Azacitidine is the first agent to significantly prolong overall survival (OS) compared with conventional care regimens in patients with higher-risk myelodysplastic syndromes (MDS). Here, we review currently available data on azacitidine treatment in lower-risk MDS. In a phase III study, a subset of patients with lower-risk MDS treated with azacitidine achieved an overall response rate (ORR) of 60% and a longer median OS compared with supportive care (44 vs 27 months). In a phase II study investigating various azacitidine dose schedules, the

The proportion of attributable deaths varied according to a patients MDS risk status. The proportion of deaths attributable to MDS increased from 31.5% among low-risk patients to 48.8% in the intermediate-risk category and 74.1% of patients with high-risk MDS. CAD/stroke as the cause of death decreased from a high of 26.3% of patients with low-risk disease to 20.6% of patients with intermediate risk-MDS to 9.3% of patients with high-risk MDS.. Treatment of Myelodysplastic Syndrome. Lower-risk myelodysplastic syndrome patients are treated initially for the specific complications of the disease, such as anemia and low blood counts. If more aggressive therapy is needed, strategies that are considered standard of care include chemotherapy using hypomethylating agents (5-azacitidine and decitabine) and lenalidomide.. Higher-risk myelodysplastic syndrome patients usually need more aggressive therapy, but much depends on the age and condition of the patient. Younger patients with high-risk disease are ...

OUTLINE: This is a dose deescalation study of azacitidine.. Patients receive azacitidine subcutaneously daily on days 1-5 and 29-33 followed by phenylbutyrate IV continuously on days 5-12 and 33-40. Treatment continues for at least 2 courses in the absence of disease progression. Patients with responsive disease may receive an additional 2 months of therapy.. Cohorts of 3-6 patients receive deescalating doses of azacitidine until the minimal effective pharmacologic dose (MEPD) is determined. The MEPD is defined as the dose above the dose at which more than 1 of 6 patients do not meet the target enzyme inhibition of greater than 90%.. Once the MEPD and toxicity have been established for a 5 day schedule, daily dose schedule of azacitidine is increased to 10, 14, and 21 days, followed by phenylbutyrate for 7 days. Courses are repeated every 28 days.. PROJECTED ACCRUAL: Approximately 32 patients will be accrued for this study within 2 years. ...

Compared with World Health Organization-defined acute myeloid leukaemia (AML) not otherwise specified, patients with AML with myelodysplasia-related changes (AML-MRC) are generally older and more likely to have poor-risk cytogenetics, leading to poor response and prognosis. More than one-half of all older (≥65 years) patients in the phase 3 AZA-AML-001 trial had newly diagnosed AML-MRC. We compared clinical outcomes for patients with AML-MRC treated with azacitidine or conventional care regimens (CCR; induction chemotherapy, low-dose cytarabine, or supportive care only) overall and within patient subgroups defined by cytogenetic risk (intermediate or poor) and age (65-74 years or ≥75 years). The same analyses were used to compare azacitidine with low-dose cytarabine in patients who had been preselected to low-dose cytarabine before they were randomized to receive azacitidine or CCR (ie, low-dose cytarabine). Median overall survival was significantly prolonged with azacitidine (n = 129) versus CCR (n

Myelodysplastic syndromes (MDS) are a heterogeneous group of clonal hematopoietic stem cell disorders that have a substantial impact on patients quality of life, in addition to causing significant morbidity and mortality. The hypomethylating agents (HMAs) azacitidine and decitabine are approved for use in the United States and in Europe for the treatment of MDS or acute myeloid leukemia (AML) and, in the case of azacitidine, prolong survival in higher-risk patients.

