[en] [en] BACKGROUND: Recruitment for randomized controlled trials (RCTs) in IBD have substantially dropped over time. This study aimed to assess reasons why IBD patients are not included in sponsored multicenter phase IIb-III RCTs.
METHODS: All IOIBD members (n=58) were invited to participate. We divided barriers to participation as follow: 1) reasons patients with active IBD were not deemed appropriate for a RCT; 2) reasons qualified patients did not wish to participate; 3) reasons for screen failure (SF) in patients agreeing to participate. We assess those in a 4-week prospective study including, consecutively, all patients with symptomatic disease for whom a treatment change was required. In addition, we performed a 6-month retrospective study to further evaluate reasons for SF.
RESULTS: A total of 106 patients (60 male (56.6%), 63 Crohn's disease [CD] (59.4%)), from 10 centers across the world, were included in the prospective study. A RCT has not been proposed to 65 of them (mainly due to eligibility criteria). Of the 41 patients to whom a RCT was offered, 8 refused (mainly due to reluctance to receive placebo) and 28 agreed to participate. Among these 28 patients, 5 failed their screening and 23 were finally included in a RCT. A total of 107 patients (61 male (57%), 67 CD (62.6%)), from 13 centers worldwide, were included in our retrospective study of SFs. The main reason was insufficient disease activity.
CONCLUSION: This first multicenter study analyzing reasons for non-enrollment in IBD RCTs shown that we lose patients at each step. Eligibility criteria, the risk of placebo assignment and insufficient disease activity were part of the main barriers.
