Abstract
OBJECTIVES NS-87/CPX-351 is a dual-drug liposomal encapsulation of cytarabine and daunorubicin. NS-87/CPX-351 exerts antileukemic action by maintaining a synergistic molar ratio of cytarabine to daunorubicin of 5:1 within the liposome while in circulation. Patients with high-risk acute myeloid leukemia (AML), which includes therapy-related AML and AML with myelodysplasia-related changes (AML-MRC), have poorer outcomes than those with other AML. METHODOLOGY This open-label phase 1/2 (P1/2) study was conducted in 47 Japanese patients aged 60-75 years with newly diagnosed high-risk AML to evaluate the pharmacokinetics, safety, and efficacy of NS-87/CPX-351. RESULTS In the 6 patients enrolled in the P1 portion, no dose-limiting toxicities (DLTs) were reported, and 100 units/m2 during the induction cycle was found to be acceptable. Cytarabine and daunorubicin had a long half-life in the terminal phase (32.8 and 28.7 h, respectively). In the 35 patients enrolled in the P2 portion, composite complete remission (CRc; defined as complete remission [CR] or CR with incomplete hematologic recovery [CRi]) was achieved in 60.0% (90% CI: 44.7-74.0) of the patients. Adverse events due to NS-87/CPX-351 were well tolerated. OUTCOMES NS-87/CPX-351 can be considered as a frontline treatment option for Japanese patients with high-risk AML.

Abstract
This open-label phase 1 study (clinicaltrials.gov, NCT03555955) assessed CPX-351 pharmacokinetics (PK) and safety in patients with hematologic malignancies with normal or impaired renal function. Patients were enrolled into three cohorts based on their creatinine clearance (CrCl): ≥90 mL/min (Cohort 1, normal renal function, n = 7), 30 to <59 mL/min (Cohort 2, moderate renal impairment, n = 8), or <30 mL/min (Cohort 3, severe renal impairment, n = 6). Patients received intravenous CPX-351 for initial induction; blood and urine samples were collected for PK analysis. The primary objective was to assess the PK parameters for cytarabine, daunorubicin, and their respective metabolites, arabinosyluracil (Ara-U) and daunorubicinol. Renal impairment did not significantly impact the cytarabine, daunorubicin, or daunorubicinol exposure, but it caused a slight increase in the Ara-U exposure. The CPX-351 side effect profile was similar in patients with impaired renal function compared to those with normal renal function. All the patients reported ≥1 treatment-emergent adverse event (TEAE), most commonly febrile neutropenia and nausea (57% each) and hyperglycemia (43%); no patients discontinued treatment due to TEAEs. These data suggest that CPX-351 dose adjustment is not required for patients with hematologic malignancies with moderate or severe renal impairment.

Abstract
Therapy-related myeloid neoplasms (t-MNs), which develop after cytotoxic, radiation, or immunosuppressive therapy for an unrelated disease, account for 7%-8% of acute myeloid leukemia (AML). Worse outcomes and consequently shortened survival are associated with t-MNs as compared with de novo AML. Therapy-related MNs are being reported with increasing frequency in successfully treated acute promyelocytic leukemia (APL), in particular, before the introduction of all-trans retinoic acid (ATRA) plus arsenic trioxide (ATO). Considering the high curability of APL, t-MNs represent one of the prognosis-limiting factors in this setting of leukemia. We report our experience with a patient who developed t-AML 15 years after treatment for APL. Treatment included three cycles of chemotherapy with CPX-351 (Vyxeos, Jazz Pharmaceuticals) followed, as in remission, by an allogeneic hematopoietic stem cell transplant. A review of available literature was also included.

Abstract
INTRODUCTION Previously, it was assumed that genetic influence played a minor role in acute myeloid leukemia (AML). Increasing evidence of germline mutations has emerged, such as DDX41 germline mutation associated with familial AML. CASE PRESENTATION A 64-year-old male patient presented with reduced exercise tolerance and shortness of breath. Following confirmation of AML diagnosis, the patient was enrolled into the AMLSG-30-18 study with a requirement for allogenic stem cell transplantation. The sister was initially selected as a fully HLA-matched donor. However, the family history showed risks for familial AML. Due to the striking family history, further diagnostic steps were initiated to detect a germline mutation. METHODS Using NGS in the patients' bone marrow AML sample, a DDX41 mutation with a VAF of 49% was detected, raising the possibility of a germline mutation. DNA from cheek swabs and eyebrows were tested for the presence of the DDX41 mutation in all siblings. RESULTS DDX41 germline mutation was detected in 5 out of 6 siblings. The sister was excluded as a related donor and the search for an unrelated donor was initiated. CONCLUSION Obtaining family history of cancer patients plays a crucial role in oncology. If a germline mutation is suspected, further family work-up should be initiated.

Abstract
Background Pediatric acute myeloid leukemia (AML) therapy is associated with substantial short- and long-term treatment-related cardiotoxicity mainly due to high-dose anthracycline exposure. Early left ventricular systolic dysfunction (LVSD) compromises anthracycline delivery and is associated with inferior event-free and overall survival in de novo pediatric AML. Thus, effective cardioprotective strategies and cardiotoxicity risk predictors are critical to optimize cancer therapy delivery and enable early interventions to prevent progressive LVSD. While dexrazoxane-based cardioprotection reduces short-term cardiotoxicity without compromising cancer survival, liposomal anthracycline formulations have the potential to mitigate cardiotoxicity while improving antitumor efficacy. This overview summarizes the rationale and methodology of cardiac substudies within AAML1831, a randomized Children's Oncology Group Phase 3 study of CPX-351, a liposomal formulation of daunorubicin and cytarabine, in comparison with standard daunorubicin/cytarabine with dexrazoxane in the treatment of de novo pediatric AML. Methods/design Children (age <22 years) with newly diagnosed AML were enrolled and randomized to CPX-351-containing induction 1 and 2 (Arm A) or standard daunorubicin and dexrazoxane-containing induction (Arm B). Embedded cardiac correlative studies aim to compare the efficacy of this liposomal anthracycline formulation to dexrazoxane for primary prevention of cardiotoxicity by detailed core lab analysis of standardized echocardiograms and serial cardiac biomarkers throughout AML therapy and in follow-up. In addition, AAML1831 will assess the ability of early changes in sensitive echo indices (e.g., global longitudinal strain) and cardiac biomarkers (e.g., troponin and natriuretic peptides) to predict subsequent LVSD. Finally, AAML1831 establishes expert consensus-based strategies in cardiac monitoring and anthracycline dose modification to balance the potentially competing priorities of cardiotoxicity reduction with optimal leukemia therapy. Discussion This study will inform diagnostic, prognostic, preventative, and treatment strategies regarding cardiotoxicity during pediatric AML therapy. Together, these measures have the potential to improve leukemia-free and overall survival and long-term cardiovascular health in children with AML.

