NeuroBo Pharmaceuticals Inc
says its DA-1726, a novel oxyntomodulin analog functioning as a glucagon-like peptide-1 receptor and glucagon receptor dual agonist, had been shown to elicit superior weight loss efficacy compared to Semaglutide and Tirzepatide in preclinical testing.

Semaglutide is sold under Ozempic, Wegovy and Rybelsus. Tirzepatide is sold under Mounjaro by Eli Lilly And Co .DA-1726 demonstrated weight loss efficacy in diet-induced obese (DIO) rats (32.6% for DA-1726 at a high dose vs. 24.0% for semaglutide, p<0.05).
The low-dose DA-1726 group showed a similar effect compared to semaglutide despite consuming more food. The high-dose DA-1726 group showed similar food intake as SEMA, however, it led to a higher weight-loss effect.
DA-1726 (250 and 500 nmol/kg) induced small but significant weight loss three days after a single injection (-7.6% and -9.5% vs. control).
The pharmacological effect of DA-1726 was evaluated compared to other competitor peptides. DA-1726 showed superior efficacy compared to cotadutide (COTA) in reducing body weight (14.4% for DA-1726 and 6.4% for COTA vs. diet-induced obese (DIO) mice control at 30 nmol/kg, p<0.05) and improving plasma glucose, insulin, and Homeostatic Model Assessment for Insulin Resistance (HOMA-IR) (-91% for DA-1726 vs. -52% for COTA) in DIO mice.
DA-1726 showed superior plasma triglyceride (TG) reduction and a similar reduction of total cholesterol (T-CHO) compared to cotadutide.
Compared with Tirzepatide, DA-1726 showed similar efficacy on weight loss and improved plasma metabolic parameters.
Joe Hooker, Interim President and CEO of NeuroBo, highlighted that DA-1726 is in preclinical development for obesity and NASH, with plans to initiate a phase 1a safety study in 1H of 2024.
