completed by December 2010, all subsequent milestone payments are recognized as revenue when the risk of significant reversal is resolved, generally when the milestone event occurs. The Company recognized all Almirall milestones in prior years. There are no milestones left to be recognized under the Almirall Collaboration Agreement. Almirall is also obligated to pay the Company tiered royalties, ranging from the mid-single digits to the low double digits, based on net sales of tetracycline compounds developed under the Almirall Collaboration Agreement, with a standard royalty reduction post patent expiration for such product for the remainder of the royalty term. Royalty payments are recognized when the sales occur. During the six months ended June 30, 2023 and June 30, 2022, the Company recognized $0.6 million and $0.9 million of royalty revenue, respectively, for sales of SEYSARA in the U.S. by Almirall under the Almirall Collaboration Agreement. During the three months ended June 30, 2023 and June 30, 2022, the Company recognized $0.1 million and $0.4 million of royalty revenue, respectively, for sales of SEYSARA in the U.S. by Almirall under the Almirall Collaboration Agreement. Royalty revenue recognized for sales of SEYSARA in the U.S. is estimated using third-party data and an approximation of discounts and allowances to calculate net product sales, to which the Company then applies the applicable royalty percentage specified in the Almirall Collaboration Agreement. Differences between actual and estimated royalty revenues are adjusted for in the period in which they become known, which is expected to be the following quarter. In February 2020, the Company entered into (i) an ex-U.S. license agreement with Almirall, or the Ex-U.S. License, which grants the Company an exclusive license in and to certain technology owned or in-licensed by Almirall or its affiliates in order to research, develop, manufacture and commercialize sarecycline for the treatment of acne in all countries other than the U.S. and (ii) a license agreement with Almirall that is specific to the greater China region, or the China License, under which we granted to Almirall an exclusive license in and to certain technology owned or in-licensed by the Company or its affiliates in order to research, develop and commercialize sarecycline for the treatment of acne in the greater China region. Under the terms of the China License, Almirall is responsible for and is obligated to use commercially reasonable efforts to develop and commercialize sarecycline for the treatment of acne, including requirements to (i) file an Investigational New Drug Application (or analogous foreign submission) for sarecycline for the treatment of acne in the greater China region in calendar year 2020, (ii) receive regulatory approval for sarecycline for the treatment of acne in the greater China region within seven years following such submission and (iii) commercialize sarecycline for the treatment of acne in the greater China region within eighteen months after obtaining regulatory approval. If Almirall does not satisfy the diligence requirements set forth in subclauses ii or iii above, we may terminate the China License. In connection with the Ex-U.S. License, the Company pays Almirall, on a country-by-country and product-by-product basis, (i) for eight years following the first commercial sale of a sarecycline product in a country, a royalty in the middle-single digits on its or its affiliates’ nets sales of sarecycline products outside of the U.S., subject to certain standard reductions, and (ii) for fifteen years following the first commercial sale of a sarecycline product in a country, a percentage of the consideration (e.g., milestones, royalties) we receive from sublicensees in connection with developing and commercializing sarecycline outside of the U.S., which ranges from one-fifth to one-half of such consideration, subject to certain standard reductions. In connection with the China License, for fifteen years following the first commercial sale of a sarecycline product in China, Almirall pays the Company a royalty in the high-single digits on their, their affiliates’ or their sublicensees’ net sales of sarecycline products in the greater China region, subject to certain standard reductions. Tufts University In February 1997, the Company and Tufts University, or Tufts, entered into a license agreement under which the Company acquired an exclusive license to certain patent applications and other intellectual property of Tufts related to the drug resistance field to develop and commercialize products for the treatment or prevention of bacterial or microbial diseases or medical conditions in humans or animals or for agriculture. The Company subsequently entered into eleven amendments to that agreement, or collectively the Tufts License Agreement, to include patent applications filed after the effective date of the original license agreement, to exclusively license additional technology from Tufts, to expand the field of the agreement to include disinfectant applications, and to change the royalty rate and percentage of sublicense income paid by the Company to Tufts under sublicense agreements with specified sublicensees. The Company is obligated under the Tufts License Agreement to provide Tufts with annual diligence reports and a business plan and to meet certain other diligence milestones. The Company has the right to grant sublicenses of the licensed rights to third parties, which will be subject to the prior approval of Tufts unless the proposed sublicensee meets a certain net worth or market capitalization threshold. The Company is primarily responsible for the preparation, filing, prosecution and maintenance of all patent applications and patents covering the intellectual property licensed under the Tufts License Agreement at its sole expense. The Company has the first right, but not the obligation, to enforce the licensed intellectual property against infringement by third parties. The Company issued Tufts 1,024 shares of the Company’s common stock on the date of execution of the original license agreement, and the Company was required to make certain payments of up to $0.3 million to Tufts upon the achievement by products developed under the agreement of specified development and regulatory approval milestones. The Company made a payment of $50,000 to Tufts for achieving the first milestone following commencement of the Phase 3 clinical trial for omadacycline and a payment of $100,000 to Tufts for achieving the second milestone following its first marketing application submitted in the U.S. The third, and final, payment of $150,000 became due upon FDA approval of omadacycline