A Study Evaluating the Safety of Inavolisib and Fulvestrant With or Without Palbociclib in Participants With Advanced Breast Cancer (ABC) and Type 2 Diabetes

15. september 2026 oppdatert av: Hoffmann-La Roche

A Phase II Prospective, Open-Label Safety Study of Inavolisib and Fulvestrant With or Without Palbociclib in Participants With PIK3CA-Mutated Hormone Receptor-Positive, HER2-Negative Advanced Breast Cancer and Type 2 Diabetes

This study will evaluate the safety of inavolisib in combination with fulvestrant, with or without palbociclib, in participants with PIK3CA-mutated, HR+, HER2-negative ABC and type 2 diabetes.
