Single-arm clinical trials that supported FDA accelerated approvals have modest effect sizes and were at high risk of bias

OBJECTIVE: To describe effect sizes of single-arm clinical trials that supported AA approvals.

STUDY DESIGN AND SETTING: We reviewed all the single-arm approvals granted by the FDA-AA pathway between June1992 to December2020. Two independent reviewers identified single-arm studies and extracted data from FDA Full-Medical Reviews. We performed a meta-analysis to estimate the effect sizes and compared it between studies that met post-approval FDA requirements for RCTs with those that did not.

RESULTS: From the total of 254 approvals, single arm clinical trials describing effects of 54 drugs for 72 clinical indications were evaluated. The effect size estimated was OR:2.22(CI95%:1.76-2.81) [relative risk (RR) = 1.63(95CI% 1.38-1.92)]; 53% of treatments had a lower 95% CI bound crossing the null effect. Effect size did not differ between the treatments that met the FDA requirement for conducting post-approval RCTs.

CONCLUSIONS AND RELEVANCE: Treatment effects observed in the FDA AA single-arm studies was modest and can be to ascribed to bias.
