Brief Summary

This phase I trial studies the best dose and side effects of NY-ESO-1 T cell receptor (TCR) engineered T cells and how well they work with NY-ESO-1 TCR engineered hematopoietic stem cells (HSCs) after melphalan conditioning regimen in treating patients with ovarian, fallopian tube, or primary peritoneal cancer that has come back (recurrent) or does not respond to treatment (refractory). The melphalan conditioning chemotherapy makes room in the patient's bone marrow for new blood cells and blood-forming cells (stem cells) to grow. Giving NY-ESO-1 TCR T cells 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. Giving NY-ESO-1 TCR engineered T cells and HSCs after melphalan may work better in treating patients with ovarian, fallopian tube, or primary peritoneal cancer.

Detailed Description

PRIMARY OBJECTIVES:

I. To assess the safety and feasibility of intravenous infusion of autologous peripheral blood mononuclear cells (PBMC) and CD34+ peripheral blood stem cells (PBSC) that have been genetically modified ex vivo to express NY-ESO-1 TCR, following a myeloablative conditioning regimen.

Ia. Assessment of toxicities using Common Toxicity Criteria (CTC) and definition of a maximum tolerated dose (MTD).

SECONDARY OBJECTIVES:

I. TCR engineered hematopoietic stem cell (HSC) engraftment. II. Functional assays for TCR transgenic cells. III. Progression-free survival (PFS) (compare with the duration of the PFS in the last treatment regimen).

IV. Durable tumor response in at least 30% of the patients defined as immune-related complete response (irCR) or immune-related partial response (irPR) by immune-related Response Evaluation Criteria in Solid Tumors (irRECIST) criteria at 6 months.

V. Long-term persistence of TCR transgenic cells (regardless of cell origin) as evidenced by \> 5% of CD3 lymphocytes being NY-ESO-1 specific by major histocompatibility complex (MHC) tetramer assay at 3 and 6 months.

VI. Discrimination of TCR transgenic cells resulting from retrovirally-transduced mature lymphocytes and lentivirally-transduced HSCs and their phenotyping.

VII. Long term monitoring for replication competent retrovirus and lentivirus. VIII. Analysis of viral insertion sites in long term persisting NY-ESO-1 TCR clones: absence of a clonal expansion of TCR transgenic cells with a particular transgene insertion site (defined as a clone comprising \> 20% of all PBSC-derived gene-marked cells).

IX. Gut microbiota pre and post treatment to evaluate the role of microbiota on the therapeutic efficacy of the proposed therapy.

OUTLINE: This is a dose-escalation study of autologous NY-ESO-1-specific CD8-positive T lymphocytes.

Patients receive melphalan intravenously (IV) over 30 minutes on day -1. Patients then receive autologous NY-ESO-1 CD4-TCR CD34+ HSC IV on day 0 and autologous NY-ESO-1-specific CD8-positive T lymphocytes IV between days 7 and 21. Patients also receive aldesleukin subcutaneously (SC) twice daily (BID) for 14 days on the following day after the T cell infusion (between days 8 and 22).

After completion of study treatment, patients are followed up every 6 months for 5 years, then annually for up to 15 years.

• Must have measurable disease as defined by Response Evaluation Criteria in Solid Tumors (RECIST) 1.1
• Must have adequate venous access for apheresis (pheresis catheter placement for cell collection is allowed)
• Since the study drug may affect pregnancy since it targets proteins present during development, women of childbearing potential are requested to use acceptable methods of birth control for the duration of the study and until persistence of the study drug is no longer detected in the patient by polymerase chain reaction (PCR). This may be a period of several years. Methods for acceptable birth control include: condoms, diaphragm or cervical cap with spermicide, intrauterine device, and hormonal contraception. It is recommended that a combination of two methods be used
• Leukocytes >= 3 x 10^9/L
• Absolute neutrophil count >= 1.5 x 10^9/L
• Platelets >= 100 x 10^9/L
• Total bilirubin within normal institutional limits
• Aspartate aminotransferase (AST) (serum glutamic-oxaloacetic transaminase [SGOT])/alanine aminotransferase (ALT) (serum glutamate pyruvate transaminase [SGPT]) =< 2.5 x institutional upper limit of normal
• Creatinine =< 2 x upper limit of normal (ULN); if creatinine level > 2 x ULN, then creatinine clearance must be > 60 mL/min
• Patient must understand the investigational nature of this study and sign an Independent Ethics Committee/Institutional Review Board approved written informed consent form prior to receiving any study related procedure
• Participant must agree to and arrange for a caregiver (age >= 18 years old) available 24 hours a day/ 7 days a week and arrange for lodging within 45 minutes drive to Roswell Park and transportation for a period of time after discharge from the hospital. The exact amount of time will depend on the individual status as determined by the treating physician

Exclusion Criteria

• Patients may not be receiving any other investigational agents

• Known cases of clinically active brain metastases (brain magnetic resonance imaging [MRI] as clinically indicated). 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

• History of allergic reactions attributed to compounds of similar chemical or biologic composition to agents used in the study

• Prior malignancy (except non melanoma skin cancer) within 3 years

• Uncontrolled intercurrent illness including, but not limited to, ongoing or active infection, or psychiatric illness/social situations that would limit compliance with study requirements

• Use of chronic corticosteroids, hydroxyurea, or immunomodulating agents (e.g., interleukin 2, interferon alpha or gamma, granulocyte colony stimulating factors, etc.) within 30 days prior to study entry

  • NOTE: Recent or current use of inhaled steroids and topical steroids are not exclusionary. If subjects are prescribed a brief course of oral corticosteroids, the use should be limited to less than 7 days. Use of steroids before apheresis and immune assessment blood draws should be discouraged as it will affect white blood cell function

• Active infection with human immunodeficiency virus (HIV), hepatitis B virus (HBV), hepatitis C virus (HCV), or cytomegalovirus (CMV) as defined below, due to the immunosuppressive effects of chemo-conditioning used and the unknown risks associated with viral replication

  • Positive serology for HIV
  • Active hepatitis B infection as determined by test for hepatitis B surface antigen (Ag)

If the HCV antibody is positive, a screening HCV ribonucleic acid (RNA) by any reverse transcriptase (RT) PCR or branched deoxyribonucleic acid (bDNA) assay must be performed at screening by a local laboratory with a Clinical Laboratory Improvement Act (CLIA) certification or its equivalent. Eligibility will be determined based on a negative screening value.
