P952 Why do patients with Inflammatory Bowel Disease Take Part in Pharmaceutical Clinical Trials? A qualitative study of Clinical Trial Participants

Abstract

Abstract Background Recruitment rates to clinical trials in inflammatory bowel disease (IBD) continue to decline. A better understanding of motivations to participate as well as recommendations to reduce barriers to enrolment from a patient perspective may assist in design of future clinical trials. Methods We developed a 32-item electronic questionnaire to explore motivations, experiences and recommendations of patients with IBD, who have participated in pharmaceutical clinical trials in a tertiary centre in Canada. Results We distributed a total of 82 emails with surveys based on the patient details available to the study team. Using the DillMan Total Design Survey method, participants were followed up one week after the initial email with a reminder phone-call and we received 46 responses (56.1% response rate). Participants were mostly, male (58.7%), non-Hispanic white (93.5%), with a mean age of 45.5 years (SD 10.9). Most participants decided to participate in a clinical trial to benefit future patients with IBD (63.0%). Self-reported knowledge of the possibility of being assigned to placebo on a scale from 0 (no knowledge) to 100 (extremely knowledgeable) was a median of 100 (IQR 100-100) (Table 1). Half of participants (50.0%) reported they were worried about the possibility of receiving placebo, although the majority (63.0%) understood they could improve on placebo. The most challenging aspect reported was the number and length of questionnaires (32.6%), as well of the number of colonoscopies (30.4%). Strategies to increase enrolment recommended by participants were reduction in the chance of receiving placebo (43.5%), facilitating inclusion of patients who have failed multiple therapies (43.5%), allowing virtual visits (39.1%), including subtypes of disease that have traditionally been excluded in clinical trials (e.g., ostomies, fistula) (34.8%), and improving outreach to underrepresented populations (28.3%) (Figure 1). The vast majority (80.4%) reported their experience of participation to be better than expected and would recommend taking part in a clinical trial to other patients with IBD (97.8%). Conclusion Patients with IBD who took part in pharmaceutical trials reported a high level of satisfaction overall. The top three recommendations from patients to improve clinical trial design were reducing the chance of receiving placebo, allowing inclusion of patients who have failed multiple therapies and allowing for virtual visits to reduce travel burden to the clinical trial site. These results should help inform the design of patient centric clinical trials in IBD.
