Efficacy of anti-interleukin-17A biological agents for palmoplantar psoriasis and palmoplantar pustulosis: A network meta-analysis.

BACKGROUND

The comparative efficacy of anti-IL (interleukin)-17A biological agents in palmoplantar psoriasis (PP) and palmoplantar pustulosis (PPP) are not well established.

OBJECTIVE

To investigate the efficacy of different dosage regimens of anti-IL-17A biological agents compared with placebo in PP and PPP.

METHODS

A literature search was conducted in PubMed, clinicaltrials.gov, and Embase. Meta-analysis was performed for all outcomes of randomized controlled trials, while network meta-analysis was only performed for the primary outcome.

RESULTS

In total, 21 articles exploring the efficacy of 5 treatment options were included, 4 cohort studies were also reviewed. Meta-analysis demonstrated a statistically significant difference favoring anti-IL-17A biological agents versus placebo (OR = 6.84, 95 %[CI] [5.34, 8.76]). On-label secukinumab was identified as the most effective treatment option for patients with PP (OR = 33.50, 95 %[CI] [4.37,256.86]). PPP treated with secukinumab 300 mg showed benefit in terms of PPPASI 75 responses over 52 weeks.

CONCLUSION

IL-17A biological agents had better PP disease clearance compared with placebo and on-label secukinumab was identified as the most effective treatment option for PP patients. Secukinumab 300 mg showed benefit for PPP patients.
