A Study of Tersolisib (LY4064809) and Abemaciclib With Hormone Therapies in Participants With PIK3CA-Mutated Early Breast Cancer (PIKALO-3)
A Phase 2, Open-label, Randomized Study Investigating the Tolerability of Concurrent Versus Staggered Administration of Abemaciclib and Endocrine Therapy With Tersolisib in Patients With HR+, HER2- Node-Positive, PIK3CA-Mutated Early Breast Cancer.
The main purpose of this study is to compare two ways of giving the anti-cancer medicines abemaciclib and hormone therapy with tersolisib in participants with early breast cancer that has a genetic mutation (PIK3CA mutation).
For each participant, the study will last up to 56 weeks and include 12 visits.
