Flutiform NDA Accepted for Review

Skyepharma plc: Flutiform NDA Accepted for Review

LONDON, 22 May 2009 - SkyePharma PLC today announces that the New Drug Application (NDA) for its lead development product, Flutiform (fluticasone propionate/formoterol fumarate), an investigational treatment for persistent asthma in patients 12 years of age and older, has been accepted for review by the US Food and Drug Administration (FDA).

If approved, Flutiform will be the first ever fixed-dose medication combining fluticasone, an inhaled corticosteroid (ICS), and formoterol, a long-acting beta agonist (LABA), in the US. Using an environmentally-friendly aerosol propellant, hydrofluoroalkane (HFA), in a metered-dose inhaler, Flutiform is aimed at the combination ICS/LABA inhaler market, which is forecast to generate approximately US$10 billion worldwide by 2010.

As previously announced, the NDA for Flutiform was submitted to the FDA in Q1 2009. The acceptance of the filing means the FDA has determined that the NDA is sufficiently complete to permit a substantive review. The regulatory review timeline for asthma treatments is typically longer than the standard 10-month Prescription Drug User Fee Act (PDUFA) timeline.

Following the acceptance of the NDA for review, an amount of US$2 million is due to SkyePharma from which the filing fee of US$1.2 million will be deducted.

Dr. Ken Cunningham, CEO of SkyePharma, said "We are pleased that the FDA has accepted the Flutiform NDA for review. This is a further step in the development of Flutiform. We believe that, if approved, Flutiform will provide physicians and asthma patients with an important additional treatment option to help manage this serious, chronic condition."
