Active clinical trials for "Leukemia"

This observational study aims to study the effectiveness and safety of Obinutuzumab in common clinical practice settings in Argentina. The study population comprises all patients with chronic lymphocytic leukemia (CLL) that have received the indication for treatment with Obinutuzumab as per routine clinical practice.

Although the response rate by first-line treatment has been improved, most adult patients with relapsed or refractory ALL will eventually relapse with poor outcomes regardless of treatments. To further understand current status of the treatment of adult patients with relapsed or refractory ALL in China, the study retrospectively collected diagnosis and treatment data from ALL patients in 14 centers in China. Primary objective: to estimate the proportion of patients in overall response rate (ORR) for early relapsed or primary refractory Philadelphia chromosome negative (Ph-) B-precursor ALL patients following salvage treatment (i.e., proportion of patients in hematological complete remission [CR] and CR with partial recovery of blood cells [CRh*]); Secondary objectives included: to estimate the proportion of patients in CR, CRh* and CRi(CR/CRh*/CRi) and the duration of CR/CRh*/CRi, overall survival, duration of CR/CRh*and the proportion of patients receiving allogeneic hematopoietic stem cell transplantation (AlloHSCT) for early relapsed/primary refractory Ph-B-precursor ALL patients following salvage treatment; Exploratory objectives included: to estimate the efficacy in late relapsed Ph- B-precursor ALL (first remission duration > 12 months) patients and in Ph+ B-precursor ALL patients and specific subgroup patients following salvage treatment.

The study aims to determine the feasibility of a 6-month low glycemic dietary intervention in children and adolescents undergoing treatment for acute lymphoblastic leukemia.

The purpose of this observational study is to evaluate the effectiveness and safety of generic imatinib under usual clinical practice in patients of Philadelphia chromosome-positive (Ph+) chronic myeloid leukemia (CML) patients in chronic phase (CP) in Egypt

Broadly speaking, the goal of this study is to better understand the influence of chemotherapy treatment on the cognitive and neural mechanisms underlying human behavior. Extant literature lacks diversity in studied cancer populations and treatment protocols, and provides limited understanding of the cognitive abilities that are impaired by chemotherapy. To overcome these limitations, this study will employ a sophisticated battery of tests on an understudied cancer population. Eligible participants will either be patients diagnosed with hematological malignancy (HM) or demographically matched healthy control patients. After HM diagnosis and treatment protocols have been established, patients will be inducted into the longitudinal study comprised of three visits: 1) after diagnosis but prior to chemotherapy treatment (baseline), 2) after one treatment cycle (one month post-baseline), and 3) after three treatment cycles (three months post-baseline). Patients will undergo a test battery designed to measure specific behavioral and neural mechanisms of attention; tests will either be computer-based cognitive tasks or simulated driving tests that immerse patients into virtual driving scenarios. During each test, EEG will be concurrently measured through non-invasive scalp electrophysiology recordings; EEG recordings will reveal underlying neural mechanisms affected by chemotherapy. Additionally, neuropsychological tests of vision, attention, and memory will be administered, as well as questionnaires to evaluate health, mobility, and life space. Finally, blood samples will be collected to examine levels of circulating inflammation-specific proteins typically present in cancer patients. This study will allow us to better understand the mechanisms through which chemotherapy influences cognitive performance. Results from this study will influence the administration of chemotherapy treatments so that patients can continue to receive the highest medical care while maintaining optimal cognitive abilities and quality of life.

Safety and Effectiveness of Donor γδT Cell Infusion to Prevent Relapsed/Refractory Leukemia Rescue Relapse After Allogeneic Hematopoietic Stem Cell Transplantation

This study will collect real-world safety and efficacy data from Japanese relapse/refractory chronic lymphocytic leukemia (CLL) and small lymphocytic leukemia (SLL) participants treated with venetoclax.

