On behalf of the Israel CLL study group the investigators will evaluate the efficacy and safety of BNT162b2 mRNA Covid-19 Vaccine in patients with chronic lymphocytic leukemia
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 research study is trying to determine which patients with newly diagnosed or relapsed/refractory chronic lymphocytic leukemia (CLL) or small lymphocytic lymphoma (SLL), as grouped by their risk for tumor lysis syndrome (TLS), are able to safely tolerate an accelerated, daily venetoclax dose ramp-up rather than the standard approved schedule (5-week dose ramp-up). The name of the study drug involved in this study is: - Venetoclax The following drugs may also be included in some participants treatment regimen: - Obinutuzumab - Rituximab
This study aims to evaluate the safety and feasibility of hCD19.IL15.CAR-iNKT cells in treating patients with relapsed/refractory/high-risk B-cell tumors.
This is a single-center, open-label, single-arm study to evaluate the primary safety and efficacy of anti-CD19 chimeric antigen receptor(CAR)-modified NK cells(CAR-NK-CD19) in patients with relapsed or refractory hematological malignancies.
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.
This is a Phase 1, multi-center, open-label study with a dose-escalation phase (Phase 1a) and a cohort expansion phase (Phase 1b), to evaluate the safety, tolerability, and PK profile of LP-118 under a once daily oral dosing schedule in up to 100 subjects.
Ibrutinib, an inhibitor of Bruton´s tyrosine kinase (BTK) is approved in CLL as continuous, daily administration of 420 mg orally until progression. Ibrutinib drug costs in health care are rapidly increasing and are difficult to predict, as long-term follow up analyses have shown that many patients remain on therapy for several years, in some cases even many years. It has been observed that patients who stop ibrutinib due to side effects may often remain with continued CLL disease control i.e. in stable partial remission even when off ibrutinib therapy. There are also emerging data on mutations within BTK, with loss of efficacy of ibrutinib, during long-term continuous administration. These observations raise the question whether alternative dosing strategies may be feasible. This pilot study will explore intermittent and repeated dosing of ibrutinib, until alternative therapy is required due to resistance or intolerance to ibrutinib. An "ON-OFF" dosing strategy will be applied, where advanced-phase CLL patients who have received at least 6 months of ibrutinib and who have achieved a stable PR will stop ibrutinib and be followed off therapy until clinical progression, at which ibrutinib will be re-instituted. Such "ON-OFF" ibrutinib cycles may be repeated until non-tolerability or resistance, or need of continuous dosing of ibrutinib (i.e. early progression when off the drug). If successful, the study will indicate a way forward towards reducing ibrutinib drug costs in health care without affecting long-term disease control, possibly also with fewer ibrutinib-related side effects due to a lower cumulative dose of ibrutinib. Long-term effects on potential mutations within BTK and its downstream signaling molecules will also be analysed.
This is a multicenter non-interventional observational study conducted with a single hand arm to collect real-world data. In this study, commercially available acalabrutinib will be used as prescribed treatment for CLL as per the treating physician's best clinical judgement. No additional procedures besides those already used in the routine clinical practice will be applied to the patients. Treatment assignment will be done according to the current practice. A multi-center collaborative effort in 15 centers selected from regions within Russia will help capture more patients into the database, rather than limiting the data to a single institution. This will be critical for: - increasing database sample size - reducing bias (single institution bias) - increasing result's generalizability to the whole Russian population Being an observational study, only data available from routine clinical practice and standard of care (SoC), in line with national and international laws and regulations, will be recorded. Patients will be treated according to prescribing information, with visit frequency and assessments performed according to routine medical practice and SoC. Only data corresponding to these visits and assessments will be collected as part of the study. Data for the study will be transcribed and entered into an electronic Case Report Form (eCRF) from the patient's medical records. The site investigator will be responsible for ensuring that all required data is collected and entered into the eCRF with the involvement of clinical research organization
