Everolimus is the first new licensed therapeutic approach in fifteen years offering an impact on hormone responsive advanced breast cancer which affects over 30,000 women in the UK. Despite NICE describing everolimus as “a step change in treatment”, its final appraisal determination (FAD) recommends patients should not have access to the therapy via the NHS, marking the sixth treatment that NICE has turned down for patients with advanced breast cancer since 2011.
Everolimus is approved for use in postmenopausal women with oestrogen receptor-positive (ER+), human epidermal growth factor receptor 2 negative (HER2-) advanced breast cancer, in combination with exemestane, that has recurred or progressed following treatment with a non-steroidal aromatase inhibitor. The most common form of advanced breast cancer is the oestrogen receptor-positive type which accounts for approximately 75% of all breast cancers.
Professor Stephen Johnston, Professor of Breast Cancer Medicine at The Royal Marsden NHS Foundation Trust, said, “Everolimus represents a significant advance in the treatment of hormone receptor positive advanced breast cancer and it is disappointing that NICE will not be recommending its routine use on the NHS. For the first time we have a new treatment option which is proven to enhance sensitivity to hormone therapy, ultimately delaying the need for chemotherapy in this setting which is an important benefit for many patients. It is frustrating that because of this decision, a drug with this magnitude of clinical benefit will now not be available to all patients who could benefit.”
A comprehensive range of clinical and cost effectiveness evidence, including data from the pivotal Phase III BOLERO-2 (Breast cancer trials of OraL EverROlimus-2) study involving more than 700 patients, was submitted to the NICE Appraisal Committee and found that:
• Treatment with everolimus plus exemestane more than doubled median progression-free survival (PFS) to 11.0 months compared to 4.1 months based on an independent central radiology review
• Improvements in PFS with everolimus in combination with exemestane were achieved without compromising health-related quality of life.
