Organization, Consolidation and Presentation of Financial Statements [Abstract] | |
The Company and Basis of Presentation | The Company and Basis of Presentation Insmed is a global biopharmaceutical company on a mission to transform the lives of patients with serious and rare diseases. The Company's first commercial product, ARIKAYCE (amikacin liposome inhalation suspension), received accelerated approval in the United States (US) on September 28, 2018 for the treatment of Mycobacterium avium complex (MAC) lung disease as part of a combination antibacterial drug regimen for adult patients with limited or no alternative treatment options. MAC lung disease is a rare and often chronic infection that can cause irreversible lung damage and can be fatal. The Company's clinical-stage pipeline includes INS1007 and INS1009. INS1007 is a novel oral, reversible inhibitor of dipeptidyl peptidase 1 (DPP1) with therapeutic potential in non-cystic fibrosis (non-CF) bronchiectasis and other inflammatory diseases. INS1009 is an inhaled formulation of a treprostinil prodrug that may offer a differentiated product profile for rare pulmonary disorders, including pulmonary arterial hypertension (PAH). The Company was incorporated in the Commonwealth of Virginia on November 29, 1999 and its principal executive offices are in Bridgewater, New Jersey. The Company has legal entities in the US, Ireland, Germany, France, the United Kingdom (UK), the Netherlands, Bermuda and Japan. The accompanying unaudited interim consolidated financial statements have been prepared pursuant to the rules and regulations for reporting on Form 10-Q. Accordingly, certain information and disclosures required by accounting principles generally accepted in the US for complete consolidated financial statements are not included herein. The unaudited interim consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2018 . The results of operations of any interim period are not necessarily indicative of the results of operations for the full year. The unaudited interim consolidated financial information presented herein reflects all normal adjustments that are, in the opinion of management, necessary for a fair statement of the financial position, results of operations and cash flows for the periods presented. The Company had $420.2 million in cash and cash equivalents as of March 31, 2019 and reported a net loss of $74.2 million for the three months ended March 31, 2019 . Historically, the Company has funded its operations through public offerings of equity securities and debt financings. The Company commenced commercial shipments of ARIKAYCE in October 2018. The Company expects to continue to incur operating losses both in our US and certain international entities while funding research and development (R&D) activities for ARIKAYCE and our other pipeline programs, continuing commercial launch activities for ARIKAYCE in the US, continuing to invest in pre-commercial and regulatory activities for ARIKAYCE in Europe and Japan, and funding other general and administrative activities. The Company expects its future cash requirements to be substantial, and the Company may need to raise additional capital to fund operations, including the commercialization of ARIKAYCE and additional clinical trials related to ARIKAYCE, to develop INS1007 and INS1009 and to develop, acquire, in-license or co-promote other products or product candidates that address orphan or rare diseases. The source, timing and availability of any future financing or other transaction will depend principally upon continued progress in the Company’s commercial, regulatory and development activities. Any equity or debt financing will also be contingent upon equity and debt market conditions and interest rates at the time. If the Company is unable to obtain sufficient additional funds when required, the Company may be forced to delay, restrict or eliminate all or a portion of its development programs or commercialization efforts. |

Accounting Policies [Abstract] | |
Summary of Significant Accounting Policies | Summary of Significant Accounting Policies The following are the required interim disclosure updates to the Company's significant accounting policies described in Note 2 of the notes to the consolidated financial statements in the Company’s Annual Report on Form 10-K for the year ended December 31, 2018 : Fair Value Measurements - The Company categorizes its financial assets and liabilities measured and reported at fair value in the financial statements on a recurring basis based upon the level of judgment associated with the inputs used to measure their fair value. Hierarchical levels, which are directly related to the amount of subjectivity associated with the inputs used to determine the fair value of financial assets and liabilities, are as follows: • Level 1 — Inputs are unadjusted, quoted prices in active markets for identical assets or liabilities at the measurement date. • Level 2 — Inputs (other than quoted prices included in Level 1) are either directly or indirectly observable for the assets or liability through correlation with market data at the measurement date and for the duration of the instrument’s anticipated life. • Level 3 — Inputs reflect management’s best estimate of what market participants would use in pricing the asset or liability at the measurement date. Consideration is given to the risk inherent