Real-World Effectiveness of Vedolizumab Dose Escalation in Patients With Inflammatory Bowel Disease: A Systematic Literature Review.

ABSTRACT:

Background

Vedolizumab is a gut-selective anti-lymphocyte trafficking agent approved for the treatment of moderate to severely active inflammatory bowel disease (IBD: ulcerative colitis [UC] and Crohn's disease [CD]).

Methods

A systematic literature review (SLR) of real-world studies was conducted to assess the effectiveness of dose escalation of vedolizumab every 8 weeks (Q8W) during maintenance treatment to achieve a response in patients who were either vedolizumab responders experiencing secondary loss of response (SLOR) or non-responders. MEDLINE and EMBASE databases were searched from January 2014 to August 2021.

Results

Screening of SLR outputs identified 72 relevant real-world study publications featuring dose escalation of vedolizumab maintenance therapy. After qualitative review, ten eligible studies (9 articles, 1 abstract) were identified as reporting clinical response and/or clinical remission rates following escalation of intravenous vedolizumab 300 mg Q8W maintenance dosing to every 4 weeks (Q4W) maintenance dosing in adult patients with UC/CD (≥10 patients per study). Overall, 196/395 (49.6%) patients with IBD had a response within 54 weeks of vedolizumab maintenance dose escalation. Although definitions for clinical response/remission varied across the 10 studies, clinical response rates after escalated vedolizumab Q8W maintenance dosing ranged from 40.0% to 73.3% (9 studies) and from 30.0% to 55.8% for remission (4 studies) over a range of 8 to <58 weeks' follow-up.

Conclusions

This synthesis of real-world effectiveness data in vedolizumab-treated patients with IBD indicates that approximately half were able to achieve or recapture clinical response after escalating vedolizumab maintenance dosing.

Project description:IntroductionBelimumab is a recombinant human monoclonal antibody that binds to soluble B-lymphocyte stimulator and inhibits its biological activity. Since receiving approvals for the treatment of systemic lupus erythematosus (SLE), several observational studies have investigated the effectiveness of belimumab in the real-world setting. This study reports a systematic review and meta-analysis of the literature to evaluate the real-world effectiveness of belimumab for the treatment of SLE.MethodsA literature search following PRISMA Guidelines and limited to studies in English was performed (2014-2020) to identify relevant studies reporting effectiveness outcomes of belimumab in patients with SLE. A modified version of the Newcastle-Ottawa Scale was used to assess study quality. Outcomes, including SLE Disease Activity Index (SLEDAI) score, prednisone-equivalent use, and SLE flare were pooled and analyzed using statistical aggregation methods.ResultsThe literature search identified 514 articles for initial review. Of these, 17 articles were suitable for data extraction and summary. Baseline characteristics of patients in real-world studies were generally similar to those of relevant clinical trials, including age, sex, disease duration, SLEDAI score, and prednisone-equivalent use. Real-world use of belimumab was associated with reductions in SLEDAI score (mean baseline score to month 6: 10.1-4.4; 57% reduction), prednisone-equivalent dosing (mean baseline dose to month 6: 12.1 mg/day to 6.9 mg/day; 43% reduction), and flare frequency (12 months prior to belimumab to 12 months after belimumab: 1.15-0.39 mean flares per patient per year; 66% reduction). Long-term data (up to 2 years post-treatment initiation) for SLEDAI score and prednisone-equivalent dose indicated that improvements in both outcomes continue over time among patients remaining on therapy.ConclusionsIn the real-world setting, observed outcomes with belimumab for the treatment of SLE are consistent with those reported from randomized clinical trials. Improvements persist long-term for SLEDAI activity and prednisone-equivalent use with belimumab.
