Summary
Brief summary
DR10624 is an Fc fusion protein tri-agonist with balanced glucagon-like peptide-1 receptor
(GLP-1R)/glucagon receptor (GCGR)/ fibroblast growth factor 21 receptor (FGF21R) agonizing
activities. The objectives of the planned clinical investigation will be to evaluate the
safety, tolerability, pharmacokinetics (PK), and pharmacodynamics (PD) of single- and
multiple-ascending doses of DR10624 via subcutaneous (SubQ) injection in a randomized,
placebo-controlled, double-blind study.
