Results from previous studies:
- The investigational drug lenabasum successfully achieved the primary objective of a Phase 2 study in 22 adults by demonstrating that lenabasum had a mean improvement (reduction) in the primary efficacy outcome, the Cutaneous Dermatomyositis Disease Area and Severity Index (CDASI) activity score was 9.3 points for lenabasum treatment at the end of the study versus a reduction of 3.7 points for placebo treatment (p = 0.04) in patients with skin-predominant dermatomyositis. The most common adverse events were dizziness (45.5% vs 18.2% of lenabasum and placebo subjects) and dry mouth (36.4% vs 9.1% of lenabasum and placebo subjects).

- Corbus received approval for an open-label extension (OLE) to its single center, double-blind, randomized, placebo-controlled Phase 2 clinical study of lenabasum for dermatomyositis from the U.S. Food and Drug Administration (FDA) in November 2016 to collect long term safety and efficacy data on lenabasum. In October 2018, Corbus reported that lenabasum demonstrated continued improvement in subjects with DM. The CDASI activity score improved from study start by a mean of -15.4 points at 6 months to -17.6 points at 12 months. Lenabasum-related AEs occurring in more than 1 subject during chronic dosing was fatigue (n = 2, 10%). To learn more about the study, click:
