Novartis drug Afinitor significantly extended time without disease progression in women with HER2 positive advanced breast cancer
• Everolimus plus trastuzumab and vinorelbine met primary endpoint of extending PFS compared to placebo plus trastuzumab and vinorelbine after prior therapy
• Results of Phase III trial, BOLERO-3, first to show potential benefit of everolimus in HER2 positive advanced breast cancer, an aggressive form of the disease
• Detailed data will be presented at the upcoming ASCO Annual Meeting and shared with regulatory authorities worldwide
Basel, May 17, 2013 - Results of a pivotal Phase III trial in women with HER2 positive (HER2+) advanced breast cancer showed that Afinitor® (everolimus) tablets in combination with trastuzumab (Herceptin®*) and vinorelbine significantly extended progression-free survival (PFS) after prior therapy when compared to treatment with placebo plus trastuzumab and vinorelbine,meeting the study's primary endpoint.
Efficacy and safety data from the BOLERO-3 (Breast cancer trials of OraL EveROlimus-3) trial were assessed as part of a prospectively planned analysis. These results will be presented on June 2 at the American Society of Clinical Oncology (ASCO) Annual Meeting in Chicago, Illinois, as well as at future medical congresses, and shared with regulatory authorities worldwide.
"We are encouraged by the BOLERO-3 results and are committed to helping improve treatment options for the HER2 positive patient population where there remains an unmet need," said Alessandro Riva, Global Head, Oncology Development & Medical Affairs, Novartis Oncology. "Everolimus works differently than any currently available treatment for HER2 positive breast cancer, and these results support its potential expanded role in advanced breast cancer."
Everolimus targets the PI3K/AKT/mTOR pathway, which is hyperactivated in many types of cancers. mTOR is a protein that acts as an important regulator of cell division, blood vessel growth and cell metabolism. Data confirm that blocking mTOR is a proven approach to maximize the benefit of existing advanced breast cancer treatments.
Everolimus is approved as Afinitor in more than 65 countries including the United States and the countries of the European Union to treat postmenopausal women with hormone receptor-positive, HER2 negative (HR+/HER2 negative) advanced breast cancer in combination with exemestane, after recurrence or progression following a non-steroidal aromatase inhibitor. The specific indications vary by country. HR+/HER2 negative advanced breast cancer is the most common form of the disease. Approximately 70% of all invasive breast cancers are positive for HR expression at the time of diagnosis.

BOLERO-3 is a Phase III, randomized, double-blind study of everolimus plus trastuzumab and vinorelbine conducted at 159 clinical trial sites globally. The trial included 569 women with HER2 positive locally advanced or metastatic breast cancer who were previously treated with a taxane and were resistant to trastuzumab. Participants were randomized 1:1 to receive either everolimus 5 mg/day orally or placebo, plus weekly vinorelbine 25 mg/m2 IV and weekly trastuzumab 2 mg/kg IV following loading dose of 4 mg/kg.
The primary endpoint of the trial is PFS. Secondary endpoints include overall survival, objective response rate, time to deterioration of performance status, changes in quality-of-life scores over time, clinical benefit rate, duration of response, time to response, safety and pharmacokinetics.
About advanced breast cancer
Advanced breast cancer comprises metastatic breast cancer (stage IV) and locally advanced breast cancer (stage III). Metastatic breast cancer is the most serious form of the disease and occurs when the cancer has spread to other parts of the body, such as the brain, bones or liver. Locally advanced breast cancer occurs when the cancer has spread to lymph nodes and/or other tissue in the area of the breast, but not to distant sites in the body.
Overactivation of the PI3K/AKT/mTOR pathway has been associated with disease progression in women with advanced breast cancer. Eighty percent of advanced breast cancer is either hormone receptor-positive (HR+) and/or human epidermal growth factor receptor-2 positive (HER2 positive),.
HR+ advanced breast cancer is the most common type of advanced breast cancer, with an estimated 220,000 women diagnosed globally each year. HR+ advanced breast cancer is characterized by hormone receptor-positive tumors, a group of cancers that express receptors for certain hormones such as estrogen and progesterone. Cancer cell growth can be driven by these hormones.
In HER2 positive advanced breast cancer, overexpression of the HER2 gene activates signaling pathways, such as the mTOR pathway, leading to the uncontrolled growth and division of cancer cells,. Globally, an estimated 140,000 women are living with HER2 positive advanced breast cancer.
About Afinitor® (everolimus)
Everolimus is approved as Afinitor® in the European Union for the treatment of hormone receptor-positive, HER2 negative (HR+/HER2 negative) advanced breast cancer, in combination with exemestane, in postmenopausal women without symptomatic visceral disease after recurrence or progression following a non-steroidal aromatase inhibitor. In the United States, Afinitor is approved for the treatment of postmenopausal women with advanced hormone receptor-positive, HER2 negative breast cancer (advanced HR+/HER2 negative breast cancer) in combination with exemestane after failure of treatment with letrozole or anastrozole.
Afinitor (everolimus) tablets is approved in more than 95 countries, including the United States and throughout the European Union, in the oncology settings of advanced renal cell carcinoma following progression on or after vascular endothelial growth factor (VEGF)-targeted therapy, and in the United States and European Union for locally advanced, metastatic or unresectable progressive neuroendocrine tumors of pancreatic origin.
Everolimus is also available from Novartis for use in certain non-oncology patient populations under the brand names Afinitor® or Votubia®, Certican® and Zortress® and is exclusively licensed to Abbott and sublicensed to Boston Scientific for use in drug-eluting stents.
Indications vary by country and not all indications are available in every country. The safety and efficacy profile of everolimus has not yet been established outside the approved indications. Because of the uncertainty of clinical trials, there is no guarantee that everolimus will become commercially available for additional indications anywhere else in the world.