in October 2018. The Company is also obligated to pay Tufts a minimum royalty payment in the amount of $25,000 per year. In addition, the Company is obligated to pay Tufts royalties based on gross sales of products, as defined in the agreement, ranging in the low single digits depending on the applicable field of use for such product sale. If the Company enters into a sublicense under the agreement, based on the applicable field of use for such product, the Company will be obligated to pay Tufts (i) a percentage, ranging from 10% to 14% (ten percent to fourteen percent) for compounds other than omadacycline, and a percentage in the single digits for the compound omadacycline, of that portion of any sublicense issue fees or maintenance fees received by the Company that are reasonably attributable to the sublicense of the rights granted to the Company under the Tufts License Agreement and (ii) the lesser of (a) a percentage, ranging from the low tens to the high twenties based on the applicable field of use for such product, of the royalty payments made to the Company by the sublicensee or (b) the amount of royalty payments that would have been paid by the Company to Tufts if it had sold the product. Unless terminated earlier, the Tufts License Agreement will expire at the same time as the last-to-expire patent in the patent rights licensed to the Company under the agreement and after any such expiration the Company will continue to have an exclusive, fully-paid-up license to such intellectual property licensed from Tufts. Tufts has the right to terminate the agreement upon 30 days’ notice should the Company fail to make a material payment under the Tufts License Agreement or commit a material breach of the agreement and not cure such failure or breach within such 30-day period, or if, after the Company has started to commercialize a product under the Tufts License Agreement, the Company ceases to carry on its business for a period of 90 consecutive days. The Company has the right to terminate the Tufts License Agreement at any time upon 180 days’ notice. During the six months ended June 30, 2023 and June 30, 2022, the Company incurred $0.9 million and $0.7 million of royalty expense, respectively, under the Tufts License Agreement. During the three months ended June 30, 2023 and June 30, 2022, the Company incurred $0.5 million and $0.4 million of royalty expense, respectively, under the Tufts License Agreement. Past Collaborations Novartis International Pharmaceutical Ltd. In September 2009, the Company and Novartis International Pharmaceutical Ltd., or Novartis, which merged into Novartis Pharma AG, a wholly owned subsidiary of Novartis AG, entered into a Collaborative Development, Manufacture and Commercialization License Agreement, or the Novartis Agreement, which provided Novartis with a global, exclusive patent and technology license for the development, manufacturing and marketing of omadacycline. The Novartis Agreement was terminated by Novartis without cause in June 2011 and the termination was effective 60 days later. The Company and Novartis subsequently entered in a letter agreement in January 2012, or the Novartis Letter Agreement, as amended, pursuant to which we reconciled shared development costs and expenses and granted Novartis a right of first negotiation with respect to commercialization rights of omadacycline following approval of omadacycline from the FDA, European Medicines Agency, or EMA, or any regulatory agency, but only to the extent the Company had not previously granted such commercialization rights related to omadacycline to another third-party as of any such approval. The Company also agreed to pay Novartis a 0.25% royalty, to be paid from net sales received by the Company in any country following the launch of omadacycline in that country and continuing until the later of expiration of the last active valid patent claim covering such product in the country of sale and 10 years from the date of first commercial sale in such country. The first royalty payment became payable as of March 31, 2019. The amended Novartis Letter Agreement resulted in a long-term liability in the amount of $2.3 million and $2.5 million as of June 30, 2023 and December 31, 2022, respectively, included within “Other Liabilities” on the Company’s consolidated balance sheet. In addition, short-term liabilities of $0.4 million and $0.4 million included within “Other Current Liabilities” on our consolidated balance sheets as of June 30, 2023 and December 31, 2022, respectively, represent the portion of royalty payments due to Novartis within twelve months of each balance sheet date. There are no other payment obligations under the Novartis Agreement or the amended Novartis Letter Agreement.

Fair Value Measurements | Fair Value Measurements Financial instruments, including cash, cash equivalents, restricted cash, money market funds, U.S. treasury securities, accounts receivable, accounts payable, and accrued expenses are carried on the condensed consolidated financial statements at amounts that approximate fair value. The fair value of the Company’s long-term debt is determined using current applicable rates for similar instruments as of the balance sheet date. The fair value of the Company’s debt (including the Notes as defined in Note 13, Debt) , was $256.5 million as of June 30, 2023 and $227.2 million as of December 31, 2022. The fair value of the Company’s debt was determined using Level 2 inputs. Fair values are based on assumptions concerning the amount and timing of estimated future cash flows and assumed discount rates, reflecting varying degrees of perceived risk. There were no financial assets and liabilities measured at fair value as of June 30, 2023 and December 31, 2022. |

