Summary

This trial is testing a new treatment for children with brain tumors that have come back or are resistant to treatment. The new treatment is a combination of chemotherapy and cellular immunotherapy, which uses brain-tumor specific cells to change the body's immune system.

See full description

Who is the study for?

This trial is for children with IL13Ralpha2 positive brain tumors that have returned or are not responding to treatment. They must have good kidney function, no severe infections, and a certain level of physical ability despite their illness. Children who are pregnant, breastfeeding, or unable to follow the study procedures cannot participate.Check my eligibility

What is being tested?

The trial tests chemotherapy (cyclophosphamide and fludarabine) combined with cellular immunotherapy using CAR T cells targeting IL13Ralpha2 on tumor cells. It aims to see if this combination can better kill tumor cells in children whose brain cancer has come back or isn't responding.See study design

What are the potential side effects?

Possible side effects include reactions from the immune system attacking normal tissues (autoimmunity), symptoms from cell infusions like fever and chills, low blood counts leading to increased infection risk, nausea from chemotherapy, and potential organ damage.

Experimental Treatment

Group I: Treatment (chemotherapy, IL13(EQ)BBzeta/CD19t+ T cells)Experimental Treatment3 Interventions

Patients receive cyclophosphamide intravenously IV on days -5 and -4, and fludarabine IV on days -5 to -2. Patients then receive autologous IL13(EQ)BBzeta/CD19t+ T cells intraventricularly over 5 minutes QW on day 0. Treatment with autologous IL13(EQ)BBzeta/CD19t+ T cells repeats every 7 days for up to 4 cycles in the absence of disease progression or unacceptable toxicity. Patients may receive additional cycles of IL13(EQ)BBzeta/CD19t+ T cells as long as they continue to meet eligibility criteria and have doses available for infusion.
