Arzerra(TM) (ofatumumab) MAA Accepted by EMEA


Summary:  The EMEA has confirmed the Marketing Authorization Application for    
Arzerra is valid and that the review procedure has started.                     

Copenhagen, Denmark; February 26, 2009 - Genmab A/S (OMX: GEN) announced today  
that the European Medicines Agency (EMEA) has confirmed the Marketing           
Authorization Application (MAA) for Arzerra(TM) (ofatumumab) for the treatment  
of chronic lymphocytic leukemia (CLL) is valid and that the review procedure    
started on February 25, 2009.   If approved, ofatumumab would be indicated for  
the treatment of patients with CLL who have previously failed, or are           
inappropriate for, standard therapies.  The MAA was submitted on February 5,    
2009.                                                                           

The acceptance of the MAA will trigger a milestone payment from GlaxoSmithKline 
to Genmab of DKK 58 million (approximately USD 10 million).                     

“We are excited to reach this important milestone so soon after submitting the  
Arzerra(TM) MAA to the European regulatory authorities,” said Lisa N. Drakeman, 
Ph.D., Chief Executive Officer of Genmab.                                       

About ofatumumab                                                                
Ofatumumab is a novel, investigational, fully human monoclonal antibody that    
targets a membrane-proximal (close to the cell surface) small loop epitope (a   
portion of a molecule to which an antibody binds) on the CD20 molecule of       
B-cells.  This epitope is different from the binding sites targeted by other    
CD20 antibodies currently available.  The CD20 molecule is a key target in CLL  
therapy because it is expressed on most B-cells in CLL patients.  In Europe,    
ofatumumab has been granted orphan designation for CLL as it affects            
approximately 3.5 in 10,000 persons in the European Union.                      

Ofatumumab is being developed under a co-development and commercialization      
agreement between Genmab and GlaxoSmithKline. It is not yet approved in any     
country.
