Filter by:This is a Phase I-II, multi-center, open-label, FIH study comprising of 2 study parts (Phase Ia, Phase Ib). The Phase Ia (dose escalation) part of the study is designed to determine the safety, tolerability, and maximum tolerated dose (MTD)/recommended dose for expansion (RP2D) of BR101801 in subjects with relapsed/refractory B cell lymphoma, chronic lymphocytic leukemia (CLL)/small lymphocytic leukemia (SLL), and peripheral T cell lymphoma (PTCL). The Phase Ib (dose expansion) part of the study is designed to assess tumor response and safety in specific advanced relapsed/refractory Peripheral T-cell lymphoma(PTCL) at a dose of BR101801 identified in Phase Ia. Once the RP2D has been determined in Phase Ia (dose escalation), Phase Ib (dose expansion) will commence.
Phase 2, two cohort trial evaluating the addition of ublituximab and umbralisib on the rate of minimal residual disease (MRD) negativity in participants with Chronic Lymphocytic Leukemia (CLL), who are currently on treatment with ibrutinib, alacabrutinib or venetoclax.
This is a global, Phase IIIb, multicenter, open-label, single-arm study to evaluate the safety and efficacy of acalabrutinib 100 mg twice daily (bid) in approximately 540 participants with chronic lymphocytic leukemia (CLL). Participants will be enrolled into 3 following cohorts: treatment-naive (TN), relapsed/refractory (R/R), and prior ibrutinib therapy. For this study, participants in the UK will be enrolled ONLY into the R/R cohort or the prior ibrutinib cohort. Participants in the US will be enrolled ONLY into the TN or R/R cohort. Participants will remain on study intervention until completion of 48 cycles (28 days per cycle), or until study intervention discontinuation due to, for example disease progression, or toxicity, withdrawal of consent, loss to follow-up, death, or study termination by the sponsor whichever occurs first. The duration of the study will be approximately 72 months from the first participant enrolled. This duration includes an estimated 24-month recruitment time and an assumed 48 cycles of study intervention (28 days per cycle); additional study time will be accrued during the Disease Follow up period for those participants remaining on study intervention after completion of 48 cycles prior to the final data cutoff (DCO) (the amount of time will vary by participant).
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.
This is a prospective multicenter phase 2 study designed with the purpose to evaluate the response rate and safety of treatment with FCR/BR alternating with ibrutinib in treatment-naive patients with chronic lymphocytic leukemia.
In recent years, considerable progress has been made in understanding the biology of chronic lymphocytic leukemia (CLL), resulting in the emergence of new therapeutic agents that have significantly improved the long-term survival of patients. However, LLC is still considered an incurable disease. Cytogenetic abnormalities are frequently found in this pathology. Some abnormalities are associated with a more aggressive disease and a poor prognosis. The deletion of chromosome 17p (del (17p)), in particular, makes leukemic cells more resistant to standard therapy. Chromosome 17p contains the Tumor Protein 53 gene (TP53) which encodes the tumor suppressor protein 53 (P53) protein. P53 plays a central role in the regulation of important cellular functions such as DNA damage response, cell cycle regulation, apoptosis, and drug sensitivity of chemotherapies. In patients with CLL, the loss of p53 function is a major factor of chemoresistance and is associated with an adverse prognosis. The deletion (17p) is observed in approximately 5 to 10% of patients with CLL. In contrast, mutations in the TP53 gene are observed in approximately 30% of patients with CLL. This means that about one-third of patients with CLL have p53 dysfunction. TP53 and / or del (17p) mutated LLC cells show marked mitochondrial dysfunction. This dysfunction is responsible for a deregulation of intracellular redox phenomena, leading to an increase in oxidative stress and an overproduction of reactive oxygen derivatives (ROS). Dimethyl Ampal Thiolester (DIMATE) is an active, competitive and irreversible inhibitor of aldehyde dehydrogenases (ALDH) 1 and 3. In vitro, DIMATE eradicates human cells from acute myeloblastic leukemia (AML). In patients with CLL, current treatments, particularly effective, do not specifically target pathological B cells. This results in chronic B lymphopenia and hypogammaglobulinemias that provide severe long-term infections, which is the leading cause of death in patients with CLL. Through this study, we will study, in vitro, the expression of ALDH 1, 3, 9 but also of glutathione (GSH) and ROS on tumor B lymphocytes and healthy patients carrying an LLC. Depending on the differences in expression observed, DIMATE could specifically eradicate leukemic lymphocyte cells by sparing healthy lymphocytes, a hypothesis that will be tested in vitro. A special evaluation will be made in patients with del (17) and / or TP53 mutation whose prognosis is still considered unfavorable despite new therapeutic advances.
This is a phase I/II study to evaluate the feasibility, safety and preliminary antitumor efficacy of rapcabtagene autoleucel (also known as YTB323). Rapcabtagene autoleucel will be investigated in combination with ibrutinib in chronic lymphocytic leukemia (CLL)/small lymphocytic lymphoma (SLL) and as single agent in diffuse large B-cell lymphoma (3L+ DLBCL), adult acute lymphoblastic leukemia (ALL) and 1st Line High Risk Large B-Cell Lymphoma (1L HR LBCL).
This phase II trial studies how well the combination of ibrutinib and venetoclax works in treating patients with chronic lymphocytic leukemia whose cancer has stopped responding to ibrutinib alone. Both ibrutinib and venetoclax may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Giving ibrutinib and venetoclax together after development of ibrutinib resistance may work better than discontinuing ibrutinib and switching to other chemotherapy drugs.
This study is investigating the efficacy of PD-L1 and PD-L2 peptides in untreated CLL patients with unmutated IGHV gene status.
The purpose of this study is to assess the safety, tolerability, pharmacokinetic and pharmacodynamic properties of APG-2575 in patients with relapse or refractory chronic lymphocytic leukemia and non-hodgkin's lymphoma.
