NeuroBo Pharmaceuticals Receives Safety Review Committee Approval to Continue With Its Phase 2a Clinical Trial Evaluating DA-1241 for the Treatment of MASH

Blinded Safety Review Completed for the First 6 Months of the Phase 2a Clinical Trial Conduct; Recommending Trial Continue Without Modification

Full Data Readout Expected in the Second Half of 2024

CAMBRIDGE, Mass., March 13, 2024 /PRNewswire/ -- NeuroBo Pharmaceuticals, Inc. (Nasdaq: NRBO), a clinical-stage biotechnology company focused on transforming cardiometabolic diseases, today announced receipt of Safety Review Committee (SRC) approval, recommending that the two-part Phase 2a trial of DA-1241, a novel G-Protein-Coupled Receptor 119 (GPR119) agonist for the treatment of metabolic dysfunction-associated steatohepatitis (MASH), continue without modification following a blinded safety review of the first six months of study conduct. The Phase 2a clinical trial is designed to evaluate the efficacy and safety of DA-1241, for the treatment of MASH. The company anticipates a full data readout from the trial in the second half of 2024.

"The SRC's recommendation that the trial continue without modification based on no findings of significant adverse safety trends during the first six months of study conduct, is an early indication of the safety of our most advanced cardiometabolic asset, DA-1241, for patients with presumed MASH, a disease with no currently approved treatment options," stated Hyung Heon Kim, President and Chief Executive Officer of NeuroBo. "Based on the pre-clinical and clinical evidence generated to date, DA-1241 has demonstrated reduced hepatic steatosis, hepatic inflammation and liver fibrosis, while also improving glucose control, and was shown to be well tolerated in both healthy volunteers and in patients with type 2 diabetes mellitus (T2DM). We continue to believe that the mechanism of action of DA-1241 will translate into a safe and effective treatment for MASH and look forward to another blinded SRC analysis once the first 50% of patients have been randomized and dosed."

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 1 is exploring the efficacy of DA-1241 versus placebo, and is expected to enroll 49 subjects, with a planned maximum of 55 subjects to account for early discontinuations. Subjects will be randomized in a 1:2:1 ratio into 3 treatment groups: DA-1241 50 mg, DA-1241 100 mg, or placebo. 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), serious adverse events (SAEs) and AEs leading to discontinuation and laboratory abnormalities.

About DA-1241
DA-1241 is a novel G-Protein-Coupled Receptor 119 (GPR119) agonist with development optionality as a standalone and/or combination therapy for both MASH and T2DM. In preclinical studies, DA-1241 demonstrated that GPR-119 agonism promotes the release of the key gut peptides GLP-1, GIP, and PYY, which have a beneficial effect on liver inflammation, lipid metabolism, weight loss, and glucose metabolism. The therapeutic potential of DA-1241 has been demonstrated in multiple pre-clinical animal models of MASH and T2DM whereby DA-1241 reduced hepatic steatosis, hepatic inflammation, and liver fibrosis, while also improving glucose control. Furthermore, in Phase 1a and 1b trials, DA-1241 was well tolerated in both healthy volunteers and those with T2DM.

About NeuroBo Pharmaceuticals
NeuroBo Pharmaceuticals, Inc. is a clinical-stage biotechnology company focused on transforming cardiometabolic diseases. The company is currently developing DA-1241 for the treatment of Metabolic Dysfunction-Associated Steatohepatitis (MASH) and Type 2 Diabetes Mellitus (T2DM), and is developing DA-1726 for the treatment of obesity. DA-1241 is a novel G-protein-coupled receptor 119 (GPR119) agonist that promotes the release of key gut peptides GLP-1, GIP, and PYY. In preclinical studies, DA-1241 demonstrated a positive effect on liver inflammation, lipid metabolism, weight loss, and glucose metabolism, reducing hepatic steatosis, hepatic inflammation, and liver fibrosis, while also improving glucose control. DA-1726 is a novel oxyntomodulin (OXM) analogue that functions as a glucagon-like peptide-1 receptor (GLP1R) and glucagon receptor (GCGR) dual agonist. OXM is a naturally-occurring gut hormone that activates GLP1R and GCGR, thereby decreasing food intake while increasing energy expenditure, thus potentially resulting in superior body weight loss compared to selective GLP1R agonists.