in the valuation technique and the risk inherent in the inputs to the model. Each major category of financial assets and liabilities measured at fair value on a recurring basis is categorized based upon the lowest level of significant input to the valuations. The fair value hierarchy also requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. Financial instruments in Level 1 generally include US treasuries and mutual funds listed in active markets. The Company’s only financial assets and liabilities which were measured at fair value as of March 31, 2019 and December 31, 2018 were Level 1 assets comprised of cash and cash equivalents. The Company's cash and cash equivalents permit daily redemption and the fair values of these investments are based upon the quoted prices in active markets provided by the holding financial institutions. The following table shows assets and liabilities that are measured at fair value on a recurring basis and their carrying value (in millions): As of March 31, 2019 Fair Value Carrying Value Level 1 Level 2 Level 3 Cash and cash equivalents $ 420.2 $ 420.2 $ — $ — The Company recognizes transfers between levels within the fair value hierarchy, if any, at the end of each quarter. There were no transfers in or out of Level 1, Level 2 or Level 3 during the three months ended March 31, 2019 and 2018 , respectively. As of March 31, 2019 and December 31, 2018 , the Company held no securities that were in an unrealized gain or loss position. The Company reviews the status of each security quarterly to determine whether an other-than-temporary impairment has occurred. In making its determination, the Company considers a number of factors, including: (1) the significance of the decline; (2) whether the securities were rated below investment grade; (3) how long the securities have been in an unrealized loss position; and (4) the Company’s ability and intent to retain the investment for a sufficient period of time for it to recover. The estimated fair value of the liability component of the 1.75% convertible senior notes due 2025 (the Convertible Notes) (categorized as a Level 2 liability for fair value measurement purposes) as of March 31, 2019 was $438 million , determined using current market factors and the ability of the Company to obtain debt on comparable terms to the Convertible Notes. The $321.3 million carrying value of the Convertibles Notes as of March 31, 2019 excludes the $120.6 million of the unamortized portion of the debt discount. Net Loss Per Share - Basic net loss per share is computed by dividing net loss by the weighted average number of common shares outstanding during the period. Diluted net loss per share is computed by dividing net loss by the weighted average number of common shares and other dilutive securities outstanding during the period. Potentially dilutive securities from stock options, restricted stock units (RSUs) and convertible debt securities would be anti-dilutive as the Company incurred a net loss. Potentially dilutive common shares resulting from the assumed exercise of outstanding stock options and from the assumed conversion of the Convertible Notes are determined based on the treasury stock method. The following table sets forth the reconciliation of the weighted average number of common shares used to compute basic and diluted net loss per share for the three months ended March 31, 2019 and 2018 : Three Months Ended March 31, 2019 2018 (in thousands, except per share amounts) Numerator: Net loss $ (74,153 ) $ (68,524 ) Denominator: Weighted average common shares used in calculation of basic net loss per share: 77,541 76,619 Effect of dilutive securities: Common stock options — — RSUs — — Convertible debt securities — — Weighted average common shares outstanding used in calculation of diluted net loss per share 77,541 76,619 Net loss per share: Basic and diluted $ (0.96 ) $ (0.89 ) The following potentially dilutive securities have been excluded from the computations of diluted weighted average common shares outstanding as of March 31, 2019 and 2018 as their effect would have been anti-dilutive (in thousands): As of March 31, 2019 2018 Stock options to purchase common stock 11,903 9,866 Unvested RSUs 170 234 Convertible debt securities 11,492 11,492 Concentration of Credit Risk —Financial instruments that potentially subject the Company to concentrations of credit risk consist primarily of cash and cash equivalents. The Company places its cash equivalents with high credit-quality financial institutions and may invest its short-term investments in US treasury securities, mutual funds and government agency bonds. The Company has established guidelines relative to credit ratings and maturities that seek to maintain safety and liquidity. The Company is exposed to risks associated with extending credit to customers related to the sale of products. The Company does not require collateral to secure amounts due from its customers. The following table presents the percentage of gross product revenue represented by the Company's three largest customers as of the quarter ended March 31, 2019 . Percentage of Total Gross Product Revenue Customer A 33% Customer B 31% Customer C 16% The Company did not have product revenue prior to US FDA approval of ARIKAYCE in September 2018. The Company relies on third-party manufacturers and suppliers for manufacturing and supply of its products. The