Cancer Trial Eligibility Criteria Guidance

Share

FDA has published a draft guidance, Cancer Clinical Trial Eligibility Criteria: Washout Period and Concomitant Medicines, part of a series of guidances with recommendations about eligibility criteria for clinical trials of investigational drugs or biologics regulated by CDER or CBER to treat cancer. This document specifically has recommendations about the appropriate use of washout periods and concomitant medication exclusions.

The guidance says that eligibility criteria sometimes are more restrictive than necessary and expanding the criteria to be more inclusive is one trial consideration that may improve the diversity of clinical trial populations.

“Because there is variability in investigational drugs and trial objectives, eligibility criteria should be developed taking into consideration the mechanism of action of the drug, the targeted disease or patient population, the anticipated safety of the investigational drug, the availability of adequate safety data, and the ability to recruit trial participants from the patient population to meet the objectives of the clinical trial,” FDA says.
