Organization | 1. Organization Description of business Aptinyx Inc. (the “Company” or “Aptinyx”) was incorporated in Delaware on June 24, 2015, and maintains its headquarters in Evanston, Illinois. Aptinyx is a clinical-stage biopharmaceutical company focused on the discovery, development, and commercialization of novel, proprietary, synthetic small molecules for the treatment of brain and nervous system disorders. Aptinyx has a platform for discovering proprietary compounds that work through a novel mechanism: modulation of N-methyl-D-aspartate receptors (“NMDAr”), which are vital to normal and effective brain and nervous system functions. This mechanism has applicability across numerous nervous system disorders. Liquidity and capital resources On July 1, 2019, the Company entered into a Sales Agreement (the “2019 Sales Agreement”) with Cowen and Company, LLC (“Cowen”) pursuant to which the Company may offer and sell shares of its common stock with an aggregate offering price of up to $50.0 million under an “at the market” offering program (the “2019 ATM Offering”). The 2019 Sales Agreement provides that Cowen will be entitled to a sales commission equal to 3.0% of the gross sales price per share of all shares sold under the 2019 ATM Offering. To date, the Company has sold an aggregate of 5,120,940 shares under the 2019 ATM Offering at a weighted-average price of $3.99 per share for net proceeds of $20.4 million after deducting sales commission and other offering expenses, including 3,629,458 shares for net proceeds of $14.5 million during the six months ended June 30, 2021. On September 15, 2021, the Company entered into a Loan and Security agreement (the “Loan Agreement”) with K2 HealthVentures LLC (“Lender”). The Loan Agreement provides up to $50.0 million principal in term loans, $15.0 million of which was funded at the time the Company entered into the agreement and $10.0 million of which was funded on March 14, 2022. See Note 7 for additional details regarding the Loan Agreement. On September 16, 2021, the Company entered into a Sales Agreement (the “2021 Sales Agreement”) with Cowen pursuant to which the Company may offer and sell shares of its common stock with an aggregate offering price of up to $50.0 million under an “at the market” offering program (the “2021 ATM Offering”) and which supersedes the 2019 Sales Agreement and 2019 ATM Offering. The 2021 Sales Agreement provides that Cowen will be entitled to a sales commission equal to 3.0% of the gross sales price per share of all shares sold under the 2021 ATM Offering. As of the date of these financial statements, no shares of common stock have been issued and sold pursuant to the 2021 Sales Agreement. On March 24, 2022, the Company entered into an amendment to the 2021 Sales Agreement (the “2022 Sales Agreement”) pursuant to which the Company may offer and sell shares of its common stock with an aggregate offering price of up to $75.0 million under an “at the market” offering program (the “2022 ATM Offering”) and which supersedes the 2021 Sales Agreement and 2021 ATM Offering. The 2022 Sales Agreement provides that Cowen will be entitled to a sales commission equal to 3.0% of the gross sales price per share of all shares sold under the 2022 ATM Offering. As of the date of these financial statements, no shares of common stock have been issued and sold pursuant to the 2022 Sales Agreement. As of June 30, 2022, the Company had cash and cash equivalents of $85.3 million, which the Company believes will be sufficient to funds its planned operations for a period of at least twelve months from the date of issuance of these condensed financial statements. |

Summary of significant accounting policies | 2. Basis of presentation The condensed financial statements of the Company included herein have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission (the “SEC”). Certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) have been condensed or omitted from this report, as is permitted by such rules and regulations. The accompanying condensed financial statements reflect all adjustments consisting of normal, recurring adjustments that are necessary for a fair presentation of the financial position, results of operations and cash flows for the interim periods presented. Interim results are not necessarily indicative of results for a full year. Accordingly, these condensed financial statements should be read in conjunction with the financial statements included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2021 (the “Annual Report”) filed with the SEC on March 23, 2022. From time to time, new accounting pronouncements are issued by the Financial Accounting Standards Board (“FASB”), or other standard setting bodies and adopted by the Company as of the specified effective date. Unless otherwise discussed, the impact of recently issued standards that are not yet effective will not have a material impact on the Company’s financial statements upon adoption. Under the Jumpstart Our Business Startups Act of 2012, as amended (the “JOBS Act”), the Company meets the definition of an emerging growth company, and has elected the extended transition period for complying with new or revised accounting standards, which delays the adoption of these accounting standards until they would apply to private companies. Use of estimates The condensed financial statements are prepared in conformity with GAAP. This process requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities as of the date of the financial statements and the reported amounts of expenses during the reporting