TopoTarget Clarifies Status of Collaboration with LEO-
Pharma, in order to Fully Ensure Accurate and Full    
Information to the market                             

Copenhagen, Denmark - February 8, 2008- TopoTarget A/S (OMX:                    
TOPO) today wishes to clarify the status of the company's collaboration with LEO
Pharma concerning a pre-clinical compound for investigation for the treatment of
psoriasis. The clarification follows the publication of information connected   
with an interview with LEO Pharma, which appeared in the Danish newspaper Børsen
today.                                                                          
TopoTarget was informed on January 23 2008 that LEO Pharma planned to           
discontinue development of a very early stage pre-clinical compound originally  
in-licensed from TopoTarget for the treatment of psoriasis. Under the terms of  
the agreement the collaboration ends after a three month period on April 30     
2008.                                                                           
During the termination period a report concerning the project will be sent to   
TopoTarget by LEO Pharma.                                                       
TopoTarget wishes to state that information regarding pre-clinical programs with
insignificant financial and strategic impact on the company are normally        
announced in the Quarterly report.                                              
The HDACi (PXD 118490/LEO 80140) pre-clinical compound was out-licensed to LEO  
Pharma in 2006 for investigation for potential use in treating psoriasis. The   
compound will now revert to TopoTarget's pre-clinical team where further        
development opportunities will be consididered. This compound was one out of    
around 800 compounds in TopoTarget's pre-clinical library.                      

“Psoriasis is not a focus area for TopoTarget and this out-licensing agreement 
was part of our business development strategy to allow pharmaceutical companies
to investigate interesting compounds in early stage development efforts to find
new treatments.” Said Peter Buhl Jensen, CEO of TopoTarget. “TopoTarget is     
dedicated to finding treatments for cancer and the value of business is in our 
marketed product Savene®/Totect™ and in our robust clinical pipeline consisting
of belinostat and 8 additional products in Phase I and Phase II clinical       
development.”                                                                  

Today's news does not change TopoTarget's full-year financial guidance.
