This study will collect tumor samples from people with cancers of the blood, bone marrow, or lymph glands for laboratory study of the biology of these conditions. Such studies contribute to a better understanding of cancer biology and to the development of new treatments. Planned studies include: * Examination of individual cancer cells and to search for differences compared to other types of cancer and normal cells * Examination of the chromosomes and genes in cancer cells and to search for differences compared to other types of cancer and normal cells * Development of sensitive methods to detect small amounts of cancer that remain after treatment * Search for new cancer proteins that might serve as targets for treatment * Investigation of methods to develop cancer vaccines. Patients from \>= 1 to 75 years of age with acute lymphocytic leukemia, acute myelogenous leukemia, myelodysplastic syndrome, chronic myelogenous leukemia, juvenile myelomonocytic leukemia, non-Hodgkin's lymphoma, Hodgkin's disease, and other hematologic malignancies may be eligible for this study. Blood or bone marrow samples will be collected when sampling is required for the patient's medical care. Cells from some individuals will be grown in test tubes, establishing cell lines or in animals, establishing xenograft models. (A xenograft is transplantation of cells of one species to another species.)
NCT06656494
Evaluate the safety, tolerability, pharmacokinetics, and preliminary efficacy of ICP-248 in combination with azacitidine in patients with acute myelogenous leukemia and Myelodysplastic Syndromes.
NCT01366612
This is a single institution study of fludarabine and busulfan versus fludarabine, busulfan and low dose total body irradiation in patients undergoing allogeneic stem cell transplantation. A study population of 80 subjects will be enrolled from The John Theurer Cancer Center at Hackensack University Medical Center. Subjects who are eligible to receive allogeneic hematopoietic stem cell transplantation according to the eligibility criteria will be consented and enrolled. Subjects will be randomly assigned to receive one of 2 conditioning regimen: fludarabine and busulfan, or fludarabine busulfan and low dose total body irradiation (TBI). Subjects will be followed until 1 year post transplantation to assess the relapse rate in each arm and transplant-related toxicity. The combination of fludarabine and busulfan is the current standard of care for patients with myeloid malignancies (AML, CML and other myeloproliferative disorders, or MDS) undergoing allogeneic transplantation at HUMC. In this study we will be comparing in a randomized fashion the standard regimen to a regimen of fludarabine, busulfan and TBI.
NCT06859424
The purpose of this clinical trial is to compare drug combinations to learn which drugs work best to prevent graft-versus-host-disease (GVHD) in people who have received a stem cell transplant. The source of stem cells is from someone who is not related and has a different blood cell type than the study participant. The researchers will compare the new drug combination to a standard drug combination. They will also learn about the safety of each drug combination. Participants will: * Receive the standard or new drug combination after transplant * Visit the doctor's office for check-ups and tests after transplant that are routine for most transplant patients * Take surveys about physical and emotional well-being * Give blood and stool samples.

NCT02091245
This research study involves participants who have acute lymphoblastic or acute myelogenous leukemia that has relapsed or has become resistant (or refractory) to standard therapies. This research study is evaluating a drug called KPT-330. Laboratory and other studies suggest that the study drug, KPT-330, may prevent leukemia cells from growing and may lead to the destruction of leukemia cells. It is thought that KPT-330 activates cellular processes that increase the death of leukemia cells. The main goal of this study is to evaluate the side effects of KPT-330 when it is administered to children and adolescents with relapsed or refractory leukemia.
NCT07254312
Venetoclax (VEN) is a potent and selective oral inhibitor of the BCL-2 gene and has shown anti-leukemic activity when used in combination with hypomethylating agents (HMA) in patients with Acute Myeloid Leukemia (AML), both newly diagnosed and in relapse or refractory (R/R) stages. A daily dose of 400 mg has shown the best results in terms of efficacy, toxicity, and low early mortality rates (DiNardo et al., Blood 2019). The HMA-VEN combination has been approved for the treatment of newly diagnosed AML patients who are not candidates for intensive therapy. However, although this treatment is considered low-intensity, it causes a non-negligible toxicity profile, especially hematological toxicity, even in patients who have already achieved remission. As a result, treatment often needs to be interrupted, and VEN dosage adjusted in subsequent cycles. An analysis by Pratz et al. (Pratz et al., Am J Hematol 2022) following the publication of the pivotal trial reported grade IV cytopenias lasting at least 7 days in the cycles following remission in 161 (87%) patients in the VEN+Azacitidine arm. Furthermore, plasma concentrations of VEN were analyzed in patients who developed grade IV cytopenias for at least 7 days, and no correlation was found between VEN plasma levels and the number of observed cytopenias. In the routine management of these patients, when hematologic toxicity occurs, the approach varies greatly from center to center and is based on the individual experience and assessment of the referring clinician. As a result, there is no standardized approach. Plasma concentrations of VEN are not routinely measured during treatment. A better understanding of the factors determining the variable toxicity observed in patients in remission could optimize treatment to improve patient tolerability and allow for the regular administration of therapy, which is essential for maintaining leukemia remission status.
