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

The objective of this surveillance is to collect information about adverse drug reaction not expected from the LPD (unknown adverse drug reaction) the incidence of adverse drug reactions in this surveillance factors considered to affect the safety and/or efficacy of this drug.

Imatinib has revolutionized the treatment of chronic myeloid leukemia (CML) and is the current standard of care in the treatment of patients with newly diagnosed CML. However, about 30% of patients still show drug resistance or disease progression. Currently, the most widely studied mechanism of TKI resistance in CML patients is mutations in the ABL kinase region. So far, more than 100 kinase domain mutations have been found in disease progression and imatinib resistance. It is estimated that more than 25% of CML patients will change TKI at least once in their lifetime due to drug resistance or intolerance. The 2020 edition of the "Guidelines for the Diagnosis and Treatment of Chronic Myelogenous Leukemia in China" proposes that patients with F317L/V/I/C, V299L and T315A mutations are more likely to obtain clinical efficacy by switching to the second-generation TKI nilotinib; patients with Y253H, E255K/V and F359C/V/I mutations are more likely to obtain clinical efficacy by switching to the second-generation TKI dasatinib; patients with T315I mutations are resistant to both nilotinib and dasatinib. Flumatinib has been shown to be a more potent inhibitor of BCR-ABL1 tyrosine kinase than imatinib. In vitro studies, it has shown that flumatinib inhibits wild-type and common BCR-ABL mutations(Q252H, V299L, F317L/I, M351T, H396P, etc.) more potently, and the anti-mutation spectrum of flumatinib is similar to nilotinib. Therefore, this study is designed to provide clearer guidance for patients with suboptimal response or failure in the treatment of TKI as well as those who have specific ABL kinase domain mutations during CML treatment.

This study is conducted in patients with newly diagnosed CP CML (Chronic Phase Chronic Myeloid Leukemia) who have achieved EMR (< 10% IS BCR-ABL) at 3 months after first line treatment with dasatinib. Subjects will be allocated to 80mg QD based on EMR (Early Molecular Response) achievement and early safety profile following a standard of care approach.

The purpose of the study is to describe and characterize CML in a large pediatric cohort of patients.

Tyrosine kinase inhibitors (TKI) have revolutionized the management and prognosis of chronic myeloid leukemia (CML). Daily treatment with TKI, which is necessary due to lack of cure, is frequently associated with moderate, chronic and sometimes severe adverse effects. The ability to permanently stop treatment with TKI has thus become a major goal in CML to prevent the occurrence of adverse events, improve quality of life and reduce the general cost of the treatment; we talk about Treatment Free Remission (TFR). It now remains to be demonstrated in a comparative prospective study that a strategy of de-escalation of the TKI treatment dose before treatment discontinuation optimizes TFR results. At the same time, it is possible to reduce adverse reactions and improve the quality of life of patients. In this context, the investigator propose to conduct a randomized clinical trial including CML patients, allowing to compare the results of TFR at 24 months between a sudden stop of treatment after a maintenance phase of dosage for 12 months and a de-escalation arm of dose (dosage reduced by 50%) for 12 months before stopping. A secondary immunological translational objective of this project will be to compare the quantitative and qualitative evolution of innate CD8 T cells between the 2 arms (abrupt cessation of ITK treatment versus progressive withdrawal) and look for a predictive innate CD8 T cells blood signature at the time of stopping treatment of a successful TFR in both arms.