period. Actual results could differ from those estimates. Risk and uncertainties The Company’s future results of operations involve a number of risks and uncertainties. Factors that could affect the Company’s future operating results and cause actual results to vary materially from expectations include, but are not limited to, uncertainty of: the impact of COVID-19 on future clinical study results, the scope, timing, rate of progress, and expense of the Company’s ongoing as well as any additional preclinical studies, clinical studies, and other research and development activities, clinical study enrollment rate or design, the manufacturing of the Company’s product candidates, significant and changing government regulation, and the timing and receipt of any regulatory approvals. Significant accounting policies The Company’s significant accounting policies are described herein and in Note 3, “Summary of significant accounting policies,” in the Annual Report. There have been no material changes to the significant accounting policies during the six months ended June 30, 2022. Recently issued accounting pronouncement In February 2016, the FASB issued ASU No. 2016-02, Leases fiscal years beginning after December 15, 2022, and early adoption is permitted. The Company anticipates that the adoption of this standard will have an impact on its balance sheet due to the recognition of right-of-use assets and lease liabilities; however, the Company is currently evaluating the impact that the adoption of ASU 2016-02 may have on its condensed financial statements. |

Research collaboration agreement with Allergan | 4. Research collaboration agreement with Allergan On July 24, 2015, the Company entered into a Research Collaboration Agreement (“RCA”) with Naurex Inc., a subsidiary of Allergan plc (“Allergan”), which became a wholly owned subsidiary of AbbVie Inc. in May 2020. The RCA was focused on the research and discovery of small molecules that modulate NMDArs. Under the terms of the agreement, the RCA terminated upon the earlier of (i) 180 days after a predetermined anniversary of the effective date of the RCA and (ii) the date on which Allergan exercised the last of three options to acquire molecules from a pool of eligible compounds, in both cases (clauses (i) and (ii)) subject to potential extension if and as required for the Company to transfer to Allergan information and technology related to compounds that were licensed by Allergan. The jointly funded research activities and option exercise period under the RCA, including the associated payments by Allergan to the Company, came to their contractual conclusions in accordance with the agreement in August 2020 and February 2021, respectively. Under the terms of the agreement, Allergan was to pay the Company $1.0 million for each option exercised by Allergan. On February 23, 2021, Allergan exercised its option to acquire exclusive rights to develop and commercialize AGN-281705 within a predefined set of indications. For the six months ended June 30, 2021, the Company recognized the $1.0 million non-refundable milestone payment within collaboration revenue in the statements of operations as there were no remaining performance obligations associated with the optioned compound. |

Fair value measurements | |
Fair value measurements | 5. Fair value measurements ASC 820, Fair Value Measurement ● Level 1 inputs are quoted prices (unadjusted) in active markets for identical assets or liabilities; ● Level 2 inputs are inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly; and ● Level 3 inputs are unobservable inputs that reflect the Company’s own assumptions about the assumptions market participants would use in pricing the asset or liability. Financial assets and liabilities are classified in their entirety based on the lowest level of input that is significant to the fair value measurement. To the extent that the valuation is based on models or inputs that are less observable or unobservable in the market, the determination of fair value requires more judgment. Accordingly, the degree of judgment exercised by the Company in determining fair value is greatest for instruments categorized in Level 3. A financial instrument’s level within the fair value hierarchy is based on the lowest level of any input that is significant to the fair value measurement. The carrying values reported in the Company’s balance sheets for cash and cash equivalents, restricted cash, accounts receivable, accounts payable, and accrued expenses are reasonable estimates of their fair values due to the short-term nature of these items. Assets and liabilities measured at fair value on a recurring basis as of June 30, 2022, are as follows (in thousands): June 30, 2022 Level 1 Level 2 Level 3 Assets Money market funds, included in cash and cash equivalents $ 76,973 $ 76,973 $ — $ — Money market funds, included in restricted cash 197 197 — — Total Assets $ 77,170 $ 77,170 $ — $ — Liabilities Derivative liability, included in other long-term liabilities $ 16 $ — $ — $ 16 Total Liabilities $ 16 $ — $ — $ 16 Assets measured at fair value on a recurring basis as of December 31, 2021, are as follows (in thousands): December 31, 2021 Level 1 Level 2 Level 3 Assets Money market funds, included in cash and cash equivalents $ 103,859 $ 103,859 $ — $ — Money market funds, included in restricted cash 197 197 — — Total Assets $ 104,056 $ 104,056 $ — $ — Liabilities Derivative liability, included in other long-term liabilities $ 331 $ — $ — $ 331 Total Liabilities $ 331 $ — $ — $ 331 |

