Positive results in AML with belinostat and idarubicin -Data were presented at American Society of Hematology (ASH) meeting in San Francisco Dec 6-9, 2008- Copenhagen, Denmark - December 8, 2008- TopoTarget A/S (OMX: TOPO) announces that belinostat monotherapy and belinostat in combination with idarubicin shows promising effect in acute leukemia in an ongoing Phase I/II international study. “These are remarkable results obtained in a very difficult to treat population of elderly patients who usually do not tolerate intensive chemotherapy.” Said professor Peter Buhl Jensen, MD and CEO of TopoTarget. “In our labs we have seen surprisingly good effect of prolonged belinostat administration and one of the promising results of this study is a complete response obtained in a patient treated with belinostat monotherapy as a 48 hours continuous infusion (CIV). It is a completely new way of administering this drug type. We have patented the invention and it is very promising that we already in phase I can see a clear anticancer effect. Peter Buhl Jensen continues: “Belinostat is the only compound in its class that can be given as a capsule, intravenous (IV) and now also as continuous infusion (CIV).This additional new way of administering belinostat could be clinically and commercially advantageous in certain cancers.” TopoTarget A/S For further information, please contact: Ulla Hald Buhl Telephone +45 39 17 83 92 Director IR & Communications Mobile +45 21 70 10 49