NCT07254611
Acute Myeloid Leukemia requires intensive chemotherapy treatment, usually followed by an allogeneic bone marrow transplant to reduce the risk of relapse. However, in elderly patients, intensive treatment is often not a feasible option due to the high toxicity, which limits its use. Recently, a combination of hypomethylating agents (HMAs, 5-azacitidine or decitabine), which have a low toxicity profile, and venetoclax, a potent inhibitor of the anti-apoptotic protein Bcl2, has been approved for patients with Acute Myeloid Leukemia who are not candidates for intensive therapy. This combination has shown a significant survival advantage compared to the use of HMA alone (Di Nardo, NEJM 2020). Even in the difficult setting of relapsed/refractory patients, the combination of venetoclax with an HMA agent has led to high rates of global response and good-quality response (global responses 64%, of which 50% were complete responses or with incomplete hematopoietic recovery), as well as disease-free survival rates of 8.9 months for responsive patients, offering many the option for allogeneic transplantation (Aldoss, Haematologica 2018). However, the venetoclax-HMA combination is associated with hematological toxicity, characterized by deep and prolonged cytopenias, particularly in non-responsive diseases but also after achieving complete remission. Therefore, the risk of infection during periods of severe neutropenia is high. For this reason, although the need for infection prophylaxis in this therapeutic regimen is not yet well defined, it is common practice to administer antifungal prophylaxis with posaconazole, at least during the first two months of therapy or until neutropenia resolves. Posaconazole has been shown to reduce fungal complications during treatment for active Acute Leukemia stages. An increased incidence of invasive fungal infections has been reported in patients with active disease (refractory or at diagnosis). However, this choice must take into account the pharmacological interactions with venetoclax, as posaconazole is a strong inhibitor of cytochrome P3A4 activity and may reduce venetoclax metabolism, thus increasing its plasma levels. To avoid excessive toxicity from venetoclax, its dosage must be adjusted. Pharmacokinetic studies have shown that during prophylaxis therapy with posaconazole, treatment with venetoclax at doses of 50 or 100 mg was well tolerated. Therefore, based on the increased plasma levels of venetoclax, it is recommended that its dosage be reduced by at least 75% compared to the full dose (Agarwal, Clin Ther 2017). The available pharmacokinetic studies evaluating venetoclax plasma levels in combination with posaconazole only consider levels after venetoclax has reached steady state (Agarwal, Clin Ther 2017). However, it is known that co-administration can alter venetoclax concentrations until a stable plasma level of posaconazole is reached. During this period, it is important to monitor venetoclax levels closely in order to adjust the dosage and avoid excessive exposure to the drug, thus reducing the risk of increased toxicity, but without excessively lowering plasma levels, which could compromise the treatment's efficacy.
NCT02143830
The purpose of this study is to determine whether the use of lower doses of busulfan and the elimination of cyclosporine will further reduce transplant-related side effects for patients with Fanconi Anemia (FA). Patients will undergo a transplant utilizing mis-matched related or matched unrelated donors following a preparative regimen of busulfan, fludarabine, anti-thymocyte globulin and cyclophosphamide.

NCT06911710
This study is an open, single-arm, prospective, Phase I/II clinical study using "3+3" dose escalation and dose expansion to investigate the safety, maximum tolerated dose, in vivo pharmacokinetic profile, and preliminary efficacy of CAR-T cell injections for the treatment of relapsed/refractory malignant hematological neoplasms in subjects.
NCT06899581
The purpose of this study is to observe the impact leukaemia treatment has on gut health (microbiomes) and how quickly the gut health recovers after leukamia treatment. The gut microbiome has a number of important functions not only in the gut but within the whole body. Changes to your child's nutritional status throughout treatment may affect how well they recover from treatment. This study will monitor the impact of feeding and nutrition on nutritional status and gut health in young people undergoing treatment for leukaemia. The measurements needed to observe nutritional and gut microbiomes will occur when your child attends their routine medical appointments at Great Ormond Street Hospital. Medical treatment uses chemicals to kill leukaemia cells. The type of medications used in the treatment of leukaemia can damage the gut resulting in inflammation call mucositis. This stops the gut from working and sometimes nutrition has to be provided via a feeding tube or intravenous. Chemotherapy, mucositis and intravenous nutrition all have an impact on the gut. Little is know how the gut health recovers after treatment for leukaemia. This will be the first study to specifically monitor the impact of feeding and nutritional on gut health in children undergoing treatment for leukaemia. By understanding what changes are occurring to your child's nutritional status and gut halth during treatment and during recovery will help to develop guidelines for healthcare professionals to support optimal gut health recovery.
NCT06835140
The goal of this clinical trial is to evaluate the effectiveness of CD123-CD16 bispecific antibody-modified NK cells in treating patients with CD123-positive relapsed or refractory Acute Myeloid Leukemia (RR AML). It will also assess the safety of this modified NK cell therapy. The main questions： Does the infusion of CD123-CD16 bispecific antibody-modified NK cells induce remission in RR AML patients? What are the safety and potential adverse effects associated with the administration of these modified NK cells? Researchers will administer CD123-CD16 bispecific antibody-modified NK cells to RR AML patients and compare the outcomes to existing treatment options to determine efficacy and safety. Participants will: Undergo lymphocyte-depleting chemotherapy Fludarabine\&Cyclophosphamide from day -5 to day -3 before NK cell infusion. Receive intravenous infusions of modified NK cells at escalating doses: The first three patients will receive 1×10⁷ cells/kg. The next three patients will receive 2×10⁷ cells/kg. The final three patients will receive 4×10⁷ cells/kg. Have NK cell infusions administered every 96-120 hours for a total of three infusions, with each infusion completed within 10 to 15 minutes. Undergo dose escalation with subsequent groups only after confirming the safety of the previous dose group. Have their vital signs (temperature, heart rate, respiratory rate, blood pressure, etc.) monitored before and after each infusion. Keep baseline data records during NK cell infusions. Participate in follow-up assessments to monitor disease remission and detect any adverse events. This trial aims to provide new treatment options for RR AML patients by leveraging the targeted cytotoxic effects of CD123-CD16 bispecific antibody-modified NK cells to achieve disease remission.
