Dr. Gary Lyman, a Duke University researcher who was on the FDA advisory panel that recommended revoking Avastin's approval for breast cancer, wrote in an email that he agreed with the company's decision not to seek approval for ovarian cancer.
"The situation is very similar" to the results in breast cancer, and approval is unlikely unless a biological marker or test can show which patients might benefit, he wrote.
About 220,000 new cases of ovarian cancer are diagnosed each year around the world, and it causes 140,000 deaths. In the United States, the National Cancer Institute estimates 22,000 new cases and 15,000 deaths each year.
