Reloxin BLA Submitted to FDA

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

PARIS & SCOTTSDALE, Ari.--(BUSINESS WIRE)--March 17, 2008 - Medicis and Ipsen today announced that Ipsen has submitted a Biologics License Application ("BLA") for the botulinum toxin type A, Reloxin(1), in aesthetic indications (glabellar lines) to the U.S. Food and Drug Administration's ("FDA") Division of Dermatology and Dental Products, within the Center for Drug Evaluation and Research. This BLA submission by Ipsen is intended to address the concerns cited by the FDA when it declined to file the Reloxin BLA in January 2008, which Medicis had submitted in late 2007. Standard response timeframe from the FDA is expected approximately 10 months following receipt of the Reloxin submission. Subject to approval of the BLA by the FDA, Medicis intends to commercialize Reloxin in the U.S. in accordance with the long-standing arrangement between Medicis and Ipsen. Changes from the original BLA submission relate primarily to sponsorship and ownership of the filing. The substantive elements of the original submission remain unchanged.

Jean-Luc Belingard, Chairman and Chief Executive Officer of Ipsen, said: "We are pleased to have responded to the administrative issues raised by the FDA in coordination with Medicis in a timely and efficient manner. Together with Medicis, we look forward to working diligently with the FDA to obtain a successful marketing approval. Given Ipsen's botulinum toxin positive track record on a global basis, we look forward to entering the North American market following FDA approval of Reloxin."

"We are pleased to announce this submission of the BLA for Reloxin in aesthetics with FDA," said Jonah Shacknai, Chairman and Chief Executive Officer of Medicis. "Both the Ipsen and Medicis teams have worked diligently with FDA to determine the best solution for submitting Reloxin in aesthetics. We thank everyone involved, and extend our appreciation to FDA for its willingness to work with us on a resolution in a timely fashion. We continue to believe the Reloxin BLA is strong, and anticipate entering in the growing, multi-million dollar aesthetic botulinum toxin market in the U.S. upon FDA approval."

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 submission, Medicis will pay Ipsen approximately $25 million in accordance with the agreement between the parties.

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)

About Ipsen's Botulinum Toxin Type A

As of October 2007, Ipsen's botulinum toxin type A is approved for aesthetic indications in 21 countries: Argentina, Australia, Belarus, Brazil, Columbia, Ecuador, Egypt, Germany, Honduras, Israel, Kazakhstan, Mexico, Moldova, New Zealand, Philippines, Slovak Republic, Ukraine, Uruguay, Venezuela, Vietnam, and Russia (in Russia, it is the first botulinum toxin type A approved in this field). Ipsen is also pursuing regulatory approval for medical indications for the product in certain additional key international markets.

Dysport is a neuromuscular blocking toxin which acts to block acetylcholine release, hence reducing muscular spasm and 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. Dysport was originally launched in the United Kingdom in 1991 and has marketing authorisations in over 70 countries (at 31 December 2006). Ipsen has just recently filed a BLA for Dysport in cervical dystonia to the FDA.