The Loan Agreement provides a term loan commitment of $50.0 million in four potential tranches: (i) a $15.0 million term loan facility funded on September 15, 2021 (the “First Tranche Term Loan”); (ii) a $10.0 million term loan facility (the “Second Tranche Term Loan”) funded on March 14, 2022; (iii) a $10.0 million term loan facility (the “Third Tranche Term Loan”) available at the Company’s option between July 1, 2022, and December 1, 2022, subject to the draw of the Second Tranche Term Loan and positive Phase 2 clinical data from NYX-2925 or NYX-458 and progression of another clinical asset; and (iv) a $15.0 million term loan facility (the “Fourth Tranche Term Loan”) available through July 1, 2023, at the Company’s option but subject to review of financial and clinical plans and Lender’s Investment Committee approval. All four of these term loans have a maturity date of September 1, 2025. Borrowings under all four term loan facilities bear interest at a floating per annum rate equal to the greater of (i) 7.95% and (ii) the Prime Rate plus 4.70% . The Company is permitted to make interest-only payments on the First Tranche Term Loan for the first 24 months following the funding date. The interest-only period can be extended by an additional 12 months , subject to the funding of the Second Tranche Term Loan and the funding of the Third Tranche Term Loan. The term of the combined facility will be 48 months , with repayment in monthly installments commencing at the end of the resulting interest-only period as outlined above through the end of the 48-month term. The Company is obligated to pay a final fee equal to 6.45% of the aggregate amount of the term loans funded (“Exit Fee”), to occur upon the earliest of (i) the maturity date, (ii) the acceleration of the term loans, and (iii) the prepayment of the term loans. The Company has the option to prepay all, but not less than all, of the outstanding principal balance of the term loans under the Loan Agreement. If the Company prepays all of the term loans prior to the maturity date, it will pay the Lender a prepayment penalty fee based on a percentage of the outstanding principal balance, equal to 3% if the payment occurs on or before 24 months after the initial funding date, 2% if the prepayment occurs more than 24 months after, but on or before 36 months after the initial funding date, or 1% if the prepayment occurs more than 36 months after the initial funding date. The Company also is obligated to pay the Lender an origination fee of 0.8% of all term loans funded at the time of funding. The Lender may, at its option, elect to convert any portion of no more than $4 million of the then outstanding term loan amount and all accrued and unpaid interest thereon into shares of the Company’s common stock at a conversion price of the lesser of $4.25 per share and the price per share of the common stock in the Company’s next equity offering in which the Company receives at least $20.0 million of gross proceeds . The Company determined that the embedded conversion option is not required to be separated from the term loan. The embedded conversion option meets the derivative accounting scope exception since the embedded conversion option is indexed to the Company’s own common stock and qualifies for classification within stockholders’ equity. The Company’s obligations under the Loan Agreement are secured by a first priority security interest in substantially all of its assets. The Loan Agreement contains customary representations and warranties, and also includes customary events of default, including payment default, breach of covenants, change of control, and material adverse effects. The Loan Agreement restricts certain activities, such as disposing of the Company’s business or certain assets, incurring additional debt or liens or making payments on other debt, making certain investments and declaring dividends, acquiring or merging with another entity, engaging in transactions with affiliates or encumbering intellectual property, among others. There are no financial covenants associated with the Loan Agreement. The Company was in compliance with all non-financial covenants under the Loan Agreement as of June 30, 2022. Upon the occurrence of an event of default, a default interest rate of an additional 5% per annum may be applied to the outstanding loan balances, and the Lender may declare all outstanding obligations immediately due and payable and exercise all of its rights and remedies as set forth in the Loan Agreement and under applicable law. The Company recorded interest expense related to the Loan Agreement of $0.8 million for the three months ended June 30, 2022, and $1.2 million for the six months ended June 30, 2022. Future principal debt payments of the term loans funded as of June 30, 2022, are as follows (in thousands): 2023 $ 2,867 2024 12,167 2025 9,966 2026 — Total principal payments 25,000 Exit Fee 1,613 Total principal payments and Exit Fee 26,613 Less: Unamortized debt discount related to warrants (420) Less: Unamortized debt discount related to Exit Fee (1,335) Less: Unamortized debt issuance costs (360) Term loan, non-current $ 24,498 |

