Genmab and Pepscan to Identify Human Antibodies Against Intractable Targets


Summary:  Genmab and Pepscan announced the start of a research collaboration    
aimed at identifying fully human monoclonal antibodies against intractable      
disease targets.                                                                

Copenhagen, Denmark and Lelystad, NL; March 3, 2008 - Genmab A/S (OMX: GEN) and 
Pepscan today announced the start of a research collaboration aimed at          
identifying fully human monoclonal antibodies against intractable disease       
targets.  Intractable targets include those that are difficult to address using 
commonly available technologies but are highly desirable for targeting with     
monoclonal antibodies.  These difficulties can for example be due to the fact   
that target proteins are buried to a large extent very close to the cell surface
or in the cell membrane or due to poor immunogenicity of the protein or         
desirable epitopes.                                                             

In the collaboration, Pepscan will use its proprietary CLIPS™ technology to     
identify functional mimics of the essential parts of such intractable targets.  
These mimics will be used by Genmab to create and select unique therapeutic     
antibodies using its fully human monoclonal antibody technology.                

“As part of our efforts to expand Genmab's pipeline, we continually evaluate    
disease targets which may effectively be addressed with monoclonal antibodies,” 
said Lisa N. Drakeman Ph.D., Chief Executive Officer of Genmab.  “This research 
collaboration with Pepscan will allow us to include in our evaluations a wider  
variety of disease targets that may not be easily addressed using standard      
treatments.”                                                                    

Joost van Bree, CEO of Pepscan Therapeutics comments: “monoclonal antibodies    
against intractable targets are a significant unmet need. The combination of    
Pepscan CLIPS™ protein mimicry platform with Genmab's ability to generate fully 
human monoclonals will enable the partners to develop innovative products for   
poorly served indications.”

About Pepscan Therapeutics                                                      
Pepscan Therapeutics is a product focused immunotherapy company based in the    
Netherlands. It has developed a pipeline of therapeutic vaccine and antibody    
programs of which the most advanced is in Phase II clinical testing. Pepscan's  
proprietary CLIPS™ technology has been proven to yield functional antibodies    
reactive with a range of complex proteins, including GPCRs.                     

About CLIPS™ Technology                                                         

Chemically Linked Immunogenic Peptides on Scaffolds (CLIPS™) is a technology to 
present one or more peptides in a structurally constrained configuration. These 
molecules behave as functional mimics of complex protein domains that serve as  
superior immunogens in the induction and selection of antibodies against disease
relevant protein targets. This is especially valuable in the case of proteins   
that are inaccessible as recombinant proteins (e.g. GPCRs, ion channels,        
patented proteins).
