Asterand to Enter Into Exclusive License Agreement with Allergan for Pre-Clinical Compounds Focused on Diseases of the Eye

Asterand to Receive Upfront Payment of $6.25 Million from Allergan in a Pre-Clinical Licensing Deal for Select Compounds That Could Produce Value of up to $56.0 Million in Milestone Payments, Plus Royalties

DETROIT, Sep 08, 2008 (BUSINESS WIRE) -- Asterand plc (LSE: ATD), a leading global provider of human tissue and services to pharmaceutical companies engaged in drug discovery research, announces that it has entered into an exclusive licence agreement with Allergan, Inc., a global, multi-speciality healthcare company, whereby Allergan obtains the rights to further develop and commercialise a series of compounds discovered and developed by Asterand to treat conditions and diseases of the eye, such as glaucoma.

The compounds arise from Asterand's R99 development programme. They are selective, small molecule prostaglandin receptor agonists that have been shown in preclinical studies to be effective in reducing intra-ocular pressure. Allergan plans to further develop a focused list of Lead Compounds and progress these through Clinical Development.

Allergan will pay Asterand an upfront Technology Access Fee of $6.25 million. In addition, Asterand can receive success-based development and sales milestone payments that could total up to $56.0 million, plus royalties.

Martyn Coombs, Chief Executive Officer of Asterand plc said: "Asterand is delighted to have reached this agreement with Allergan. Clearly this is a very significant financial deal for Asterand. We are happy that Allergan has decided to carry our prostaglandin program forward after evaluating it under an exclusive material transfer agreement. Allergan has the expertise, reputation and resources to potentially turn these compounds into effective treatments for diseases of the eye, especially glaucoma.

"Asterand has several other promising drug discovery programmes, including further prostaglandin agonists for immuno-inflammatory diseases (COPD and psoriasis) and pre-term labour, and other interesting compounds targeted for the treatment of bone disease, cancer, and IBS. Asterand will now put increased effort into realising the value of these programmes, including seeking out-licensing opportunities with other pharmaceutical companies. Licensing these programmes allows for their continued development while we focus on our core business, further advancing drug discovery by being the pre-eminent supplier of human tissue and human tissue based services."
