Research Overview
Plecanatide
Clinical trials show plecanatide improves constipation outcomes with a generally favorable tolerability profile. Like linaclotide, it acts locally in the intestinal lumen via GC-C signaling rather than systemic hormone effects.
IGF-1 LR3
IGF-1 LR3 has extensive in vitro and animal data. Its role in muscle hyperplasia is well-documented. The extended half-life modification provides practical advantages over native IGF-1.