Abstract
CPX-351, a dual-drug liposomal encapsulation of daunorubicin and cytarabine in a 1:5 molar ratio, is approved for the treatment of newly diagnosed therapy-related acute myeloid leukemia (AML) or AML with myelodysplasia-related changes. In a pivotal phase III trial, CPX-351 significantly improved overall survival compared with standard-of-care 7 + 3 chemotherapy (7 days cytarabine; 3 days daunorubicin) in adults aged 60-75 years with newly diagnosed high-risk or secondary AML (median = 9.56 months vs. 5.95 months; hazard ratio = 0.69; 95% confidence interval = 0.52-0.90; p = 0.003). Approximately 30% of patients with newly diagnosed AML have mutations in the FLT3 gene, which may be associated with poor outcomes. Here, we review the current in vitro, clinical, and real-world evidence on the use of CPX-351 in patients with AML and mutations in FLT3. Additionally, we review preliminary data from clinical trials and patient case reports that suggest the combination of CPX-351 with FLT3 inhibitors may represent another treatment option for patients with FLT3 mutation-positive AML.

Abstract
INTRODUCTION Acute myeloid leukemia (AML) treatment has primarily focused on 7 + 3 chemotherapy, but in the last decade there has been a significant increase in new therapies, mostly targeted agents, approved for the treatment of AML. We performed a comparative analysis of the unique safety profile of each of these new agents. AREAS COVERED We conducted a review of the current literature on public databases (PubMed, ClinicalTrials.gov, and U.S. Food and Drug Administration) regarding new AML drugs that were approved from 2017 to 2023. EXPERT OPINION The diagnosis of AML typically carries a poor prognosis but with an increase in the number of drugs that are now available, patients' outcomes are improving. With novel mechanisms of action, the use of these agents introduces different safety profiles, occasionally with adverse events not previously seen with standard chemotherapy or at different frequencies. An understanding of the drugs available and the safety concerns associated with each one is crucial to selecting the best available option for each patient, and early recognition and appropriate management of drug-related adverse effects.

Abstract
Therapy-related acute myeloid leukemia (t-AML) comprises 10-20% of all newly diagnosed cases of AML and is related to previous use of chemotherapy or ionizing radiotherapy for an unrelated malignant non-myeloid disorder or autoimmune disease. Classic examples include alkylating agents and topoisomerase II inhibitors, whereas newer targeted therapies such as poly (adenosine diphosphate-ribose) polymerase (PARP) inhibitors have emerged as causative agents. Typically, t-AML is characterized by adverse karyotypic abnormalities and molecular lesions that confer a poor prognosis. Nevertheless, there are also cases of t-AML without poor-risk features. The management of these patients remains controversial. We describe the causes and pathophysiology of t-AML, putting emphasis on its mutational heterogeneity, and present recent advances in its treatment including CPX-351, hypomethylating agent plus venetoclax combination, and novel, molecularly targeted agents that promise to improve the cure rates. Evidence supporting personalized medicine for patients with t-AML is presented, as well as the authors' clinical recommendations.

Abstract
CPX-351 (Europe: Vyxeos® liposomal; United States: Vyxeos®) is a dual-drug liposomal encapsulation of daunorubicin and cytarabine in a synergistic 1:5 molar ratio. In a phase 3 study in older adults with newly diagnosed, high-risk/secondary AML, CPX-351 improved the remission frequency, overall survival, and post-transplant survival versus 7 + 3. This post hoc analysis evaluated the final 5-year follow-up outcomes according to the European LeukemiaNet 2017 risk classification. CPX-351-treated patients had a higher remission frequency (adverse risk: 41% vs 26%; intermediate risk: 58% vs 39%) and longer median overall survival (adverse risk: 7.59 vs 5.52 months; intermediate risk: 11.86 vs 7.75 months) and post-transplant survival (adverse risk: 43.14 vs 7.08 months; intermediate risk: not reached vs 13.57 months) versus 7 + 3, with outcomes generally poorer among patients with adverse-risk AML. The safety profile of CPX-351 among patients with adverse-risk or intermediate-risk AML was consistent with that of the overall study population. Early mortality was lower, and hospitalization length of stay per patient-year was shorter with CPX-351 versus 7 + 3 within the adverse-risk and intermediate-risk subgroups. The favorable outcomes observed with CPX-351 in this post hoc analysis are consistent with results for the overall study population and further support the use of CPX-351 in these patients.ClinicalTrials.gov Identifier: NCT01696084.

Abstract
BACKGROUND CPX-351 was approved by the FDA in 2017 as frontline induction chemotherapy for patients aged ≥18 years with newly diagnosed acute myeloid leukemia (AML) which includes myelodysplasia-related changes (AML-MRC) and therapy-related acute myeloid leukemia (t-AML). The efficacy of CPX-351 among younger patients (aged <60 years) is currently unclear, as the large, randomized phase 3 study that led to approval of CPX-351 only included patients between the ages of 60 and 75 years. METHODS We performed a retrospective study of clinical and molecular data from adult patients with newly diagnosed AML-MRC or t-AML treated with CPX-351. Patients were divided into 2 cohorts: aged <60 years (cohort A) and aged ≥60 years (cohort B). We compared overall response rate (ORR) and median overall survival (mOS) between the cohorts. RESULTS Of 169 evaluable patients, 21.3% were in cohort A and 78.7% were in cohort B. ORR of the entire cohort was 53.3%; ORR of cohort A was 47.2% compared with 54.9% for cohort B (P = .46). Overall, 54.4% of responding patients proceeded to allogenic stem cell transplant (allo-SCT), including 52.9% of patients in cohort A and 54.8% in cohort B (P = 1.00). At a median follow-up of 24 months, mOS of the entire cohort was 16 months and was similar between cohorts A and B (18 vs. 15 months, respectively; P = .29). CONCLUSION CPX-351 resulted in similar response rates and survival outcomes among both younger and older adult patients with newly diagnosed AML-MRC or t-AML.

Abstract
Simple Summary Secondary AML (s-AML) including therapy-related acute myeloid leukemia (t-AML) and acute myeloid leukemia with myelodysplasia-related changes (AML-MRC) represent approximately one quarter of all AML cases. These AML subcategories are predominantly associated with advanced age and present a specific biologic profile including adverse genetics and a multidrug resistance phenotype, which often determine dramatically poor outcomes after conventional chemotherapy. In 2017, the FDA approved CPX-351, a liposomal formulation of cytarabine and daunorubicin at a fixed 5:1 molar ratio, for the treatment of adults with newly diagnosed t-AML and MRC-AML. Since the approval, many trials have been conducted or are still ongoing in order to assess the role of CPX-351 as frontline treatment in different AML subcategories, as a potential bridge to transplant or in combination with target therapies. In this review, we will discuss the current role of CPX-351 in treating these high-risk AML, focusing on how its use may potentially change the treatment paradigms of AML. Abstract Therapy-related acute myeloid leukemia (t-AML) and acute myeloid leukemia with myelodysplasia-related changes (AML-MRC) represent aggressive diseases characterized by a dismal prognosis if compared with de novo acute myeloid leukemia, especially in older patients. In these AML subsets, standard chemotherapy regimens produce poor response rates and unsatisfactory outcomes. Historically, conventional approaches consisted of an anthracycline combined with continuous infusion of cytarabine for 7 days, the “3+7” regimen. Several attempts have been conducted to ameliorate this combination regimen but inconsistent improvements in response rates and no significant changes in overall survival have been observed, until the recent introduction of targeted molecules. A liposomal formulation of traditional chemotherapy agents cytarabine and daunorubicin, termed CPX-351, enhances pharmacodynamics and synergistic effects through the maintenance of the optimal 5:1 molar ratio, which extends the treatment’s half-life and increases the bone marrow tropism of the drug. The use of CPX-351 in newly diagnosed AML-MRC and t-AML patients aged 60–75 years has demonstrated superior remission rates compared to conventional chemotherapy and improvements in event-free and overall survival. Recently, published data from a 5-year follow-up highlighted evidence that CPX-351 has the ability to produce and contribute to long-term remission and survival in older patients with newly diagnosed high-risk/secondary AML. Future perspectives include evaluation of dose intensification with CPX-351 in high-risk settings, combining this agent with targeted therapies, and better understanding the mechanism of improved responses in t-AML and AML-MRC. In this review, we will examine the role of CPX-351 inside the new AML therapeutic scenario and how its employment could potentially modify the treatment algorithm of high-risk and elderly patients with AML