Stock-Based and Incentive Compensation | Stock-Based and Incentive Compensation Stock-based Compensation The following table presents stock-based compensation expense included in the Company’s condensed consolidated statements of operations and comprehensive income (loss) (in thousands): Three Months Ended Six Months Ended 2023 2022 2023 2022 Research and development expense $ 308 $ 515 $ 614 $ 692 Selling, general and administrative expense 1,918 3,371 3,758 5,662 Total stock-based compensation expense $ 2,226 $ 3,886 $ 4,372 $ 6,354 Stock-based compensation expense is estimated as of the grant date based on the fair value of the award and is recognized as expense over the requisite service period, which generally represents the vesting period. The Company estimates the fair value of its stock options using the Black-Scholes option-pricing model. The weighted-average assumptions used to determine the fair value of the stock option grants is as follows: Six Months Ended June 30, 2023 2022 Volatility 66.6 % 62.2 % Risk-free interest rate 3.8 % 2.3 % Expected dividend yield 0.0 % 0.0 % Expected life of options (in years) 6.1 5.9 Stock Plan Activity The Company’s Board of Directors adopted the Paratek Pharmaceuticals, Inc. 2015 Equity Incentive Plan, or the 2015 Plan, which was approved by Company stockholders at the annual meeting of stockholders held on June 9, 2015. As of June 30, 2023, there are 4,545,170 shares available for future issuance under the 2015 Plan. The Company recognizes the stock-based compensation expense of awards subject to performance-based vesting conditions over the requisite service period, to the extent achievement of the performance condition is deemed probable relative to targeted performance using the accelerated attribution method. A change in the requisite service period that does not change the estimate of the total stock-based compensation expense (i.e., it does not affect the grant-date fair value or quantity of awards to be recognized) is recognized prospectively over the remaining requisite service period. During the six months ended June 30, 2023, the Company’s Board of Directors granted 140,000 RSUs to directors of the Company under the 2015 Plan. The RSU awards granted to directors of the Company during the six months ended June 30, 2023, are subject to time-based vesting over a period of one Performance-based RSU, or PRSU, awards granted to certain executives and employees of the Company in prior years remained outstanding and probable as of June 30, 2023, and will vest as follows: 15/55 of the February 2020 grants will vest on achievement of certain clinical milestones related to NUZYRA, and 25/55 and 10/55 of the March 2021 grants will vest on certain net product revenue achievements and on achievement of certain clinical milestones related to NUZYRA, respectively. The Company’s Board of Directors adopted the Paratek Pharmaceuticals, Inc. 2015 Inducement Plan, or the 2015 Inducement Plan, in accordance with Nasdaq Rule 5635(c)(4), reserving 360,000 shares of common stock solely for the grant of inducement stock options to employees entering into employment or returning to employment after a bona fide period of non-employment with the Company. The Company has not made any grants under the 2015 Inducement Plan since December 31, 2015. Although the Company does not currently anticipate the issuance of additional grants under the 2015 Inducement Plan, as of June 30, 2023, 341,500 shares remain available for grant under that plan, as well as any shares underlying outstanding stock options that may become available for grant pursuant to the plan’s terms. It is therefore possible that the Company may, based on the business and recruiting needs of the Company, issue additional stock options under the 2015 Inducement Plan. In June 2017, the Company’s Board of Directors adopted the Paratek Pharmaceuticals, Inc. 2017 Inducement Plan, or the 2017 Inducement Plan, in accordance with Nasdaq Rule 5635(c)(4), reserving 550,000 shares of common stock solely for the grant of inducement stock options to employees entering into employment or returning to employment after a bona fide period of non-employment with the Company. In October 2018 and March 2022, the Company’s Board of Directors approved the reserve of an additional 500,000 shares and 750,000 shares, respectively, for the 2017 Inducement Plan, for a total of 1,800,000 shares reserved for issuance under it. During the six months ended June 30, 2023, the Company’s Board of Directors granted 8,400 stock options and 7,000 RSU awards to employees of the Company under the 2017 Inducement Plan. The stock option awards are generally subject to time-based vesting over a period of one Stock Options A summary of stock option activity for the six months ended June 30, 2023 is as follows: Number of Shares Weighted Average Exercise Price Weighted Average Remaining Contractual Term (in years) Aggregate Intrinsic Value (in thousands) Outstanding at December 31, 2022 1,374,152 $ 11.14 5.84 Granted 8,400 $ 1.99 Exercised — $ — Cancelled or forfeited (35,369) $ 6.61 Outstanding at June 30, 2023 1,347,183 $ 11.20 5.31 $ — Exercisable at June 30, 2023 1,124,469 $ 12.67 4.68 $ — The total intrinsic value of stock options granted, cancelled or forfeited was insignificant for the six months ended June 30, 2023. Restricted Stock Units A summary of RSU activity for the six months ended June 30, 2023 is as follows: Number of Shares Weighted Average Grant Date Fair Value Unvested balance at December 31, 2022 4,752,538 $ 5.10 Granted 147,000 2.05 Released (630,680) 4.38 Forfeited (22,401) 3.51 Unvested balance at June 30, 2023 4,246,457 $ 5.11 Total unrecognized stock-based compensation expense for all stock-based awards was $6.8 million as of June 30, 2023. This amount will be recognized over a weighted-average period of 1.14 years. 2009 Employee Stock Purchase Plan In June 2009, at the annual meeting of stockholders, the stockholders of the Company approved the 2009 Employee Stock Purchase Plan, or the 2009 ESPP. As of June 30, 2023, 36,539 shares were available for issuance under the 2009 ESPP. Since the merger involving privately-held Paratek Pharmaceuticals, Inc. and Transcept Pharmaceuticals, Inc., the Company has not made the 2009 ESPP available to employees. 2018 Employee Stock Purchase Plan The Company’s Board of Directors adopted, and in June 2018 Company’s stockholders approved, the Paratek Pharmaceuticals, Inc. 2018 Employee Stock Purchase Plan, or the 2018 ESPP. The 2018 ESPP was amended in October 2018 to change the commencement dates of the offering periods. The maximum aggregate number of shares of the Company’s common stock that may be purchased under the 2018 ESPP is 943,294 shares, or the ESPP Share Pool, subject to adjustment as provided for in the 2018 ESPP. The ESPP Share Pool represented 3% of the total number of shares of our common stock outstanding as of March 31, 2018. The 2018 ESPP allows eligible employees to purchase shares during certain offering periods, which will be six-month periods commencing June 1 and ending November 30 and commencing December 1 and ending May 31 of each year. The first offering under the 2018 ESPP was December 1, 2018. On June 6, 2023, the Company's stockholders approved the Amended and Restated Employee Stock Purchase Plan, which increased the number of authorized shares of common stock under the plan from 943,294 to 1,793,067 shares. As of June 30, 2023, 870,912 shares remained available for issuance under the 2018 ESPP. Revenue Performance Incentive Plan On October 4, 2018, the Company adopted the Revenue Performance Incentive Plan, or the Plan, to grant performance-based