The spin-trap free radical scavenger N-tert-butyl-a-phenylnitron (PBN) ameliorated effects of several teratogens involving reactive oxygen species (ROS). We investigated for the first time whether PBN could ameliorate teratogenesis induced by a DNA hypomethylating hematological therapeutic 5-azacytidine (5azaC). At days 12 and 13 of gestation, Fisher rat dams were pretreated by an i.v. injection of PBN (40mg/kg) and 1 h later by an i.p. injection of 5azaC (5mg/kg). Development was analyzed at gestation day 15 in embryos and day 20 in fetuses. PBN alone did not significantly affect development. PBN pretreatment restored survival of 5azaC-treated dams embryos to the control level, restored weight of embryos and partially of fetuses, and partially restored crownrump lengths. PBN pretreatment converted limb adactyly to less severe oligodactyly. PBN pretreatment restored global DNA methylation level in the limb buds to the control level. Cell proliferation in limb buds of all 5azaCtreated dams ...

Azacytidine is an inhibitor of DNA methyltransferase and is known to be an anti-leukemic agent to induce cancer cell apoptosis. In the present study, multiple myeloma cells were treated with azacytidine at clinically relevant concentrations to induce necrosis through oxidative stress. Necrotic myeloma cells exhibit unique characteristics, including enrichment of the cell-bound albumin and overexpression of endoplasmic reticulum (ER)- and mitochondrial-specific chaperones, which were not observed in other necrotic cells, including HUH-7, A2780, A549, and Hoc1a. Proteomic analysis shows that HSP60 is the most abundant up-regulated mitochondrial specific chaperone, and azacytidine-induced overexpression of HSP60 is confirmed by western blot analysis. In contrast, expression levels of cytosolic chaperones such as HSP90 and HSP71 were down-regulated in azacytidine-treated myeloma cells, concomitant with an increase of these chaperones in the cell culture medium, suggesting that mitochondrial chaperones and

The role of neurotrophic factors (NTFs) in neuronal development, differentiation, neuroprotection, and maintenance is well documented. The novel family of mesencephalic astrocyte-derived neurotrophic factor (MANF) and cerebral dopamine neurotrophic factor (CDNF) have been found to protect dopaminergic neurons, providing a potential therapeutic avenue for neurodegenerative diseases. Our group has previously shown an induction of NTFs including MANF and CDNF, following treatment with valproic acid (VPA), a histone deacetylase (HDAC) inhibitor, in both cultured cells and rat brain. Furthermore, increased histone H3 acetylation was observed, indicating that epigenetic mechanisms may play a role in the modulation of MANF and CDNF. The interaction between HDAC inhibitors and DNA demethylation prompted us to investigate if DNA demethylation plays a role in the regulation of these NTFs. Treatment with 5-azacytidine (AZA; 1 - 25 µM), a potent DNA demethylating agent, for 24 hours, resulted in a ...

Aberrant DNA methylation is a common feature of cancer, which has been targeted for pharmacologic intervention because of its reversible nature. Nucleoside analogs such as 5-azacytidine, 5-aza-2-deoxycytidine, and zebularine are mechanism-based inhibitors of DNA methylation that are incorporated into the DNA during replication and deplete the DNA methyltransferase enzymes. 5-Azacytidine and 5-aza-2-deoxycytidine are extremely potent inhibitors and may be ideal for use in chemotherapy of cancer. Delivery of these inhibitors has been facilitated with the use of short oligonucleotides that prevent enzymatic degradation. On the other hand, zebularine, a more stable and less toxic surrogate of the other two compounds may be best utilized as a chemopreventive agent. Chronic oral administration of zebularine in a murine colon cancer model highlighted its low toxicity and gender- and tissue-specific action against DNA methylation ...

GPR109A is the receptor for short-chain fatty acids. The functions of GPR109A have been the subject of extensive studies; however, the molecular mechanisms underlying GPR109A expression is largely unknown. We show that GPR109A is highly expressed in normal human colon tissues, but is silenced in human colon carcinoma cells. ...

