Lilly has recently initiated the Ph3 tirzepatide HFpEF trial, called SUMMIT (view CT.gov record). Recall, during Lilly’s 2021 guidance call (December 15, 2020), Lilly first disclosed plans to develop tirzepatide for the treatment of HFpEF (previous FENIX insight). Below, FENIX provides an overview of SUMMIT, including a comparative analysis with Novo’s semaglutide HFpEF trial (STEP HFpEF).
