PALADIN LABS SIGNS AGREEMENT FOR NOVEL BIOLOGIC TO TREAT NEUROBLASTOMA MONTREAL, CANADA -January 16, 2013 -Paladin Labs Inc. (TSX:PLB) announced today that it has entered into an exclusive licensing agreement with Apeiron Biologics AG for APN311, a novel, antibody-based immunotherapy for children with high-risk neuroblastoma. Under the terms of the agreement, Paladin has been granted the exclusive rights to market and sell APN311 in Canada and Sub-Saharan Africa (including South Africa). Further details or financial terms of the transaction were not disclosed.

Neuroblastoma is a malignant tumor that develops from nerve tissue. While the incidence of neuroblastoma is rare, after brain cancer, it is the most frequent solid cancer in children under five years of age and is the most common form of cancer affecting infants. In high-risk neuroblastoma, more than half of the patients receiving standard therapy have a relapse and ultimately die from the disease. Approximately
50-75 children a year are diagnosed with neuroblastoma in Canada accounting for about 12-15% of pediatric cancer deaths - the lowest survival rate out of all childhood cancers1.
APN311 is a monoclonal chimeric antibody (ch14.18) produced in CHO cells targeting the GD2 antigen on neuroblastoma cells and is currently undergoing a randomized Phase III in Europe. Furthermore, treatment of advanced neuroblastoma patients with APN311 has demonstrated substantial clinical activity2.
"APN311 has shown promise in improving survival rates in the treatment of children diagnosed with neuroblastoma," said Mark Beaudet, interim President and CEO of Paladin Labs Inc. "Paladin is proud to be working with Apeiron to make this important new treatment option available to patients in Canada and Sub-Saharan Africa."
"We are very excited to partner with Paladin, one of the leading Canadian specialty pharmaceutical companies, given its experience in rare and orphan diseases as well as its emerging focus in oncology. Paladin is well positioned to make APN311 a success in its territories", said Hans Loibner, President and CEO of Apeiron Biologics.
