Two phase 3 trials—POETYK PSO-1 and POETYK PSO-2 (N=1686)—found deucravacitinib to be notably more effective than both placebo and apremilast in treating psoriasis.19 Among participants receiving deucravacitinib 6 mg daily, 58.7% and 53.6% in the 2 respective trials achieved psoriasis area and severity index 75 response vs 12.7% and 9.4% receiving placebo and 35.1% and 40.2% receiving apremilast. Overall, the treatment was well tolerated, with a low rate of discontinuation of deucravacitinib due to AEs (2.4% of patients on deucravacitinib compared to 3.8% on placebo and 5.2% on apremilast). The most frequently observed AEs with deucravacitinib were nasopharyngitis and upper respiratory tract infection. The full results of these trials are expected to be published soon.19,20
Final Thoughts
Overall, JAK inhibitors are a novel class of therapeutics that may have further success in the treatment of other dermatologic conditions that negatively affect patients’ quality of life and productivity. We should look forward to additional successful trials with these promising medications.