During the past decade, intense effort has been focused on the development of specific FXS treatments that might lead to eventual cure. Two possible approaches are presently being considered for a substantial treatment of FXS: (a) reactivation of the affected gene and (b) compensating for the lack of FMRP.. Epigenetic modulators. The strategy of restoring FMR1 gene activity, which is based on the presence of the intact FMR1 coding sequence, targets potentially reversible epigenetic changes, primarily DNA methylation. The first compound tested on cells derived from patients with FXS was the drug 5-aza-deoxycytidine (5-azadC, a methyltransferase inhibitor; Figure 3A), which restored transcription and translation of the FMR1 gene (95). Furthermore, treatment with histone deacetylase inhibitors (TSA, butyrate, and 4-phenylbutyrate) potentiated the effect of 5-azadC (96). Reactivation was accompanied not only by DNA demethylation but also by changes in the epigenetic code of histones H3 and H4 (97). ...

Bae et al. [6] suggest that three dimensional (3D) culture system could promote the osteogenic and adipogenic differentiation potential of bone-marrow derived mouse MSCs, and additional treatment of azacitidine (AZA), a DNA methyltransferase inhibitor, could further enhance the osteogenic differentiation ability. However, other progenitor properties, including proliferation and colony-forming efficiency were not significantly affected by either treatment compared to conventionally cultured MSCs.. Bone-marrow derived MSCs reside within a complex environment in which MSCs are subjected to various mechanical stimuli of the bone and also environmental stimuli from interacting cell types. However, classic two dimensional (2D) cultures lack these mechanical stimuli and vital cues by hematopoietic cells and nonadherent population of mesenchymal progenitors. Therefore, to preserve MSC progenitor potency, studies have focused on expansion techniques to recreate an elaborate bone marrow niche through 3D ...

IWG) criteria. With a median duration of follow-up of 10.8 months, the median duration of response was 8.4 months and the median duration of CR was 7.3 months. Seventeen (52%) evaluable MDS patients discontinued therapy to pursue stem cell transplant. Median overall survival (OS) for all enrolled patients (n=55) was 10.8 months. Median OS in responding patients versus non-responders was 13.7 vs. 3.9 months. Adverse events, regardless of causality, were mostly grade 1/2. Grade 3+ adverse events occurring in ≥20% of patients were limited to cytopenias and infection, consistent with underlying hematopoietic malignancies, and no exacerbation of the expected AZA-related safety profile has been observed..

Promoter hypermethylation of genes important in the regulation of cell proliferation and differentiation is a frequent abnormality observed in primary neoplasms and tumor cell lines (40 , 41) . Thus, the application of pharmacologic inhibitors of DNA methylation provides an attractive and rational approach to re-establish the antiproliferative and differentiation-inducing signals silenced by hypermethylation (42) . However, the preliminary results of studies with methylation inhibitors in the clinical trials were not encouraging. Initial trials of 5-azacytidine in patients with sickle cell disease and β-thalassemia (43 , 44) were abandoned because of an apparent increase in the incidence of tumors in rats treated with this agent (45) . In 1988, a novel methylation inhibitor DAC was reported to be nontumorigenic and was shown to demonstrate antitumor effects in animal models (46) . Moreover, studies of methylation inhibitors in patients with myelodysplastic syndrome and acute myeloid leukemia ...

The integrin α6β4 is upregulated in pancreatic carcinoma and signaling from this integrin promotes metastatic properties, including cancer cell invasion. We have previously shown that the integrin α6β4 promotes such properties by dramatically altering the transcriptome toward an invasive phenotype. Furthermore, we have found that transcriptome alterations can be accomplished through targeted DNA demethylation of specific promoters, as we have shown with the pro-metastatic gene S100A4. In this study, we find that signaling from the integrin α6β4 dramatically upregulates expression of amphiregulin (Areg) and epiregulin (Ereg), ligands for the epidermal growth factor receptor (EGFR), and that these ligands promote pancreatic carcinoma invasion. To determine if Areg and Ereg are regulated by DNA methylation, pancreatic cancer cells with low expression of the integrin α6β4 were treated with the DNA methyltransferase inhibitor 5-aza-2-deoxycytidine (DAC), which resulted in stable over ...

