Study Summary

This trial is testing genetically-modified T cells to treat solid tumors in children and young adults. The goal is to evaluate safety and feasibility, and to determine if the cells can kill tumors.

Eligible Conditions
  • Wilms Tumor
  • Solid Tumor Pediatric
  • Malignant Peripheral Nerve Sheath Tumour (MPNST)
  • Neuroblastoma
  • Retinoblastoma
  • Desmoplastic Small Round Cell Tumor
  • Soft Tissue Sarcoma (STS)
  • Rhabdoid Tumor
  • Ewing Sarcoma
  • Carcinoma
  • Clear Cell Sarcoma of Soft Tissue
  • Hepatoblastoma
  • Germ Cell Tumors
  • Synovial Sarcoma
  • Osteosarcoma
  • Rhabdomyosarcoma

Treatment Effectiveness

Study Objectives

3 Primary · 2 Secondary · Reporting Duration: 84 days

28 Days
Establish the safety, defined by adverse events, of EGFR806-specific CAR T cell infusions (Arm A), and of dual transduced EGFR806xCD19 CAR T cell infusions (Arm B)
The number of successfully manufactured EGFR806 and EGFR806xCD19 CAR T cell products will be assessed
28 days
Estimate the maximum tolerated dose (MTD) and dose limiting toxicities (DLT), and describe the full toxicity profile of the two CAR T cell products
84 Days
Number of Arm A and Arm B subjects with persistence of CAR T cells in the peripheral blood at each visit time point
To quantitate anti-tumor responses by measuring changes in tumor burden using disease-specific evaluations and describe survival characteristics following CAR T cell infusion
84 days
Number of Arm A and Arm B subjects with persistence of CAR T cells in the bone marrow at each visit time point

Eligibility Criteria

Age < 65 · All Participants · 10 Total Inclusion Criteria

Mark “yes” if the following statements are true for you:
This text is saying that someone is able to tolerate apheresis or they have apheresis product available for use in manufacturing.
You have a score of 50 or higher on the Lansky or Karnofsky score.
, then the patient should be retreated with aGVHD prophylaxis If there is no apheresis product or T cell product available, then the patient should be retreated with aGVHD prophylaxis at least 7 days after the last chemotherapy or biologic therapy administration.
This means that a person can expect to live for at least 8 weeks.
, she now experiences occasional shortness of breath and fluid retention After all the chemotherapy, immunotherapy, and radiotherapy she's been through, she occasionally experiences shortness of breath and fluid retention.
If no apheresis product or T cell product is available,≥ 3 half lives or 30 days, whichever is shorter, post last dose of anti-tumor antibody therapy (including check point inhibitor) is required.
The first two subjects who enrolled and were treated in both Arm A and Arm B were between the ages of 15 and 30 years old.
vIII A malignant, non-CNS solid tumor expressing EGFRvIII is a tumor that is histologically diagnosed as being malignant and that expresses the EGFRvIII protein.
