CAMBRIDGE ANTIBODY TECHNOLOGY AND HUMAN GENOME SCIENCES COMMIT TO EXCLUSIVE
DEVELOPMENT OF ANTIBODY TO TRAIL RECEPTOR-2
TRAIL Receptor-2 human monoclonal antibody to be developed for cancer treatment
Melbourn, UK and Rockville, Maryland, USA... Cambridge Antibody Technology (LSE:
CAT; NASDAQ: CATG) and Human Genome Sciences Inc. (NASDAQ: HGSI) today announce
that HGSI has exercised an option to enter into an exclusive development
partnership on a human monoclonal antibody to TRAIL Receptor-2 (TRAIL-R2 mAb).
TRAIL-R2 mAb is an agonistic antibody that specifically recognises the TRAIL
Receptor-2 protein, found on the surface of a number of cancer cell types.
In pre-clinical studies, TRAIL-R2 mAb has demonstrated the ability to reduce or
prevent the growth of certain tumours in animal models.
HGSI discovered TRAIL Receptor-2. TRAIL Receptor-2 is a member of the tumour
necrosis factor (TNF) family of receptors, and is called a "death receptor"
because of its ability to cause tumour cell death when triggered by the natural
ligand TRAIL (tumour necrosis factor-related apoptosis-inducing ligand). TRAIL
Receptor-2 has been shown to be expressed on a number of solid tumours,
including lung, prostate and breast tumours, and tumours of hematopoietic
origin. It has been demonstrated that cell lines derived from such tumours are
sensitive to killing by apoptosis induced by binding to TRAIL and TRAIL-R2 mAb.
Unlike the natural TRAIL ligand, TRAIL-R2 mAb does not bind to the surface
proteins DcR1 and DcR2 or the soluble receptor osteoprotegerin. TRAIL binds to
these proteins, but such binding does not trigger cell death.
HGSI and CAT announced an antibody product development alliance in early 2000.
The agreement provides HGSI with rights to use CAT's antibody technology to
develop and sell human antibodies for therapeutic and diagnostic purposes. In
return, CAT is entitled to receive licence fees, clinical development milestones
and royalties on product sales from HGSI.
TRAIL-R2 mAb is the third HSGI antibody drug candidate to emerge from the
collaboration between HGSI and CAT. The others are TRAIL-R1 mAb, a human
monoclonal antibody to TRAIL Receptor-1 for use in treating certain cancers, and
LymphoStat-BTM, a human monoclonal antibody to BLySTM (B-lymphocyte stimulator)
for use in treating lupus and rheumatoid arthritis. HGSI holds the commercial
rights to all three drugs. These drugs will be produced in the HGSI
manufacturing facility located in Rockville, Maryland, USA.
Peter Chambre, CAT's CEO, said, "We are delighted that our collaboration with
Human Genome Sciences continues to progress rapidly. We are proud to follow the
achievements on the TRAIL-R1 human antibody with the successful isolation of the
TRAIL-R2 human antibody. Significantly, TRAIL-R2 mAb, like TRAIL-R1 mAb, is
directed to a cell-surface receptor protein. We look forward to further success
in our collaboration with HGSI."
William A. Haseltine PhD, Chairman and Chief Executive Officer of Human Genome
Sciences, said, "Our collaboration with Cambridge Antibody Technology is clearly
productive. In November 2001, we announced clearance by the US Food and Drug
Administration to initiate human testing of LymphoStat-B for use in treating
lupus and rheumatoid arthritis. At the end of April 2002, we announced clearance
to initiate human testing of TRAIL-R1 mAb for use in treating solid tumours and
tumours of hematopoietic origin. TRAIL-R1 mAb is specific to TRAIL Receptor-1,
while TRAIL-R2 mAb is specific to TRAIL Receptor-2. The activity of both
molecules is novel. Both are designed to mimic the activity of the natural TRAIL
ligand, which stimulates these receptors to cause cancer cell death through
apoptosis. Both also are designed to have the advantage of a longer half-life
and the potential for greater efficacy than TRAIL itself. We look forward to
completing the pre-clinical development of TRAIL-R2 mAb, and to entering this
promising anti-tumour drug candidate into clinical trials."
