Roche Exits CT-173 Obesity Program to Refocus on Competitive Portfolio Leaders
SHERIDAN, WYOMING – July 25, 2025 – Roche has officially discontinued development of CT-173, an investigational PYY analog once positioned as a novel obesity treatment, citing a lack of competitiveness and development potential in its latest strategic assessment.
The decision, announced during the company’s second-quarter earnings call, marks a clear pivot in Roche’s prioritization within its obesity drug pipeline, following its high-profile acquisition of Carmot Therapeutics for $2.7 billion in December 2023. The move reflects Roche’s sharpened focus on only the most promising assets as the obesity drug market becomes increasingly competitive.
