Study Summary

Background: A new cancer therapy takes white blood cells from a person, grows them in a lab, genetically changes them, then gives them back to the person. Researchers think this may help attack tumors in people with certain cancers. It is called gene transfer using anti-Kirsten rat sarcoma virus (KRAS) Glycine(G) to Aspartic Acid(D) substitution at codon 12(G12D) murine T-cell receptor (mTCR) cells. Objective: To see if anti-KRAS G12D mTCR cells are safe and cause tumors to shrink. Eligibility: Adults ages 18-72 who have cancer with a molecule on the tumors that can be recognized by the study cells Design: Participants will be screened with medical history, physical exam, scans, photography, and heart, lung, and lab tests. An intravenous (IV) catheter will be placed in a large vein in the chest. Participants will have leukapheresis. Blood will be removed through a needle in an arm. A machine will divide the blood and collect white blood cells. The rest of the blood will be returned to the participant through a needle in the other arm. A few weeks later, participants will have a hospital stay. They will: * Get 2 chemotherapy medicines by IV over 5 days. * Get the changed cells through the catheter. Get up to 9 doses of medicine to help the cells. They may get a shot to stimulate blood cells. * Recover in the hospital for up to 3 weeks. They will provide blood samples. Participants will take an antibiotic for at least 6 months. Participants will have several follow-up visits over 2 years. They will repeat most of the screening tests and may have leukapheresis. Participants blood will be collected for several years.

Primary Outcome

All participants will be evaluable for toxicity from the time of their first treatment with cyclophosphamide. Toxicity was assessed by the Common Terminology Criteria for Adverse Events (CTCAE v5.0). A non-serious adverse event is any untoward medical occurrence. A serious adverse event is an adverse event or suspected adverse reaction that results in death, a life-threatening adverse drug experience, hospitalization, disruption of the ability to conduct normal life functions, congenital anomaly
