Introduction
Janus kinase inhibitors (JAKi) are small molecule drugs with demonstrated efficacy in inflammatory bowel disease (IBD). However, widespread utilisation may be hindered by safety concerns.
Aims & Methods
The aim of this study was to assess the risk-benefit perceptions, attitudes, and clinical practices of those using JAKi to treat IBD. A prospective, cross-sectional study was conducted using a 23-item electronic survey, which was distributed to ECCO members and delegates of the 18th Congress of ECCO, 2023, held in Copenhagen, Denmark.
Results
There were 385 respondents from 48 countries; 72% were based in tertiary referral centres and 50% were gastroenterologists with ≥10 years’ experience. JAKi were rarely used first line (8%) but were commonly used outside market authorisation (31%). Many (17%) were unconfident discussing JAKi risk-benefit profile and 7% had never prescribed JAKi despite consulting >100 unique IBD patients/year. If venous thromboembolism risks were present, 15% preferentially referred for surgery than initiate JAKi; 21% would do this even if the patient was already anticoagulated. IBD subspecialists with full GI accreditation were less likely to refer to surgery over JAKi initiation, OR 0.40 (95% CI 0.17-0.85) p=0.02. For patients relapsing on dose-reduction, 8% would switch treatment rather than dose-escalate. Conversely, 45% felt that cardiovascular safety concerns from post-marketing studies were irrelevant to IBD. Despite lack of detailed, long-term safety data, safety profiles of novel JAK1-selective drugs were perceived to be favourable to tofacitinib by most (62%).
Conclusion
The study provides unique insights from an international cohort of experienced IBD clinicians and indicates that while clinical practice appears to be in keeping with international guidance, a significant minority remain deterred by safety concerns.
