VERAXA Biotech (VRXA) Advances FDA-Aligned Methods to Reduce Animal Testing

LOS ANGELES, CA - October 7, 2026 (NEWMEDIAWIRE) - VERAXA Biotech (NASDAQ: VRXA), a developer of next-generation antibody-based cancer therapies, provided an update on its strategy to implement U.S. Food and Drug Administration “FDA”-aligned New Approach Methodologies “NAMs” across its preclinical research and development programs. The company said the approach could accelerate clinical advancement, reduce development costs and timelines and significantly reduce animal testing. VERAXA has built a panel of NAMs to characterize and de-risk its pipeline of BiTAC-based T cell engagers, antibody-drug conjugates and bispecific antibody-drug conjugates.

VERAXA said its lead BiTAC-TCE and bsADC candidates were also evaluated using an ex vivo panel of 10 low-passage patient-derived xenograft models of non-small cell lung cancer. The panel required about 10 mice in total, compared with an estimated 200 or more for comparable in vivo efficacy studies. Across the panel, the combined BiTAC consistently induced potent T cell-mediated killing, supporting the company’s dual-targeting approach and demonstrating how its NAM strategy can reduce animal use and preclinical cycle time without compromising clinical relevance.
