Out-Licensing Enhances EUSA's Strategic Focus on Late-Stage and Marketed

Products

DOYLESTOWN, Pennsylvania and OXFORD, England, February 18 /PRNewswire/ -- EUSA Pharma Inc ('EUSA'), a transatlantic specialty pharmaceutical company focused on oncology, pain control and critical care, today announced that it has out-licensed the exclusive world-wide rights to its preclinical-stage human anti-interleukin-6 antibody to GlaxoSmithKline (GSK) for a consideration of up to $44 million, comprising an upfront fee and development milestones, plus royalties on future sales. As part of the agreement EUSA will pay approximately 50% of the overall consideration to its development partner for the antibody, Vaccinex Inc. GSK will fund and conduct all future development, production and commercialization of the product.

Interleukin-6 is a pro-inflammatory cytokine and B-cell growth factor and acts as a resistance factor to standard chemotherapy. EUSA's product, OP-R003, is the first fully human anti-interleukin-6 antibody, with target indications in oncology and inflammatory diseases. OP-R003 is derived from a first generation murine antibody, elsilimomab, which has achieved promising clinical results as a lymphoma therapy. As a fully human antibody, OP-R003 has the potential to offer improved tolerability and a superior safety profile.

EUSA acquired OP-R003 as part of the company's 2007 acquisition of OPi SA. OPi had previously entered a collaboration with Vaccinex, a specialist antibody discovery and development company, to optimize and develop OP-R003 as a therapy for rheumatoid arthritis and lymphoma.

"The out-licensing of this early-stage antibody is another strategic milestone for EUSA, as we continue to focus our business on marketed and late-stage products in the oncology, pain control and critical care areas," said Bryan Morton, Chief Executive of EUSA Pharma.
