Novartis Piqray data show survival benefit for patients with HR+/HER2- advanced breast cancer with a PIK3CA mutation
In SOLAR-1 final analysis, Piqray (alpelisib) plus fulvestrant demonstrated 8 months clinically relevant improvement in overall survival (OS) in HR+/HER2- advanced breast cancer (aBC)
patients with a PIK3CA mutation compared to fulvestrant alone1
14+ months OS improvement was achieved in patients with lung or liver metastases, which are observed in 41% of postmenopausal women with HR+ aBC, and considered more aggressive and
challenging to treat1-3
- Data add to growing body of evidence for Piqray, the first and only treatment specifically approved for aBC with a PIK3CA mutation
Basel, September 19, 2020 — Novartis today announced results of the final overall survival (OS) analysis from the SOLAR-1 trial, which evaluated Piqray (alpelisib) in combination with fulvestrant, compared to fulvestrant alone, in hormone receptor positive, human epidermal growth factor receptor-2 negative (HR+/HER2-) advanced breast cancer patients with tumors harboring a PIK3CA mutation. Piqray is the only treatment approved in Europe, the United States and 15 other countries specifically for people with HR+/HER2- advanced breast cancer with a PIK3CA mutation. These data will be presented as a late-breaking oral presentation during the ESMO Virtual Congress 2020.
In the study, there was a clinically relevant improvement in OS of eight months for patients with a PIK3CA mutation taking Piqray plus fulvestrant compared to fulvestrant alone (median OS 39.3 months vs. 31.4 months; one-sided p≤0.0161; HR=0.86; 95% CI: 0.64-1.15; p=0.15)1. This difference did not reach the prespecified threshold of statistical significance set for the secondary objective of OS in patients with PIK3CA-mutated breast cancer. A more than 14 month OS improvement was observed in patients with lung or liver metastases, which signify more aggressive disease (median OS 37.2 months vs. 22.8 months; HR=0.68; 95% CI: 0.46-1.00)1-3.
“These results build on previous data showing that alpelisib nearly doubled median progression-free survival in this patient population,” said Fabrice André, MD, PhD, research director and head of INSERM Unit U981, professor in the Department of Medical Oncology at Institut Gustave Roussy in Villejuif, France, and global SOLAR-1 principal investigator. “Patients whose tumors have a PIK3CA mutation, particularly those with lung or liver metastases, have a more aggressive, harder to treat cancer, so these results showing alpelisib offers longer life, are promising.”