Abstract
PURPOSE OF REVIEW Treatment of elderly patients with acute myeloid leukemia is a known challenge for hematologists due to patient diversity, heterogeneous disease biology, and a rapidly evolving treatment landscape. Here, we highlight the importance of determining fitness, review the latest therapeutic developments, and discuss clinical scenarios to provide guidance on individualized treatment for older AML patients. RECENT FINDINGS Several factors, like age, performance status, and comorbidities, play a role in fitness and are associated with outcome. Comorbidity scoring systems and geriatric assessments are tools to help physicians select the most appropriate treatment for each patient. The addition of venetoclax, targeted therapy with IDH1/2 and FLT3 inhibitors, and enhanced formulas of existing drugs like CPX-351 and oral azacitidine have improved responses and outcomes. New drugs and combination therapies have increased the therapeutic options for elderly AML patients but determination of fitness and disease biology is essential to select patient-tailored treatments.

Abstract
INTRODUCTION Acute myeloid leukemia (AML) is a rare blood cancer with a poor prognosis. Recently, targeted drugs have improved survival both in the elderly and in fit patients. However, as monthly costs of targeted agents are high, regulatory bodies often impose restrictions on their use. AREAS COVERED The authors review the value-for-cost of targeted drugs such as gemtuzumab ozogamycin, CPX-351, midostaurin, gilteritinib, glasdegib, venetoclax, oral azacytidine and enasidenib used to treat adult AML. EMBASE and TRIP databases, together with authority websites were searched for technology assessments. Add-on drugs, namely midostaurin and gemtuzumab ozogamycin, have been reported to have the best pharmacoeconomic profile for newly diagnosed fit patients with FLT3 mutation or favorable/intermediate cytogenetics, since allogeneic transplant rates were stable or reduced. Most of the other drugs, on the other hand, did not achieve highly favorable cost-for-benefit, due to a poor absolute survival gain and/or increased transplant rates. EXPERT OPINION The cost of most targeted therapies for AML in unfit patients seems unfair in comparison to the absolute survival advantage provided in fit patients. Point of cure and transplant outcomes should be standardized to allow comparability among the models.

Abstract
A patient with a therapy-related acute myeloid leukaemia (AML), NPM1mut, and FLT3-ITD+ was treated with induction and consolidation with CPX-351, obtaining a complete response (CR) but minimal residual disease persisted positive. Later, she complained progressive burning leg pain, weakening of the right hand and leg muscles, associated with absence of osteotendinous leg reflexes. Examination of cerebrospinal fluid (CSF) showed a meningeal relapse of AML. Moreover, a magnetic resonance imaging (MRI) showed 2 right meningeal implants of myeloid sarcoma and bone marrow revealed haematologic relapse of disease. She was treated with medicated lumbar punctures (LPs) followed by an FLA-Ida scheme, and she achieved a 2nd CR. Unfortunately, the patient developed hyperleucocytosis and reappearance of meningeal myeloid sarcoma at MRI. For this reason, a monotherapy with gilteritinib (an FLT3 inhibitor) was started: after 3 months of therapy, central nervous system (CNS)-disease shrunken and then faded, while AML in the bone marrow achieved only a partial response. This is the 1st report of a positive biological effect of gilteritinib on CNS (meningeal) myeloid sarcoma. There are no studies of gilteritinib concentration into CSF and penetration of gilteritinib into the blood-brain barrier should be further studied, given the paucity of drugs active on CNS relapse of AML. In patients receiving CPX-351 only, diagnostic LP should be considered after induction.

Abstract
PURPOSE OF REVIEW Despite recent advances in the treatment of de novo acute myeloid leukemia (AML), AML arising from antecedent chronic myelomonocytic leukemia (CMML) continues to have dismal outcomes. While the unique biological drivers of CMML and subsequent leukemic transformation (LT) have been revealed with advances in molecular characterization, this has not yet translated to the bedside. Here, we review these biologic drivers, outcomes with current therapies, and rationale avenues of future investigation specifically in blast phase CMML (CMML-BP). RECENT FINDINGS CMML-BP outcomes are studied as an aggregate with more common categories of AML with myelodysplasia-related changes (AML-MRCs) or the even broader category of secondary AML (sAML), which illustrates the crux of the problem. While a modest survival advantage with allogeneic hematopoietic stem cell transplant exists, the difficulty is bridging patients to transplant and managing patients that require an allograft-sparing approach. Limited data suggest that short-lived remissions can be obtained employing CPX-351 or venetoclax-based lower intensity combination therapy. Promising future strategies include repurposing cladribine, exploiting the supportive role of dendritic cell subsets with anti-CD123 therapies, MCL-1 inhibition, dual MEK/PLK1 inhibition, FLT3 inhibition in RAS-mutated and CBL-mutated subsets, and immune therapies targeting novel immune checkpoint molecules such as the leukocyte immunoglobulin-like receptor B4 (LILRB4), an immune-modulatory transmembrane protein restrictively expressed on monocytic cells. The successful management of an entity as unique as CMML-BP will require a cooperative, concerted effort to design and conduct clinical trials dedicated to this rare form of sAML.

Abstract
PURPOSE OF REVIEW With the recent approval of multiple new drugs for the treatment of acute myeloid leukemia (AML), the relevance of conventional treatment approaches, such as daunorubicin and cytarabine ("3+7") induction chemotherapy, has been challenged. We review the AML risk stratification, the efficacy of the newly approved drugs, and the role of "3+7". RECENT FINDINGS Treatment of AML is becoming more niched with specific subtypes more appropriately treated with gemtuzumab, midostaurin, and CPX-351. Although lower intensity therapies can yield high response rates, they are less efficient at preventing relapses. The only curative potential for poor-risk AML is still an allogeneic stem cell transplant. The number of AML subtypes where 3+7 alone is an appropriate therapeutic option is shrinking. However, it remains the backbone for combination therapy with newer agents in patients suitable for intensive chemotherapy.

