Corbus Pharmaceuticals Holdings, Inc. (NASDAQ: CRBP), a clinical-stage company focused on promising new therapies in oncology and obesity, today announced the last patient has been enrolled and completed the first clinical visit (Last Patient First Visit) in the Company's CANYON-1 Phase 1b clinical trial of CRB-913 for the treatment of obesity. The CANYON-1 study is on track to be completed in the summer of 2026. CRB-913 is a once-daily highly peripherally restricted oral CB1 inverse agonist potentially offering an orthogonal approach to weight loss and long-term weight management.

The CANYON-1 Phase 1b clinical trial is a 16-week, double-blind, placebo-controlled, dose-ranging study in 240 obese, non-diabetic participants, and is being conducted at multiple clinical sites in the United States. The trial includes a placebo cohort and three CRB-913 cohorts of 20 mg, 40 mg, and 60 mg dosed orally once-daily (QD). A dose titration regimen is included in the design, with all CRB-913 participants commencing at 20 mg/day and then titrating up to either 40 mg/day or beyond that to 60 mg/day, depending on their respective cohorts. Participants are dosed for 3 months and are then monitored for an additional month post-dosing.
