Amrubicin for relapsed small-cell lung cancer: a systematic review and meta-analysis of 803 patients.
    Scientific reports, 2016, Jan-11, Volume: 6

    Currently, amrubicin is permitted for relapsed small-cell lung carcinoma (SCLC) only in Japan. The efficacy and adverse effects of amrubicin as reported by previous studies varied greatly. The inclusion criterion was a prospective study that was able to provide data for efficacy and safety by the AMR single agent regimen as second-line chemotherapy for a patient with SCLC. Binary data were meta-analyzed with the random-model generic inverse variance method. We included nine articles consisted of 803 patients. The pooled three-, six-, and nine-month progression-free survival were 63% (95% CI 57-69%, I(2) = 53%), 28% (95% CI 21-35%, I(2) = 71%), and 10% (95% CI 6-14%, I(2) = 41%), respectively. The pooled six-, 12-, and 18-month overall survival were 69% (95% CI 61-78%, I(2) = 83%), 36% (95% CI 28-44%, I(2) = 80%), and 15% (95% CI 8-21%, I(2) = 81%), respectively. Amrubicin seemed much more beneficial for Japanese patients. However, compared to the efficacy of topotecan presented in a previous meta-analysis, amrubicin may be a better treatment option than topotecan for both Japanese and Euro-American. Adverse effects by amrubicin were almost exclusively observed to be hematological. Notably, grade III/IV neutropenia incidence was 70% and febrile neutropenia incidence was 12%.

Phase II study of amrubicin at a dose of 45 mg/m2 in patients with previously treated small-cell lung cancer.
    Japanese journal of clinical oncology, 2015, Volume: 45, Issue:10

    Most of the previous studies of amrubicin in patients with previously treated small-cell lung cancer were conducted at a dose of 40 mg/m(2). The aim of this study was to assess the efficacy and safety of amrubicin at a dose of 45 mg/m(2) in patients with relapsed or refractory small-cell lung cancer.. Previously treated small-cell lung cancer patients were eligible. Amrubicin at a dose of 45 mg/m(2) was administered on Days 1-3 every 3 weeks. The primary endpoint was the response rate.. From June 2003 to January 2005, 35 patients were enrolled, of whom 34 received this study treatment. Four cycles or more could be administered in 21 patients (62%). Dose reduction was required in 15 (52%) of the 29 patients who had received two cycles or more. Three complete responses and 15 partial responses were observed among the 34 treated patients, yielding a response rate of 53% (95% confidence interval, 35-71%). Median progression-free survival of the patients was 4.4 months (95% confidence interval, 2.4-5.1 months). Median survival time was 8.2 months (95% confidence interval, 6.6-10.0 months) and 1-year survival rate was 24% (95% confidence interval, 9-39%). Grade 3/4 leukopenia, neutropenia and thrombocytopenia were observed in 76, 97 and 38% of the patients, respectively. Febrile neutropenia occurred in 12 patients (35%), and one patient died from pneumonia.. While amrubicin at a dose of 45 mg/m(2) showed high response rate for both sensitive and refractory relapse, the incidence of febrile neutropenia was also high. The utility of amrubicin at 45 mg/m(2) might accordingly be limited.

A phase I/II trial of irinotecan plus amrubicin supported with G-CSF for extended small-cell lung cancer.
    Japanese journal of clinical oncology, 2014, Volume: 44, Issue:2

