New Preclinical Data for Calcipotriol/betamethasone dipropionate(0,005%/0,05%)

MARKHAM, ON--(March 7, 2016) - Data presented in a Late Breaking Science session at the 74th Annual Meeting of the American Academy of Dermatology (AAD) in Washington, D.C. demonstrated that calcipotriol/betamethasone dipropionate 50 micrograms/g / 0,5 mg/g) foam formulation is a stable supersaturated solution of the active ingredients.^{footnote 11} The data presented at AAD showed that no calcipotriol or betamethasone dipropionate crystals were identified in the foam spray following application and for up to 18 hours. 

"We are extremely pleased with the results of this preclinical study, which continue to build our base of evidence to support the efficacy for our product and illustrate why this treatment can make a difference to people living with psoriasis vulgaris," said Gitte Aabo, President and CEO of LEO Pharma. "The data presented at AAD highlight the supersaturation of the product and provide further of evidence of how the product can help patients living with psoriasis vulgaris."

"Supersaturation is important for a topical treatment from a dermatological perspective, as it has been shown to improve how effectively a medicine can penetrate the skin," said Dr. Richard Warren, Senior Lecturer and study author. The safety and efficacy of calcipotriol/betamethasone dipropionate 50 micrograms/g / 0,5 mg/g) foam are still under investigation. Market authorisation in Canada has not yet been obtained.
