This information is provided directly by researchers and we recognise that it isn't always easy to understand. We are working with researchers to improve the accessibility of this information.

PARC is an international phase I/II trial evaluating the safety and activity of pegylated recombinant human arginase (BCT-100) in children and young people with relapsed/refractory leukaemia, neuroblastoma, sarcoma and high grade gliomas (brain cancers). Currently the outcomes for these patients are poor and the therapeutic options are limited with a significant toxicity burden. Therefore new treatments which work in different ways to standard chemotherapy are urgently needed. Research has shown that arginine (a nutrient) is important in the survival of cancer cells. BCT-100 is a drug which can deplete arginine levels and starve cancer cells - a completely new approach. BCT-100 has been tested in adults and shown to be active with almost no side-effects. This trial will test whether this dose of BCT-100 is also safe and active in children with relapsed/refractory leukaemia, neuroblastoma, sarcoma and high grade glioma. The trial will also study how BCT-100 is broken down in the body and look for new biological markers of treatment response. Up to 64 children with relapsed cancers will be recruited over 2 years.

Start dates may differ between countries and research sites. The research team are responsible for keeping the information up-to-date.
