NeuroBo Pharmaceuticals, Inc. announced the completion of enrollment of Part 1 of its two-part, Phase 2a clinical trial evaluating the efficacy and safety, of DA-1241, a novel G-Protein-Coupled Receptor 119 (GPR119) agonist for the treatment of metabolic dysfunction-associated steatohepatitis (MASH). Approximately 49 patients with presumed MASH have been randomized into Part 1 with a 1:2:1 ratio into 3 treatment groups: DA-1241 50 mg, DA-1241 100 mg, or placebo. Each of the two-parts of the Phase 2a trial of DA-1241 are designed to be 16-week, multicenter, randomized, double-blind, placebo-controlled, parallel clinical studies to evaluate the efficacy and safety of DA-1241 in subjects with presumed MASH.

Part 2, which will explore the efficacy of DA-1241 in combination with sitagliptin versus placebo, is expected to enroll approximately 37 subjects who will be randomized in a 2:1 ratio into 2 treatment groups: DA-1241 100 mg/sitagliptin 100 mg or placebo. For both Part 1 and Part 2, the primary endpoint is the change from baseline in alanine transaminase (ALT) levels at Week 16. Secondary efficacy endpoints include the proportion of subjects with normalization of ALT, absolute change in total cholesterol, low and high-density lipoprotein cholesterol, triglycerides, and free fatty acids from baseline, among others.

Safety will be evaluated by monitoring adverse events (AEs) and serious adverse events (SAEs) leading to discontinuation and laboratory abnormalities.
