Calcipotriol plus Betamethasone Dipropionate Gel Compared with Tacalcitol Ointment and the Gel Vehicle Alone in Patients with Psoriasis Vulgaris: A Randomized, Controlled Clinical Trial

Objective: To establish the efficacy and safety of once daily treatment of Daivobet®/Dovobet® gel in patients with psoriasis vulgaris, relative to tacalcitol ointment and the gel vehicle alone. Methods: 458 patients with at least moderately severe disease were randomized in 3 treatment arms for an 8-week period. Treatment was investigator blinded, and treatment success was defined as patients with an Investigator’s Global Assessment of ‘clear’ or ‘almost clear’ at week 8. Results: The proportion of patients who were ‘clear or almost clear’ was significantly higher in the 2-compound gel group (39.9%) compared with 17.9% in the tacalcitol group and 5.5% in the gel vehicle group: p < 0.001 in both comparisons. The proportion of patients with at least 1 adverse drug reaction was significantly lower in the 2-compound gel group compared to the other 2 treatment groups. Conclusions: Once-a-day treatment with the 2-compound Daivobet/Dovobet gel is a safe and efficacious therapeutic regimen for individuals with psoriasis on the body.