Abstract
Background Acute myeloid leukemia (AML) with antecedent hematological disease (s-AML) and treatment-related AML (t-AML) predicts poor prognosis. Intensive treatment protocols of those high-risk patients should consider allogeneic stem cell transplantation (allo-HSCT) in first complete remission (CR). Despite allo-HSCT, relapse rate remains high. Induction chemotherapy with liposomal cytarabine and daunorubicin (CPX-351) has been approved for patients with AML with myeloid-related changes (AML-MRC) or t-AML based on improved survival and remission rates compared to standard 7 + 3 induction. Patients and methods 110 patients with newly diagnosed s-AML or t-AML at a university hospital were analyzed retrospectively. Median age was 62 years (24–77 years). A total of 65 patients with s-AML after MDS (59%) and 23 patients (20.9%) with t-AML were included. Induction chemotherapy consisted of intermediate-dosed cytarabine (ID-AraC) in combination with idarubicin (patients up to 60 years) or mitoxantrone (patients over 60 years). In patients subsequently undergoing allo-HSCT, reduced conditioning regimens (RIC) were applied prior to transplantation in 47 of 62 patients (76%). Results Induction chemotherapy with ID-AraC resulted in an overall response rate of 83% including complete remission (CR/CRi) in 69 patients (63%) with a low rate of early death (2.7%). Most relevant non-hematologic toxicity consisted of infectious complications including sepsis with need of intensive care treatment in five patients (4.5%) and proven or probable invasive fungal disease in eight patients (7.2%). Relapse-free survival (RFS), event-free survival (EFS) and overall survival (OS) of the whole cohort were 19 months (0–167), 10 months (0–234) and 15 months (0–234), respectively (p < 0.0001). A significant improvement of OS was observed in patients who underwent allo-HSCT compared to those without subsequent allo-HSCT: 9 vs. 46 months, p < 0.0001. Rate of transplantation-related mortality (TRM) in the early phase post allo-HSCT was low (0.9% at day 30 and 1.8% at day 90, respectively). RIC conditioning results in OS rate of 60% after 60 months post allo-HSCT (median OS not reached). Conclusion S-AML and t-AML patients receiving induction chemotherapy with intermediate-dosed cytarabine showed satisfactory response rate and consolidation therapy with allo-HSCT after full or reduced-intensity conditioning further improved survival in these patients with similar outcome as reported for CPX-351.

Abstract
Liposomal daunorubicin/cytarabine (CPX-351) gained FDA approval for secondary AML after demonstrating improved outcomes over daunorubicin and cytarabine (7 + 3). A number of study limitations prompted a comparison of safety/efficacy of CPX-351 against regimens containing a purine analogue and high-dose cytarabine (HIDAC). This retrospective study compared complete response rates with/without count recovery (CR/CRi) between HIDAC-based regimens and CPX-351 in 169 patients with newly diagnosed sAML. The CR/CRi rate was 62.7% in the HIDAC-based therapy arm vs. 47.9% in the CPX-351 arm (p = 0.002 [one-sided for non-inferiority]). Median time to absolute neutrophil and platelet count recovery was shorter after HIDAC-based therapy (18 and 23 days, respectively) compared to CPX-351 (36 and 38 days; p < 0.001). Median overall survival was 9.8 months in the HIDAC-based group and 9.14 months in the CPX-351 group. 30-day mortality was greater with CPX-351 (8.5%) compared to HIDAC-based (1.3%; p = 0.039). These results reveal comparable efficacy and favorable safety with HIDAC-based regimens.

Abstract
PURPOSE OF REVIEW Secondary AML (s-AML) encompasses a distinct subgroup of AML with either therapy-related AML or AML arising from preexisting myeloid neoplasms. Despite recent advances in the treatment armamentarium of AML, outcomes remain poor in s-AML. The purpose of this review is to highlight distinct characteristics, prognostic factors, and treatment options for patients with s-AML. Further, we focus on a distinctly poor-risk subgroup of s-AML with previous exposure to hypomethylating agents (HMAs) and describe ongoing clinical trials in this patient population. RECENT FINDINGS CPX-351 (liposomal daunorubicin and cytarabine) is the first drug approved for s-AML and represents an advancement in the management of fit patients with this subtype of AML. Despite incremental improvement in remission rates and survival, long-term survival remains poor. Patients who have received prior HMAs for antecedent MDS rarely benefit from CPX-351 or other cytotoxic chemotherapy regimens. The approval of venetoclax in combination with azacitidine has led to a paradigm shift in the management of newly diagnosed older unfit AML patients; however, patients with s-AML and prior HMA therapy were excluded from the landmark randomized phase 3 study. Several early phase clinical trials with both low- and high-intensity therapies are ongoing for s-AML patients, though prior HMA exposure limits inclusion in many of these studies that include HMAs. Patients with s-AML previously treated with an HMA have dismal outcomes with standard therapeutic options and are under-represented in clinical trials. Trials investigating novel therapeutic options in this population are critically needed.

Abstract
Objectives Acute myeloid leukemia (AML) with myelodysplasia-related changes (AML-MRC) represents a high-risk and somewhat diverse subtype of AML, and substantial confusion exists about the pathologic evaluation needed for diagnosis, which can include the patient’s clinical history, cytogenetic analysis, mutational analysis, and/or morphologic evaluation. Treatment decisions based on incomplete or untimely pathology reports may result in the suboptimal treatment of patients with AML-MRC. Methods Using a PubMed search, diagnosis of and treatment options for AML-MRC were investigated. Results This article reviews the current diagnostic criteria for AML-MRC, provides guidance on assessments necessary for an AML-MRC diagnosis, summarizes clinical and prognostic features of AML-MRC, and discusses potential therapies for patients with AML-MRC. In addition to conventional chemotherapy, treatment options include CPX-351, a liposomal encapsulation of daunorubicin/cytarabine approved for treatment of adults with AML-MRC; targeted agents for patients with certain mutations/disease characteristics; and lower-intensity therapies for less fit patients. Conclusions Given the evolving and complex treatment landscape and the high-risk nature of the AML-MRC population, a clear understanding of the pathology information necessary for AML-MRC diagnosis has become increasingly important to help guide treatment decisions and thereby improve patient outcomes.

Abstract
Acute myeloid leukemia with myelodysplasia-related changes (AML-MRC) and treatment-related acute myeloid leukemia (tAML) after chemotherapy or radiation therapy for other neoplasms are associated with poor outcomes. CPX-351, a dual-drug liposomal encapsulation of daunorubicin and cytarabine, has been shown to improve outcomes in AML-MRC and tAML compared with standard 7+3 regimens. Here we report the cases of four consecutive patients with AML-MRC or tAML who received CPX-351 as outpatient induction therapy immediately followed by allogeneic hematopoietic stem cell transplantation (allo-HSCT). Two patients received allo-HSCT in remission (one in complete remission and one in partial remission) and two patients received allo-HSCT in aplasia (one at 11 days and one at 52 days after the start of induction therapy with CPX-351). With a median follow-up of 188 days after allo-HSCT, all but one patient are alive and two are in remission. Further studies will help define and expand the role of CPX-351 in the treatment of AML-MRC and tAML, especially in patients expected to undergo allo-HSCT.

Abstract
CPX-351, a liposomal encapsulation of cytarabine and daunorubicin at a synergistic 5:1 molar ratio, is indicated for adults with newly diagnosed, therapy-related acute myeloid leukemia or acute myeloid leukemia with myelodysplasia-related changes. In preclinical species, this article demonstrated (1) similar release of cytarabine and daunorubicin by CPX-351 in plasma; (2) similar patterns of metabolism of cytarabine and daunorubicin following administration of CPX-351 versus non-liposomal cytarabine/daunorubicin combination; (3) prolonged tissue exposure to CPX-351; (4) dramatically different tissue distribution of cytarabine and daunorubicin following administration of CPX-351 versus non-liposomal combination (tissue:plasma ratios generally <1 versus >1, respectively); and (5) dramatically lower unbound plasma and tissue concentrations of cytarabine and daunorubicin following administration of CPX-351 versus non-liposomal combination. Together, these results provide insight into the safety profile of CPX-351, as well as mechanisms that drive the improved efficacy observed for CPX-351 versus the conventional 7 + 3 cytarabine/daunorubicin regimen in clinical studies.

