Abstract:
Investigator-initiated trials (IITs) are clinical trials in which the clinician is both the sponsor and the investigator. IITs have also been developed to test strategies designed to optimize existing therapies or treatment approaches that may not be supported by industry sponsors or may be too novel to gain the consensus to be supported by cooperative groups. The role of the investigator is comprehensive and includes protocol development, securing funding for the administration of the trial, recruitment and monitoring of subjects, and assurance for the protection of human subjects. We will briefly review the importance of surgeons in developing IITs and provide insights into logistical barriers from conception to completion of the trial.
Insights
Investigator-initiated trials (IITs) empower clinicians to lead research, optimizing therapies when industry or cooperative groups lack support. Surgeons play a key role in developing these vital clinical trials.
