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

Chronic lymphocytic leukemia (CLL) is the most common leukemia in Western countries, representing approximately 30% of all adult leukemias. There is a large difference in proportion of malignant lymphoma between the United States (US) and Japan was seen in CLL/small lymphocytic lymphoma (SLL) (Japan, 3.2%; US, 24.1%). The purpose of this study is to assess how well venetoclax works in combination with obinutuzumab (V+G, Cohort 1) or with ibrutinib (V+I, Cohort 2) in Japanese participants with previously untreated CLL/Small Lymphocytic Lymphoma (SLL). Adverse events and change in disease activity will be assessed. Venetoclax is an approved drug for the treatment of CLL and SLL. Study doctors put the participants in 1 of 2 groups, called treatment arms, based on variable alternating assignment. Approximately 20 adult participants with previously untreated CLL/SLL will be enrolled in the study in approximately 20 sites in Japan. Participants in group 1 will receive oral venetoclax + intravenous (IV) obinutuzumab (V+G) in 28-day cycles for a total of 12 cycles, and participants in group 2 will receive oral venetoclax + oral ibrutinib (V+I) in 28-day cycles for a total of 15 cycles. 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, and checking for side effects.

To determine whether protective antibody levels increase after booster dosing with the Moderna COVID-19 vaccine in patients diagnosed with Hematologic Malignancies who have low antibody levels after a prior first vaccination with any of the SARS-CoV2 vaccines that were authorized for use in the USA. Researchers will also assess whether the booster dosing with the Moderna COVID-19 vaccine is safe in patients with multiple myeloma, amyloidosis, or other blood cancers.

This phase II trial studies the effect of acalabrutinib in treating autoimmune hemolytic anemia that has come back (relapsed) or has not responded to previous treatment (refractory) in patients with chronic lymphocytic leukemia. Acalabrutinib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth.

The aim of this study is to compare the efficacy of continuous ibrutinib monotherapy with fixed-duration venetoclax plus obinutuzumab and fixed-duration ibrutinib plus venetoclax by measuring progression-free survival (PFS) in patients with previously untreated CLL.

The aim of this trial is to show the efficacy, safety and feasibility of acalabrutinib in a cohort of CLL-patients ≥80 years or with a FRAIL scale score >2 (5-item questionnaire to be filled out by the patient)

The purpose of this study is to determine the safety and recommended Phase 2 dose (RP2D) of JNJ-67856633 and ibrutinib in combination in participants with B cell non-Hodgkin lymphoma (NHL) and chronic lymphocytic leukemia (CLL).

The purpose of the study is to investigate whether the combination of rituximab and high dose methylprednisolone can be given together, can reduce the amount of cancer cells that are present prior to starting venetoclax, and therefore make it safer to take venetoclax. Patients with relapsed or refractory chronic lymphocytic leukemia (CLL) or small lymphocytic lymphoma (SLL) will be treated in this study. Subjects will be assessed for their risk of tumor lysis syndrome (TLS), a potentially serious side effect associated with venetoclax and rituxan. TLS is caused by the fast breakdown of cancer cells. TLS can lead to kidney failure or abnormal heart rhythm. Depending on their TLS risk, patients will be assigned to one of two treatment arms. Patients who are at high risk for TLS at baseline will receive HDMP/Rituximab for 1 cycle before beginning venetoclax. Patients who are at low risk for TLS at baseline will not receive HDMP/Rituximab and will instead start directly with venetoclax. Once the proper dose of venetoclax is reached, both arms will continue venetoclax for up to 2 years and receive rituximab for 5 cycles. The purpose is to determine if HDMP/Rituximab prior to venetoclax is efficient at reducing tumor burden and lowering the risk of developing TLS. Although all of these drugs are approved by the FDA for the treatment of patients with CLL or SLL, and although the combination of rituximab and venetoclax is approved by the FDA for the treatment of patients with CLL or SLL, the combination and dosing schedule in this trial are considered experimental.

Background: Chronic lymphocytic leukemia and small lymphocytic lymphoma (hereby referred as CLL) are tumors of B cells. A subset of patients categorized as high-risk CLL has a poor clinical outcome when treated with conventional chemotherapy. This single-arm, phase II study investigates the combination of ibrutinib, fludarabine and pembrolizumab for treatment of CLL. Ibrutinib is an orally administered therapy for CLL. Fludarabine is a well-tolerated drug that has been widely used to treat CLL. Also, fludarabine can modulate CLL cells as well as immune cells that support the growth of CLL cells. Pembrolizumab recruits immune cells to attack CLL cells. With this approach we hope to achieve a greater reduction in CLL cells than with single agent ibrutinib and to restore healthier immune system that could contribute to durable responses. Objective: To investigate the rate of complete response to ibrutinib, short course fludarabine and pembrolizumab. Eligibility: Patients with active CLL meeting treatment indications defined by 2008 International Workshop on CLL (IWCLL) consensus guideline. High-risk CLL defined by one of the following: Relapsed/refractory disease status, or Presence of high-risk mutations regardless of prior treatment status: deletion 17p, TP53 mutation, NOTCH1 mutation, SF3B1 mutation, MYC aberration, or complex cytogenetics. Design: This is a single-arm, open-label phase II study. Timeline: Treatment on this study is given in cycles from cycle -3 to 17, then in months beyond cycle 17. Cycles -3 to -1 are 28-day cycles. Cycles 1 to 17 are 21-day cycles. After completion of 1 year of pembrolizumab, the time on study is by chronological months on study from starting pembrolizumab. Treatment plan: Ibrutinib is given starting from cycle -3 and continuously until disease progression or intolerable side effects occur. Fludarabine is given on D1-D5 on cycle -2 only Pembrolizumab is given every 3 weeks starting from cycle 1 for 1 year. Minimal residual disease will be measured at 2 years from cycle 1 to determine the need for long- term treatment with ibrutinib. Previously-untreated patients who achieve minimal residual disease negativity will stop ibrutinib. Patients who do not achieve minimal residual disease negativity or who has Relapsed/refractory CLL will continue ibrutinib.

The aim of the current trial is to evaluate if combination treatment with venetoclax + ibrutinib in patients with relapsed or refractory chronic lymphocytic leukemia (RR CLL) can lead to MRD negativity, which may induce long lasting remissions for MRD-negative patients randomized to stopping treatment after 15 induction cycles.

This is a multicenter, 2-cohort Phase 2 study assessing both minimal residual disease (MRD)-guided discontinuation and fixed duration therapy with the combination of ibrutinib + venetoclax in subjects with treatment-naïve CLL or SLL.
