Clinical Trials

Clinical trial tracker: peptide and GLP-1 programs to watch in late 2026

Phase 3 readouts, new obesity candidates, and the muscle-preservation programs entering the clinic.

The second half of 2026 is unusually dense with readouts. Retatrutide’s TRIUMPH program leads the calendar, followed by next-generation oral GLP-1 candidates and the first phase 2 data for myostatin-pathway combinations aimed at preserving lean mass during incretin therapy.

This tracker page is updated as programs report; each entry links to the underlying registry record and our related coverage.
