Genetically Engineered Cells (FSHCER T cells) for the Treatment of Recurrent Platinum-resistant or Platinum-refractory Ovarian, Primary Peritoneal, or Fallopian Tube Cancer
This phase I trial tests the safety, side effects and best dose of autologous anti-FSHR CER-4-1BB/CD3zeta-expressing T-lymphocytes (FSHCER T cells) with or without conditioning chemotherapy in treating patients with ovarian, fallopian tube, or primary peritoneal cancer that has come back (recurrent), has come back after platinum-based chemotherapy (platinum-resistant), or has progressed during platinum-based chemotherapy (platinum-refractory). T cells are infection fighting blood cells that can kill tumor cells. The T cells given in this study will come from the patient and will have a new gene put in them that makes them able to recognize FSHR, a protein on the surface of tumor cells. These FSHR-specific T cells may help the body's immune system identify and kill FSHR expressing tumor cells. Drugs used in chemotherapy, such as cyclophosphamide and fludarabine, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving chemotherapy before FSHCER T cells helps kill cancer cells in the body and may help the FSHCER T cells last longer in the body.
Inclusion Criteria
- >= 18 years of age 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. The study does not include pure sarcomas. Tumors that are substantially high-grade carcinoma and have focal elements of sarcomatous elements (e.g., carcinosarcoma) are eligible
- Have measurable disease or detectable (non-measurable) disease * Measurable disease is defined as at least 1 lesion that can be accurately measured in at least 1 dimension (longest diameter to be recorded). Each lesion must be >= 10 mm when measured by computed tomography (CT), magnetic resonance imaging (MRI), or caliper measurement at clinical examination or >= 20 mm when measured by chest x-ray. Lymph nodes must be >= 15 mm in short axis when measured by CT or MRI * Detectable (non-measurable) disease is defined as not having measurable disease but having: ** Baseline values of CA-125 at least 2 x upper limit of normal AND EITHER *** Ascites and/or pleural effusion attributed to tumor OR *** Solid and/or cystic abnormalities on radiographic imaging consistent with recurrent disease that do not meet Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1 definitions for target lesions. The protocol is using immune-related (i)RECIST for response evaluation
- Patient consent to have tumor obtained for correlative study testing * Historical formalin-fixed paraffin-embedded (FFPE) and/or fresh or frozen tissue will be requested but it is not necessary to have obtained it or the results before enrollment; tissue FSHR positivity is not required for eligibility
- 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 Food and Drug Administration (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)
- Absolute neutrophil count (ANC) >= 1500/mm^3
- Platelets >= 100 000/mm^3
- No anticancer therapy (chemotherapy, biologic therapy, or immunotherapy) in the 3 weeks before the T-cell infusion (and all hematologic effects have resolved). No prior immunotherapy with checkpoint blockade (e.g., PD1 inhibitor, PDL1 inhibitor, or CTL4- antagonist or similar agent) in the 3 months before the T-cell infusion (and all clinically significant related side effects must be resolved)
- Patient agrees to undergo placement of surgically placed peritoneal port and central line catheter (may be temporary or subcutaneous)
- Although it is anticipated that patients who are eligible for this study will not have childbearing potential, any patient the treating doctor or investigator deems to have childbearing potential must agree to an acceptable means of contraception from the time of screening to at least 6 months after T-cell infusion
Exclusion Criteria
- Known active hepatitis B infection, known history of hepatitis C or human immunodeficiency virus (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 electrocardiogram (ECG) or echocardiogram (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 whole abdominopelvic radiotherapy. Limited fields (i.e. pelvic, nodal, solitary lesions) are acceptable
- Current pregnancy or lactation
- Any of the following within 28 days of first date of study treatment: * Serious uncontrolled medical illness or disorder that in the opinion of the treating physician would make the patient ineligible for the study * Active uncontrolled infection (with the exception of uncomplicated urinary tract infection) * Abdominal fistula, gastrointestinal perforation, or intraabdominal abscess * Abdominal surgery (for reasons other than IP port placement)
- Any other issue which, in the opinion of the treating physician or principal investigator, would make the patient ineligible for the study

Patients may receive a second treatment at the discretion of the principal investigator (PI) on study. Patients undergo echocardiography (ECHO)/multigated acquisition scan (MUGA) at screening and also undergo computed tomography (CT) or magnetic resonance imaging (MRI), biopsy, and collection of blood samples throughout the trial. Patients may also undergo collection of ascites fluid throughout the trial.
ARM II (COHORTS 5, 5B, AND 5C): Patients undergo leukapheresis and catheter placement at enrollment. Patients receive cyclophosphamide and fludarabine IV on days -5 to -3, and FSHCER T cells IP or IV infusion over 5 to 20 minutes on day 0. Patients may receive a second treatment at the discretion of the PI on study. Patients undergo ECHO/MUGA at screening and also undergo CT or MRI, biopsy, and collection of blood samples throughout the trial. Patients may also undergo collection of ascites fluid throughout the trial.
After completion of study treatment, patients are followed at 14 and 28 days, 8 weeks, every 3 months for 2 years, every 6 months for 3 years, and then every annually for up to 15 years
