Novel therapies upon failure of HMA plus venetoclax.

The efficacy and tolerability of the combination of hypomethylating agents with venetoclax (HMA-VEN) in patients with newly diagnosed acute myeloid leukemia has been a practice-changing milestone in the field. However, treatment failure and relapse remain major barriers to prolonged survival. TP53 mutation is a predictor of primary induction failure and portends especially poor outcomes.

Phase 1 study of selinexor in combination with salvage chemotherapy in Adults with relapsed or refractory Acute myeloid leukemia.

Selinexor, an oral inhibitor of the nuclear transport protein Exportin-1, shows promising single-agent activity in clinical trials of relapsed/refractory (R/R) acute myeloid leukemia (AML) and preclinical synergy with topoisomerase (topo) IIα inhibitors. We conducted a phase 1, dose-escalation study of selinexor with mitoxantrone, etoposide, and cytarabine (MEC) in 23 patients aged < 60 years with R/R AML. Due to dose-limiting hyponatremia in 2 patients on dose level 2 (selinexor 40 mg/m), the maximum tolerated dose was 30 mg/m.

Hematopoietic Cell Transplantation in the Management of Myelodysplastic Syndrome: An Evidence-Based Review from the American Society for Transplantation and Cellular Therapy Committee on Practice Guidelines.

The sole curative therapy for myelodysplastic syndrome (MDS) is allogeneic hematopoietic cell transplantation (HCT). Here this therapeutic modality is reviewed and critically evaluated in the context of the evidence. Specific criteria were used for searching the published literature and for grading the quality and strength of the evidence and the strength of the recommendations.

Psychological Distress in Young Adults with Acute Myeloid Leukemia Undergoing Induction Chemotherapy.

Young adults (YAs), aged 18-39 years, with acute myeloid leukemia (AML) navigate life disruptions amid an unpredictable illness trajectory. We conducted a secondary analysis of patient-reported outcomes for hospitalized YAs with high-risk AML receiving intensive chemotherapy, collected during a multisite randomized clinical trial. Of the 160 patients, 14 (8.

Phase 3 randomized trial of chemotherapy with or without oblimersen in older AML patients: CALGB 10201 (Alliance).

Overexpression of B-cell leukemia/lymphoma 2 (BCL2) renders acute myeloid leukemia (AML) cells resistant to chemotherapy and has been associated with unfavorable outcomes. Oblimersen (G3139) is a phosphorothioate 18-mer antisense oligonucleotide directed against the first 6 BCL2 codons. In a phase 1 study of AML patients treated with G3139, cytarabine, and daunorubicin induction with cytarabine consolidation, no antisense-related toxicity was reported, and BCL2 downregulation occurred in patients achieving complete remission.

Effectiveness of Integrated Palliative and Oncology Care for Patients With Acute Myeloid Leukemia: A Randomized Clinical Trial.

Importance: Patients with acute myeloid leukemia (AML) receiving intensive chemotherapy experience substantial decline in their quality of life (QOL) and mood during their hospitalization for induction chemotherapy and often receive aggressive care at the end of life (EOL). However, the role of specialty palliative care for improving the QOL and care for this population is currently unknown.

Objective: To assess the effect of integrated palliative and oncology care (IPC) on patient-reported and EOL outcomes in patients with AML.

How to approach shared decision making when determining consolidation, maintenance therapy, and transplantation in acute myeloid leukemia.

Until recently, treatment options for patients with acute myeloid leukemia (AML) were limited to cytotoxic chemotherapeutic agents that possessed little specificity for the cytogenetic and molecular mutations known to risk stratify patients with this disease. With the approval of multiple new therapies, not only have the agents that we treat patients with changed, but the way we talk about these options, decide on, and manage therapy has also been transformed. Given these complexities, it is important that we help patients make an informed decision by weighing the risk of relapse with patient wishes and desired quality of life.

Incidence of venous thrombosis after peg-asparaginase in adolescent and young adults with acute lymphoblastic leukemia.

