Summary

This trial is for patients with solid tumors that have a protein called GPC3 on the surface of the tumor cells.

Who is the study for?
This trial is for children and young adults aged 1 to 21 with certain solid tumors like liver cancer, rhabdoid tumor, or Wilms tumor that have not responded to standard treatments. Participants need a minimum level of physical functioning (Lansky/Karnofsky score ≥60%), adequate organ function, and must not be pregnant or breastfeeding. They should also have no history of severe allergic reactions to mouse proteins.
What is being tested?
The trial tests AGAR T cells, which are genetically engineered immune cells designed to target GPC3-positive solid tumors in pediatric patients. These T cells include a chimeric antigen receptor (CAR) targeting the GPC3 protein on cancer cells and IL15 for enhanced performance. The study aims to determine the highest safe dose, how long these cells last in the body, their side effects, and effectiveness against the tumors.
What are the potential side effects?
Potential side effects may include an immune response where the body attacks its own tissues (autoimmunity), symptoms similar to flu such as fever and fatigue due to immune activation (cytokine release syndrome), neurological issues like confusion or seizures, blood cell count changes leading to increased infection risk or bleeding problems.
