Overcoming the CRS Barrier: Dual-Masked T-Cell Engager VAR5500 Shows Deep PSA Responses in mCRPC
At a recent major oncology conference, Professor Johann de Bono from the Royal Marsden Hospital presented Abstract 17, detailing the preliminary results of a first-in-human Phase 1 dose-escalation trial. The study evaluated VAR5500, a dual-masked pro-X10 T-cell engager targeting PSMA and CD3, in patients with metastatic castration-resistant prostate cancer (mCRPC). This study provides critical proof-of-concept data for the next generation of precision immunotherapy in solid tumors.
