Filter by:This is a prospective,controlled and multi-institution trial.The aim is to identify if using decitabine and Arsenic Trioxide(ATO) as the therapy of Myelodysplastic Syndrome(MDS) has better relapse free survival and complete response than using decitabine alone. TP53 mutation is commonly associated with poor cancer patient prognosis yet no mutant p53 (mp53)-targeting regimen was clinically established. Particularly, p53 mutation is associated with extremely poor prognosis in myelodysplastic syndromes (MDS) and acute myeloid leukemia (AML) patients. Decitabine (DAC) is a FDA approved drug for MDS treatment. In two independent clinical trials reported recently, DNA demethylating drug DAC treatment yielded a surprisingly high rate of complete remission (CR) in mp53-harboring AML/MDS patients (Welch, NEJM, 2016; Chang, BJH, 2017). Notably, all of the mp53-expressing patients in the two clinical studies relapsed quickly. Arsenic trioxide (ATO) is a FDA approved drug for M3-AML treatment. Despite of the observed efficacy in treating non-APL patients, ATO is not yet approved for non-APL cancer treatment. ATO plays key role in regulating both wild-type p53 (wtp53) and mp53. Our published and unpublished data suggest ATO potentially hijacks nuclear iASPP-mediated STRaND pathway via exposing iASPP's RaDAR nuclear import code (Lu, Cancer Cell, 2013; Lu, Cell, 2014; Lu, Nat Rev Mol Cell Biol, 2016; Lu, unpublished). Our unpublished data also suggests a key role of ATO in regulating mp53 (Lu, The 17th International p53 Workshop, 2017). ATO is widely reported to be able to degrade and thus inhibit mp53's oncogenic function (Hamadeh, BBRC, 1999)(Liu, Blood, 2003). ATO suppressed cancer cell growth by targeting mp53 for degradation by Pirh2 degradation pathway (Yang, JBC, 2011; Yan, PLOS one, 2014); Here we explore the potential of combination of DAC and ATO in improving the mp53-harboring AML/MDS patients' relapse free survival (RFS) and the ability to thoroughly eliminate mp53 subclone. Basic researches aiming to explore the mechanisms how mp53 cells responds to DAC and/or ATO treatment and how mp53 cells develop resistance to DAC and/or ATO will be coupled. We designate trials aiming for a better treatment regimen for mp53 patients as 'PANDA-Trials'.
This is a phase II multi-institutional therapeutic study of a non-myeloablative T cell receptor (TCR) alpha/beta depleted haploidentical transplantation with post-transplant immune reconstitution using ALT-803 for the treatment of high-risk myeloid leukemia (AML), treatment-related/secondary AML, and myelodysplastic syndrome (MDS).
This study will use droplet digital PCR (ddPCR) method to quantify and track peripheral blood plasma mutant allele frequency (MAF) in MDS and AML patients before, during and after chemotherapy treatment. Quantification of MAF from fingersticks and saliva samples will also be performed to determine feasibility of obtaining adequate circulating tumor DNA (ctDNA) for ddPCR.
This pilot study evaluates safety of administration of red blood cell transfusions requested by patients based on their symptoms instead of levels of hemoglobin for the treatment of chronic anemia in patients with blood disorders.
Chronic Graft Versus Host Disease (GVHD) is one of the most challenging complications in long term survivors of allogeneic stem cell transplantation. As the number of allogeneic stem cell transplantations rises annually, the incidence of chronic GVHD rates have also increased due to a variety of factors including but not limited to increasing use of peripheral blood stem cell (PBSC) grafts, increasing age of both donors and recipients, and increased use of matched unrelated donors. One study showed much lower than traditional acute GHVD rate and chronic GHVD which is similar with historical rates when atorvastatin was administered prophylactically to both the donors as well as recipients of matched related allogeneic stem cell transplantation, lead to the interest in further examining the role of Atorvastatin in relation to the development of GVHD. The investigator hypothesize that the administration of atorvastatin in recipients of matched unrelated allogeneic stem cell transplantation, a group with known higher incidence of chronic GHVD, would be a safe and effective method to reduce the incidence of chronic GVHD. Matched related allogeneic stem cell transplantation recipients will not be included in this study due to their significantly lower GVHD rates. The definition and monitoring of our primary endpoint of GVHD is well established in clinical trials in allogeneic stem cell transplantations and the investiagor will utilize the National Institutes of Health (NIH) Staging System for the diagnosis and severity assessment of chronic GVHD as well the recommendations from the NIH Consensus Conference for the conduct of clinical trials in chronic GVHD. Several secondary endpoints will be examined as defined below and include standard complementary data in the examination of clinical trials in chronic GVHD again as laid out by the NIH Consensus Conference for conduct of clinical trials in chronic GHVD.
This is a Phase 2a, Open-label, one arm study in which the eligible patients will be treated with IV Nerofe, three times a week in 28 days cycles (up to 12 cycles). Evaluation will include safety procedures, blood level of study drug in certain time points, immune system response and tests checking the mechanism of the drug action.
This is a phase I study designed to assess the maximum tolerated dose (MTD) of pyrimethamine and provide the recommended Phase 2 dose (RP2D) for the treatment of intermediate/high-risk MDS that is refractory to or relapsed after treatment with azanucleosides.
The primary objective of the Phase Ib study is to determine the dose-limiting toxicity (DLT) and maximal tolerated dose (MTD) of BP1001 in combination with dasatinib in patients with with Philadelphia Chromosome Positive (Ph+) Chronic Myelogenous Leukemia (CML) including chronic phase patients who have failed initial tyrosine kinase inhibitor (TKI) therapy, accelerated or blast phase, Ph+ Acute Myeloid Leukemia (AML) or High-risk Ph+ Myelodysplastic Syndrome (MDS). The primary objective of the Phase IIa study is to assess the efficacy of the combination of BP1001 and dasatinib in patients with Ph+ CML, Ph+AML, or high-risk Ph+ MDS.
The purpose of this study is to determine the safety and establish the maximum tolerated dose (MTD) of omacetaxine in combination with azacitidine and G-CSF in patients with relapsed and/or refractory MDS.
The goal of Part 1 of this clinical research study is to learn if ponatinib alone can help to control FLT3-mutated AML or FLT3-mutated high-risk MDS. The safety of this drug will also be studied. The goal of Part 2 of this clinical research study is to find the highest tolerable dose of ponatinib in combination with 5-azacytidine and to learn if the highest dose level found can help to control FLT3-mutated AML or FLT3-mutated high-risk MDS. The safety of this combination will also be studied.
