US regulatory submission of the first aerosol foam for psoriasis

LEO Pharma announced it has submitted a New Drug Application to the US Food and Drug Administration (FDA) for calcipotriene/ aerosol foam 0,005%/0,064% for the treatment of .

The novel aerosol foam formulation of the fixed combination calcipotriene/betamethasone dipropionate has been developed with the aim of improving treatment for patients with vulgaris[1,2] – the most common clinical form of psoriasis.[3]

The regulatory submission in the US is based on studies of patients with psoriasis vulgaris. These include the Phase 3a PSO-FAST study which evaluated efficacy, safety, itch relief and itch-related sleep loss across a four week period,[4] and the Phase 2 MUSE safety study.[5]

Kim Kjøller, Senior Vice President, Global Development, commented:

“Psoriasis is a chronic, debilitating disease. Patients with inadequately managed psoriasis can experience substantial burden of illness, with similar reductions in quality of life to those experienced by patients with diabetes or cancer.[5]

With the regulatory submission announced today, we are taking a step further in our mission towards reducing this burden by making calcipotriene/betamethasone dipropionate aerosol foam available for people living with psoriasis.”

Regulatory filings in Europe and other countries are planned during the course of 2015 and 2016.

With this latest submission LEO Pharma reinforces a strong commitment to dermatology.

About Psoriasis

Psoriasis is a chronic, inflammatory disease, which is frequently accompanied by multiple physical and/or psychological comorbidities, such as metabolic syndrome and psoriatic arthritis.[5]

Psoriasis is estimated to affect about 2-4% of the population in western countries.[6] 80% of patients are affected by psoriasis vulgaris – the most common clinical form of psoriasis.[3]

Topical treatments are first-line therapies for the majority of patients since approximately 80% of the patients have mild or moderate psoriasis.[3]
