Copenhagen, Denmark - 28 October, 2011 - Today Topotarget A/S (NASDAQ OMX: TOPO.CO) and Multimeric Biotherapeutics, Inc. (Multimeric) announced the signature of an exclusive license agreement granting Multimeric rights to the further development of the multimeric TNF superfamily ligands (TNFSFs) for all therapeutic uses. TNFSFs are not a core activity of Topotarget IP assets. Topotarget continue to focus efforts on its lead compound the HDACi belinostat.

Under the agreement, Multimeric will license the rights to all multimeric fusion proteins containing TNFSFs which are covered by Topotarget's issued and pending patents in Europe, US, Canada, Japan, Australia, South Korea, and other territories. The agreement also grants Multimeric the rights to sub-license.

"This agreement unifies the patent estates of our two companies for the therapeutic applications of the TNFSFs (other than FasL),"said Dr. Richard S. Kornbluth, President and Chief Scientific Officer of Multimeric. The key to the technology is a means for producing TNFSFs as highly active, many-trimer proteins. Included in the agreement are multimeric forms of CD40 ligand (CD40L), GITR ligand (GITRL), and other TNFSFs that are the subject of much current scientific and medical interest.

"By concluding this deal Topotarget is able to complement Multimeric's IP portfolio thereby enabling their continued global development within the TNFSFs' field", said Inge Lauritzen, VP of Business Development and Licensing at Topotarget.

No details on the terms of the agreement were disclosed.

Today's news does not change Topotarget's full-year financial guidance for 2011.
