Connetics Launches Verdeso Foam for the Treatment of Mild-to-Moderate Atopic Dermatitis in Children and Adults

Connetics Corporation (NASDAQ: CNCT), a specialty pharmaceutical company that develops and commercializes dermatology products, today announced the nationwide U.S. commercial launch of Verdeso™ (desonide) Foam, 0.05%, for the treatment of mild-to-moderate atopic dermatitis in adults and children as young as three months of age. Verdeso, a low-potency topical steroid, is the first commercial product formulated in Connetics’ proprietary VersaFoam-EF™ emulsion formulation foam vehicle, and is the first Connetics product to include a pediatric indication. Verdeso is available in 50g and 100g trade unit sizes.

“Our trained and highly motivated sales force has introduced Verdeso to dermatologists and pediatricians,” said Tom Carey, Senior Vice President, Commercial Operations for Connetics. “The launch is supported with patient education materials, product samples, physician speaker programs and an innovative marketing campaign designed to emphasize the value that Verdeso brings to physicians and their patients. In addition to the considerable efforts of our sales organization, our marketing team has designed a creative journal advertising campaign, direct mail programs and an interactive web site, www.Verdeso.com, designed to educate healthcare professionals and their patients.”

Greg Vontz, President and Chief Operating Officer for Connetics, said, “Verdeso provides a great opportunity for our sales force to leverage the reputation of our leading Luxíq® and OLUX® brands, both of which are formulated in VersaFoam®, by demonstrating the advantages of our new VersaFoam-EF technology to a large market. The VersaFoam-EF vehicle is designed to be non-stinging and contains ingredients with moisturizing properties that we believe will lead to increased patient satisfaction and compliance, and accelerated adoption of Verdeso. We also believe Verdeso will be particularly appealing to the pediatric market.”

The launch of Verdeso allows Connetics to offer a complete range of potencies in topical steroids, including mid-potency Luxíq and super high-potency OLUX, and to address the full $1.1 billion topical steroid market. Approximately 7.7 million prescriptions are written annually in the U.S. by dermatologists for low-potency steroid products, and desonide is the leading topical corticosteroid in this market.

About Atopic Dermatitis

Atopic dermatitis (AD), commonly referred to as eczema, is a chronic skin disorder characterized by scaly and itchy rashes. People with atopic dermatitis often have a family history of allergic conditions such as asthma, hay fever or eczema. AD is most common in infants, and at least half of those cases clear by age three. In adults AD generally is a chronic, or recurring, condition. In AD a hypersensitivity reaction (similar to an allergy) occurs in the skin, causing chronic inflammation. The inflammation causes the skin to become itchy and scaly. Chronic irritation and scratching can cause the skin to thicken and develop a leathery texture. Exposure to environmental irritants can worsen symptoms, as can dryness of the skin, exposure to water, temperature changes and stress. Symptoms of AD can include intense itching, blisters with oozing and crusting, skin redness or inflammation around the blisters, and rash.
