Filter by:Immunotherapy offers an extremely precise approach with the potential to eliminate cancer cells specifically. The newly designed CD19 targeted ICAR19 T cells can specifically kill CD19+ tumor cells. ICAR19 CART used the second generation of CART designation. In this study, the participants will receive several doses of autologous ICAR19 T cells and the investigators will determine the safety and therapeutic effects of these cells.
This is the second stage of the previous anti-CD19 CAR-T therapy (NCT02965092). The study aims to evaluate the safety and efficacy of consolidative allo-HSCT following CAR-T therapy in patients with relapsed or refractory B cell Malignancies.
For micro residual disease (MRD) positive patients who have undergone at least 2 cycles chemotherapies for their CD19+ B-cell malignancies, there would be much more risks for them to receive hematological stem cell transplantation (HSCT) than MRD- patients. In order to reduce HSCT-related adverse events for these kind of patients, investigators plan to conduct CAR-T therapies on them first to make them achieve MRD- statuses, and then transfer them to HSCT.
A total of 40 participants will be recruited, with 20 participants in each of the following subcategories: A) High grade lymphoma (DLBCL, FL grade 3b, transformed FL) (n=20) B) Low grade lymphoma (e.g. FL grade 1, 2 or 3a, MZL, MCL) (n=20) The main purpose for having two experimental treatment arms is to provide a comparator for the translational endpoints, i.e. to assess whether the differences observed are due to the addition of varlilumab to rituximab. The only difference between Arm A and Arm B is the delay in administration of varlilumab in cycle 1, which is on Day 2 in Arm A and Day 8 in Arm B. As the post-treatment tissue collection occurs on Day 7/8, prior to administration of varlilumab in Arm B, samples will be obtained from participants that have either been treated with rituximab alone, or both rituximab and varlilumab. To minimise any potential risks to the patient as a result of a repeat biopsy on Day 7/8, a prerequisite for entry to the trial is that the participants must have accessible sites for biopsy. Difference in response rates between Arm A and Arm B are not expected.
A single arm, open-label pilot study is designed to determine the safety, efficacy and cytokinetics of CAR T cells in patients with malignant tumors with positive antigen targets. CAR T cells are genetically engineered to express single-chain variable fragment (scFv) targeting indication-specific antigens. The investigational CAR T cells and proposed indications are as follows: CAR-CD19 T cells for B cell leukaemia/lymphoma; CAR-BCMA T cells for myeloma; CAR-GPC3 T cell for hepatocellular carcinoma; CAR-CLD18 T cells for pancreatic carcinoma and adenocarcinoma of esophagogastric junction.
The major aim of this research is to assess the feasibility, safety and effectiveness of CD19 CAR-T Cell Therapy for Relapsed/ Refractory Acute Lymphoblastic Leukemia/ B cell Lymphoma patients who have applied it.
It's a single arm, open label prospective study, in which the safety and efficacy of autologous CAR-T are evaluated in refractory/relapsed B cell lymphoma patients. Abbreviation: CAR-T: Chimeric Antigen Receptor T-Cell Immunotherapy.
This phase I clinical study was to investigate the safety, tolerability, and pharmacokinetics/pharmacodynamics of Bruton tyrosine kinase (BTK) inhibitor zanubrutinib (BGB-3111) in Chinese participants with B-cell lymphoma by conducting in two stages, the first stage being the safety assessment of dose and the second stage being the dose expansion. Part I: Safety evaluation - according to the results of preclinical toxicological trials and the results of the phase I clinical study conducted in Australia and New Zealand, two regimens of zanubrutinib 320 milligrams (mg) daily (160 mg twice daily [BID]), administered in the morning and at night, or 320 mg once daily [QD]) and "3+3" design was adopted for the assessment. The recommended dose and method of administration of the phase II clinical study was determined according to the Part I results. Part II: Dose expansion - this stage was to further evaluate the preliminary anti-tumor effects of zanubrutinib in Chinese participants with follicular lymphoma (FL) or marginal zone lymphoma (MZL), approximately 20 participants with relapsed or refractory FL or MZL were to be enrolled. The recommended Phase 2 dose (RP2D) was used in Part II.
Autologous T cells engineered to express chimeric antigen receptors (CARs) against leukemia antigens such as CD19 on B cells have shown promising results for the treatment of relapsed or refractory B-cell malignancies. However, a subset of cancer patients especially heavily pretreated cancer patients could be unable to receive this highly active therapy because of failed expansion. Moreover, it is still a challenge to manufacture an effective therapeutic product for infant cancer patients due to their small blood volume. On the other hand, the inherent characters of autologous CAR-T cell therapy including personalized autologous T cell manufacturing and widely "distributed" approach result in the difficulty of industrialization of autologous CAR-T cell therapy. Universal CD19-specific CAR-T cell(UCART019),derived from one or more healthy unrelated donors but could avoid graft-versus-host-disease (GVHD) and minimize their immunogenicity, is undoubtedly an alternative option to address above-mentioned issues. We have generated gene-disrupted allogeneic CD19-directed BBζ CAR-T cells (termed UCART019) by combining the lentiviral delivery of CAR and CRISPR RNA electroporation to disrupt endogenous TCR and B2M genes simultaneously and will test whether it can evade host-mediated immunity and deliver antileukemic effects without GVHD. The main goal of the phase 1 portion of this phase 1/2 trial is to evaluate the safety and tolerability of several doses of UCART019 in patients with relapsed or refractory CD19+ leukemia and lymphoma, so as to establish the recommended dose and/or schedule of UCART019 for phase 2 portion. The recommended Phase 2 dose will be defined as the highest dose level of UCART019 that induced DLT in fewer than 33% of patients (i.e., one dose level below that which induced DLT in at least two of six patients). Phase 2 portion of the trial will not be initiated until the recommended Phase 2 dose is determined. In the phase 2 portion of this trial, we will mainly determine if UCART019 help the body's immune system eliminate malignant B-cells. Safety of UCART019 and impact of this treatment on survival will also be observed.
This is a clinical study to observe the maximum tolerated dose (MTD) and the safety and feasibility of chimeric antigen receptor 19 (CD19 CART) cells in relapsed and refractory patients with CD19+ B cell lymphoma.