By 2018, five new drugs will have been launched for the treatment of myelodysplastic syndromes (MDS), three of which are expected to offer much-needed second-line therapeutic options in the hypomethylating agent (HMA)-refractory higher-risk MDS population, according to a new study. - News - PharmaTimes

Myelodysplastic syndromes (MDS) are a heterogeneous group of clonal hematopoietic neoplasms, manifesting with dysplastic bone marrow failure, peripheral blood cytopenias and variable predisposition for transformation to acute myeloid leukemia (AML). Diagnosis is heavily reliant on non-specific, subjective morphology, particularly in early stages - karyotype results are most often normal, and no MDS-specific molecular assays currently exist. Diagnosis is often delayed, requiring serial invasive bone marrow investigations. Moreover, MDS primarily afflicts older adults and, without molecular targets and assays, treatments are mainly supportive (i.e. blood transfusions and growth factors). While some MDS patients respond to emerging agents, such as hypomethylating agents, it is not entirely clear how to predict treatment responses. With our aging demographics, MDS prevalence is expected to increase, along with demands for novel and more personalized treatment. Recurring MDS-associated somatic ...

TAMPA, Fla. - Researchers at Moffitt Cancer Center have completed a phase II clinical trial to determine the safety and efficacy of dasatinib for patients with higher-risk myelodysplastic syndromes (MDS), chronic myelomonocytic leukemia, or acute myeloid leukemia resulting from MDS and have failed treatment with azanucleosides. The therapy may not be effective for all patients, but those with trisomy 8 chromosomal disorder have higher rates of stable disease and respond better to treatment with dasatinib, the study shows.. Results of this study appear in the March issue of Leukemia Research.. Myelodysplastic syndromes are disorders of the stem cell in bone marrow. The marrow does not produce enough normal blood cells for the body. As the number of quality blood-forming cells declines, blood production is impaired.. According to the researchers, stem cell transplantation is the only potentially curative option for MDS but also has risks of morbidity and mortality. A class of medication called ...

The bone marrow microenvironment influences malignant hematopoiesis, but how it promotes leukemogenesis has not been elucidated. In addition, the role of the bone marrow stroma in regulating clinical responses to DNA methyltransferase inhibitors (DNMTi) is also poorly understood. In this study, we conducted a DNA methylome analysis of bone marrow-derived stromal cells from myelodysplastic syndrome (MDS) patients and observed widespread aberrant cytosine hypermethylation occurring preferentially outside CpG islands. Stroma derived from 5-azacytidine-treated patients lacked aberrant methylation and DNMTi treatment of primary MDS stroma enhanced its ability to support erythroid differentiation. An integrative expression analysis revealed that the WNT pathway antagonist FRZB was aberrantly hypermethylated and underexpressed in MDS stroma. This result was confirmed in an independent set of sorted, primary MDS-derived mesenchymal cells. We documented a WNT/β-catenin activation signature in CD34+ cells from

Decitabine is a deoxycytidine analog that is incorporated into DNA, inhibiting DNA methyltransferase (DNMT1/3A/3B) activity. This demethylating agent is clinically used to treat myelodysplastic syndromes. Decitabines inhibition of DNA methyltransferase may be modulated by PKC. Decitabine exhibits anticancer chemotherapeutic, immunomodulatory, and neurotoxic activities. In cellular models of acute myelogenous leukemia (ALL), decitabine demethylation prevents cancer cell inactivation of TRAIL signaling, increasing apoptosis and cell death. In vivo, decitabine stimulates increases in cancer testis antigen-specific cytotoxic (CD8+) T cell activity. In dopaminergic neurons, this compound induces apoptosis and upregulation of tyrosine hydroxylase and α-synuclein, suggesting complications for use in subjects with Parkinsons disease. Decitabine also inhibits replication of HIV in cellular models without displaying cytotoxicity. Additionally, this compound shows benefit in the treatment of sickle-cell ...

