Head-to-head evidence
ribupatide vs tirzepatide
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/GIP receptor (dual) · full Obesity pipeline
ribupatide
Developed by Kailera Therapeutics under a licence from Jiangsu Hengrui Pharmaceuticals
NCT06396429 · Phase 3 · completed
This was a randomized, quadruple-blind, placebo-controlled trial with 567 participants. The sponsor reports weight loss of up to 17.7% with ribupatide, 16.3 percentage points more than placebo, with up to 88.0% of treated participants losing at least 5% of body weight, and describes the trial as positive.
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: December 2026 · NCT06994650 (registry estimate)
tirzepatide · Zepbound / Mounjaro
Marketed by Eli Lilly
NCT04184622 · Phase 3 · completed
This was a large randomized, double-blind, placebo-controlled trial in 2,539 participants using percent change in body weight, the disease-defining endpoint for obesity, as the primary measure. All three tirzepatide doses produced significantly greater weight loss than placebo at 72 weeks.
Next expected readout: November 2026 · NCT07299084 (registry estimate)
Type 2 Diabetes
Shared mechanism: GLP-1/GIP receptor (dual) · full Type 2 Diabetes pipeline
ribupatide
Developed by Kailera Therapeutics under a licence from Jiangsu Hengrui Pharmaceuticals
NCT06649344 · Phase 3 · completed
Randomized, open-label phase 3 comparing once-weekly ribupatide against semaglutide as add-on to metformin in type 2 diabetes (884 participants). The design is randomized and actively controlled but unblinded. Registry results were not posted at the time of grading; the key result shown was recovered from the cited external source.
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: February 2027 · NCT07060456 (registry estimate)
tirzepatide · Zepbound / Mounjaro
Marketed by Eli Lilly
NCT03730662 · Phase 3 · completed
The study randomized 2,002 participants to tirzepatide or active insulin glargine control, but treatment was open-label rather than blinded. The primary endpoint was change in HbA1c, a laboratory surrogate rather than a hard clinical outcome; although the primary comparisons were statistically significant in favor of tirzepatide, this supports a moderate evidence grade.
Next expected readout: November 2026 · NCT07299084 (registry estimate)
