OncoMatch/Clinical Trials/NCT07405801
A Phase II Study Evaluating the Efficacy and Safety of Inavolisib Plus Ribociclib Plus Fulvestrant Versus Placebo Plus Ribociclib Plus Fulvestrant in Participants With Advanced Breast Cancer
Is NCT07405801 recruiting? Yes, currently enrolling (May 2026). This Phase 2 trial studies multiple treatments including Inavolisib and Ribociclib for breast cancer.
Treatment: Inavolisib · Ribociclib · Fulvestrant — A study to evaluate the efficacy and safety of triplet combination of inavolisib plus ribociclib and fulvestrant versus placebo plus ribociclib and fulvestrant in the first-line setting in participants with endocrine-therapy-resistant hormone receptor (HR)-positive (HR+), human epidermal growth factor receptor 2-negative (HER2-) advanced breast cancer (ABC) with chromosome 8p loss (chr8p loss) and without PIK3CA mutation.
