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.



Included in the Randomzation 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.

Key features ::

  • Optional package verification number
  • Automatic shipment creation based on stock minimums
  • Batch shipping of IMP
  • Material expiry date control
  • Easy drug supplier integration into study workflow

Risk based monitoring

The Marvin EDC system supports the source data verification (SDV) process by distinguishing different risk levels for each specific study center. Customized verification rules are defined in a detailed Monitoring Plan containing different risk levels. It makes the system adaptable to the site and data handling workflow. The Monitoring Plan may also be changed and amended at any time to ensure a maximum of flexibility in a fast-changing clinical study environment. The Monitoring Plan, combined with the Sponsor‘s identification of critical data and with a close control of entered data by automated plausibility checks is an effective and cost efficient way to guarantee the safety of subjects and the quality and integrity of clinical trial data.

Key features ::

  • Flexible definition of risk levels
  • Rules to define which parts of the CRF need to be verified for which patients
  • Additional flags to document customized data review
  • SDV to do lists provide guidance for CRAs
  • SDV reports


SDTM Tabulation

The Composer supports end-to-end tabulation and allows the consistent and seamless use of a unique set of XML-based metadata from CRF design to data submission. It is an ETL solution (Extraction-Transformation-Loading), that leverages the CDISC define.xml standard and enables data managers to create CDISC SDTM-compliant datasets that are ready for reporting, analysis and submission inside the EDC database. Moreover, the Composer also supports custom tabulations such as sponsor-specific data set formats. Mapping instructions include rules for data derivations and data conversions.

Key features ::

  • Creation of define.xml

Marvin for paper implements two independent Data Entry steps and subsequent verification of discrepancies in a tabular overview. Every DDE field provides additional text and comment fields to capture all information from the paper form (e.g. data not matching the correct datatype). Data queries are triggered after the verification step.

Key features ::

  • Blind DDE: two different users enter data from paper in electronic form independent of each other
  • Dedicated review process: a third person starts a verification process in which the system identifies the discrepancies between both versions and presents them to the user to be resolved. The user interface provides an easy way to select the correct entries
  • Each item allows predefined formats as well as free text entries and a comment field for more information about the item value
  • Automated selection of matching forms, batch verification
  • Attachable ‘memos’ for internal notes and workflow support
