Perspectives of Participants in a Multisite Canadian CCSVI Clinical Trial
Practice, Policy, and Ethics

The CCSVI hypothesis for the pathogenesis of MS incited tremendous hope in the MS community. This response was prominent in Canada where CCSVI received considerable media attention. Participants in Canada’s CCSVI trial may hold unique motivations for participating in the trial and have a vested interest in the study results.

We sought to characterize the perspectives of participants in Canada's phase I/II chronic cerebrospinal venous insufficiency (CCSVI) clinical trial prior to and after the disclosure of negative trial results.

This was a researcher-administered survey of participants in Canada's CCSVI trial (Clincialtrials.gov, NCT01864941) about their (1) motivations for participating, (2) understanding of the trial process, and (3) perspectives on the social value of the trial.

A total of 63 participants completed the survey. Participants were motivated to participate by altruism (mean score = 4.56 out of 5) and a desire to access the intervention in Canada (mean score = 3.63 out of 5). Many participants expected medical benefits, such as partial disease reversal (mean score = 3.32 out of 5). Participants felt strongly that the crossover trial design promoted fairness (mean score = 4.65 out of 5). Participants' familiarity with the CCSVI controversy increased significantly after the results were revealed (p = 0.0001). Despite negative trial results, participants still felt that the trial was an appropriate use of tax dollars (mean score = 4.68 out of 5). Many (38%) upheld the belief that further CCSVI research is necessary (responses of 4 out of 5 or higher).

There is a strong movement in science today to ensure that research agendas reflect the perspectives of stakeholders, including research participants. While previous work suggests that negative findings adversely affect trust in science, the perspectives of participants in this study demonstrate that good trial design and resilience can prevail over expected tensions.
