Accounting Policies [Abstract] | |
Nature of Business and Significant Accounting Policies | Note 1. Nature of Business and Significant Accounting Policies Organization and Liquidity Aptevo Therapeutics Inc. (Aptevo, we, us, or the Company) is a clinical-stage, research and development biotechnology company focused on developing novel immunotherapeutic candidates for the treatment of different forms of cancer. We have developed two versatile and enabling platform technologies for rational design of precision immune stimulatory drugs. Our lead clinical candidate, APVO436, and preclinical candidates, ALG.APV-527 and APVO603, were developed using our ADAPTIR™ modular protein technology platform. Our preclinical candidate APVO442 was developed using our ADAPTIR-FLEX™ modular protein technology platform. We are currently trading on the Nasdaq Capital Market under the symbol “APVO.” The accompanying financial statements have been prepared on a basis that assumes we will continue as a going concern and which contemplates the realization of assets and satisfaction of liabilities and commitments in the normal course of business. For the three and six months ended June 30, 2021, we had a net loss of $7.9 million and $15.2 million, respectively. We had an accumulated deficit of $200.8 million as of June 30, 2021. For the six months ended June 30, 2021, net cash used in our operating activities was $12.6 million. We have suffered recurring losses from operations and negative cash flows from operating activities. We believe that our existing cash resources, the cash to be generated from future deferred payments and milestones, the cash generated from warrant exercises, and release of restricted cash securing letters of credit, will be sufficient to meet our projected operating requirements and debt service for at least twelve months from the date of issuance of these financial statements. We may choose to raise additional funds to support our operating and capital needs. We continue to face significant challenges and uncertainties and, as a result, our available capital resources may be consumed more rapidly than currently expected due to: (a) changes we may make to the business that affect ongoing operating expenses; (b) changes we may make in our business strategy; (c) changes we may make in our research and development spending plans; (d) potential decreases in our expected milestone and deferred payments from Medexus Pharmaceuticals Inc. (Medexus) with respect to IXINITY; (e) whether and to what extent future proceeds are received under our Royalty Purchase Agreement; and (f) other items affecting our forecasted level of expenditures and use of cash resources. We may attempt to obtain additional funding through our existing equity sales agreement with Lincoln Park or our Equity Distribution Agreement with Piper Sandler & Co (Piper Sandler), or other public or private financing, collaborative arrangements with strategic partners, or through credit lines or other debt financing sources to increase the funds available to fund operations. However, we may not be able to secure such funding in a timely manner or on favorable terms, if at all. Furthermore, if we issue equity or debt securities to raise additional funds, our existing stockholders may experience dilution, and the new equity or debt securities may have rights, preferences, and privileges senior to those of our existing stockholders. If we raise additional funds through collaboration, licensing, or other similar arrangements, it may be necessary to relinquish valuable rights to our potential products or proprietary technologies, or grant licenses on terms that are not favorable to us. Without additional funds, we may be forced to delay, scale back, or eliminate some of our research and development activities or other operations and potentially delay product development in an effort to provide sufficient funds to continue our operations. If any of these events occurs, our ability to achieve our development and commercialization goals may be adversely affected. Given the global economic climate and additional or unforeseen effects from the COVID-19 pandemic, we may experience delays or difficulties in the financing environment and raising capital due to economic uncertainty. Basis of Presentation The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (GAAP). These condensed consolidated financial statements include all adjustments, which include normal recurring adjustments, necessary for the fair presentation of the Company’s financial position. These unaudited interim consolidated financial statements should be read in conjunction with the audited consolidated financial statements as of and for the year ended December 31, 2020, and the notes thereto, which are