Register Terminal Cancer Patients in Cancer Trials, FDA Says

Share

FDA has published a draft guidance, Cancer Clinical Trial Eligibility Criteria: Approach to Available Therapy in Non-Curative Settings, with recommendations for including patients who have not received available therapy for their cancer in clinical trials of investigational drugs and biological products in a non-curative setting. The document says eligibility criteria for such clinical trials should generally require that patients have received available therapies that offer the potential for cure in a substantial proportion of patients in clinical trials evaluating investigational cancer drugs.

Alternatively, FDA says, such available therapy should be administered to all patients in the trial, where the investigational drug is added to such therapy. “However, eligibility criteria in which patients receive an investigational drug(s) in lieu of available therapy are reasonable in the non-curative setting when patients have been provided with adequate information to make an informed decision on trial participation,” the guidance adds.

The draft also describes the information that should be included in the informed consent when the approach is taken and includes recommendations on efficacy analyses under this approach.

Commenting on the draft, FDA Oncology Center of Excellence director Richard Pazdur says the agency believes patients with incurable cancers, if provided adequate information to make an informed decision, should be eligible to participate in oncology clinical trials. “If there is no scientific rationale for excluding these patients,” he says, “then clinical trial eligibility criteria should be broadened to include these patients, with appropriate informed consent.”
