Lilly's Foundayo Pill Matched Insulin on Heart Safety in Lancet Trial, but Its Lower Death Rate Needs Caution
Eli Lilly's Foundayo pill showed comparable heart safety to insulin in the ACHIEVE-4 trial, with fewer deaths but no proven benefit. The study met noninferiority for major heart events and showed better blood sugar and weight control. Foundayo is not yet FDA-approved for type 2 diabetes, and Lilly plans to seek approval.

Eli Lilly released new ACHIEVE-4 trial data showing its oral diabetes pill Foundayo met heart‑safety endpoints and showed lower death rates versus insulin.
likely upward pressure as investors price in potential future diabetes indication, tempered by uncertainty over mortality benefit.
The trial is the first public disclosure of these results; heart‑safety non‑inferiority is material for a large‑cap pharma and could drive near‑term buying on expectations of expanded label.