included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2020. The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from these estimates and changes in these estimates are recorded when known. The condensed consolidated financial statements include the accounts of the Company and our wholly owned subsidiaries: Aptevo Research and Development LLC and Aptevo BioTherapeutics LLC (for the period prior to its sale on February 28, 2020) In March 2020, we effected a 1-for-14 reverse stock split (the “Reverse Split”) of our common stock pursuant to which every 14 shares of our common stock issued and outstanding as of March 26, 2020 were automatically combined into one issued and outstanding share of common stock. No fractional shares were issued as a result of the reverse stock split. Stockholders of record who would otherwise have been entitled to receive a fractional share received a cash payment in lieu thereof. All share and per share information with respect to our common stock have been restated to reflect the effect of the Reverse Split for all periods presented. Use of Estimates The preparation of financial statements in conformity with GAAP requires estimates and assumptions that affect the reported amounts of assets and liabilities, revenues and expenses, and related disclosures of contingent liabilities in the condensed consolidated financial statements and accompanying notes. Estimates are used for, but not limited to, forecasted royalties, effective interest rates, clinical accruals, useful lives of equipment, commitments and contingencies, and stock-based compensation forfeiture rates. Given the global economic climate and additional or unforeseen effects from the COVID-19 pandemic, these estimates are becoming more challenging, and actual results could differ materially from those estimates. Significant Accounting Policies Liability Related to Sale of Future Royalties and Non-Cash Interest Expense On March 30, 2021, the Company entered into and closed a royalty purchase agreement (the Royalty Purchase Agreement) with an entity managed by HealthCare Royalty Management, LLC (HCR) the Company is eligible to receive additional payments in aggregate of up to an additional $32.5 million based on the achievement of sales milestones in 2021, 2022, and 2023 (collectively, the Milestone Amounts) We treat the Royalty Purchase Agreement with HCR (see Note 7) as a debt financing, amortized under the effective interest rate method over the estimated life of the related expected royalty stream. The liabilities related to sale of future royalties and the debt amortization are based on our current estimates of future royalties expected to be paid over the life of the arrangement. To the extent total future royalties collected are an amount less than the liability, the Company is not obligated to fund any such shortfall. We will periodically assess the expected royalty payments using projections from external sources. To the extent our estimates of future royalty payments are greater or less than previous estimates or the estimated timing of such payments is materially different than previous estimates, we will adjust the effective interest rate and recognize related non-cash interest expense on a prospective basis. We are not obligated to repay the proceeds received under the Royalty Purchase Agreement with HCR. Due to our continuing involvement under the collaboration and license agreement originally between Trubion and Wyeth , we continue to recognize royalty revenue on net sales of RUXIENCE and record the royalty payments to HCR as a reduction of the liability when paid. As such payments are made to HCR, the balance of the liability will be effectively repaid over the life of the Royalty Purchase Agreement. Debt Modification On March 30, 2021, we amended The amended Credit Agreement was accounted for under ASC 470-50, Debt Modifications and Extinguishments as a , rather than an extinguishment, based on a comparison of the present value of the cash flows under the terms of the debt immediately before and after the amendment, which resulted in a change of less than 10%. Unamortized issuance costs as of the date of modification will be amortized to interest expense using the effective interest method over the repayment term. Other Significant Accounting Policies Our other significant accounting policies were reported in our Annual Report on Form 10-K for the year ended December 31, 2020 that was filed with the SEC on March 31, 2021. Our other significant accounting policies have not changed materially from the policies previously reported. Recent Accounting Pronouncements Not Yet Adopted ASU 2020-04, “ Reference Rate Reform (Topic 848)” An entity may elect to apply the amendments prospectively from March 12, 2020 through December 31, 2022. Our credit agreement with MidCap Financial currently references LIBOR and also provides that we may amend the credit agreement to reflect an alternative rate of interest upon the phase out of LIBOR. We are currently evaluating the impact that ASU 2020-04 may have on our consolidated financial statements. |

