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)

What are the most common side effects with Sernivo?

Sernivo Spray was well-tolerated in clinical studies over a 28-day period and few patients experienced side effects. Side effects occurred in 6% of patients or less.

The most common side effects (>1%) that were reported during treatment with Sernivo were:

  • itching
  • burning
  • stinging
  • pain
  • skin thinning

Sernivo Spray may pass through your skin and cause side effects with your adrenal gland. Your doctor may do blood tests to check for adrenal gland problems. These side effects are rare and may occur more frequently if you use Sernivo Spray at larger doses or for a longer period of time than recommended. Follow your doctor's instructions exactly.
