IDDI offers a clinical data management system from XClinical (MARVIN), allowing for both paper and electronic CRF simultaneously.
The system allows interactive double data entry of paper CRFs by IDDI data entry operators, ongoing throughout the study, as well as electronic data capture.

CRF Design

The IDDI data management team ensures an accurate and timely development of the Case Report Form or eCRF.
The concept and the layout of the CRF are created taking into account data collection requirements of the study through review of the protocol and any other supporting documentation.
IDDI expertise ensures consistency, completeness and accuracy of the CRF design, in relation to the protocol, data management requirements, planned statistical analyses and clinical appropriateness.
CRF design will result in optimizing the data collection process, including the development of the electronic version of the CRF using the appropriate software.

EDC system

IDDI recently adopted XClinical's internet based data management system MARVIN. Marvin is user-friendly, cost effective and requires a short set-up time. Since 2002, MARVIN has been used for 50 clinical trials, covering over 50,000 patients. XClinical was the first to receive the Operational Data Model compliance certificate from CDISC. MARVIN is 21 CFR part 11 and GCP compliant (full audit trail ...).



This EDC system allows complex international clinical trials to be carried out in the easiest possible manner.

MARVIN's EDC system offers some unique features:

  • Combination of Electronic Data Capture and Double Data Entry (DDE of paper CRFs) in the same study
  • Patients as user feature to integrate web-based ePRO 
  • Integration of binary data (graphics, x-rays, etc.)
  • Multi-language capabilities (including Russian and Japanese).
  • PDF printable, electronic signature and source data verification
  • Standard and custom online reports
  • Data Security: strict separation of person-identifying data and medical data
  • Minimal requirements for site's IT, and site staff training

MARVIN's DDE (Double Data Entry) system offers the following functionalities:

  • Blind DDE approach with dedicated review process
  • Each items allows:
              - pre-defined formats
              - free text and
              - investigator comments
  • Attachable "Memos" for internal notes
  • Automated and manual query workflow