cash incentive awards to key employees and consultants of the Company. The Plan provides for an incentive pool of up to $50.0 million, plus accrued interest during the period between the awards’ vesting date and payment dates. Each participant will be allocated a percentage of the incentive pool. The incentive pool will be divided into two equal tranches with the first tranche vesting upon the Company’s achievement of cumulative net product revenues over $300.0 million by December 31, 2025, or Tranche 1, and the second tranche vesting upon the Company’s achievement of cumulative product revenues over $600.0 million by December 31, 2026, or Tranche 2. Participants will vest annually in each tranche of their awards in four equal installments on December 31, 2019, December 31, 2020, December 31, 2021, and December 31, 2022, subject to their continued employment with the Company through the applicable vesting date. Participants subsequently added to the plan, will vest on a weighted basis over three years, subject to their continued employment with the Company through the applicable vesting date. Upon the achievement of a Tranche 1 or Tranche 2 milestone (but not a deemed achievement in connection with a change of control), each participant who has remained in continuous employment with the Company through December 31, 2022 will be 100% vested in the applicable tranche. In the event of a change of control of the Company prior to December 31, 2026, participants whose employment has terminated prior to such date will be eligible for payouts under the Plan based on the then-vested portion of their awards, and participants who have remained employed through the change of control will be deemed to have time vested in full in each tranche of their awards. Upon the achievement of a Tranche 1 or Tranche 2 milestone (but not a deemed achievement in connection with a change of control), each participant’s payout in respect of the applicable tranche of his or her award will equal (a) the participant’s then-vested percentage, multiplied by (b) $25 million, multiplied by (c) the participant’s individual percentage allocation of the incentive pool. If a change of control occurs prior to December 31, 2026, and the Tranche 1 milestone was not achieved prior to the change of control, the Tranche 1 milestone will be deemed to be achieved at a percentage equal to the greater of (1) 50% and (2) the cumulative product revenues as of the change of control, divided by $300.0 million. If a change of control occurs prior to December 31, 2026, and the Tranche 2 milestone was not achieved prior to the change of control, the Tranche 2 milestone will be deemed to be achieved at a percentage equal to the greater of (1) 30% and (2) the cumulative product revenues as of the change of control, divided by $600.0 million. A participant’s payout in respect of each tranche of his or her award in a change of control will equal (1) the participant’s then-vested percentage of such tranche, multiplied by (2) the percentage of that tranche’s milestone that has been achieved or is deemed to have been achieved, multiplied by (3) $25.0 million, multiplied by (4) the participant’s individual percentage allocation of the incentive pool. The Tranche 1 milestone vested on January 31, 2023, upon the Company's achievement of cumulative net product revenues over $300.0 million. Amounts payable from the achievement of the Tranche 1 milestone will be paid in a lump-sum in the first quarter of 2026 and amounts that become payable upon achievement of the Tranche 2 milestone will be paid in a lump-sum in the first quarter of 2027. In the event of a change of control, any portion of the incentive pool that is earned, but unpaid, or deemed earned in connection with the change of control will be paid at the time of the change of control. If a change of control occurs prior to the achievement of either or both of the Tranche 1 and Tranche 2 milestones, the awards will remain outstanding and the remaining unpaid portion of the incentive pool applicable to the Tranche 1 or Tranche 2 milestone, as applicable, will be paid following the achievement of either such milestone at the time or times the awards would otherwise be paid out. Any successor in interest to the Company upon or following a change of control will be required to assume all obligations under the Plan. Awards may be paid out in cash or in a combination of cash and registered securities of equal value (based on the Company’s 20-day trailing average closing common stock price), with the portion paid in registered securities not to exceed 50% of the aggregate payment amount with respect to each tranche; provided, however, that any amounts that are immediately payable on closing with respect to an award in connection with a change in control will be paid in cash. The Company recognizes the compensation cost over the requisite service period, to the extent achievement of the performance condition is deemed probable relative to targeted performance. The performance condition under Tranche 1 of the Plan was deemed probable during 2 021. The performance condition under Tranche 2 was deemed probable during 2022. Accordingly, approximately $0.6 million of com pensation expense was recognized during the six months ended June 30, 2023. Compensation expense of $0.5 million was recognized during the six months ended June 30, 2022. Compensation cost of $45.9 million and $45.3 million is included in accrued long-term compensation in the Company’s consolidated balance sheet as of June 30, 2023 and December 31, 2022, respectively. Accrued interest of $0.7 million is included in accrued long-term compensation in the Company's consolidated balance sheet as of June 30, 2023. No accrued interest existed as of December 31, 2022 as the achievement of the Tranche 1 milestone occurred during the six months ended June 30, 2023. |

Debt Disclosure [Abstract] | |