    This study reports the findings of a Phase I/II, cohort, dose-escalation trial of amrubicin and irinotecan with the support of granulocyte colony-stimulation factor. This study aimed to determine the dose-limiting toxicity of the combination and to define the maximum-tolerated dose, as a recommended dose for Phase II trials. We also sought to obtain preliminary data on the efficacy of this combination as a frontline therapy for extensive-disease small-cell lung cancer.. We included 23 chemo-naïve patients with extensive-disease small-cell lung cancer in the trial. The amrubicin dose was escalated from 35 to 40 mg/m(2) (Levels 1 and 2, respectively) to determine the dose-limiting toxicity, with an unchanged dose of irinotecan at 50 mg/m(2).. Of nine patients, three experienced dose-limiting toxicities at Level 1 of prolonged Grade 4 neutropenia, Grade 3 febrile neutropenia and Grade 3 febrile neutropenia with Grade 3 diarrhea. At Level 2, two patients experienced dose-limiting toxicities of Grade 4 neutropenia and Grade 3 neutropenia with Grade 4 diarrhea. The maximum-tolerated doses and recommended doses for amrubicin and irinotecan were therefore determined to be 35 and 50 mg/m(2), respectively. The Level 1 trial was then expanded to 21 patients, 14 (70%) of whom showed partial responses to the recommended dose. The median progression-free and overall survival times were 6.37 and 15.21 months, respectively.. The combination of amrubicin and irinotecan with the support of granulocyte colony-stimulation factor produced a potent effect in chemo-naïve extensive-disease small-cell lung cancer patients. The use of biomarkers for this regimen may identify patients who are likely to suffer from treatment-ending severe adverse effects.

A phase II study of amrubicin and carboplatin for previously untreated patients with extensive-disease small cell lung cancer.
    Cancer chemotherapy and pharmacology, 2014, Volume: 74, Issue:3

    Amrubicin is active in the treatment of extensive-disease small cell lung cancer (ED-SCLC), and carboplatin is an analogue of cisplatin with less non-hematological toxicity.. The purpose of this study was to determine the efficacy and toxicity of amrubicin and carboplatin combination chemotherapy for previously untreated patients with ED-SCLC.. Eligibility criteria were chemotherapy-naïve ED-SCLC patients, performance status 0-1, age ≤75, and adequate hematological, hepatic and renal function. Based on the phase I study, the patients received amrubicin 35 mg/m(2) i.v. infusion on days 1, 2, and 3, and carboplatin AUC 5 i.v. infusion on day 1. Four cycles of chemotherapy were repeated every 3 weeks.. Thirty-five patients were enrolled, and 34 patients were eligible and assessable for response, toxicity, and survival. Patients' characteristics were as follows: male/female = 26/8; performance status 0/1 = 4/30; median age (range) = 64 (41-75); stage IV = 34. Evaluation of responses was 6 complete response, 21 partial response, and 7 stable disease (response rate 79.4 %, 95 % CI 63.6-88.5 %). Grade 3 and 4 leukopenia, neutropenia, and thrombocytopenia occurred in 59, 82, and 26 %, respectively. There were no treatment-related deaths or pneumonitis. Three patients experienced hypotension as an amrubicin infusion reaction. The median progression-free survival time was 6.5 months. The median overall survival time and 1-, 2-, and 3-year survival rates were 15.6 months, and 63, 28, and 7 %, respectively.. Amrubicin and carboplatin were effective and tolerable as chemotherapy for previously untreated patients with ED-SCLC. Further investigation of amrubicin and carboplatin is warranted.

Randomized phase II trial of single-agent amrubicin or topotecan as second-line treatment in patients with small-cell lung cancer sensitive to first-line platinum-based chemotherapy.
    Journal of clinical oncology : official journal of the American Society of Clinical Oncology, 2011, Jan-20, Volume: 29, Issue:3

