Recruitment Completed in Zalutumumab Head and Neck Cancer Pivotal Study


Summary:  Genmab has completed recruitment of patients in the zalutumumab
pivotal Phase III study in refractory head and neck cancer. 

Copenhagen, Denmark; June 10, 2009 - Genmab A/S (OMX: GEN) announced today it   
has completed enrollment of 273 patients in the zalutumumab pivotal Phase III   
study in refractory head and neck cancer.  Genmab expects to report final       
results from the study by the end of 2009.                                      

About the trial                                                                 
The pivotal study includes patients with squamous cell carcinoma of the head and
neck (SCCHN) who are refractory to or intolerant of standard platinum-based     
chemotherapy.  Patients in the study are randomized into two treatment groups:  
zalutumumab in combination with best supportive care or best supportive care    
alone. Patients treated with zalutumumab in combination with best supportive    
care receive an initial dose of 8mg/kg of zalutumumab, followed by weekly       
infusions of a maintenance dose until disease progression. The maintenance dose 
is adjusted as necessary until the patient develops a dose limiting skin rash,  
up to a maximum dose of 16 mg/kg of zalutumumab. Disease status will be assessed
every 8 weeks by CT scan or MRI according to RECIST criteria until disease      
progression and patients will be followed for survival.                         

The objective of the study is to evaluate the efficacy of zalutumumab in        
combination with best supportive care as compared to best supportive care alone 
in terms of overall survival. The primary endpoint in the study is overall      
survival from randomization until death.
