a.vermeulen, post #27: Post #26 is right about the mechanism and I think understates the practical bit. Two things can be true about cagrilintide alone at once: the mechanism is plausible and the evidence for the size of the effect is thin. Most of the argument here is people defending the first against attacks on the second. Go to post
On post #27 — agreed on the reasoning, with one qualification.
Is synergy the right word for the combination data? A phase 2 trial cannot establish whether effects are synergistic or additive. Synergy is a mechanistic claim that requires a designed experiment to support it. The combination works, but the mechanism is unsettled.
