Start date: January 1, 2012
Phase:
Study type: Observational

The goal of this observational study is to evaluate the epidemiological and clinical-pathological features of Philadelphia-negative myeloproliferative neoplasms through data from medical records

NCT ID: NCT05400122 Recruiting - Colorectal Cancer Clinical Trials

Natural Killer (NK) Cells in Combination With Interleukin-2 (IL-2) and Transforming Growth Factor Beta (TGFbeta) Receptor I Inhibitor Vactosertib in Cancer

Start date: September 9, 2022
Phase: Phase 1
Study type: Interventional

One of the ways that cancer grows and spreads is by avoiding the immune system.NK cells are immune cells that kill cancer cells, but are often malfunctioning in people with colorectal cancer and blood cancers. A safe way to give people with colorectal cancer and blood cancers fresh NK cells from a healthy donor has recently been discovered. The purpose of this study is to show that using two medicines (vactosertib and IL-2) with NK cells will be safe and will activate the donor NK cells. NK cells and vactosertib are experimental because they are not approved by the Food and Drug Administration (FDA). IL-2 (Proleukin®) has been approved by the FDA for treating other cancers, but the doses used in this study are lower than the approved doses and it is not approved to treat colorectal cancer or blood cancers.

NCT ID: NCT04992949 Recruiting - Clinical trials for Acute Myeloid Leukemia

Evaluation of CPX-351 Monotherapy in Acute Myeloid Leukemia Secondary to Myeloproliferative Neoplasm

CPX-351 TA-SMP
Start date: March 23, 2022
Phase: Phase 2
Study type: Interventional

The three classic myeloproliferative neoplasms (MPNs) include polycythemia Vera (PV), essential thrombocythemia (ET) and primary myelofibrosis (PMF). The natural history of these MPNs is the possible progression to acute myeloid leukemia (MPN-blast phase) at variable percentage depending the entity. Leukemic transformation of MPN occurs in 8% to 23% of primary myelofibrosis (PMF) patients in the first 10 years after diagnosis and in 4% to 8% of polycythemia vera (PV) and essential thrombocytosis (ET) patients within 18 years after diagnosis. The risk for leukemic transformation is increased by exposure to cytotoxic chemotherapy. The molecular pathogenesis of MPN-blast phase remains an area of active research. The prognosis of blast phase MPNs is very poor : approximately 50% of the patients are deemed eligible for intensive treatment (ie. conventional induction chemotherapy regimen with anthracyclines and cytarabine). The patients who are not fit for such intensive treatment approach due to age or comorbidities, are treated with Hypomethylating agents, low dose palliative chemotherapy, or supportive care. Nevertheless, there is a need for more effective and better tolerated treatment approaches in order to increase the response rate and hence, the transplant rates which should translate into improved survival. CPX-351 is a new formulation of cytarabine and daunorubicin encapsulated at a fixed 5:1 molar-ratio in liposomes that exploits molar ratio-dependent drug-drug synergy to enhance antileukemic efficacy. Based on similarities between post-myelodysplastic syndrome (MDS) and post-MPN secondary AML in terms of disease resistance to chemotherapy, of fragile patient profile, The hypotheses made is that CPX-351 may improve the results of induction chemotherapy without increasing its toxicity and therefore may increase the proportion of patients who could benefit from an allogeneic Stem Cell Transplantation (SCT).

