Compliance of French academic clinical trials with the Clinical Trial Facilitation and Coordination Group recommendations on contraception and pregnancy testing requirements.

Abstract

The Clinical Trials Coordination and Facilitation Group has issued recommendations on contraception and pregnancy testing to help sponsors meet regulatory expectations and harmonize practices to limit embryofetal risks in clinical trials. Our objective was to assess the compliance of French academic clinical trials with these recommendations and to describe the mitigation measures required by sponsors in their trials. A cross-sectional study was performed on the French academic drug trials authorized by the national competent authority between January 2015 and June 2018. We included trials which tested systemic administration of drugs and enrolled men or women of childbearing potential. Data from 97 trials included were compiled. One-third of the trials (23.8%-43.3%, 95% confidence interval) complied with the Clinical Trial Facilitation and Coordination Group recommendations. No improvement over time or according to embryofetotoxic status or drug duration exposure was found. Contraception was required in 56.7% of trials and was more often required in case of potentially embryofetotoxic drugs (68.5% vs 41.9%, p = 0.013) or exposure over 1 month (71.7% vs 43.8%, p = 0.006). Pregnancy testing at inclusion was required in 59.1% of trials and additional testing in 17.2%. Pregnancy testing at inclusion was more often required in trials with drug exposure above 1 month (67.4% vs 45.8%, p = 0.035). French academic sponsors barely met the recommendations on contraception and pregnancy testing potentially leading to potential embryofetal risks in case of pregnancy. They need to implement these recommendations quickly.