inability of the suppliers or manufacturers to fulfill supply requirements of the Company could materially impact future operating results. A change in the relationship with the suppliers or manufacturer, or an adverse change in their business, could materially impact future operating results. Revenue Recognition —In accordance with Accounting Standards Codification (ASC) 606, Revenue from Contracts with Customers, the Company recognizes revenue when a customer obtains control of promised goods or services, in an amount that reflects the consideration the Company expects to receive in exchange for the goods or services provided. To determine revenue recognition for arrangements within the scope of ASC 606, the Company performs the following five steps: (1) identify the contracts with a customer; (2) identify the performance obligations in the contract; (3) determine the transaction price; (4) allocate the transaction price to the performance obligations in the contract; and (5) recognize revenue when or as the entity satisfies a performance obligation. At contract inception, the Company assesses the goods or services promised within each contract and determines those that are performance obligations and assesses whether each promised good or service is distinct. The Company then recognizes as revenue the amount of the transaction price that is allocated to the respective performance obligation when or as the performance obligation is satisfied. For all contracts that fall into the scope of ASC 606, the Company has identified one performance obligation: the sale of ARIKAYCE to its customers. The Company has not incurred or capitalized any incremental costs associated with obtaining contracts with customers. Product revenues consist primarily of sales of ARIKAYCE in the US. Product revenues are recognized once the Company performs and satisfies all five steps mentioned above. In October 2018, the Company began shipping ARIKAYCE to its customers in the US, which include specialty pharmacies and specialty distributors. The Company recognizes revenues for product received by its customers, net of allowances for customer credits, including prompt pay discounts, service fees, estimated rebates, including government rebates such as Medicaid rebates and Medicare Part D coverage gap reimbursements in the US, chargebacks and returns. Customer credits: The Company’s customers are offered various forms of consideration, including service fees and prompt payment discounts. The Company anticipates that its customers will earn prompt payment discounts and, therefore, deducts the full amount of these discounts from total gross product revenues when revenues are recognized. Service fees are also deducted from total gross product revenues as they are earned. Rebates: The Company contracts with Medicaid, other government agencies and various private organizations, or collectively, third-party payors, so that ARIKAYCE will be eligible for purchase by, or partial or full reimbursement from, such third-party payors. The Company estimates the rebates it will provide to third-party payors and deducts these estimated amounts from total gross product revenues at the time the revenues are recognized. Chargebacks: Chargebacks are discounts that occur when certain contracted customers, currently public health service institutions and federal government entities purchasing via the Federal Supply Schedule, purchase directly from the Company's specialty distributor. Contracted customers generally purchase the product at a discounted price and the specialty distributor, in turn, charges back to the Company the difference between the price initially paid by the specialty distributor and the discounted price paid by the contracted customers. The Company estimates the chargebacks it provides to the specialty distributor and deducts these estimated amounts from total gross product revenues at the time the revenues are recognized. Co-payment assistance: Patients who have commercial insurance and meet certain eligibility requirements may receive co-payment assistance. The Company accrues a liability for co-payment assistance based on actual program participation and estimates of program redemption using data provided by a third-party administrator. If any, or all, of the Company’s actual experience vary from the estimates above, the Company may need to adjust prior period accruals, affecting revenue in the period of adjustment. The Company has initiated early access programs (EAPs) in Europe and other countries, some of which may be fully reimbursed. EAPs are intended to make products available on a named patient basis before they are commercially available in accordance with local regulations. Cost of product revenues (excluding amortization of intangible assets) - Prior to FDA approval of ARIKAYCE, the Company expensed all inventory related costs in the period incurred. Inventory used for clinical development purposes is expensed to research and development (R&D) expense when consumed. Cost of product revenues (excluding amortization of intangible assets) consist primarily of direct and indirect costs related to the manufacturing of ARIKAYCE sold, including third-party manufacturing costs, packaging services, freight, allocation of overhead costs, and inventory adjustment charges, in addition to royalty expenses due to PARI Pharma GmbH (PARI). Recently Adopted Accounting