Patient perspectives on physician conflict of interest in industry-sponsored clinical trials for multiple sclerosis therapeutics.

Background: Pharmaceutical industry financial support of physicians, physician practices, and academic departments involved in multicenter industry-sponsored clinical trials of novel therapeutic agents is a relatively new and infrequently acknowledged source of potential physician conflict of interest. Detailed disclosure of these relationships to study participants is not uniformly a part of informed consent and documentation practices.

Objective: To understand attitudes of patients with multiple sclerosis concerning disclosure of potential physician-industry conflicts of interest created by clinical trials and how such disclosures may influence study participation

Methods: An anonymous online instrument was developed.

Results: 597 people with multiple sclerosis participated in the study. The study found that detailed disclosure of conflicts of interest is important to potential participants in industry-sponsored clinical trials for multiple sclerosis therapies and that the presence of these conflicts of interest may influence patients' decisions to participate in these studies.

Conclusions: Findings from this study support a call for uniform guidelines regarding disclosure of physician-industry relationships to prospective research participants for industry-sponsored clinical trials.
