Genmab Announces Development Plans for Ofatumumab


Summary: Genmab announces that further development plans for ofatumumab in      
oncology and autoimmune disease will be described today at GlaxoSmithKline's    
Oncology Seminar.                                                               

Copenhagen, Denmark; June 18, 2007 - Genmab A/S (CSE: GEN) announced that       
development plans for ofatumumab (HuMax-CD20(R)) will be described at           
GlaxoSmithKline's (GSK) Oncology Seminar today.  Ofatumumab is currently in late
stage development for chronic lymphocytic leukemia (CLL), follicular            
non-Hodgkin's lymphoma (NHL) and in Phase II for rheumatoid arthritis (RA) and  
is being developed under a worldwide co-development and commercialization       
agreement between Genmab and GSK.                                               

A clear demonstration of the efficacy and safety of ofatumuamb in two late stage
single-arm trials (CLL and follicular NHL), which are not routinely accepted as 
registration studies, could provide the initial regulatory applications. Genmab 
has received a Fast Track designation for the CLL study.  Under these           
circumstances, ofatumumab could potentially enter the market in 2008 first for  
the treatment of refractory CLL and subsequently for rituximab-refractory       
follicular NHL.  We furthermore expect to expand the ofatumumab program into new
indications with the planned initiation of clinical studies in diffuse large    
B-cell lymphoma (DLBCL) by the end of 2007 and randomized Phase III studies in  
CLL and follicular NHL in the first half of 2008.                               
	                                                                               
In the autoimmune disease setting, we expect to initiate  Phase III studies of  
ofatumumab in RA by the end of 2007.  We also plan to expand the development    
program with initiation of a Phase II study in relapsing remitting multiple     
sclerosis (RRMS) in the first quarter of 2008.  There is potential to pursue    
indications in a wide range of autoimmune disease settings.
