Breast cancer drug combo safety study ends early – only 4 patients enrolled
NCT ID NCT04967248
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This was an observational study that planned to track side effects, especially high blood sugar, in patients taking alpelisib (Piqray) plus fulvestrant for a type of advanced breast cancer. It included postmenopausal women and men whose cancer had a specific gene mutation (PIK3CA) and had worsened after hormone therapy alone. However, the study was terminated early after enrolling only 4 participants, so it provides very limited information.
