Objective: Evaluation of the effectiveness and safety of secukinumab and ixekizumab in active ankylosing spondylitis (AS) patients. Methods: A Bayesian network meta-analysis was conducted using direct and indirect data from five randomized controlled trials that examined the efficacy and safety of secukinumab 150 mg every 4 weeks and ixekizumab 80 mg every 2 weeks (IXEQ2W) or every 4 weeks (IXEQ4W) in active AS patients. Results: Data from 1433 patients were analyzed. The Assessment of Spondyloarthritis International Society evaluation 20% response rates (ASAS20) were significantly higher with secukinumab 150 mg, IXEQ2W, IXEQ2W, and adalimumab 40 mg (odds ratio [OR] 2.75, 95% Bayesian credible interval [CrI] 2.04–3.69; OR 2.59, 95% CrI 1.69–3.98; OR 2.45, 95% CrI 1.60–3.75; and OR 1.94, 95% CrI 1.13–3.37, respectively) compared to the placebo group. Efficacies of secukinumab and ixekizumab were numerically higher compared to adalimumab 40 mg, although there was no significant difference in the ASAS20 response rates. The ASAS40 response rate showed a pattern of distribution similar to the ASAS20 response rate, with the exception of the ixekizumab group, which was associated with the most favorable surface under the cumulative ranking curve (SUCRA) for the ASAS40 response rate. Based on the SUCRA rating, secukinumab 150 mg had the highest probability of being the best ASAS20 response rate therapy, followed by IXEQ2W, IXEQ4W, adalimumab 40 mg, and placebo. There was no significant difference between the treatments regarding the number of serious adverse events (SAEs). Conclusion: Secukinumab and ixekizumab were effective in active AS treatment, without the risk of SAEs.
