Piqray (alpelisib) is an oral medication that treats breast cancer with a specific set of receptors and mutations. It’s typically reserved for breast cancer that has spread or is considered advanced. It's also only approved for females who’ve already gone through menopause and for males. Piqray (alpelisib) treatment is convenient because it’s taken by mouth, only once daily. But it’s typically given in combination with fulvestrant (Faslodex), another anticancer medication that needs to be injected. Some common side effects of Piqray (alpelisib) include higher blood sugar levels and diarrhea.
Metastatic or advanced breast cancer that’s hormone receptor (HR)-positive, human epidermal growth factor receptor 2 (HER2)-negative, with PIK3CA mutations (in females who’ve gone through menopause and in males)
Piqray (alpelisib) is a kinase inhibitor. It targets proteins made by the PIK3CA gene. Typically, these proteins send signals to help cells grow and divide.
In people with certain types of breast cancer, there are changes to their PIK3CA gene (mutations). These mutations cause the proteins made by the PIK3CA gene to send too many signals. This leads to the cancer cells growing and dividing very fast.
Piqray (alpelisib) blocks the PIK3CA proteins from sending too many signals to cancer cells. With less signals to grow, the cancer cells won’t be able to grow as fast.

Depending on how serious your condition is, your provider might ask you to temporarily stop taking Piqray (alpelisib), lower your dose, or have you stop the medication permanently.
