Ipsen and Medicis Announce Acceptance of Reloxin BLA in Aesthetics by FDA

SCOTTSDALE, Ariz. and PARIS, May 19, 2008 -- Ipsen and Medicis today announced that the Food and Drug Administration (``FDA'') has accepted the filing of Ipsen's Biologics License Application (``BLA'') for Reloxin(R), its botulinum toxin type A in aesthetic use (glabellar lines) in the United States. This acceptance signifies the start of the review process of the dossier.
In accordance with the agreement between the two parties, Medicis will pay Ipsen approximately $25 million in connection with the announcement made today. Subject to approval of the BLA by the FDA, Medicis will pay to Ipsen a further $75 million and will commercialize Reloxin(R) in the U.S.

About Ipsen's Botulinum Toxin Type A

As of April 2008, Ipsen's botulinum toxin type A, developed in the field of aesthetic medicine in the U.S., Canada and Japan under the trademark Reloxin(R), is approved for aesthetic indications in 23 countries: Argentina, Australia, Belarus, Brazil, Columbia, Ecuador, Egypt, El Salvador, Germany, Honduras, Israel, Kazakhstan, Mexico, Moldova, New Zealand, Philippines, Slovak Republic, South Korea, 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(R) 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(R) was originally launched in the United Kingdom in 1991 and has marketing authorisations in over 70 countries (at 31 March 2008). Ipsen has also recently filed a BLA for Dysport(R) in cervical dystonia to the FDA.

Ipsen Forward-Looking Statements

The forward-looking statements and targets contained herein are based on Ipsen's management's current views and assumptions. Such statements involve known and unknown risks and uncertainties that may cause actual results, performance or events to differ materially from those anticipated herein. The Group does not commit nor gives any guarantee that it will meet the targets mentioned above. Moreover, the Research and Development process involves several stages at each of which there is a substantial risk that the Group will fail to achieve its objectives and be forced to abandon its efforts in respect of a product in which it has invested significant sums. Therefore, the Group cannot be certain that favorable results obtained during pre-clinical trials will be confirmed subsequently during clinical trials, or that the results of clinical trials will be sufficient to demonstrate the safe and effective nature of the product concerned. Ipsen expressly disclaims any obligation or undertaking to update or revise any forward looking statements, targets or estimates contained in this press release to reflect any change in events, conditions, assumptions or circumstances on which any such statements are based, unless so required by applicable law. The Group also faces the risk of product liability claims relating to their safety, notably for its neuromuscular disorders products (marketed under the brand name Dysport(R) notably) that may cause, or may appear to cause, serious adverse side effects or potentially dangerous drug interactions if misused or improperly prescribed. The Group is subject to adverse event reporting pharmacoviligance obligations that require to report to regulatory authorities if the Group's products are associated with serious adverse events, including patient death or serious injury. These adverse events, among others, could result in additional regulatory constraints, such as additional requests from the regulatory authorities during reviews of applications filed for marketing approvals in various countries which could delay the launch time of the given products in new markets, the performance of costly post-approval clinical studies or revisions to the approved labeling limiting the indications or patient population for the Group's products or could even lead to the withdrawal of a product from the market. Such events could harm the sales of the product and therefore have a material negative impact on the Group's financial situation. Furthermore, any adverse publicity associated with such an event could cause consumers to seek alternatives to the Group's products, which may cause sales to decline, even if the Ipsen product at stake is ultimately determined not to have been the cause of the reported serious adverse event. Ipsen's business is subject to the risk factors outlined in its information documents filed with the French Autorite des Marches Financiers.
