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.

Interventions

DRUG

Cyclophosphamide

Days -7 and -6: Cyclophosphamide 60 mg/kg/day x 2 days intravenous (IV) in 250 mL 5% Dextrose in water (D5W) infused simultaneously with mesna 15 mg/kg/day over 1 hour x 2 days.

DRUG

Fludarabine

Days -7 to -3: Fludarabine 25 mg/m\^2/day intravenous piggyback (IVPB) daily over 30 minutes for 5 days.

DRUG

Aldesleukin

Aldesleukin 720,000 IU/kg intravenous (IV) (based on total body weight) over 15 minutes approximately every 8 hours beginning within 24 hours of cell infusion and continuing for up to 3 days (maximum 9 doses).

BIOLOGICAL

anti-Kirsten rat sarcoma virus (KRAS) Glycine(G) to Aspartic Acid(D) substitution at codon 12 peripheral blood lymphocytes (PBL)

Day 0: Cells will be infused intravenously on the Patient Care Unit over 20-30 minutes (2-4 days after the last dose of fludarabine).
