GSK and Genmab Announce Start of Ofatumumab Phase III Combination Study in Non-Hodgkin's Lymphoma


Summary: GSK and Genmab announce the initiation of a Phase III study of         
ofatumumab in rituximab refractory patients with indolent B-cell non-Hodgkin's  
Lymphoma.                                                                       

London, UK, Copenhagen, Denmark; September 8, 2010 - GlaxoSmithKline (GSK) and  
Genmab A/S (OMX: GEN) announced today the start of a Phase III study in patients
with indolent B-cell non-Hodgkin's lymphoma (B-NHL) who did not respond to or   
progressed during, or within 6 months of a rituximab containing regimen.  Under 
the terms of Genmab's collaboration with GlaxoSmithKline (GSK), Genmab will     
receive a milestone payment of approximately DKK 116 million (approximately USD 
20 million), triggered by the treatment of the first patient in the study.      

About the trial                                                                 
A total of 338 patients in this open label study will be randomized to receive  
either ofatumumab in addition to bendamustine or bendamustine alone. The primary
endpoint of the study is progression free survival. Patients in the bendamustine
monotherapy group will have the opportunity to receive ofatumumab if their      
lymphoma progresses.                                                            

About Indolent B-Cell Non-Hodgkin's Lymphoma                                    
More than one-third of lymphoma patients have indolent B-cell non-Hodgkin's     
lymphoma, which includes follicular lymphoma and other typically slow growing   
lymphomas which initially respond to treatment but relapse with time.(1)        
Indolent B-NHL is defined by expression of the CD20 molecule, which is the      
target of monoclonal antibodies such as rituximab and ofatumumab.(2,3)          

About ofatumumab                                                                
Ofatumumab is a human monoclonal antibody which targets CD20. Ofatumumab is not 
approved in any country for indolent B-cell non-Hodgkin's lymphoma (B-NHL).
