Key Points

  • In patients with mild-to-moderate plaque psoriasis using Sernivo Spray (betamethasone dipropionate 0.05%), almost 75% of plaques on elbows and knees were clear or almost clear of redness and scaling after a period of 29 days.
  • Itching was decreased by 50% at day 4 in some patients, and significant treatment effects with Sernivo started as early as day 8 when compared to a vehicle treatment (spray with no active drug).
  • Sernivo Spray is a mid-potency topical corticosteroid approved for up to 4 weeks of use to treat plaque psoriasis in adults.

In two clinical studies, 538 adult patients who had plaque psoriasis on 10% to 20% of their body surface area received treatment with Sernivo or vehicle. Treatment success with Sernivo was defined as clear or almost clear skin (Investigator Global Assessment) and at least a 2 grade reduction from symptoms present at the start of the study.

  • By day 8, 11% of patients receiving Sernivo had achieved treatment success in one study, compared to 4% with vehicle (p=0.010)
  • By day 15, 20.3% of patients receiving Sernivo had achieved treatment success, compared to 5% with vehicle (p<0.001) - the primary endpoint.
  • By day 29, 38.7% of patients receiving Sernivo had achieved treatment success, compared to 12.6% with vehicle - secondary endpoint (p<0.001)

Bottom Line

  • In patients with mild-to-moderate plaque psoriasis, almost 75% of knee and elbow plaques were clear or almost clear of redness and scaling after a period of 29 days.
  • Itching was decreased by 50% at day 4 in some patients.
  • By day 15, about 20% of patients receiving Sernivo had achieved significant treatment success, compared to 5% with the vehicle.
