Head-to-head evidence
aleniglipron vs PB-119
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.

aleniglipron
Developed by Structure Therapeutics
NCT05762471 · Phase 1/2 · completed
The study randomized 142 participants to GSBR-1290 or placebo with participants, care providers, and investigators masked. Registry results were not posted at the time of grading; the key result shown was recovered from the cited external source.
Registered primary endpoint is safety/tolerability; the weight results are the phase 2a obesity cohort's efficacy readout from the sponsor's SEC-filed topline release, not yet peer reviewed.
Next expected readout: September 2028 · NCT07654374 (registry estimate)
PB-119
Developed by PegBio
NCT04504396 · Phase 3 · completed
This randomized, placebo-controlled trial kept participants, care providers, investigators and outcome assessors blind to treatment assignment. Its primary endpoint, change in HbA1c, was clearly met, with PB-119 producing a significantly larger reduction than placebo (P<0.001).
