Filter by:This is a prospective, single-center, single-arm clinical study to evaluate the efficacy and safety of maintenance therapy with obinutuzumab for 2 years in patients ≥ 18 years of age with newly diagnosed mature B-cell lymphoma (including follicular lymphoma[FL], marginal zone cell lymphoma[MZL] , waldenström macroglobulinemia[WM], hairy-cell leukemia variant[HCL-v]) who achieved ≥ PR after 6 cycles of obinutuzumab in combination with bendamustine.
The purpose of the study is to establish the safety and efficacy of zanubrutinib in combination with rituximab for people with untreated B-cell lymphomas (marginal zone lymphoma and follicular lymphomas).
CAR-T cell therapy is a type of treatment for people with certain lymphomas. T-cells are white blood cells that help to fight infections. CAR-T cell therapy improves the body's T-cells to help them better fight cancer cells. ASP2802 is a type of CAR-T cell therapy given with MA-20. MA-20 is a protein that helps the CAR-T cell therapy work inside the body. Before ASP2802 is available as a treatment, the researchers need to understand how it is processed by and acts upon the body. This information will help find a suitable dose for future studies and check for potential medical problems from the treatment. In this study, ASP2802 is being tested in humans for the first time. ASP2802 has already been tested in the laboratory and in animals. This is the standard way new potential treatments are developed. People taking part in this study will be adults with CD20-positive B-cell lymphomas. CD20 is a protein found on a type of white blood cell called a B-cell. Some people with B-cell lymphomas have more CD20 on these cells. Their cancer will have come back after it had disappeared with earlier therapy (relapsed) or it will have become resistant to previous treatment (refractory). The main aims of the study are to check the safety of ASP2802, how well it is tolerated, and to find a suitable dose of ASP2802. This is an open-label, adaptive study. Open-label means that people in this study and clinic staff will know that people will receive ASP2802 treatment. Adaptive means the treatments may change, depending on earlier results in the study. There will be 3 groups of people in this study and 3 doses of ASP2802. Groups A, B and C will receive ASP2802 treatment. Group A will start treatment first with a low dose of ASP2802. If Group A tolerates the low dose of ASP2802, then Group B will receive the higher dose of ASP2802. If Group B tolerates the higher dose of ASP2802, then Group C will receive the highest dose of ASP2802. There are several steps in this treatment. First, T-cells are removed from the blood by inserting a small tube (cannula) into a vein and connecting it to a machine that separates out the blood cells. The machine collects the T-cells and returns the rest of the blood cells back into the bloodstream. The collected T-cells are sent to the lab to be changed into improved T-cells (with ASP2802) to fight the cancer. This may take several weeks, so people in the study may receive extra treatment, to keep the cancer under control during this time. Before the improved T-cells go back in the body, people will visit the clinic so that the study doctors can do a series of checks to make sure they are well enough to receive the T-cells. A few days before the improved T-cells go back into the body, people in the study will have chemotherapy for 3 days. This is to make sure the cancer is at its lowest level before people are treated with ASP2802. Then, the improved T-cells are fed back into the bloodstream using a drip attached to the cannula. After this, a booster of MA-20 will be given at the set dose by infusion on Day 3 and Day 17 in a 28-day cycle. If people respond well to treatment, they may stay on the same dose during the next cycle; if they have medical problems from the treatment, they may get a lower dose during the next cycle. The next group of people may receive a different dose (higher or lower) of MA-20 depending on the results from the previous group. People in the study will continue receiving MA-20 in this way until: they have certain medical problems from the treatment on the lowest dose of MA-20; they start other cancer treatment; their cancer gets worse; they or the study doctor decides they should stop treatment; they do not come back for treatment. After treatment has finished, people in the study will visit the clinic regularly for 2 years and continue to be monitored for up to 15 years. Some people may be treated again with MA-20. This may happen for people who have responded to treatment and then relapse within a year, or for people that have a partial response and have a slow growing lymphoma. During the study, people will visit the study hospital many times. During most visits, the study doctors will do a medical examination, blood tests and check vital signs. Vital signs include temperature, breathing rate, blood pressure, blood oxygen levels, and heart rate. They will also check for medical problems. In some visits, computerized tomography (CT) scans and electrocardiograms (ECGs) to check the heart rhythm will also be done. People will have several hospital stays during their treatment. This may be during their chemotherapy, then from Days -1 to 7 and Days 17 to 21 during the cycle 1 of MA-20. Day -1 means 1 day before treatment with ASP2802. During this time, people will be closely monitored for medical problems, have EGCs and have a biopsy taken. During the extra cycles of MA-20, there will be the option of staying overnight.
