Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 18 to 80 years
  • Women only
  • No healthy volunteers
  • Adult, Older adult

Who may be able to join

  • 5.1.1 STEP 1: RESECTION OF TUMOR \& INITIATION OF TIL EXPANSION Patients must fulfill all of the following criteria to be eligible for the study at the time of tumor resection and initiation of TIL expansion.
  • Provision of signed and dated informed consent form.
  • Stated willingness to comply with all study procedures and availability for the duration of the study.
  • Female, aged 18 to 80 years.
  • Patients must have recurrent epithelial ovarian cancer, all subtypes will be eligible.

  • Clinical performance status of Eastern Cooperative Oncology Group (ECOG) 0 to 1 and life expectancy of > 6 months.
  • Patients must have progressed on at least one prior standard of care treatment regimen for metastatic disease, may include platinum sensitive and resistant patients. Platinum sensitive disease as defined by recurrence of disease more than 6 months following a complete response to initial treatment and platinum recurrent as defined by recurrence less than 6 months after a complete response to initial treatment. If patients are 2nd line platinum sensitive, they must have progressed < 1 year of last platinum therapy. Also, for 2nd line platinum sensitive patients that are candidates for PARP maintenance, they must have had a frontline PARP maintenance or attempt at PARP maintenance with unacceptable toxicity/intolerance. For 3rd line or more platinum sensitive patients, all platinum free intervals (PFI) are acceptable.
  • The allowance of platinum sensitive patients is based on the high response rate and durability (Sensitive: ORR-60% DOR-11.5 mos, vs Resistant: ORR 43.3, DOR 5.5 mos) seen in the study that gave rationale for the consolidative regimen of oral cyclophosphamide, bevacizumab, pembrolizumab (Zsiros et al, 2021). As well, higher responses are observed to targeted therapies in platinum sensitive patients (mirvetuximab Plat Sens: ORR 51% vs Plat resistant: 32%), similar to platinum combination response rates and PFS. By introducing an immunotherapeutic-targeted regimen in platinum sensitive patients, it further extends the platinum free interval (PFI) increasing later platinum response potential, especially those in the 6-12 mos PFI.
  • A negative pregnancy test (urine or serum) must be documented at screening for women of childbearing potential.
  • A MUGA/ECHO scan (ejection fraction > 45% is required) ≤ 6 months prior to lymphodepletion. New York Heart Association functional classification Class <1 are required.
  • Patients who have a history of ischemic heart disease, angina, or clinically significant atrial and/or ventricular arrhythmias must undergo a cardiac stress test, patients with abnormal cardiac stress test, may be considered for study if they have adequate ejection fraction (>45%) and cardiology clearance with approval of Primary Investigator.
  • Screening Pulmonary function tests should be performed for select patients (see below) with postbronchodilator values: Forced expiratory volume in 1s, (FEV1)/forced vital capacity>70%' or FEV1>50% of predicted normal is recommended.
  • History of cigarette smoking of ≥ 20 pack-years
  • Cessation of smoking withing past 2 years or still smoking
  • History of pneumonitis (including related to prior cancer treatment), COPD, or asthma
  • Significant signs of respiratory dysfunction on exam (wheezing, rales, chronic cough)
  • History of pleural drainage in the past 3 months
  • For patients with pleural effusions, if parameters are not met, consideration of drainage prior repeat PFT is reasonable, in this scenario, if reaccumulated on baseline CT after tumor procurement, consider drainage again prior to lymphodepletion.
  • Adequate renal function, including creatinine ≤ 1.5 mg/dL and CrCl >40L/min, ideally >60L/min. If creatinine is 1.6-2 mg/dL, then will need CrCl>60L/min to be considered.
  • Adequate hepatic function total bilirubin ≤ 2.0 mg/dL, except in patients with Gilbert's Syndrome who must have a total bilirubin less than 3.0 mg/dL, AST and ALT of less than 3 X institutional upper limit of normal (ULN), patients with liver metastasis may have up to 5xULN.
  • Adequate hematologic function, hemoglobin (hgb) of 8 gm/dL or more, and platelets of 75,000 per mm3 or more for surgical resection. A packed red blood cell transfusion is acceptable, though must remain stable above 8mg/dL on repeat evaluation remains stable on or after 7 days.
  • Patients must have a positive screening EBV antibody titer on screening test.
  • Participants may have had prior bevacizumab, cyclophosphamide, and/or pembrolizumab.
  • 5.1.2 STEP 2: CHEMOTHERAPY/CELL INFUSION INCLUSION CRITERIA
  • To be eligible for chemotherapy/cell infusion, patients must fulfil the following criteria:
  • Patients must have adequate TILs expanded, (>1x109 cells).
  • Women of childbearing potential (WOCBP) must practice birth control while on regimen and for 3 months after receiving the preparative regimen.
  • Unless surgically sterile by bilateral tubal ligation or vasectomy of partner(s), the patient agrees to continue to use a method of contraception throughout the study and for 90 days after your last treatment such as: barrier (i.e. condom, diaphragm), hormonal, IUD, or sponge plus spermicide.
  • For women who have menstruated within the past 12 months and have not had a surgical procedure to accomplish sterilization, pregnancy testing (serum) will be performed within 7 days prior to treatment.
  • Clinical performance status of ECOG 0 to 1 at the time of chemotherapy infusion.
  • Absolute neutrophil count greater than or equal to 1000/mm3.
  • Platelet count greater than or equal to 100,000/mm3.

About this study

Official title: OVAFIT-TIL: A Phase Ib Study of Autologous, Metabolically Optimized, CD137+ Tumor-Infiltrating Lymphocytes Followed by Consolidative Oral Cyclophosphamide, Bevacizumab, and Pembrolizumab in Recurrent Ovarian Cancer

Patients with recurrent ovarian cancer will undergo resection of a safely accessible metastatic lesion, from which tumor-infiltrating lymphocytes (TIL) will be cultured, metabolically reprogrammed for metabolic fit T cells, then selected for CD137+ activated T cells, and then expanded. This expanded TIL product will be infused following nonmyeloablative lymphodepletion chemotherapy. High-dose IL-2 will be given after TIL infusion to support the cell product expansion. Once recovered from TIL infusion, patients will start consolidative systemic therapy with oral cyclophosphamide, bevacizumab, and pembrolizumab.

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Fludarabine and Cyclophosphamide in people with Ovarian Cancer, run by Medical University of South Carolina at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 38 inclusion and 16 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: opening soon, as of the sponsor's last update on 22 Jul 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

Contact HCC Clinical Trials Office (843-792-9321, hcc-clinical-trials@musc.edu), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Dose-limiting toxicity (DLT) incidence (time frame: 12 months). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT07720180.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 22 Jul 2026.