Discontinued Operations And Disposal Groups [Abstract] | |
Discontinued Operations | Note 2. Discontinued Operations The accompanying financial statements include results from discontinued operations from two separate transactions: the sale of our hyperimmune business in 2017, from which we received a payment in 2021 related to the collection of a certain accounts receivable, and our Aptevo BioTherapeutics LLC business, which was sold in 2020. On February 28, 2020, we entered into an LLC Purchase Agreement with Medexus, pursuant to which we sold all of the issued and outstanding limited liability company interests of Aptevo BioTherapeutics LLC, a wholly owned subsidiary of Aptevo. As a result of the transaction, Medexus obtained all rights, title and interest to the IXINITY product and the related Hemophilia B business and intellectual property . The net gain on sale of Aptevo BioTherapeutics, totaling $14.3 million, was calculated as the difference between the fair value of the consideration received for Aptevo BioTherapeutics, less the net carrying value of the assets transferred to Medexus, less the transaction costs incurred and a working capital adjustment. We recorded the gain on sale in the quarter ended March 31, 2020. The following table represents the components attributable to income from discontinued operations in the unaudited condensed consolidated statements of operations (in thousands): For the Three Months Ended June, For the Six Months Ended June, 2021 2020 2021 2020 Loss from operations - Aptevo BioTherapeutics — — — (1,580 ) Gain on sale of Aptevo BioTherapeutics — — — 14,338 Payment from Saol — — 227 — Deferred payment from Medexus 132 — 319 140 Income from discontinued operations $ 132 $ — $ 546 $ 12,898 The LLC Purchase Agreement with Medexus entitles us to future deferred payments and royalties. For the three months ended June 30, 2021, we collected Medexus communicated their second quarter 2021 net IXINITY sales to Aptevo in July and expects to make a deferred payment, within 45 days after quarter-end per the LLC Purchase Agreement, to Aptevo of approximately $0.1 million. As such, we will record the deferred payment amount related to Medexus’ second quarter sales of IXINITY as a gain when collected. There was no amortization for Aptevo BioTherapeutics in the three or six months ended June 30, 2021 and amortization was $0.1 million in the three and six months ended June 30, 2020. There was no depreciation or capital expenditures for the three or six months ended June 30, 2021 or June 30, 2020. Significant operating non-cash items include the gain on sale of Aptevo BioTherapeutics of $14.3 million for the six months ended June 30, 2020. There were no significant investing non-cash items for the six months ended June 30, 2021 and 2020. |

Organization Consolidation And Presentation Of Financial Statements [Abstract] | |
Collaboration Agreements | Note 3. Collaboration Agreements Alligator On July 20, 2017, our wholly owned subsidiary Aptevo Research and Development LLC (Aptevo R&D), entered into a collaboration and option agreement (the Collaboration Agreement) with Alligator Bioscience AB (Alligator), pursuant to which Aptevo and Alligator will collaboratively develop ALG.APV-527, a lead bispecific antibody candidate simultaneously targeting 4-1BB (CD137), a member of the TNFR superfamily of a costimulatory receptor found on activated T-cells, and 5T4, a tumor antigen widely overexpressed in a number of different types of cancer. We assessed the arrangement in accordance with ASC 606 and concluded that the contract counterparty, Alligator, is not a customer. As such the arrangement is not in the scope of ASC 606 and is instead treated as a collaborative agreement under ASC 808 – Collaborative Arrangements (ASC 808). In accordance with ASC 808, we concluded that because the Collaboration Agreement is a cost sharing agreement, there is no revenue. We recorded a $0.1 million increase and an immaterial increase in research and development expense June 30, 2020, respectively. |

Fair Value Disclosures [Abstract] | |
