Eligibility Criteria

• Age: 18 Years+
• Gender Eligibility Details: female participants only
• Healthy Volunteers: No
• Age Groups: Adult (18-64), Older Adult (65+)

You may qualify if:

• Aged 18 years or older and able to provide informed consent.
• Pathologically confirmed diagnosis of invasive (Grades 1-3) epithelial ovarian cancer, primary peritoneal cancer, or fallopian tube carcinoma (EOC), which are serous, endometrioid, clear cell, mucinous, mixed epithelial, or undifferentiated. Borderline serous ovarian tumors (BOT, also known as serous low-malignant potential tumors) are included, as are mixed invasive/borderline cancers. Patients may also have sex cord-stromal tumors (SCSTs) to include adult-type granulosa cell tumors (GCTs) and Sertoli Leydig cell tumors (SLCTs), or SCSTs with mixed elements that include at least one of these types.
• Have measurable disease or detectable (non-measurable) disease.
• Consent to have tumor obtained for correlative study testing.
• Patients must have had 1 prior platinum-based chemotherapeutic regimen for the management of ovarian, primary peritoneal, or fallopian tube carcinoma and at least 2 prior chemotherapy regimens.
• Patients should be considered platinum- refractory (progression while on a prior platinum chemotherapy) or resistant (persistence or recurrence within 6 months after a prior platinum chemotherapy) and be deemed unlikely to have significant benefit from any standard therapies by the treating investigator.
• Patients with a known germline or somatic BRCA pathogenic mutation should receive a PARP inhibitor if treatment would be consistent with the current FDA approval for use of PARPi at time of screening, unless they have a documented history of intolerance or inability to swallow oral medications.
• For Granulosa Cell Tumors (GCTs), at least one hormonal regimen (i.e., letrozole) should be included in prior therapies.
• For Borderline Ovarian Tumors, documentation of the consideration of a MEK inhibitor (e.g., trametinib) should be included.
• For high-grade serous (Grades 2,3), eligibility and consideration of Folate Receptor-alpha antibody drug conjugate (e.g., mirvetuxumab) should be considered and documented for patients who meet all FDA label criteria.
• Patients are allowed to receive, but are not required to receive, up to 6 additional prior (for a total of 8 prior treatments) chemotherapy treatment regimens (including platinum-based chemotherapy). Prior maintenance therapy with an agent when there has not been progression will not be a separate treatment regimen. Prior hormonal therapy is allowed, and when used alone, even as a therapeutic agent, it does not count toward this prior regimen requirement. Hormonal therapy must be discontinued at least 1 week before T-cell infusion. Continuation of hormone replacement therapy is permitted.
• Patients are allowed to receive, but are not required to receive, biologic/targeted therapy alone or as part of their treatment regimens. When used as treatment after progression, these treatments will count as a separate therapy.
• Eastern Cooperative Oncology Group (ECOG) status of 2 or better (or Karnofsky Performance Status score of ≥60%).
• Life expectancy of at least 3 months.
• Adequate bone marrow, renal, and hepatic function (liver function and renal tests, grade 1 or lower):

You may not qualify if:

• Known active hepatitis B infection, known history of hepatitis C or HIV infection.
• Clinical or radiographic evidence of bowel obstruction or need for parenteral hydration and/or nutrition.
• Known or suspected extensive abdominal adhesions that would preclude port placement or infusion.
• Any of the following cardiac conditions:
• Clinically significant heart disease (New York Heart Association class 3 or 4) or symptomatic congestive heart failure.
• Myocardial infarction \<6 months before enrollment. History of clinically significant ventricular arrhythmia or unexplained syncope that is not believed to be vasovagal in nature or due to dehydration.
• History of severe non-ischemic cardiomyopathy with ejection fraction \<20%. Findings on baseline ECG or ECHO that, in the opinion of the patient's treating physician or investigator, would require medical intervention before anticancer therapy
• Active autoimmune disease (excluding autoimmune thyroid disease on a stable thyroid regimen). Such conditions include but are not limited to systemic lupus erythematous, rheumatoid arthritis, ulcerative colitis, Crohn's disease, and temporal arteritis.
• Known or suspected leptomeningeal disease and patients with metastases to the brain stem, midbrain, pons, or medulla.
• Known or suspected untreated brain metastases. Patients with radiographically stable, asymptomatic previously irradiated lesions are eligible provided patient is \>4 weeks beyond completion of cranial irradiation and \>3 weeks off of corticosteroid therapy at the time of study intervention.
• Prior history of clinically significant seizure disorder (e.g., not including childhood febrile seizures).
• Any concurrent active malignancies, defined as malignancies requiring any therapy other than expectant observation, because adverse events (AEs) resulting from these malignancies or their treatment may confound our assessment of the safety of adoptive T-cell therapy for ovarian cancer.
• Prior radiotherapy to any portion of the abdominal cavity or pelvis.
• Current lactation or pregnancy
• Any of the following within 28 days of first date of study treatment:
