TRAIL-R2 and HER2 Bi-Specific Chimeric Antigen Receptor (CAR) T Cells for the Treatment of Metastatic Breast Cancer : (TRAILBLASER) TRAIL-R2 and HER2 Bi-Specific Chimeric Antigen Receptor T Cells for the Treatment of Metastatic Breast Cancer
To make the T cells, the investigators will take the patient's blood and stimulate it with growth factors to make T cells grow. Investigators use a retrovirus to insert HER CAR, TR2 antibody and IL 15 genes into the T cells.HTR2 cells are generated from the patient's T cells and are frozen. At the time the patient is scheduled to be treated, the cells will then be thawed and injected into the patient over 5 to 10 minutes. Patients will only get one dose of HTR2 T cells during the infusion. If the patient has a good response and tolerance, we may be able to repeat infusion in the future. The patent may be pretreated with Tylenol and Benadryl to prevent possible allergic reaction to the T cell administration.If investigators need to stop the HTR2 T cells due to bad side effects, investigators have inserted a gene called iCasp9 into the T cells. This allows investigators to eliminate the HTR2 T cells in the blood when the gene comes into contact with a medication called Rimiducid. The drug Rimiducid is not yet FDA approved and is an experimental drug, but it has been tested in humans without bad side-effects. Investigators will only use this drug to kill the T cells if necessary due to side effects. Since investigators do not know exactly what dose will effectively stop HTR2 T cells in individual patients, investigators will start at a low dose with the ability to increase the dose two more times based on how patients are doing. Blood work will be done to ensure that the HTR2 T cells have been successfully eliminated.The treatment will be given by the Center for Cell and Gene Therapy at Houston Methodist Hospital.MEDICAL TESTS BEFORE TREATMENTBefore being treated, patients will receive a series of standard medical tests:Physical exam and historyBlood tests to measure blood cells and organ functionMeasurements of the tumor by scans at baseline prior to treatmentUltrasound of the heart to make sure the patient has good baseline cardiac functionAdditionally, patients will need a biopsy of their tumor tissue to both confirm HER2 expression and to be used for research purposes.MEDICAL TESTS DURING AND AFTER TREATMENTWithin four weeks after infusion, patients will be monitored on a weekly basis for dose limiting side effects of the HTR2 T cells:Physical exam and historyBlood tests to measure blood cells and organ functionAfter the initial six weeks, patients will be monitored at a minimum every 3 months for the 1st year and every 6 months between 1 to year 5 or as frequently as deemed necessary:Physical exam and historyBlood tests to measure blood cells and organ functionMeasurements of patient's tumor by scans to assess treatment responseTo learn more about the way T cells work in the patient's body, investigators will obtain up to 50 ml of blood from patient before chemotherapy, before the T-cell infusion, 1 to 4 hours, 1, 2, 3, 4 weeks and 8 weeks after infusion, every 3 months for a year followed by every 6 months for 4 years and then every year for the the next 10 years. Total participation on this study will be 15 years. During the time points listed above, if the T cells are found in the blood at a certain amount, an extra half a tablespoon of blood may be needed for additional testing.Investigators will obtain one tissue biopsy within 4 weeks after infusion and as clinically indicated thereafter. If additional clinically indicated tumor biopsies are obtained, investigators will ask for a portion of the sample for research..
