FDA grants Roche's Avastin Priority Review for recurrent platinum-resistant ovarian cancer
Roche (SIX: RO, ROG; OTCQX: RHHBY) today announced that the U.S. Food and Drug Administration (FDA) has accepted the company's supplemental Biologics License Application (sBLA) and granted Priority Review for Avastin (bevacizumab) plus chemotherapy for the treatment of women with recurrent platinum-resistant ovarian cancer.
“The majority of women with ovarian cancer will become resistant to platinum therapy and a quarter of women will have platinum-resistant disease at the time of a first recurrence. New treatment options are needed,” said Sandra Horning, M.D., chief medical officer and head of Global Product Development. “We look forward to working with the FDA to bring this potential option to women with this difficult-to-treat cancer as soon as possible.”
The designation of Priority Review status is granted to medicines that the FDA believes have the potential to provide “significant improvements in the safety or effectiveness of the treatment, diagnosis, or prevention of serious conditions when compared to standard applications.”1 The sBLA for Avastin plus chemotherapy for recurrent platinum-resistant ovarian cancer is based on data from the Phase III AURELIA trial with an FDA action date of November 19, 2014.
About the AURELIA Study2
AURELIA is a company-sponsored, multicentre, randomised, open-label, Phase III study in 361 women with platinum-resistant recurrent epithelial ovarian, primary peritoneal or fallopian tube cancer who had received no more than two anticancer regimens prior to enrolment in the trial. Participants were randomised to one of six treatment arms (paclitaxel, topotecan or liposomal doxorubicin with or without Avastin). Study data showed:
- The study met its primary endpoint and showed that Avastin plus chemotherapy reduced the risk of disease worsening (progression-free survival, PFS) by 52 percent compared to chemotherapy alone (median PFS: 6.7 months vs. 3.4 months; Hazard Ratio (HR)=0.48, p<0.001). No statistically significant difference was seen in the secondary endpoint of overall survival (median OS: 16.6 months vs. 13.3 months; HR=0.85, p<0.174).2
- Women in the Avastin plus paclitaxel arm (n=60) experienced a 54 percent reduction in the risk of their disease worsening (median PFS: 10.4 months vs. 3.9 months; HR=0.46, 95% CI 0.30-0.71)3 and a 35 percent reduction in the risk of death (median OS: 22.4 months vs. 13.2 months; HR=0.65, 95% CI 0.42-1.02).4
- The study showed women who received Avastin plus chemotherapy had a significantly higher rate of tumour shrinkage (objective response rate, ORR) compared to chemotherapy alone when evaluated by the RECIST criteria (27.3 percent vs. 11.8 percent, respectively; p=0.001).2
- Grade 3-5 adverse events occurring at a higher incidence (> 2 percent) in women receiving Avastin plus chemotherapy compared to women receiving chemotherapy alone were hypertension (high blood pressure; 7 percent vs. 1 percent), proteinuria (too much protein in the urine; 2 percent vs. 0 percent) and gastrointestinal perforations (a hole in the stomach or intestine; 2 percent vs. 0 percent).2
About Ovarian Cancer
Ovarian cancer causes more deaths than any other gynaecological cancer.5 In 2014, nearly 22,000 women will be diagnosed with ovarian cancer in the United States and more than 14,000 will die from the disease.6 Patients are said to have ‘platinum-resistant’ disease if the disease worsens within six months of completing platinum-based chemotherapy. One quarter of those who relapse after initial treatment - more than 4,300 women - will have platinum-resistant cancer, the most difficult-to-treat form of the disease.2,6
Worldwide, ovarian cancer is the seventh most commonly diagnosed cancer in women, with an estimated 230,000 cases diagnosed around the world every year and there are approximately 150,000 deaths from the disease making it the deadliest of all gynaecological cancers.5
About Avastin – 10 years of transforming cancer care
With the initial approval in the USA 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 U.S. for the treatment of colorectal cancer, non-small cell lung cancer and kidney cancer. In addition, Avastin is approved in the U.S. 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 1.4 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.
About Avastin – mechanism of action
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.
