RTSM/IRT in Clinical Trials: The Complete Guide

Randomization and Trial Supply Management (RTSM) systems, also known as Interactive Response Technology (IRT), have become fundamental to modern clinical trial operations. This comprehensive guide covers everything you need to know about implementing and optimizing RTSM/IRT systems to enhance trial efficiency, simplify trial operation, maintain study integrity, and ensure regulatory compliance.

What is RTSM/IRT in Clinical Research

RTSM/IRT systems serve as the operational backbone of clinical trials, providing automated solutions for patient randomization, medication allocation, drug supply management, ensuring trial integrity. Over the past 25 years, these processes have evolved from manual, paper-based processes to sophisticated platforms supporting complex trial designs across multiple countries and sites.

Key functions include:

• Patient randomization and cohort management
• Medication allocation, drug supply management and distribution
• Real-time site and depot inventory monitoring
• Emergency unblinding procedures
• Integration with other clinical systems

The technology has evolved from early Interactive Voice Response Systems (IVRS) and Interactive Web Response Systems (IWRS) to today's advanced RTSM platforms, enabling efficient, compliant, and successful clinical trials while navigating increasingly complex study designs.
