The labeling for Otezla (apremilast; Amgen) has been updated to include safety and efficacy information related to the treatment of patients with moderate to severe plaque psoriasis of the scalp.

The STYLE trial was a double-blind, placebo-controlled study that included 303 patients with moderate to severe plaque psoriasis of the scalp who had a Scalp Physician Global Assessment (ScPGA) score of ≥3, Scalp Surface Area (SSA) involvement of ≥20%, and an inadequate response or intolerance to at least 1 topical therapy for plaque psoriasis of the scalp. Enrolled patients also had moderate to severe plaque psoriasis (body surface area [BSA] involvement of ≥10%, static Physician Global Assessment [sPGA] of ≥3 [moderate or severe disease], and Psoriasis Area and Severity Index [PASI] score ≥12).

Patient demographics included the following:

  • Mean age: 46.9 years; 61.7% were men; 75.6% were white
  • 76.9% had moderate scalp psoriasis (ScPGA of 3)
  • 23.1% had severe scalp psoriasis (ScPGA of 4)
  • 71.6% were biologic naive
  • 58.8% had failed 1-2 topical therapies
  • Mean Whole Body Itch Numeric Rating Scale (NRS) score: 7.2 (range 0 [no itch] to 10 [worst imaginable itch])
  • Mean Scalp Itch NRS: 6.7 (range 0 [no itch] to 10 [worst imaginable itch])
  • Mean SSA involvement: 60.6%
  • Mean BSA involvement: 19.8%

Patients were randomized to receive Otezla 30mg twice daily (n=201) or placebo (n=102) for 16 weeks. The primary end point of the study was the proportion of patients who achieved ScPGA response at Week 16 (defined as ScPGA score of clear [0] or almost clear [1] with at least a 2-point reduction from baseline at Week 16). Secondary end points included the proportion of patients with Whole Body Itch NRS response (defined as ≥4-point reduction from baseline) and the proportion of patients with a Scalp Itch NRS response (defined as ≥4-point reduction from baseline).

Results showed that a larger proportion of patients treated with Otezla had ScPGA response compared with placebo (43.3% vs 13.7%; treatment difference: 29.6%; 95% CI, 19.5-39.7). In addition, a greater percentage of Otezla-treated patients had Whole Body Itch NRS response and Scalp Itch NRS response (45.5% and 47.1%, respectively) vs placebo-treated patients (22.5% and 21.1%, respectively).
