Long-Term Efficacy and Safety of Ozanimod in Moderately to Severely Active Ulcerative Colitis: Results From the Open-Label Extension of the Randomized, Phase 2 TOUCHSTONE Study.

ABSTRACT:

Background and aims

This analysis examined the long-term safety and efficacy of ozanimod in patients with moderately to severely active ulcerative colitis [UC] with ≥ 4 years of follow-up in the phase 2 TOUCHSTONE open-label extension [OLE].

Methods

Patients receiving placebo or ozanimod HCl 0.5 mg or 1 mg during the double-blind period could enter the OLE [ozanimod HCl 1 mg daily]. Partial Mayo score [pMS] clinical response and remission were assessed through OLE week 200 and summarized descriptively using observed cases [OC] and non-responder imputation [NRI]. Endoscopy was required at OLE week 56 and the end of treatment. Parameters associated with endoscopy were summarized at weeks 56 and 104 [OC], and week 56 [NRI]. C-reactive protein and faecal calprotectin were assessed. Adverse events were monitored throughout the study.

Results

Of 197 patients receiving double-blind treatment, 170 entered the OLE. Discontinuation rates were 28% at year 1 and 15-18% annually through year 4. Partial Mayo measures indicated clinical response and remission rates at OLE week 200 of 93.3% and 82.7%, respectively, using OC and 41% and 37% with the more conservative NRI analysis. At weeks 56 and 104, respectively, histological remission rates were 46.3% and 38.5%, and endoscopic improvement rates were 46.4% and 46.5% [OC]. No new safety signals were identified during ≥ 4 years of follow-up.

Conclusions

There was a high rate of continued study participation and long-term benefit with ozanimod HCl 1 mg daily based on clinical, histological and biomarker measures in patients with moderately to severely active UC in the TOUCHSTONE OLE. [NCT02531126].

Project description:BackgroundDue to wide-ranging impacts of Ulcerative Colitis (UC), regulatory authorities emphasize the importance of including validated patient-reported symptom severity measures in clinical trials.AimTo describe the development and validation of the Ulcerative Colitis-Symptom Questionnaire (UC-SQ).MethodsThe UC-SQ was developed in a qualitative study involving a targeted literature review, semi-structured concept elicitation interviews, and combined concept elicitation/cognitive interviews. Measurement properties, including item-level analyses, factor structure, reliability, validity, responsiveness, and clinically meaningful change were evaluated using data from a phase 2b, randomized trial in adults with UC (N = 113).ResultsFourteen symptom concepts were elicited across 22 interviews, with saturation at the fifth interview. Twenty-two items were unmodified as cognitive interview participants interpreted underlying concepts correctly. Instructions were clear and items were relevant, with appropriate response options and recall periods. Reduction to 17 items was completed prior to psychometric testing. Two items (joint pain/constipation) did not contribute to reliability in initial testing and were included as non-scored items. The 15-item UC-SQ showed evidence of internal consistency (α = 0.86) and test-retest reliability (intraclass correlation coefficient = 0.88). The UC-SQ discriminated by disease severity as defined by Mayo and Inflammatory Bowel Disease Questionnaire scores (p < 0.0001). Convergent validity was supported by strong correlations with criterion measures. The UC-SQ was responsive in patients indicating change in other measures. A 10-point decrease from baseline indicated within-patient meaningful improvement.ConclusionsThe UC-SQ is reliable, valid and responsive, with a 10-point improvement estimating within-patient clinically meaningful improvement. The tool is fit-for-purpose as a key endpoint in pivotal UC trials.

Project description:BackgroundWith an increasing number of therapeutic options available for the management of ulcerative colitis (UC), the variability in treatment and prescribing patterns is not well known. While recent guidelines have provided updates on how these therapeutic options should be used, patterns of long-term use of these drugs over the past 2 decades remain unclear.MethodsWe analyzed a retrospective, nationwide cohort of more than 1.7 million prescriptions for trends in prescribing behaviors and to evaluate practices suggested in guidelines relating to ordering biologics, step-up therapy, and combination therapy. The primary outcome was 30-day steroid-free remission and secondary outcomes included hospitalization, cost, and additional steroid usage. A pipeline was created to identify cohorts of patients under active UC medical management grouped by prescribing strategies to evaluate comparative outcomes between strategies. Cox proportional hazards and multivariate regression models were utilized to assess postexposure outcomes and adjust for confounders.ResultsAmong 6 major drug categories, we noted major baseline differences in patient characteristics at first exposure corresponding to disease activity. We noted earlier use of biologics in patient trajectories (762 days earlier relative to UC diagnosis, 2018 vs 2008; P < .001) and greater overall use of biologics over time (2.53× more in 2018 vs 2008; P < .00001) . Among biologic-naive patients, adalimumab was associated with slightly lower rates of remission compared with infliximab or vedolizumab (odds ratio, 0.92; P < .005). Comparisons of patients with early biologic initiation to patients who transitioned to biologics from 5-aminosalicylic acid suggest lower steroid consumption for early biologic initiation (-761 mg prednisone; P < .001). Combination thiopurine-biologic therapy was associated with higher odds of remission compared with biologic monotherapy (odds ratio, 1.36; P = .01).ConclusionsAs biologic drugs have become increasingly available for UC management, they have increasingly been used at earlier stages of disease management. Large-scale analyses of prescribing behaviors provide evidence supporting early use of biologics compared with step-up therapy and use of thiopurine and biologic combination therapy.
