The positive recommendation has been issued during this week's meeting of the CHMP, the scientific committee that evaluates medicinal products for human use within the EU since the accession of the 10 new member states on May 1, 2004. Raptiva received the CHMP positive opinion for the 'Treatment of adult patients with moderate to severe chronic plaque psoriasis who have failed to respond to, or who have a contraindication to, or are intolerant to other systemic therapies including cyclosporine, methotrexate and PUVA'. Serono expects the European Commission's Marketing Authorisation during the third quarter of this year and plans to initiate the launch of the product in EU countries shortly thereafter. "The CHMP's positive opinion is very good news for people with psoriasis as Raptiva can offer an effective therapy to those whose needs are not met by current treatments," said Ernesto Bertarelli, Chief Executive Officer of Serono. "This indication is entirely consistent with the results of our CLEAR study, which showed that Raptiva is safe and efficacious in this significant group of high-needs patients." Serono received authorisation for Raptiva in Switzerland in March and in Argentina last month and is awaiting the outcomes of marketing applications in a number of other territories for which it is responsible. Raptiva has also been available since November 2003 in the U.S., where it is marketed by Genentech for the treatment of moderate to severe chronic plaque psoriasis in adults aged 18 or older who are candidates for systemic therapy or phototherapy. 1/3 Serono will hold a conference call for investors on June 25, 2004 starting at 3:00 pm CET during which its management will discuss the CHMP opinion on Raptiva. Details of the conference call are available at the end of this press release. Additionally JPMorgan will host an Investor Day on July 7, 2004 in Geneva starting at 2:00 pm CET during which Serono management will provide an update for investors on Raptiva. This JPMorgan event will also be relayed by live audio webcast, which will be accessed through the following link: http://events.genesysrichmedia.com/JPMORGAN/2004/07/07/. *** ABOUT RAPTIVA(R) Raptiva(R) is a humanized therapeutic antibody designed to selectively and reversibly block the activation, reactivation and trafficking of T-cells that lead to the development of psoriasis symptoms. Raptiva is designed to be administered once weekly via subcutaneous injection and can be self-administered by patients at home. Serono has the rights to develop and market Raptiva worldwide outside of the United States and Japan. On March 16, 2004, Serono announced approval for Raptiva in Switzerland for adult patients with moderate-to-severe plaque psoriasis. Serono announced in February 2003 that it had submitted a Marketing Authorization Application (MAA) to the European Agency for the Evaluation of Medicinal Products (EMEA) for European Union Approval of RAPTIVA in psoriasis. Development and marketing rights in the United States remain with Genentech Inc. (NYSE:DNA) and its U.S. partner XOMA (Nasdaq: XOMA). More than 3,500 patients in the U.S. and Europe have been included in Raptiva trials to date, creating the largest existing database of patients taking part in studies with a biological therapy for psoriasis. ABOUT PSORIASIS Psoriasis is a T-cell mediated disease which occurs when skin cells grow abnormally, resulting in thick, red, scaly, inflamed patches. Plaque psoriasis, the most common form of the disease is characterized by inflamed patches of skin ("lesions") topped with silvery white scales. Psoriasis can be limited to a few spots or involve extensive areas of the body, appearing most commonly on the scalp, knees, elbows and trunk. Although it is highly visible, psoriasis is not a contagious disease. While there are a number of medications that may help control the symptoms of psoriasis, there currently is no known cure.
