# Comparative effectiveness and safety of tofacitinib vs. adalimumab in patients with rheumatoid arthritis: A systematic review and meta-analysis

## TL;DR

This study compares tofacitinib and adalimumab for rheumatoid arthritis, finding tofacitinib more effective in some measures without more side effects.

## Contribution

A systematic review and meta-analysis comparing the effectiveness and safety of tofacitinib and adalimumab in RA patients.

## Key findings

- Tofacitinib showed better effectiveness in ACR20, HAQ-DI, and VAS compared to adalimumab.
- No significant differences in adverse events or DAS28-CRP improvement were observed between the two drugs.
- Higher doses of tofacitinib (over 5 mg twice daily) were more effective in ACR20 improvement.

## Abstract

To provide the latest systematic review and meta-analysis comparing the effectiveness and safety of tofacitinib and adalimumab in rheumatoid arthritis (RA) patients.

A systematic search of PubMed, Embase, Web of Science, and Cochrane databases was conducted until April 2025. Randomized controlled trials and cohorts comparing tofacitinib and adalimumab in RA patients were included. Outcomes assessed were significant improvements in American College of Rheumatology (ACR) 20 improvement criteria, changes in visual analog scale (VAS) (global activity), disease activity score (DAS) 28-C-reactive protein (CRP), Health Assessment Questionnaire-Disability Index (HAQ-DI), and adverse events. Sensitivity analyses and subgroup analysis evaluated the robustness of results and heterogeneity. Data analysis was performed using Review Manager 5.4.1 and STATA 15.0.

Nine studies with 24,643 patients were analyzed. Tofacitinib showed superior effectiveness over adalimumab in ACR20 (risk ratio (RR): 1.28; 95% CI: 1.06, 1.55; P = 0.01), HAQ-DI (standardized mean difference (SMD): 0.20; 95% CI: 0.35, −0.05; P = 0.008), and VAS (SMD: 0.30; 95% CI: 0.56, −0.03; P = 0.03). No significant differences were found in adverse events (RR: 0.96; 95% CI: 0.89, 1.03; P = 0.22) or DSA28-CRP improvement (SMD: 0.02; 95% CI: 0.45, 0.02; P = 0.07). Sensitivity analyses confirmed stable outcomes for adverse events, HAQ-DI, and ACR20, but instability for VAS and DSA28-CRP. Subgroup analysis found that tofacitinib >5 mg twice daily was superior to ≤5 mg in terms of ACR20.

Tofacitinib was more effective than adalimumab in improving ACR20, VAS, and HAQ-DI, with no significant differences in adverse events or DSA28-CRP improvement.
