Head-to-head evidence
aleniglipron vs orforglipron
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.
Obesity
Shared mechanism: GLP-1 receptor · full Obesity pipeline
aleniglipron
Developed by Structure Therapeutics
NCT06703021 · Phase 2 · completed
The study was randomized, triple-blind, and placebo-controlled, with 85 participants. Registry results were not posted at the time of grading; the key result shown was recovered from the cited external source.
Registered primary outcomes are safety measures; the weight-loss figures are the trial's prespecified efficacy readout, reported in the sponsor's topline press release and not yet peer reviewed. Caveat: this result is taken from a company announcement or a news report of one, not from the trial registry or a peer-reviewed publication. Treat the figures as the sponsor's own statement, not as independently verified evidence.
Next expected readout: September 2028 · NCT07654361 (registry estimate)
orforglipron · Foundayo
Marketed by Eli Lilly
NCT05803421 · Phase 3 · completed
The study is randomized and active-controlled with a large sample of 2,749 participants, but it is open-label rather than blinded. Its primary endpoint is a hard clinical cardiovascular outcome; however, the comparison cannot be judged because no results are currently available.
Next expected readout: February 2027 · NCT06672549 (registry estimate)
Type 2 Diabetes
Shared mechanism: GLP-1 receptor · full Type 2 Diabetes pipeline
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the weight results are the phase 2a obesity cohort's efficacy readout from the sponsor's SEC-filed topline release, not yet peer reviewed.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)
