To learn about the relationship between changes in pupil size and reactivity and the start of neurological side effects in patients after receiving CAR-T cell therapy.
Changing the schedule of intrathecal chemotherapy to be given before and during blinatumomab will maintain the anti-leukemic effects of this drug while at the same time adding the benefit of limiting the neurotoxicity associated with cytokine release.
Background: CAR T-cell therapy is a promising new treatment for blood cancers. During treatment, a person s T-cells are genetically changed to kill cancer cells. Researchers want to learn more about the effects of potential problems that may be associated with this treatment. We are specifically interested in learning if and how this treatment may affect the brain or your thinking skills. Objective: To learn if CAR T-cell therapy can affect how children and adults think, process, and remember things. Eligibility: People aged 5-35 who have blood cancer that has not responded to treatment, or the blood cancer has come back after treatment, and who will receive CAR T-cell therapy. Caregivers are also needed. All participants must be able to speak and read in English or Spanish. Design: Participants will be screened with a medical history. Information from participants medical records will be collected. Participants will take tests at home or at NIH to see how well they think, read, learn, remember, reason, and pay attention. The tests will be both computerized and paper/pencil. They will take less than 1 hour to complete. Participants and a parent/adult observer will complete a 5-minute Background Information Form and a checklist of nervous system symptoms. If participants are 5 years or older, they will participate in activities to test their ability to do different thinking tasks, like answer questions, complete puzzle patterns, and remember things. Participants and their caregivers will complete questions to see if they are having specific symptoms related to receiving CAR T-cells. The questions will assess their well-being and needs. The questions will take less than 1 hour to complete. Some tests and questions will be repeated at different time points in the study. Participation will last for up to 3 years.
This study will address whether cannabis affects antiretroviral therapy (ART) drug concentrations, mood, and thinking. The project will have two phases. Phase 1 is an observational study, in which 120 people will be assessed to evaluate the effects of chronic cannabis use on ART drug concentrations, mood, and thinking. In Phase 2, the study will administer cannabis (or placebo) to 40 people to examine its acute effects on ART drug concentrations.
This research study 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 study combines both T cells and antibodies to create a more effective treatment. The treatment being researched 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 study, 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 subjects receiving this treatment have experienced unwanted side effects including cytokine release syndrome and neurotoxicity. In this study, to help reduce cytokine release syndrome and/or neurotoxicity 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 subject experiences moderate to severe cytokine release syndrome and or neurotoxicity as a result of being given iC9-CAR19 cells, the subject can be given a dose of a second study drug, AP1903, if standard interventions fail to alleviate the symptoms of cytokine release syndrome and/or neurotoxicity. AP1903 activates the iC9-CAR19 safety switch, reducing the number of the iC9-CAR19 cells in the blood. The ultimate goal is to determine what dose of AP1903 can be given that reduces the severity of the cytokine release syndrome and/or neurotoxicity, but still allows the remaining iC9-CAR19 cells to effectively fight the lymphoma. The primary purpose of this study is to determine whether receiving iC9-CAR19 cells is safe and tolerable in patients with relapsed/refractory B-cell lymphoma, primary central nervous system lymphoma and chronic lymphocytic leukemia (CLL)/small lymphocytic lymphoma (SLL).
This is a phase II study to evaluate the outpatient administration of Teclistamab or Talquetamab in Multiple Myeloma patients
The body has different ways of fighting infection and disease. No single way is effective at fighting cancer. This research study combines two different ways of fighting disease: antibodies and T cells. Antibodies are proteins that protect the body from disease caused by bacteria or toxic substances. Antibodies work by binding those bacteria or substances, which stops them from growing and causing bad effects. T cells, also called T lymphocytes, are special infection-fighting blood cells that can kill other cells, including tumor cells or cells that are infected. Both antibodies and T cells have been used to treat patients with cancers. They both have shown promise, but neither alone has been sufficient to cure most patients. This study combines both T cells and antibodies to try to create a more effective treatment. This investigational treatment is called autologous T lymphocyte chimeric antigen receptor cells targeted against the CD19 antigen (ATLCAR.CD19) administration. In previous studies, it has been shown that a new gene can be put into T cells that will increase their ability to recognize and kill cancer cells. A gene is a unit of DNA. Genes make up the chemical structure carrying the genetic information that may determine human characteristics (i.e., eye color, height and sex). The new gene that is put in the T cells makes a piece of an antibody called anti-CD19. This antibody can flow through the blood and can find and stick to leukemia cells because these leukemia cells have a substance on their surface called CD19. Anti-CD19 antibodies have been used to treat people with leukemia but have not been strong enough to cure most patients. For this study, the anti-CD19 antibody has been changed so that instead of floating free in the blood a piece of it is now joined to the surface of the T cells. Only the part of the antibody that sticks to the leukemia cells is attached to the T cells instead of the entire antibody. 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 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 of giving ATLCAR.CD19 cells to leukemia patients have been encouraging; however, many subjects receiving this treatment have experienced unwanted side effects including neurotoxicity and/or cytokine release syndrome (also referred to as cytokine storm or an infusion reaction). Cytokines are small proteins that interreact as e signals to other cells and are the way cells talk to one another. During cytokine release syndrome, too many cytokines are released and too many cells in your body react to their release. Symptoms resulting from cytokine release syndrome vary from flu-like symptoms to more severe side effects such as cardiac arrest, multi-system organ failure or death. We predict that about 50% of patients on this study will experience mild to severe cytokine release syndrome. To help reduce cytokine release syndrome symptoms in future patients, a safety switch has been added to the ATLCAR.CD19 cells that can cause the cells to become dormant or "go to sleep". The safety switch is called inducible caspase 9 or iC9. The modified ATLCAR.CD19 cells with the safety switch are referred to as iC9-CAR19 cells. The purpose of this study is to determine whether receiving the iC9-CAR19 cells is safe and tolerable (there are not too many unwanted effects). Researchers has previously tested different doses of the iC9-CAR19. An effective dose that had the least number of unwanted side effects in patients was identified. It was planned to test this dose in more patients to learn more about its effect in the body. This type of research study is called a dose expansion study. It will allow the investigators to collect more information about the effect of this dose in treating of certain type of cancer.
