Active clinical trials for "Leukemia, Lymphocytic, Chronic, B-Cell"

The purpose of this study is to test the safety of Iodine-131 Anti-B1 Antibody, to see what effects it has on patients with CLL and to determine the highest dose of Iodine-131 Anti-B1 Antibody that can be given without causing severe side effects.

The purpose of this study is to evaluate the safety, tolerability and pharmacokinetics of SHC014748M in patients with relapsed or refractory indolent B-cell hematologic malignancies.

This is a phase I, interventional, single arm, open label, treatment study to evaluate the safety and tolerability of CD19 CARvac in patients with relapsed and/or refractory B cell malignancies.

This study is prospective, open-label, single arm observational study to assess efficacy of obinutuzumab plus chlorambucil (GC) chemotherapy in treatment naïve CLL, and prognostic impact of genetic alterations for CLL using NGS.

This is a phase I trial of the IL-1 receptor antagonist anakinra in chronic lymphocytic leukemia patients who are predicted to eventually require first-line therapy based on conventional clinical criteria. Three groups of 4 patients will be injected subcutaneously with either 100 mg daily or 100 mg twice daily or 200 mg twice daily for 7 cycles of 4 weeks each to determine the dose-limiting toxicity of anakinra in this population. Clinical responses will be determined by conventional IWCLL criteria. It is hoped anakinra will prevent disease progression with little toxicity. The study is anticipated to be completed within a year.

This study will assess whether there are differences in effectiveness and safety outcomes among PI3K-treated patients in a real world registry, compared to patients treated in clinical trials.

This research trial studies the mechanisms of idelalisib-associated diarrhea in patients with chronic lymphocytic leukemia, indolent non-hodgkin lymphoma, or small lymphocytic lymphoma that has come back after a period of improvement. The cancer treatment drug idelalisib triggers diarrhea in some patients. Studying stool, blood, and tissue samples in the lab from patients who are given idelalisib may help doctors learn more about the side effects and may help to treat them in future patients.

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.

The combination of Fludarabine and Cyclophosphamide have yielded overall response rates of over 80% in previously untreated patients with indolent Non-Hodgkin-Lymphoma. However, hematotoxicity rates were high with Grade 3 and 4 toxicities of over 50%. Several studies have indicated that the treatment with Pentostatin and Cyclophosphamide causes lower hematotoxicity rates than the combination of Fludarabine and Cyclophosphamide. To evaluate the efficacy and safety of treatment with Pentostatin/Cyclophosphamide immuno-chemotherapy for patients with newly diagnosed or relapsed Immunocytoma/Morbus Waldenström, B-cell chronic lymphocytic leukemia (B-CLL) and other indolent CD20-positive B-NHL, an open, non-randomized, multi-center prospective phase II-study to evaluate the efficacy and safety of treatment with immuno-chemotherapy is conducted. Treatment consists of 6 courses of Pentostatin (4mg/m² on day 1), Cyclophosphamide (600mg/m² on day 1) and Rituximab (375mg/m² on day 0) administered every three weeks. Patients achieving complete or partial remission undergo maintenance therapy consisting of 8 courses of Rituximab (375mg/m²) administered every three months over a period of 2 years.

Patients with chemo refractory CLL have a poor prognosis. 2 independent mechanisms are attributed to the development of chemoresistance in CLL. The first is a shift in the balance between pro- and anti-apoptotic regulators. The second mechanism is based on acquired mutations resulting in a dysfunctional p53 response. Recent studies indicate that the tyrosine kinase inhibitor dasatinib acts synergistically with both purine analogies and alkylating agents. Also, dasatinib has the potency to restore the apoptotic balance of CLL cells. Hypothesis: Dasatinib will be clinically active in chemo-refractory CLL patients and will act synergistically with the purine-analogue fludarabine.
