IWRS Randomization

The Randomization System is an IWRS (Interactive Web Response System) built into Marvin; therefore no interface to another external system is required. The system supports open or double-blind, multi-strata, multi-group randomization based on a block list or a widely configurable range of algorithms like variance minimization. The block-based randomization can be set up by uploading the configuration files via the web interface. The randomization list can include blocks of any size linked to an unlimited number of therapy groups and stratification parameters. The parameters for the configurable algorithms within the Marvin randomization system are configured using the Composer. For every patient entered in the study and fulfilling all necessary criteria, Marvin calculates the therapy group assignment.


Logistics (Drug Management)

Included in the Randomization System is also a materials accountability module with (investigational) medical product stock management inventory and logistics. Shipments of materials from a central stock to different sites is managed via a web-based workflow including optional package verification numbers. Shipments can be generated automatically or manually. Then Marvin assigns investigational products to patients according to their (blinded) therapy group.
