• Dosing of First Patient in Phase 2a Clinical Trial of DA-1241 Expected September 2023
• Cash and Cash Equivalents of $28.7 Million, Expected to Fund the Company into 2024, Through Multiple Clinical Milestones

BOSTON, Aug. 9, 2023 /PRNewswire/ -- NeuroBo Pharmaceuticals, Inc. (Nasdaq: NRBO), a clinical-stage biotechnology company on a quest to transform cardiometabolic diseases, today announced financial results for the second quarter ended June 30, 2023 and provided a corporate strategic update.

"During the second quarter and thereafter, we have made significant progress advancing the development of our two promising cardiometabolic assets, which address the underserved nonalcoholic steatohepatitis (NASH) market and the significant obesity and type 2 diabetes (T2D) markets," stated Joe Hooker, Interim President and Chief Executive Officer of NeuroBo. "Notably, in May, we received U.S. Food and Drug Administration (FDA) approval of our Investigational New Drug (IND) application for DA-1241, a novel G-Protein-Coupled Receptor 119 (GPR119) agonist, for the treatment of NASH. This was followed, just recently, with receipt of first site Institutional Review Board (IRB) approval for the Phase 2a clinical trial of DA-1241. We look forward to working closely with our contract research organization (CRO) partner and our site investigators, with the goal to dose the first patient next month. We believe that the mechanism of action of DA-1241 will translate into a new and effective treatment for NASH. In preclinical studies, DA-1241 demonstrated a beneficial effect on liver inflammation and fibrosis, lipid metabolism and glucose metabolism, and was shown to be safe and well tolerated in Phase 1a/1b studies in healthy volunteers and patients with T2D. As previously announced, the two-part design will provide optionality for an interim analysis in the first half of 2024, and we anticipate a full data readout in the second half of 2024.

"Additionally, in June, positive preclinical data was presented at the American Diabetes Association's 83rd Scientific Sessions, demonstrating that our second asset, DA-1726, a novel oxyntomodulin (OXM) analogue which acts as a glucagon-like peptide-1 receptor (GLP1R) and glucagon receptor (GCGR) dual agonist, elicits superior weight loss efficacy compared to Semaglutide (SEMA) and Tirzepatide (TIR) and effective glycemic control in mice models. We intend to advance DA-1726 through the IND process during the second half of this year. If accepted by the FDA, we plan to initiate a Phase 1a safety study in the first half of 2024, with a data readout expected in the second half of 2024. Based on the preclinical evidence demonstrating superior body weight loss compared with other selective GLP1R agonists, we are optimistic about the potential of DA-1726 to address the significant obesity market."

Mr. Hooker added, "We have also made progress toward our goal of evaluating potential out-licensing and acquisition opportunities for our four legacy therapeutic programs and recently announced signing of a term sheet with MThera Pharma Co., Ltd. (MTHERA) to out-license the worldwide rights, outside of Korea, for NB-01 for the treatment of painful diabetic neuropathy. With MTHERA's deep knowledge of manufacturing, evaluating the quality of, and researching natural medicines and botanical drugs, we consider it the optimal partner to progress the clinical development of NB-01. Meanwhile, we continue to evaluate potential opportunities for our three remaining legacy therapeutic programs, ANA001, NB-02 and Gemcabene. With a cash cushion of $28.7 million at quarter end to fund operations through multiple, near-term value creating milestones, we are enthusiastic about the potential of our cardiometabolic assets and look forward to continued execution to drive shareholder value."

• June 2023: Presented preclinical data on DA-1726, a novel OXM analogue functioning as a GLP1R and GCGR dual agonist, showing an ability to elicit superior weight loss efficacy compared to SEMA and TIR. Additionally, DA-1276 has shown effective glycemic control. The data was presented in one ePoster theater discussion and two general poster presentations at the American Diabetes Association's 83rd Scientific Sessions.
• May 2023: Appointed Mark A. Glickman, a highly accomplished pharmaceutical industry executive with more than 30 years of industry experience, to the Board of Directors.
• May 2023: Received FDA clearance for the Company's IND application for a two-part, Phase 2a clinical trial of DA-1241 for the treatment of NASH.

Second Quarter 2023 Financial and Operating Results

• Research and Development (R&D) Expenses were approximately $2.4 million for the three months ended June 30, 2023 as compared to approximately $1.0 million for the three months ended June 30, 2022. The approximate $1.4 million increase was primarily related to costs as the Company prepared for the clinical trial of DA-1241, set to begin in the third quarter of 2023, including increases in drug manufacturing and toxicology studies of $0.7 million and $0.6 million, respectively. The increase is also partially attributable to related clinical study and overhead costs in the aggregate of $0.1 million.
  
  For the six months ended June 30, 2023, R&D expenses were approximately $3.0 million, as compared to approximately $1.9 million for the six months ended June 30, 2022.

About NeuroBo Pharmaceuticals

NeuroBo Pharmaceuticals, Inc. is a clinical-stage biotechnology company on a quest to transform cardiometabolic diseases. The company is currently developing DA-1241 for the treatment of Non-Alcoholic Steatohepatitis (NASH) 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, which promotes the release of key gut peptides GLP-1, GIP, and PYY. In preclinical studies, DA-1241 demonstrated 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 acts 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.
