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.
Anamorelin
Trials in cachexia populations showed increased appetite and modest gains in body weight and IGF-1. Regulatory progress has varied by region, but it remains a well-studied ghrelin agonist in the GH space.
