Business Context and Reporting Period
Corbus Pharmaceuticals Holdings, Inc. (CRBP) filed this Form 8-K on November 10, 2020, to disclose financial results for the fiscal quarter ended September 30, 2020, and to present additional data from its RESOLVE-1 Phase 3 clinical study of lenabasum for systemic sclerosis.
Key Financial Metrics
The filing text references a press release (Exhibit 99.1) containing specific financial information for the quarter ended September 30, 2020, but does not explicitly state revenue, profit, cash flow, margins, debt, or liquidity figures within the body of this 8-K document.
Material Changes and Clinical Data
The primary material update concerns the RESOLVE-1 Phase 3 study of lenabasum for systemic sclerosis (n=363). Key findings include:
- Primary Endpoint: Median ACR CRISS scores at Week 52 were 0.888 for lenabasum versus 0.887 for placebo, indicating no statistically significant difference in the overall population.
- Placebo Effect: Unprecedented improvement was observed in the placebo group, particularly among subjects on background immunosuppressant therapies (84% of subjects) for less than two years.
- Post-Hoc Analysis (Long-term Therapy): In subjects on background immunosuppressants for >2 years, lenabasum showed reduced decline in Forced Vital Capacity (FVC) compared to placebo (-21 mL vs -170 mL; nominal P=0.048).
- Interstitial Lung Disease (ILD) Subset: In subjects with ILD, lenabasum was associated with numerically reduced FVC decline (-14 mL vs -121 mL).
- Safety: Lenabasum was well tolerated with no new safety findings. Adverse events occurring in ≥3% more subjects on lenabasum included dizziness (18.3% vs 4.9%) and dry mouth (5.0% vs 1.6%).
