Active clinical trials for "Leukemia, Myelogenous, Chronic, BCR-ABL Positive"

Chronic myeloid leukaemia (CML) is due to a chromosomal abnormality in white blood cells which results in abnormal multiplication. CML in its earlier, slower growing chronic phase (CP) is well controlled by the tyrosine kinase inhibitor (TKI) drug imatinib, which targets the consequences of the chromosomal abnormality, inducing a response and subsequent remission (as measured using molecular techniques on patient blood or bone marrow samples in the lab). Dasatinib, a newer TKI drug, similar in design to imatinib, gives a more rapid molecular response, however the long term side-effects are less known than imatinib. This study will investigate the efficacy and safety of a treatment plan for patients with newly diagnosed CML-CP, where dasatinib will be used to more rapidly induce a molecular response (MR3.0) within 12 months, after which imatinib will be used to maintain the CML in that remission. It is hypothesised that imatinib is safe and effective in maintaining MR3.0 in patients with CML who achieve MR3.0 at 12 months following initial induction therapy with dasatinib.

This phase II trial studies the side effect of busulfan, fludarabine phosphate, and post-transplant cyclophosphamide in treating patients with blood cancer undergoing donor stem cell transplant. Drugs used in chemotherapy, such as busulfan, fludarabine phosphate and cyclophosphamide work in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving chemotherapy such as busulfan and fludarabine phosphate before a donor stem cell transplant helps stop the growth of cells in the bone marrow, including normal blood-forming cells (stem cells) and cancer cells. Sometimes the transplanted cells from a donor can make an immune response against the body's normal cells (called graft-versus-host disease). Giving cyclophosphamide after the transplant may stop this from happening. Once the donated stem cells begin working, the patient's immune system may see the remaining cancer cells as not belonging in the patient's body and destroy them.

Adult male and female patients with newly diagnosed Philadelphia chromosome positive (Ph+) and/or BCR-ABL1 positive CML can be included in the study until 3 months after diagnosis. A <4 week pretreatment with hydroxyurea is permitted. Patients treated for <6 weeks with nilotinib 300 mg BID, imatinib 400 mg QD, dasatinib 100 mg QD or without any therapy are eligible for recruitment and will be allocated to the respective cohort. All patients must provide written informed consent to be enrolled in the trial. Cohorts were designed to allow assessment of QD and BID asciminib based combinations to optimize quality of life and compliance. Patients will not be randomized. In general, cohorts will be filled consecutively. Asciminib therapy will be commenced 12 weeks after start of nilotinib, imatinib or dasatinib and after recovery of hematopoiesis or in case of no therapy so far 6 weeks after diagnosis as first line treatment. Referred patients already treated with imatinib, nilotinib or dasatinib will remain on the initial drug and will be allocated to the respective cohort.

The main goal of this study is to evaluate the stability of molecular response (major and deep molecular response( MMR and DMR)) in patients with chronic myeloid leukemia (CML) with stable DMR after two-stage dose reduction phase and discontinuation treatment TKI: imatinib, nilotinib, dasatinib and bosutinib.

The purpose of the present study is to determine the rate of successful treatment-free remission (TFR) within the first 52 weeks following cessation of ponatinib treatment in patients who achieved MR4. Eligible patients had been previously treated with TKI and when patients achieved an optimal molecular response, TKI treatment was discontinued. After loss of response, patients were treated again with a TKI treatment and have documented MR4 for one year at the time of switch to ponatinib to study entry. MR4 is defined as BCR-ABL transcript level ≤ 0.01% IS or undetectable BCR-ABL levels with sample sensitivity of at least 4 log.

The investigators hypothesize that, in newly diagnosed de novo chronic phase CML patients, an induction treatment with ponatinib for 6 months should increase the rate of patients reaching a stable MR4.5 allowing cessation of imatinib treatment. The investigators proposal is to conduct a multicenter, Phase II trial to evaluate the safety, clinical and biological activity of an induction treatment with ponatinib for 6 months, followed by a consolidation treatment with imatinib in newly diagnosed de novo chronic phase CML patients.

This phase II trial studies how well ABL001 works in treating patients with chronic myeloid leukemia who are on therapy with tyrosine kinase inhibitor. ABL001 may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Giving ABL001 and tyrosine kinase inhibitor together may work better than tyrosine kinase inhibitor alone in treating patients with chronic myeloid leukemia.

The purpose of this study is to evaluate the efficacy of HQP1351 in patients with chronic myeloid leukemia in chronic phase (CML-CP) harboring T315I mutation. The efficacy of HQP1351 was determined by evaluating the subjects' major cytogenetic response (MCyR).

This phase II trial studies how well dasatinib and venetoclax work in treating patients with Philadelphia chromosome positive or BCR-ABL1 positive early chronic phase chronic myelogenous leukemia. Dasatinib and venetoclax may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth.

Fludarabine, cyclophosphamide, and rituximab (FCR) is the gold treatment for fit and young patients with Chronic Lymphoid Leukemia (CLL). However, patients with a mutation known as IGVH unmutated and patients with a particular characteristic known as 'disrupted TP53' show an inferior outcome after FCR in terms of survival. Venetoclax as a single agent or combined with rituximab is an effective treatment for relapsed/refractory patients with IGVH unmutated CLL and/or del(17p) and is associated with a high rate of clinical responses.
