DIPG

This study will evaluate BCB-276, an investigational B7-H3-targeted Chimeric Antigen Receptor (CAR) T cell therapy, in children and young adults with diffuse intrinsic pontine glioma (DIPG). DIPG is a rare and aggressive brain tumor with limited treatment options. CAR T cell therapy uses a patient's own immune cells that are changed in a laboratory to recognize and attack cancer cells. The purpose of this study is to determine whether BCB-276, when given after completion of standard radiation therapy, is safe and can improve survival for patients with DIPG. To participate, individuals must be between 1 and 26 years of age when they join the study, have a diagnosis of DIPG, and enroll for treatment within 6 weeks of completing initial radiation therapy. Participants must not have received prior anti-cancer therapy beyond radiation with or without temozolomide prior to joining this study. BCB-276 is administered intraventricularly (into the fluid around the brain), which requires placement of a catheter for treatment. BCB-276 is given every 2 weeks at a research center over a period of several months (approximately 7-8 months). Participation includes travel to a study site, procedures to support treatment administration, sample collection, and ongoing monitoring for safety and effectiveness, with follow-up visits lasting up to about 2 years.

Study in children and adolescents of 177Lu DOTATATE (Lutathera®) combined with the PARP inhibitor olaparib for treatment of recurrent or relapsed solid tumours expressing somatostatin receptors (SSTR) (LuPARPed)

In this study, we want to find out more about the side effects of an investigational drug for relapsed or refractory atypical teratoid rhabdoid tumor and high-grade glioma, Gallium Maltolate (GaM) and what doses of GaM are safe for people to take. Everyone in this study will receive GaM which is still experimental and is not approved by the U.S. Food and Drug Administration. We do not know all the ways that this drug may affect people. We hope the information from this study will help us develop a better treatment for relapsed or refractory atypical teratoid rhabdoid tumor and high-grade glioma in the future.

In this study, the investigators are testing improvement in survival outcomes in DIPG patients when stratified with MR perfusion score and treated with the said protocol. Newly diagnosed DIPG patients will undergo MRI perfusion study in addition to the usual MRI at diagnosis and will be stratified into hyperperfused or hypoperfused tumours. The hyperperfused patients will receive additional low dose Bevacizumab weekly with conventional standard radiotherapy. The hypo-perfused patients will receive ultra-low-dose radiotherapy fractionation equivalent to conventional RT biological dose.

This study will gather data from new and existing patients with patient medical records, and patient/family/caregiver reported information to establish a clear natural history of disease suitable to serve as an external, contemporary or historical control arm for future therapeutic development programs of drugs, devices, or biologic interventions in DMG or DIPG.
