Piqray received a positive opinion from the Committee for Medicinal Products for Human Use of the European Medicines Agency.
CHMP recommended approval of Piqray (alpelisib) in combination with fulvestrant for the treatment of postmenopausal women, and men, with hormone receptor positive, human epidermal growth factor receptor-2 negative locally advanced or metastatic breast cancer with a PIK3CA mutation after disease progression following endocrine therapy as monotherapy.
Piqray is sponsored by Novartis.
The CHMP opinion is based on results of the Phase III SOLAR-1 trial that showed Piqray plus fulvestrant nearly doubled median progression-free survival compared to fulvestrant alone in HR+/HER2- advanced breast cancer patients with tumors harboring a PIK3CA mutation (median PFS 11.0 months vs. 5.7 months; HR=0.65, 95% CI: 0.50-0.85; p<0.001), the study’s primary endpoint. PFS subgroup analyses demonstrated consistent efficacy in favor of Piqray, irrespective of presence or absence of lung/liver metastases.
In SOLAR-1, most adverse events were mild to moderate in severity and generally manageable through dose modifications and medical management.
The European Commission will review the CHMP recommendation and usually delivers a final decision within approximately two months. The decision will be applicable to all 27 European Union member states plus the United Kingdom, Iceland, Norway and Liechtenstein. Additional regulatory filings are underway with other health authorities worldwide.
Patients with HR+/HER2- advanced breast cancer should be selected for treatment with Piqray based on the presence of a PIK3CA mutation in tumor or plasma specimens, using a validated test. If a mutation is not detected in a plasma specimen, tumor tissue should be tested if available.
