Introduction: In ulcerative colitis (UC), anti-TNF agents often are first-line biologic therapy. Switching to a different class of biologics (ustekinumab, vedolizumab) or cycling to another anti-TNF agent (adalimumab, infliximab, golimumab) is necessary if an initial anti-TNF fails. Real-world persistence in patients with UC who switch or cycle from an anti-TNF agent was compared.

Methods: Adults with UC treated with an anti-TNF, who switched or cycled (index date) between 10/21/2019 and 03/02/2022, were selected from the IQVIA PharMetrics^®Plus database. Patients had ≥12 months of continuous insurance eligibility before the first anti-TNF without UC-indicated biologics or advanced therapies. During the 12-months before the index date (baseline period), patients had no other immune disorders and discontinued the first anti-TNF. Baseline characteristics were balanced using inverse probability of treatment weights. Persistence on index biologic was defined as no therapy exposure gaps >120 days (ustekinumab, vedolizumab, infliximab) or >60 days (adalimumab, golimumab) between days of supply. Composite endpoints were persistence and being corticosteroid-free (< 14 consecutive days of corticosteroids supply after day 90 post-index), and persistence while on monotherapy (no immunomodulators/non-index biologics/advanced therapies). Endpoints were assessed with weighted Kaplan-Meier and Cox proportional hazards models at 12 months after maintenance phase start.

Results: The switch and cycle cohorts included 488 and 129 patients, respectively; baseline characteristics were well balanced (Table 1). At 12 months after maintenance phase start, proportions of persistent patients and patients persistent on monotherapy were significantly higher in the switch versus the cycle cohort (Figure 1). In the switch cohort, the rate of persistence was 53% higher (hazard ratio [HR]: 1.53; 95% confidence interval [CI]: 1.10-2.12), the rate of persistence and being corticosteroid-free 23% higher (HR: 1.23; 95% CI: 0.93-1.63), and the rate of persistence while on-monotherapy was two times higher (HR: 2.18; 95% CI: 1.64-2.92) than in the cycle cohort.

Discussion: Patients with UC who switched from an anti-TNF agent to a different class of biologic were more persistent than patients who cycled to another anti-TNF agent. Findings may aid physicians whose patients experience treatment failure on the first anti-TNF agent.
