Human evidence
Two peer-reviewed 2026 Phase II trials show significant HbA1c reductions with once-weekly subcutaneous and once-daily oral zenagamtide in type 2 diabetes.
Cagrilintide has randomized Phase II weight-loss evidence and a Phase IIIa monotherapy arm within REDEFINE 1; cagrilintide 2.4 mg weekly produced roughly 11.5%-11.8% mean weight reduction at 68 weeks depending on estimand.