Fair Value Measurements | Note 4. Fair Value Measurements The Company’s estimates of fair value for financial assets and financial liabilities are based on the framework established in the fair value accounting guidance. The framework is based on the inputs used in valuation, it gives the highest priority to quoted prices in active markets and requires that observable inputs be used in the valuations when available. The disclosure of fair value estimates in the fair value accounting guidance hierarchy is based on whether the significant inputs into the valuation are observable. In determining the level of the hierarchy in which the estimate is disclosed, the highest priority is given to unadjusted quoted prices in active markets and the lowest priority to unobservable inputs that reflect the Company’s significant market assumptions. The level in the fair value hierarchy within which the fair value measurement is reported is based on the lowest level input that is significant to the measurement in its entirety. The three levels of the hierarchy are as follows: Level 1— Quoted prices in active markets for identical assets and liabilities; Level 2— Inputs other than quoted prices in active markets that are either directly or indirectly observable; and Level 3— Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. At June 30, 2021 and December 31, 2020, we had $55.9 million and $35.4 million in Level 1 money market funds, respectively. The carrying amounts of our money market funds approximate their fair value. At June 30, 2021 and December 31, 2020, we did not have any Level 2 or Level 3 assets. |

Debt Disclosure [Abstract] | |
Debt | Note 6. Debt Credit Agreement On August 5, 2020, we entered into a Credit and Security Agreement (the Credit Agreement), with MidCap Financial. The Credit Agreement provided us with up to $25.0 million of available borrowing capacity under a term loan facility. The full $25.0 million was drawn on the closing date of the Credit Agreement The United Kingdom’s Financial Conduct Authority (the “FCA”), which regulates LIBOR, has announced that it intends to phase out LIBOR by the end of 2021. It is unclear if at that time LIBOR will cease to exist or if new methods of calculating LIBOR will be established such that it continues to exist after 2021. O On November 6, 2020, Kevin Tang and his related entities filed a statement on Schedule 13D to report the purchase of 1,760,000 shares of the Company’s common stock, which at the time represented approximately 54 % of the Company’s issued and outstanding shares of the Company’s common stock. This acquisition of voting stock triggered a change in control, resulting in an Event of Default under Section 10.1(a)(ii) of the Credit Agreement. On November 10, 2020, the Company obtained a waiver from MidCap Financial pursuant to which, among other things, MidCap Financial waived such Event of Default and MidCap Financial and the Company agreed that an immediate event of default under the Credit Agreement will be deemed to have occurred in the event that (a) a majority of the seats on the Company’s board of directors are occupied by persons who were neither (i) nominated by the Company’s board of directors nor (ii) appointed by the directors so nominated, and (b) Tang has appointed the majority of the Company’s board of directors. No other events of default have occurred with respect to the Credit Agreement. On March 30, 2021, we amended our Credit Agreement with MidCap Financial and used $10.0 million of the proceeds received from the Royalty Purchase Agreement to pay down the outstanding principal under the Credit Agreement from $25.0 million to $15.0 million. $10.0 million of the remaining $15.0 million principal balance will be payable on March 31, 2022. Beginning March 1, 2022, monthly repayment of the remaining $5.0 million of principal will commence and continue for the final 30 months of the loan term. If the Company sells the IXINITY deferred payment stream and milestones prior to full repayment of this $5.0 million principal amount, under the agreement with MidCap Financial, we will be required to use the proceeds from the sale to pay down the outstanding loan principal balance. MidCap Financial also released its security interest in the RUXIENCE royalty payments. A fee of $0.6 million was paid by the Company to MidCap Financial in connection with the amendment in lieu of the formula-based fee previously required. T he amended Credit Agreement was accounted for as a , rather than an extinguishment, based on a comparison of the present value of the cash flows under the terms of the debt immediately before and after the amendment, which resulted in a change of less than 10%. Unamortized issuance costs as of the date of modification will be amortized to interest expense using the effective interest method over the repayment term. As of June 30, 2021, we classified $10.7 million of the remaining $15.0 million principal of the amended Credit Agreement to current portion of long-term debt on the condensed consolidated balance sheet. The amended Credit Agreement states $10.0 million of the remaining $15.0 million principal balance will be payable on March 31, 2022. Additionally, within the next twelve months, we will pay $0.7 million to MidCap Financial for monthly repayments of outstanding principal beginning on March 1, 2022. This facility is subject to a subjective acceleration clause that could be invoked by MidCap Financial upon the occurrence of any event MidCap Financial deems to have a material adverse effect on our ability to repay the lender. |

