Who this trial is looking for
This trial is looking for adults with certain types of solid tumors that express mesothelin and have lost HLA-A*02 expression. Participants will receive a special treatment called Tmod CAR T-cell therapy after undergoing some health assessments and procedures.

You may be able to join if
I have a solid tumor like colorectal, pancreatic, or lung cancer.
I have been part of a specific study called BASECAMP-1.
My tumor has certain markers needed for this trial.
I have measurable disease that is not treatable by surgery.
I have enough healthy cells collected for the treatment.
I have a life expectancy of at least 3 months.
I agree to follow the study schedule for assessments.
I am able to meet the health requirements detailed in the study.
You may not be able to join if
I have a heart condition that has been unstable in the last 6 months.
I have had a cancer treatment within the last 3 weeks.
I have received radiation therapy in the last 28 days.
I have a history of certain blood clots in the last 3 months.
I need home oxygen to breathe.
I am pregnant or breastfeeding.
I am not willing to use birth control if I could get pregnant.

The goal of this study is to test autologous logic-gated Tmod™ CAR T-cell products in subjects with solid tumors including colorectal cancer (CRC), pancreatic cancer (PANC), non-small cell lung cancer (NSCLC), ovarian cancer (OVCA), mesothelioma (MESO), and other solid tumors that express mesothelin (MSLN) and have lost HLA-A\*02 expression.
The main questions this study aims to answer are:

The main questions this study aims to answer are:
Phase 1: What is the recommended dose that is safe for patients
Phase 2: Does the recommended dose kill solid tumor cells and protect the patient's healthy cells
Participants will be required to perform study procedures and assessments, and will also receive the following study treatments:
Enrollment and Apheresis in BASECAMP-1 (NCT04981119)
Preconditioning Lymphodepletion (PCLD) Regimen
Tmod CAR T cells at the assigned dose

2. Prior allogeneic stem cell transplant
3. Prior solid organ transplant
4. MESO with pleural involvement extending into the peritoneum
5. Cancer therapy within 3 weeks or 3 half lives of infusion