To learn if the combination of axicabtagene ciloleucel (axi-cel) and glofitamab as first-line therapy in high-risk LBCL participants or as second-line therapy in LBCL participants can help to control the disease.
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 is a single-arm, open-label, dose-escalation phase I clinical study to explore the safety, tolerability, and cytokinetic characteristics of MC-1-50 cell formulation, and to preliminarily observe the efficacy of MC-1-50 cell formulation in subjects with relapsed/refractory CD19-positive B-cell non-Hodgkin lymphoma.
The use of venetoclax-based therapies for pediatric patients with relapsed or refractory malignancies is increasingly common outside of the clinical trial setting. For patients who cannot swallow tablets, it is common to crush the tablets and dissolve them in liquid to create a solution. However, no PK data exists in adults or children using crushed tablets dissolved in liquid in this manner, and as a result, the venetoclax exposure with this solution is unknown. Primary Objectives • To determine the pharmacokinetics of venetoclax when commercially available tablets are crushed and dissolved into a solution Secondary Objectives - To determine the pharmacokinetics of venetoclax solution in patients receiving concomitant strong and moderate CYP3A inhibitors - To determine potential pharmacokinetic differences based on route of venetoclax solution administration (ie. PO vs NG tube vs G-tube) - To determine the concentration of venetoclax in cerebral spinal fluid when administered as an oral solution
CAR-T cell therapy targeting CD19 has been shown to be effective in heavily-pretreated B-cell ALL or NHL, but relapses post-CAR-T are common, and CD19 antigen loss is one of the reasons. Thus, we supposed that CD19/CD22 bispecific CAR-T cell therapy would be more effective and less relapses would occur in B-ALL or NHL. In this prospective phase 2 clinical trial, we aim to explore the efficacy and safety of CD19/CD22 bispecific CAR-T cell therapy in relapsed/refractory B-ALL or Large B cell lymphoma.
Letermovir is approved for the primary prevention of Cytomegalovirus (CMV) reactivation and infection in hematopoietic stem cell transplant recipients. Letermovir may be beneficial in other clinical presentation where CMV reactivates and may alter clinical outcomes. Recently Chimeric Antigen Receptor (CAR) T cells have been used for the treatment of refractory acute leukemia and B cell lymphoma. Reactivation of chronic viral infections, in particular those belonging to the Herpesviridae family can therefore be observed following CAR-T cells treatment.According to first reports, Cytomegalovirus seems to be the main virus detected. Uncontrolled CMV reactivation leads to CMV disease requiring the use of antiviral drugs associated with either hematological toxicity (ganciclovir) or renal toxicity (foscarnet) and is usually associated with poor outcomes. In addition, CMV interplays with the immune system and decreases the immunosurveillance of tumor cells and facilitates the growth or reactivation of other opportunistic infections. Therefore, CMV reactivation could also impact the outcome of CART cells treatment by increasing the existing risk of opportunistic infections in CART cells recipients and thus by increasing morbidity, length stay or require intensive care. Imbalance of the immune system usually correlates with reactivation of persistent virus like Torquetenovirus (TTV), redondovirus or pegivirus found more frequently in Hematopoietic stem-cell transplantation (HSCT) patients or patients requiring intensive care. Whether reactivations of those persistent viruses are associated or precede CMV reactivation deserve careful investigation to identify as early as possible patients at high risk and who could benefit from antiviral preventive treatment. The objective of this trial is to determine the incidence of CMV reactivation within 3 months after infusion of CAR-T cells in CMV seropositive patients with refractory acute leukemia or B-cell lymphoma.
The purpose is to study the safety, tolerability, pharmacokinetics, pharmacodynamics and efficacy of CAR20(NAP)-T for patients with B-cell malignancies.