Pronouncements - In August 2016, the Financial Accounting Standards Board (FASB) issued Accounting Standard Update (ASU) 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments , which addressed eight specific cash flow issues with the objective of reducing the existing diversity in practice. Among the updates, the standard requires debt extinguishment costs to be classified as cash outflows for financing activities. This standard update became effective as of the first quarter of 2018. As a result of the adoption of the standard, in the first quarter of 2018, the Company reported a $2.2 million loss on extinguishment of debt in the operating activities section of its consolidated statement of cash flows. The Company had no material debt extinguishment costs prior to the first quarter of 2018. The impact of adopting this standard was not material to the Company. In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842) in order to increase transparency and comparability among organizations by recognizing lease assets and lease liabilities on the balance sheet for those leases classified as operating leases under previous generally accepted accounting principles. ASU 2016-02 requires a lessee to recognize a liability to make lease payments (the lease liability) and a right-of-use asset representing its right to use the underlying asset for the lease term on the balance sheet. ASU 2016-02 is effective for fiscal years beginning after December 15, 2018 (including interim periods within those periods) and early adoption was permitted. In August 2018, the FASB issued ASU 2018-11, Targeted Improvements to ASC 842 , which provided a transition option in which an entity would initially apply ASU 2016-02 at the adoption date and recognize a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption. The Company used the new transition option and the package of practical expedients that allowed it to not reassess: (1) whether any expired or existing contracts are or contain leases; (2) lease classification for any expired or existing leases; and (3) initial direct costs for any expired or existing leases. The Company also used the practical expedient that allows it to treat the lease and non-lease components of its leases as a single component. The Company adopted ASU 2016-02 effective January 1, 2019. The impact of the adoption of ASU 2016-02 on the consolidated balance sheet was $47.4 million . Refer to Note 6 - Leases for additional details about the Company's lease portfolio, including Topic 842 required disclosures. New Accounting Pronouncements (Not Yet Adopted) |

Leases [Abstract] | |
Leases | Leases The Company's lease portfolio consists primarily of office space, manufacturing facilities and fleet vehicles. Currently, all of the Company's leases that have commenced are classified as operating leases. The terms of its lease agreements that have commenced range from less than one year to seven years . In its assessment of the term of each such lease, the Company has not included any options to extend or terminate the lease due to the absence of economic incentives in its lease agreements. As permitted by the practical expedient in ASU 2016-02, leases that qualify for treatment as a short-term lease are expensed as incurred. These short-term leases are not material to the Company's financial position. Furthermore, the Company has elected the practical expedient to not separate lease and non-lease components for all classes of underlying assets. The Company's leases do not contain residual value guarantees and it does not sublease any of its leased assets. The Company outsources its manufacturing operations to CMOs. Upon review of the agreements with its CMOs, the Company determined that these contracts contain embedded leases for dedicated manufacturing facilities. The Company obtains substantially all of the economic benefits from the use of the manufacturing facilities, has the right to direct how and for what purpose the facility is used throughout the period of use, and the supplier does not have the right to change the operating instructions of the facility. The right-of-use asset and corresponding lease liability associated with the manufacturing facilities is the sum of the minimum guarantees over the life of the production contracts. In order to determine the appropriate discount rate for each lease, the Company determined its public credit rating and constructed debt yield curves. The debt yield curves were adjusted to reflect a collateral borrowing and differences in foreign currencies, where applicable, as well as to match the term of each lease. The table below summarizes the Company's total lease costs included in its consolidated financial statements, as well as other required quantitative disclosures (in thousands). Three Months Ended March 31, 2019 Lease cost Operating lease cost $ 3,078 Total lease cost $ 3,078 Other information: Cash paid for amounts included in the measurement of lease liabilities: Operating cash flows for operating leases $ 3,134 Right-of-use assets obtained in exchange for new operating lease liabilities $ 47,396 Weighted average remaining lease term - operating leases (years) 5.5 Weighted average discount rate - operating leases 7.3 % The table below presents the maturity of lease liabilities on an annual basis for the remaining years of the Company's commenced lease agreements (in thousands).

