Abstract Background - Acute myeloid leukemia (AML) in elderly patients (>65 years) is associated with poor prognosis with median overall survival (mOS) of 6 months. Hypomethylating agents (Azacytidine (Aza) and Decitabine) are used in elderly patients who are not candidates for intensive chemotherapy. Aza has resulted in complete remission/complete remission with incomplete hematologic recovery (CR/CRi) of 18-27.8% and mOS of 10.4-24.5 months. Decitabine resulted in CR/CRi of 18-47% and mOS of 7.7-8 months. We conducted a systemic review to assess survival benefit of novel combination drug regimens (CDR) involving hypomethylating agent (HMA) in elderly patients with newly diagnosed AML. Methods - Comprehensive literature search was conducted in Medline, Embase and Cochrane database. We included phase I/II studies only that used CDR involving HMA. Results - Initial database search (since inception) lead to 975 studies. After exclusion (duplicates, case reports, relapsed/refractory AML) final analysis included 17 studies(n=540) Ten phase I/II CDR studies involving Aza (n=334) were included. The various drugs used in combination included valproic acid/all trans retinoic acid (n= 42 ,CR/CRi=26.2% mOS= 18.1 m), thalidomide (n= 14,CR/CRi= 29%, mOS= 13.2 m ), gemtuzumab ozogamicin (GO) (n= 142,CR/CRi = 35-44%, mOS= 11 m), lenalidomide (n= 45,CR/CRi=28-44% , mOS= 3-8.2 m), panobinostat (n=38,CR/CRi=10-22.4%, mOS= 8 m), midostaurin (n=12,CR/CRi=25%, mOS=6 m) , entinostat (n=18 ,CR/CRi=0% ,mOS= 6 m ), Seven phase I/II CDR studies(n=206) involving decitabine were included. Drugs used in combination included low dose cytarabine and aclarubicin (n= 85 ,CR/CRi = 64.7% , mOS= 10-12 m ), tosedostat (n=17 ,CR/CRi= 59% mOS= 11.5 m ), bexarotene(n= 4 ,CR/CRi= 0% mOS= 9.2 m), valproic acid(n= 62 ,CR/CRi= 9% mOS= 7.4m) , GO (n= 40,CR/CRi= 45% , mOS= 7m ),bortezomib (n= 10,CR/CRi= 50% ), vorinostat(n = 31,CR/CRi= 30%). Seven studies reported outcomes for patients with adverse cytogenetics separately. Of these, Aza with lenalidomide (n= 11) had a mOS of 9.5 months and with panobinostat (n=12) the overall response rate was 25% and mOS of 7 months. Similarly, decitabine with vorinostat (n = 8) and tosedostat(n =12) resulted in CR/CRi of 25% and 43% respectively. Long term outcomes for these CDR with decitabine were not reported. In two additional studies, valproic acid/all trans retinoic acid given with AZA and low dose cytarabine & aclarubicin with decitabine(p=0.023) showed poor outcome through multivariable cox model analysis. Five studies reported response rates for subgroup of patients with secondary AML using HMA. Of these, Aza with lenalidomide (n= 16) had a CR/CRi = 27% with median response duration of 21.3 weeks, a CR/CRi of 0% with entinostat (n= 18) and CR/CRi of 22% with thalidomide(n=9). Decitabine given with tosadostat (n= 10) had CR/CRi of 60% and with bortezomib(n=3) the CR/CRi was 66%. The long term outcomes were not reported for these patients. Conclusion - Novel combinations involving Aza with valproic acid/all trans retinoic acid, thalidomide, or GO showed similar CR/CRi and mOS compared to Aza alone. Tosedostat, low dose cytarabine, and aclarubicin given in combination with decitabine showed best results with superior CR/CRi and mOS compared to decitabine alone. Bexarotene with decitabine also improved mOS over decitabine alone despite lower CR/CRi. In patients with adverse cytogenetics, Aza with lenalidomide or panobinostat showed superior CR/CRi and mOS. Decitabine given with vorinostat and tosedostat also showed superior CR/CRi. In patients with secondary AML, Aza in combination with lenalidomide or thalidomide and decitabine with tosedostat or bortezomib showed superior CR/CRi. These CDR for patients with adverse cytogenetics and secondary AML need further testing in studies designed with this specific patient population in which long term outcomes are also measured. These CDR need to be evaluated in large, randomized, prospective studies to assess definitive benefit. Disclosures No relevant conflicts of interest to declare.

