The European Union’s Committee for Medicinal Products for Human Use (CHMP) has issued a positive opinion on the use of Roche's Avastin (bevacizumab) in combination with standard chemotherapy (paclitaxel and cisplatin or, alternatively, paclitaxel and topotecan in patients who cannot receive platinum therapy) for the treatment of adult patients with persistent, recurrent or metastatic carcinoma of the cervix. Cervical cancer is most commonly diagnosed in younger women, those between the ages of 35 and 44, and every year over 30,000 women in the EU are diagnosed with the disease.
“Treatment options in Europe for women whose cervical cancer has recurred, persisted or spread are currently limited to chemotherapy,” said Sandra Horning, M.D., chief medical officer and head of global product development. “This CHMP positive opinion for Avastin brings us one step closer to providing women with a much needed, new treatment option that can help them live longer compared to chemotherapy alone.”
The EU filing was based on the significant survival benefit in the pivotal GOG-0240 study, which showed that women who received Avastin plus chemotherapy had a statistically significant 26 percent reduction in the risk of death, representing a median improvement in survival of nearly four months, compared to women who received chemotherapy alone (median overall survival: 16.8 months vs. 12.9 months; Hazard Ratio (HR)=0.74, p=0.0132).
In August 2014 in the US, and in December 2014 in Switzerland, Avastin was approved in combination with paclitaxel and cisplatin or paclitaxel and topotecan chemotherapy for the treatment of women with persistent, recurrent or metastatic carcinoma of the cervix, based on the results of the GOG-0240 study.
GOG-0240 is an independent, National Cancer Institute (NCI)-sponsored study of the Gynecologic Oncology Group (GOG) that assessed the efficacy and safety profile of Avastin plus chemotherapy (paclitaxel and cisplatin or paclitaxel and topotecan) in women with persistent, recurrent or metastatic cervical cancer.
Study data from 452 women showed: The study met its primary endpoint of improving overall survival (OS) with a statistically significant 26 per cent reduction in the risk of death, representing a median gain in survival of 3.9 months, compared with those who received chemotherapy alone (median overall survival: 16.8 months vs. 12.9 months; (HR)=0.74, p=0.0132); The study showed that women who received Avastin plus chemotherapy had a significantly higher rate of tumour shrinkage (objective response rate, ORR) compared with those who received chemotherapy alone (45 per cent [95% CI: 0.39%-0.52%] vs. 34 per cent [95% CI 0.28%-0.40%]); Overall, the safety profile in the study was consistent with that seen in previous pivotal studies of Avastin across tumour types, except for an increase in gastrointestinal-vaginal fistulas observed in patients who received Avastin plus chemotherapy compared to those who received chemotherapy alone (8.3% vs. 0.9% respectively). All patients with gastrointestinal-vaginal fistulas after treatment with Avastin plus chemotherapy had a history of prior pelvic radiation.
With the initial approval in the United States for advanced colorectal cancer in 2004, Avastin became the first anti-angiogenic therapy made widely available for the treatment of patients with an advanced cancer.
Today, Avastin is continuing to transform cancer care through its proven survival benefit (overall survival and/or progression free survival) across several types of cancer. Avastin is approved in Europe for the treatment of advanced stages of breast cancer, colorectal cancer, non-small cell lung cancer, kidney cancer and ovarian cancer, and is available in the United States for the treatment of colorectal cancer, non-small cell lung cancer, kidney cancer, cervical cancer and platinum-resistant, recurrent ovarian cancer. In addition, Avastin is approved in the United States and over 60 other countries worldwide for the treatment of patients with progressive glioblastoma following prior therapy. Avastin is approved in Japan for the treatment of the advanced stages of colorectal, non-small cell lung cancer, breast cancer, ovarian cancer and malignant glioma, including newly diagnosed glioblastoma.
Avastin has made anti-angiogenic therapy a fundamental pillar of cancer treatment today. Over 1.5 million patients have been treated with Avastin so far. A comprehensive clinical programme with more than 500 ongoing clinical trials is investigating the use of Avastin in over 50 tumour types.
An independent blood supply is critical for a tumour to grow beyond a certain size (2mm) and spread (metastasise) to other parts of the body. Tumours develop their own blood supply in a process called angiogenesis by releasing vascular endothelial growth factor (VEGF) – a key driver for tumour growth. Avastin is an antibody that precisely targets and inhibits VEGF. Precise VEGF inhibition by Avastin allows it to be combined effectively with a broad range of chemotherapies and other anti-cancer treatments with limited additional impact on the side effects of these therapies.
