Compassionate Use of CAR T Cells Targeting the CD19 Antigen and Containing the Inducible Caspase 9 Safety Switch

Start date: n/a
Phase:
Study type: Expanded Access

This protocol for compassionate use combines 2 different ways of fighting disease: antibodies and T cells. Both antibodies and T cells have been used to treat patients with cancers, and both have shown promise, but neither alone has been sufficient to cure most patients. This protocol combines both T cells and antibodies to create a more effective treatment. The investigational treatment is called autologous T lymphocyte chimeric antigen receptor cells targeted against the CD19 antigen (ATLCAR.CD19) administration. Prior studies have shown that a new gene can be put into T cells and will increase their ability to recognize and kill cancer cells. The new gene that is put in the T cells in this study makes a piece of an antibody called anti-CD19. This antibody sticks to leukemia cells because they have a substance on the outside of the cells called CD19. For this protocol, the anti-CD19 antibody has been changed so that instead of floating free in the blood part of it is now joined to the T cells. When an antibody is joined to a T cell in this way it is called a chimeric receptor. These CD19 chimeric (combination) receptor-activated T cells seem to kill some of the tumor, but they do not last very long in the body and so their chances of fighting the cancer are unknown. Preliminary results have shown that many subjects receiving this treatment have experienced unwanted side effects including cytokine release syndrome. In this protocol, to help reduce cytokine release syndrome symptoms, the ATLCAR.CD19 cells have a safety switch that when active, can cause the cells to become dormant. These modified ATLCAR.CD19 cells with the safety switch are referred to as iC9-CAR19 cells. If the patient experiences moderate to severe cytokine release syndrome as a result of being given iC9-CAR19 cells, the patient can be given a dose of a second study drug, AP1903, if standard interventions fail to alleviate the symptoms of cytokine release syndrome. AP1903 activates the iC9-CAR19 safety switch, reducing the number of the iC9-CAR19 cells in the blood. The primary purpose of this protocol is to treat a single patient with a second dose of iC9-CAR19 T cells.

Expanded Access Protocol (EAP) Using the CliniMACS® Device for Pediatric Haplocompatible Donor Stem Cell Transplant

Start date: n/a
Phase:
Study type: Expanded Access

This protocol provides expanded access to bone marrow transplants for children who lack a histocompatible (tissue matched) stem cell or bone marrow donor when an alternative donor (unrelated donor or half-matched related donor) is available to donate. In this procedure, some of the blood forming cells (the stem cells) are collected from the blood of a partially human leukocyte antigen (HLA) matched (haploidentical) donor and are transplanted into the patient (the recipient) after administration of a "conditioning regimen". A conditioning regimen consists of chemotherapy and sometimes radiation to the entire body (total body irradiation, or TBI), which is meant to destroy the cancer cells and suppress the recipient's immune system to allow the transplanted cells to take (grow). A major problem after a transplant from an alternative donor is increased risk of Graft-versus-Host Disease (GVHD), which occurs when donor T cells (white blood cells that are involved with the body's immune response) attack other tissues or organs like the skin, liver and intestines of the transplant recipient. In this study, stem cells that are obtained from a partially-matched donor will be highly purified using the investigational CliniMACS® stem cell selection device in an effort to achieve specific T cell target values. The primary aim of the study is to help improve overall survival with haploidentical stem cell transplant in a high risk patient population by limiting the complication of GVHD.
