About
This phase I clinical trial evaluates the safety and feasibility of administering NY-ESO-1 TCR (T cell receptor)engineered peripheral blood mononuclear cells (PBMC) and peripheral blood stem cells (PBSC) after a myeloablative conditioning regimen to treat patients with cancer that has spread to other parts of the body. The conditioning chemotherapy makes room in the patient?s bone marrow for new blood cells (PBMC) and blood-forming cells (stem cells) to grow. Giving NY-ESO-1 TCR PBMC and stem cells after the conditioning chemotherapy is intended to replace the immune system with new immune cells that have been redirected to attack and kill the cancer cells and thereby improve immune system function against cancer.
Full description
PRIMARY OBJECTIVE:
I. To determine the safety of administering the combination of autologous peripheral blood mononuclear cells (PBMC) and CD34+ peripheral blood stem cells (PBSC) following a reduced intensity conditioning regimen, both of which have been genetically modified to express NY-ESO-1 TCR.
SECONDARY OBJECTIVES:
I. To determine the feasibility of delivering the combination of TCR transduced autologous PBMC and CD34+ PBSC to patients.
II. To determine the persistence of NY-ESO-1 TCR transduced PBMC and the progeny of TCR transduced PBSC in serial peripheral blood samples.
III. Objective response rate (ORR).
EXPLORATORY OBJECTIVE:
I. To explore the use of positron emission tomography (PET)-based imaging using the PET tracer 9-4-[18F]fluoro-3-(hydroxymethyl)butylguanine ([18F]FHBG) with the goal of determining whether the adoptively transferred NY-ESO-1 TCR transduced PBSC home to bone marrow, differentiate into T cells and expand in secondary lymphoid organs and tumor deposits.
OUTLINE:
G-CSF AND PLERIXAFOR MOBILIZED LEUKAPHERESIS: Between 6 months and 3 weeks before infusion of cells, patients undergo G-CSF and plerixafor mobilization of CD34+ peripheral blood stem cells. Patients receive G-CSF subcutaneously (SC) on mobilization days 1-8 and plerixafor SC on mobilization days 4-7, during mobilization, patients will undergo mobilized leukapheresis to obtain PBSC. Patients also undergo an unmobilized leukapheresis on day -5 before infusion of cells in order to obtain PBMC.
CHEMOTHERAPY CONDITIONING REGIMEN: Patients receive busulfan intravenously (IV) on days -4 to -2 and fludarabine IV over 30 minutes on days -3 to -2.
Patients receive LV-NYESO TCR/sr39TK PBSC IV on day 0, and after approximately 24 hours, patients receive RV-NYESO TCR PBMC IV on day 1. Beginning on day 2, patients receive aldesleukin (interleukin-2 (IL) or IL-2) SC twice daily (BID) for up to 7 days. Patients undergo blood collection for safety and immune monitoring on days 0, 1, 3, 5, 7, 14, 30, 60, 90, and 120. Patients receive the PET tracer 18F-FHBG IV, and after 1 hour, undergo PET/computed tomography (CT) on days 25 and 120.
After completion of study treatment, patients are followed up every 2-3 months for 2 years, every 6 months for 5 years, and annually for 15 years.

Volunteers
Inclusion criteria
Stage IV or locally advanced unresectable cancers for which no alternative therapies with proven survival advantage are available
NY-ESO-1 positive malignancy by immunohistochemistry (IHC) utilizing commercially available NY-ESO-1 antibodies
HLA-A*0201 (HLA-A2.1) positivity by molecular subtyping
Age greater than or equal to 16 years old; if patients 16-17 years old are enrolled in the trial, they will only be enrolled after 3 patients >= 18 years old have been treated, and the treatment has been shown to be safe
A minimum of one measurable lesion defined as:
Eastern Cooperative Oncology Group (ECOG) performance status (PS) 0 or 1
Adequate bone marrow and major organ function to undergo a PBSC transplant determined within 30-60 days prior to enrollment using standard phase 1 criteria for organ function defined as:
Must be willing and able to accept at least three leukapheresis procedures
Must be willing and able to undergo three research PET scans
Must be willing and able to provide written informed consent
Exclusion criteria
Inability to purify >= 2.5 x 10^6 CD34-enriched cells/kg of patient weight from the pooled G-CSF mobilized leukapheresis products
Previously known hypersensitivity to any of the agents used in this study; known sensitivity to busulfan or fludarabine
Received systemic treatment for cancer, including immunotherapy, within 28 days prior to initiation of conditioning chemotherapy administration within this protocol
Potential requirement for systemic corticosteroids or concurrent immunosuppressive drugs based on prior history or received systemic steroids within the last 2 weeks prior to enrollment (inhaled or topical steroids at standard doses are allowed)
Human immunodeficiency virus (HIV) seropositivity or other congenital or acquired immune deficiency state, which would increase the risk of opportunistic infections and other complications during chemotherapy-induced lymphodepletion; if there is a positive result in the infectious disease testing that was not previously known, the patient will be referred to their primary physician and/or infectious disease specialist
Hepatitis B or C seropositivity with evidence of ongoing liver damage, which would increase the likelihood of hepatic toxicities from the chemotherapy conditioning regimen and supportive treatments; if there is a positive result in the infectious disease testing that was not previously known, the patient will be referred to their primary physician and/or infectious disease specialist
Dementia or significantly altered mental status that would prohibit the understanding or rendering of informed consent and compliance with the requirements of this protocol
Known clinically active brain metastases; prior evidence of brain metastasis successfully treated with surgery or radiation therapy will not be exclusion for participation as long as they are deemed under control at the time of study enrollment and there are no neurological signs of potential brain metastases
Pregnancy or breast-feeding; female patients must be surgically sterile or be postmenopausal for two years, or must agree to use effective contraception during the period of treatment and for 6 months afterwards; all female patients with reproductive potential must have a negative pregnancy test (serum/urine) within 14 days from starting the conditioning chemotherapy; the definition of effective contraception will be based on the judgment of the study investigators
Since IL-2 is administered following cell infusion:
Bone marrow involvement based on PET/CT scan at screening
Active or recent herpes simplex virus (HSV) infection or cytomegalovirus (CMV) based on symptoms with positive swab culture and/or positive IgM (immunoglobulin M) screening
Liver metastases with no other metastatic sites
