Medicis and Ipsen Announce Submission of Reloxin in Aesthetics to the FDA

Wednesday December 5, 11:00 pm ET

SCOTTSDALE, Ariz. and PARIS, Dec. 5, 2007 (PRIME NEWSWIRE) — Medicis (NYSE:MRX —News) and Ipsen (Euronext: FR0010259150; IPN) today announced the submission of a Biologics License Application (“BLA”) for the botulinum toxin type A, Reloxin(R)(1), in aesthetics to the U.S. Food and Drug Administration’s (“FDA’s”) Division of Dermatology and Dental Products, within the Center for Drug Evaluation and Research. Medicis anticipates a response from FDA in approximately 10 months following FDA’s receipt of the Reloxin(R) submission.

According to the American Society for Aesthetic Plastic Surgery, injections of botulinum toxin type A were the number one non-surgical procedure in 2006, with over 3 million total procedures. Current growth estimates in botulinum toxin type A in dollars are estimated to be in excess of 20 percent over the prior year. This translates into a retail U.S. aesthetic market of approximately $300 million-$400 million(2).

“We are extremely pleased to announce the submission of the BLA for Reloxin(R) with FDA,” said Jonah Shacknai, Chairman and Chief Executive Officer of Medicis. “Our team has dedicated many hours compiling what we believe to be a strong submission for an important product. The primary clinical studies included 83 investigator sites and approximately 3,250 patients. Congratulations to the Medicis team and our talented consultants who worked tirelessly to achieve our submission. Our shareholders owe these persons a tremendous debt of gratitude for their extraordinary efforts. We appreciate the support given to us by our colleagues at Ipsen, and look forward to a continued excellent relationship with them as we prepare for the potential of commercializing Reloxin(R) in the growing, multi-million dollar aesthetic botulinum toxin market in the U.S.”

Jean-Luc Belingard, Chairman and Chief Executive Officer of Ipsen, stated, “The submission of the Reloxin(R) dossier to the FDA by our partner Medicis is an important milestone for Ipsen’s future growth, and we are very pleased that such an important project was carried out in a rigorous and timely manner. Both Ipsen and Medicis are dedicated to bring this product to market, so that Reloxin(R) may be a success in the U.S.”

In March 2006, Ipsen granted Medicis the rights to develop, distribute and commercialize Ipsen’s botulinum toxin product in the United States, Canada and Japan for aesthetic use by physicians. Upon FDA’s acceptance of the Reloxin(R) submission, Medicis will pay Ipsen approximately $25 million in accordance with the agreement between the parties.

Dysport(R) is a neuromuscular blocking toxin which acts to block acetylcholine release, hence reducing muscular spasm was initially developed for the treatment of motor disorders and various forms of muscular spasticity, including cervical dystonia (a chronic condition in which the neck is twisted or deviated), spasticity of the lower limbs (heal) in children with cerebral palsy, blepharospasm (involuntary eye closure) and hemifacial spasm. It was later developed for the treatment of a wide variety of neuromuscular disorders and aesthetic medicine.
