Comparative Efficacy (DAS28 Remission) of Targeted Immune Modulators for Rheumatoid Arthritis: A Network Meta-Analysis.

ABSTRACT:

Introduction

The objective of this study was to evaluate the relative efficacy of targeted immune modulators (TIMs) in TIM-naïve/mixed populations (≤ 20% TIM-experienced) and TIM-experienced (> 20% TIM-experienced) adults with moderate-to-severe rheumatoid arthritis with an inadequate response to or intolerance of conventional disease-modifying antirheumatic drugs (cDMARDs).

Methods

A fixed-effects Bayesian network meta-analysis (NMA) was performed using published study-level data from 41 randomized controlled trials (RCTs) identified from two recent systematic literature reviews conducted by the Institute for Clinical and Economic Review, and two additional phase III trials for filgotinib (FINCH-1, FINCH-2). RCTs that compared TIMs with each other, cDMARD therapy, or placebo were included. Treatments included Janus kinase (JAK) inhibitors, tumor necrosis factor α inhibitors (TNFi), and other non-TNFi therapies. Efficacy was defined as achieving remission with a DAS28 score < 2.6 at 12 and 24 weeks.

Results

In the 12-week analysis for the TIM-naïve/mixed population, all TIMs combined with cDMARD therapy were significantly more likely to achieve remission compared with a cDMARD alone, with intravenous tocilizumab showing a substantially greater magnitude of effect (odds ratio 19.36; 95% credible interval 11.01-38.16). Similarly, in the 24-week analysis, intravenous and subcutaneous tocilizumab showed the highest odds ratio of achieving DAS28 remission compared with cDMARD therapy. Similar trends were observed for the analyses on monotherapy or TIM-experienced population.

Conclusions

This NMA demonstrated that tocilizumab is associated with a greater likelihood of remission (DAS28 < 2.6) at 12 and 24 weeks compared with most other TIMs, including new JAK inhibitors, when used in combination with a cDMARD or as monotherapy among TIM-naïve/mixed or TIM-experienced populations.

Project description:IntroductionJanus kinase (JAK) inhibitors are a class of targeted therapies for rheumatoid arthritis (RA) with established clinical efficacy. However, little is known about their efficacy compared with each other. This network meta-analysis (NMA) estimated the comparative efficacy of JAK inhibitors currently approved for RA.MethodsA targeted literature review was conducted for phase III randomized controlled trials (RCTs) evaluating the efficacy of three approved JAK inhibitors (tofacitinib, baricitinib, and upadacitinib) as monotherapy or combination therapy among patients with moderate-to-severe RA who had inadequate response to conventional synthetic disease-modifying antirheumatic drugs (csDMARD-IR). Using Bayesian NMA, American College of Rheumatology (ACR) 20/50/70 responses and clinical remission (defined as DAS28-CRP < 2.6) were evaluated separately at 12 and 24 weeks.ResultsEleven RCTs were identified and included in the NMA. All JAK inhibitors demonstrated significantly better efficacy than csDMARD. Among combination therapies, upadacitinib 15 mg had the highest 12-week ACR50 responses (median [95% credible interval]: 43.4% [33.4%, 54.5%]), followed by tofacitinib 5 mg (38.7% [28.6%, 49.8%]), baricitinib 2 mg (37.1% [25.0%, 50.6%]), and baricitinib 4 mg (36.7%, [27.2%, 47.0%]). Similar results were observed for ACR20/70 and at week 24. Upadacitinib 15 mg + csDMARD was also found to have the highest clinical remission rates at week 12 (29.8% [16.9%, 47.0%]), followed by tofacitinib 5 mg (24.3%, [12.7%, 40.2%]), baricitinib 4 mg (22.8%, [11.8%, 37.5%]), and baricitinib 2 mg (20.1%, [8.6%, 37.4%]). Similar results were seen at week 24. Among monotherapies, upadacitinib had a higher ACR50 response (38.5% [25.3%, 53.2%]) than tofacitinib (30.4% [18.3%, 45.5%]). The differences in efficacy measures were not statistically significant between the JAK inhibitors.ConclusionsThe NMA found that upadacitinib 15 mg once daily had numerically higher efficacy in terms of ACR response and clinical remission among approved JAK combination therapies and monotherapies for csDMARD-IR patients with RA.
