New England Journal of Medicine (2025) The REDEFINE 1 Phase 3 trial was a landmark 68-week, double-blind, randomized study comparing CagriSema (cagrilintide 2.4 mg plus semaglutide 2.4 mg) with semaglutide alone, cagrilintide alone, and placebo in 3,417 adults with obesity or overweight without diabetes

Researchers should note this distinction when transitioning between different peptide protocols

This is specific to retatrutide and not typically seen with cagrilintide

But the antimicrobial peptide profiles are dramatically different

Upon reconstitution, liquid stock solutions stored in DMSO or organic vehicles should be divided into single-use aliquots to prevent repeated freeze-thaw cycles, which degrade peptide bonds over time

Not FDA-approved for any therapeutic use