Sale Of Future Royalties Liability Disclosure [Abstract] | |
Liability Related to Sale of Future Royalties | Note 7. Liability Related to Sale of Future Royalties In March 2021, we are eligible to receive additional payments in aggregate of up to an additional $32.5 million based on the achievement of sales milestones in 2021, 2022, and 2023 (collectively, the Milestone Amounts) The proceeds received from HCR of $35.0 million were recorded as a liability, net of transaction costs of $1.1 million, which will be amortized over the estimated life of the arrangement using the effective interest method. In order to determine the amortization of the liability, we are required to estimate the total amount of future royalty payments to be received by HCR over the life of the arrangement. The total amount of royalty payments received by HCR under the Royalty Purchase Agreement, less the net proceeds we received of $33.9 million, is recorded as non-cash interest expense over the life of the arrangement using the effective interest method. We maintain our rights under the collaboration and license agreement originally between Trubion and Wyeth, with the exception of the cash flows of the RUXIENCE royalty payments purchased by HCR. Due to our continuing involvement under the collaboration and license agreement originally between Trubion and Wyeth , we continue to recognize royalty revenue on net sales of RUXIENCE and record the royalty payments to HCR as a reduction of the liability when paid. As such payments are made to HCR, the balance of the liability will be effectively repaid over the life of the Royalty Purchase Agreement. To the extent total future royalties collected are an amount less than the liability, the Company is not obligated to fund any such shortfall. We estimate the effective interest rate used to record non-cash interest expense under the Royalty Purchase Agreement based on the estimate of future royalty payments to be received by HCR. As of June 30, 2021, the estimated effective interest rate under the agreement was 21.9%. Over the life of the arrangement, the actual effective interest rate will be affected by the amount and timing of the royalty payments received by HCR and changes in our forecasted royalties. Periodically, we will reassess our estimate of total future royalty payments to be received by HCR, and prospectively adjust the effective interest rate and amortization of the liability as necessary. The following table presents the changes in the liability related to the sale of future royalties under the Royalty Purchase Agreement with HCR (in thousands): Three Months Ended June 30, 2021 Liability related to sale of future royalties, beginning balance $ 33,920 Non-cash interest expense 1,848 RUXIENCE royalties paid to HCR (2,421 ) Liability related to sale of future royalties, ending balance 33,347 Current portion of liability related to sale of future royalties (12,810 ) Liability related to sale of future royalties, non-current $ 20,537 |

Earnings Per Share [Abstract] | |
Net Income (Loss) per Share | Note 9. Net Income (Loss) per Share Basic net income (loss) per share is calculated by dividing the net income (loss) by the weighted average number of common shares outstanding for the period. Diluted net income (loss) per share is computed by dividing the net income (loss) by the weighted average number of common share equivalents outstanding for the period using the as-if converted method. For the purpose of this calculation, warrants, stock options and restricted stock units (RSUs) are only included in the calculation of diluted net income (loss) per share when their effect is dilutive. We utilize the control number concept in the computation of diluted earnings per share to determine whether potential common stock instruments are dilutive. The control number used is loss from continuing operations or income from discontinued operations. The control number concept requires that the same number of potentially dilutive securities applied in computing diluted earnings per share from continuing operations be applied to all other categories of income or loss, regardless of their anti-dilutive effect on such categories. Therefore, no dilutive effect has been recognized in the calculation of income from discontinued operations per share. Common stock