Aptevo Therapeutics Files Provisional Patent for Fifth Bispecific Antibody APVO711, Intended for the Treatment of Solid Tumors
Aptevo Therapeutics has announced the filing of a provisional patent for APVO711, a bispecific antibody aimed at treating solid tumors like melanoma and lung carcinoma. This innovative candidate, based on their proprietary ADAPTIR platform, engages PD-L1 and CD40 to potentially enhance T cell activation while maintaining a favorable safety profile. Pre-clinical studies are set to begin this year, expanding Aptevo's oncology portfolio to five candidates. CEO Marvin White emphasized the promising efficacy of their existing candidate, APVO436, suggesting APVO711 could yield similar results.

New PD-L1 x CD40 Candidate Built on Proprietary ADAPTIR™ Platform, Enters Pre-Clinical Pipeline
SEATTLE, WA / ACCESSWIRE / January 9, 2023 / 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 announced that the Company has filed a provisional patent with the U.S. Patent and Trademark Office (USPTO) pertaining to an anti-PD-L1 x anti-CD40 compound, APVO711, with the potential to fight a range of solid malignancies such as head and neck squamous cell carcinoma, melanoma, and carcinomas of the lung, gastrointestinal tract and colon. The Company plans to initiate pre-clinical studies this year.
"Identifying new approaches to address the unmet needs of cancer patients is critical and APVO711 represents just such a new approach. This bispecific molecule targeting PD-L1 and CD40 is designed to function with new mechanisms of action and to synergistically induce a biological response. This is achieved by simultaneously engaging in two validated T cell activating mechanisms: 1) by blocking of PD-L1/PD-1 inhibitory pathway and 2) by enhancing T cell priming through activation of the stimulatory receptor CD40 on antigen presenting cells. APVO711 is designed to activate CD40 only in the presence of PD-L1 for an ideal safety profile." said Michelle Nelson, PhD, Director, Immunobiology at Aptevo. "Our goal in pre-clinical studies will be to continue to evaluate that APVO711 has the desired anti-tumor efficacy, mechanisms of action and safety profile we are looking for in our latest pipeline candidate."
"We are very pleased to announce that APVO711 is entering pre-clinical studies. This new compound expands our anti-cancer portfolio to five molecules and provides potential for another novel pathway to more effective cancer therapies in solid tumors," said Marvin L. White, President, and CEO of Aptevo Therapeutics. "As evidenced by clinical performance to date for APVO436, which has delivered compelling efficacy and safety data, we believe our additional ADAPTIR candidates, such as APVO711, have the potential to deliver similar outcomes."

For instance, actual results may differ materially from those indicated by such forward-looking statements as a result of various important factors, including the uncertainties inherent in the results of preliminary data and pre-clinical studies being predictive of the results of later-stage clinical trials, the availability and timing of data from ongoing clinical trials, expectations for the timing and steps required in the regulatory review process, including our ability to obtain regulatory clearance, expectations for regulatory approvals, the impact of competitive products, our ability to enter into agreements with strategic partners or raise funds on acceptable terms or at all and other matters that could affect the availability or commercial potential of Aptevo's product candidates, business or economic disruptions due to catastrophes or other events, including natural disasters or public health crises such as the coronavirus (referred to as COVID-19), geopolitical risks, including the current war between Russia and Ukraine, and macroeconomic conditions such as economic uncertainty, rising inflation and interest rates, increased market volatility and decreased consumer confidence.