The cytocidal activity of arabinosyl-5-azacytosine (araAC) and its effect on the synthesis and methylation of DNA in the human colon carcinoma cell line HT-29 was examined and compared with three other cytidine analogues. Treatment for 2 hr with 10(-6)M arabinosylcytosine (araC), araAC, 5-azacytidine (AZC), or 2-deoxy-5-azacytidine (dAZC) produced a 7-30% reduction in cell viability. Prolongation of drug exposure to 24 hr significantly enhanced the cytotoxicity of all analogues, and particularly dAZC. AZC and dAZC were potent inhibitors of DNA methylation in the absence of inhibition of DNA synthesis, whereas araC and araAC primarily affected DNA synthesis. RNA synthesis was not affected by any of the analogues. dAZC and AZC were incorporated into DNA to a greater extent than were araC or araAC upon short- and long-term drug exposure, whereas only AZC was incorporated into RNA. These data indicate that araAC appears to behave more as an analogue of araC rather than of dAZC or AZC, wherein it ...

This is superb news for cancer patients with rarer cancers. We are extremely pleased with NICEs decision especially as people with myelodyplastic syndrome, chronic myelomonocytic leukaemia, and acute myeloid leukaemia have often been faced with limited treatment options.. When the Governments £200 million fund comes into effect this April it is estimated that an extra 8,000 cancer patients a year could receive cancer treatments, which could improve quality and length of life. But more cancer patients must get the clinically effective drugs their doctors recommend, regardless of their type of cancer or where they live. Tragically and frustratingly this isnt always happening at present.. To ensure all cancer patients get better access to treatments, we want the £200 million Cancer Drugs Fund to prioritise drugs for rarer cancers. It is also important that cancer patients are supported to make informed decisions about their drug treatment options and that funding decisions are well monitored ...

Our present results establish for the first time that MTI-induced apoptosis and 15-LOX-1 expression are linked mechanistically in colorectal cancer cells. The demethylating agents 5-Azadc, 5-azacytidine, and zebularine can induce 15-LOX-1 expression, indicating that methylation may play a role in 15-LOX-1 regulation. 5-Azadc induced 15-LOX-1 expression in a dose- and time-dependent manner and induced growth arrest and apoptosis in Caco-2 colon cancer cells. Inhibiting 15-LOX-1 with caffeic acid (at the 2.2 μmol/L concentration shown to be specific for 15-LOX-1 inhibition) or siRNA attenuated 5-Azadc-induced growth inhibition and apoptosis, indicating a direct relationship between 15-LOX-1 and these biological effects. These findings identify a molecular mechanism by which MTIs induce apoptosis and other cellular effects and further elucidate the role of 15-LOX-1 in human colorectal carcinogenesis. Our findings are consistent with results of other studies, which showed a 15-LOX-1-apoptosis link ...

Through his focus on research-driven patient care, Dr. Kantarjian has helped vastly improve survival and quality of life for leukemia patients everywhere. This award is recognition of his deep impact in the field, Thomas Buchholz, MD, MD Anderson Executive Vice President and Physician-in-Chief, said in a news release.. Kantarjians work has focused on developing several therapies including: clofarabine for acute lymphocytic leukemia (ALL), the hypomethylating agent decitabine for myelodysplastic syndromes, liposomal vincristine for ALL, and ruxolitinib for myelofibrosis. He has also helped develop several targeted therapies for chronic myeloid leukemia (CML) including imatinib, dasatinib, nilotinib, ponatinib, bosutinib, and omacetaxine. He is currently developing monoclonal antibodies in adult ALL.. Kantarjian has been at MD Anderson since 1983, and also holds the Kelcie Margaret Kana Research Chair and serves as Associate Vice President of MD Andersons Global Academic Programs. He was also ...

