Comparison of the efficacy and safety of olokizumab at different dosages in patients with active rheumatoid arthritis: a network meta-analysis of randomized controlled trials

초록

ObjectiveThis study aimed to assess the relative efficacy and safety of olokizumab at different dosages in patients with active rheumatoid arthritis (RA).MethodsWe performed a Bayesian network meta-analysis to combine direct and indirect evidence from randomized controlled trials (RCTs) to examine the efficacy and safety of olokizumab administered intravenously to RA patients at 64 mg/kg every 2 or 4 weeks (Q2 or Q4W).ResultsFive RCTs comprising 2609 patients met the inclusion criteria. Both olokizumab Q2 and Q4W treatments achieved a significant American College of Rheumatology 20% response (ACR20) compared with the placebo (odds ratio [OR] 3.21, 95% credible interval [CrI] 2.53-4.09; OR 3.05, 95% CrI 2.43-3.86). However, olokizumab Q2W was associated with the most favorable surface using the cumulative ranking curve (SUCRA) for the ACR20 response rate. The ranking probability based on the SUCRA indicated that olokizumab Q2W had the highest probability of being considered the best treatment option for achieving the ACR20 response rate, followed by olokizumab Q4W, adalimumab, and placebo. The ACR50 and 70 response rates showed a similar distribution pattern to the ACR20 response rate, except that olokizumab Q4W had a higher-ranking probability than olokizumab Q2W for ACR50. The SUCRA rating likelihood of adverse events (AEs) and withdrawal due to AEs showed that a placebo was likely to be the best intervention.ConclusionBoth olokizumab Q2 and Q4W were efficacious and well-tolerated treatments for active RA.
