The Rethinking Clinical Trials (REaCT) Program: A Pragmatic Research Strategy to Improve Cancer Care for Patients, Caregivers, and Healthcare Systems.

Cancer care has become increasingly complex, expensive, and inaccessible, with patients often exposed to increased treatment-related harms for marginal benefits. Pragmatic clinical trials offer a solution by conducting real-world studies that evaluate dose optimization, toxicity, quality of life, and resource utilization. Pragmatic trials can also address the efficacy-effectiveness gap: the poorer outcomes and greater toxicity observed in everyday practice compared to those reported in many clinical trials. The Rethinking Clinical Trials (REaCT) program was designed to conduct patient-centered practice-changing research by involving patients, their families, and healthcare providers in the design of inclusive, real-world clinical trials. The REaCT process starts with surveys and systematic reviews to identify knowledge gaps and uses this information to design pragmatic clinical trials that address these deficits. Since 2014, the program has conducted 17 patient and 17 healthcare provider surveys with 2298 and 1033 responses, respectively. With these results, the program has performed 22 systematic reviews. These surveys and systematic reviews have resulted in 19 completed and 8 ongoing REaCT clinical trials that have recruited over 5000 patients from across Canada. Here, we present some of the practice-changing research conducted by the REaCT program and address challenges facing the growth of pragmatic research.
