Alpelisib, sold under the brand name Piqray, is a chemotherapy medication used to treat certain types of breast cancer. It is used together with fulvestrant. It results in about an extra 5 months of life without the disease getting worse. It is taken by mouth.
Common side effects include high blood sugar, kidney problems, diarrhea, rash, low blood cells, liver problems, pancreatitis, vomiting, and hair loss. Other side effects may include anaphylaxis, infertility, and pneumonitis. Use during pregnancy may harm the baby. It is an alpha-specific PI3K inhibitor.
Alpelisib is used in combination with fulvestrant for the treatment of postmenopausal women, and men, with hormone receptor (HR)‑positive, human epidermal growth factor receptor 2 (HER2)‑negative, locally advanced or metastatic breast cancer with a PIK3CA mutation after disease progression following endocrine therapy as monotherapy.
The dose is 300 mg twice per day, until no longer effective or side effects become to great.
In May 2019, alpelisib was approved in the United States for use in combination with the endocrine therapy fulvestrant, to treat postmenopausal women, and men, with hormone receptor (HR)-positive, human epidermal growth factor receptor 2 (HER2)-negative, PIK3CA-mutated, advanced or metastatic breast cancer following progression on or after an endocrine-based regimen.
The efficacy of alpelisib was studied in the SOLAR-1 trial (NCT02437318), a randomized trial of 572 postmenopausal women and men with HR-positive, HER2-negative, advanced or metastatic breast cancer whose cancer had progressed while on or after receiving an aromatase inhibitor.
The FDA granted the application for alpelisib priority review designation and granted approval of Piqray to Novartis. The FDA granted approval of the therascreen PIK3CA RGQ PCR Kit to Qiagen Manchester, Ltd.
On 28 May 2020, the Committee for Medicinal Products for Human Use (CHMP) of the European Medicines Agency (EMA) adopted a positive opinion, recommending the granting of a marketing authorization for the medicinal product alpelisib (Piqray), intended for the treatment of locally advanced or metastatic breast cancer with a PIK3CA mutation. The applicant for this medicinal product is Novartis Europharm Limited. Alpelisib was approved for medical use in the European Union in July 2020.
