Long-term effectiveness of ustekinumab comparable to antitumor necrosis factor agents in patients with Crohn's disease.
Journal of Gastroenterology and Hepatology(2022)
摘要
BACKGROUND:Ustekinumab (UST), an antibody against the p40 subunit of interleukin-12/23, has been proven to be effective in patients with Crohn's disease (CD). However, large, long-term comparative studies of UST against anti--tumor necrosis factor (TNF) agents are lacking. We compared the effectiveness of anti-TNF agents and UST in CD patients without prior use of biologics.
METHODS:We used a large nationwide anonymized Japanese database containing administrative medical claims data and various related patient data. In a propensity score-matched cohort with similar clinical characteristics, 2-year effectiveness was compared between patients treated with infliximab or adalimumab (anti-TNF group) and those treated with UST (UST group). Primary outcomes were cumulative rates of hospitalization, surgery, and persistence.
RESULTS:Among 53 540 CD patients, 7047 were extracted for eligibility, of which 5665 were treated with an anti-TNF agent and 1382 with UST. After propensity score matching, the cumulative hospitalization rates were comparable between anti-TNF and UST groups (P = 0.85; 25.3% vs 26.5% at 1 year, 33.8% vs 39.8% at 2 years). The cumulative surgery rates were also comparable between these groups (P = 0.46; 5.5% vs 5.1% at 1 year, 8.3% vs 8.4% at 2 years). The persistence rate at 1 year was higher in UST group (90.8% vs 92.5%), and that at 2 years was higher in anti-TNF group (81.2% and 74.6%); however, there was no significant difference in the cumulative persistence rate (P = 0.55).
CONCLUSIONS:Anti-TNF agents and UST appear to have comparable effectiveness for CD patients without prior use of biologics.