equivalents include warrants, stock options and unvested RSUs. The following table presents the computation of basic and diluted net income (loss) per share (in thousands, except share and per share amounts): For the Three Months Ended June 30, For the Six Months Ended June 30, 2021 2020 2021 2020 Net loss from continuing operations $ (8,064 ) $ (6,803 ) $ (15,734 ) $ (16,804 ) Income from discontinued operations 132 — 546 12,898 Net loss $ (7,932 ) $ (6,803 ) $ (15,188 ) $ (3,906 ) Basic and diluted net income (loss) per share: Net loss from continuing operations $ (1.78 ) $ (2.10 ) $ (3.51 ) $ (5.14 ) Net income from discontinued operations $ 0.03 $ — $ 0.12 $ 3.95 Net loss per basic share $ (1.75 ) $ (2.10 ) $ (3.39 ) $ (1.19 ) Weighted-average shares used to compute per share calculations 4,536,517 3,232,811 4,477,821 3,269,410 The following table represents all potentially dilutive shares, which were all anti-dilutive and therefore excluded from the calculation of diluted net loss per share: As of June 30, (in thousands) 2021 2020 Warrants 351 1,571 Outstanding options to purchase common stock 368 340 Unvested RSUs 64 12 |

Equity [Abstract] | |
Equity | Note 10. Equity Equity Distribution Agreement On December 14, 2020, we entered into an Equity Distribution Agreement (the Equity Distribution Agreement) with Piper Sandler. The Equity Distribution Agreement provides that, upon the terms and subject to the conditions set forth therein, we may issue and sell through Piper Sandler, acting as sales agent, shares of our common stock, $0.001 par value per share having an aggregate offering price of up to $50.0 million. This offering supersedes and replaces the program we commenced in December 2017. Purchase Agreement On December 20, 2018, we entered into the Purchase Agreement, and a registration rights agreement, with Lincoln Park. Pursuant to the Purchase Agreement, Lincoln Park has committed to purchase up to $35.0 million worth of our common stock over a 36-month period commencing on February 13, 2019, the date the registration statement covering the resale of the shares was declared effective by the SEC. Under the Purchase Agreement, on any business day selected by us, we may direct Lincoln Park to purchase shares of our common stock provided that Lincoln Park’s maximum commitment on any single day does not exceed $2.0 million. The purchase price per share will be based off of prevailing market prices of our common stock immediately preceding the time of sale; provided, however, that we cannot direct any such purchase if the prevailing market price is less than $1.00. In the three months ended June 30, 2021, the Company issued approximately 0.4 million shares of common stock to Lincoln Park under the 2018 Purchase Agreement. We received $10.2 million in proceeds from issuance of these shares and now have a remaining $24.8 million worth of shares of our common stock that we may direct Lincoln Park to purchase pursuant to our Purchase Agreement with them Rights Plan On November 8, 2020, our Board of Directors (Board) approved and adopted a Rights Agreement, dated as of November 8, 2020, by and between the Company and Broadridge Corporate Issuer Solutions, Inc., as rights agent, pursuant to which the Board declared a dividend of one preferred share purchase right (each, a Right) for each outstanding share of the Company’s common stock held by stockholders as of the close of business on November 23, 2020. When exercisable, each right initially would represent the right to purchase from the Company one one-thousandth of a share of a newly-designated series of preferred stock, Series A Junior Participating Preferred Stock, par value $0.001 per share, of the Company, at an exercise price of $400.00 per one one-thousandth of a Series A Junior Participating Preferred Share, subject to adjustment. Subject to various exceptions, the Rights become exercisable in the event any person (excluding certain exempted or grandfathered persons) becomes the beneficial owner of ten percent (10%) or more of the Company’s common stock without the approval of the Board. C onverted Equity Awards Incentive Plan In connection with the spin-off from Emergent BioSolutions, Inc. (Emergent) in August 2016, we adopted the Converted Equity Awards Incentive Plan (Converted Plan) and outstanding equity awards of Emergent held by Aptevo employees were converted into or replaced with equity awards of Aptevo (Conversion Awards). A total of 0.1 million shares of Aptevo common stock have been authorized for issuance under the Converted Plan. 2016 Stock Incentive Plan On August 1, 2016, the Company adopted the 2016 Stock Incentive Plan (2016 SIP). A total of 0.2 million shares of Aptevo common stock have been authorized for issuance under the 2016 SIP in the form of equity stock options. On May 31, 2017, at the 2017 Annual Meeting of Stockholders (Annual Meeting), the Company’s stockholders approved the amendment and restatement of the Company’s 2016 SIP (Restated 2016 Plan) to, among other things, increase the number of authorized shares issuable by 0.1 million shares of Aptevo common stock. The Restated 2016 Plan was previously approved, subject to stockholder approval, by the Board of Directors of the Company. 