Genmab Reaches Fifth Milestone in Ofatumumab Collaboration


Summary:  Genmab will receive a milestone payment of approximately DKK 232.7
million from GSK for achievement of positive results in the Phase III CLL
study. 

Copenhagen, Denmark; August 21, 2008 - Genmab A/S (OMX: GEN) announced today it
has reached the fifth milestone for ofatumumab (HuMax-CD20(R)) under the terms
of its collaboration with GlaxoSmithKline (GSK).  A milestone payment of
approximately DKK 232.7 million (approximately USD 48.5 million) was triggered
by the achievement of positive results in the Phase III study of ofatumumab in
refractory chronic lymphocytic leukemia (CLL).  Genmab has received an
approximate total of DKK 552 million (approximately USD 110 million) in
milestone payments under the collaboration so far. 

“While achievement of this milestone represents an important potential turning
point for Genmab,” said Lisa N. Drakeman, Ph.D., Chief Executive Officer of
Genmab, “it is even more important for CLL patients who are waiting for new
treatments to combat their difficult to treat disease.” 

Ofatumumab is an investigational new generation fully human monoclonal antibody
that targets a distinct, membrane proximal, small loop epitope (specific
antibody binding site) of the CD20 molecule on B cells. Ofatumumab is being
developed to treat CLL, follicular non-Hodgkin's lymphoma, diffuse large B-cell
lymphoma, rheumatoid arthritis and relapsing remitting Multiple Sclerosis under
a co-development and commercialization agreement between Genmab and
GlaxoSmithKline. It is not yet approved in any country.