NCT ID: NCT04968834 Recruiting - Leukemia Clinical Trials

Protocol For Genomically Profiling, Collecting, Archiving And Distributing Blood And Bone Marrow Specimens From Children And Young Adults With Hematologic Malignancy

Start date: June 11, 2021
Phase:
Study type: Observational [Patient Registry]

This research study is a genomic profiling and repository study for children and young adults who have leukemia, myelodysplastic syndrome (MDS) or myeloproliferative syndrome (MPS). Genes are the part of cells that contain the instructions which tell cells how to make the right proteins to grow and work. Genes are composed of DNA letters that spell out these instructions. Genomic profiling helps investigators understand why the disease develops and the instructions that led to its development. Understanding the genetic factors of the disease can also help investigator understand why the disease of some people can respond to certain therapies differently than others. The genomic profiling will be performed using bone marrow and blood samples that either have already been obtained during a previous clinical procedure or will be obtained at the time of a scheduled clinical procedure. Studying the genetic information in the cells of these samples will provide information about the origin, progression, and treatment of leukemia and myeloproliferative syndromes and myelodysplastic syndrome. Storing the bone marrow and blood samples will allow for additional research and genomic assessments to be performed in the future.

NCT ID: NCT04935684 Recruiting - Clinical trials for Myelodysplastic Syndromes

Faecal Microbiota Transplantation After Allogeneic Stem Cell Transplantation

TMF-Allo
Start date: December 20, 2022
Phase: Phase 2
Study type: Interventional

The aim of this study is to assess the Fecal Microbiota Transplantation (FMT) efficacy in the prevention of allogeneic hematopoietic stem cell transplantation (allo-HSCT) complications and particularly Graft versus Host Disease (GvHD). The hypothesis of this study is that allogeneic FMT may improve outcomes of these patients.

NCT ID: NCT03907436 Completed - Myelofibrosis Clinical Trials

NUTRIENT
Start date: October 1, 2018
Phase: N/A
Study type: Interventional

The purpose of this study is to determine whether MPN patient are able to adhere to a dietary intervention. Participants will be randomized to one of two healthy diets. Participants will receive in person dietician counseling and online curriculum. Adherence will be measured using online surveys and phone diet recalls. Changes in inflammatory markers in blood will also be measured at 5 time points during this 15 week study.

NCT ID: NCT03852407 Recruiting - Multiple Myeloma Clinical Trials

Allogeneic Hematopoietic Cell Transplantation From HLA-matched Donor After Flu-Mel-PTCy Versus Flu-Mel-ATG Reduced-intensity Conditioning

HLA
Start date: February 4, 2019
Phase: Phase 2
Study type: Interventional

The present project aims at comparing two conditioning regimens (FM-PTCy vs FM-ATG). The hypothesis is that one or the two regimens will lead to a 2-year cGRFS rate improvement from 30% (the cGRFS rate with FM without ATG/PTCy) to 45% (Pick-a-winner phase 2 randomized study).

NCT ID: NCT02873832 Completed - Clinical trials for Myeloproliferative Syndrome

Efficacy of Heat-shock Protein (HSP) Inhibitors in Myeloproliferative Syndromes (MPS)

HSP-SMP
Start date: January 2015
Phase: N/A
Study type: Observational

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.

NCT ID: NCT02508038 Recruiting - Clinical trials for Acute Myeloid Leukemia

NCT ID: NCT02129582 Completed - Multiple Myeloma Clinical Trials

Targeted Marrow Irradiation, Fludarabine Phosphate, and Busulfan Before Donor Progenitor Cell Transplant in Treating Patients With Hematologic Malignancies

Start date: November 5, 2014
Phase: Phase 1
Study type: Interventional

This phase I trial studies the side effects and best dose of targeted marrow irradiation when given with fludarabine phosphate and busulfan before donor progenitor cell transplant in treating patients with hematologic malignancies. Targeted marrow irradiation is a type of specialized radiation therapy that delivers a high dose of radiation directly to the cancer cells, which may kill more cancer cells and cause less damage to normal cells. Giving targeted marrow irradiation and chemotherapy drugs, such as fludarabine phosphate and busulfan, before a donor progenitor cell transplant may help stop the growth of cancer cells. It may also stop the patient's immune system from rejecting the donor's progenitor cells. When the healthy progenitor cells from a donor are infused into the patient they may help the patient's bone marrow make progenitor cells, red blood cells, white blood cells, and platelets.
