LONDON--(Marketwire - June 9, 2009) -

SKYEPHARMA PLC - FlutiformTM U.S. Filing Update

SkyePharma PLC (LSE: SKP) today announces
that the US Food and Drug Administration (FDA) has issued a
communication in respect of the New Drug Application (NDA) for its lead
development product, FlutiformTM (fluticasone propionate/formoterol
fumarate), an investigational treatment for persistent asthma in
patients 12 years of age and older.

The communication, known as a 74-day letter, confirms, as previously
announced, that the NDA is sufficiently complete to permit a
substantive review and, in line with standard review practice, the FDA
has given preliminary notice of some potential review issues.  The FDA
states that its filing review is only a preliminary evaluation of the
application and is not indicative of deficiencies that may be
identified during its review and that issues may be added, deleted,
expanded upon, or modified as it reviews the application.

Further clarification is required of some of these potential review
issues and steps are being taken to seek discussions with the FDA with
a view to agreeing how they may be addressed.  Although the
requirements cannot be precisely assessed prior to discussion with the
FDA, based on a preliminary assessment, it appears likely that some
additional clinical work may be required to provide more data on

As previously announced, the regulatory review timeline for asthma
treatments is typically longer than the standard 10-month Prescription
Drug User Fee Act timeline.  Should additional clinical work be
required this is likely to impact on the timeline for the review and
any potential approval.

The potential review issues are not expected to have an impact upon the
development of FlutiformTM for Europe or Japan.
