Maintaining Double-Blind in Complex Clinical Trials

This document is a technical report detailing the challenges and solutions associated with maintaining a double-blind study design in a complex clinical trial involving multiple drug types and administration routes. The report outlines the operational complexities faced by study teams, including the need to manage various treatment arms, dosing regimens, and visit schedules while preventing unblinding of participants and clinicians. It describes the investigational product as an intravenous injection and the standard of care as an oral therapy, highlighting the necessity for a robust Interactive Response Technology (IRT) system. The IRT system is presented as a solution that accommodates dynamic dose management and tracking of drug dispensation scenarios without compromising the study's blind. The report emphasizes the importance of real-time flexibility and data integrity, achieved through specific features of the IRT solution, which ultimately contributed to the efficient management of the trial and minimized operational delays.
