Administering Peripheral Blood Lymphocytes Transduced With a Murine T-Cell Receptor Recognizing the G12V Variant of Mutated RAS in HLA-A*11:01 Patients
A Phase I/II Study Administering Peripheral Blood Lymphocytes Transduced With a Murine T-Cell Receptor Recognizing the G12V Variant of Mutated RAS in HLA-A*11:01 Patients
About This Trial
Background: A new cancer therapy involves taking white blood cells from a person, growing them in the lab, genetically modifying them, then giving them back to the person. This therapy is called gene transfer using anti-KRAS G12V mTCR cells. Objective: To see if anti-KRAS G12 V mTCR cells are safe and can shrink tumors. Eligibility: Adults at least 18 years old with cancer that has the KRAS G12V molecule on the surface of tumors. Design: In another protocol, participants will: Be screened Have cells harvested and grown Have leukapheresis In this protocol, participants will have the procedures below. Participants will be admitted to the hospital. Over 5 days, participants will get 2 chemotherapy medicines as an infusion via catheter in the upper chest. A few days later, participants will get the anti-KRAS G12V mTCR cells via catheter. For up to 3 days, participants will get a drug to make the cells active. A day after getting the cells, participants will get a drug to increase their white blood cell count. This will be a shot or injection under the skin. Participants will recover in the hospital for 1-2 weeks. They will have lab and blood tests. Participants will take an antibiotic for at least 6 months. Participants will have visits every few months for 2 years, and then as determined by their doctor. Visits will be 1-2 days. They will include lab tests, imaging studies, and physical exam. Some visits may include leukapheresis or blood drawn. Participants will have blood collected over several years.
