Supplementing Single-Arm Trials with External Control Arms-Evaluation of German Real-World Data.

ABSTRACT: As single-arm trials (SATs) are increasingly used in pharmaceutical research, the validity of such study designs needs to be critically assessed. We characterize the feasibility of supplementing SATs with real-world data (RWD)-derived external control arms by determining the proportion of SATs on breast cancer and amyotrophic lateral sclerosis (ALS) for which an external control arm based on RWD can be constructed. The main outcome measure is the number and percentage of trials for which all important eligibility criteria and at least one primary endpoint could be identified in one of five German RWD sources. We surveyed all SATs concerning breast cancer or ALS treatment registered in the European Union's clinical trial registers between 2004 and 2023. Ten out of 379 breast cancer SATs and