Abstract
Acute myeloid leukemia (AML) with myelodysplasia-related changes (AML-MRC) is a distinct biologic subtype of AML that represents 25-34% of all AML diagnoses and associates with especially inferior outcomes compared to non-MRC AML. Typically, patients with AML-MRC experience low remission rates following intensive chemotherapy and a median overall survival of merely 9-12 months. In light of these discouraging outcomes, it has become evident that more effective therapies are needed for patients with AML-MRC. Liposomal daunorubicin-cytarabine (CPX-351) was approved in 2017 for adults with newly diagnosed AML-MRC and those with therapy-related AML (t-AML), and remains the only therapy specifically approved for this patient population. Other studies have also demonstrated the efficacy of the hypomethylating agent (HMA) azacitidine as upfront therapy for AML-MRC patients, which, to date, is the most common treatment employed for patients unable to tolerate the more intensive CPX-351. HMAs and venetoclax combinations have also been evaluated, but additional studies utilizing these agents in this specific subgroup are needed before conclusions regarding their role in the therapeutic armamentarium of AML-MRC patients can be reached. Currently, many studies are ongoing in attempts to further improve outcomes in this historically ill-fated patient group.

Abstract
Aims: Treatment of acute myeloid leukemia (AML) requires significant healthcare resource utilization (HRU), including lengthy hospitalizations. In a phase 3 study (NCT01696084), CPX-351 (Vyxeos) showed significant benefits to overall survival and complete remission versus conventional 7 + 3 cytarabine/daunorubicin. This analysis evaluated HRU in patients aged 60-75 years with newly diagnosed high-risk/secondary AML treated with CPX-351 versus 7 + 3 in the phase 3 study.Materials and methods: Patients were randomized to receive up to two induction cycles with CPX-351 or 7 + 3. Responders could receive up to two cycles of consolidation. To normalize HRU to length of treatment, patients were assessed on a per patient-year (PPY) basis. HRU analyses included hospital and intensive care unit (ICU) stays, anti-infective use, transfusions, and white blood cell colony-stimulating factor (CSF).Results: The median (range) total duration of hospitalization was 39 (3-110) days with CPX-351 (n = 153) and 32 (2-83) days with 7 + 3 (n = 151); the estimated durations of hospitalization PPY were 198.4 and 240.5 days, respectively. The median (range) total duration of ICU stays was 0 (0-45) days with CPX-351 and 0 (0-17) days with 7 + 3; the estimated durations of ICU stays PPY were 6.7 and 10.5 days, respectively. When comparing supportive care use during CPX-351 and 7 + 3 treatment, the estimated number PPY of bags of platelets used (24.6 vs 26.9, respectively), bags of packed red blood cells used (13.0 vs 13.9), days of anti-infectives (162.0 vs 159.2), and days of CSF (4.0 vs 2.4) were not notably different.Limitations: This clinical study analysis may not represent real-world HRU patterns or be generalizable to a broader AML population.Conclusions: These PPY data, showing shorter durations of hospitalization and similar use of supportive care with CPX-351 versus 7 + 3, suggest CPX-351 is not associated with increased HRU in older patients with newly diagnosed high-risk/secondary AML.

Abstract
Isocitrate dehydrogenase 1 and 2 (IDH1 and IDH2) interfere with cellular metabolism contributing to oncogenesis. Mutations of IDH2 at R140 and R172 residues are observed in 20% of acute myeloid leukemias (AML), and the availability of the IDH2 inhibitor Enasidenib made IDH2 mutational screening a clinical need. The aim of this study was to set a new quantitative polymerase chain reaction (PCR) technique, the drop-off digital droplet PCR (drop-off ddPCR), as a sensitive and accurate tool for detecting IDH2 mutations. With this technique we tested 60 AML patients. Sanger sequencing identified 8/60 (13.5%) mutated cases, while ddPCR and the amplification refractory mutation system (ARMS) PCR, used as a reference technique, identified mutations in 13/60 (21.6%) cases. When the outcome of IDH2-mutated was compared to that of wild-type patients, no significant difference in terms of quality of response, overall survival, or progression-free survival was observed. Finally, we monitored IDH2 mutations during follow-up in nine cases, finding that IDH2 can be considered a valid marker of minimal residual disease (MRD) in 2/3 of our patients. In conclusion, a rapid screening of IDH2 mutations is now a clinical need well satisfied by ddPCR, but the role of IDH2 as a marker for MRD still remains a matter of debate.

Abstract
Relapse is still a common scenario in acute myeloid leukemia (AML) treatment and occurs in 40–50% of younger and the great majority of elderly patients. The prognosis in relapsed AML patients is generally poor but depends largely on the timing of relapse (early versus late) and the possibility of allogeneic hematopoietic stem cell transplantation (HSCT). At the time of relapse, we again perform a mutational screening and cytogenetic analysis in all AML patients as clonal evolution of disease is frequent. Clinical trials should be first priority in all relapsed patients. In fit patients without prior transplant, we aim to perform HSCT after salvage therapy. In AML patients relapsing after HSCT and good performance status, intensive therapy can be considered with subsequent cellular therapy such as donor lymphocyte infusion (DLI) or a second HSCT. However, less than 20% of these patients are alive after 5 years. For those patients that are unfit, the therapeutic aim is to prolong life with acceptable quality of life. Here, hypomethylating agents (HMA), low-dose AraC (LDAC), and solely cytoreductive therapy with hydroxurea are options depending on first-line therapy. For those patients that have not been treated with venetoclax in first line, the combination therapy of venetoclax with demethylating agents achieves encouraging response rates. Venetoclax is currently also studied in combination with intensive salvage therapy. Importantly, for patients with isocitrate dehydrogenase (IDH) 1/2–mutated AML, ivosidenib, an IDH1 inhibitor, and enasidenib, an IDH2 inhibitor, present well-tolerated options in the setting of refractory or relapsed (r/r) disease even in elderly and heavily pre-treated patients with response rates of 30–40%. Both substances have been approved by the U.S. Food and Drug Administration (FDA) for r/r AML patients with IDH1/2 mutations (but not yet by the European Medicines Agency (EMA)). For patients with FMS-like tyrosine kinase 3 (FLT3) mutations, treatment with the selective FLT3 inhibitor gilteritinib is well tolerated and leads to improved outcome compared with standard salvage therapy. The approval has been granted by the FDA and the EMA. Generally, we would recommend targeted therapy for IDH1/2- and FLT3-mutated AML if available. In order to improve outcome in relapsed AML, it will be important to intelligently combine novel substances with each other as well as chemotherapy in prospective clinical trials. The development of therapies with bispecific antibodies or chimeric antigen receptor T cells (CAR-T) are still in early development.

