Vectura Group plc

Vectura announces a further US collaboration agreement with a leading international pharmaceutical company for the VR506 asthma therapy

Chippenham, UK - 30 June 2014: Vectura Group plc (LSE: VEC; "Vectura" or the "Company") announces that it has signed a US collaboration, development and license agreement for VR506, Vectura's clinical stage asthma monotherapy delivered using Vectura's proprietary technology. The agreement for VR506 is with Vectura's existing, undisclosed, US partner for VR315 (a combination therapy for asthma/COPD).

Under the terms of this agreement, Vectura's partner will be responsible for the commercialisation and manufacture of the product together with clinical development. Vectura will provide support for the US development of VR506, for which it will receive an initial payment of $4 million and up to $8million upon achievement of pre-determined development milestones. Further development fees may be payable to Vectura if the program progresses beyond a pre-defined milestone. In addition, Vectura will receive a royalty from all VR506 US sales.

Dr. Chris Blackwell, Chief Executive of Vectura:

"This is an important step for the development of VR506 for the potentially lucrative US market and it extends the successful collaboration with our established US partner. This provides additional third party validation of the progress we have made to date and is a major endorsement of the potential value of this product."
