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.
Oxyntomodulin
Human studies showed acute reductions in food intake and modest weight loss, helping establish the GLP-1 and glucagon co-agonism concept. It remains a foundational peptide for obesity and satiety research.
