In May, the U.S. Food and Drug Administration (FDA) approved Piqray® (alpelisib) for treating advanced breast cancer. It is approved for use in combination with Faslodex® (fulvestrant) to treat postmenopausal women and men with HR-positive, HER2-negative, PIK3CA-mutated, advanced breast cancer who have already been treated with at least one hormone therapy. The FDA also approved a tumor test to look for the PIK3CA mutation.
Piqray® (alpelisib) is a PI3K (Phosphoinositide 3-kinase) inhibitor. The PI3K enzymes are part of the PI3K/AKT/mTOR pathway, which helps control how cells communicate as well as cell growth.
PIK3CA is the gene that is involved in making PI3K enzymes. A mutation in the PIK3CA gene leads to abnormal PI3K function, which can be targeted by Piqray®. Approximately 40% of patients living with HR+/HER2- breast cancer have this PIK3A mutation.
