The first and only targeted medicine for HR+/HER2- advanced breast cancer with a PIK3CA mutation available now for patients in Slovenia
- Alpelisib is the only treatment approved specifically to address PIK3CA mutation, underscoring Novartis commitment to reimagining cancer care.
- Every year around 3501people in Slovenia and 334,000 worldwide are diagnosed with advanced breast cancer, and approximately 40% of those with HR+/HER2- subtype have a PIK3CA mutation, which is associated with a poor prognosis2-11.
- We produce the drug substance for this important medicine in Novartis Technical operations in Mengeš.
Novartis today announced that alpelisib, which is used in combination with fulvestrant for the treatment of postmenopausal women, and men, with hormone receptor positive, human epidermal growth factor receptor-2 negative (HR+/HER2-) locally advanced or metastatic breast cancer with a PIK3CA mutation after disease progression following endocrine therapy as monotherapy is now available for patients in Slovenia. Alpelisib is the first and only treatment specifically approved for people with advanced breast cancer whose tumors harbor a PIK3CA mutation, which stimulates tumor growth and is associated with poor response to therapy12.
“Alpelisib is an important new therapy for HR+/HER2- advanced breast cancer patients whose tumors have a PIK3CA mutation, and we look forward to making it available for patients in Slovenia,” said Predrag Bogavac, Head Novartis Oncology in Slovenia. “Knowledge of PIK3CA status can better equip doctors as they develop a personalized upfront treatment plan for patients. Alpelisib offers new hope for advanced breast cancer patients with a PIK3CA mutation, who typically face a worse overall prognosis.”
What is a mutation? Mutations are like typos in our DNA. What are the types of mutation? We know sporadic mutations – they occur at random and are not passed down form parent to child. PIK3CA is a sporadic mutation. We also know inherited mutations – they are passed down from parent to child.BRCA1/2 is an inherited mutation.
Why is it important for patients to understand PIK3CA mutation? PIK3CA mutations have been linked to cancer growth. Just as tumor's HR and HER2 status, also the mutation status informs doctor whether certain proteins fuel growth of cancer. Tumor's mutation status may affect how the doctor manages patient's cancer care.
Patients with HR+/HER2- advanced breast cancer should be selected for treatment with alpelisib 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.
European Commission (EC) has approved alpelisib in July 2020. This approval has followed a positive opinion granted in May 2020 by the Committee for Medicinal Products for Human Use (CHMP) of the European Medicines Agency (EMA).
In Slovenia, we can be proud, as we produce the drug substance for this important medicine in Novartis Technical operations in Mengeš. Thus, Slovenian knowledge contributes to the modern treatment of patients with breast cancer.
