APVO442 Prostate Cancer Data Presented at the American Association for Cancer Research Annual Meeting
Preclinical Data Support Potential for APVO442 in Difficult-to-Treat Types of Prostate Cancer, Including Metastatic Castration-Resistant Disease
The presentation, entitled "APVO442 is a distinct PSMA x CD3 targeted bispecific candidate designed to optimize T cell fitness and distribution to solid tumors," highlights the potential of APVO442 to treat prostate cancer indications such as metastatic castration-resistant prostate cancer with increased benefit and decreased side effects relative to other potential therapeutics in the bispecific category. Aptevo is working to identify a clinical path for APVO442 and to potentially offer improved treatment options as a monotherapy or combination therapy for patients with difficult-to-treat prostate cancers.
"APVO442 was designed to offer unique tumor fighting and safety properties with the goal of maximizing the patients' own immune response toward tumor killing while minimizing the toxic effects that can be associated with this bispecific therapeutic category, most notably cytokine release syndrome. This is a serious and sometimes treatment-limiting side effect in a clinical setting," said
About APVO442
APVO442 is a bispecific antibody candidate designed to target Prostate Specific Membrane Antigen (PSMA), a tumor antigen that is highly expressed on prostate cancer cells with limited normal tissue expression, and CD3, a signaling component of the T-cell receptor complex. APVO442 contains two binding domains to PSMA to increase binding to this tumor antigen, and a single, lower affinity binding domain to CD3. The bispecific candidate is designed to induce target-specific T-cell killing of PSMA positive cancer cells while improving concentration of the drug at the tumor site. The drug candidate is built on Aptevo's ADAPTIR-FLEX platform and leverages the unique properties of this technology to increase binding to PSMA while lowering binding to T cells in the circulation. This design has potential to increase the amount of drug concentration at the site of PSMA-positive tumors and increase anti-tumor responses by tumor-infiltrating T cells.
