You likely can't join if
- Positive for HLA-A*02:05 in either allele as determined by Sponsor-designated central laboratory. HLA-A*02 alleles having the same protein sequence as HLA-A*02:05 in the peptide binding domains (P groups) will also be excluded. Other alleles may be exclusionary after adjudication with the Sponsor.
- Subject has received or plans to receive the following therapy/treatment prior to leukapheresis or lymphodepleting chemotherapy, unless stopped according to the washout requirements: Note: The washout periods are provided as a guideline in the table below. For Spain only, minor modifications to washout periods, if assessed as not clinically significant by the site study Investigator or designee, may be acceptable after discussing with the Sponsor Study Physician. (for full details please refer to section 5.3 of the study protocol (Exclusion Criteria 2. )
- Toxicity from previous anti-cancer therapy that has not recovered to Grade ≤ 1 or baseline prior to enrollment (except for nonclinically significant toxicities, e.g., alopecia and vitiligo). Subjects with Grade 2 toxicities that are deemed stable or irreversible (e.g., peripheral neuropathy) can be enrolled.
- Subject has a history of allergic reactions attributed to compounds of similar chemical or biologic composition to fludarabine, cyclophosphamide, or other agents used in the study.
- Subject has an active autoimmune or immune-mediated disease that has not yet resolved. Subjects with immune-mediated AEs secondary to treatment with immunotherapy that resolve to Grade ≤ 1 off steroids are permitted. Subjects with hypothyroidism, type I diabetes, adrenal insufficiency, or pituitary insufficiency that are stable on replacement therapy are eligible. Subjects with disorders such as asthma, vitiligo, psoriasis, or atopic dermatitis that are well controlled without requiring systemic immunosuppression are also eligible. Other stable immune conditions that do not require prednisone > 20 mg/day (or its equivalent for other corticosteroid agents) may be acceptable with the agreement of the Sponsor.
- Subject had major surgery within 4 weeks prior to lymphodepletion; subjects should have been fully recovere from any surgical-related toxicities. Surgical-related toxicities which are not clinically significant per Investigator assessment may be acceptable after discussion and agreement with Study Physician.

- Subject is ≥ 18 and ≤ 75 years of age at the time the Pre-Screening informed consent form (ICF) is signed.
- Subject has histologically confirmed diagnosis of high-grade serous or high-grade endometrioid recurrent ovarian carcinoma, including primary peritoneal and fallopian tube carcinoma.
- Subject has measurable disease according to RECIST v1.1 prior to lymphodepletion. Measurable disease is not required prior to leukapheresis.
- Subject has the following disease-specific prior therapy requirements: a. The initial therapy must have included at least 3 cycles of a prior platinum and taxane based chemotherapy regimen for primary disease, possibly including intraperitoneal therapy, consolidation, or extended therapy (maintenance/consolidation). b. Subjects may receive up to 4 prior regimens of combination or single agent systemic treatment for their disease, which may include investigational therapies unless discussed and agreed upon with the Sponsor or designee. Note: Neo-adjuvant/adjuvant treatment is considered as one line of treatment. Bridging therapy is permitted and is not considered as a line of treatment. c. Subjects who have received only 1 line of platinum based therapy must have progressed between 93 and 183 days of completing platinum based therapy as a part of front line treatment of ovarian cancer. Subjects who have progressed within 92 days of completing platinum based therapy in front line treatment are excluded. d. Subjects who have received 2 or more lines of platinum based therapy must have progressed during or within 183 days of completing the latest platinum based therapy for treatment of recurrent ovarian cancer. The number of days (platinum free interval) should be calculated from the date of the last administered dose of platinum therapy to the date of documentation of progression. e. Subjects with a known BRCA mutation (germ line or somatic) must have received a poly adenosine diphosphate-ribose polymerase inhibitor (PARPi). f. Subjects must have received bevacizumab.
- Positive for HLA-A*02:01, HLA-A*02:02, HLA-A*02:03, or HLA- A*02:06 allele as determined by Sponsor-designated central laboratory testing. HLA-A*02 alleles having the same protein sequence in the peptide binding domains (P group) will also be included. Other HLA-A*02 alleles may be eligible after adjudication with the Sponsor.
- MAGE-A4 expression, defined as ≥ 30% of tumor cells that are ≥ 2+ by IHC, should be documented at the pre-screening period based on either an archival specimen or a fresh biopsy. All samples must have been pathologically reviewed by an Sponsor designated central laboratory confirming expression.
- Subject has an Eastern Cooperative Oncology Group (ECOG) performance status (PS) of 0 or 1

Subjects who have asymptomatic CNS metastases without associated edema, shift, or requirement for steroids or antiseizure medications are eligible. If such a subject receives SRS or WBRT, a minimum period of 2 weeks needs to lapse between the therapy and lymphodepletion. Prophylactic anti- seizure medication is allowed.
