Filter by:Acute myeloid leukemia (AML) is a genetically heterogeneous disease and allogeneic hematopoietic stem cell transplantation (allo-HSCT) is a curative treatment option for AML except for AML-M3. Relapse remains the major cause of treatment failure after allo-HSCT. Molecular residual disease has been shown to be a strong risk factor for relapse after HSCT. In this study, the investigators will detect mutations before/after allo-HSCT by using next-generation sequencing (NGS) technique to measure residual disease and evaluate the prognostic impact of molecular residual disease in a cohort of AML participants receiving allo-HSCT.
The MAC-HAPLO-MUD trial is a randomized prospective phase III trial comparing HLA 10/10 matched unrelated donor and haploidentical allogeneic hematopoietic stem cell transplantation after myeloablative conditioning regimen in patients, age 15 years or older, with Acute Myeloid Leukemia (AML) or Acute Lymphoblastic Leukemia (ALL) or Myeloproliferative Syndrome (SMP) or Myelodysplastic Syndromes (SMD) and requiring allogeneic hematopoietic stem cell transplantation. Primary endpoint is the 1-year progression free survival without acute grade II-IV GvHD and without moderate and severe chronic GvHD.
Allogeneic hematopoietic stem cell transplantation (Allo-HSCT) is a curative option for patients with acute myeloid leukemia (AML). However, transplantation related toxicity and mortality as well as the existence of HLA identical sibling donor represent major limitations. Over the 20 past years, the development of reduced intensity conditioning (RIC) regimen and the use of alternative donors allowed extending the possibility of Allo-HSCT for AML, with decreased toxicity and mortality. This invited to propose this strategy to more advanced patients, making that AML recurrence has become one of the main issues after Allo-HSCT. Thus, to develop prophylactic and preemptive strategies to minimize disease recurrence after Allo-HSCT is now the main challenge in the field. Among cellular and/or pharmacological treatments after Allo-HSCT, donor lymphocyte infusion (DLI) is probably one of the most commonly used treatments after Allo-HSCT. Indeed, DLI were reported as a potential efficient immunotherapy more than 20 years ago for the treatment of patients with leukemia relapsing after Allo-HSCT. However, most of experiences were reported in the setting of relapse after Allo-HSCT and no prospective evaluation of prophylactic DLI is available so far. Thus no strong recommendation for the use of DLI after Allo-HSCT can be made. Our study proposal would like to assess the question of prophylactic DLI efficacy, as a proof of concept of early immune intervention after Allo-HSCT. The investigators, therefore, designed a prospective multicenter randomized trial evaluating the impact of early DLI on outcome after Allo-HSCT for AML.
High risk MDS (Myelodysplastic Syndrome) patients will be treated with SGI-110 after Allogeneic Stem Cell Transplantation in the hypothesis that SGI-110 maintenance given early after HSCT can prevent relapse without increasing non-relapse mortality translating in an improved disease-free survival.
This is a prospective,uncontrolled and multi-institution trial.The aim is to identify if using decitabine,cytarabine and ATO as the therapy of acute myeloid leukemia(AML) with p53 mutations has better relapse free survival and complete response than using decitabine and cytarabine. 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'.
Prospective multicenter, open-lab el, observational, single arm study of decitabine. Subjects will be elderly patients with newly diagnosed, treatment-naïve AML who are unfit to receive and not candidate for intensive induction chemotherapy (iIC)
The purpose of this study is to determine whether deferasirox is effective in the treatment of acute lymphatic leukemia (ALL) and acute Myeloid leukemia (AML).
The purpose of this study is to elucidate the role of RUNX1 in Acute Myeloid Leukemia (AML), in particular, the transcriptional regulation of genes by mutated forms of this protein. This research will study the effect of mutations found in AML patients
The prognosis of elderly patients with relapsed or refractory acute myeloid leukemia (AML) is grave. Because of their chronological age and/or the presence of multiple co-morbidities, treatment-related mortality in elderly patients with AML is quite high although higher intensive treatment is mandatory to overcome chemoresistant characteristic of their disease. Several regimens have been evaluated as salvage chemotherapy for relapsed or refractory AML such as Mitoxantrone/High dose Cytarabine or Amsacrine/High dose Cytarabine. These regimens could achieve complete remission (CR) in a part of patients, but resulted in higher treatment related mortality (TRM). Accordingly, less intensive salvage regimen is needed for elderly patients with relapsed or refractory AML. The activity of histone deacetylase (HDAC) inhibitor, Vorinostat or Suberoylanilide hydroxamic acid (SAHA), against AML has been suggested in cell line models and in animal model as well as in a phase 1 trial. The phase 1 study determined the MTD of oral Vorinostat as 200mg twice daily or 250mg thrice daily. In addition, the phase 1 trial showed the antitumor activity of Vorinostat with 17% of response rate in patients with advanced leukemia or myelodysplastic syndrome (MDS). Accordingly, further study is recommended to demonstrate the clinical activity of Vorinostat in AML. In terms of the combining drug with Vorinostat, anthracycline is one of the best candidate. A in vitro study demonstrated that the combination of anthracycline (esp. idarubicin) with HDAC inhibitor have significant clinical activity against leukemia. Another candidate is Gemtuzumab ozogamicin, which is a calicheamicin-conjugated antibody directed against CD33 antigen on AML blasts. The U.S. FDA also approved the use of GO in relapsed AML as a monotherapy. A study also showed that the combinational therapy of GO with attenuated doses of standard induction chemotherapy could successfully induce CR without increasing treatment-related mortality in AML patients aged 55 or older. A in vitro study reported that HDAC inhibitor valproic acid augmented the clinical activity of GO toward CD33+ AML cells. The study demonstrated that the strategy using HDAC inhibitor together with GO could potentially induce synergistic proapoptotic activity against AML blasts without increasing toxicity. In our center, so far we treated relapsed or refractory AML patients using the salvage regimen including GO (3mg/m2/dayx1day) plus attenuated Idarubicin/Cytarabine (Idarubicin 12mg/m2/day for 2 days and intermediate dose Cytarabine). So far, the CR rate from the regimen is around 50% without increasing TRM. Accordingly, we will determine the efficacy and toxicity of Vorinostat-incorporating salvage regimen based on the GO+IA chemotherapy in patients 50 years old or older with relapsed or refractory AML.
This research is being done to see if the combination of sargramostim and MS-275 will help to improve the bone marrow function of people with myelodysplastic syndrome (MDS) or acute myeloid leukemia(AML). It will also determine the side effects of this combination.