Debt | Debt Long-Term Debt R-Bridge Loan Agreement On December 31, 2020, or the Closing Date, the Company, through its wholly-owned subsidiary PRTK SPV2 LLC, a Delaware limited liability company, or the Subsidiary, entered into a royalty and revenue interest-backed loan agreement, or the R-Bridge Loan Agreement, with an affiliate of R-Bridge Healthcare Investment Advisory, Ltd., or the R-Bridge Lender. Pursuant to the terms of the R-Bridge Loan Agreement, the Subsidiary borrowed a $60.0 million term loan, secured by, and repaid with proceeds from, (i) royalties from the Zai Collaboration Agreement, and such royalties, or the Royalty Interest, and (ii) a revenue interest based on the Company’s U.S. sales of NUZYRA in an initial amount of two and a half percent (2.5%), which amount may adjust under certain circumstances up to five percent (5%), of the Company’s net U.S. sales, subject to an annual cap of $10.0 million, which may adjust under certain circumstances to $12.0 million, or the Revenue Interest. Under the R-Bridge Loan Agreement, the outstanding principal balance will bear interest at an annual rate of 7.0%, increasing to an annual rate of 10% during the continuance of any event of default. Payments of the obligations outstanding under the R-Bridge Loan Agreement are made quarterly out of the Royalty Interest payments and Revenue Interest payments received by the Subsidiary during such quarter, or the Collection Amount. On each payment date, after payment of certain expenses, the Collection Amount shall be applied first to accrued interest, with any excess up to $15.0 million per annum applied to repay principal until the balance is fully repaid, and any shortfalls being capitalized and added to the principal balance of the loan. Amounts in excess of the $15.0 million annual cap shall be shared between the Company and the R-Bridge Lender based on a formula set out in the R-Bridge Loan Agreement. Following repayment in full of the loan, the first $15.0 million per annum in Collection Amount shall be paid to the Company and any amounts in excess shall be shared between the Company and the R-Bridge Lender based on a formula set out in the R-Bridge Loan Agreement. Prior to the eighth (8th) anniversary of the Closing Date, the R-Bridge Loan Agreement will automatically terminate once the Subsidiary has paid to the R-Bridge Lender, in the form of regularly scheduled payments or as a voluntary prepayment, a capped amount of $114.0 million, less principal, interest and certain fee payments through the date of such prepayment, or the Capped Amount. From and after the eighth (8th) anniversary of the Closing Date, the Revenue Interest can be terminated by payment of the Capped Amount, but the Royalty Interest payments shall continue until maturity of the R-Bridge Loan Agreement on December 31, 2032, at which time, the outstanding principal amount of the loan, if any, together with any accrued and unpaid interest, and all other obligations then outstanding, shall be due and payable in cash by the Subsidiary. The Company’s subsidiary, PRTK SPV1 LLC, a Delaware limited liability company and owner of the Subsidiary’s capital stock, has entered into a Pledge and Security Agreement in favor of the R-Bridge Lender, pursuant to which the Subsidiary’s obligations under the R-Bridge Loan Agreement are secured by PRTK SPV1 LLC’s pledge of all of the Subsidiary’s capital stock. The R-Bridge Loan Agreement contains certain customary affirmative covenants, including those relating to: use of proceeds; maintenance of books and records; financial reporting and notification; compliance with laws; and protection of Company intellectual property. The R-Bridge Loan Agreement also contains certain customary negative covenants, barring the Subsidiary from: certain fundamental transactions; issuing dividends and distributions; incurring additional indebtedness outside of the ordinary course of business; engaging in any business activity other than related to the Zai Collaboration Agreement; and permitting any additional liens on the collateral provided to the R-Bridge Lender under the R-Bridge Loan Agreement. As of June 30, 2023, the Company was in compliance with all covenants under the R-Bridge Loan Agreement. An ancillary agreement executed by the Company and the Subsidiary in respect of the Revenue Interest, contains negative covenants applicable to the Company, including restrictions on the sale or transfer of our assets related to NUZYRA and giving rise to the Revenue Interest, each subject to the exceptions set forth therein. The R-Bridge Loan Agreement contains customary defined events of default, upon which any outstanding principal, unpaid interest, and other obligations of the Subsidiary, shall be immediately due and payable by the Subsidiary. These include: failure to pay any principal or interest when due; failure to pay the Capped Amount when due following a non-qualified change of control of the Company, any uncured breach of a representation, warranty or covenant; any uncured failure to perform or observe covenants; any uncured breach of our representations, warranties or covenants under an ancillary agreement executed by the Company and the Subsidiary in respect of the Royalty Interest; any termination of the Zai Collaboration Agreement; and certain bankruptcy or insolvency events. No events of default had occurred under the R-Bridge Loan Agreement through June 30, 2023. The Company raised approximately $58.3 million in net proceeds in connection with the R-Bridge Loan Agreement, comprised of the $60.0 million term loan funded at execution, net of $1.1 million in lender fees accounted for as debt discount and $0.6 million in direct and incremental third-party expenses accounted for as debt issuance costs. The net proceeds of the term loan, together with cash on hand, was used to prepay in full all obligations outstanding under our loan arrangement with Hercules Capital, Inc. The accounting for the R-Bridge Loan Agreement requires the Company to make certain estimates and assumptions, particularly about future royalties under the Zai Collaboration Agreement and sales of NUZYRA in the U.S. Such estimates and assumptions are utilized in determining the expected repayment term, amortization period of the debt discount and issuance costs, accretion of interest expense and classification between current and long-term portions of amounts outstanding. The Company amortizes the debt discount and issuance costs to interest expense over the expected term of the arrangement using the interest method based on projected cash flows. Similarly, the Company classifies as current debt for the R-Bridge Loan Agreement, amounts that are expected to be repaid during the succeeding twelve months after the reporting period end. However, the repayment of amounts due under the R-Bridge Loan Agreement is variable because the cash flows to be utilized for periodic payments is a function of amounts received by the Company with respect to the Royalty Interest and the Revenue Interest. Accordingly, the estimates of the magnitude and timing of amounts to be available for debt service are subject to significant variability and thus, subject to significant uncertainty. Therefore, these estimates and assumptions are likely to change, which may result in future adjustments to the portion of the debt that is classified as a current liability, the amortization of debt discount and issuance costs and the accretion of interest expense. The amount of principal to be repaid in each