In September 2018, the Company entered into an agreement to lease its new corporate headquarters in Bridgewater, NJ for which the initial lease term expires in June 2030. Upon commencement of the lease, which is anticipated to occur in the second half of 2019, the lease will be accounted for as a finance lease. Additionally, in October 2017, the Company entered into certain agreements with Patheon UK Limited (Patheon) related to increasing its long-term production capacity for ARIKAYCE commercial inventory. Similar to the CMO arrangements previously described, the Company has determined that this agreement with Patheon contains an embedded lease for the manufacturing facility and the specialized equipment contained therein. Costs incurred by the Company related to the agreement of $7.1 million |

Debt Disclosure [Abstract] | |
Debt | Debt In January 2018, the Company completed an underwritten public offering of the Convertible Notes, in which the Company sold $450.0 million aggregate principal amount of Convertible Notes, including the exercise in full of the underwriters' option to purchase additional Convertible Notes of $50.0 million . The Company's net proceeds from the offering, after deducting underwriting discounts and commissions and other offering expenses of $14.2 million , were approximately $435.8 million . The Convertible Notes bear interest payable semiannually in arrears on January 15 and July 15 of each year, beginning on July 15, 2018. The Convertible Notes mature on January 15, 2025, unless earlier converted, redeemed, or repurchased. On or after October 15, 2024, until the close of business on the second scheduled trading day immediately preceding January 15, 2025, holders may convert their Convertible Notes at any time. Upon conversion, holders may receive cash, shares of the Company's common stock or a combination of cash and shares of the Company's common stock, at the Company's option. The initial conversion rate is 25.5384 shares of common stock per $1,000 principal amount of Convertible Notes (equivalent to an initial conversion price of approximately $39.16 per share of common stock). The conversion rate will be subject to adjustment in some events but will not be adjusted for any accrued and unpaid interest. Holders may convert their Convertible Notes prior to October 15, 2024, only under the following circumstances, subject to the conditions set forth in an indenture, dated as of January 26, 2018, between the Company and Wells Fargo Bank, National Association (Wells Fargo), as trustee, as supplemented by the first supplemental indenture, dated January 26, 2018, between the Company and Wells Fargo (as supplemented, the Indenture): (i) during the five business day period immediately after any five consecutive trading day period (the measurement period) in which the trading price per $1,000 principal amount of convertible notes, as determined following a request by a holder of the convertible notes, for each trading day of the measurement period was less than 98% of the product of the last reported sale price of the common stock and the conversion rate on such trading day, (ii) the Company elects to distribute to all or substantially all holders of the common stock (a) any rights, options or warrants (other than in connection with a stockholder rights plan for so long as the rights issued under such plan have not detached from the associated shares of common stock) entitling them, for a period of not more than 45 days from the declaration date for such distribution, to subscribe for or purchase shares of common stock at a price per share that is less than the average of the last reported sale prices of the common stock for the 10 consecutive trading day period ending on, and including, the trading day immediately preceding the declaration date for such distribution, or (b) the Company’s assets, debt securities or rights to purchase securities of the Company, which distribution has a per share value, as reasonably determined by the board of directors, exceeding 10% of the last reported sale price of the common stock on the trading day immediately preceding the declaration date for such distribution, (iii) if a transaction or event that constitutes a fundamental change or a make-whole fundamental change occurs, or if the Company is a party to (a) a consolidation, merger, combination, statutory or binding share exchange or similar transaction, pursuant to which the common stock would be converted into, or exchanged for, cash, securities or other property or assets, or (b) any sale, conveyance, lease or other transfer or similar transaction in one transaction or a series of transactions of all or substantially all of the consolidated assets of the Company and its subsidiaries, taken as a whole, all or any portion of the Convertible Notes may be surrendered by a holder for conversion at any time from or after the date that is 30 scheduled trading days prior to the anticipated effective date of the transaction, (iv) if during any calendar quarter commencing after the calendar quarter ending on March 31, 2018 (and only during such calendar quarter), the last reported sale price of the common stock for at least 20 trading days (whether or not consecutive) during the period of 30 consecutive trading days ending on the last trading day of the immediately preceding calendar quarter is greater than or equal to 130% of the conversion price on each applicable trading day, or, (v) if the Company sends a notice of redemption, a holder may surrender all or any portion of its Convertible Notes, to which the notice of redemption relates, for conversion at any time on or after the date the applicable notice of redemption was sent until the close of business on (a) the second business day immediately preceding the related redemption date or (b) if the Company fails to pay the redemption price on the redemption date as specified in such notice of redemption, such later date on which the redemption price is paid. The Convertible Notes can be settled in cash, common stock, or a combination of cash