Cure8 research brief
Why This Matters
Patients and clinicians often wonder whether starting advanced therapies earlier after diagnosis affects how long patients stay on those drugs. This study suggests early use is common and may be associated with better persistence, which could influence treatment planning and discussions about early escalation.
Who Should Pay Attention
Newly diagnosed adults with Crohn's disease, patients considering or already on biologic/targeted therapies, gastroenterologists, and researchers studying early intervention strategies in IBD.
Study Snapshot
What To Know
The report enrolled patients aged ≥16 with newly diagnosed Crohn's disease who were advanced-therapy–naïve and followed real-world treatment choices. Of 672 patients, 498 (74%) started an advanced therapy; 60% began treatment within one year of diagnosis.
Three-year persistence estimates were: infliximab ~77.5%, adalimumab ~75.7%, ustekinumab ~79.8%, and vedolizumab ~49.0%. The authors used Kaplan–Meier and multivariable Cox models, and compared early versus delayed initiation using propensity score weighting.
Early initiation tended toward greater persistence versus delayed start (hazard ratio 0.61) but did not reach conventional statistical significance (P = .067). The registry is prospectively registered (UMIN000032237) and this entry reports an interim analysis of real-world treatment patterns and persistence.
Keep In Mind
This is an interim analysis from a registry (abstract-level content). Results are observational and reflect real-world prescribing and persistence; they do not establish causality. The early-versus-delayed comparison was adjusted but did not reach statistical significance, and the authors recommend confirmation in other prospective studies.