According to the French National Cancer Institute, 35 000 new hematologic cancers are observed in France representing 10% of the new cancers. Chronic Myeloid Leukemia (CML) is a cancer involving the bone marrow and blood cells, the median age at diagnosis is 53 years in the Western world. The prognosis is worse than many other cancers with net survival at 5 years of 26%. Since the approval of imatinib, additional tyrosine kinase inhibitors (TKIs) have been approved by the European Medicine Agency, including the second-generation TKIs nilotinib, dasatinib, and bosutinib and the third-generation TKI ponatinib. Despite their effect on the evolution of CML, there is increasing of cardiovascular toxicities which can impact patient morbidity and mortality. The majority of the cardiovascular toxicities are associated with the second- and third-generation TKIs. Nilotinib and ponatinib cardiovascular toxicity including arterial and venous thromboembolism has decrease the benefit/risk ratio, 10% of patients treated with nilotinib 300 mg twice daily and 15.9% treated with 400 mg twice daily experienced a vascular complication including myocardial infarction /ischemic heart disease, cerebrovascular accidents, or peripheral arterial disease. Regarding ponatinib, serious arterial occlusive adverse reactions occurred in 19% of patients. In an attempt to reduce major adverse cardiovascular events MACE due to nilotinib and ponatinib, currently, then approach is driven by usual clinical practice without any robust published evidence. The investigators aim to perform a national clinical trial, multicenter, prospective, randomized, with two parallel comparative arms: experimental group with cardiovascular active prevention vs non active cardiovascular active prevention based on usual clinical practice. Our hypothesis is that active prevention of cardiovascular toxicities with optimal medical treatment improves the benefit-risk ratio in CML patients. The primary objective is Event Free Survival (EFS) at month 24.

The investigator propose an extension of the previous National, multicentric study, promoting an observational registry, both retrospective and prospective, in order to expand and further characterize the series of Italian patients with Philadelphia-positive, chronic phase CML (CP-CML) who discontinue TKIs in an off-protocol setting. As safety concerns may arise for patients receiving long-term treatments, and due to the growing number of patients discontinuing TKIs in clinical practice, the study aim to collect all available data regarding feasibility and freedom from progression of the cohort of patients.

Chronic myeloid leukemia (CML) consists of 3 clinical stages including chronic phase, accelerated phase and blast crisis. Patients may only survive for few more days to weeks once the disease progresses to blast crisis, even though they might have been stable for several years in the chronic phase. The standard treatment, continuous use of tyrosine kinase inhibitors (TKIs), improves long-term survival, and even may help patients achieve complete remission. Four TKIs are reimbursed by National Health Insurance in Taiwan. Among them, imatinib, nilotinib as well as dasatinib, and ponatinib are the first, second and third generations of TKIs, respectively. Many factors influence the disease control of CML, such as TKI type, genetic mutation and medication adherence. Only 69% of patients followed their physicians' recommendations in a local survey. The medication adherence of TKIs was compromised based on several clinical studies domestically and worldwide due to the slow progression in the chronic phase. Patients might hold or decrease the dose of TKIs on their own when they suffer side effects. Furthermore, the significant intra-subject variations of TKI plasma concentration and drug-drug and drug-food interactions which alter the metabolism of TKIs may lessen therapeutic effect and patient safety. Therefore, this study aims to develop and validate analytic methods of imatinib, dasatinib, nilotinib and ponatinib plasma concentrations. The investigators plan to build the pharmacokinetic models of these 4 TKIs and analyze the impacts of meals, adherence, hepatic enzyme inhibitors and inducers, antacids, proton pump inhibitors and H2 blockers, etc. Adverse drug reactions and treatment outcomes will be evaluated to determine the availability and feasibility of therapeutic drug monitoring of TKIs as part of routine service in pharmacist-led clinics.

Flumatinib is an orally available TKI with high selectivity and potency against BCR-ABL1 kinase. It's a multi-center, open-label, real world study to explore the efficacy and safety of Flumatinib versus Imatinib as the first line therapy in patients with chronic myleiod leukemia(CML) in chronic phase(CP).

The overall survival (OS)of Chronic myeloid leukemia (CML) has been significantly improved since the advent of Tyrosine kinase inhibitors (TKIs) .Nevertheless, there still exists a amount of patients who has poor response or intolerance for TKI drugs( Imatinib, dasatinib, nilotinib). Flumatinib has been shown to be a more potent inhibitor of BCR-ABL1 tyrosine kinase than imatinib,and it aslo has better security when compared to other TKIs(Imatinib, dasatinib, nilotinib).It will be a better chioce for CML patients.