and common stock at the Company's option, and thus, the Company determined the embedded conversion options in the convertible notes are not required to be separately accounted for as a derivative. However, since the Convertible Notes are within the scope of the accounting guidance for cash convertible instruments, the Company is required to separate the Convertible Notes into liability and equity components. The carrying amount of the liability component as of the date of issuance was calculated by measuring the fair value of a similar liability that did not have an associated equity component. The fair value was based on data from readily available pricing sources which utilize market observable inputs and other characteristics for similar types of instruments. The carrying amount of the equity component representing the embedded conversion option was determined by deducting the fair value of the liability component from the gross proceeds of the Convertible Notes. The excess of the principal amount of the liability component over its carrying amount is amortized to interest expense over the expected life of a similar liability that does not have an associated equity component using the effective interest method. The equity component is not remeasured as long as it continues to meet the conditions for equity classification in the accounting guidance for contracts in an entity’s own equity. The fair value of the liability component of the Convertible Notes on the date of issuance was estimated at $309.1 million using an effective interest rate of 7.6% , and accordingly, the residual equity component on the date of issuance was $140.9 million . The discount is being amortized to interest expense over the term of the Convertible Notes and has a remaining period of approximately 5.79 years . The following table presents the carrying value of the Company’s debt balance (in thousands): March 31, 2019 December 31, 2018 1.75% convertible senior notes due 2025 $ 450,000 $ 450,000 Debt issuance costs, unamortized (8,091 ) (8,440 ) Discount on debt (120,596 ) (125,002 ) Long-term debt, net $ 321,313 $ 316,558 As of March 31, 2019 , future principal repayments of the debt for each of the fiscal years through maturity were as follows (in thousands): Year Ending December 31: 2019 $ — 2020 — 2021 — 2022 — 2023 — 2024 and thereafter 450,000 $ 450,000 In February 2018, the Company used part of the net proceeds from the issuance of the Convertible Notes to pay off its outstanding debt to Hercules Capital (Hercules). The payments to Hercules consisted of $55.0 million for the principal amount and an additional $3.2 million in back-end fees, outstanding interest, and prepayment penalty fees, which resulted in a $2.2 million loss on extinguishment of debt in the quarter ended March 31, 2018. Interest Expense For the three months ended March 31, 2019 and March 31, 2018 , interest expense related to the Convertible Notes was $6.7 million and $5.6 million , respectively, which includes the contractual interest coupon payable semi-annually in cash, the amortization of the issuance costs, and accretion of debt discount, as described in the table below (in thousands): Three Months Ended March 31, 2019 2018 Contractual interest expense $ 1,971 $ 2,272 Amortization of debt issuance costs 349 299 Accretion of back-end fee on debt — 50 Accretion of debt discount 4,406 3,021 Total interest expense $ 6,726 $ 5,642 |

Income Taxes | Income Taxes The Company’s provision for income taxes was $ 0.2 million and $ 0.0 million for the three months ended March 31, 2019 and March 31, 2018 , respectively. The provision for income taxes in both periods was a result of certain of the Company’s international subsidiaries, which had taxable income during the three months ended March 31, 2019 and 2018 . In jurisdictions where the Company has net losses, there was a full valuation allowance recorded against the Company’s deferred tax assets and therefore no tax benefit was recorded. The Company is subject to US federal and state income taxes and the statute of limitations for tax audit is open for the Company's federal tax returns for the years ended 2014 and later, and is generally open for certain states for the years 2013 and later. The Company has incurred net operating losses since inception, except for the year ended December 31, 2009. Such loss carryforwards would be subject to audit in any tax year in which those losses are utilized, notwithstanding the year of origin. As of March 31, 2019 and December 31, 2018 , the Company had recorded reserves for unrecognized income tax benefits against certain deferred tax assets in the United States. However, given the Company’s valuation allowance position these reserves do not have an impact on the balance sheet as of March 31, 2019 and December 31, 2018 or the income statement for the three months ended March 31, 2019 and March 31, 2018 |

Fair Value Measurements | Fair Value Measurements - The Company categorizes its financial assets and liabilities measured and reported at fair value in the financial statements on a recurring basis based upon the level of judgment associated with the inputs used to measure their fair value. Hierarchical levels, which are directly related to the amount of subjectivity associated with the inputs used to determine the fair value of financial assets and liabilities, are as follows: • Level 1 — Inputs are unadjusted, quoted prices in active markets for identical assets or liabilities at the measurement date. • Level 2 — Inputs (other than quoted prices included in Level 1) are either directly or indirectly observable for the assets or liability through correlation with market data at the measurement date and for the duration of the instrument’s anticipated life. • Level 3 — Inputs reflect management’s best estimate of what market participants would use in pricing the asset or liability at the measurement date. Consideration is given to the risk inherent in the valuation technique and the risk inherent in the inputs to the model. Each major category of financial