Abstract

Background: The current therapy of Rheumatoid Arthritis (RA) is confronted with many challenges such as inadequate response, infection, and treatment failure.

Aim and Objective: The main objective was to assess the efficacy and safety of tocilizumab (TCZ) in subjects with RA using the available evidence from published randomized controlled trials.

Methods: The current systematic review was performed on nine randomized controlled trials from 2002 to 2016 for TCZ in subjects with rheumatoid arthritis. The primary outcomes were the clinical improvement in American College Rheumatology 20% (ACR20) or Disease Activity Score remission (DAS28), in addition to other outcomes such as ACR50 and ACR70 in the intention-to-treat population.

Results: We have conducted a systematic review on nine randomized controlled trials, with 4129 [100%] enrolled, of which 3248 [78.7%] were on the intention-to-treat. 2147 (66.1%) were treated with TCZ and 1101 (33.9%) have had received placebo or methotrexate or other conventional Disease- Modifying Anti-rheumatic Drugs (cDMARD) or biologic Disease-Modifying Anti-rheumatic Drugs (bDMARDs). In subjects taking TCZ with or without concomitant methotrexate, compared to placebo, subjects treated with TCZ 4 or 8 mg/kg were substantially and statistically significantly more likely than placebo or methotrexate to achieve the ACR20 and/or DAS28. There were no statistically significant differences in serious adverse events such as serious infection; however, subjects on TCZ were more likely to have increased lipid profiles.

Conclusion: TCZ mono-therapy or in combination with methotrexate is valuable in diminishing rheumatoid arthritis disease activity and improving disability. Treatment with TCZ was associated with a significant surge in cholesterol levels but no serious adverse effects. Randomized clinical trials with safety as the primary outcome are warranted to report these safety issues.

Keywords: Rheumatoid Arthritis (RA), Interleukin-6 inhibitor (IL-6), Tocilizumab (TCZ), randomized clinical trials, placebo, comparator, safety, efficacy.
