Femara(r) Gains U.S. FDA Approval as Only Post-Tamoxifen Treatment for Early Breast Cancer

Basel, Switzerland (ots/PRNewswire) - - New Treatment Option the First to Help Postmenopausal Women With Early Breast Cancer Remain Cancer-Free Following Adjuvant Tamoxifen Therapy Femara(R) (letrozole) is the first therapy approved by the U.S. Food and Drug Administration (FDA) for the extended adjuvant treatment of postmenopausal women with early breast cancer who have received adjuvant (post-surgery) tamoxifen therapy for five years, Novartis announced today. "Femara truly provides hope to women who have survived early breast cancer by offering them an improved chance of remaining cancer-free," said Diane Young, M.D., vice president and global head of Clinical Development at Novartis Oncology. "This priority review approval marks the first time that nearly 100,000 women who complete tamoxifen therapy each year will have a medical option to reduce their ongoing risk of breast cancer recurrence." The term extended adjuvant describes the period following adjuvant (post- surgery) treatment with tamoxifen. Even years after breast cancer diagnosis and primary treatment, the ongoing risk of breast cancer recurrence remains significant for all patients. Globally, approximately one-third of women with estrogen receptor-positive early breast cancer experience a recurrence, and over half of those recurrences occur more than five years after surgery. While tamoxifen is beneficial for five years post surgery, if used beyond that period, the risks associated with it outweigh the benefits. Extended adjuvant treatment with Femara is the first therapy to effectively reduce ongoing risk of breast cancer recurrence. The approval for the extended adjuvant indication was based on results from the landmark, international, independent MA-17 study, which included more than 5,100 postmenopausal women and was coordinated by the National Cancer Institute of Canada Clinical Trials Group at Queens University in Kingston, Ontario, Canada, and supported by Novartis. Initial results were published in the New England Journal of Medicine in October 2003. The study showed that Femara reduced the risk of cancer coming back, or disease-free survival, by 38% and significantly increased a woman's chance of staying cancer-free. This is particularly important because when breast cancer recurs, it has very often spread beyond the breast (metastatic disease), which can have serious consequences. Femara also greatly reduced the chance of breast cancer returning to another part of the body, or distant metastases, by 39%. About Femara Femara is a leading once-a-day oral aromatase inhibitor that is also indicated for first-line treatment of postmenopausal women with hormone receptor-positive or hormone receptor-unknown locally advanced or metastatic breast cancer and for the treatment of advanced breast cancer in postmenopausal women with disease progression following antiestrogen therapy, and as neo-adjuvant (pre-operative) therapy. Not all indications are available in every country. Novartis has filed in the European Union for the indication of extended adjuvant treatment of early breast cancer in postmenopausal women who have completed adjuvant (post-surgery) tamoxifen therapy. In addition to the U.S., this indication is now approved in the United Kingdom, Switzerland, Mexico, Korea and other countries around the world. Femara is currently available in more than 80 countries worldwide.
