Level of evidence: B

Apremilast treatment at the dose of 30 mg twice daily, when compared to placebo, may increase the proportion of patients with active psoriatic arthritis achieving the ACR20 response at week 16 to 24 from approximately 20% to 40%.

It may be, that treatment with apremilast causes more adverse events than placebo, but they are mostly mild, and severe adverse events may not be common.

Ref. Study type Population Intervention and comparison Outcomes Risk of bias
MA=meta-analysis, RCT=randomized controlled trial. ARC20=20% improvement in signs and symptoms of psoriatic arthritis according to American College of Rheumatology criteria, APR=apremilast

Secondary: ACR50, ACR70, and PASI50-75-90 at week 16, serious adverse events

Reference Comments
APR=apremilast
«Ramiro S, Smolen JS, Landewé R ym. Pharmacological...»1 Systematic review and meta-analysis. At the time of the analysis only 1 study had been published as full text article (PALACE-1), the others as abstracts (PALACE 2-4). PALACE 1 risk of bias moderate due to only per-protocol analysis, unclear sequence generation and allocation concealment.
«Strand V, Elaine Husni M, Betts KA ym. Network met...»2 The network analysis is based on same studies as meta-analysis [1]. Risk of bias assessment is not reported. Risk of bias is moderate due to unclear sequence generation and allocation concealment. Sponsored by Celgene Corporation.
«Nash P, Ohson K, Walsh J ym. Early and sustained e...»3 Phase IIIb RCT. Patients had to discontinue their csDMARD at least 1 day before baseline assessment. Patients were eligible for early escape at week 16 if no improvement by >10% in swollen joint count and tender joint count. At week 24 placebo group switched to apremilast. 84.5% completed week 24.
«Mease PJ, Gladman DD, Gomez-Reino JJ ym. Long-Term...»4 Randomization in 3 groups (APR 30 mg, APR 20 mg, placebo) lasted for 24 weeks. Thereafter, placebo patients were randomized to receive APR 30 or 20 mg up to 54 weeks. After 54 weeks, patients continued on medication and were followed up to 156 weeks. Here, the results on placebo controlled phase (24 weeks) are presented.
