Itovebi (inavolisib) in combination with Ibrance (palbociclib) and Faslodex (fulvestrant) is FDA-approved for use in patients with endocrine-resistant, hormone receptor (HR)-positive, ERBB2 (HER2)-negative, locally advanced or metastatic breast cancer harboring PIK3CA mutations (FDA.gov). |
| Letrozole | Femara | Letrozol | Aromatase Inhibitor 3 | Femara (letrozole) is an aromatase inhibitor, which inhibits estrogen synthesis, and is approved for postmenopausal women with hormone receptor positive breast cancer (FDA.gov). |
