Results from previous studies:

  • The investigational drug lenabasum successfully achieved the primary objective of a Phase 2 study in 43 adults by demonstrating an acceptable safety and tolerability profile at all doses with no serious or severe adverse events related to the study drug. Lenabasum outperformed placebo in the American College of Rheumatology (ACR) Combined Response Index in diffuse cutaneous Systemic Sclerosis (CRISS) score, reaching 33% at week 16, versus 0% for placebo. The most common adverse events were dizziness (22% vs 13% for lenabasum- vs. placebo-treated subjects) and fatigue (19% vs 7% for lenabasum- vs. placebo-treated subjects).

  • Corbus received approval for an open-label extension to its double-blind, placebo-controlled, randomized Phase 2 clinical study of lenabasum for systemic sclerosis from the U.S. Food and Drug Administration (FDA) in April 2016 to collect long term safety and efficacy data on lenabasum. In October 2018, Corbus reported that lenabasum demonstrated a clinically meaningful reduction in modified Rodnan skin score (mRSS) reaching -8.4 points at 6 months, -9.8 points at 12 months, and -10.7 points at 18 months, and an ACR CRISS of 65% at 6 months to 77% at 12 months, then 99% at 18 months. Lenabasum-related AEs occurring in more than 1 subject during chronic dosing was dizziness (n = 2, 6%). To learn more about the study, click:
