hot take: the amylin analogs are more interesting than a fourth receptor
Amylin is co-secreted with insulin and has its own role in satiety and gastric emptying. Analogs are being developed alone and combined with GLP-1 agents.
Why I think it's underrated: the mechanism is complementary rather than overlapping. Two agents hitting the same pathway harder gets you diminishing returns and worse tolerability. Agents on genuinely different pathways is where combination pharmacology usually pays off.
All investigational, some phase 2 combination data published, nothing approved.
I'd expect this to be more interesting than bolting a fourth receptor onto an agonist. Opinion not prediction. Change my mind.
