Ofatumumab In Subcutaneous Study In Rheumatoid Arthritis Summary: Subcutaneous Administration Of Ofatumumab Investigated In Phase I/II Study

Genmab A/S (OMX: GEN) announced a Phase I/II study to evaluate a
subcutaneous route of administration of ofatumumab (HuMax-CD20(R)) in
rheumatoid arthritis (RA) patients, stable on methotrexate will be initiated
soon. The study, which will consist of two parts and include approximately
70 patients, will be conducted by GlaxoSmithKline.





"The addition of a subcutaneous method of administrating ofatumumab is a
great addition to the ofatumumab development program. We hope this will in
future prove to be an advantage to RA patients, who would potentially be able
to administer ofatumumab on an outpatient basis," said Lisa N. Drakeman,
Ph.D., Chief Executive Officer of Genmab.





Ofatumumab is an investigational drug being developed to treat chronic
lymphocytic leukemia, follicular non-Hodgkin's lymphoma, diffuse large B-cell
lymphoma and rheumatoid arthritis under a co-development and
commercialization agreement between Genmab and GlaxoSmithKline. It is not yet
approved in any country.





About the trial This is a two part study. The objective of Part A of the
study is to characterize the safety and tolerability of ofatumumab when
administered subcutaneously. The primary endpoint is safety and tolerability.
The primary endpoint for Part B is to characterize the
pharmacokinetics/pharmacodynamics of subcutaneous dosing. Patients in both
Part A and Part B are allowed to continue a stable dose methotrexate therapy.





Part A will be a randomized, single-blind, placebo controlled, repeat
dose, parallel group, dose-range finding study of approximately 40 patients.
Administration of ofatumumab for Part A will occur in a hospital based unit
in order to ensure safety.





Part B will be a blinded, randomized, placebo controlled study. On the
basis of findings in Part A of the study selected doses will be taken forward
for administration in Part B. Dosing for Part B is planned to be conducted on
an outpatient basis.





About RA RA is a chronic systemic inflammatory disease which affects
0.8-1.0% of all populations. RA patients suffer from damage and disruption of
joints beginning early in the course of their disease. For most patients bone
erosion progress will lead to joint deformities. Unless the inflammatory
processes are halted or controlled, the disease will lead to disability,
co-morbidities, and in many cases also premature death.
