2. Prior allogeneic stem cell transplant.
3. Prior solid organ transplant.

Part 2 : Key Inclusion Criteria

Pathologically confirmed solid tumors, e.g., Colorectal Cancer (CRC), Non-Small Cell Lung Cancer (NSCLC), Pancreatic Cancer (PANC), Mesothelioma, or Ovarian Cancer (OVAC) that is metastatic, unresectable locally advanced, or in the Investigator's opinion the subject is high risk for incurable relapse within two years.
2. Participants are germline HLA-A\*02 heterozygous confirmed by HLA typing.
3. Primary tumor tissue showing LOH of HLA-A\*02 by NGS testing.

Part 2: Key Exclusion Criteria

1. History of any of other malignancy in the past 5 years other than non-melanoma skin carcinoma, low grade localized prostate cancer, superficial bladder cancer, ductal carcinoma in situ (CIS) of the breast, CIS of the Cervix, or Stage I uterine cancer.
2. Prior allogeneic stem cell transplant.
3. Prior solid organ transplant.
4. Participants who have received any cancer therapy on any investigational therapy for any indication, including but not limited to chemotherapy, small molecules, monoclonal antibodies, or radiotherapy (with bone marrow impact) within 2 weeks of planned apheresis or 3 half-lives, whichever is shorter.
5. Known active bacterial, viral, fungal, mycobacterial, parasitic, or other infection (excluding fungal infections of nail beds) at study enrollment necessitating specific treatment, or any major episode of infection requiring treatment with Intravenous (IV) antimicrobials (e.g., IV antibiotics) or hospitalization (relating to completion of antibiotic course).
6. Has known active central nervous system metastases. Subjects with previously treated brain metastases may participate upon medical monitor agreement.
7. In the Investigator's judgement, any other condition or reason the subject would not complete the required study visits and procedures, and follow up visits, or comply with the study requirements for participation.
