CT Antigen TCR-redirected T Cells for Ovarian Cancer.
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.
Stanford is currently not accepting patients for this trial.
- Biological: NYESO-1c259 T cells
Phase 1/Phase 2
- 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:
1. prior immunotherapy, or prior investigational agents should be washed out 4 weeks
before apheresis and must be completed 4 weeks prior to pre-infusion
2. monoclonal antibody therapy must be completed at least 6 weeks prior to
pre-infusion lymphodepletive chemotherapy
3. 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.
4. 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
5. 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.
6. 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
- creatinine clearance > 60 mL/min for patients with creatinine levels above
- 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.
- 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
- 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
- Lack of availability of a patient for immunological and clinical follow-up assessment
- Evidence or history of significant cardiac disease
