Role of PTK-7 in Acute Myeloid Leukemias
Acute Myeloid LeukemiaThe pseudo tyrosine kinase receptor 7 (PTK7) is an orphan tyrosine kinase receptor assigned to the planar cell polarity pathway. PTK7 is expressed in normal myeloid progenitors and CD34(+) CD38(-) bone marrow cells in humans. It is also expressed in acute myeloid leukemia (AML) and is mostly assigned to granulocytic lineage differentiation. In AML, PTK7 seems to convey promigratory and antiapoptotic signals into the cell and represents an independent prognosis factor of survival in patients treated with induction chemotherapy. This study aims at: evaluating the impact of PTK7 expression on primary AML cells ex vivo evaluating the diagnostic and prognostic value of a soluble form of PTK7
Studying Biomarkers in Cell Samples From Patients With Acute Myeloid Leukemia
LeukemiaRATIONALE: Studying samples of tissue from patients with cancer in the laboratory may help doctors learn more about changes that occur in DNA and identify biomarkers related to cancer. PURPOSE: This research study is looking at biomarkers in cell samples from patients with acute myeloid leukemia.

Long Term Therapy With Imatinib: Development of Late Side Effects and Compliance to Treatment
Chronic Myeloid LeukemiaNewly DiagnosedImatinib has revolutionised the treatment of chronic myeloid leukaemia (CML). The first clinical trials were conducted in 1998 in patients with advanced disease, and by 2002 imatinib was established as the standard therapy for all patients including those recently diagnosed. In spite of overwhelming evidence about its efficacy we still need to gain more knowledge about issues related to long term treatment with imatinib such as why some patients respond better than others, the development of side effects and the quality of life.
Symptom-Related Cytokines in Acute Myeloblastic Leukemia and Myelodysplastic Syndrome Patients
Myelodysplastic SyndromeAcute Myeloblastic Leukemia1 morePrimary Objective: 1. To assess the self-reported symptoms and the plasma cytokine levels of AML/MDS patients pretransplantation and posttransplantation with allogeneic blood and marrow in order to identify changes in symptoms (or symptom clusters) and changes in cytokines that may be related to the conditioning regimen and/or to the development of GVHD during the 100 days posttransplant. Based on the current literature, both animal and human research, in this study we hypothesize that increases in TNF alpha to be associated with poor appetite, sleep disturbance and fatigue, but not with increases in pain, depression and numbness.
Study to Evaluate Chronic Myeloid Leukemia Treatment Landscape and Real-life Treatment Outcomes...
Chronic Myeloid LeukaemiaThe objectives of this study are to describe patient demographics, clinical and disease characteristics and treatment patterns of Chronic Lymphoid Leukaemia (CML) in Hungary. The primary endpoint of this study is the overall survival of CML patients treated with tyrosine kinase inhibitors in Hungary. The Overall Survival (OS) of all enrolled patients, OS by sequence pattern and by the number of treatment lines will be analyzed. Secondary objectives are description of the treatment length in 1st and later lines, incidence and prevalence of CML, the patient demographics (as age, gender, comorbidities), average number of patients' comorbidities, most frequent comorbidities and patient number with comorbidities at baseline and at different treatment lines by investigated Thyrosine Kinase Inhibitor (TKI), distribution of the investigated TKI therapies by treatment lines
Ex-vivo Primed Memory Donor Lymphocyte Infusion to Boost Anti-viral Immunity After T-cell Depleted...
Acute Myeloid LeukemiaHigh Risk Acute Myeloid Leukemia6 moreHSCT from an allogeneic donor is the standard therapy for high-risk hematopoietic malignancies and a wide range of severe non-malignant diseases of the blood and immune system. The possibility of performing HSCT was significantly limited by the availability of donors compatible with the MHC system. However, modern ex-vivo and in vivo technologies for depletion of T lymphocytes have made it possible to improve the outcomes of HSCT from partially compatible related (haploidentical) donors. In representative groups, it was shown that the success of HSCT from haploidentical donors is not inferior to standard procedures of HSCT from HLA-compatible unrelated donors. HSCT from haploidentical donors in children associated with the deficit of the adaptive immune response, which persists up to 6 months after HSCT and can be an increased risk of death of the patient from opportunistic infections. To solve this problem, the method of infusion of low doses of donor memory T lymphocytes was introduced. This technology is based on the possibility of adoptive transfer of memory immune response to key viral pathogens from donor to recipient. Such infusions have been shown to be safe and to accelerate the recovery of the pathogen-specific immune response. The expansion of virus-specific T lymphocytes in the recipient's body depends on exposure to the relevant antigen in vivo. Thus, in the absence of contact with the viral antigen, the adoptive transfer of memory T lymphocytes is not accompanied in vivo by the expansion of virus-specific lymphocytes and does not form a circulating pool of memory T lymphocytes, that can protect the patient from infections. Therefore the investigators assume that ex-vivo priming of donor memory lymphocytes with relevant antigens can provide optimal antigenic stimulation and may solve the problem of restoring immunological reactivity in the early stages after HSCT. Technically ex-vivo primed memory T lymphocytes will be generated by short incubation of CD45RA-depleted fraction of the graft (a product of T lymphocyte depletion) with a pool of GMP-quality peptides representing a number of key proteins of the viral pathogens. The following are proposed as targeted antigens: CMV pp65, EBV EBNA-1, EBV LMP12A, Adeno AdV5 Hexon, BKV LT, BKV VP1. An infusion of donor memory lymphocytes will be performed on the day +1 after transplantation. Parameters of the assessment will be safety and efficacy (immune response by day 60 and stability (responses by day 180).

A Study of the Effectiveness of Venetoclax Tablets in Adult Acute Myeloid Leukemia Participants...
Acute Myeloid Leukemia (AML)Acute Myeloid Leukemia (AML) is a cancer of the blood and bone marrow and is the most common acute leukemia in adults. This study will evaluate how well Venetoclax works to treat AML in adult participants who are ineligible for standard induction therapy in Russian Federation. Venetoclax is a drug approved to treat Acute Myeloid Leukemia. All study participants will receive Venetoclax as prescribed by their study doctor in accordance with approved local label. Adult participants with a diagnosis of AML who are ineligible for standard induction therapy will be enrolled. Around 50 participants will be enrolled in the study in approximately 15 sites in Russian Federation. Participants will receive venetoclax tablets to be taken by mouth daily according to the approved local label. The duration of the study is approximately 18 months. There is expected to be no additional burden for participants in this trial. All study visits will occur during routine clinical practice (approximately every 3 months) and participants will be followed for 18 months.
