What we have achieved

EFFECTS has established the trial management, IT systems to manage web-based randomisation, drug allocation, stock control, follow-up, data collection, verification, and an electronic follow-up system (eCRF). In total, the Chief Investigator and Trial Manager, have met almost 500 possible investigators from the whole country. One major obstacle has been the lack of Good Clinical Practice (GCP) training. Hence, we have been forced to arrange ten separate half day training sessions in GCP. In total, we have certified almost 150 investigators in GCP. Further, we have completed five investigator meeting, the latest in October 2017 with 53 participants from the whole of Sweden. We now know important aspects of recruitment, medication adherence, questionnaire completion and follow-up rates. All systems are fine-tuned and running smoothly. We have also registered three PhD students for the EFFECTS study.

Organisation, randomisation, clinical data management system and website

  • Established a Clinical Trial Unit that consists of a Chief Investigator (Erik Lundström), Trial Manager (Eva Isaksson) and Trial Manager Assistant (Nina Greilert).
  • Established a Trial Steering Committee and Data Monitoring Committee.
  • Established a randomisation system with a minimisation algorithm.
  • Established an electronic clinical data management system that captures all our variables throughout the study.
  • Set up a website.

Steering Committee

Prof Katharina Stibrand-Sunnerhagen (chair), Prof Bo Norrving, Prof Per Wester, Prof Håkan Wallén, docent/psychiatrist Björn Mårtensson, statistician Per Näsman, Chief Investigator Erik Lundström and Trial Manager Eva Isaksson.

Data Monitoring Committee

Prof Kjell Asplund (chair), Anders Ljungström (statistician), Docent Kerstin Hulter-Åsberg.

Progress of the study

We have finished recruiting. Last-patient-in was 28 June 2019

High quality of data

We have high data quality. At our primary outcome, we have a response rate of over 98%. (Preliminary data). Our monitor reports also show good quality of source data.
