• PD-1 x VEGF antibodies show potential to surpass checkpoint inhibitors as standard-of-care in multiple oncology indications • NAYA aiming to initiate clinical trials in early 2026 Jan. 06, 2025 -- NAYA Biosciences (“NAYA”) (NASDAQ: NAYA), a life science portfolio company dedicated to bringing breakthrough treatments to patients in oncology, autoimmune diseases, and women’s health, today announced that it is expanding its bifunctional antibody pipeline to include a novel PD-1 x VEGF tetravalent bifunctional antibody for the treatment of hepatocellular carcinoma (HCC) and other solid tumors. NAYA is leveraging its proprietary FLEX antibody platform and further optimizing its design through a partnership with MabSilico, an artificial intelligence & deep technology-focused company, to accelerate the development of new best-in-class candidates for validated therapeutic targets. “We are excited to add a novel, AI-optimized PD-1 x VEGF therapeutic candidate to our pipeline of best-in-class bifunctional antibodies,” commented NAYA Biosciences President Dr. Daniel Teper. “NAYA’s bifunctional format has demonstrated the ability for synergistic dual-targeting activity, resulting in the potential to unlock clinical response in solid tumors. NY-500, our PD-1 x VEGF antibody, will target hepatocellular carcinoma (HCC) and other solid tumors with high unmet medical needs. Recent clinical data with ivonescimab, the most advanced PD-1 x VEGF antibody, has shown superiority in non-small-cell lung cancer (NSCLC) compared to Keytruda®, the leading first-line immunotherapy standard-of-care in multiple solid tumors, paving the way for a new generation of PD-(L)1 therapeutic candidates.” NAYA is also developing a GPC3-targeting bifunctional antibody (NY-303) in a phase 1/2 clinical trial for HCC patients not responding to PD-1 +/- VEGF therapy. NAYA has recently presented data for NY-303 at the Society for Immunotherapy of Cancer (SITC) demonstrating the ability to reverse resistance to PD-1 checkpoint blockage and turn tumors from a “cold” into a “hot” status, making the tumors susceptible to immunotherapy again. Initiation of monotherapy Phase 1/2a clinical trials has been cleared by regulatory authorities and leading academic centers and is expected to start in 2025. NY-500 is a tetravalent bifunctional antibody targeting PD-1, a key immune checkpoint targeted by pembrolizumab (Keytruda®, Merck & Co), and VEGF, a vascular endothelial growth factor targeted by bevacizumab (Avastin®, Genentech Roche) which regulates the production of new blood vessels (angiogenesis). Synergistic effects of simultaneously targeting PD-1 & VEGF have been shown to improve T-cell infiltration into tumors and enhance immune response while disrupting tumor vasculature. Ivonescimab, a PD-1 x VEGF antibody from Summit Therapeutics, recently outperformed pembrolizumab in a head-to-head lung cancer clinical trials. NY-500 has a differentiated molecular design, leveraging both NAYA’s proprietary FLEX format and AI-optimization, and is expected to enter monotherapy phase 1/2a clinical trials in early 2026 for the treatment of hepatocellular carcinoma (HCC) & other solid tumors. According to IQVIA, the PD(L)1 market is expected to exceed $50 billion in 2025. NAYA Biosciences (NASDAQ: NAYA) is a life science portfolio company dedicated to bringing breakthrough treatments to patients in oncology, autoimmune diseases, and women’s health. Our proven hub & spoke model harnesses the shared resources of a parent company and agility of lean strategic franchises, enabling efficient acquisition, development, and partnering of assets and allowing for optimized return on investment by combining scalable, profitable commercial revenues with the upside of innovative clinical-stage therapeutics. NAYA’s expanding portfolio of assets currently includes NY-303, a GPC3 x NKp46 bifunctional antibody for the treatment of hepatocellular carcinoma (HCC) with a unique mode of action targeting non-responders to the current immunotherapy standard of care (approximately 70% of the current treatable market) cleared to enroll patients in a Phase 1/2a monotherapy trial in 2025, NY-338, a CD38 x NKp46 bifunctional antibody for the treatment of multiple myeloma and autoimmune diseases with a differentiated safety and efficacy profile, NY-500, a PD-1 x VEGF bifunctional antibody for the treatment of HCC and other solid tumors, and NY-600 a PSMA x NKp46 bifunctional antibody for the treatment of metastatic Castration Resistant Prostate Cancer (mCRPC).
