Copenhagen, Denmark; September 23, 2008 - Genmab A/S (OMX: GEN) announced today it has completed recruitment of patients in the pivotal Phase III study of ofatumumab (HuMax-CD20®) in rituximab refractory follicular non-Hodgkin's lymphoma (NHL). Eighty-one patients receiving treatment at the 1000 mg dose level of ofatumumab have been recruited in the study. Data from these patients will be included in the primary efficacy analysis. An additional 31 patients were recruited at a 500 mg dose level prior to amending the study design to include only one dose. Data from these patients will be evaluated for safety and supportive efficacy analysis.

"We have now recruited the last patient into the study and keenly await the results which we hope will show a benefit for follicular NHL patients who need a new treatment option," said Lisa N. Drakeman, Ph.D., Chief Executive Officer of Genmab.

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 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 for sale in any country.

About the trial

Patients in this study will receive one infusion of 300 mg of ofatumumab followed by 7 weekly infusions of 1000 mg of ofatumumab. Disease status will be assessed every 3 months until month 24.

The objective of the study is to determine the efficacy and safety of ofatumumab in rituximab refractory follicular NHL. The primary endpoint of the study is objective response as measured over a 6 month period from start of treatment assessed by an Independent endpoints Review Committee (IRC) according to the standardized criteria for NHL.
