§1.3Sequence and structural notes

A non-amyloidogenic amylin analogue engineered for high solubility and weekly administration

Developed on the premise that amylin receptor agonism alone may produce weight reduction with better gastrointestinal tolerability than incretin receptor agonism. The full sequence is not public.

§1.4Assessment status
