Abstract
OBJECTIVES There are limited treatment options for patients with thymic malignancies. Here we present data supporting treatment with single agent amrubicin, a third generation anthracycline and topoisomerase II inhibitor. MATERIALS AND METHODS This was a phase 2 open-label, single arm trial of amrubicin in patients with thymoma (T) or thymic carcinoma (TC), conducted at two academic institutions. Patients were included if they had received at least one prior chemotherapy regimen. The first 18 patients received amrubicin at 40 mg/m2 IV days 1-3 repeated every 3-weeks. Due to the high incidence of febrile neutropenia, dosing was subsequently amended to 35 mg/m2 for the final 15 patients. RESULTS A total of 33 patients (14 T/19 TC) were enrolled from 2011 to 2014. Median number of prior therapies was 2. Best response included 6 partial responses, 21 stable disease, and 6 progressive disease (all TC). Objective response rate was 18% (90% exact binomial CI 8.2%-32.8%; T = 4/14 (29%), TC = 2/19 (11%)). Median progression-free survival was 7.7 months (T: 8.3 months; TC: 7.3) and median overall survival was 29.7 months (T: 54.1 months; TC: 18 months). There was a high rate of febrile neutropenia (7 patients) that occurred despite a reduction in amrubicin dose and one related death. Five patients had reduction in LVEF below 50% during the course of treatment resulting in treatment discontinuation in one patient. CONCLUSION Amrubicin shows promise as a single agent in heavily pre-treated patients with thymic malignancies. Notable side effects include febrile neutropenia and the use of growth factor support is essential. Further investigation of this agent is warranted.

Abstract
The antitumor anthracycline, doxorubicin (DOX), can cause heart failure (HF) upon cumulative administration. Lowering the cumulative dose of DOX proved useful to minimize HF risk, and, yet, there is a growing concern that HF might occur after doses that were thought to be safe. Clinical trials that prospectively address such concerns are lacking. Because HF risk correlates with cardiac exposure to DOX, cumulative doses associated with HF risk were re-explored by modeling the accumulation of anthracycline pools in human myocardium. Ex vivo myocardial samples were used in vitro to simulate DOX rapid infusions. The accumulation of anthracycline pools was measured and incorporated into equations from which a risk versus dose curve was obtained. The experimental curve identified a 5% risk dose that was congruent with a previously reported clinical value (380 versus 400 mg/m2, respectively); however, 1-2% risk occurred after lower doses than reported. Simulations of gain-of-function polymorphism of carbonyl reductase 3, which converts DOX to its poorly diffusible alcohol metabolite, doxorubicinol (DOXOL), expanded anthracycline pools and caused 5% or 1-2% risk doses to decrease to 330 or 180-230 mg DOX/m2, respectively. These data show there is no safe dose of DOX. Diminishing cardiac exposure to circulating DOX may represent a cardioprotective strategy. We show that DOX slow infusions or liposomal DOX, which reduce cardiac exposure to DOX, caused formation of smaller anthracycline pools, did not generate DOXOL, increased the 5% risk dose to 750-800 mg/m2, and prevented HF risk aggravation by carbonyl reductase polymorphism.

Abstract
Antitumor drugs have long been known to introduce a measurable risk of cardiovascular events. Cardio-Oncology is the discipline that builds on collaboration between cardiologists and oncologists and aims at screening, preventing or minimizing such a risk. Overt concern about "possible" cardiovascular toxicity might expose cancer patients to the risk of tumor undertreatment and poor oncologic outcome. Careful analysis of risk:benefit balance is therefore central to the management of patients exposed to potentially cardiotoxic drugs. Concomitant or sequential management of cardiac and cancer therapies should also be tailored to the following strengths and weaknesses: i) molecular mechanisms and clinical correlates of cardiotoxicity have been characterized to some extent for anthracyclines but not for other chemotherapeutics or new generation "targeted" drugs, ii) anthracyclines and targeted drugs cause different mechanisms of cardiotoxicity (type I versus type II), and this classification should guide strategies of primary or secondary prevention, iii) with anthracyclines and nonanthracycline chemotherapeutics, cardiovascular events may occur on treatment as well as years or decades after completing chemotherapy, iv) some patients may be predisposed to a higher risk of cardiac events but there is a lack of prospective studies that characterized optimal genetic tests and pharmacologic measures to minimize excess risk, v) clinical toxicity may be preceded by asymptomatic systolic and/or diastolic dysfunction that necessitates innovative mechanism-based pharmacologic treatment, and vi) patient-tailored pharmacologic correction of comorbidities is important for both primary and secondary prevention. Active collaboration of physicians with laboratory scientists is much needed for improving management of cardiovascular sequelae of antitumor therapy. This article is part of a Special Issue entitled: Membrane channels and transporters in cancers.

