- Summary: Genmab has Reached the Sixth Milestone in its Ofatumumab Collaboration With GSK

Genmab A/S (OMX: GEN) announced today it has reached the sixth milestone for ofatumumab (HuMax-CD20(R)) under the terms of its collaboration with GlaxoSmithKline (GSK). A milestone payment of approximately DKK 29 million (approximately USD 5.6 million) was triggered by the first patient receiving treatment in the ofatumumab Phase I study in relapsed/refractory follicular non-Hodgkin's lymphoma and chronic lymphocytic leukemia in Japan.

Ofatumumab is an investigational, new generation, human monoclonal antibody that targets a distinct membrane proximal, small loop epitope (specific binding site) of the CD20 molecule on the surface of B-cells. Ofatumumab is being developed to treat chronic lymphocytic leukemia, 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 for sale in any country.
