Study of TROP2 CAR Engineered IL15-transduced Cord Blood-derived NK Cells Delivered Intraperitoneally for the Management of Platinum Resistant Ovarian Cancer, Mesonephric-like Adenocarcinoma, and Pancreatic Cancer

1. Pregnant, breastfeeding, or expecting to conceive within the projected duration of the study, starting with the screening visit through 3 months after the last dose of trial treatment.

If a WOCBP has a positive urine pregnancy test within 72 hours prior to hospital admission that cannot be confirmed as negative, a serum pregnancy test will be required (see Appendix 1).

2. Has received systemic anti-cancer therapy including investigational agents within 4 weeks of starting lymphodepleting chemotherapy.

3. Participants must have recovered from all AEs due to previous therapies to ≤ Grade 1 or baseline.

Participants with ≤ Grade 2 neuropathy, alopecia, or other non-relevant AEs may be deemed eligible at the discretion of the PI. If a participant received major surgery, they must have recovered adequately from the toxicity and/or complications from the intervention prior to starting study treatment.

4. Has received prior radiotherapy within 2 weeks of start of study intervention. Participants must have recovered from all radiation-related toxicities, not require corticosteroids, and not have had radiation pneumonitis. A 1-week washout is permitted for palliative radiation (≤2 weeks of radiotherapy) to non-central nervous system (CNS) disease.

5. Has received a live vaccine within 30 days prior to the first dose of study drug. Examples of live vaccines include, but are not limited to, the following: measles, mumps, rubella, varicella/zoster (chicken pox), yellow fever, rabies, Bacillus Calmette-Guérin (BCG), and typhoid vaccine.

Seasonal influenza vaccines for injection are generally killed virus vaccines and are allowed; However, intranasal influenza vaccines (e.g., FluMist®) are live attenuated vaccines and are not allowed.

6. Is currently receiving another investigational agent or has used an investigational device within 4 weeks prior to the first dose of study intervention. Participants who have entered the follow-up phase of an investigational study may participate as long as it has been 4 weeks after the last dose of the previous investigational agent.

7. Diagnosis of immunodeficiency or receiving chronic systemic steroid therapy (in dosing exceeding 10 mg daily of prednisone equivalent) or any other form of immunosuppressive therapy within 7 days prior to the first dose of study drug.

8. History of a second malignancy, unless potentially curative treatment has been completed with no evidence of malignancy for 2 years. The time requirement does not apply to participants who underwent successful definitive resection of basal cell carcinoma of the skin, squamous cell carcinoma of the skin, superficial bladder cancer, in situ cervical cancer, or other in-situ cancers.

9. Known active CNS metastases and/or carcinomatous meningitis. Participants with previously treated brain metastases may participate provided they are radiologically stable, i.e. without evidence of progression for at least 4 weeks by repeat imaging (note that the repeat imaging should be performed during study screening), clinically stable and without requirement of steroid treatment for at least 14 days prior to first dose of study intervention.

10. Active autoimmune disease that has required systemic treatment in the past 2 years (i.e. with use of disease modifying agents, corticosteroids or immunosuppressive drugs). Replacement therapy (e.g., thyroxine, insulin, or physiologic corticosteroid replacement therapy for adrenal or pituitary insufficiency, etc.) is allowed.

11. History of interstitial lung disease that required steroids or has current pneumonitis/interstitial lung disease.

12. Active infection requiring systemic therapy.

13. Known history of uncontrolled Human Immunodeficiency Virus (HIV) infection. Patients with HIV infection and undetectable viral load may participate.

14. Known history of chronic Hepatitis B or Hepatitis C virus infection.

15. Known history of active TB (Bacillus Tuberculosis).

16. History or current evidence of any condition, therapy, or laboratory abnormality that might confound the results of the study, interfere with the subject's participation for the full duration of the study, or is not in the best interest of the subject to participate, in the opinion of the treating investigator.

17. Known psychiatric or substance abuse disorders that would interfere with cooperation with the requirements of the trial.

18. Has had an allogenic tissue/solid organ transplant.

19. Clinically significant cardiovascular disease within 12 months from first dose of study intervention, including New York Heart Association (NYHA) Class III or IV congestive heart failure, unstable angina, myocardial infarction, cerebral vascular event, or cardiac arrhythmia associated with hemodynamic instability. Note: medically controlled arrhythmia would be permitted.

20. Prolongation of QTcF interval to \>480 ms

21. Bleeding or thrombotic disorders or subjects at risk for severe hemorrhage. Subject with known deep vein thrombosis/pulmonary embolism that are under appropriate anti-coagulation treatment are eligible.

22. Radiographic evidence of tumor encasement or invasion of a major blood vessel, or intra-tumoral cavitation.

23. Active peritonitis or diverticulitis

24. Medical or surgical history that in the treating physician's opinion would make the subjective not a suitable candidate for intraperitoneal therapy. Examples would include surgically documented extensive intraperitoneal adhesions or large volume ascites.

25. History of severe hypersensitivity reaction with biologic therapy (e.g. monoclonal antibodies)
