CT Antigen TCR-redirected T Cells for Ovarian Cancer.

Completed · Phase 1/Phase 2

Conditions studied: Ovarian Cancer

In brief

This study, will take a subject's "T cells" and "teach" them to be able to recognize and attack the ovarian cancer cells. This is done by putting in a gene or genetic material that will change how a subject's T cells work and hopefully get them to attack and kill ovarian cancer cells. These new T cells are called "engineered T cells" because the new gene is causing them to become directed toward the ovarian cancer cells rather than their usual targets. These are also called "gene-modified T cells". For subjects who have the HLA A2 tissue-type marker, the T cells would be engineered to recognize a substance called "NY-ESO-1". After putting this new gene in T cells (a procedure called "gene therapy") the investigators will grow the cells in the laboratory and give these cells back to subjects.

Who can join

Age: 18 and older. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

• Must have a diagnosis of recurrent epithelial ovarian, primary peritoneal or fallopian tube carcinoma with refractory or platinum resistant disease and/or have received ≥ 2 lines of chemotherapy
• Age ≥ 18 years of age
• No significant immunodeficiency
• Have been informed of other treatment options
• Must be HLA A*0201, HLA-A*0205, and/or HLA-A*0206 positive by high resolution testing.
• Patient's tumor must be positive by histological assay for NY-ESO-1ᶜ²⁵⁹T, according to the screening algorithm as described in Section 3.3.1. Positive expression is defined as ≥ 50% of cells that are 2+ and/or 3+ by immunohistochemistry
• ECOG performance status of 0 or 1
• Life expectancy of > 4 months
• Prior therapies:
• prior immunotherapy, or prior investigational agents should be washed out 4 weeks before apheresis and must be completed 4 weeks prior to pre-infusion lymphodepletive chemotherapy.
• monoclonal antibody therapy must be completed at least 6 weeks prior to pre-infusion lymphodepletive chemotherapy
• All previous cytotoxic chemotherapy, monoclonal antibody therapy, immune therapy should be washed out 3 weeks before apheresis and must be completed at least 3 weeks prior to pre-infusion lymphodepletive chemotherapy.
• Systemic corticosteroid or other immunosuppressive therapy should be washed out 2 weeks before apheresis and must be completed at least 2 weeks prior to pre-infusion lymphodepletive chemotherapy
• Biologic or other approved molecular targeted small molecule inhibitors should be washed out 1 week before apheresis and must be completed at least 1 week prior to pre-infusion lymphodepletive chemotherapy.
• Any grade 3 or 4 -hematologic toxicity of previous therapy must have resolved to grade 2 or less prior to apheresis and any grade 3 or 4 toxicity must have resolved to grade 2 or less prior to pre-infusion lymphodepletive chemotherapy.
• Must have measurable disease as defined by RECIST 1.1.
• Must have adequate venous access for apheresis.
• 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. 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.
• Patients must have normal organ and marrow function as defined below:
• Leukocytes ≥ 3,000/mcL
• Absolute Neutrophil Count ≥ 1,500/mcL
• Platelets ≥ 100,000/mcL
• Total bilirubin ≤ 1.5 ULN
• AST(SGOT)/ALT(SGPT) ≤ 2.5 X institutional upper limit of normal
• creatinine ≤ 2.0 mg/dL OR

You may not qualify if…

• Currently receiving any other investigational agents
• Patients with active brain metastases. Patients with prior history of brain metastasis who have undergone local therapy (i.e. metastatectomy and/or radiation) and show no evidence of local recurrence or progression over the past 6 months are eligible
• History of allergic reactions attributed to compounds of similar chemical or biologic composition to cyclophosphamide or other agents used in the study
• Prior malignancy (except non-melanoma skin cancer) within 18 months of study entry NOTE: Patients must be in complete remission from prior malignancy in order to be eligible to enter the study.
• Uncontrolled intercurrent illness including, but not limited to, ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, 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. Use of steroids before apheresis and immune assessment blood draws should be discouraged as it will affect white blood cell function.
• Active infection with HIV, HBV or HCV
• Receipt of an experimental vaccine within 2 months or in the opinion of the Investigator is responding to an experimental vaccine given within 6 months, or has received any previous gene therapy using an integrating vector
• History of severe autoimmune disease requiring steroids or other immunosuppressive treatments
• Lack of availability of a patient for immunological and clinical follow-up assessment
• Evidence or history of significant cardiac disease