Abstract
Acute myeloid leukemia (AML) is a heterogenous disease that predominantly affects older adults. Despite recent advances in therapy, outcomes for AML with conventional induction chemotherapy are worse with advanced age. CPX-351 is a liposomal encapsulated formulation of cytarabine and daunorubicin in a 5:1 molar ratio that has been demonstrated to deliver synergistic ratiometric dosing of these drugs in pre-clinical studies. Early phase studies noted the encapsulated formulation of CPX-351 led to the extended duration of detectable cytarabine and daunorubicin levels compared to conventional chemotherapy, which may contribute to prolonged cytopenias. Further clinical trials demonstrated the safety and efficacy of CPX-351 in older adults, particularly those with secondary AML (sAML). The treatment landscape of AML is evolving with the recent approval of multiple therapeutic agents. Further studies are indicated to evaluate the role of CPX-351 potentially in combination with other targeted drugs.

Abstract
Prospective evidence for management of therapy-related acute myeloid leukemia (t-AML) is limited, with evidence extrapolated from major AML trials. Optimal treatment is challenging and needs consideration of patient-specific, disease-specific, and therapy-specific factors. Clinical trials are recommended, especially for unfit patients or those with unfavorable cytogenetics or mutations. CPX-351 as an upfront intensive chemotherapy is preferred for fit patients; venetoclax with decitabine or azacitidine is an option for patients unfit for intensive chemotherapy. Hematopoietic cell transplant, the only curative option, should be offered to eligible patients with intermediate or unfavorable t-AML or patients with good-risk AML with minimal residual disease. Ongoing clinical trials focusing on treatment of t-AML, including targeted agents and immunotherapy, bode well for the future.

Abstract
OBJECTIVE To provide a comprehensive review of evidence-based data on the newly approved therapeutic agents in acute myeloid leukemia (AML) with regards to appropriate indications for use, efficacy, and safety. DATA SOURCES Published clinical trials and observational studies. CONCLUSION Optimal treatment decisions for AML should be personalized based on individual patients' performance status, disease risk as determined by mutational profile, response status, and prior therapies received. While the treatment options have expanded, several questions remain regarding appropriate patient selection, long-term efficacy and safety of these agents, and sequencing of therapies among available options. IMPLICATIONS FOR NURSING PRACTICE Nurses need to be familiar with the peculiarities of the administration regimens of newer AML therapies, adopt formal monitoring strategies for side effects that are unique to these agents, and develop a framework to facilitate timeliness of follow-up and monitoring while on these therapies.

Abstract
In recent years, several drugs-including midostaurin, gilteritinib, and gemtuzumab ozogamicin, to name a few-have been approved or reapproved in the United States to treat patients with acute myeloid leukemia (AML). Yet survival rates for younger patients had improved with chemotherapy alone even before the approvals of these new agents. This begs the question whether the new therapies will actually have a positive impact on survival. The 5-year survival rate for older patients has also risen, again without the addition of these new agents. The challenge will be to incorporate new therapies and use them where they will have the greatest impact-major work for clinicians and researchers alike.

Abstract
For decades, the standard induction for patients with acute myeloid leukemia (AML) has been the combination of cytarabine with anthracycline (7 + 3 regimen). In August 2017 the US FDA approved CPX-351 (vyxeos), a liposomal formulation of cytarabine and daunorubicin at a fixed 5:1 molar ratio, for the treatment of adults with newly diagnosed AML with myelodysplasia-related changes (AML-MRC) and therapy-related AML (t-AML). This is the first approved treatment specifically for patients with this subgroup of AML. The approval was based on findings from a multicenter, randomized, open-label, phase III study of CPX-351 Versus 7 + 3 in patients 60-75 years old with newly diagnosed AML-MRC or t-AML. In this study CPX-351 had a higher median OS than 7 + 3 (9.56 vs 5.95 months, HR 0.69; 95% CI: 0.52 to 0.90, p = 0.005). In this profile, we review preclinical and clinical data, and discuss limitations and future directions with CPX-351 use in AML.

Abstract
The mainstay of therapeutic modalities of acute myeloid leukemia (AML) includes intensive chemotherapies and allogeneic hematopoietic cell transplantation. The gold standard of the induction treatment is a regular dose of cytarabine plus anthracycline, and several courses of consolidation therapy are administered. Allogeneic hematopoietic cell transplantation is employed in patients with intermediate-poor risks. No new drugs have been introduced to the treatment of AML for nearly 30 years. However, in 2017, the US Food and Drug Administration approved four novel drugs for treating AML: FLT3 inhibitor midostaurin, IDH2 inhibitor enasidenib, liposomal cytarabine-daunorubicin CPX-351, and revived antibody-drug conjugate gemtuzumab ozogamicin. In Japan, several new agents are also undergoing clinical trials, including Bcl-2 inhibitor venetoclax, CDK9 inhibitor alvocidib, smoothened (SMO) inhibitor glasdegib, hypomethylating agents guadecitabine and azacitidine, NEDD8 inhibitor pevonedistat, and FLT3 inhibitors quizartinib and gilteritinib. These agents will be incorporated into the conventional 7+3 regimen or combined with hypomethylating agents or low-dose cytarabine to improve the therapeutic outcomes of AML.

Abstract
A recent phase 3 trial showed that outcome of older patients with secondary acute myeloid leukemia (AML) may be improved by a liposomal encapsulation of cytarabine and daunorubicin (CPX‐351). This phase 3 study represents a unique example of prospective data in this rare subgroup providing basis for comparison with real life data. Here, we retrospectively assessed characteristics and outcome of patients aged 60‐75 years with secondary or therapy‐related AML in real life. Out of 218 patients that fulfilled CPX‐351 study criteria, 181 patients (83.0%) received antileukemic treatment either intensive chemotherapy (n = 121) or hypomethylating agents (HMA, n = 60). As compared with patients treated by chemotherapy, HMA‐treated patients were older, had lower WBC, more often AML with antecedent myelodysplastic syndrome and adverse cytogenetic risk. In chemotherapy‐treated patients, the complete response rate was 69%, median overall survival (OS) was 11 months whereas 3‐year and 5‐year OS was 21% and 17%, respectively. In HMA‐treated patients, the complete response rate was 15%, median OS was 11 months whereas 3‐year and 5‐year OS was 15% and 2%, respectively. In conclusion, although outcome of older patients with high‐risk AML is very poor, a significant proportion of patients treated by standard intensive chemotherapy but not HMA are long‐term survivors.

Abstract
Introduction: Topoisomerase II inhibitors have long been used in the frontline and as salvage therapy for AML, with daunorubicin and idarubicin being prototypical agents in this therapeutic class, classically in combination with nucleoside analogs, e.g. cytarabine. Most recently, several other compounds from this drug class have or are being investigated. Areas covered: The current paper reviews older and newer topoisomerase II inhibitors in clinical development for the treatment of AML. The authors discuss the clinical use of these agents, current trials involving them as well as their safety profile. Important side effects of these medications including therapy-related AML (t-AML) are also covered. Expert opinion: Topoisomerase II inhibitors have helped improve outcomes in AML. Recently, the FDA approved several agents including CPX-351 for the treatment of secondary and t-AML. CPX-351 may have applicability in other high-risk myeloid diseases. Future directions include a combination of these agents with other targeted therapies. Finally, the authors believe that small molecule inhibitors, such as venetoclax and possibly immunotherapy options could also be incorporated to our treatment paradigm in selected patients.