of the five succeeding years is not fixed and determinable. Other amounts that may become due and payable under the R-Bridge Loan Agreement, including amounts shared between the parties with respect to cash flows received in excess of pre-defined thresholds, are recognized as additional interest expense when they become probable and estimable. The following table summarizes the impact of the R-Bridge Loan Agreement on the Company’s condensed consolidated balance sheets at June 30, 2023 and December 31, 2022 (in thousands): June 30, December 31, Principal debt including paid-in-kind interest $ 58,960 $ 59,806 Unamortized debt discount and issuance costs (1,071) (1,205) Carrying value $ 57,889 $ 58,601 In accordance with the terms of the R-Bridge Loan Agreement, the Company repaid approximately $0.8 million of the outstanding principal balance during the six months ended June 30, 2023, comprised of the excess of the Collection Amount over accrued interest on the loan for the six months ended June 30, 2023. The Company recognized coupon interest expense of $2.1 million and $2.2 million, and an insignificant amount of amortization expense on debt issuance costs, on the R-Bridge Loan Agreement for the six months ended June 30, 2023 and June 30, 2022, respectively. The Company recognized coupon interest expense of $1.1 million, and an insignificant amount of amortization expense on debt issuance costs, on the R-Bridge Loan Agreement for each of the three months ended June 30, 2023 and June 30, 2022. Royalty-Backed Loan Agreement On February 25, 2019, the Company, through its wholly-owned subsidiary Paratek Royalty Corporation, or the Subsidiary, entered into a royalty-backed loan agreement, or the Royalty-Backed Loan Agreement, with Healthcare Royalty Partners III, L.P., or HCRP. Pursuant to the terms of the Royalty-Backed Loan Agreement, upon the satisfaction of the conditions precedent set forth therein, the Subsidiary borrowed a $32.5 million loan, which was secured by, and will be repaid based upon, royalties from the Almirall Collaboration Agreement. On May 1, 2019, the Company received $27.8 million, net of $0.5 million lender discount, $0.2 million in lender expenses incurred, and $4.0 million that was deposited into an interest reserve account. The Company also paid $1.2 million in other lender fees related to the Royalty-Backed Loan Agreement. Under the Royalty-Backed Loan Agreement, the outstanding principal balance will bear interest at an annual rate of 12.0%. Payments of interest under the Royalty-Backed Loan Agreement are made quarterly out of the Almirall Collaboration Agreement royalty payments received since the immediately preceding payment date. On each interest payment date, any royalty payments in excess of accrued interest on the loan will be used to repay the principal of the loan until the balance is fully repaid and any royalty shortfalls will be capitalized and added to the principal balance of the loan. In addition, the Subsidiary will make up-front payments to HCRP of (i) a 1.5% fee and (ii) up to $300,000 for HCRP’s expenses. The Royalty-Backed Loan Agreement matures on May 1, 2029, at which time, if not earlier repaid in full, the outstanding principal amount of the loan, together with any accrued and unpaid interest, and all other obligations then outstanding, shall be due and payable in cash. The Company has entered into a Pledge and Security Agreement in favor of HCRP, pursuant to which the Subsidiary’s obligations under the Royalty-Backed Loan Agreement are secured by a pledge of all of the Company’s holdings of the Subsidiary’s capital stock. The Royalty-Backed Loan Agreement contains certain customary affirmative covenants, including those relating to: use of proceeds; maintenance of books and records; financial reporting and notification; compliance with laws; and protection of Company intellectual property. The Royalty-Backed Loan Agreement also contains certain customary negative covenants, barring the Subsidiary from: certain fundamental transactions; issuing dividends and distributions; incurring additional indebtedness outside of the ordinary course of business; engaging in any business activity other than related to the Almirall Collaboration Agreement; and permitting any additional liens on the collateral provided to HCRP under the Royalty-Backed Loan Agreement. The Royalty-Backed Loan Agreement contains customary defined events of default, upon which any outstanding principal and unpaid interest shall be immediately due and payable. These include: failure to pay any principal or interest when due; any uncured breach of a representation, warranty or covenant; any uncured failure to perform or observe covenants; any uncured cross default under a material contract; any uncured breach of the Company’s representations, warranties or covenants under its Contribution and Servicing Agreement with the Subsidiary; any termination of the Almirall Collaboration Agreement; and certain bankruptcy or insolvency events. The following table summarizes the impact of the Royalty-Backed Loan Agreement on the Company’s condensed consolidated balance sheets at June 30, 2023 and December 31, 2022 (in thousands): June 30, December 31, Principal debt including paid-in-kind interest $ 37,849 $ 36,388 Unamortized debt issuance costs (1,453) (1,532) Carrying value $ 36,396 $ 34,856 During the six months ended June 30, 2023, $1.5 million of paid-in-kind interest was capitalized and added to the principal balance of the loan, which represents the shortfall between the interest owed, and the Almirall Collaboration Agreement royalty payments received. The Company recognized coupon interest expense of $2.2 million and $2.0 million for the six months ended June 30, 2023 and June 30, 2022, respectively, and an insignificant amount of amortization expense on the debt issuance costs on the Royalty-Backed Loan Agreement for each of the six months ended June 30, 2023 and June 30, 2022. The Company recognized coupon interest expense of $1.1 million and $1.0 million, for the three months ended June 30, 2023 and June 30, 2022, respectively, and an insignificant amount of amortization expense on debt issuance costs, on the Royalty-Backed Loan Agreement for each of the three months ended June 30, 2023 and June 30, 2022. Short-Term Debt Convertible Senior Subordinated Notes On April 18, 2018, the Company entered into a Purchase Agreement, or the Purchase Agreement, with several initial purchasers, or the Initial Purchasers, for whom Merrill Lynch, Pierce, Fenner & Smith Incorporated and Leerink Partners LLC acted as representatives, relating to the sale of $135.0 million aggregate principal amount of 4.75% Convertible Senior Subordinated