Abstract
Amrubicin is a synthetic anthracycline which has been shown in preclinical studies to have broad-spectrum anti-tumor activity and a lower potential for cardiotoxicity as compared to doxorubicin. We conducted a phase 1/2 trial of single-agent amrubicin as second- or third-line treatment for women with metastatic breast cancer. Women with metastatic HER2-negative breast cancer who had normal cardiac function and measurable disease, received intravenous (IV) amrubicin every 3 weeks. Prophylactic treatment with granulocyte colony-stimulating factors (G-CSFs) was recommended. Escalating amrubicin doses were administered in a 3 + 3 design in the phase 1 portion to determine the maximum tolerated dose. Achievement of a median PFS ≥4.5 months would warrant further development of amrubicin in this setting. Seventy-eight women (median age 58 years) were treated (phase 1, 15 patients; phase 2, 63 patients). An amrubicin dose of 110 mg/m(2) every 3 weeks was selected as the phase 2 dose, and 66 patients were treated. Twelve of 66 patients (18%) achieved objective response, and the clinical benefit rate was 42%. Median PFS was 4 months (95% CI 2.5, 5.8). Neutropenia was the most common grade 3/4 toxicity, observed in 29 patients (44%). One patient experienced an asymptomatic transient left ventricular ejection fraction decline (grade 3). Although the study did not meet the predefined PFS, amrubicin was well tolerated at 110 mg/m(2) IV when administered every 3 weeks with prophylactic G-CSF, and was an active second- or third-line treatment for metastatic HER2-negative breast cancer.

Abstract
Leukemias are one of most common malignancies worldwide. There is a substantial need for new chemotherapeutic drugs effective against this cancer. Doxorubicin (DOX), used for treatment of leukemias and solid tumors, is poorly efficacious when it is administered systemically at conventional doses. Therefore, several strategies have been developed to reduce the side effects of this anthracycline treatment. In this study we compared the effect of DOX and doxorubicin-transferrin conjugate (DOX-TRF) on human leukemia cell lines: chronic erythromyeloblastoid leukemia (K562), sensitive and resistant (K562/DOX) to doxorubicin, and acute lymphoblastic leukemia (CCRF-CEM). Experiments were also carried out on normal cells, peripheral blood mononuclear cells (PBMC). We analyzed the chemical structure of DOX-TRF conjugate by using mass spectroscopy. The in vitro growth-inhibition assay XTT, indicated that DOX-TRF is more cytotoxic for leukemia cells sensitive and resistant to doxorubicin and significantly less sensitive to normal cells compared to DOX alone. During the assessment of intracellular DOX-TRF accumulation it was confirmed that the tested malignant cells were able to retain the examined conjugate for longer periods of time than normal lymphocytes. Comparison of kinetic parameters showed that the rate of DOX-TRF efflux was also slower in the tested cells than free DOX. The results presented here should contribute to the understanding of the differences in antitumor activities of the DOX-TRF conjugate and free drug.

Abstract
Small-cell lung cancer (SCLC) is the most aggressive form of lung cancer characterized by early metastasis and high mortality. In recent years, monotherapy and combination therapy of amrubicin with cisplatin or carboplatin has been actively studied and shown promise for the treatment of extensive disease SCLC (ED-SCLC). In this article, we summarize clinical trials of both monotherapy and combination therapy with amrubicin conducted in Japan, the USA, and the European Union. The results suggest that the clinical outcome of amrubicin therapy may be associated with genetic variations in patients. Further study of combination regimens in patients of different ethnicities is warranted.

Abstract
Anthracycline-related cardiotoxicity correlates with cardiac anthracycline accumulation and bioactivation to secondary alcohol metabolites or reactive oxygen species (ROS), such as superoxide anion (O₂·⁻) and hydrogen peroxide H₂O₂). We reported that in an ex vivo human myocardial strip model, 3 or 10 μM amrubicin [(7S,9S)-9-acetyl-9-amino-7-[(2-deoxy-β-D-erythro-pentopyranosyl)oxy]-7,8,9,10-tetrahydro-6,11-dihydroxy-5,12-napthacenedione hydrochloride] accumulated to a lower level compared with equimolar doxorubicin or epirubicin (J Pharmacol Exp Ther 341:464-473, 2012). We have characterized how amrubicin converted to ROS or secondary alcohol metabolite in comparison with doxorubicin (that formed both toxic species) or epirubicin (that lacked ROS formation and showed an impaired conversion to alcohol metabolite). Amrubicin and doxorubicin partitioned to mitochondria and caused similar elevations of H₂O₂, but the mechanisms of H₂O₂ formation were different. Amrubicin produced H₂O₂ by enzymatic reduction-oxidation of its quinone moiety, whereas doxorubicin acted by inducing mitochondrial uncoupling. Moreover, mitochondrial aconitase assays showed that 3 μM amrubicin caused an O₂·⁻-dependent reversible inactivation, whereas doxorubicin always caused an irreversible inactivation. Low concentrations of amrubicin therefore proved similar to epirubicin in sparing mitochondrial aconitase from irreversible inactivation. The soluble fraction of human myocardial strips converted doxorubicin and epirubicin to secondary alcohol metabolites that irreversibly inactivated cytoplasmic aconitase; in contrast, strips exposed to amrubicin failed to generate its secondary alcohol metabolite, amrubicinol, and only occasionally exhibited an irreversible inactivation of cytoplasmic aconitase. This was caused by competing pathways that favored formation and complete or near-to-complete elimination of 9-deaminoamrubicinol. These results characterize amrubicin metabolic advantages over doxorubicin and epirubicin, which may correlate with amrubicin cardiac safety in preclinical or clinical settings.
