Antisoma and EMD Lexigen announce progress on joint anti-cancer development
programme (ATTACK)
25 November 2003, London, UK and Boston, USA: Antisoma plc (LSE:ASM), the
UK-based biopharmaceutical company specialising in the development of novel
anti-cancer drugs, and EMD Lexigen Research Center, the US-based biotechnology
company, today announce that they have co-developed a novel cancer therapy
based on the application of Lexigen's immunocytokine technology and using
Antisoma's antibody huBC1 and the anti-tumour cytokine IL12. The companies
describe this approach as ATTACK (Anti-tumour Therapy with Targeting Antibodies
and CytoKines).
EMD Lexigen and Antisoma have created an immunocytokine fusion protein
incorporating huBC1 and IL12. This protein has been shown to have anti-tumour
effects in animal models of several different cancers. Work from the companies'
collaboration is being submitted for detailed presentation at forthcoming
scientific congresses.
IL12, when given alone, is known to have potent effects on tumours. Early-phase
safety trials provided evidence of IL12 activity against renal cell carcinomas
and melanomas. However, intravenous administration of IL12 has been associated
with severe and often treatment-limiting side effects. Combining IL12 with a
cancer-targeting antibody is a potential way to harness its anti-tumour
properties while minimising side effects, as a targeted therapy can be given at
lower doses and could act more specifically on tumours. The huBC1 antibody
targets oncofoetal fibronectin, a molecule associated with new tumour blood
vessels. This antibody therefore provides a vehicle with the potential to
deliver IL12 specifically to tumours.
Glyn Edwards, CEO of Antisoma, said, "We are delighted to be collaborating with
a partner of Lexigen's calibre, and are now working with them to identify the
best way to move the promising new ATTACK approach rapidly into clinical
trials."
Stephen Gillies, President of EMD Lexigen and Global Head of Oncology Research
for Merck KGaA, said, "Immunocytokine technology lends itself to many approaches
through different combinations of antibodies and cytokines. We are excited to
work with the novel targeting concept of Antisoma to create an innovative
approach to cancer therapy."
