Abstract

Background: Tyrosine kinase 2 (TYK2) is an intracellular kinase that mediates interleukin (IL)-23, IL-12, and interferon (IFN)α/β signaling. Deucravacitinib is a novel, oral, selective inhibitor of TYK2 acting via binding to the TYK2 regulatory domain.1 Phase 2 results showed deucravacitinib was efficacious and well tolerated versus placebo in patients with moderate to severe plaque psoriasis or active psoriatic arthritis.2,3 No herpes zoster infections, opportunistic infections, thromboembolic events, or hematologic or lipid abnormalities characteristic of Janus kinase (JAK) 1−3 inhibitors were reported in the Phase 2 trials.2,3

Objectives: To compare the efficacy and safety of deucravacitinib versus placebo and apremilast in plaque psoriasis.

Methods: This Phase 3, double-blinded, 52-week study (NCT03624127) randomized patients with moderate to severe plaque psoriasis (BSA ≥10%, PASI ≥12, sPGA ≥3) to deucravacitinib 6 mg once daily, placebo, or apremilast 30 mg twice daily (2:1:1). Patients receiving placebo were switched to deucravacitinib at Week 16; apremilast-treated patients not achieving PASI 50 at Week 24 were switched to deucravacitinib. Coprimary endpoints were PASI 75 and sPGA 0/1 response versus placebo at Week 16. Key secondary endpoints included superiority versus apremilast, assessed via multiple measures.

Results: 666 patients were randomized. Demographic and baseline disease characteristics were balanced across groups; mean age was 46.1 years, mean disease duration was 17.3 years, 18.2% of patients had psoriatic arthritis at baseline, and 38.9% had previously used biologic therapy. Mean BSA involvement at baseline was 26.3%, mean PASI was 21.4, and the percentage with severe sPGA (score=4) at baseline was 21.2%. Significantly greater proportions of patients in the deucravacitinib versus placebo and apremilast arms achieved PASI 75 (58.7% vs 12.7% vs 35.1%, respectively; P<0.0001) and sPGA 0/1 (53.6% vs 7.2% vs 32.1%, respectively; P<0.0001) response at Week 16 (Figure 1). Deucravacitinib was also superior to apremilast at Week 24, with 69.0% versus 38.1% of patients achieving PASI 75 and 58.4% versus 31.0% achieving sPGA 0/1 (P<0.0001 for both). In addition, DLQI 0/1 responses at Week 16 were significantly higher with deucravacitinib versus placebo and apremilast, demonstrating improved quality of life (40.7% vs 10.6% vs 28.6%, respectively; Figure 1). During the 16-week, placebo-controlled period, the most common AEs (≥5% in any arm) were nasopharyngitis, upper respiratory tract infection, headache, diarrhea, and nausea (Table 1). Frequencies of SAEs and treatment discontinuations due to AEs were low (Table 1).

Summary of adverse events (AEs) through Week 16

Conclusion: Deucravacitinib demonstrated superiority versus placebo and apremilast across multiple efficacy endpoints in patients with moderate to severe plaque psoriasis, and was generally well tolerated. Overall, the efficacy and safety profile of deucravacitinib was consistent with that observed in the Phase 2 plaque psoriasis and psoriatic arthritis trials.2,3
