Brief Summary

This phase I trial studies the side effects of genetically modified T cells and decitabine in treating patients with recurrent or refractory epithelial or non-epithelial ovarian, primary peritoneal, or fallopian tube cancer that has come back or has not responded to previous treatments. White blood cells called T cells are collected via a process called leukapheresis, genetically modified to recognize and attack tumor cells, then given back to the patient. Decitabine may induce and increase the amount of the target protein NY-ESO-1 available on the surface of tumor cells. Giving genetically modified T cells and decitabine may kill more tumor cells.

Detailed Description

PRIMARY OBJECTIVES:

I. To determine the safety and tolerability of the autologous NY-ESO-1 redirected T cell therapy in combination with decitabine and low-dose IL-2 in patients with treatment refractory or recurrent epithelial or non-epithelial ovarian, primary peritoneal or fallopian tube carcinoma.

SECONDARY OBJECTIVES:

I. To evaluate the persistence of genetically modified cells in the peripheral blood, and at tumor sites.

II. To examine the effect of the treatment on tumor as measured by objective tumor response and progression free survival, both assessed by immune-related Response Evaluation Criteria in Solid Tumors (irRECIST).

III. To assess the occurrence of target antigen and/or major histocompatibality complex (MHC) loss variants upon disease recurrence.

TERTIARY OBJECTIVES:

I. To evaluate the post treatment phenotype and functionality of genetically modified T cells isolated from peripheral blood and from tumor sites.

II. To assess changes in immunoscore, Tregs, Myeloid cell subsets, and antigen spreading in peripheral blood and tumor site.

III. To assess the influence of demographic and disease molecular characteristics on treatment outcomes of complete response (CR) and overall survival (OS).

OUTLINE:

COURSE 1: Patients receive decitabine IV daily over 1 hour on days -8 to Day -6, cyclophosphamide IV over 2 hours on days -4 and -3, and genetically engineered NY-ESO-1-specific T lymphocytes IV and intraperitoneally (IP) on day 0. Followed by low-dose IL-2 for 2 weeks from Day 1 to Day 14..

After completion of study treatment, patients are followed up monthly at 3-9 months, every 6 months for 4 years, and then annually for up to 15 years.

Exclusion Criteria

• Patients receiving any other investigational agents

• Patients with active brain metastases should be excluded from this clinical trial; patients with prior history of brain metastasis who have undergone local therapy (i.e., metastasectomy and/or radiation) and show no evidence of local recurrence or progression over the past 6 months are eligible. Brain MRI as clinically indicated only

• History of allergic reactions attributed to compounds of similar chemical or biologic composition to cyclophosphamide, decitabine or other 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 is not exclusionary; if subjects are prescribed a brief course of oral corticosteroids, the use should be limited to less than 7 days

• 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 cyclophosphamide used and the unknown risks associated with viral replication

Clinical response rates	Up to 15 years	Percentage of complete and partial responses and the corresponding 95% confidence interval will be calculated.
Duration of response	Up to 15 years	Will be observed.
Immunological parameters associated with T cell persistence, bioactivity and functionality	Up to 15 years	Will measure the pre- and post-treatment percentage of transgenic T cells in the peripheral blood, selective migration into the tumor sites, the ex-vivo immune functionality and phenotype of these cells, the modulation of cytokine milieu in serum post treatment as compared to baseline as well as the development of an expanded patient immune response against tumor via epitope spreading.
Overall survival	Up to 15 years	Will be observed.
Progression free survival	Up to 15 years	The median progression free survival and the corresponding 95% confidence interval will be calculated.
