Results from 2 identical phase 3 randomized trials indicate that most patients with rosacea can expect a ≥1-grade improvement with treatment with oxymetazoline cream 1.0%, according to data published in the Journal of Drugs in Dermatology.

The investigators sought to assess the reduction in persistent erythema on day 1 of therapy, using data derived from 2 pivotal trials of oxymetazoline cream 1.0% for the treatment of persistent facial erythema of rosacea. Adult patients with moderate to severe persistent facial erythema of rosacea (Clinician Erythema Assessment [CEA] grade ≥3 and Subject Self-Assessment [SSA] grade ≥3) were randomly assigned in a 1:1 ratio to treatment with once-daily topical oxymetazoline cream 1.0% or vehicle.

The primary efficacy outcome of the study was ≥2-grade composite CEA and SSA improvement from baseline on day 29. The current post-hoc analysis of 885 patients (440 from the REVEAL trial 1 and 445 from the REVEAL trial 2 evaluated the proportion of participants who attained ≥1-grade composite and individual CEA and SSA improvement at 1, 3, 6, 9, and 12 hours postdose on day 1 of treatment.

A significantly greater number of patients achieved ≥1-grade composite and individual CEA and SSA improvements with the initial application of oxymetazoline than with vehicle (P <.001) at all postdose time points, starting with hour 1. Safety assessments performed on day 1 were similar in both treatment groups.

Limitations of the study include that it involved only short-term treatment and used post-hoc analyses.

The investigators concluded that the use of oxymetazoline cream 1.0% for the treatment of persistent facial erythema of rosacea is associated with clinical improvements.
