Filter by:1. Detect the expression of marker CD56 and CD11b in newly diagnosed cases of adult AML. 2. Study correlation between CD56 and CD11b expression with haematological parameters in cases of adult AML.
This is a multi-center, randomized, trial to evaluate the efficacy of adding crenolanib to salvage chemotherapy versus salvage chemotherapy alone in subjects with relapsed/refractory FLT3-mutant AML. Approximately 320 subjects will be randomized 1:1 to receive either salvage chemotherapy (HAM or FLAG-Ida) with crenolanib (treatment arm 1) or salvage chemotherapy (HAM or FLAG-Ida) alone (treatment arm 2).
One-third to one-half of patients with AML relapse and in general relapsed AML patients have a poor prognosis. The treatment of relapsed AML consists of induction chemotherapy followed by Allogenic Stem Cell Transplant (ASCT). However, at present there is no standard salvage chemotherapy regimen for relapsed AML, as no study has shown any one regimen to be significantly superior. Anthracyclines, Fludarabine, Etoposide and cytarabineare active agents in AMLand have been used as monotherapy and in combination in refractory and relapsed AML patients. According to previous studies the present CR rate of different regimens ranges from 50-70%. A retrospective analysis (unpublished) conducted at IRCH, AIIMS on relapsed AML patients treated with ADE (Cytarabine, Daunorubicin and Etoposide) chemotherapy showed the CR rates of approximately 70%. Therefore, we have planned this study to test the efficacy and toxicity of ADE induction chemotherapy in relapsed AML patients in a prospective manner.
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 study will be an open label, single arm, phase I study intended to identify the safety and tolerability of "AML Cell Vaccine" given to eligible MDS RAEB-2 and AML patients who have achieved a best response of complete remission or partial remission following their first or second course of standard induction chemotherapy.
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).
PET/CT is reliable tool in evaluation of treatment response in number cancers. F18-FLT is a precursor of DNA with high uptake in the bone marrow as a part of normal biodistribution. Highly increased uptake of this radiopharmaceutical was shown in a number of hematologic disease either in bone marrow or extramedullary. F18-FLT PET/CT can provide a tool for whole body assessment of activity in bone marrow as well as early estimation of treatment efficacy or lack of it. In addition, this noninvasive study can replace bone marrow biopsy and predict response vs. non response to therapy.
RATIONALE: Studying samples of bone marrow and blood from patients with cancer who failed treatment may help doctors learn more about changes that occur in DNA and identify biomarkers related to cancer resistance. It may also help doctors find better ways to treat cancer. PURPOSE: This research trial studies biomarkers in samples from adult patients with acute myeloid leukemia who failed standard-of-care treatment.
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.
