SkyePharma announces commencement of

 Phase III trials for Flutiform™ in Japan

LONDON, UK, 22 November 2010 - SkyePharma PLC (LSE: SKP) today announces that enrolment for two Phase III studies to assess efficacy and safety of Flutiform™ has commenced in Japan.

The two Phase III trials will provide clinical data to support the regulatory process in Japan. One of the trials is a multicentre, comparative study designed to confirm the efficacy and safety of Flutiform™ compared with monotherapy, and the second is a long-term study to confirm the safety and efficacy of Flutiform™.

Under the agreement with Kyorin for Japan, development and approval milestones worth several million pounds are payable to SkyePharma and there is a high mid single digit percentage royalty on net sales. The development costs associated with obtaining approval for the Japanese market will largely be met by Kyorin, which is responsible for clinical studies and regulatory submissions.

The Group continues to make preparations for a potential launch of Flutiform™ in Europe in 2011. The Marketing Authorisation Application was submitted to the MHRA in March 2010. Mundipharma has the rights to market the product in Europe.

Dr Axel Müller, Chief Executive Officer, said: "We are pleased to report continued progress, ahead of schedule, with the development programme for Flutiform™ in Japan. We look forward to working with our partner, Kyorin, as we move a step closer towards commercialising Flutiform™ in this important and growing market."
