NeuroBo Pharmaceuticals Announces Positive Top-Line Data From the SAD Part 1 of Its Phase 1 Clinical Trial Evaluating DA-1726 for the Treatment of Obesity
Data Revealed Favorable Safety, Tolerability and Dose-Linear Pharmacokinetics (PK)
Top-Line Data Readout from the MAD Part 2 Expected in the First Quarter of 2025
Planned Phase 1 Part 3 Will Evaluate Early Proof of Concept
CAMBRIDGE, Mass., Sept. 30, 2024 /PRNewswire/ -- NeuroBo Pharmaceuticals, Inc.(Nasdaq: NRBO), a clinical-stage biotechnology company focused on transforming cardiometabolic diseases, today announced positive top-line safety, tolerability, and dose-linear pharmacokinetics (PK) data from the single ascending dose (SAD) Part 1 of its 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.
In the SAD Part 1 of the Phase 1 clinical trial, a total of 45 obese, otherwise healthy participants were randomized in a double-blind, 6:3 ratio of DA-1726 or placebo. Single ascending doses were found to be safe and well tolerated, with no serious adverse events. Only 5 subjects in the DA-1726 treatment group reported adverse events (AEs) compared with 3 subjects in the placebo group. A dose-linear PK profile was observed across the investigated dose range. Additional cohorts are being added to the SAD Part 1 to explore the maximum tolerated dose.
"The safety, tolerability and dose-linear PK data generated from the Part 1 SAD trial are highly encouraging and allowed for the accelerated initiation of our multiple ascending dose (MAD) study," stated Hyung Heon Kim, President and Chief Executive Officer of NeuroBo. "In light of the strong safety profile from the SAD Part 1 of the study, we are in the process of adding one or more cohorts to further explore the maximum tolerated dose, which will allow us to realize the full potential of DA-1726. Based on the preclinical data generated to date, as well as DA-1726's balanced activation of GLP1R and glucagon receptors, which increases energy expenditure, we continue to believe that DA-1726 may become a best-in-class obesity drug with a better tolerability profile than currently marketed GLP-1 agonists, and those now in late-stage clinical trials. We eagerly anticipate reporting top-line data from the MAD Part 2 in the first quarter of 2025, which will give us an early read on clinical efficacy. Additionally, we continue to plan Part 3 of the trial that will explore early proof of concept."
The MAD Part 2 of the Phase 1 trial is a randomized, placebo-controlled, double-blind study to investigate the safety, tolerability, PK, and PD of multiple ascending doses of DA-1726 in obese, otherwise healthy subjects. Part 2 is 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 first patient in the MAD study was dosed ahead of schedule, in late June, as previously reported.
The primary endpoint of the Phase 1 trial is to 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 Metabolic Dysfunction-Associated Steatohepatitis (MASH) that is to be administered once weekly subcutaneously. DA-1726 acts 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 pre-clinical mice models, resulted in improved weight loss compared to semaglutide (Wegovy?) and cotadutide (another OXM analogue). Additionally, in pre-clinical mouse models, DA-1726 elicited similar weight reduction, while consuming more food, compared tirzepatide (Zepbound?) and survodutide (a drug with the same MOA), while also preserving lean body mass and demonstrating improved lipid-lowering effects compared to survodutide.
About NeuroBo Pharmaceuticals NeuroBo Pharmaceuticals, Inc. is a clinical-stage biotechnology company focused on transforming cardiometabolic diseases. The company is currently developing DA-1726 for the treatment of obesity, and is developing DA-1241 for the treatment of Metabolic Dysfunction-Associated Steatohepatitis (MASH). 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. 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 pre-clinical 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.
