Peds CHAMP1ON - Hematopoietic Stem Cell And Monoclonal Antibody PD-1 Blockade for RecurreNt Pediatric High-Grade Glioma

Study Purpose

This is a Phase I study of ex vivo expanded CD34+ hematopoietic stem cells (exHSCs) plus nivolumab in pediatric patients with histologically confirmed diagnosis of a non-brainstem high-grade glioma (NB-HGG, WHO Grade III or IV astrocytoma, oligodendrogliomas, oligoastrocytomas, ependymomas) that is recurrent, progressive or refractory following radiotherapy with or without chemotherapy. Patients must be candidates for standard of care surgical resection or biopsy.

Study Type

An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes.


An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes.


Searching Both is inclusive of interventional and observational studies.

Should a woman become pregnant or suspect she is pregnant while she or her partner is participating in this study, she should inform her treating physician immediately. Men treated or enrolled on this protocol must also agree to use adequate contraception prior to the study, for the duration of study participation, and 5 months after completion of nivolumab administration. Female subjects of childbearing potential must not be pregnant or breast-feeding. Female patients of childbearing potential must have a negative serum or urine pregnancy test within 72 hours prior to receiving the first dose of study medication. If the urine test is positive or cannot be confirmed as negative, a serum pregnancy test will be required.

  • - Patients with uncontrolled intercurrent illness or any other significant condition(s) (serious infections or significant psychiatric, cardiac, pulmonary, hepatic, or other organ dysfunction that in the opinion of the investigator would compromise the patient's ability to tolerate protocol therapy, put them at additional risk for toxicity, or would interfere with the study procedures or results.

Additional Details

This is a Phase I study of ex vivo expanded CD34+ hematopoietic stem cells (exHSCs) plus nivolumab in pediatric patients with recurrent high-grade glioma. One cycle will be 28 days in length with exHSCs + Nivolumab being administered on day 1 and Nivolumab alone being administered on day 15 of each cycle for a total of 10 cycles. Nivolumab may continue for a total two years of therapy, at the discretion of the treating team. There are two arms: Arm 1

  • - Immediate maximal surgical resection or biopsy, untreated tumor.
exHSCs and Nivolumab will be administered after maximal surgical resection. Arm 2
  • - exHSCs + Nivolumab will be administered prior to maximal surgical resection or biopsy.
exHSCs + Nivolumab will be administered after surgery.
