Novartis AG Drug Afinitor Gets EU Nod for Breast Cancer
"The approval of Afinitor is an important milestone marking the first major advance for women in the European Union with hormone receptor-positive advanced breast cancer since the introduction of aromatase inhibitors more than 15 years ago," said Herve Hoppenot, President, Novartis Oncology. "Treatment with Afinitor gives women a new option in the battle against this advanced form of breast cancer, where there remains a significant unmet need."
The approval was based on the Phase III BOLERO-2 (Breast cancer trials of OraL EveROlimus-2) trial[1]. The randomized, double-blind, placebo-controlled, multi-center study of 724 patients found that treatment with Afinitor plus exemestane more than doubled median progression-free survival (PFS) to 7.8 months, compared to 3.2 months with exemestane alone (hazard ratio=0.45 [95% cl:0.38 to 0.54])(hazard ratio=0.45 [95% cl:p<0.0001), by local investigator assessment[3]. An additional analysis based on an independent central radiology review showed Afinitor extended median PFS to 11.0 months compared to 4.1 months (hazard ratio=0.38 [95% ci:0.31 to 0.48])(hazard ratio=0.38 [95% ci:p<0.0001)[3]. The most common grade 3-4 adverse reactions (incidence >= 2%) were stomatitis, infections, hyperglycemia, fatigue, dyspnea, pneumonitis and diarrhea[3].
"By boosting the effectiveness of endocrine therapy, Afinitor significantly extends the time women with hormone receptor-positive advanced breast cancer live without tumor progression," said Jose Baselga, MD, PhD, Chief, Hematology/Oncology, Massachusetts General Hospital and co-lead investigator of the BOLERO-2 trial. "Afinitor, the first mTOR inhibitor to be approved for this disease, has the potential to redefine the way this common form of advanced breast cancer is treated."
Each year, an estimated 220,000 women globally will be diagnosed with HR+ advanced breast cancer[1],[4]. For these women, endocrine therapy remains the cornerstone of treatment, but most will eventually develop resistance to therapy[5]. This therapeutic resistance has been associated with overactivation of the PI3K/AKT/mTOR pathway[5]. Afinitor works to target the mTOR pathway in cells. mTOR is a protein that acts as an important regulator of tumor cell division, blood vessel growth and cell metabolism[5].
The European Commission decision follows the positive opinion adopted by the Committee for Medicinal Products for Human Use on June 21, 2012 for Afinitor for the treatment of HR+ advanced breast cancer and applies to all 27 EU member states, plus Iceland and Norway[6]. On July 20, 2012, the US Food and Drug Administration approved Afinitor in combination with exemestane in the HR+/HER2- population after failure of letrozole or anastrazole[7]. Additional regulatory submissions for Afinitor in advanced breast cancer are under way worldwide. Afinitor is also being studied in HER2-positive breast cancer in two ongoing Phase III trials.
About Advanced Breast Cancer
Advanced breast cancer is comprised of metastatic breast cancer (stage IV) and locally advanced breast cancer (stage III)[8]. 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 bones or liver[8]. 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[8].
It is estimated that women with metastatic breast cancer have a life expectancy of approximately 18-36 months after diagnosis and median survival for women with stage III disease is less than five years[9],[10].
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[8]. The presence of estrogen receptor (ER) and/or progesterone receptor (PgR) is one of the most important predictive and prognostic markers in human breast cancers, and is collectively referred to as hormone receptor-positive[8].
About Afinitor (everolimus)
Afinitor® (everolimus) is approved in the European Union for the treatment of hormone receptor-positive (HR+), HER2/neu-negative (HER2-) 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+ breast cancer) in combination with exemestane after failure of treatment with letrozole or anastrozole.
Afinitor (everolimus) tablets is approved in more than 80 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 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.
Afinitor® Important Safety Information
Afinitor®/Votubia® can cause serious side effects including lung or breathing problems, infections and renal failure, which can lead to death. Mouth ulcers and mouth sores are common side effects. Afinitor/Votubia can affect blood cell counts, kidney and liver function, and blood sugar and cholesterol levels. Afinitor/Votubia may cause fetal harm in pregnant women. Highly effective contraception is recommended for women of child-bearing potential while receiving Afinitor/Votubia and for up to eight weeks after ending treatment. Women taking Afinitor/Votubia should not breast feed.
