Background And Objective:
Plaque psoriasis is commonly treated topically with glucocorticoids and vitamin D derivatives. However, potential side effects such as skin atrophy underscore the need for safe and effective alternative topical therapies. Recently, the US Food and Drug Administration (FDA) and Health Canada approved roflumilast 0.3% cream as an option for treating this disease. A systematic review and meta-analysis of randomized controlled trials (RCTs) was conducted to assess the efficacy and safety of topical roflumilast 0.3% compared with vehicle for plaque psoriasis.
Methods:
PubMed, Embase, ClinicalTrials.gov, and Cochrane databases were searched from inception to 1 May 2024, assessing the outcomes of Investigator's Global Assessment (IGA) or body-IGA success (clear or almost clear status plus an at least 2-grade improvement from baseline), Psoriasis Area and Severity Index (PASI)-50, PASI-75, PASI-90, intertriginous-IGA success (clear or almost clear status on the intertriginous-IGA plus an at least 2-grade improvement from baseline), and adverse events (AEs). Statistical analysis was performed using Review Manager, R software, and RStudio. Heterogeneity was determined using the Cochran Q test and I2 statistics.
Results:
Four RCTs were included, comprising a total of 1403 patients, of whom 885 (63.1%) received topical roflumilast 0.3% and 518 (36.9%) received vehicle. At week 8, the achievement of IGA or body-IGA success was significantly higher among those treated with topical roflumilast than in the vehicle group [relative risk (RR) 5.07; 95% confidence interval (CI) 3.55-7.23; p < 0.01]. Similar findings were observed at week 8 for PASI-50 (RR 2.73; 95% CI 2.27-3.29; p < 0.01), PASI-75 (RR 4.48; 95% CI 2.26-8.89; p < 0.01), and PASI-90 (RR 5.61; 95% CI 2.57-12.25; p < 0.01). Corresponding outcomes were found at weeks 2, 4, and 6. Additionally, a higher percentage of patients treated with topical roflumilast 0.3% once daily achieved intertriginous-IGA success, compared with those receiving vehicle, at week 8 (71.9% versus 20.5%; RR 3.32; 95% CI 2.11-5.22; p < 0.01), with similar findings at weeks 2, 4, and 6. While a significant difference was observed in the overall incidence of AEs between the topical roflumilast and vehicle groups, there was no difference in treatment-related AEs, serious AEs, or AEs leading to study discontinuation.
Conclusion:
These findings support the superiority of topical roflumilast 0.3% over vehicle and suggest its use as a valuable asset for the treatment of plaque psoriasis.
