Oncurious NV, an emerging oncology company focused on the development of innovative orphan drugs for the treatment of pediatric cancers, announces it has initiated a Phase I/IIa study that will evaluate the safety and tolerability and explore the preliminary efficacy of TB-403 for the treatment of relapsed or refractory medulloblastoma, a rare, life-threatening brain tumor that mainly affects children.
Today’s study initiation follows the earlier announced partnership between Oncurious, its TB-403 project partner BioInvent, and the Neuroblastoma and Medulloblastoma Translational Research Consortium (NMTRC) in the US. NMTRC is a collaboration of 25 US academic medical centers, teaching hospitals and other entities, with the purpose of facilitating and conducting collaborative research activities and investigations of new treatments for neuroblastoma, medulloblastoma and other pediatric cancers.
Headquartered at the Helen DeVos Children’s Hospital in Grand Rapids, MI, USA, NMTRC is the key clinical trial partner for this Phase I/IIa study. The study aims at recruiting a minimum of 27 patients, with first results expected to be reported in 2017.
TB-403 is a humanized monoclonal antibody against placental growth factor (PlGF) which is expressed in several types of cancer, including medulloblastoma. A paper in Cell in February 2013 (Cell, 152, 1065-76, 2013), highlighted for the first time that PlGF plays a role in the growth of medulloblastoma. The paper was based on pre-clinical research conducted by Prof Rakesh Jain from the Massachusetts General Hospital at Harvard (Boston) and the team of Prof Peter Carmeliet from the VIB/ KU Leuven.
