More Males Needed in Breast Cancer Trials: FDA
FDA wants to start seeing more males included in breast cancer drug trials and using real world data can help. A draft guidance, Male Breast Cancer: Developing Drugs for Treatment, has been released that provides recommendations on how additional data to support efficacy and safety for male patients with breast cancer can be generated through a variety of trial designs using different data sources, including studies using real-world data, according to FDA Oncology Center of Excellence director Richard Pazdur.
“Less than one percent of all breast cancer cases occur in men, but men are more likely to be diagnosed at an older age and have a more advanced stage of disease,” Pazdur is quoted as saying in an agency release. “As breast cancer in men is rare, they have typically not been included in clinical trials for breast cancer treatment. This has led to a lack of data, so their treatment is generally based upon studies and data collected in women. While some FDA-approved treatments are gender-neutral in their indication, many therapies are only approved for women and further data may be necessary to support labeling indications for men.”
The guidance encourages sponsors to discuss their breast cancer drug development plan early in development with CDER or CBER. It say scientific rationale should be included in a protocol when proposing to exclude males from breast cancer trials. “FDA does not intend to consider low expected accrual rates of male patients with breast cancer to be a sufficient scientific rationale for excluding them from a clinical trial,” it says.
