Although the current state of this research is insufficient to draw robust conclusions, these early results suggest that delaying the close of enrollment periods reduces the probability of termination of a trial. The successful completion of Phase III clinical trials is crucial for bringing new treatments to market. This research provides insights into how enrollment management impacts trial outcomes. While the preliminary results suggest that delaying the close of enrollment periods may reduce termination probability, the analysis reveals significant variation across disease categories and highlights important methodological challenges. The primary limitation that must be addressed before drawing a strong conclusion is that of insufficient data. This takes two forms. The first is the small sample size. To overcome this requires an improved data matching approach and a revised data scraper. The second is creating a model of enrollment that can be used to address the causal identification issue from the joint determination of enrollment statuses and elapsed durations of trials. Despite these limitations, this work establishes a framework for analyzing operational versus strategic factors in clinical trial completion. The approach developed here can be extended with additional data to provide more definitive guidance on enrollment management strategies. Further research in this direction could help reduce operational barriers to trial completion or estimating the impact policies may have through operational channels. Ultimately this work will hopefully support more efficient drug development and increased market competition. \end{document}
