GSK and Genmab Receive Accelerated Approval for Arzerra


Summary:  GSK and Genmab have received approval of Arzerra (ofatumumab) from the
FDA for CLL that is refractory to fludarabine and alemtuzumab.                  

Philadelphia, PA and Copenhagen, Denmark; October 26, 2009 - Today,             
GlaxoSmithKline (GSK) and Genmab A/S (OMX: GEN) announced the accelerated       
approval of ArzerraTM (ofatumumab) from the US Food and Drug Administration for 
use in patients with chronic lymphocytic leukemia (CLL) that is refractory to   
fludarabine and alemtuzumab.                                                    

“The approval of Arzerra brings an important new treatment option to patients   
with refractory CLL,” said Lisa N. Drakeman, Ph.D., Chief Executive Officer of  
Genmab. “This approval also marks a key milestone for Genmab as it is our first 
antibody to reach the market.  All of us involved in the development of Arzerra 
are pleased that we have been able to move the product so quickly through       
research and development and meet our goal of providing this innovative therapy 
to patients.”                                                                   

The approval is based on results from a pivotal study in which 42% of patients  
with CLL who were refractory to both fludarabine and alemtuzumab (two therapies 
used in treating CLL) responded to treatment with Arzerra.  These patients had a
median duration of response of 6.5 months. The most common adverse reactions    
(≥10%) seen were neutropenia, pneumonia, pyrexia, cough, diarrhea, anemia,      
fatigue, dyspnea, rash, nausea, bronchitis, and upper respiratory tract         
infections.  The most common serious adverse reactions seen were infections     
(including pneumonia and sepsis), neutropenia, and pyrexia.                     

“Arzerra is a significant step forward in helping patients and physicians better
manage the challenges of refractory CLL. Patients now have a new choice,” said  
Kathy Rouan, Ph.D., Vice President and Medicines Development Leader at          
GlaxoSmithKline.  “The Arzerra approval demonstrates the commitment of the GSK  
BioPharm and Oncology Units to developing new biopharmaceutical treatment       
options for cancer patients.”                                                   

Arzerra is a monoclonal antibody that causes the body's immune response to fight
against normal and cancerous B-cells.  Arzerra attaches to the small and large  
loop epitopes - on a molecule called CD20, which is found on the surface of     
B-cells, the type of cell which becomes cancerous in CLL.                       

The approval of Arzerra was supported by a positive recommendation by the FDA's 
Oncologic Drugs Advisory Committee (ODAC) at ASCO on May 29, 2009, in which the 
panel voted, 10-3, that the Arzerra data were likely to predict clinical benefit
for patients with CLL whose disease is refractory to fludarabine and            
alemtuzumab.                                                                    

Arzerra is anticipated to be available for prescription use in the coming weeks.

Access, and has expanded the program. This program assists eligible patients,
