New Paper in Cell highlights the potential role of TB-403 (anti-PlGF) in the 
treatment of medulloblastoma, a pediatric brain tumor 
Leuven, 28 February 2013 – ThromboGenics NV (Euronext Brussels: THR), and 
co-development partner BioInvent International AB (OMXS: BINV), announce today 
the publication of a paper in the prestigious journal Cell, highlighting the 
potential of TB-403 to improve the treatment of medulloblastoma, the most 
common brain tumor in children. 
The Cell publication highlights for the first time a new mechanism of action 
showing that PlGF plays a vital role in the brain and that its expression is 
required for the growth and spread of medulloblastoma.      
The novel positive findings in this paper provide evidence that could warrant 
further development of TB-403 as one of the first targeted therapies to treat 
this childhood cancer. TB-403 is a monoclonal antibody against placental growth 
factor (PlGF). PIGF is a naturally occurring protein that belongs to the family 
of vascular endothelial growth factors (VEGF) that promote the formation of 
blood vessels. 
TB-403 was in-licensed by ThromboGenics from the Flanders Institute for 
Biotechnology (VIB), where the therapeutic potential of anti-PlGF agents to 
treat cancer was first developed by Prof. Peter Carmeliet at the University of 
Leuven, Belgium.
This Cell paper is reporting the findings of new pre-clinical research 
performed at the Massachusetts General Hospital in Harvard (Boston), in 
collaboration with the team of Prof Peter Carmeliet. 
With an emerging ophthalmologic franchise, Thrombogenics is also evaluating the 
role of TB-403 for ophthalmic indications.