Notes due 2024, or the Notes, to the Initial Purchasers. The Company also granted the Initial Purchasers an option to purchase up to an additional $25.0 million aggregate principal amount of Notes, which was exercised in full on April 20, 2018. The Purchase Agreement includes customary representations, warranties and covenants. Under the terms of the Purchase Agreement, the Company agreed to indemnify the Initial Purchasers against certain liabilities. In addition, J. Wood Capital Advisors LLC, the Company’s financial advisor, purchased $5.0 million aggregate principal amount of Notes in a separate, concurrent private placement on the same terms as other investors. The Notes were issued by the Company on April 23, 2018, pursuant to an Indenture, dated as of such date, or the Indenture, between the Company and U.S. Bank National Association, as trustee, or the Trustee. The Notes bear cash interest at the annual rate of 4.75%, payable on November 1 and May 1 of each year, beginning on November 1, 2018, and mature on May 1, 2024 unless earlier repurchased, redeemed or converted. The Company will settle conversions of the Notes through delivery of shares of common stock of the Company, in accordance with the terms of the Indenture. The initial conversion rate for the Notes is 62.8931 shares of common stock (subject to adjustment as provided for in the Indenture) per $1,000 principal amount of the Notes, which is equal to an initial conversion price of approximately $15.90 per share, representing a conversion premium of approximately 20% above the closing price of the common stock of $13.25 per share on April 18, 2018. Holders of the Notes may convert all or any portion of their Notes, in multiples of $1,000 principal amount, at their option at any time prior to the close of business on the second scheduled trading day immediately preceding the stated maturity date. The Company may redeem for cash all or part of the Notes, at its option, on or after May 6, 2021, if the last reported sale price of the Company’s common stock has been at least 130% of the conversion price then in effect for at least 20 trading days (whether or not consecutive) during any 30 consecutive trading day period (including the last trading day of such period) ending on, and including, the trading day immediately preceding the date on which the Company provides notice of redemption at a redemption price equal to 100% of the principal amount of the Notes to be redeemed, plus accrued and unpaid interest to, but excluding, the redemption date. If the Company experiences a fundamental change, as described in the Indenture, prior to the maturity date of the Notes, holders of the Notes will, subject to specified conditions, have the right, at their option, to require the Company to repurchase for cash all or a portion of their Notes at a repurchase price equal to 100% of the principal amount of the Notes to be repurchased, plus accrued and unpaid interest, if any, to, but not including, the fundamental change repurchase date. In addition, following certain corporate events that occur prior to the maturity date of the Notes and following a notice of redemption of the Notes, the Company will increase the conversion rate for a holder who elects to convert its Notes in connection with such corporate event or redemption. The Indenture provides for customary events of default. In the case of an event of default with respect to the Notes arising from specified events of bankruptcy or insolvency, all outstanding Notes will become due and payable immediately without further action or notice. If any other event of default with respect to the Notes under the Indenture occurs or is continuing, the Trustee or holders of at least 25% in aggregate principal amount of the then outstanding Notes may declare the principal amount of the Notes to be immediately due and payable. After deducting costs incurred of $6.0 million, the Company raised net proceeds from the issuance of long-term convertible debt of $159.0 million in April 2018. All costs were deferred and are being amortized over the life of the Notes at an effective interest rate of 5.47% and recorded as additional interest expense. The Company evaluated the conversion feature and determined it was not within the scope of ASC 815 and therefore is not required to be accounted for separately. The Company concluded that the embedded conversion option is not subject to separate accounting pursuant to either the cash conversion guidance or the beneficial conversion feature guidance. Under the general conversion guidance in ASC 470, Debt , all of the proceeds received from the Notes was recorded as a liability on the condensed consolidated balance sheet. The following table summarizes the impact of the Notes on the Company’s condensed consolidated balance sheets at June 30, 2023 and December 31, 2022 (in thousands): June 30, December 31, Principal debt $ 165,000 $ 165,000 Unamortized debt issuance costs (958) (1,511) Carrying value $ 164,042 $ 163,489 The Company recognized coupon interest expense of $3.9 million for each of the six months ended June 30, 2023 and June 30, 2022, and amortization expense on the debt issuance costs of $0.6 million and $0.5 million on the Notes for the six months ended June 30, 2023 and June 30, 2022, respectively. The Company recognized coupon interest expense of $2.0 million and amortization expense on the debt issuance costs of $0.3 million for each of the three months ended June 30, 2023 and June 30, 2022. Debt issuance costs are presented on the consolidated balance sheet as a direct deduction from the related debt liability rather than capitalized as an asset in accordance with ASU No. 2015-03, Interest - Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs . |

Leases | Leases Operating Leases The Company leases its Boston, Massachusetts and King of Prussia, Pennsylvania office spaces under non-cancelable operating leases expiring in 2023 and 2026, respectively. The Company executed an amendment to the existing lease agreement on its Boston office space in April 2021. The amended lease agreement released 8,104 rentable square feet of office space and extended the lease term for the remaining 4,153 rentable square feet of office space through August 2023 for an additional commitment of $0.4 million. In accordance with the amendment, a cash-collateralized irrevocable standby letter of credit for the lease was reduced to an insignificant amount as of June 30, 2023. In July 2023, the Company extended its lease agreement on its Boston office space on a month-to-month basis, commencing on September 1, 2023. The Company executed an amended lease agreement on its King of Prussia office space in November 2022.

