Eli Lilly to unveil new obesity‑treatment data at ObesityWeek 2026

Eli Lilly will present Phase 2 and Phase 3 results for its obesity pipeline at ObesityWeek 2026 in Washington, D.C. The EloraTZP combo achieved an average 54.1‑lb (23.3%) weight loss and a 2.9‑point A1C drop after 48 weeks in participants with obesity or overweight and type 2 diabetes. Retatrutide cut obstructive sleep‑apnea events by up to 60.6% and lowered knee‑osteoarthritis pain by up to 73.1% in its Phase 3 TRIUMPH trials. Real‑world surveys showed Foundayo was rated simple to use and eloralintide reduced food cravings and alcohol intake.

The data suggest Lilly’s investigational drugs could expand treatment options for obesity‑related conditions, potentially driving future sales growth if regulatory approval follows. Investors should watch for any FDA filing updates or commercial launch plans that may affect Lilly’s revenue outlook.
