Filter by:Background: Chronic lymphocytic leukemia (CLL) and small lymphocytic lymphoma (SLL) are blood cancers that affect certain white blood cells. Advanced forms of these diseases are difficult to treat. CD19 is a protein often found on the surfaces of these cancer cells. Researchers can modify a person's own immune cells (T cells) to target CD19. When these modified T cells are returned to the body-a treatment called anti-CD19 chimeric antigen receptor (CAR) T cell therapy-they may help kill cancer cells. Objective: To test anti-CD19 CAR T cell therapy in people with CLL or SLL. Eligibility: People aged 18 years and older with CLL or SLL that has not been controlled with standard drugs. Design: Participants will be screened. They will have imaging scans and tests of their heart function. If a sample of tissue from their tumor is not available, a new one may be taken; the sample will be tested for CD19. Participants will receive a drug to reduce the leukemia cells in their blood. Then they will undergo apheresis: Blood will be taken from the body through a needle. The blood will pass through a machine that separates out the T cells. The remaining blood will be returned to the body through a different needle. The collected T cells will be gene edited to make them attack cells with CD19. Participants will take drugs to prepare them for treatment for 3 days. These drugs will start 5 days before the treatment. Then their own modified CAR T cells will be returned to their bloodstream. Participants will stay in the hospital for at least 9 days after the treatment. Follow-up visits will continue for 5 years.
This study is for patients that have lymph gland disease called Hodgkin or non-Hodgkin Lymphoma or T/NK-lymphoproliferative disease and the patients condition has come back or has not gone away after treatment, including the best treatment we know for these diseases. Some patients with Lymphoma or T/NK-lymphoproliferative disease show signs of virus that is sometimes called Epstein Barr virus (EBV). This virus causes mononucleosis or glandular fever ("mono") before or at the time of their diagnosis. EBV is found in the cancer cells of up to half the patients with Hodgkin's and non-Hodgkin Lymphoma. This suggests that the EBV plays a role in causing Lymphoma. The cancer cells (in lymphoma) and some immune system cells infected by EBV are able to hide from the body's immune system and escape destruction. T cells, also called T lymphocytes, are special infection-fighting blood cells that can kill other cells, including cells infected with viruses and tumor cells. T cells have been used to treat patients with cancers. T cells, that have been trained to kill EBV infected cells can survive in blood and affect the tumor. We have treated over 80 people on studies using T cells to target these diseases. About half of those patients who had disease at the time they got the cells had responses including some patients with complete responses (meaning the cancer could no longer be detected). We think that if T cells are able to last longer in the body, they may have a better chance of killing EBV and EBV infected tumor cells. Therefore, in this study we will add a new gene to the EBV T cells that can cause the cells to live longer called C7R. We know that T cells need substances called cytokines (substances such as proteins released by specific cells of the immune system) to survive and that the cells may not get enough cytokines after the cells are infused into the body. We have added the gene C7R that gives the cells a constant supply of cytokine and helps them to survive for a longer period of time. The purpose of this study is to find the largest safe dose of C7R-EBV T cells, and additionally to evaluate how long they can be detected in the blood and what affect they have on the cancer.
This study, a single-center, open, single-dose clinical study, was designed to evaluate the safety, tolerability, and pharmacokinetic profile of INS19 CAR-T cells for the treatment of patients with relapsed or refractory acute B lymphoblastic leukemia
This is a phase I dose-finding trial of an autologous CD22 targeting chimeric antigen receptor (CAR)-T cell product, called CLIC-2201, for participants with relapsed/refractory B cell malignancies. In the proposed trial, eligible enrolled participants will undergo leukapheresis for autologous T cell collection to enable CLIC-2201 manufacturing, followed by lymphodepletion with cyclophosphamide and fludarabine, then intravenous infusion of the autologous CLIC-2201 product. The trial will use the 3+3 design to escalate or de-escalate the dose level of CLIC-2201 administered. Participants will be monitored for safety and tolerability up to day 365 following CLIC-2201 infusion. The primary objective is to evaluate the safety and tolerability of CLIC-2201 and estimate the maximum tolerated dose (MTD) of CLIC-2201 in B-cell malignancies. The secondary objectives are to evaluate the (i) feasibility; (ii) anti-tumour activity of CLIC-2201; (iii) and characterize the pharmacokinetic (PK) profile of CLIC-2201. Exploratory objectives will include: i) characterizing the cellular and humoral immune responses against CLIC-2201 up to 1 year following infusion of CLIC-2201; (ii) characterizing the phenotype and gene expression profile of CLIC-2201 cells; (iii) evaluating immune and tumour cells at baseline and relapse for biomarkers of response or toxicity; (iv) evaluating serum cytokines, circulating tumour DNA (ctDNA) and B cell aplasia as biomarkers of clinical outcomes; and (v) assessing the quality of life.
This pilot study examines the safety and efficacy of anti-CD19 CAR T cells manufactured on-site in children and young adults with relapsed or refractory CD19+ B cell acute lymphoblastic leukemia or CD19+ B cell non Hodgkin lymphoma. Patients will undergo screening, leukapheresis (cell collection), lymphodepleting chemotherapy with fludarabine and cyclophosphamide, followed by the anti-CD19 CAR T cell infusion. The lymphodepleting chemotherapy is administered over four days IV to prepare the body for the CAR T cells. The anti-CD19 CAR-T cells are infused between 2-14 days after the last dose of chemotherapy. This study is designed for participants to begin lymphodepleting chemotherapy during the CAR T cell manufacture and receive a fresh cell infusion on the day that manufacturing is complete. Some patients may need more time in between the cell collection and the CAR T cell infusion, therefore, the cells may be manufactured and frozen prior to administration. Patients will be followed for a year after the cell infusion on the study and for up to 15 years to monitor for potential long term side effects of cell therapy.
This study aims to evaluate the safety, efficacy and duration of response of CD19 Chimeric Antigen Receptor (CAR) redirected autologous T-cells in patients with high risk, relapsed CD19+ haematological malignancies.
This study aims to evaluate the safety and clinical activity of CD19 Chimeric Antigen Receptor (CAR) redirected autologous T-cells in treating patients with recurrent or refractory CD19 positive B cell ccute lymphoblastic leukemia,and dynamically observe the changes of CAR-T in patients and the residual tumor.
This is an observational cohort study of patients with a new diagnosis of B cell Chronic Lymphocytic Leukemia or B cell Non-Hodgkin's Lymphoma who will receive an anti-CD20 monoclonal antibody treatment during the induction phase of their treatment. Throughout the study, patients will have four blood draws at specified time points throughout the study. The initial blood draw will be analysed test patients for Cytomegalovirus and conduct a g-NK cell analysis. The final three blood draws will be conducted to analyse the g-NK cells at specified time points. The objectives of this study are to: 1) characterize the frequency of CMV (+) and g-NK (+) individuals in the B-NHL and B-CLL populations, 2) Determine changes in circulating g-NK cells during and after anti-CD20 monoclonal antibody containing remission induction chemotherapy and 3) Evaluate whether the presence of g-NK cells improve the outcome of anti-CD20 monoclonal antibody containing remission induction treatment of patients with B-NHL or B-CLL.
This study is designed for determining the safety and relative engraftment levels of the redirected autologous T cells transduced with the anti-CD19 lentiviral vector in patients with CD19-positive B cell leukemia and malignant lymphoma.
