  • Operates offline (Microsoft Windows) and online (any modern browser)
  • Imports third-party vendor extensions without any modifications


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


Marvin for patients (WebPRO)

With continuously increasing requests requiring Patient Reported Outcome, Marvin provides a so-called WebPRO as an integrated module.

Key features ::

  • Integrated part of Marvin
  • Simplified user interface for optimal user acceptance
  • Configurable visibility of WebPRO data to other users such as the investigator
  • Simple account creation directly by site personnel
  • Inline reports
  • Email alerts
  • Date dependent visibility e.g. the user may enter data only during a certain period or to disallow modification of previously entered data
  • Clickable images and scales
  • Qualified identifying data handling compliant to EU legislation
  • Automatic password forgotten workflow
  • Language-specific simplified question labeling for patients


Risk based monitoring

The Marvin EDC system supports the source data verification (SDV) process by distinguishing between different levels of expected data validity for each specific study center. By setting up a detailed Monitoring Plan containing risk levels and customizable verification rules the system is ideally adaptable to the site and data handling workflow. This 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.


CDISC Tabulation

Tabulation is an integral part of the Composer. It is an ETL solution (Extraction-Transformation-Loading), which works independently of databases because it is built on the CDISC define.xml standard. It enables users to create CDISC SDTM-compliant datasets ready for submission to the authorities or for reporting purposes. Data managers can define mapping instructions for converting CDISC ODM data into CDISC SDTM or other partially de-normalized datasets.

Key features ::

  • Define.xml-based mapping of EDC/CDM datasets and SDTM datasets
  • Intuitive graphical user interface
  • Copy & paste of value-level metadata between CRF and SDTM datasets
  • Easy setup of SUPPQUAL domains
  • Creates define.xml including links to the annotated CRF
  • Independent from SAS


Marvin for paper: Double Data Entry (DDE)

Despite the fact that the majority of clinical data capture is performed electronically there is still a need for paper based data capture under specific circumstances. Typical examples are hybrid studies where the tight integration between EDC and DDE offers notable advantages. Marvin includes DDE capabilities, including free text entries, comments, review process, query and memo workflow, etc..

Key features ::

  • Blind DDE: two different users enter data from paper in electronic form independent of one another; neither can see what the other has entered or if there are any discrepancies
  • Dedicated review process: a third person starts a verification process in which the system identifies the differences between both versions and presents them to the user to be resolved
  • Each item allows predefined formats, free text, and investigator comments
  • Automated selection of matching forms, batch verification
  • Attachable ‘memos’ for internal notes and workflow support
  • Automated and manual query workflow including printing
  • Full DDE audit trail
  • Hybrid use of EDC and DDE is possible – even for a single patient (e.g. when a site switches from DDE to EDC)


CTMS – Clinical Trial Management System

Our CTMS is a special type of module including a set of customizable administrative forms, workflows, and reports that are completed and processed in the same way CRF forms are completed and processed within the Marvin EDC system. Therefore, the same mechanisms of data review, reporting and communication can be used as in Marvin.
