The first combination of targeted therapies for any cancer to receive a positive opinion
BASEL, Switzerland | Mar 26, 2007 | Roche today announced that the European Union’s Committee for Human Medicinal Products (CHMP) has issued a positive recommendation for the use of Herceptin in combination with an aromatase inhibitor for the treatment of postmenopausal patients with HER2- and hormone receptor-positive metastatic breast cancer. The recommendation is based on data from the international phase III TAnDEM study which showed that the addition of Herceptin to hormonal therapy doubles the median progression-free survival (time patients live without their cancer progressing), from 2.4 months to 4.8 months.1
Comprehensive reviews have suggested that approximately two thirds of breast tumours are hormone receptor positive2. Of these, a significant percentage (up to 25%) are also HER2-positive3,4,5
TAnDEM is the first randomised study to show that this specific subset of ‘co-positive’ patients (both HER2- and hormone receptor-positive) is ‘high-risk’, making the positive results with Herceptin even more meaningful.
"The results from the TAnDEM study show once again that Herceptin should be the backbone for all patients with HER2-positive breast cancer – it consistently benefits patients regardless of whether it is given in the early- or advanced-stage settings, or whether it is in combination with chemotherapy, hormonal therapy, or as a single agent," said Eduard Holdener, Chief Medical Officer of Roche. "This combination offers a new treatment regimen for patients who suffer from a particularly aggressive form of breast cancer, and we are pleased to have been able to progress this application so quickly."
The positive opinion proposes the approval of Herceptin in this combination by the European Commission. Herceptin is currently approved for the treatment of early and metastatic (advanced) HER2-positive disease, and has demonstrated a survival benefit in both settings. The new approval will also allow Herceptin to be used in combination with hormonal therapy for advanced breast cancer.
About the TAnDEM study
TAnDEM, conducted by Roche, is a randomised, phase III trial, which evaluated Herceptin in combination with the hormonal therapy anastrozole versus anastrozole alone as first-line therapy (or second-line hormonal therapy) in postmenopausal women with advanced (metastatic) HER2-positive and hormone receptor-positive (ER-positive and/or PR-positive) breast cancer. Enrolment to the trial began in 2001, and 208 HER2 and hormone receptor co-positive patients were randomised at 77 centres in 22 countries across the world.
Median progression-free survival, the primary endpoint of the trial, was 4.8 months for patients who received the combination compared to 2.4 months for patients who received hormonal therapy alone (p = 0.0016). Patients in the combination arm also responded significantly better to treatment (overall response rate was 20.3% versus 6.8%; p = 0.018). There was also a positive trend in median overall survival (28.5 months versus 23.9 months; p = 0.325); this is despite the fact that in the hormonal therapy alone arm, more than half of patients (58/104) crossed over to receive Herceptin during the trial when their disease had progressed, and an additional 15 (out of 104) patients received Herceptin at a later time point.
Overall safety data in both arms of the trial were acceptable given the known safety profile of each of the drugs in the advanced breast cancer setting. Patients in this study will continue to be followed for any side-effects.
About breast cancer and Herceptin
Eight to nine percent of women will develop breast cancer during their lifetime, making it one of the most common types of cancer in women6. Each year more than one million new cases of breast cancer are diagnosed worldwide, with a death rate of nearly 400,000 people per year.
In HER2-positive breast cancer, increased quantities of the HER2 protein are present on the surface of the tumour cells. This is known as ‘HER2 positivity.’ High levels of HER2 are present in a particularly aggressive form of the disease which responds poorly to chemotherapy. Research shows that HER2-positivity affects approximately 20-30% of women with breast cancer.
Herceptin is a humanised antibody, designed to target and block the function of HER2, a protein produced by a specific gene with cancer-causing potential. In addition to its efficacy in the early-stage breast cancer setting, Herceptin also has demonstrated improved survival in the advanced (metastatic) setting, where its addition to chemotherapy allows patients to live up to one-third longer than chemotherapy alone.7
Herceptin received approval for use in the European Union for advanced (metastatic) HER2-positive breast cancer in 2000 and for early HER2-positive breast cancer in 2006. In the advanced setting, Herceptin is approved for use as a first-line therapy in combination with paclitaxel where anthracyclines are unsuitable, as first-line therapy in combination with docetaxel, and as a single agent in third-line therapy. In the early setting, Herceptin is approved for use following standard (adjuvant) chemotherapy. Herceptin is marketed in the United States by Genentech, in Japan by Chugai and internationally by Roche.
To date, over 350,000 patients with HER2-positive breast cancer have been treated with Herceptin worldwide.
