The Main purpose of this project to study the uptake pattern of FLT-PET and it is value in assessing the malignant hematopoiesis in MPN within the pediatric age group, in terms of diagnosis, staging and monitoring response to therapy. As well as, evaluating FLT-PET as a novel non-invasive technique in cases with MPN and its role in comparison to the standard bone marrow biopsy with regard to disease diagnosis, assessment of disease activity, detection of transformation, monitoring of treatment response and grading of fibrosis.Furthermore, we aim to study the association of FLT-PET uptake patterns with different genetic makeup (JAK2, CALR positive, MPL, or Triple negative disease) or allele burden in cases of Pre-PMF with the ability of FLT-PET to differentiate between Pre-PMF and ET. Although MPNs are diseases of elderly, MPN is diagnosed in younger age groups in a considerable number of cases. Since most of the available data as well as current WHO classification criteria emphases on the "average" MPN patients who range in age between 55 and 65 years. Less consistent data are available in the groups of patients presenting below this median age, such as children and younger adults which we're planning to reveal.
- This is an open label single-arm, single-institution stud to evaluate the efficacy and safety of SGI-110 in Philadelphia chromosome negative (Ph-) Myeloproliferative Neoplasms (MPN) (excluding PV, ET and primary/secondary myelofibrosis). The study will enroll approximately 50 patients at the Weill Cornell Medical College. - Enrollment onto this clinical study is expected to be completed in approximately 36 months. The total study duration will depend on individual response, evidence of disease progression and tolerance. Participants will be followed monthly for six months after removal from study or until death, whichever occurs first. Key eligibility: - Confirmed diagnosis of Ph- MPN and had - No chemotherapy or radiation treatment within 2 weeks prior to study entry. - Subjects meet other protocol-defined criteria related to baseline screening procedures.
The main purpose of this study is to determine the safe and recommended dose of APR-246 in combination with azacitidine as well as to see if this combination of therapy improves overall survival.
The purpose of this study is to test the effectiveness of a drug called pembrolizumab in patients with Myeloproliferative Neoplasm (MPN); chronic phase (MF-CP), accelerated phase (MPN-AP), or blast phase (MF-BP). Myelofibrosis neoplasm (MPN) is a group of diseases of the bone marrow in which excessive cells are produced. Pembrolizumab also known as Keytruda is a drug that has recently been approved in the United Stated by the Food and Drug Administration (FDA) for the treatment of patients with unresectable or metastatic melanoma and disease progression. Pembrolizumab is experimental in the treatment of MPN. The researchers want to find out what effects, good and /or bad it has on participants and the disease. Participants qualify to take part in this research study if have been diagnosed with a MPN blood disorder called myelofibrosis (MF). Accelerated (10-19% blasts in the blood or bone marrow) and blast phase (>20% blasts in the blood or bone marrow) MPN has been a difficult disease to treat. The term "blasts" refers to immature cells found in the bone marrow. They are not fully developed, and therefore, do not yet carry out any particular function within the body. Funds for conducting this research are provided by Merck and Company, the manufacturer of the study drug pembrolizumab.
The purpose of this study is to evaluate the efficacy and safety of pemigatinib (INCB054828) in subjects with myeloid/lymphoid neoplasms with fibroblast growth factor receptor (FGFR) 1 rearrangement.
This pilot phase I trial studies the side effects of engineered donor stem cell transplant in treating patients with hematologic malignancies. Sometimes the transplanted cells from a donor can make an immune response against the body's normal cells (called graft-versus-host disease). Using T cells specially selected from donor blood in the laboratory for transplant may stop this from happening.
The purpose of this prospective, longitudinal, noninterventional study is to describe clinical characteristics, evolution of disease burden, and treatment patterns in patients with select subcategories of essential thrombocythemia (ET) or myelofibrosis (MF).
This phase II trial studies how well tacrolimus, bortezomib, and anti-thymocyte globulin (thymoglobulin) work in preventing low toxicity graft versus host disease (GVHD) in patients with blood cancer who are undergoing donor stem cell transplant. Tacrolimus and anti-thymocyte globulin may reduce the risk of the recipient's body rejecting the transplant by suppressing the recipient's immune system. Giving bortezomib after the transplant may help prevent GVHD by stopping the donor's cells from attacking the recipient. Giving tacrolimus, bortezomib, and anti-thymocyte globulin may be a better way to prevent low toxicity GVHD in patients with blood cancer undergoing donor stem cell transplant.
Heat-shock proteins (HSP) have been very highly conserved throughout the evolution of species and are characterized by their chaperone function, thanks to their ability to prevent aggregation and to promote the renaturation/break down of damaged proteins. Among other targets, they also chaperone JAK2, a key step that is deregulated in signalling in myeloproliferative syndromes (MPS) because of the JAK2V617F mutation. These HSP also have a potent cytoprotective action through their multiples inhibiting effects on apoptotic processes. Little is known about levels of HSP expression, in particular for HSP70 and HSP27, in MPS cells. However, in vitro studies of different cell models have shown the interest of HSP90 inhibitors in slowing cell proliferation in MPS. These results have been confirmed in animal models with results in terms of blood counts and overall survival. In addition, it seems that the V617F mutated form of JAK2 is more sensitive than the wild-type to HSP90 inhibitors. Finally, inhibitors of HSP90 remain efficacious with regard to the inhibition of cell growth, even in cases of resistance to JAK2 inhibitors. Nonetheless, HSP90 inhibitors are known to stimulate the expression of other HSP, notably HSP27 and HSP70, which are, through their properties, tumorigenic and could lead to an escape phenomenon. Thus the combined use of several HSP inhibitors could be beneficial, and eventually present synergistic effects on the inhibition of tumour processes.
