CAMBRIDGE, Mass., March 28, 2024 /PRNewswire/ -- NeuroBo Pharmaceuticals, Inc. (Nasdaq: NRBO), a clinical-stage biotechnology company focused on transforming cardiometabolic diseases, today announced financial results for the year ended December 31, 2023 and provided a corporate strategic update.

"Throughout 2023 and into the first quarter of 2024, we made remarkable progress advancing the clinical development of our two, next generation cardiometabolic assets, which address the significant metabolic dysfunction-associated steatohepatitis (MASH) and obesity markets," stated Hyung Heon Kim, President and Chief Executive Officer of NeuroBo. "Most recently, we received Safety Review Committee (SRC) approval, recommending that the Phase 2a clinical trial for DA-1241, a novel G-Protein-Coupled Receptor 119 (GPR119) agonist for treating MASH, continue without modification. The SRC recommendation was based on no significant safety trends found in the first six months of study conduct, which is an early indication of the safety of DA-1241. Pre-clinical safety data, reported in January, showed promising results for DA-1241 in combination with sitagliptin, a DPP4 inhibitor. Enrollment for Part 2 has also begun, indicating a strong commitment to the timely development of our pipeline programs. As previously reported, based on the pre-clinical evidence to date, DA-1241 has been shown to effectively improve hepatic and systemic inflammation, with the sitagliptin combination therapy showing synergistic anti-inflammatory effects. The drug has also been shown to be well tolerated in both healthy volunteers and patients with type 2 diabetes mellitus (T2DM). We continue to believe that DA-1241 has the potential to be a safe and effective treatment for MASH and look forward to reporting full trial data in the second half of this year.

"Our second asset, DA-1726, a novel oxyntomodulin (OXM) analogue acting as a GLP1R and GCGR dual agonist, is currently in preparations for a Phase 1 study for the treatment of obesity. In February of this year, shortly after the U.S. Food and Drug Administration (FDA) cleared our Investigational New Drug (IND) application for the clinical trial, we received our first site Institutional Review Board (IRB) approval to proceed with the Phase 1 clinical trial. Importantly, in preclinical testing, DA-1726 showed superior weight loss compared to semaglutide (Wegovy®), and its administration resulted in similar weight reduction even while consuming more food compared to tirzepatide (Zepbound™). Additionally, DA-1726 has shown improvements in hepatic steatosis, inflammation, and fibrosis. Given this data, we believe DA-1726's balanced combination of reduced food intake and increased energy expenditure can potentially be a safe and effective therapy for obesity. We have begun screening patients with the goal of randomizing the first patient in the second quarter of this year and anticipate reporting top-line data from the single ascending dose (SAD) Part 1 in the first half of 2025, and from the multiple ascending dose (MAD) Part 2 in the second half of 2025."

Mr. Kim concluded, "It is an exciting time at NeuroBo and to add to this, I would like to welcome Marshall Woodworth, who was recently appointed as our permanent Chief Financial Officer. He has already made a significant impact on the company and its financial operations and his continued contributions to the team will be key as we continue to execute on the clinical development of our two promising cardiometabolic assets."

Fourth Quarter 2023 and Subsequent Highlights

• March 2024: Received SRC approval recommending that the two-part Phase 2a trial of DA-1241 for the treatment of MASH continue without modification following a blinded safety review of the first six months of study conduct.
• March 2024: Announced the appointment of Marshall Woodworth as Chief Financial Officer, following his tenure as Acting Chief Financial Officer.

• January 2024: Reported positive pre-clinical safety data of DA-1241 in combination with sitagliptin, a DPP4 inhibitor. The pre-clinical results demonstrated that once daily oral administration in rats, of sitagliptin alone (180 mg/kg/day), DA-1241 alone (100 mg/kg/day), or sitagliptin in combination with DA-1241 (up to 180/100 mg/kg/day sitagliptin+DA-1241) for 13 weeks, was well tolerated with no adverse effects. Additionally, the company announced it had opened enrollment for Part 2 of its Phase 2a clinical trial of DA-1241 when co-administered with sitagliptin for the treatment of MASH.
• December 2023: Effected a 1-for-8 reverse stock split to regain compliance with the Nasdaq minimum bid price requirement. On January 8, 2024, company received notification from Nasdaq that it had regained compliance.
• November 2023: Appointed James P. Tursi, M.D., a pharmaceutical industry veteran, to its Board of Directors and as a member of the Board's Nominating and Governance Committee.

Anticipated Clinical Milestones

• DA-1241 in MASH: Full data from the Phase 2a clinical trial of DA-1241 in MASH is expected to be available in the second half of 2024.
• DA-1726 in Obesity: Initiation of a Phase 1 single ascending dose (SAD) study and multiple ascending dose (MAD) study, expected in the second quarter of 2024. Top-line data from the single ascending dose (SAD) Part 1 is expected in the first half of 2025 and from the multiple ascending dose (MAD) Part 2 in the second half of 2025.

Full Year 2023 Financial and Operating Results

• Research and Development (R&D) Expenses were approximately $9.2 million for the year ended December 31, 2023, as compared to approximately $2.8 million for the year ended December 31, 2022. The increase of approximately $6.4 million was primarily attributable to (i) $6.3 million in higher expenditures for investigational drug manufacturing costs, non-clinical and pre-clinical services, clinical trials and consulting, (ii) $0.1 million in higher stock-based compensation, and (iii) $0.1 million in higher employee compensation and benefits.
  
  
• General and Administrative Expenses were approximately $6.7 million for the year ended December 31, 2023, compared to approximately $8.6 million for the year ended December 31, 2022. The decrease of approximately $1.9 million was primarily due to (i) $0.9 million in lower insurance cost, (ii) $0.7 million in lower stock-based compensation, (iii) $0.3 million in lower legal and professional fees, and (iv) $0.3 million in lower employee compensation and benefits. The decreases were partially offset by an increase of $0.2 million in state non-income taxes and fees as well as public company costs.
  
  
• Total Operating Expenses were approximately $15.9 million for the year ended December 31, 2023, compared to approximately $19.6 million for the year ended December 31, 2022. The approximately $3.7 million decrease was primarily attributable to (i) $8.2 million in lower acquired in-process R&D expenses and (ii) $1.9 million in lower general and administrative expenses. The decreases were partially offset by $6.4 million in higher R&D expenses.
  
  
• Other Income was approximately $3.4 million for the year ended December 31, 2023, compared to approximately $5.7 million for the year ended December 31, 2022. The decrease was primarily attributable to a decrease of $5.0 million in gain related to the change in fair value of warrant liabilities. The decrease was partially offset by $0.5 million of interest income recorded in 2023 and $2.3 million of financing and other expenses incurred in 2022.
  
  
• Net Loss for the year ended December 31, 2023, was $12.5 million, or $2.46 per basic and diluted share, based on 5,071,101 weighted average shares of common stock outstanding, compared with a net loss of $14.0 million, or $43.42 per basic and diluted share, based on 321,703 weighted average shares of common stock outstanding for the year ended December 31, 2022.
  
  
• Cash was $22.4 million as of December 31, 2023, compared with $33.4 million as of December 31, 2022. The company expects its cash position will be adequate to fund operations into the fourth quarter of 2024.

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.