2018 Stock Incentive Plan On June 1, 2018, at the 2018 Annual Meeting of the Stockholders, the Company’s stockholders approved a new 2018 Stock Incentive Plan (2018 SIP), which replaced the Restated 2016 Plan on a go-forward basis. All stock options, RSUs or other equity awards granted subsequent to June 1, 2018 have been and will be issued out of the 2018 SIP, which has 0.3 million shares of Aptevo common stock authorized for issuance. The 2018 Plan became effective immediately upon stockholder approval at the 2018 Annual Meeting of the Stockholders. Any shares subject to outstanding stock awards granted under the 2016 SIP that (a) expire or terminate for any reason prior to exercise or settlement; (b) are forfeited because of the failure to meet a contingency or condition required to vest such shares or otherwise return to the Company; or (c) otherwise would have returned to the 2016 SIP for future grant pursuant to the terms of the 2016 Plan (such shares, the “Returning Shares”) will immediately be added to the share reserve under the 2018 SIP as and when such shares become Returning Shares, up to a maximum of 0.3 million shares. As of June 30, 2021, there are less than 0.1 million shares available to be granted under the 2018 SIP. Stock options under the 2018 SIP generally vest pro rata over a three-year three-year Stock-Based Compensation Expense Stock-based compensation expense includes amortization of stock options and RSUs granted to employees and non-employees and has been reported in our condensed consolidated statements of operations as follows: For the Three Months Ended June 30, For the Six Months Ended June 30, (in thousands) 2021 2020 2021 2020 Research and development $ 172 $ 114 $ 411 $ 284 General and administrative 400 187 735 430 Total stock-based compensation expense $ 572 $ 301 $ 1,146 $ 714 The Company accounts for stock-based compensation by measuring the cost of employee services received in exchange for all equity awards granted based on the fair value of the award as of the grant date. The Company recognizes the compensation expense over the vesting period. All assumptions used to calculate the grant date fair value of nonemployee options are generally consistent with the assumptions used for options granted to employees. In the event the Company terminates any of its consulting agreements, the unvested options underlying the agreements would also be cancelled. Stock Options Aptevo utilizes the Black-Scholes valuation model for estimating the fair value of all stock options granted. Set forth below are the assumptions used in valuing the stock options granted: For the Three Months Ended June 30, For the Six Months Ended June 30, 2021 2020 2021 2020 Expected dividend yield 0.00% 0.00% 0.00% 0.00% Expected volatility 98.03% 0.00% 99.53% 83.64% Risk-free interest rate 0.91% 0.00% 0.55% 1.42% Expected average life of options 6 years 6 years 5 years 6 years There were no equity grants made in the three months ended June 30, 2020. Management applied an estimated forfeiture rate of 19% and 23% for the three and six months ended June 30, 2021, respectively, and 8% for the three and six months ended June 30, 2020. The following is a summary of option activity for the six months ended June 30, 2021: Number of Shares Weighted- Average Exercise Price Weighted- Average Remaining Term Aggregate Intrinsic Value Balance at December 31, 2020 212,581 $ 8.32 8.78 $ 5,906,007 Granted 189,080 32.40 Exercised (13,274 ) 8.40 283,572 Forfeited (20,297 ) 28.67 Outstanding at June 30, 2021 368,090 $ 19.80 9.17 $ 2,732,280 Exercisable at June 30, 2021 79,097 $ 8.39 8.50 $ 1,118,038 As of June 30, 2021, we had $4.4 million of unrecognized compensation expense related to options expected to vest over a weighted average period of 2.5 years. The weighted average remaining contractual life of outstanding and exercisable options is 8.5 years. The aggregate intrinsic value in the table above represents the total pretax intrinsic value (the difference between the closing stock price of Aptevo’s common stock on the last trading day of June 2021 and the exercise price, multiplied by the number of in the money options) that would have been received by the option holders had all the option holders exercised their options on the last trading day of the quarter.

