This trial is for adults with ER-positive, HER2-negative advanced breast cancer carrying a qualifying PIK3CA mutation, after progression on CDK4/6-inhibitor plus endocrine therapy. At most one advanced-disease treatment line is allowed; prior chemotherapy for advanced disease is excluded.

The idea: compare two doses of oral inavolisib, each combined with fulvestrant injections into muscle. Inavolisib blocks PI3K growth signaling; fulvestrant blocks estrogen receptors. Both randomized groups receive active treatment. Researchers compare tumor responses and side effects. Endocrine treatment must remain appropriate.

This phase 2 study plans 80 patients. Roche sponsors four recruiting US sites.