Acute leukaemia (AL) is an aggressive but potentially curable cancer that can affect women of childbearing age. When a pregnancy is complicated by a diagnosis of AL, clinicians face a complex dilemma: to balance risking the mother's survival through delaying treatment, against the potential harm to the foetus through exposure to cancer drugs. Reports suggest that, providing the first trimester is avoided, successful treatment of AL during pregnancy is possible, and considered safe. However, there is currently no standard approach to treatment of these women. This observational study aims to monitor and record the current treatment and outcomes of patients diagnosed with acute leukaemia during or prior to pregnancy. Patients will receive the treatment recommended by their doctor, the study will not alter the treatment pathway of participants. This study will establish a new research database of Leukaemia in Pregnancy, initially collecting data from cases since August 2009, and any new cases that are diagnosed during the current funding period. The initial planned analyses from this dataset will enable more robust, evidence-based recommendations to be made on how to monitor and manage these patients, and will add value to and improve the existing British Committee for Standards in Haematology (BCSH) guidelines, which were largely derived from expert opinion. This should enable healthcare professionals to have greater confidence in managing these patients, leading to a more standardised approach to providing high quality care. The study will benefit National Health Service (NHS) Trusts and patients across the United Kingdom (UK) through more informed clinical decision making with regards to the care they receive. It will also provide an important data resource which researchers can apply to use in further analyses, with plans to continue data collection if further funding is obtained.

The purpose of the study was to understand the effectiveness and safety of the study medicine called Inotuzumab ozogamicin (InO) in patients with B-cell ALL in whom the disease occurred again after the last treatment. This retrospective Study enroll adult patients who: were CD22 positive (a molecule in the body that stops the over activity of the immune system) Received only InO for the treatment of B-cell ALL that occurred again after the last treatment were Philadelphia chromosome positive (which occurs because of changes in genes) failed treatment with at least one Tyrosine Kinase Inhibitor (type of medicine that blocks the action of enzymes called tyrosine kinases which takes care of many cell functions, such as cell growth and division). The patient data except their personal details are collected from a hospital based electronic medical record in India. In this study the effectiveness and safety of InO will be studied after it was released to the market. To do that, the study aims to gather details of B-cell ALL patients from 7 -10 hospitals across India: in whom the disease occurred again or those who never showed any improvement to earlier treatments now being treated with InO alone Around 55 patients who have taken InO are likely to be enrolled in the study. Then by using a statistical model and with all the information gathered, the safety and effectiveness of InO will be decided.

Chronic myeloid leukaemia (CML) diagnosis is based on the demonstration of a BCR-ABL fusion transcript expressed by the Philadelphia (Ph) chromosome by RQ-PCR and/or the demonstration of t(9;22)(q34;q11) by conventional karyotyping or interphase FISH. As per standard practice, response to therapy is monitored using either molecular or cytogenetic tests or both; specifically, patients are monitored by quantitative PCR on peripheral blood, supplemented by bone marrow karyotyping if it was clinically indicated. ABL kinase mutational analysis is carried out when the transcript ratio has increased over two sequential samples or on clinical demand. Testing for T315I mutation is also performed for patients who fail to respond to first line TKI and all patients who acquire TKI resistance over the course of their treatment. Data collection is initiated six months after date of diagnosis; research nurses working to agreed operating procedures and data standards visit each of the 14 hospitals in the region and abstract a core clinical dataset from the patients' medical records. The information collected includes demographic details, baseline blood count data and first line treatment. All details are abstracted onto structured forms and entered onto the web-based system, which integrates Haematological Malignancy Research Network (HMRN) and Haematological Malignancy Diagnostic Service (HMDS) data. An important feature of data acquisition is the emphasis on primary source information; data from radiology reports, blood tests, clinical examination, and clinician summaries are recorded, enabling embedded algorithms in the database system to automatically generate stage and prognostic scores. Further data abstraction from the medical records has been undertaken to capture information on subsequent treatment lines. Information on date and cause of death were obtained from the National Health Service (NHS) Central Register.
