DiagnoSearch’s Interactive Web-based Response System (IWRS) streamlines and efficiently manages subject randomization including complex stratification and drug supply for clinical trials. Our IWRS Development Team, supported by Medical and Statistical expertise, can cater to simple as well as complex study designs and Drug Supply Management (DSM) requirements.

With a standard web browser, robust and customizable functionalities and a user-friendly interface, IWRS is a better choice for trial subject randomization and DSM. The system has been successfully utilized for trials conducted across geographies, phases and therapeutic areas and has accurately dispensed thousands of doses till date. Our IWRS solution is cost-effective, flexible and allows project specific customization.
