Summary

This trial studies the side effects and best dose of APX005M in treating younger patients with primary malignant central nervous system tumor.

Who is the study for?
This trial is for children and young adults aged 1 to 21 with primary malignant non-brainstem CNS tumors that are recurrent, progressive, or refractory, or those newly diagnosed with DIPG. Participants must have stable neurological deficits, adequate organ function, not be pregnant or breastfeeding, use effective contraception methods if applicable, and meet specific recovery criteria from previous treatments.
What is being tested?
The trial tests APX005M's safety and optimal dosage in treating aggressive brain tumors in the young. It activates immune cells and may directly kill tumor cells expressing CD40. The study includes patients with new diagnoses of diffuse intrinsic pontine glioma (DIPG) as well as those with recurring or resistant CNS tumors.
What are the potential side effects?
Potential side effects of APX005M include reactions related to immune activation such as inflammation in various organs; it might also cause cytotoxic effects on certain tumor cells which could lead to a range of symptoms depending on the affected area.
