First Patient Expected to be Randomized in the Second Quarter of 2024

CAMBRIDGE, Mass., Feb. 29, 2024 /PRNewswire/ -- NeuroBo Pharmaceuticals, Inc. (Nasdaq: NRBO), a clinical-stage biotechnology company focused on transforming cardiometabolic diseases, today announced that it has received first site Institutional Review Board (IRB) approval for Alexander Prezioso, M.D., Investigator, Clinical Pharmacology of Miami, in Hialeah, FL, to proceed with the Phase 1 clinical trial of DA-1726, a novel, dual oxyntomodulin (OXM) analog agonist that functions as a glucagon-like peptide-1 receptor (GLP1R) and glucagon receptor (GCGR), for the treatment of obesity. The company expects to randomize the first patient in the second quarter of this year.

"With this first site IRB approval, we have achieved another significant milestone in the development of DA-1726, bringing the program one step closer to the clinic," stated Hyung Heon Kim, President and Chief Executive Officer of NeuroBo. "This promising cardiometabolic asset may have a better tolerability profile than currently available GLP-1 agonists due to its balanced activation of GLP1R and glucagon receptors. As previously reported, in mouse models, DA-1726 showed superior weight loss compared to semaglutide (Wegovy), and its administration resulted in similar weight reduction while consuming more food compared to tirzepatide (Zepbound). We look forward to working closely with our contract research organization (CRO) partner and our investigators, such as Dr. Prezioso, to start randomizing patients in the second quarter of this year. We expect to report top-line data from the single ascending dose (SAD) Part 1 in the first half of 2025 and the multiple ascending dose (MAD) Part 2 in the second half of 2025."

The Phase 1 trial is designed to be a randomized, placebo-controlled, double-blind, two-part study to investigate the safety, tolerability, pharmacokinetics (PK), and pharmacodynamics (PD) of single and multiple ascending doses of DA-1726 in obese, otherwise healthy subjects. Part 1 will be a single ascending dose (SAD) study, expected to enroll approximately 45 participants, randomized into one of 5 planned cohorts. Each cohort will be randomized in a 6:3 ratio of DA-1726 or placebo. Part 2 will be a multiple ascending dose (MAD) study, expected to enroll approximately 36 participants, who will be randomized at the same 6:3 ratio into 4 planned cohorts, each to receive 4 weekly administrations of DA-1726 or placebo.

The primary endpoint will assess the safety and tolerability of DA-1726 by monitoring adverse events (AEs), serious adverse events (SAEs), treatment emergent adverse events (TEAEs) and AEs leading to treatment discontinuation. Secondary endpoints include the PK of DA-1726, assessed via serum concentrations over time and metabolite profiling at the highest doses of DA-1726. Exploratory endpoints will include the effect of DA-1726 on metabolic parameters, cardiac parameters, fasting lipid levels, body weight, waist circumference and body mass index (BMI), among others.

About DA-1726

DA-1726 is a novel oxyntomodulin (OXM) analogue functioning as a GLP1R/GCGR dual agonist for the treatment of obesity and NASH that is to be administered once weekly subcutaneously. DA-1726 as a dual agonist of GLP-1 receptors (GLP1R) and glucagon receptors (GCGR), leading to weight loss through reduced appetite and increased energy expenditure. DA-1726 has a well understood mechanism and, in preclinical mice models, resulted in improved weight loss compared to semaglutide and cotadutide (another OXM analogue).

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.
