Active clinical trials for "Leukemia, Lymphoid"

It is an open-label dose-escalating study in sequential cohorts to assess safety and pharmacokinetics of GNR-084.

Relapsed and refractory B cell acute lymphoblastic leukemia (B-ALL) shows unfavorable prognosis, especially for adult patients. Besides, minimal residual disease (MRD) positive at transplant has been considered risk factor for relapse after transplantation. Worse yet, there is no standard management for these patients. Chimeric antigen receptor T cells (CAR-T cells) has been recognized a promising treatment option for treating B cell derived malignancy. The purpose of this study is to evaluate the efficacy and safety of chimeric antigen receptor 19 (CD19-CAR-T2 Cells) infusions in patients with CD19+ ALL.

This is a single-arm, open-label, multi-center phase I study using blinatumomab for pediatric B-cell acute lymphoblastic leukemia patients with positive of minimal residual disease. 1 Cycle of blinatumomab treatment followed by hematopoietic stem cell transplantation. Blinatumomab has approved to treat adults and children with B-cell precursor ALL who are in remission but still have MRD. However, data on the effects and safety of blinatumomab in children with B-precursor ALL with MRD positive are insufficient.

This study is a phase II trial of belimumab in combination with rituximab/venetoclax in patients with refractory or relapsed chronic lymphocytic leukemia (CLL). Treatment of CLL has drastically changed in the past years as new therapeutic agents have gained clinical approval. The combination rituximab/venetoclax over a course of two years is approved as second line therapy especially in patients with high risk CLL (del17p), showing high remission rates and achievement of MRD (minimal residual disease) negativity. The next goals in CLL therapy are now to increase the rate of MRD negativity and to achieve an earlier MRD negativity during the course of treatment to allow for a reduction of treatment time and therefore treatment-induced toxicities. In line with other hematologic diseases, progression free survival depends on remission status, especially MRD negativity, after last treatment as MRD positivity after therapy indicates the persistence of treatment resistant CLL cells. One mechanism of therapy resistance has been described as reduced sensitivity to rituximab-induced antibody dependent cell-mediated cytotoxicity (ADCC) by natural killer (NK) cell production of B-lymphocyte stimulator (BlyS, also called BAFF), which can be bound by belimumab, a human anti-BAFF antibody. Moreover, recombinant human (rh)BAFF can dose dependently reverse cytotoxic effects of venetoclax, which could also be restored by the application of belimumab. This led to the conceptualization of this clinical trial, in which belimumab is applied as a weekly subcutaneous injection in combination with standardrituximab/venetoclax treatment for up to 24 months in relapsed and refractory CLL patients. By removing BAFF from the CLL microenvironment we aim to increase the efficacy of rituximab/venetoclax treatment to achieve higher and earlier MRD negativity rates and allow for an abbreviated treatment.

The irreversible Bruton's Tyrosine Kinase (BTK) inhibitor acalabrutinib (ACA) has potent clinical activity as a single agent in patients with treatment naive and Relapsed/Refractory Chronic Lymphocytic Leukemia (CLL). However, a growing body of concerns is raising regarding the unlimited administration of targeted therapy as BTKi. First, long-term treatments expose the patients to increased risk of specific adverse events (infections, bleeding events or cardiovascular problems). Second, continuous administration might also increase the risk of clonal evolution and therapeutic resistance resulting from genetic alterations such as BTK or PLCG2 mutations. Discontinuation of therapy after a fixed period is expected to prevent these events. Rapid and deep responses yielded by ACA in elderly patients pave the way of investigating a limited 18-months period schedule. This study aims to investigate the 1-year PFS upon ACA discontinuation and efficacy of restarting ACA upon symptomatic relapse.

This is a randomized, phase II, double-blind, placebo-controlled trial with planned crossover to the intervention arm after 1 year. Consenting patients with CLL who have had at least one NMSC diagnosed in the past year will be randomized to receive either oral nicotinamide 500 mg twice daily (BID) for 1 year or oral placebo 1 tablet twice daily for 1 year. Patients will be stratified according to CLL therapy and the number of prior NMSC. At the end of 1 year, patients will undergo dermatologic examination and the number of new NMSC will be quantified. The number of patients who develop new NMSC in each arm will be documented. At this time, patients will be unblinded and all patients will receive Nicotinamide 500 mg BID for an additional year. At the end of this second year, patients will again undergo dermatologic examination, and the number of new NMSC will be quantified. The number of patients who develop NMSC will be documented. Skin biopsies will be taken for correlative studies. Enrollment will be split into two parts separated by an interim analysis. Part 1 will accrue 40 patients: 20 to each arm. After 40 patients have completed their 12 month visit an interim futility analysis will be conducted prior to recruiting more patients. The study will stop if the difference in the number of patients with NMSC between control and treatment arms is 0 or less (i.e., absolutely no evidence that the treatment is better than control). If the trial is not stopped, the investigators will proceed with Part 2 and recruit 46 more patients.

This is a single arm, open-label, non-randomized, dose-escalation, phase I study to determine the safety and efficacy of ssCART-19 in the treatment of patients with CD19 positive relapsed or refractory acute lymphoblastic leukemia.

This is a single-center, open-label, single-arm study to evaluate the primary safety and efficacy of anti-CD7 chimeric antigen receptor(CAR)-modified T cells(CAR7-Ts) in patients with relapsed or refractory T lymphoid malignancies.

The purpose of this phase 2/3 study is to confirm the recommended doses and to evaluate the safety and pharmacodynamics of Calaspargase pegol for the treatment of adult patients with Philadelphia-negative Acute Lymphoblastic Leukemia.

Chronic lymphocytic leukemia (CLL) is the most common leukemia (cancer of blood cells). The purpose of this study is to assess retreatment with venetoclax-obinutuzumab (VenG) in participants previously treated with fixed duration first-line (IL) therapy of venetoclax in combination with an anti-CD20 antibody +/- X (where X is any additional drug). Adverse events and change in disease activity will be assessed. Venetoclax is an approved drug for the treatment of CLL. Study doctors put the participants in 1 of 2 groups, called cohorts, based on when symptoms of CLL came back after previous treatment in first-line. Approximately 75 adult participants with CLL who have been treated with venetoclax in combination with an anti-CD20 antibody +/- X will be enrolled in the study in approximately 60 sites worldwide. Participants will receive intravenous (IV) obinutuzumab + oral venetoclax (VenG) in 28-day cycles for a total of 6 cycles per cohort, followed by 6 to 18 cycles of venetoclax alone, for a total treatment of 12 to 24 cycles, depending on the cohort. There may be higher treatment burden for participants in this trial compared to their standard of care. Participants will attend regular visits during the study at a hospital or clinic. The effect of the treatment will be checked by medical assessments, blood tests, checking for side effects and completing questionnaires.
