COPENHAGEN, Denmark | Mar 12, 2007 |
TopoTarget A/S (CSE: TOPO) announced today that it has executed its in-licensing option from Novartis Pharma AG of Switzerland, for the development and marketing of ZemabR, an antibody based anti-cancer drug. According to the option and licensing agreement originating from 2003, TopoTarget now holds the world-wide and exclusive rights for the development of this product.

"I am happy to announce execution of this option. ZemabR has shown potential as a cancer drug in our preclinical models – and in a pilot study where ZemabR was injected directly into tumors in cancer patients with responses seen in 6 out of 10 patients. ZemabR has also successfully been evaluated in a phase I i.v. clinical trial. We are now ready to proceed in the development of ZemabR and next step will be to explore the possibilities in treating breast cancer patients," says Peter Buhl Jensen, CEO of TopoTarget.

ZemabR is a recombinant antibody-toxin for the treatment of specific types of cancers. This drug targets the ERBB2/HER2 receptor, which plays a central role predominantly in the development of breast cancer, but is also believed to be involved in selected other cancer indications, e.g. head and neck cancer. Initial clinical studies have demonstrated a reduction in tumor size after injection of ZemabR directly into ERBB2/HER2-positive tumors. Following a currently ongoing GMP (Good Manufacturing Practice) compliant production of ZemabR, new clinical studies will commence.
