DA-1726 Also Exhibited Superior Glucose Lowering Compared to Survodutide
Lipid-Lowering Effect of DA-1726 Shown to be Superior Compared to Tirzepatide
Data Presented at the ADA 84th Scientific Sessions
CAMBRIDGE, Mass., June 22, 2024 /PRNewswire/ — NeuroBo Pharmaceuticals, Inc. (Nasdaq: NRBO), a clinical-stage biotechnology company focused on the transformation of cardiometabolic diseases, today announced pre-clinical data which indicates that DA-1726, a novel, dual oxyntomodulin (OXM) analog agonist that functions as a glucagon-like peptide-1 receptor (GLP1R) and glucagon receptor (GCGR), demonstrated superiority in weight loss, retention of lean body mass, and lipid-lowering effects compared to survodutide, in pre-clinical models. Tae-Hyoung Kim, Lead research scientist, Dong-A ST Research Center, will present the data today, in a poster at the American Diabetes Association (ADA) 84th Scientific Sessions, taking place June 21-24, in Orlando, Florida.
“The data being presented at the ADA further differentiates DA-1726 from obesity drugs in the same class, potentially due to its GLP-1 and glucagon receptor activity ratio,” stated Hyung Heon Kim, President and Chief Executive Officer of NeuroBo. “DA-1726, in obese mouse models, significantly lowered cholesterol levels and induced superior weight loss, compared to survodutide, a drug with the same mechanism of action, while also exhibiting superior glucose lowering. Most notably, DA-1726 demonstrated superior weight loss and retention of relative lean body mass preservation compared to survodutide. Further, as previously disclosed pre-clinical studies showed, DA-1726 resulted in similar weight reduction while consuming more food compared to tirzepatide and this additional data, being presented at the ADA, in a hypercholesterolemia rat model, confirmed that DA-1726 is more effective than tirzepatide in suppressing cholesterol levels, due to its glucagon action, alongside its GLP-1 effect, while also inhibiting weight gain. We believe these distinguishing factors can potentially position DA-1726 as a best-in-class obesity drug with superior efficacy and better tolerability profile. The Phase 1 trial of DA-1726 is progressing well, and we expect to both dose the first patient in the multiple ascending dose (MAD) Part 2 and read-out top-line data from the single ascending dose (SAD) Part 1 in the third quarter of this year, with top-line data from the MAD Part 2 expected in the first quarter of 2025.”

DA-1726 is currently in a Phase 1 clinical trial. This study focuses on the pharmacological effects of this novel oxyntomodulin analogue, which has been effective at improving lipid profiles and reducing weight in rodent models. In an obese mouse model, DA-1726 showed superior weight loss compared to survodutide (-24.7%, -18.2%; P<0.05 vs. control) while demonstrating superior body fat mass reduction and relative lean body mass preservation versus survodutide (body fat change -31.4%, -15.1% vs. -8.7% control). DA-1726 also significantly lowered T-CHO (-67.7%, -49.6%; P<0.05 vs. control) and TG (-49.5%, -41.2%; P<0.05 vs. control) while showing superior glucose lowering compared to survodutide (-54.7%, -30.4% vs. control; P<0.05). Interestingly, despite the same mechanism of action, DA-1726-treated mice showed superior weight loss, fat mass reduction and glucose lowering efficacy. This effect might stem from DA-1726's GLP-1 and glucagon receptor activity ratio. DA-1726's glucagon action could further enhance energy expenditure (EE), and it is believed to have significantly increased the expression of EE-related genes in brown adipose tissue.
In a prior study, DA-1726 showed a difference in improving lipid levels, despite similar weight loss to tirzepatide. Therefore, the direct lipid-regulating effect of DA-1726 was assessed in a hypercholesterolemia rat model compared with tirzepatide. As a result, DA-1726 was more effective than tirzepatide in suppressing the elevation of T-CHO (-33.5%, -25.5% vs. control; P<0.05) and LDL-C (-53.2%, -41.5% vs. control; P<0.05) despite the two groups of rats consuming the same amount of food. This differentiated impact is thought to arise from DA-1726's glucagon action, alongside its GLP-1 effect. The study evaluated whether these differential effects could also be distinguished from drugs of the same class.
In summary, it was confirmed that DA-1726 has differentiating characteristics in the competition of obesity treatment drugs with similar or identical mechanisms in its effect on improving cholesterol metabolism through glucagon action.

About DA-1726DA-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 and cotadutide (another OXM analogue). Additionally, in pre-clinical mouse models, DA-1726 elicited similar weight reduction, while consuming more food, compared to tirzepatide and survodutide, while also preserving lean body mass and demonstrating lipid-lowering effects compared to survodutide.
About NeuroBo PharmaceuticalsNeuroBo 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 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 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. 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.
