Historically, progression-free survival (PFS) hovers around 7 months and overall survival (OS) around 14 to 16 months. However, depending on the dose, PFS with CMG901 ranged from 3.3 to 14.5 months, and OS ranged from 8.5 months to not reached, after a median follow up of 6 months.
CMG901 was well-tolerated with preliminary promising clinical efficacy in patients with CLDN18.2-positive gastric/GEJ cancer. The Phase 1b dose-expansion trial in gastric/GEJ adenocarcinoma, pancreatic cancer, and other solid tumors is rapidly enrolling, with multiple pivotal (Phases 2 and 3) trials planned. Clinical trial information: NCT04805307.
