RESEARCH TRIANGLE PARK, N.C., Sept. 28, 2012 /PRNewswire/ -- Stiefel, a GSK (NYSE:GSK) company, today announced that the US Food and Drug Administration has approved a supplemental New Drug Application (sNDA) for Sorilux (calcipotriene) Foam, 0.005%. The sNDA expands the indication for Sorilux Foam to include the topical treatment of plaque psoriasis of the scalp in patients aged 18 years and older. It is not known if the product is safe and effective in people under 18 years old.
"Studies have shown that in at least 50 percent of psoriasis cases, the scalp is involved," said Susan Learned, PharmD, MD, PhD, Medicines Development Leader, Dermatology Research and Development, Stiefel. "We believe this additional indication for Sorilux Foam will help meet the needs of both patients and physicians."
The approval of Sorilux Foam for treatment of plaque psoriasis of the scalp was based on a multi-center, randomized, double-blind, vehicle-controlled pivotal Phase 3b study of patients with moderate scalp and body psoriasis. The most common side effects of Sorilux Foam were redness and pain of the treated skin areas. The incidence of these adverse reactions was similar between the body and scalp. It is for use on the skin only. It is not for facial, oral, ophthalmic, or intravaginal use. More information about the clinical trial results can be found in the Full US Prescribing Information at http://www.stiefel.com/content/dam/stiefel/globals/documents/pdf/US_Sorilux_Foam.pdf.
About Plaque PsoriasisPsoriasis is a chronic (life-long) skin disease. It occurs when the immune system "speeds up" the growth cycle of skin cells. A normal skin cell matures and falls off the body in about a month. For people with plaque psoriasis, it can take only three or four days for new skin cells to develop. Instead of falling off, the cells remain on the skin and form thickened patches (lesions or plaques). While plaque psoriasis is a chronic condition, many patients experience times when their symptoms improve or worsen.