Abstract
Combination regimens are a standard of care for many cancers. However, components of such regimens are typically first developed individually and subsequently combined using strategies to minimize toxicity. Little or no consideration is given to strategies that potentially maximize efficacy. In contrast, CPX-351 (Vyxeos®) is a dual-drug liposomal encapsulation of cytarabine and daunorubicin that was rationally designed to improve efficacy over the traditional 7+3 cytarabine/daunorubicin chemotherapy regimen for patients with acute myeloid leukemia (AML). The notable clinical efficacy of CPX-351 is achieved through maintenance of a synergistic 5:1 molar ratio of cytarabine and daunorubicin within the liposome after intravenous injection. The CPX-351 liposome, which is formulated to contain bilayers of distearoylphosphatidylcholine, distearoylphosphatidylglycerol, and cholesterol at a 7:2:1 molar ratio and remains in a gel phase at body temperature, provides stability without polyethylene glycol, controlled release of cytarabine and daunorubicin, limited systemic drug distribution, and preferential internalization within malignant myeloblasts in the bone marrow via active uptake of liposomes into cytoplasmic vacuoles. Thus, the CPX-351 liposome protects cytarabine and daunorubicin from metabolism and elimination, while overcoming pharmacokinetic differences between the two agents. In clinical studies, these liposome properties markedly increased the elimination half-life of CPX-351 versus free cytarabine and daunorubicin and maintained a synergistic drug ratio for over 24 hrs after administration. Preferential uptake of liposomes by leukemia cells suggests that relatively large amounts of cytarabine and daunorubicin enter malignant cells via liposomes, potentially bypassing P-glycoprotein-based efflux pumps, which are important mediators of chemotherapy resistance, and contribute to the rapid clearance of leukemia cells from the circulation and bone marrow. These pharmacologic advantages, a direct consequence of properties of the encapsulating liposome, may explain the efficacy of CPX-351 in patients with newly diagnosed high-risk/secondary AML and the reduced drug exposure in off-target tissues that contribute to a manageable safety profile.

Abstract
Initial therapy for acute myeloid leukemia (AML) remained stagnant for approximately four decades despite advances in improved understanding of pathogenesis and prognostication of the disease. Treatment has typically consisted of an anthracycline combined with continuous infusion of cytarabine for 7 days, the "7 + 3" regimen. Attempts have been made to improve on this regimen with modest improvements in response rates but no change in overalll survival, until the recent introduction of mutation-specific agents. However, the re-vamping of the delivery of both daunorubicin and cytarabine in a liposomal encapsulation, known as CPX-351, did show improvements of overall survival compared to traditional 7 + 3 in newly diagnosed secondary and therapy-related AML in patients aged 60-75. This led to the Food and Drug Administration (FDA) approval of the agent for both of these subtypes of AML in August of 2017. Herein we will review the rationale and preclinical development of CPX-351 and discuss the pivotal studies that led to its FDA approval.

Abstract
In April 2018, an updated version of the previously published guidelines on acute myeloid leukemia (AML) from 2010 and 2017 was released. A revision was necessary because of two positive aspects: First, new data and insights on risk stratification and monitoring, and second, the clinical development and approval of new agents. The modified genetic risk classification allows a more precise distinction of different diagnostic groups and consequently a better matched post-remission treatment. The availability of new targeted drugs such as inhibitors turns genetic analyses from a mere prognostic tool into an instrument for treatment decisions. Several recently approved agents expand the treatment options for AML and raise hope for an improved prognosis and cure in the future.

Abstract
BACKGROUND Liposomal formulation of anthracyclines provide better systemic and organ-specific tolerance, with potential for less local tissue damage during extravasation. Several small series have reported that most liposomal anthracycline extravasations are consistent with irritant injury without tissue necrosis. There have been no reports published regarding the clinical effects of extravasation of liposomal cytarabine-daunorubicin (CPX-351). CASE REPORT The patient received CPX-351 for relapsed acute myelogenous leukemia via a left chest wall port-a-catheter. The catheter became dislodged. Once symptoms developed, the infusion was discontinued, with observations demonstrating an 8-cm region of edema, warmth, no erythema, and no drainage. Limited supportive management was performed. Physical examination the following day demonstrated no evidence of necrosis, and erythema resolved completely without additional intervention. CONCLUSION CPX-351 extravasation behaving as an irritant is consistent with the reports of other liposomal anthracyclines.

Abstract
Acute myeloid leukemia (AML) is a complex hematological disease characterized by genetic and clinical heterogeneity. Recent advances in the understanding of AML pathogenesis have paved the way for the development of new agents targeting specific molecules or mechanisms that contribute to finally move beyond the current standard of care, which is "3 + 7" regimen. In particular, new therapeutic options such as targeted therapies (midostaurin and enasidenib), monoclonal antibodies (gemtuzumab ozogamicin), and a novel liposomal formulation of cytarabine and daunorubicin (CPX-351) have been recently approved, and will be soon available for the treatment of adult patients with AML. In this review, we will present and describe these recently approved drugs as well as selected novel agents against AML that are currently under investigation, and show the most promising results as monotherapy or in combination with chemotherapy. The selection of these emerging treatments is based on the authors' opinion.

Abstract
Older adults with acute myeloid leukemia (AML) traditionally have very poor survival outcomes. Those who receive only supportive care have worse overall survival than those who undergo treatment, regardless of treatment type, and improvements in overall survival in the last several decades are largely attributable to the increasing decision to treat rather than offer only supportive care. However, there are a few newer agents that appear promising; these include CPX-351 (a liposomal product with cytarabine and daunorubicin), glasdegib (a selective Hedgehog signaling pathway inhibitor), and venetoclax (potent small molecule inhibitor of BCL2). A systematic review and meta-analysis is being completed to help clinicians optimize standard therapies for older AML patients.

Abstract
CPX-351, a liposomal formulation co-encapsulating cytarabine and daunorubicin (DNR) in a synergistic 5:1 M ratio, has shown favourable response in newly diagnosed elderly high-risk AML. This study assessed intracellular ara-CTP levels following in vitro exposure of human immortalised leukaemic cell lines and primary AML blasts to CPX-351, and investigated fludarabine potentiation of intracellular ara-CTP formation from CPX-351. Comparison of intracellular handling of CPX-351 to cytarabine in HL-60 cells indicated slower conversion to ara-CTP for CPX-351, but equivalent cytotoxicity to cytarabine and combined DNR/cytarabine (DA) at 48 h, mostly likely reflecting the need for intracellular liposome processing to release encapsulated drugs. Further assessment demonstrated cytotoxicity of CPX-351 to be superior to DA at 48 and 72 h in cytarabine-resistant THP-1 cells (p < 0.001), and this effect could not be inhibited upon blockade of human equilibrative nucleoside transporter (hENT) function with dipyridamole. Assessment of Flu-CPX in primary blasts from presentation AML patients (n = 5) demonstrated a more rapid and pronounced potentiation of ara-CTP from CPX-351 than in immortalised cell lines, with 4/5 patients showing significant increases in ara-CTP, notably for those that went on to fail induction and relapse treatment in vivo (n = 3). This suggests a favourable impact on patient outcome from Flu-CPX.