Aim: There are limited data describing incidence of symptomatic venous thromboembolism (VTE) in adolescent and young adult (AYA) acute lymphoblastic leukemia (ALL) patients receiving peg-asparaginase.

Materials & Methods: Single-institution retrospective analysis of 44 AYA ALL patients treated with peg-asparaginase. Rates of VTE and proposed risk factors were assessed.

The Incidence of Invasive Fungal Infections in Patients With AML Treated With a Hypomethylating Agent.

Background: Newly diagnosed patients with acute myeloid leukemia (AML) who receive induction with a hypomethylating agent (HMA) are often neutropenic with an increased risk for invasive fungal infections (IFIs). This study analyzed the incidence and risk factors for IFIs in these patients, evaluated clinical patterns in antifungal prophylaxis, and assessed the diagnostic utility of tests in this setting.

Patients And Methods: We studied 117 newly diagnosed patients with AML treated with HMAs at our center, divided into groups based on concern for IFI (cIFI: all possible, probable, and proven IFIs) versus no concern for IFI.

Entospletinib in Combination with Induction Chemotherapy in Previously Untreated Acute Myeloid Leukemia: Response and Predictive Significance of and Expression.

Purpose: Spleen tyrosine kinase (SYK) signaling is a proposed target in acute myeloid leukemia (AML). Sensitivity to SYK inhibition has been linked to and overexpression in preclinical studies. This trial evaluated the safety and efficacy of entospletinib, a selective inhibitor of SYK, in combination with chemotherapy in untreated AML.

Phase I study of AR-42 and decitabine in acute myeloid leukemia.

This phase I trial sought to determine a biologically safe and effective dose of AR-42, a novel histone deacetylase inhibitor, which would lead to a doubling of miR-29b prior to decitabine administration. Thirteen patients with previously untreated or relapsed/refractory AML were treated at 3 dose levels (DL): AR-42 20 mg qd on d1,3,5 in DL1, 40 mg qd on d1,3,5 in DL2 and 40 mg qd on d1,3,4,5 in DL3. Patients received decitabine 20 mg/m on d6-15 of each induction cycle and 20 mg/m on d6-10 of each maintenance cycle.

Resistance Mechanisms to SYK Inhibition in Acute Myeloid Leukemia.

Spleen tyrosine kinase (SYK) is a nonmutated therapeutic target in acute myeloid leukemia (AML). Attempts to exploit SYK therapeutically in AML have shown promising results in combination with chemotherapy, likely reflecting induced mechanisms of resistance to single-agent treatment . We conducted a genome-scale open reading frame (ORF) resistance screen and identified activation of the RAS-MAPK-ERK pathway as one major mechanism of resistance to SYK inhibitors.

Selinexor in combination with decitabine in patients with acute myeloid leukemia: results from a phase 1 study.

Current treatment options for older and relapsed or refractory (R/R) acute myeloid leukemia (AML) patients are limited and represent an unmet need. Based on preclinical studies showing strong anti-leukemic effects this phase I dose-escalation study assessed the safety and preliminary clinical activity of the oral exportin-1 inhibitor, selinexor, in combination with the hypomethylating agent, decitabine 20 mg/m, in adults with R/R AML and in older (age ≥ 60) untreated AML patients. There were no protocol-defined dose limiting toxicities.

Safety and efficacy of oral panobinostat plus chemotherapy in patients aged 65 years or younger with high-risk acute myeloid leukemia.

The role of histone deacetylase inhibitors in the treatment of acute myeloid leukemia (AML) is not well characterized. The current study evaluated the safety and efficacy of panobinostat in combination with idarubicin and cytarabine in newly diagnosed patients aged ≤65 years with primary or secondary high-risk AML based on cytogenetic classification. Treatment included fixed dose idarubicin (12 mg/m/d, IV; day 1-3) and cytarabine (100 mg/m/d, continuous IV infusion; day 1-7) and escalating oral doses of panobinostat at 15 mg, 20 mg, and 25 mg, thrice weekly starting at week 2 of a 28-day cycle.

