Advances Phase 1/1b Study of APVO436 for Treatment of Acute Myeloid Leukemia and High-Grade Myelodysplastic Syndrome; Dosing in Cohort 10 Ongoing

SEATTLE, WA / ACCESSWIRE / May 11, 2021 / Aptevo Therapeutics Inc. ("Aptevo" or "the Company") (NASDAQ:APVO), a clinical-stage biotechnology company focused on developing novel immuno-oncology therapeutics based on its proprietary ADAPTIR™ and ADAPTIR-FLEX™ platform technologies, today reported its financial results for the quarter ended March 31, 2021.

"We are pleased to report progress in the clinical trial of our ADAPTIR platform candidate APVO436, with the dose limiting toxicity (DLT) evaluation in cohorts 1 through 9 now completed and 44 patients enrolled to date in cohorts 1-10. We remain confident in the clinical impact potential of APVO436 and our platform technologies, and look forward to sharing interim data readouts from our ongoing APVO436 study later this year," said Mr. Marvin White, President and CEO of Aptevo. "The transaction with HCR, which we completed in March 2021, provided significant non-dilutive funding, which adds to our cash runway and helps fund the company through the next twelve months."

First Quarter 2021 Financial Results Summary

As announced in March, Aptevo received $35 million ("the Investment Amount") from its sale of the right to royalty payments made by Pfizer Inc. ("Pfizer") with respect to net sales of RUXIENCE^® to an entity managed by HealthCare Royalty Management, LLC ("HCR"). Aptevo 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"). The Royalty Purchase Agreement further provides that, once HCR reaches aggregate royalty payments totaling 190% of the Investment Amount plus the Milestone Amounts to the extent paid by HCR to the Company, Aptevo will be entitled to receive 50% of any additional royalty payments by Pfizer thereafter. In connection with this royalty purchase agreement, Aptevo amended its term loan agreement with MidCap Financial and used $10 million of the proceeds received to pay down outstanding principal.

Cash Position: Aptevo had cash and cash equivalents as of March 31, 2021 totaling $58.8 million, including restricted cash of $1.3 million. The restricted cash is expected to be released over the next twelve months.

Royalty Revenue: Royalty revenue was $2.4 million for the three months ended March 31, 2021, related to the royalty from Pfizer on global net sales of RUXIENCE^®, a biosimilar to the drug RITUXAN^®, launched by Pfizer in early 2020. RUXIENCE^® is a trademark of Pfizer; RITUXAN^® is a trademark of Biogen. Due to our continuing involvement under the Definitive 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.

Research and Development Expenses: Research and development expenses increased to $5.4 million for the three months ended March 31, 2021 from $4.0 million for the three months ended March 31, 2020 as we continue to invest in the APVO436 clinical trial and our preclinical candidates, including ALG.APV-527, APVO603 and APVO442.

General and Administrative Expenses: For the three months ended March 31, 2021, general and administrative expenses increased to $3.9 million from $3.6 million for March 31, 2020, with higher costs for professional services.

Other Expense, Net: Other expense, net consists primarily of interest on debt and costs related to debt extinguishment. Other expense, net was $0.8 million for the three months ended March 31, 2021 and $2.4 million for the three months ended March 31, 2020. A slight increase in interest expense this quarter was offset by a significant decrease due to a loss on extinguishment of debt of $2.1 million recognized in the first quarter of 2020 when we repaid our previous loan to MidCap Financial using the proceeds from the sale of Aptevo BioTherapeutics LLC.

Discontinued Operations: Income from discontinued operations was $0.4 million for the three months ended March 31, 2021 and $12.9 million for the three months ended March 31, 2020. For the three months ended March 31, 2021, we collected a deferred payment of $0.2 million from Medexus related to fourth quarter 2020 IXINITY sales and $0.2 million from the Saol Therapeutics, related to the 2017 sale of the Hyperimmune Business to them. For the three months ended March 31, 2020, we recognized net income from discontinued operations totaling $12.9 million. This included the gain on the sale of Aptevo BioTherapeutics LLC of $14.3 million and net operating losses from Aptevo BioTherapeutics LLC of $1.6 million related to the period prior to the sale on February 28, 2020.

Net Income (Loss): Aptevo's net loss for the three-month period ended March 31, 2021 was $(7.3) million or $(1.64) per share, as compared to a net income of $2.9 million or $0.89 per share for the corresponding period in 2019. Our net loss from continuing operations for the first quarter of 2021 was $(7.6) million compared to $(10.0) million in the first quarter of 2020.

Liability Related to Sale of Future Royalties: We treat the Royalty Purchase Agreement with HCR 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. 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.
