Cure8 research brief
Why This Matters
This large real-world study found upadacitinib was associated with lower risk of treatment failure and more corticosteroid-free stability compared with several other advanced therapies for ulcerative colitis — information that may influence treatment discussions for patients and clinicians.
Who Should Pay Attention
Adults with ulcerative colitis; clinicians prescribing advanced therapies; researchers in IBD comparative effectiveness.
Study Snapshot
What To Know
A large US administrative-claims study compared real-world outcomes for several advanced therapies used to treat ulcerative colitis: infliximab, adalimumab, vedolizumab, ustekinumab, tofacitinib, and upadacitinib.
The primary outcome was time to treatment failure (IBD-related hospitalization, surgery, or a new corticosteroid prescription >90 days after starting therapy); treatment discontinuation and switching were censored.
After statistical adjustment, upadacitinib was associated with the lowest risk of treatment failure versus each other drug evaluated and had the highest proportion of quarters spent in corticosteroid-free disease stability. The study used a large US claims database and applied propensity-score weighting and competing risk methods to address confounding.
Outcomes reflect administrative claims (hospitalization, surgery, new steroid prescriptions) rather than clinical measures such as endoscopic healing or patient-reported symptoms. This is an observational, non-randomized analysis of real-world data. While the authors adjusted for many confounders, residual confounding and treatment-selection bias may remain.
The results show associations, not cause-and-effect, and may be influenced by prescribing patterns, differences in patient populations, or unmeasured disease severity.
Keep In Mind
Observational claims data can show associations but cannot prove causation. Outcomes were derived from administrative claims (hospitalizations, surgeries, steroid prescriptions) rather than direct clinical or endoscopic measures; residual confounding is possible.
