Corbus Pharmaceuticals stock rises on obesity drug trial data
Corbus Pharmaceuticals (CRBP) shares rose 12% after reporting positive Phase 1b trial data for obesity drug CRB-913. The 60 mg dose showed 5% mean weight loss at 12 weeks. The trial enrolled 254 participants and tested three doses, all showing significant weight loss. The drug was generally well tolerated. Corbus plans to discuss further development with the FDA and start a Phase 2 study in early 2027.