Preclinical activity and a pilot phase I study of pacritinib, an oral JAK2/FLT3 inhibitor, and chemotherapy in FLT3-ITD-positive AML.

Activating FLT3 internal tandem duplication (FLT3-ITD) mutations in acute myeloid leukemia (AML) associate with inferior outcomes. We determined that pacritinib, a JAK2/FLT3 inhibitor, has in vitro activity against FLT3-ITD and tyrosine kinase domain (TKD) mutations. Therefore, we conducted a phase I study of pacritinib in combination with chemotherapy in AML patients with FLT3 mutations to determine the pharmacokinetics and preliminary toxicity and clinical activity.

A novel regimen for relapsed/refractory adult acute myeloid leukemia using a partial tandem duplication targeted therapy: results of phase 1 study NCI 8485.

partial tandem duplication occurs in approximately 5-10% of patients with acute myeloid leukemia and is associated with adverse prognosis. wild type is epigenetically silenced in partial tandem duplication; re-expression can be induced with DNA methyltransferase and/or histone deacetylase inhibitors , sensitizing myeloid blasts to chemotherapy. We hypothesized that epigenetic silencing of wildtype contributes to partial tandem duplication-associated leukemogenesis and pharmacologic re-expression activates apoptotic mechanisms important for chemoresponse.

A comparison of toxicities in acute myeloid leukemia patients with and without renal impairment treated with decitabine.

Purpose There are limited data regarding the clinical use of decitabine for the treatment of acute myeloid leukemia in patients with a serum creatinine of 2 mg/dL or greater. Methods We retrospectively evaluated 111 patients with acute myeloid leukemia who had been treated with decitabine and compared the development of toxicities during cycle 1 in those with normal renal function (creatinine clearance greater than or equal to 60 mL/min) to those with renal dysfunction (creatinine clearance less than 60 mL/min). Results Notable differences in the incidence of grade ≥3 cardiotoxicity (33% of renal dysfunction patients vs.

Myelodysplastic Syndromes, Version 2.2017, NCCN Clinical Practice Guidelines in Oncology.

The myelodysplastic syndromes (MDS) comprise a heterogenous group of myeloid disorders with a highly variable disease course. Diagnostic criteria to better stratify patients with MDS continue to evolve, based on morphology, cytogenetics, and the presence of cytopenias. More accurate classification of patients will allow for better treatment guidance.

Retrospective analysis of bendamustine and rituximab use in indolent and mantle cell non-Hodgkin lymphoma based on initial starting dose.

The initial dose of bendamustine, an alkylating agent used in treating indolent lymphoma (iNHL) and mantle cell lymphoma, is variable in clinical practice. 134 patients treated with bendamustine and rituximab were evaluated for starting dosage, patient characteristics, toxicities, and clinical outcome. The starting dosage ranged from 50 to 90 mg/m.

Midostaurin, bortezomib and MEC in relapsed/refractory acute myeloid leukemia.

Targeting aberrant tyrosine kinase activity may impact clinical outcome in acute myeloid leukemia (AML). We conducted a phase I study of the tyrosine kinase inhibitor midostaurin with bortezomib alone and in combination with chemotherapy in patients with AML. Patients on dose levels 1 and 2 (DL1 & 2) received midostaurin 50 mg bid and escalating doses of bortezomib (1 to 1.

Management of patients with cytogenetically normal acute myeloid leukemia who have neither favorable nor unfavorable markers.

The presence or absence of cytogenetic and molecular abnormalities present at the time of diagnosis of acute myeloid leukemia (AML) not only provides important prognostic information, but also directs decisions regarding postremission therapy. In no other group has molecular analysis been more important than for the 40% to 50% of newly diagnosed patients in whom clonal chromosomal aberrations are not detected. Patients with cytogenetically normal (CN) AML were once considered a homogenous group, but are now classified into molecularly defined subgroups with distinct clinical outcomes.
