Phase:

PHASE1

Brief Summary

The purpose of this study is to find the largest safe dose of i15.NKG2D.zeta-NK cells in combination with C7R.GD2.CAR-T cells, and additionally to evaluate how long they can be detected in patients' b...

Detailed Description

To make the T cells, the investigators will take patient's blood and stimulate it with growth factors that make T cells grow. Investigators will use a retrovirus to insert the GD2-targeting chimeric a...
