Head-to-head evidence
cagrilintide vs petrelintide
Same mechanism, same race: design-graded trial evidence for both assets, with the grading rationale shown. Grades describe the quality of the evidence, never the merits of either security.

cagrilintide
Developed by Novo Nordisk
NCT03856047 · Phase 2 · completed
The trial randomized participants to five active doses, a pooled placebo, and an active liraglutide comparator arm, with quadruple-blinding (participant, care provider, investigator, and outcomes assessor all masked) and roughly 100 participants per arm. The primary endpoint, percent change in body weight at 26 weeks, is the regulator-accepted physiological measure for obesity trials, and every cagrilintide dose showed a statistically significant weight-loss advantage over placebo (p-values ranging from 0.0002 to <.0001), so the primary comparison was clearly met in the favorable direction.
Next expected readout: January 2027 · NCT07411560 (registry estimate)
petrelintide
Developed by Zealand Pharma and partners
NCT06662539 · Phase 2 · completed
The study was randomized and double-blind, used matching placebo, and enrolled 493 participants. Its primary clinical endpoint was change in body weight, but the outcome comparison is not yet available because results have not been posted.
Next expected readout: November 2027 · NCT07589686 (registry estimate)
