Epigenetic therapy is associated with similar survival compared with intensive chemotherapy in older patients with newly diagnosed acute myeloid leukemia.

ABSTRACT: We reviewed the outcome of 671 patients 65 years of age or older with newly diagnosed acute myeloid leukemia (AML) treated at our institution between 2000 and 2010 with intensive chemotherapy (n = 557) or azacitidine- or decitabine-based therapy (n = 114). Both groups were balanced according to cytogenetics and performance status. The complete response rates with chemotherapy and epigenetic therapy were 42% and 28%, respectively (P = .001), and the 8-week mortality 18% and 11%, respectively (P = .075). Two-year relapse-free survival rates (28% vs 39%, P = .843) and median survival (6.7 vs 6.5 months, P = .413) were similar in the 2 groups. Multivariate analysis identified older age, adverse cytogenetics, poor performance status, elevated creatinine, peripheral blood and BM blasts, and hemoglobin, but not type of AML therapy, as independent prognostic factors for survival. No outcome differences were observed according to cytogenetics, FLT3 mutational status, age, or performance status by therapy type. Decitabine was associated with improved median overall survival compared with azacitidine (5.5 vs 8.8 months, respectively, P = .03). Survival after failure of intensive chemotherapy, azacitidine, or decitabine was more favorable in patients who had previously received decitabine (1.1 vs 0.9 vs 3.1 months, respectively, P = .109). The results of the present study show that epigenetic therapy is associated with similar survival rates as intensive chemotherapy in older patients with newly diagnosed AML. The studies reviewed are registered at www.clinicaltrials.gov as 2009-0172 (NCT00926731) and 2009-0217 (NCT00952588).

Project description:Acute myeloid leukemia (AML) is an aggressive hematological malignancy with a globally poor outcome, especially in patients ineligible for intensive chemotherapy. Until recently, therapeutic options for these patients included low-dose cytarabine (LDAC) or the hypomethylating agents (HMA) azacitidine and decitabine, which have historically provided only short-lived and modest benefits. The oral B-cell lymphoma 2 inhibitor, venetoclax, Venetoclax, an oral B-cell lymphoma 2 (BCL2) inhibitor, is now approved by the USA Food and Drug Administration (FDA) in combination with LDAC or HMA in older AML patients ineligible for intensive chemotherapy. Is now approved by the US Food and Drug Administration for this indication. In the pivotal clinical trials evaluating venetoclax either in combination with LDAC or with HMA, the rates of complete remission (CR) plus CR with incomplete hematological recovery were 54% and 67%, respectively and the median overall survival (OS) was 10.4?months and 17.5?months, respectively, comparing favorably with outcomes in clinical trials evaluating single-agent LDAC or HMA. The most common adverse events with venetoclax combinations are gastrointestinal symptoms, which are primarily low grade and easily manageable, and myelosuppression, which may require delays between cycles, granulocyte colony-stimulating factor (G-CSF) administration, or decreased duration of venetoclax administration per cycle. A bone marrow assessment after the first cycle of treatment is critical to determine dosing and timing of subsequent cycles, as most patients will achieve their best response after one cycle. Appropriate prophylactic measures can reduce the risk of venetoclax-induced tumor lysis syndrome. In this review, we present clinical data from the pivotal trials evaluating venetoclax-based combinations in older patients ineligible for intensive chemotherapy, and provide practical recommendations for the prevention and management of adverse events associated with venetoclax.
