Summary
This study is for patients with neuroblastoma, sarcoma, uveal melanoma, breast cancer, or another cancer that expresses a substance on the cancer cells called GD2. The cancer has either come back after treatment or did not respond to treatment. Because there is no standard treatment at this time, patients are asked to volunteer in a gene transfer research study using special immune cells called T cells. T cells are a type of white blood cell that helps the body fight infection. The body has different ways of fighting infection and disease. No single way seems perfect for fighting cancers. This research study combines two different ways of fighting cancer: antibodies and T cells. Both antibodies and T cells have been used to treat patients with cancers. They have shown promise but have not been strong enough to cure most patients. We have found from previous research that we can put a new gene into T cells that will make them recognize cancer cells and kill them. In our last clinical trial we made a gene called a chimeric antigen receptor (CAR) from an antibody that recognizes GD2, a substance found on almost all neuroblastoma cells (GD2-CAR). We put this gene into the patients' own T cells and gave them back to 11 neuroblastoma patients. We saw that the cells did grow for a while, but started to disappear from the blood after 2 weeks. We think that if T cells are able to last longer they may have a better chance of killing GD2 positive tumor cells. Therefore, in this study we will add a new gene to the GD2 T cells that can cause the cells to live longer. T cells need substances called cytokines to survive and the cells may not get enough cytokines after infusion. We have added the gene C7R that gives the cells a constant supply of cytokine and helps them to survive for a longer period of time. In other studies using T cells, investigators found that giving chemotherapy before the T cell infusion can improve the amount of time the T cells stay in the body and therefore the effect the T cells can have. This is called lymphodepletion and we think that it will allow the T cells to expand and stay longer in the body, and potentially kill cancer cells more effectively. The GD2-C7R T cells are an investigational product not approved by the Food and Drug Administration. The purpose of this study is to find the largest safe dose of GD2-C7R T cells, and also to evaluate how long they can be detected in the blood and what affect they have on cancer.

Criteria
Procurement Inclusion Criteria:

1. Evaluable neuroblastoma with persistent or relapsed disease

1. Recurrent disease following completion of aggressive multi-drug frontline
therapy.

2. Progressive disease during aggressive multi-drug frontline therapy.

3. Primary resistant/refractory disease (less than partial response by INRC)
detected at the conclusion of at least 4 cycles of aggressive multi-drug
induction chemotherapy on or according to a standard high-risk treatment protocol

OR Relapsed or refractory osteosarcoma not responsive to standard treatment

OR Patients diagnosed with GD2 positive metastatic uveal melanoma and progressed after
at least one prior systemic treatment

OR GD2 positive breast cancer with metastatic or locally recurrent unresectable breast
cancer currently progressive after at least two prior lines of therapy in the advanced
setting. Patients with HER2+ disease must have failed two or more different anti-HER2
agents.

OR Patients with other relapsed or refractory solid tumors not responsive to standard
treatment with confirmed expression of GD2 by immunohistochemistry testing.

2. Life expectancy of at least 12 weeks

3. Karnofsky/Lansky score of 50% or greater

4. Absence of human anti-mouse antibodies (HAMA) prior to enrollment (only in patients
that have been previously treated with murine antibodies)

5. Informed consent and assent (as applicable) obtained from parent/guardian and child

6. Greater than 1 and less than 75 years of age

Treatment Inclusion Criteria:

1. Neuroblastoma with persistent or relapsed disease

1. Recurrent disease following completion of aggressive multi-drug frontline
therapy.

2. Progressive disease during aggressive multi-drug frontline therapy.

3. Primary resistant/refractory disease (less than partial response by INRC)
detected at the conclusion of at least 4 cycles of aggressive multi-drug
induction chemotherapy on or according to a standard high-risk treatment
protocol.

OR Relapsed or refractory osteosarcoma not responsive to standard treatment

OR Patients diagnosed with GD2 positive metastatic uveal melanoma and progressed after
at least one prior systemic treatment

OR GD2 positive breast cancer with metastatic or locally recurrent unresectable breast
cancer currently progressive after at least two prior lines of therapy in the advanced
setting. Patients with HER2+ disease must have failed two or more different anti-HER2
agents.

OR Patients with other relapsed or refractory solid tumors not responsive to standard
treatment with confirmed expression of GD2 by immunohistochemistry testing.

2. Life expectancy of at least 12 weeks

3. Karnofsky/Lansky score of 50% or greater

4. Patients must have an ANC ≥ 500, platelet count ≥ 20,000

5. Pulse Ox ≥ 90% on room air

6. AST and ALT less than 5 times the upper limit of normal (less than 10 times upper
normal if uveal melanoma with metastatic liver disease)

7. Total bilirubin less than 3 times the upper limit of normal

8. Serum creatinine less than 3 times upper limit of normal. Creatinine clearance is
needed for patients with creatinine greater than 1.5 times upper limit of normal.

9. At least 4 weeks from completion and recovered from acute effects of all prior

associated thrombocytopenia), the patient must be clinically stable and meet all other
eligibility criteria. Maintenance therapy with non-investigational oral antineoplastic
drugs is allowed up to 48 hours prior to infusion.

applicable, CT/MRI/LP not required)

Treatment Exclusion Criteria

1. Currently receiving other investigational drugs.

2. Received any investigational immunotherapies or checkpoint inhibitors within 6 weeks.
Immunotherapies include adoptive cell therapies, gene therapies, and tumor vaccines.

Additionally, patients with bilateral pulmonary infiltrates on imaging may be enrolled
if the lesions are not consistent with active neuroblastoma (i.e., negative on
functional imaging with PET or MIBG, or by pathologic assessment) or not bulky in
other diseases (< 5 cm for each lesion) and patient meet FiO2 criteria (>90% on room
