Novo Nordisk, Roche, and Terns Pharmaceuticals presented data on their oral obesity candidates at the European Association for the Study of Diabetes meeting, showing weight loss figures of 4%, 4.9%, and 6.1% respectively. Roche's CT-996 led in efficacy but had high adverse event rates, while Novo's amycretin faced manufacturing challenges. Terns' TERN-601 showed potential for high efficacy and tolerability, though it requires further Phase II data.
