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

This phase II trial compares the effect of the GEO-CM04S1 vaccine with the current standard of care vaccine in preventing COVID-19 infections in patients with chronic lymphocytic leukemia (CLL). The GEO-CM04S1 vaccine uses a modified vaccinia virus (MVA) backbone that may be more effective at boosting COVID-19 immunity in patients with poor immune responses. MVA strongly induces T cell expansion (infection fighting blood cells) even in the background of a suppressed immune system, which is the case in the targeted CLL patient population. Using the GEO-CM04S1 vaccine may be more effective at preventing COVID-19 infection in patients diagnosed with CLL.

The purpose of this extension study is to provide venetoclax and obtain long-term safety data for subjects who continue to tolerate and derive benefit from receiving venetoclax in ongoing studies.

The proposal is to conduct a prospective, multi-cohort study aiming to decipher molecular profiles/biological characteristics of advanced cancer patients during the course of their disease with longitudinal and sequential analyses of tumor and liquid biopsies. This approach will allow i) to develop a model in order to predict tumor response / resistance in real life conditions and to better understand adaptive mechanisms and ii) to potentially propose therapeutic options to enrolled patients following the review of the biological/molecular data generated during this study and during a Molecular Tumor Board in case of disease progression. This study will include 12 cohorts according to tumor type and standard treatment received (See Inclusion criteria I1). Patient will be enrolled before the initiation of standard anti-cancer treatment.

Metabolic reprogramming has been identified as a hallmark of cancer. Almost a century after Otto Warburg initially discovered increased glycolytic activity in tumor tissue ("Warburg effect"), therapeutic targeting of cancer metabolism has become a field of intense research effort in cancer biology. A growing appreciation of metabolic heterogeneity and complexity is currently reshaping investigators "simplistic" understanding of metabolic reprogramming in cancer. Discovering metabolic vulnerabilities as new treatment targets for cancer requires systematic dissection of metabolic dependencies, fuel preferences, and underlying mechanisms in the specific physiological context. However, today's data on cancer cell metabolic signatures and heterogeneity in their physiological habitat of the human organism is sparse to non-existent representing a critical knowledge gap in designing effective metabolic therapies. Here, the investigators propose a "top-down" approach studying cancer cell metabolism in patients followed by mechanistic in-depth studies in cell culture and animal models to define metabolic vulnerabilities. Investigators will develop a metabolic tracing method to quantitatively characterize metabolic signatures and fuel preferences of leukemic lymphocytes in patients with chronic lymphocytic leukemia (CLL). Isotopic metabolic tracers are nutrients that are chemically identical to the native nutrient. Incorporated stable, non-radioactive isotopes allow investigators to follow their metabolic fate by monitoring conversion of tracer nutrients into downstream metabolites using cutting-edge metabolomics analysis. Using this method, investigators propose to test the hypothesis that leukemic lymphocytes show tissue-specific metabolic preferences that differ from non-leukemic lymphocytes and that ex vivo in-plasma labeling represents a useful model for assaying metabolic activity in leukemic cells in a patient-specific manner.

Background: The drug venetoclax treats chronic lymphocytic leukemia (CLL). Researchers want to find better treatments for CLL. To do that, they need to learn how the drug affects CLL cancer cells and the immune system. Objective: To learn about genetic changes that happen during treatment of CLL with venetoclax. Eligibility: Adults ages 18 and older with relapsed or refractory CLL after at least 1 prior therapy Design: Participants will be screened under a separate protocol. In Phase 1, participants will get venetoclax free of charge through the NIH. Venetoclax is started at a low dose. The dose will be increased every week until participants reach their maximum tolerable dose. This usually take about 5 weeks. Participants will visit the NIH at least once per week. Visits will be about 4 hours. They may have to stay in the hospital to be observed. In Phase 2, participants will continue to get the drug through their local cancer doctor and their health insurance. Patients will also visit the NIH every 6 months, or if their disease progresses. At the NIH participants will have regular health assessments. These will include physical exams and a review of the medicines they are taking. They will talk about how they are feeling. The study included the following tests: Blood draws CT scans: Participants will lie in a machine that takes pictures of the body (maximum 3 per year) Bone marrow biopsies: A small amount of marrow will be taken out of the participant s hip bone with a needle. Optional lymph node biopsies: A small piece of the participant s tissue will be taken out with a needle. The study will last at least 2 years.

The emergence of targeted therapy (ibrutinib, venetoclax, acalabrutinib) has revolutionized the management practices of chronic lymphoid leukemia due to their effectiveness. However, targeted therapy induces a significant additional cost compared to treatment with immunochemotherapy and their use can be problematic due to the frequent occurrence of side effects, which can be serious. In order to improve the current management of patients treated with targeted therapy, the aim of this study is to evaluate the ambulatory medical assistance nurse program. Ambulatory medical assistance is based on regular telephone calls to patient's homes by a specialist nurse and consists of the monitoring, detection and early management of possible adverse effects of targeted therapy, in link with the hematologist. The main objective of this clinical research is to determine efficiency of the ambulatory medical assistance nurse program.

This is a Phase 1/2 dose-escalation study of BTCT4465A (Mosunetuzumab) administered as a single agent and in combination with atezolizumab in participants with relapsed or refractory B-cell NHL and CLL. The study will consist of a dose-escalation stage and an expansion stage where participants will be enrolled into indication-specific cohorts.