Abstract
Despite increasing understanding of the pathobiology of acute myeloid leukemia (AML), outcomes remain dismal particularly for patients over the age of 60 years, a population enriched for therapy-related AML (tAML) and secondary AML (sAML). For decades, the standard of care for AML has been the combination of cytarabine and daunorubicin, typically delivered in combination as “7 + 3” induction. In 2017, a liposomal-encapsulated combination of daunorubicin and cytarabine (CPX-351, Vyxeos) was approved by the US Food and Drug Administration (FDA) for use in the treatment of newly diagnosed tAML or AML with myelodysplasia-related changes (AML-MRCs). CPX-351 was designed to deliver a fixed 5:1 molar ratio of cytarabine and daunorubicin, respectively, based on the hypothesis that ratiometric dosing may be more effective than the delivery of either drug at their maximum tolerated dose. In a Phase III trial of older patients with sAML aged 60–75 years, CPX-351 was compared to “7 + 3” and was associated with a higher overall survival, event-free survival, and higher rates of complete remission (CR) and CR with incomplete hematologic recovery (CRi). These data were the basis for the approval of this new drug for use in the treatment of AML, but questions remain regarding how to best administer this agent across AML subgroups. Future directions include evaluating dose intensification with CPX-351, combining this agent with targeted therapies, and better understanding the mechanism of improved responses in tAML and AML-MRC, two entities that are historically less responsive to cytotoxic agents. In summary, CPX-351 offers an exciting new change to the landscape of AML therapy.

Abstract
Patients with secondary acute myeloid leukemia (sAML) have poor outcomes, with CR/CRi rates of 25-35% with standard 7 + 3 induction chemotherapy, while single center non-comparative analyses suggest promising outcomes with FLAG. We conducted a single-center, retrospective cohort study assessing outcomes in treatment-naïve patients with sAML treated with fludarabine, high-dose cytarabine, and granulocyte colony-stimulating factor (FLAG, n = 40) compared with 7 + 3 (n = 66). Median patient age was 63 years (range: 27-82) in the FLAG group and 60 years (range: 21-76) in the 7 + 3 group (P = 0.968). Patients treated with FLAG achieved higher overall response rates (CR + CRi + MLFS) compared to 7 + 3 (70% vs. 48%, P = 0.043). FLAG was well tolerated, with only one induction death (30-day mortality rate, 3% vs. 8%, P = 0.405) and no cases of cerebellar toxicity. Duration of neutropenia was significantly shorter with FLAG (median 16 vs. 23 days, P < 0.001). Half of the FLAG-treated patients proceeded to consolidative therapy compared with only 27% of those who received 7 + 3 (P = 0.022). Overall survival was comparable between groups (8.5 mos, FLAG vs. 9.1 mos, 7 + 3; P = 0.798). Thus, FLAG may represent a low-cost treatment strategy in sAML that produces higher response rates and promising survival outcomes with minimal treatment-related toxicity. Further studies are required to prospectively compare FLAG to the newly FDA-approved CPX-351 in sAML.

Abstract
OBJECTIVE To evaluate the efficacy and safety of daunorubicin and cytarabine liposome in older adults with newly diagnosed therapy-related acute myeloid leukemia (t-AML) or AML with myelodysplasia-related changes (AML-MRC). DATA SOURCE A literature search of PubMed and MEDLINE (January 2017 to January 2018) was performed using the terms CPX-351, Vyxeos, daunorubicin and cytarabine liposome, and acute myeloid leukemia. STUDY SELECTION/DATA EXTRACTION Phase I, II, and III clinical trials evaluating the efficacy and safety of daunorubicin and cytarabine liposome were reviewed with a specific focus on its use in older patients with newly diagnosed AML. All peer-reviewed articles with clinically relevant information were evaluated for inclusion. DATA SYNTHESIS The phase II trial demonstrated that daunorubicin and cytarabine liposome improved response rates (RR), but there was no difference in event-free survival and overall survival in the overall patient population. However, clinical benefit was most pronounced in secondary AML with an increased RR and survival. The phase III trial illustrated that daunorubicin and cytarabine liposome improved survival and RR with tolerable toxicity compared with standard 7 plus 3 (daunorubicin and cytarabine) in patients 60 to 75 years of age with t-AML or AML-MRC. More patients proceeded to a stem cell transplant, and 30-day and 60-day mortality was lower with daunorubicin and cytarabine liposome. Grade 3 to 5 toxicities were similar between the 2 groups, except daunorubicin and cytarabine liposome had prolonged cytopenia and a higher risk of hemorrhage. CONCLUSIONS Daunorubicin and cytarabine liposome improves RR and survival, with tolerable toxicity in older patients with t-AML or AML-MRC.

Abstract
Multiple novel therapeutic agents against acute myeloid leukemia (AML) have been evaluated in the past several decades without meaningful clinical improvement in outcomes, especially for AML patients age ≥60, where the overall incidence of AML is highest. Therapeutic options mainly consist of hypomethylating agents, ongoing clinical trials and, less commonly, intensive cytotoxic chemotherapy. CPX-351, a novel liposomal formulation which encapsulates cytarabine and daunorubicin in 5:1 molar ratio, has shown promising efficacy, leading to recent US FDA approval for front-line therapy for patients with therapy-related AML and AML with myelodysplasia-related changes based on a large multicenter Phase III clinical trial. This review summarizes the clinical development of CPX-351 as induction therapy.

Abstract
PURPOSE CPX-351 is a novel liposomal formulation of cytarabine and daunorubicin which has recently been FDA approved for treatment of acute myeloid leukemia (AML). The current study investigated the pharmacokinetics (PK) of this liposomal formulation. METHODS CPX-351 PK data (cytarabine, daunorubicin, and metabolites) from a phase I study of relapsed and refractory AML were used for the analysis. Therapy was given days 1, 3, and 5 of induction (3-134 units/m2). We developed a population PK model to characterize CPX-351 disposition. RESULTS 39 patients (3589 samples) were evaluated. Liposomal cytarabine and daunorubicin were modeled separately with their respective metabolites. A one-compartment model fit the parent compounds well; the metabolites required two-compartment models. Weight was an independent predictor of liposomal volumes; mild renal and liver dysfunction were not predictors of clearance or volume (maximum creatinine 1.6 mg/dL and total bilirubin 1.8 mg/dL). Liposomal clearances of the two drugs were highly correlated and 1000-fold smaller than published non-encapsulated values supporting prolonged encapsulation in the liposome. CONCLUSIONS The PK model demonstrates prolonged exposure to cytarabine and daunorubicin without increases in non-hematologic toxicity that indicates retention of the drugs within the liposome. The unique pharmacology of this formulation may allow for simplified regimens and improved outcomes.

Abstract
Data have shown that intensified cytarabine in consolidation for treatment of acute myeloid leukemia (AML) does not equally benefit patients older than 60 years, and older patients experience significantly more neurotoxicity than younger patients. In addition, older patients are more likely to have abnormal or unfavorable cytogenetics, which also tend to confer limited efficacy with intensified cytarabine. This poses a treatment dilemma as to the best post remission therapy to treat older patients. This review explores some of the consolidation treatment strategies and options available for the older AML patient.
