Managing a clinical trial involves dozens of sites, thousands of patients, and real-time data flows. In this context, RTSM (Randomization and Trial Supply Management) has become an essential tool. By combining patient randomization and treatment supply management, this system enables research teams to improve reliability and efficiency throughout the study.
What is RTSM?
RTSM assigns each participant to a treatment arm according to a methodology defined in the protocol (e.g., simple, stratified, or block randomization). Its objectives are to ensure:
- No selection bias
- Balance between groups
- Reproducibility and traceability of allocations
RTSM also manages the logistics of investigational products:
- Inventory management by site and country
- Automatic resupply triggers
- Tracking of batches, expiration dates, and statuses
- Allocation of kits to patients in line with randomization
An RTSM acts as a real-time transactional system, interconnected with other components (EDC, ePRO, CTMS) to:
- Secure treatment assignment
- Prevent stock shortages
- Ensure protocol compliance
RTSM vs IWRS: what’s the difference?
RTSM is often confused with IWRS (Interactive Web Response System). While both systems share similar functionalities, their scope differs:
- IWRS focuses on interactive communication between sites and sponsors, mainly for randomization.
- RTSM is more comprehensive: it also includes supply chain management, inventory tracking, and coordination between depots and clinical sites.
In short, RTSM encompasses IWRS functionalities while adding a supply management layer.
