Matching-Adjusted Indirect Comparison Between Risankizumab and Ustekinumab for Induction and Maintenance Treatment of Moderately to Severely Active Crohn’s Disease
Advances in therapy(2023)
摘要
Introduction Risankizumab (RZB) and ustekinumab (UST), interleukin (IL)-23 and IL-12/23 inhibitors, respectively, are approved treatments for moderately to severely active Crohn’s disease (CD); direct comparison between the two is ongoing. We indirectly compared efficacy of RZB versus UST using data from phase 3 trials (RZB: NCT03104413; NCT03105128; NCT03105102; UST: NCT01369329; NCT01369342; NCT01369355). Methods Matching-adjusted indirect comparison was conducted using individual patient-level data from RZB trials and published aggregated data from UST trials. During induction, patients received RZB 600 mg intravenous (IV) at weeks 0, 4, and 8 or a single dose of UST 6 mg/kg IV at week 0. During maintenance, patients received RZB 180 or 360 mg subcutaneous (SC) or UST 90 mg SC every 8 or 12 weeks to 52 weeks. Outcomes included proportion of patients achieving Crohn’s Disease Activity Index (CDAI) response (decrease of ≥ 100 points or total score < 150) or remission (CDAI ≤ 150) and endoscopic improvement (measured by the Simple Endoscopic Score in CD [SES-CD]; response, ≥ 50% reduction from baseline; remission, SES-CD ≤ 2) following induction/baseline. Results Higher proportions of patients achieved clinical and endoscopic outcomes with RZB vs. UST induction treatment, resulting in significantly ( p ≤ 0.05) greater percent differences (95% confidence intervals) between groups for CDAI remission (15% [5%, 25%]) and endoscopic response (26% [13%, 40%]) and remission (9% [0%, 19%]). Following maintenance, rates of CDAI remission were similar (range − 0.3% to − 5.0%) for RZB vs. UST. Differences for endoscopic response and remission ranged from 9.3% to 27.7% and 11.6% to 12.5%, respectively; differences were significant ( p < 0.05) for endoscopic response for both doses of RZB compared to UST 12-week dosing. Conclusions This indirect comparison demonstrated higher rates of clinical and endoscopic outcomes during induction for RZB compared to UST; CDAI remission following maintenance was comparable. Direct comparisons of RZB and UST are warranted to validate these findings.
