New foam delivery method for ketoconazole will provide an additional

treatment option for dermatologists and other physicians

    CORAL GABLES, Fla., July 17 /PRNewswire/ -- Stiefel Laboratories, Inc.
 today announced that the U.S. Food and Drug Administration (FDA) has
 approved its new drug application for Extina(R) (ketoconazole) Foam, 2% for
 the treatment of seborrheic dermatitis. The approval, which the company
 received June 12, clears the way for the product to be sold and marketed in
 the United States.
     Different from other treatments for seborrheic dermatitis, which
 contain ketoconazole 2% in a cream, gel or shampoo vehicle, Extina is
 administered using VersaFoam(R) HF(R) (hydroethanolic formulation)
 technology, a unique, versatile topical drug delivery vehicle that is
 quickly absorbed into the skin. Extina Foam proved to be superior to
 placebo foam in a Phase III clinical trial. Of subjects receiving Extina
 (R) Foam, 56% achieved treatment success based on an Investigator Global
 Assessment compared to 42% of subjects receiving vehicle foam. Stiefel
 Laboratories, the world's largest independent pharmaceutical company
 specializing in dermatology, acquired the proprietary VersaFoam HF
 technology with its December 2006 acquisition of Connetics Corporation.
     "We are very pleased with the robust data obtained in the pivotal Phase
 III clinical trial evaluating the safety and efficacy of Extina," said Jim
 Hartman, Senior Vice President, U.S. Commercial Operations for Stiefel
 Laboratories. "It is exciting that this product, combining the proven
 efficacy of ketoconazole 2% in the patient-preferred foam delivery system
 will soon be available for patients with seborrheic dermatitis. It will
 provide dermatologists and other allied health professionals with an
 additional treatment option for this condition and allow patients to choose
 their preferred drug delivery method.
     "Extina is representative of the robust and innovative product pipeline
 at Stiefel Laboratories," Hartman added.
     Stiefel Laboratories plans to launch the product, which will be
 available only by prescription, later this year.
     Extina(R) (ketoconazole) Foam, 2% is indicated for the topical
 treatment of seborrheic dermatitis in immunocompetent patients 12 years of
 age and older. Extina should be applied to the affected skin areas twice a
 day (morning and evening) for four weeks. Extina is administered via
 VersaFoam HF, which studies show offers consistent skin permeation, drug
 distribution and drug delivery. Additional patient benefits include
 versatility (Extina can be used on hair bearing and non hair-bearing skin),
 it absorbs quickly and it is non-drying with no residue.