Abstract Abstract 1480 Acute promyelocytic leukemia (APL) is a distinct subtype of acute myelogenous leukemia (AML), which usually presents with pancytopenia, coagulopathies and bleeding. Molecular studies have revealed that it was caused by leukemogenic PML-RARA fusion gene resulting from a specific chromosomal translocation t(15;17). The administration of target agent all-trans-retinoic acid (ATRA) combined with anthracycline-based chemotherapy for induction and consolidation followed by ATRA plus low-dose chemotherapy maintenance is the standard strategies for patients with newly diagnosed APL. However, despite the high cure rate, early death and leukemia relapse are the two main important obstacles. We evaluated the efficacy of low-dose All-trans-retinoic acid (ATRA) plus individually adapted chemotherapy for induction followed by arsenic trioxide (ATO) based post-remission therapy in newly diagnosed acute promyelocytic leukemia (APL). From January 2004 to September 2011, 109 patients with APL were enrolled the study. The complete remission (CR) rate was 96.3%. The early death rate was 0.9%. Two arms were assigned according to post-remission protocols: ATO group cases were treated with standard chemotherapy, ATO, and ATRA. Without ATO group cases were subsequently treated with chemotherapy and ATRA only. Patients were monitored by reverse transcriptase-polymerase chain reaction (RT-PCR) during and after treatment. The six-year relapse-free survival (RFS) was significantly better for patients in ATO group than in without ATO group, 94.4% versus 50.6% (P < 0.0001) and the six-year overall survival (OS) rate was 95.7% versus 64.1%, in two groups (P = 0.003). This study shows that low-dose ATRA plus tailored chemotherapy is effective in induction therapy, and the addition of ATO to post-remission therapy significantly improves the long-term outcome.

All-trans retinoic acid (ATRA) and valproic acid (VP) have been tried in the treatment of non-promyelocytic variants of acute myeloid leukemia (AML). Non-randomized studies suggest that the two drugs can stabilize AML and improve normal peripheral blood cell counts. In this context, we used a proteomic/phosphoproteomic strategy to investigate the in vivo effects of ATRA/VP on human AML cells. Before starting the combined treatment, AML responders showed increased levels of several proteins, especially those involved in neutrophil degranulation/differentiation, M phase regulation and the interconversion of nucleotide di- and triphosphates (i.e., DNA synthesis and binding). Several among the differentially regulated phosphorylation sites reflected differences in the regulation of RNA metabolism and apoptotic events at the same time point. These effects were mainly caused by increased cyclin dependent kinase 1 and 2 (CDK1/2), LIM domain kinase 1 and 2 (LIMK1/2), mitogen-activated protein kinase 7 (MAPK7) and protein kinase C delta (PRKCD) activity in responder cells. An extensive effect of in vivo treatment with ATRA/VP was the altered level and phosphorylation of proteins involved in the regulation of transcription/translation/RNA metabolism, especially in non-responders, but the regulation of cell metabolism, immune system and cytoskeletal functions were also affected. Our analysis of serial samples during the first week of treatment suggest that proteomic and phosphoproteomic profiling can be used for the early identification of responders to ATRA/VP-based treatment.

Even though allogeneic stem cell transplantation is the most intensive treatment for acute myeloid leukemia (AML), chemo-resistant leukemia relapse is still one of the most common causes of death for these patients, as is transplant-related mortality, i.e., graft versus host disease, infections, and organ damage. These relapse patients are not always candidates for additional intensive therapy or re-transplantation, and many of them have decreased quality of life and shortened expected survival. The efficiency of azacitidine for treatment of posttransplant AML relapse has been documented in several clinical trials. Valproic acid is an antiepileptic fatty acid that exerts antileukemic activity through histone deacetylase inhibition. The combination of valproic acid and all-trans retinoic acid (ATRA) is well tolerated even by unfit or elderly AML patients, and low-toxicity chemotherapy (e.g., azacitidine) can be added to this combination. The triple combination of azacitidine, valproic acid, and ATRA may therefore represent a low-intensity and low-toxicity alternative for these patients. In the present review, we review and discuss the general experience with valproic acid/ATRA in AML therapy and we discuss its possible use in low-intensity/toxicity treatment of post-allotransplant AML relapse. Our discussion is further illustrated by four case reports where combined treatments with sequential azacitidine/hydroxyurea, valproic acid, and ATRA were used.
