Corbus Shares Drop After Initial Results for Oral Obesity Treatment CRB-913
Corbus Pharmaceuticals Phase 1 Study Results: Corbus (CRBP) shares fell approximately 3% after reporting results from its phase 1 study of CRB-913, an oral treatment for chronic obesity, which included both single and multiple ascending dose cohorts.
Efficacy and Safety Findings: The multiple ascending dose cohort of obese patients experienced a mean placebo-adjusted weight loss of 2.9% by day 14, with the drug being well tolerated and no serious adverse events reported, although mild anxiety and irritability were noted in some patients.
Market Reaction and Financial Updates: Corbus's stock price dropped 17% following a $75 million fundraising effort priced at $13 per share, alongside a GAAP EPS loss of -$1.90, which missed expectations by $0.16.
Ongoing Developments: The company continues to focus on its drug development efforts, with discussions around data updates and insights from other studies, including those related to head and neck cancer.
Corbus Pharmaceuticals' CRB-913 Achieves 2.9% Weight Loss in Obese Patients
- Clinical Trial Success: Corbus has completed the single ascending dose (SAD) and multiple ascending dose (MAD) Phase 1a studies of CRB-913, with all doses being safe and well-tolerated, and no serious adverse events reported, indicating a strong safety profile.
- Significant Weight Loss Effect: In the 150 mg cohort, all CRB-913-treated participants (n=9) achieved a mean weight loss of 2.9% by Day 14, while none in the placebo group (n=3) lost weight, highlighting the drug's potential in obesity management.
- Follow-up Research Plans: Corbus has initiated the 12-week Phase 1b CANYON-1 study, targeting 240 obese, non-diabetic participants, with completion expected in summer 2026, to further validate the efficacy of CRB-913.
- Broad Market Potential: As a peripherally restricted CB1 inverse agonist with reduced brain penetration, CRB-913 may offer a new treatment option for obesity, particularly when used in combination with existing therapies, presenting significant market opportunities.