Stock-based compensation expense Non-cash stock-based compensation expense recognized in the accompanying condensed statements of operations relating to stock options, restricted stock awards, and restricted stock units for the three and six months ended June 30, 2022 and 2021, was as follows (in thousands): Three months ended Six months ended June 30, June 30, 2022 2021 2022 2021 Research and development $ 444 $ 676 $ 819 $ 1,413 General and administrative 1,837 1,802 3,812 3,720 Total stock‑based compensation expense $ 2,281 $ 2,478 $ 4,631 $ 5,133 Stock options The table below summarizes activity related to stock options (in thousands, except per share amounts): Weighted ‑ Weighted ‑ average average remaining Aggregate exercise contractual intrinsic Options Shares price term value Outstanding, December 31, 2021 10,713 $ 5.36 8.07 $ 718 Granted 2,286 2.98 Exercised — — Forfeited and canceled (383) 3.97 Outstanding, June 30, 2022 12,616 $ 4.97 7.82 $ 19 Vested and expected to vest at June 30, 2022 12,616 $ 4.97 7.82 $ 19 Exercisable at June 30, 2022 6,282 $ 6.64 6.61 $ 2 During the six months ended June 30, 2022 and 2021, the Company granted 2.3 million and 3.1 million stock options, respectively, and these options had a weighted-average grant-date fair value of $2.28 and $2.73 per share, respectively. The weighted-average grant-date fair value of options was determined using the Black-Scholes option-pricing model. The assumptions used in the Black-Scholes option-pricing model for options granted during the six months ended June 30, 2022, were similar to those as described in the Annual Report, except for the manner in which the expected volatility was determined. The expected volatility for the Company’s options granted during the six months ended June 30, 2022, is based on a weighted-average of the historical volatility of share values of publicly traded companies within the biotechnology industry, which includes the historical volatility of the Company’s stock since the Company’s initial public offering. As of June 30, 2022, there was $14.6 million of total unrecognized stock-based compensation expense related to non-vested stock options, which is expected to be recognized over a weighted-average period of 2.7 years. The options have a ten-year life and generally vest over a period of four years, subject to continuous employment. Restricted stock units In June 2020, the Company issued an aggregate of 205,200 restricted stock units to employees. The restricted stock units issued in 2020 vested ten months from the date of grant. Such shares were not accounted for as outstanding until they vested. Non-cash restricted stock unit award expense recognized in the accompanying condensed statements of operations was $0.0 million and $0.2 million for the three months ended in June 30, 2022 and 2021, respectively, and $0.0 million and $0.8 million for the six months ended June 30, 2022 and 2021, respectively. There were no unvested restricted stock units as of June 30, 2022. |

Warrants and derivative liability | 9. Warrants and derivative liability Warrants On September 15, 2021, the Company entered into the Loan Agreement with the Lender pursuant to which the Lender may provide the Company with term loans in an aggregate principal amount of up to $50.0 million. On September 15, 2021, in connection with the funding of the First Tranche Term Loan, the Company issued a warrant exercisable for 147,600 shares of the Company’s common stock at an exercise price of $2.29 per share. The warrant is immediately exercisable for 147,600 shares and expires on September 15, 2031. On March 14, 2022, in connection with the funding of the Second Tranche Term Loan, the Company issued a warrant exercisable for 98,399 shares of the Company’s common stock at an exercise price of $2.29 per share. The warrant is immediately exercisable for 98,399 shares and expires on September 15, 2031. No warrants had been exercised as of June 30, 2022. Any shares of the Company’s common stock issued upon exercise of the warrants are permitted to be settled in unregistered shares. The warrants are classified as equity as they meet all of the conditions under GAAP for equity classification. The Company has calculated the fair value of the warrants for initial measurement and date of funding of the Second Tranche Term Loan, and reassesses whether equity classification for the warrants is appropriate upon any changes to the warrants or capital structure, at each balance sheet date. The Company determined that the fair value of the warrants issued in connection with the First Tranche Term Loan and Second Tranche Term Loan was $0.3 million and $0.2 million, respectively. The specific assumptions used to determine the fair value of the warrants were as follows: First Tranche Second Tranche Term Loan Term Loan Expected volatility 95 % 93 % Expected dividends None None Expected term 5.00 Years 5.00 Years Risk-free rate 0.81 % 2.10 % Derivative Liability The Additional Warrants’ (as defined below) derivative liability will be remeasured each reporting period until settled or extinguished with subsequent changes in fair value recorded through other income (expense), net in the condensed statements of operations. The fair value of the Additional Warrants derivative liability was determined using a Black-Scholes option pricing model based on the same input assumptions above, with an additional assessment required for the probability that the Additional Tranche Term Loans will be funded which would trigger the issuance of the Additional Warrants. The Company is conditionally obligated to issue a fixed number of additional warrants (“Additional Warrants”) in the amount of 344,398 shares upon the funding of the Second, Third and Fourth Tranche Term Loans with the same exercise price and contractual term. The contingent obligation to issue the Additional Warrants did not meet the derivative scope exception or equity classification criteria and were accounted for as a derivative liability. The contingently issuable Additional Warrants