assets and liabilities measured at fair value on a recurring basis is categorized based upon the lowest level of significant input to the valuations. The fair value hierarchy also requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. Financial instruments in Level 1 generally include US treasuries and mutual funds listed in active markets. The Company’s only financial assets and liabilities which were measured at fair value as of March 31, 2019 and December 31, 2018 were Level 1 assets comprised of cash and cash equivalents. The Company's cash and cash equivalents permit daily redemption and the fair values of these investments are based upon the quoted prices in active markets provided by the holding financial institutions. The following table shows assets and liabilities that are measured at fair value on a recurring basis and their carrying value (in millions): As of March 31, 2019 Fair Value Carrying Value Level 1 Level 2 Level 3 Cash and cash equivalents $ 420.2 $ 420.2 $ — $ — The Company recognizes transfers between levels within the fair value hierarchy, if any, at the end of each quarter. There were no transfers in or out of Level 1, Level 2 or Level 3 during the three months ended March 31, 2019 and 2018 , respectively. As of March 31, 2019 and December 31, 2018 , the Company held no securities that were in an unrealized gain or loss position. The Company reviews the status of each security quarterly to determine whether an other-than-temporary impairment has occurred. In making its determination, the Company considers a number of factors, including: (1) the significance of the decline; (2) whether the securities were rated below investment grade; (3) how long the securities have been in an unrealized loss position; and (4) the Company’s ability and intent to retain the investment for a sufficient period of time for it to recover. |
Net Loss Per Share | Net Loss Per Share - Basic net loss per share is computed by dividing net loss by the weighted average number of common shares outstanding during the period. Diluted net loss per share is computed by dividing net loss by the weighted average number of common shares and other dilutive securities outstanding during the period. Potentially dilutive securities from stock options, restricted stock units (RSUs) and convertible debt securities would be anti-dilutive as the Company incurred a net loss. Potentially dilutive common shares resulting from the assumed exercise of outstanding stock options and from the assumed conversion of the Convertible Notes are determined based on the treasury stock method. The following table sets forth the reconciliation of the weighted average number of common shares used to compute basic and diluted net loss per share for the three months ended March 31, 2019 and 2018 : Three Months Ended March 31, 2019 2018 (in thousands, except per share amounts) Numerator: Net loss $ (74,153 ) $ (68,524 ) Denominator: Weighted average common shares used in calculation of basic net loss per share: 77,541 76,619 Effect of dilutive securities: Common stock options — — RSUs — — Convertible debt securities — — Weighted average common shares outstanding used in calculation of diluted net loss per share 77,541 76,619 Net loss per share: Basic and diluted $ (0.96 ) $ (0.89 ) The following potentially dilutive securities have been excluded from the computations of diluted weighted average common shares outstanding as of March 31, 2019 and 2018 as their effect would have been anti-dilutive (in thousands): As of March 31, 2019 2018 Stock options to purchase common stock 11,903 9,866 Unvested RSUs 170 234 Convertible debt securities 11,492 11,492 |
Concentration of Credit Risk | Concentration of Credit Risk —Financial instruments that potentially subject the Company to concentrations of credit risk consist primarily of cash and cash equivalents. The Company places its cash equivalents with high credit-quality financial institutions and may invest its short-term investments in US treasury securities, mutual funds and government agency bonds. The Company has established guidelines relative to credit ratings and maturities that seek to maintain safety and liquidity. The Company is exposed to risks associated with extending credit to customers related to the sale of products. The Company does not require collateral to secure amounts due from its customers. The following table presents the percentage of gross product revenue represented by the Company's three largest customers as of the quarter ended March 31, 2019 . Percentage of Total Gross Product Revenue Customer A 33% Customer B 31% Customer C 16% |
Revenue Recognition | Revenue Recognition —In accordance with Accounting Standards Codification (ASC) 606, Revenue from Contracts with Customers, the Company recognizes revenue when a customer obtains control of promised goods or services, in an amount that reflects the consideration the Company expects to receive in exchange for the goods or services provided. To determine revenue recognition for arrangements within the scope of ASC 606, the Company performs the following five steps: (1) identify the contracts with a customer; (2) identify the performance obligations in the contract; (3) determine the transaction price; (4) allocate the transaction price to the performance obligations in the contract; and (5) recognize revenue when or as the entity satisfies a performance obligation. At contract inception, the Company assesses the goods or services promised within each contract and determines those that are performance obligations and assesses whether each promised good or service is distinct. The Company then recognizes as revenue the amount of the transaction price that is allocated to the respective performance obligation when or as the performance obligation is satisfied. For all contracts that fall into the scope of ASC 606, the Company has identified one performance obligation: the sale of ARIKAYCE to its customers. The Company has not incurred or capitalized any incremental costs associated with obtaining contracts with customers. Product