The fair value of each RSU has been determined to be the closing trading price of the Company’s common stock on the date of grant as quoted on the Nasdaq Capital Market. Warrants In March 2019, as part of a public offering, we issued warrants to purchase up to 1,725,000 shares of our common stock, 1,571,429 of which have an exercise price of $18.20 per share and have a five-year ten-year |

Accounting Policies [Abstract] | |
Basis of Presentation | Basis of Presentation The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (GAAP). These condensed consolidated financial statements include all adjustments, which include normal recurring adjustments, necessary for the fair presentation of the Company’s financial position. These unaudited interim consolidated financial statements should be read in conjunction with the audited consolidated financial statements as of and for the year ended December 31, 2020, and the notes thereto, which are included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2020. The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from these estimates and changes in these estimates are recorded when known. The condensed consolidated financial statements include the accounts of the Company and our wholly owned subsidiaries: Aptevo Research and Development LLC and Aptevo BioTherapeutics LLC (for the period prior to its sale on February 28, 2020) In March 2020, we effected a 1-for-14 reverse stock split (the “Reverse Split”) of our common stock pursuant to which every 14 shares of our common stock issued and outstanding as of March 26, 2020 were automatically combined into one issued and outstanding share of common stock. No fractional shares were issued as a result of the reverse stock split. Stockholders of record who would otherwise have been entitled to receive a fractional share received a cash payment in lieu thereof. All share and per share information with respect to our common stock have been restated to reflect the effect of the Reverse Split for all periods presented. |
Use of Estimates | Use of Estimates The preparation of financial statements in conformity with GAAP requires estimates and assumptions that affect the reported amounts of assets and liabilities, revenues and expenses, and related disclosures of contingent liabilities in the condensed consolidated financial statements and accompanying notes. Estimates are used for, but not limited to, forecasted royalties, effective interest rates, clinical accruals, useful lives of equipment, commitments and contingencies, and stock-based compensation forfeiture rates. Given the global economic climate and additional or unforeseen effects from the COVID-19 pandemic, these estimates are becoming more challenging, and actual results could differ materially from those estimates. |
Liability Related to Sale of Future Royalties and Non-Cash Interest Expense | Liability Related to Sale of Future Royalties and Non-Cash Interest Expense On March 30, 2021, the Company entered into and closed a royalty purchase agreement (the Royalty Purchase Agreement) with an entity managed by HealthCare Royalty Management, LLC (HCR) the Company is eligible to receive additional payments in aggregate of up to an additional $32.5 million based on the achievement of sales milestones in 2021, 2022, and 2023 (collectively, the Milestone Amounts) We treat the Royalty Purchase Agreement with HCR (see Note 7) as a debt financing, amortized under the effective interest rate method over the estimated life of the related expected royalty stream. The liabilities related to sale of future royalties and the debt amortization are based on our current estimates of future royalties expected to be paid over the life of the arrangement. To the extent total future royalties collected are an amount less than the liability, the Company is not obligated to fund any such shortfall. We will periodically assess the expected royalty payments using projections from external sources. To the extent our estimates of future royalty payments are greater or less than previous estimates or the estimated timing of such payments is materially different than previous estimates, we will adjust the effective interest rate and recognize related non-cash interest expense on a prospective basis. We are not obligated to repay the proceeds received under the Royalty Purchase Agreement with HCR. Due to our continuing involvement under the collaboration and license agreement originally between Trubion and Wyeth , we continue to recognize royalty revenue on net sales of RUXIENCE and record the royalty payments to HCR as a reduction of the liability when paid. As such payments are made to HCR, the balance of the liability will be effectively repaid over the life of the Royalty Purchase Agreement. |