derivative liability had an initial fair value of $ million and was recorded as additional debt discount and as a separate derivative liability within other long-term liabilities in the condensed balance sheet. As a result of the funding of the Second Tranche Term Loan, the Company issued a warrant exercisable for 98,399 shares of the Company’s common stock at $2.29 per share. Upon issuing the warrants, the Company reclassified the related portion of its Additional Warrants derivative liability into equity. The remaining Additional Warrant Liability that remains outstanding was remeasured as of period end. The The following table provides a reconciliation of the beginning and ending balances for the Company’s Additional Warrants derivative liability recognized in connection with the term loan measured at fair value using significant unobservable inputs (Level 3): Additional Warrants Balance at December 31, 2021 $ 331 Fair value of Additional Warrant Derivative Liability issued during the period — Change in fair value (109) Derecognition (206) Balance at June 30, 2022 $ 16 The specific assumptions used to determine the fair value of the warrants as of June 30, 2022, and December 31, 2021 were as follows: June 30, December 31, 2022 2021 Expected volatility 97 % 95 % Expected dividends None None Expected term 5.00 Years 5.00 Years Risk-free rate 3.01 % 1.26 % |

Income taxes | 11. Income taxes Deferred tax assets and liabilities are determined based on the difference between the financial statement and tax bases of assets and liabilities using enacted tax rates in effect for the year in which the differences are expected to reverse. Valuation allowances are provided if based upon the weight of available evidence, it is more likely than not that some or all of the deferred tax assets will not be realized. The Company has evaluated the positive and negative evidence bearing upon the realizability of its deferred tax assets, including its net operating losses. Based on its history of operating losses, the Company believes that it is more likely than not that the benefit of its deferred tax assets will not be realized. Accordingly, the Company has provided a full valuation allowance for deferred tax assets as of June 30, 2022, and December 31, 2021. |

Summary of significant accounting policies | |
Basis of presentation | Basis of presentation The condensed financial statements of the Company included herein have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission (the “SEC”). Certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) have been condensed or omitted from this report, as is permitted by such rules and regulations. The accompanying condensed financial statements reflect all adjustments consisting of normal, recurring adjustments that are necessary for a fair presentation of the financial position, results of operations and cash flows for the interim periods presented. Interim results are not necessarily indicative of results for a full year. Accordingly, these condensed financial statements should be read in conjunction with the financial statements included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2021 (the “Annual Report”) filed with the SEC on March 23, 2022. From time to time, new accounting pronouncements are issued by the Financial Accounting Standards Board (“FASB”), or other standard setting bodies and adopted by the Company as of the specified effective date. Unless otherwise discussed, the impact of recently issued standards that are not yet effective will not have a material impact on the Company’s financial statements upon adoption. Under the Jumpstart Our Business Startups Act of 2012, as amended (the “JOBS Act”), the Company meets the definition of an emerging growth company, and has elected the extended transition period for complying with new or revised accounting standards, which delays the adoption of these accounting standards until they would apply to private companies. |
Use of estimates | Use of estimates The condensed financial statements are prepared in conformity with GAAP. This process requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities as of the date of the financial statements and the reported amounts of expenses during the reporting period. Actual results could differ from those estimates. |
Risk and uncertainties | Risk and uncertainties The Company’s future results of operations involve a number of risks and uncertainties. Factors that could affect the Company’s future operating results and cause actual results to vary materially from expectations include, but are not limited to, uncertainty of: the impact of COVID-19 on future clinical study results, the scope, timing, rate of progress, and expense of the Company’s ongoing as well as any additional preclinical studies, clinical studies, and other research and development activities, clinical study enrollment rate or design, the manufacturing of the Company’s product candidates, significant and changing government regulation, and the timing and receipt of any regulatory approvals. |
Recently issued accounting pronouncement | Recently issued accounting pronouncement In February 2016, the FASB issued ASU No. 2016-02, Leases fiscal years beginning after December 15, 2022, and early adoption is permitted. The Company anticipates that the adoption of this standard will have an impact on its balance sheet due to the recognition of right-of-use assets and lease liabilities; however, the Company is currently evaluating the impact that the adoption of ASU 2016-02 may have on its condensed financial statements. |
