CAMBRIDGE, Mass., Nov. 7, 2024 /PRNewswire/ -- NeuroBo Pharmaceuticals, Inc. (Nasdaq: NRBO), a clinical-stage biotechnology company focused on transforming cardiometabolic diseases, today announced financial results for the third quarter ended September 30, 2024 and provided a corporate update.

"The third quarter was punctuated by the positive top-line results from the single ascending dose (SAD) Part 1 of our 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, revealing it to be safe and tolerable as well as demonstrating dose-linear pharmacokinetics (PK)," stated Hyung Heon Kim, President and Chief Executive Officer of NeuroBo. "Based on the excellent safety data from the SAD Part 1, we are currently engaged in the addition of one or more cohorts to further investigate the maximum tolerated dose, enabling us to fully harness the potential of DA-1726. Based on the pre-clinical data available, along with DA-1726's balanced activation of GLP1R and glucagon receptors, which enhances energy expenditure, we maintain our belief that it can emerge as a best-in-class obesity treatment, offering a more favorable tolerability profile compared to existing GLP-1 agonists and those in late-stage clinical trials. Importantly, the drug's strong safety profile also enabled the accelerated initiation of the multiple ascending dose (MAD) study, for which we expect to report top-line results from the planned cohorts during the first quarter of 2025.

"To further differentiate DA-1726, early in the quarter, we signed a joint research agreement, together with our collaboration partner, Dong-A ST and ImmunoForge, to develop a long-acting once monthly formulation of the drug. Additionally, we continue to plan for an early proof-of-concept, multicenter, randomized, double-blind, placebo-controlled Part 3 of the Phase 1 clinical trial to evaluate the efficacy and safety of DA-1726 in obese, otherwise healthy subjects, reflecting our strong commitment to rapidly advancing the clinical development of this promising cardiometabolic asset. Part 3 is anticipated to begin upon the completion of Part 2."

Mr. Kim continued, "After recently announcing the last patient last visit in our Phase 2a clinical trial for DA-1241, a novel G-Protein-Coupled Receptor 119 (GPR119) agonist, in subjects with presumed metabolic dysfunction-associated steatohepatitis (MASH), our next clinical milestone is the full data readout expected in December of this year. As a reminder, the trial is exploring the efficacy of DA-1241 independently, as well as in combination with sitagliptin, a DPP-4 inhibitor, which we believe will show synergistic effects compared to DA-1241, alone. Based on pre-clinical and clinical evidence generated to date, we continue to believe that DA-1241 has the potential to be a safe and effective treatment for MASH."

Third Quarter 2024 and Subsequent Highlights

• November 2024: Completed the last patient last visit in its two-part, Phase 2a clinical trial evaluating the efficacy and safety of DA-1241 for the treatment of MASH.
• September 2024: Announced positive top-line safety, tolerability and dose-linear PK data from the SAD Part 1 of its Phase 1 clinical trial evaluating DA-1726 for the treatment of obesity. 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 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.
• August 2024: Completed enrollment in the SAD Part 1 of the Phase 1 clinical trial evaluating DA-1726 for the treatment of obesity.
• August 2024: Signed a joint research agreement, along with Dong-A ST and ImmunoForge, to develop a long-acting, once-monthly, formulation of DA-1726 utilizing ImmunoForge's long-lasting half-life extension Elastin-Like Polypeptide (ELP) platform technology.
• July 2024: Signed an exclusive out-license agreement, providing MThera Pharma Co., Ltd. (MTHERA) with the rights to develop and commercialize NB-01, one of the Company's four legacy assets, for the treatment of painful diabetic neuropathy, allowing MTHERA to conduct research and clinical trials, including, but not limited to, a potential Phase 3 clinical trial in the United States and South Korea, for the future commercialization of NB-01.
• July 2024: Engaged veteran biotech and pharmaceutical professional, Chris Fang, MD, as Advisor/Consulting Chief Medical Officer, effective July, 2, 2024.

Anticipated Clinical Milestones

• DA-1726 in Obesity: The last patient visit in the multiple ascending dose (MAD) study Part 2 is expected in the fourth quarter of 2024 and top-line data is expected in the first quarter of 2025. The planned Phase 1 Part 3 will evaluate early proof of concept, with the first patient expected to be enrolled during the third quarter of 2025, followed by an interim data readout in or around mid-2026 and top-line results are expected in the second half of 2026.
• DA-1241 in MASH: Top-line results from the two-part Phase 2a clinical trial of DA-1241 in MASH are expected to be available in December of 2024.

Third Quarter Financial and Operating Results

• Research and Development (R&D) Expenses were approximately $4.5 million for the three months ended September 30, 2024, as compared to approximately $2.3 million for the three months ended September 30, 2023. The increase of approximately $2.2 million was primarily related to increased R&D activities for DA-1241 and DA-1726 for the three months ended September 30, 2024 related to the Phase 2a clinical trial for DA-1241 and Phase 1 trial for DA-1726. Specifically, the $2.2 million increase in R&D expenses was attributable to (i) $1.9 million in higher expenditures for clinical trials, non-clinical and preclinical services, and consulting and (ii) $0.3 million in higher employee compensation and benefits. Included in R&D expenses for the three months ended September 30, 2024 was $0.7 million of non-clinical and preclinical expenses incurred under the Shared Services Agreement with Dong-A ST as compared to $0.4 million for the three months ended September 30, 2023.
  
  R&D expenses were approximately $17.5 million for the nine months ended September 30, 2024, as compared to approximately $5.3 million for the nine months ended September 30, 2023.

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.
