In a landmark study, investigators have delved into the comparative effectiveness and safety of novel topical drugs for psoriasis, a chronic immune-mediated skin disease affecting millions worldwide. The study focused on topical therapeutic aryl hydrocarbon receptor (AhR)-modulating agents (TAMA), topical phosphodiesterase type 4 (PDE-4) inhibitors, and topical janus kinase-signal transducer and activator of transcription (JAK-STAT) inhibitors.

A rigorous systematic review and network meta-analysis (NMA) were conducted, drawing from a pool of eligible randomized controlled trials (RCTs). The primary efficacy assessment criteria were centered around the percentage of subjects attaining a Physician's Global Assessment 0/1 (PGA response), with a secondary criterion being a ≥75% drop in Psoriasis Area and Severity Index (PASI 75). Safety was evaluated through adverse events assessment.

Among the six novel topical drugs scrutinized, the odds of attaining both PGA response and PASI 75 were notably greater with all regimens of TAMA and Roflumilast cream compared to the vehicle. However, it was observed that TAMA illustrated a greater likelihood of adverse events, signaling a potential trade-off between effectiveness and safety. In contrast, no profound differences were witnessed between topical JAK-STAT inhibitors and the vehicle, except for 1% Ruxolitinib ointment once daily.

Hence, TAMA exhibited a robust therapeutic effect but at a relatively lower safety threshold. On the other hand, Roflumilast cream emerged as a promising contender with both high efficacy and safety. This groundbreaking research not only provides crucial insights into the treatment of psoriasis but also opens avenues for further exploration into the delicate balance between efficacy and safety in topical psoriasis treatments. The study's comprehensive analysis of various topical drugs paves the way for informed decisions in clinical settings, ultimately contributing to better patient outcomes.