revenues consist primarily of sales of ARIKAYCE in the US. Product revenues are recognized once the Company performs and satisfies all five steps mentioned above. In October 2018, the Company began shipping ARIKAYCE to its customers in the US, which include specialty pharmacies and specialty distributors. The Company recognizes revenues for product received by its customers, net of allowances for customer credits, including prompt pay discounts, service fees, estimated rebates, including government rebates such as Medicaid rebates and Medicare Part D coverage gap reimbursements in the US, chargebacks and returns. Customer credits: The Company’s customers are offered various forms of consideration, including service fees and prompt payment discounts. The Company anticipates that its customers will earn prompt payment discounts and, therefore, deducts the full amount of these discounts from total gross product revenues when revenues are recognized. Service fees are also deducted from total gross product revenues as they are earned. Rebates: The Company contracts with Medicaid, other government agencies and various private organizations, or collectively, third-party payors, so that ARIKAYCE will be eligible for purchase by, or partial or full reimbursement from, such third-party payors. The Company estimates the rebates it will provide to third-party payors and deducts these estimated amounts from total gross product revenues at the time the revenues are recognized. Chargebacks: Chargebacks are discounts that occur when certain contracted customers, currently public health service institutions and federal government entities purchasing via the Federal Supply Schedule, purchase directly from the Company's specialty distributor. Contracted customers generally purchase the product at a discounted price and the specialty distributor, in turn, charges back to the Company the difference between the price initially paid by the specialty distributor and the discounted price paid by the contracted customers. The Company estimates the chargebacks it provides to the specialty distributor and deducts these estimated amounts from total gross product revenues at the time the revenues are recognized. Co-payment assistance: Patients who have commercial insurance and meet certain eligibility requirements may receive co-payment assistance. The Company accrues a liability for co-payment assistance based on actual program participation and estimates of program redemption using data provided by a third-party administrator. If any, or all, of the Company’s actual experience vary from the estimates above, the Company may need to adjust prior period accruals, affecting revenue in the period of adjustment. |
Cost of product revenues | Cost of product revenues (excluding amortization of intangible assets) - Prior to FDA approval of ARIKAYCE, the Company expensed all inventory related costs in the period incurred. Inventory used for clinical development purposes is expensed to research and development (R&D) expense when consumed. Cost of product revenues (excluding amortization of intangible assets) consist primarily of direct and indirect costs related to the manufacturing of ARIKAYCE sold, including third-party manufacturing costs, packaging services, freight, allocation of overhead costs, and inventory adjustment charges, in addition to royalty expenses due to PARI Pharma GmbH (PARI). |
Recently Adopted Accounting Pronouncements | Recently Adopted Accounting Pronouncements - In August 2016, the Financial Accounting Standards Board (FASB) issued Accounting Standard Update (ASU) 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments , which addressed eight specific cash flow issues with the objective of reducing the existing diversity in practice. Among the updates, the standard requires debt extinguishment costs to be classified as cash outflows for financing activities. This standard update became effective as of the first quarter of 2018. As a result of the adoption of the standard, in the first quarter of 2018, the Company reported a $2.2 million loss on extinguishment of debt in the operating activities section of its consolidated statement of cash flows. The Company had no material debt extinguishment costs prior to the first quarter of 2018. The impact of adopting this standard was not material to the Company. In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842) in order to increase transparency and comparability among organizations by recognizing lease assets and lease liabilities on the balance sheet for those leases classified as operating leases under previous generally accepted accounting principles. ASU 2016-02 requires a lessee to recognize a liability to make lease payments (the lease liability) and a right-of-use asset representing its right to use the underlying asset for the lease term on the balance sheet. ASU 2016-02 is effective for fiscal years beginning after December 15, 2018 (including interim periods within those periods) and early adoption was permitted. In August 2018, the FASB issued ASU 2018-11, Targeted Improvements to ASC 842 , which provided a transition option in which an entity would initially apply ASU 2016-02 at the adoption date and recognize a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption. The Company used the new transition option and the package of practical expedients that allowed it to not reassess: (1) whether any expired or existing contracts are or contain leases; (2) lease classification for any expired or existing leases; and (3) initial direct costs for any expired or existing leases. The Company also used the practical expedient that allows it to treat the lease and non-lease components of its leases as a single component. The Company adopted ASU 2016-02 effective January 1, 2019. The impact of the adoption of ASU 2016-02 on the consolidated balance sheet was $47.4 million . Refer to Note 6 - Leases for additional details about the Company's lease portfolio, including Topic 842 required disclosures. New Accounting Pronouncements (Not Yet Adopted) |
