apitegromab vs taldefgrobep alfa
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.

apitegromab
Developed by Scholar Rock
NCT06445075 · Phase 2 · completed
This was a randomized, double-blind, placebo-controlled trial in 102 adults with obesity taking tirzepatide, and apitegromab significantly reduced lean-mass loss compared with placebo (p=0.001). The primary measure was change in lean body mass, a body-composition measure, rather than the total weight loss that defines an obesity treatment's efficacy, so this is supportive evidence of a muscle-preserving effect rather than a direct efficacy readout for obesity.
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.