Notably, hypermethylation of the CDKN2A promoter region has been shown to lead to loss of p16 expression in 19% of primary and 33% metastatic melanomas.[59] DNA methyltransferase(DNMT) inhibitors namely 5-azacytidine, 5-aza-20-deoxycytidine(decitabine), fazarabine, and dihydro-5-azacytidine have been extensively studied ...

Here, we establish that the degree and long-term stability of tumor suppressor gene reactivation induced by 5-azaCdR are locus specific and correlate with the ability to attain and maintain Pol II promoter occupancy. Detailed analysis of the TMS1/ASC locus showed that transient exposure to 5-azaCdR induces DNA demethylation, depletion of H3K9me2, and the reacquisition of H3ac and H3K4me2. This allows for the reengagement of Pol II on the TMS1 promoter and gene reactivation. Using a single-molecule approach, we show that these acquired active marks (H3ac, H3K4me2, and Pol II) preferentially associate with demethylated alleles, whereas H3K9me2 was selectively enriched on those alleles that remain methylated. H4K20me3, a mark typically associated with heterochromatin, was unaffected by 5-azaCdR treatment and was retained on both unmethylated and methylated alleles. After 3 months in the absence of drug, a subpopulation of unmethylated alleles persists and remains associated with the active marks ...

Roche medicines passed important regulatory milestones in recent months, including the following key achievements: In December 2018, the US Food and Drug Administration (FDA) approved Tecentriq in combination with Avastin, paclitaxel and carboplatin for the initial treatment of people with metastatic non-squamous non-small cell lung cancer (NSCLC) with no EGFR or ALK genomic tumour aberrations.. The FDA granted accelerated approval to Venclexta in combination with azacitidine or decitabine, or low dose cytarabine, for the treatment of people with newly-diagnosed acute myeloid leukaemia (AML), aged 75 years and older, or for those ineligible for intensive induction chemotherapy due to coexisting medical conditions.4 AML is the most common type of aggressive leukaemia in adults and has the lowest survival rate of all types of leukaemia.. In October, FDA approved Xofluza (baloxavir marboxil) for the treatment of acute, uncomplicated influenza in people aged 12 years and older. Xofluza is a ...

Right. So lets move on. Actually, were going to talk about that shortly. But I also wanted to bring up some of the results that were presented at SOHO in Houston, or at least virtually this year. I think that Stephane you were there. Courtney presented some data, not on AML, but on MDS. So let me go back to Dan and get his thoughts regarding his general approach and if there is any variance in how he approaches the treatment of IDH mutated MDS. Courtney presented some data that, in combination with azacitidine, IDH inhibition leads to a fairly impressive overall response rate, but the range of responses are different than what you generally see with AML. Much more marrow CRs is much less full CRs, although the benchmark, as we all know, of CR for MDS is a bit higher. But nevertheless, promising data. So what is your general approach to an MDS patient who has an IDH mutation? What type of MDS patient do you sort of generally choose to use IDH inhibitors either in combination or as ...

Treatment of CFS patient PBMCs with 5-azacytidine was omitted from Lombardi et al. paper In September 2011, Abbie Smith, a graduate student and virology blogger, (http://scienceblogs.com/erv/) revealed that Dr. Judy Mikovits, the corresponding author of the Lombardi et al. study, presented a figure at a meeting that turned out to be identical to one in the original paper, but with different patient numbers and experimental conditions (John Cohen, ScienceInsider, http://news.sciencemag.org/scienceinsider/2011/10/xmrv-researcher-fired.html). This revelation led the authors to concede that the patient-derived PBMCs in Lombardi et al. had been treated with 5-azacytidine, an agent used to demethylate DNA and induce transcription from latent genes and proviruses, but did not include this treatment in the paper because it was not germane. The omission of such critical information from the paper cast further doubt on the validity of the entire study. ...
