Genmab Amends HuMax-CD4 Pivotal Study in CTCL


Receives Orphan Drug Designation for Nodal T-cell Lymphoma                      

Summary:  Genmab announced today it has amended the ongoing HuMax-CD4 pivotal   
study to treat refractory CTCL and has received an orphan drug designation for  
the treatment of nodal T-cell lymphoma.                                         

Copenhagen, Denmark; October 11, 2007 - Genmab A/S (OMX: GEN) announced today it
has amended the design of the ongoing pivotal study of HuMax-CD4(R)             
(zanolimumab) to treat refractory cutaneous T-cell lymphoma (CTCL) patients.    
The study which previously only included patients with the Mycosis Fungoides    
(MF) form of CTCL has been expanded to include patients with Sézary Syndrome as 
well.  Furthermore, due to higher response rates observed at the 14 mg/kg dose  
level during the first part of the pivotal study, the 8 mg/kg dose level will   
now be discontinued, with all patients to be treated with 14 mg/kg of HuMax-CD4 
once a week for 12 weeks.                                                       

These study amendments have been agreed to by the FDA under the Special Protocol
Assessment agreement already in place.                                          

In addition, HuMax-CD4 has received an orphan drug designation for the treatment
of refractory CTCL in Australia and for the treatment of refractory nodal T-cell
lymphoma in Europe.  HuMax-CD4 previously received Fast Track Status from the   
FDA and orphan drug status in the US and Europe for the treatment of refractory 
CTCL.                                                                           

“We believe expanding the HuMax-CD4 pivotal study to include a broader group of 
CTCL patients will allow us to speed up patient enrollment, test at a more      
effective dose level and potentially offer treatment for Sézary Syndrome        
patients as well as MF patients,” said Lisa N. Drakeman, Ph.D., Chief Executive 
Officer of Genmab.  “The potential of HuMax-CD4 in treating T-cell lymphoma     
patients with unmet medical needs continues to be recognized by the             
international regulatory authorities.”
