NeuroBo Pharmaceuticals, Inc. announced that it has received first site Institutional Review Board (IRB) approval for Alexander Prezioso, M.D., Investigator, Clinical Pharmacology of Miami, in Hialeah, FL, to proceed with the 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. The company expects to randomize the first patient in the second quarter of this year. The Phase 1 trial is designed to be a randomized, placebo-controlled, double-blind, two-part study to investigate the safety, tolerability, pharmacokinetics (PK), and pharmacodynamics (PD) of single and multiple ascending doses of DA-1726 in obese, otherwise healthy subjects.

Part 1 will be a single ascending dose (SAD) study, expected to enroll approximately 45 participants, randomized into one of 5 planned cohorts. Each cohort will be randomized in a 6:3 ratio of DA-1726 or placebo. Part 2 will be a multiple ascending dose (MAD) study, expected to enroll approximately 36 participants, who will be randomized at the same 6:3 ratio into 4 planned cohorts, each to receive 4 weekly administrations of DA-1726 or placebo.

The primary endpoint will assess the safety and tolerability of DA-1726 by monitoring adverse events (AEs), serious adverse events (SAEs), treatment emergent adverse events (TEAEs) and AEs leading to treatment discontinuation. Secondary endpoints include the PK of DA-1726, assessed via serum concentrations over time and metabolite profiling at the highest doses of DA-1726. Exploratory endpoints will include the effect of DA-1726 on metabolic parameters, cardiac parameters, fasting lipid levels, body weight, waist circumference and body mass index (BMI), among others.