Income Tax Disclosure [Abstract] | |
Income Taxes | Income Taxes The Company recorded an insignificant provision for income taxes for the three and six months ended June 30, 2023 and no provision for income taxes for the three and six months ended June 30, 2022. Deferred tax assets and deferred tax liabilities are recognized based on temporary differences between the financial reporting and tax bases of assets and liabilities using statutory rates. Management of the Company has evaluated the positive and negative evidence bearing upon the realizability of its deferred tax assets, which are comprised principally of net operating loss carryforwards and research and development credits. Under the applicable accounting standards, management has considered the Company’s history of losses and concluded that it is more likely than not that the Company will not recognize the benefits of federal and state deferred tax assets. Accordingly, a full valuation allowance has been established against the Company’s otherwise recognizable net deferred tax assets. |

Commitments and Contingencies | Commitments and Contingencies In the ordinary course of business, the Company is from time to time involved in lawsuits, claims, investigations, proceedings, and threats of litigation relating to intellectual property, commercial arrangements, employment and other matters. While the outcome of these proceedings and claims cannot be predicted with certainty, as of June 30, 2023, the Company was not party to any legal or arbitration proceedings that may have, or have had in the recent past, significant effects on the Company’s financial position. No governmental proceedings are pending or, to the Company’s knowledge, contemplated against the Company. The Company is not a party to any material proceedings in which any director, member of executive management or affiliate of the Company is either a party adverse to the Company or the Company’s subsidiaries or has a material interest adverse to the Company or the Company’s subsidiaries. In July 2021, the Company entered into a supply agreement with CARBOGEN AMCIS AG, or Carbogen, that provides for the terms and conditions under which Carbogen will manufacture and supply to the Company the active pharmaceutical ingredient for the Company’s omadacycline product in bulk quantities, or the Carbogen Product. Under this agreement, the Company is responsible for the cost and supply of crude omadacycline that Carbogen requires to manufacture the Carbogen Product and perform related services. The Company is obligated to initially pay Carbogen an amount in the high six-digit U.S. dollar range per batch of Carbogen Product that the Company orders, and the price may be adjusted in accordance with the terms of the agreement. The Company may also request that Carbogen perform certain services related to the Carbogen Product, for which the Company will pay reasonable compensation to Carbogen. The agreement will remain in effect for a fixed initial term. If neither party has provided notice of its intent to terminate the agreement prior to the end of the initial term, then the Agreement will automatically be extended for a fixed period of time. The agreement may be terminated under certain circumstances, including by either party delivering notice of termination following the initial term, or by either party due to a material uncured breach by the other party or the other party’s insolvency. In November 2016, the Company entered into a manufacturing and services agreement, or MSA, with CIPAN, which was later amended and restated in April 2018, and further amended in February 2019, December 2019, July 2020, December 2020, January 2022, and February 2023, collectively, the CIPAN Agreements. The CIPAN Agreements provide the terms and conditions under which CIPAN will manufacture and supply to the Company increased quantities of minocycline starting material and crude omadacycline, or the CIPAN Products, for purification into omadacycline and, subsequently, for use in the Company’s products that contain omadacycline tosylate as the active pharmaceutical ingredient. Additionally, the CIPAN Agreements included an investment by the Company in a new facility area to increase the manufacturing capacity for production of crude omadacycline. The Company was required to make advance payments to CIPAN upon completion of certain milestones within the CIPAN Agreements. The term of the CIPAN Agreements will continue throughout the term that the Company receives benefit from the new facility area. The Company may renew the CIPAN Agreements for additional periods and can terminate the CIPAN Agreements at any time by delivery, within a certain time period, of prior written notice to CIPAN. Following the first renewal term, CIPAN may terminate the MSA in its entirety by delivery, within a certain time period, of prior written notice to the Company. Under the CIPAN Agreements, the Company will purchase product in batches from CIPAN in quantities to be set forth on purchase orders submitted to CIPAN, within a certain time period, prior to the requested date of delivery. The Company will provide CIPAN with a rolling forecast with a best estimate of the quantities that will be ordered each month. |

Accounting Changes and Error Corrections [Abstract] | |
Recent Accounting Pronouncements | Recent Accounting Pronouncements From time to time, new accounting pronouncements are issued by the FASB or other standard setting bodies and adopted by the Company as of the specified effective date. Unless otherwise discussed, the Company believes that the impact of recently issued standards that are not yet effective will not have a material impact on its financial position or results of operations upon adoption. In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments , or ASU 2016-13. The FASB subsequently issued amendments to ASU 2016-13, which have the same effective date and transition date of January 1, 2023. These standards require that credit losses be reported using an expected losses model rather than the incurred losses model that is currently used, and establishes additional disclosures related to credit risks. For available-for-sale debt securities with unrealized losses, these standards now require allowances to be recorded instead of reducing the amortized cost of the investment. These standards limit the amount of credit losses to be recognized for available-for-sale debt securities to the amount by which carrying value exceeds fair value and requires the reversal of previously recognized credit losses if fair value increases. Based on the composition of our investment portfolio, accounts receivable and other financial assets, current market conditions and historical credit loss activity, the adoption of these standards does not have a material effect on the Company’s consolidated balance sheet, consolidated statements of operation and comprehensive loss and related disclosures. |