    This phase II study evaluated the safety and efficacy of single-agent amrubicin versus topotecan in patients with small-cell lung cancer (SCLC) sensitive to first-line platinum-based chemotherapy.. Patients were randomly assigned 2:1 to amrubicin (40 mg/m(2)/d in a 5-minute intravenous [IV] infusion, days 1 through 3, every 21 days) or topotecan (1.5 mg/m(2)/d in a 30-minute IV infusion, days 1 through 5, every 21 days). The primary efficacy end point was overall response rate (ORR) for amrubicin. Secondary end points included time to progression, median progression-free survival (PFS), and median overall survival (OS).. Of 76 patients enrolled, 50 patients were randomly assigned to amrubicin, and 26 patients were randomly assigned to topotecan. Amrubicin treatment resulted in a significantly higher ORR than topotecan (44% v 15%; P = .021). Median PFS and median OS were 4.5 months and 9.2 months with amrubicin and 3.3 months and 7.6 months with topotecan, respectively. Tolerability was similar with both agents. However, grade 3 or worse neutropenia and thrombocytopenia seemed to be more frequent in the topotecan group as compared with the amrubicin group (78% and 61% v 61% and 39%, respectively).. Amrubicin shows promising activity, with an ORR of 44% compared with an ORR of 15% for topotecan as second-line treatment in patients with SCLC sensitive to first-line platinum-based chemotherapy. In addition, the safety profiles were comparable; however, a trend was noted for more frequent grade 3 or worse neutropenia and thrombocytopenia in the topotecan group as compared with the amrubicin group. Additional studies are ongoing.

Phase II trial of amrubicin and carboplatin in patients with sensitive or refractory relapsed small-cell lung cancer.
    Lung cancer (Amsterdam, Netherlands), 2011, Volume: 73, Issue:3

    Amrubicin is a novel, totally synthesized anthracycline derivative, and has antitumor activity against several human tumor xenografts. The combination of amrubicin with platinum derivative showed additive effect against a human small-cell lung cancer (SCLC) cell line. Until now, the combination of amrubicin plus carboplatin has not been studied in patients with previously treated SCLC. Therefore, we examined the safety and efficacy of the combination of amrubicin plus carboplatin in patients with sensitive or refractory relapsed SCLC. Patients with previously treated SCLC were eligible if they had a performance status of 2 or less, were 75 years or younger, and had adequate organ function. Twenty-five patients were enrolled (21 men and 4 women; median age, 65 years; age range 55-73 years). Patients received the combination of amrubicin (30 mg/m(2) on days 1-3) plus carboplatin (with a target area under the concentration-versus-time curve of 4 mg min/ml using the Calvert formula on day 1) every 3 weeks. The overall response rate was 36.0% (95% confidence interval [CI], 18.0-57.5%). Response rates differed significantly between patients with sensitive relapse (58.3%; 95% CI, 27.7-84.8%) and those with refractory relapse (15.4%; 95% CI, 1.9-15.4%; p=0.03). The median survival time (MST) from the start of this treatment was 7 months (range: 1-42 months); the MST of patients with sensitive relapse (10 months) was significantly longer than that of patients with refractory relapse (5 months: p=0.004). The median progression-free survival (PFS) time was 3 months (range: 1-14 months): the median PFS time of patients with sensitive relapse (5 months) was significantly longer than that of patients with refractory relapse (2 months; p=0.01). The most frequent grade 3-4 toxicity was myelosuppression, especially neutropenia, which developed in 88% of patients. Grade 3-4 thrombocytopenia developed in 44% of patients, and anemia developed in 56%. Nonhematologic toxicities were generally mild to moderately severe and temporary. None of the patients had cardiotoxicity. In conclusion, this therapy is effective and well tolerated for previously treated SCLC.

A phase II study of amrubicin and topotecan combination therapy in patients with relapsed or extensive-disease small-cell lung cancer: Okayama Lung Cancer Study Group Trial 0401.
    Lung cancer (Amsterdam, Netherlands), 2011, Volume: 74, Issue:1

    Chemotherapy is a mainstay in the treatment of extensive-disease small-cell lung cancer (ED-SCLC), although the survival benefit remains modest. We conducted a phase II trial of amrubicin (a topoisomerase II inhibitor) and topotecan (a topoisomerase I inhibitor) in chemotherapy-naïve and relapsed SCLC patients.. Amrubicin (35 mg/m(2)) and topotecan (0.75 mg/m(2)) were administered on days 3-5 and 1-5, respectively. The objective response rate (ORR) was set as the primary endpoint, which was assessed separately in chemotherapy-naïve and relapsed cases.. Fifty-nine patients were enrolled (chemotherapy-naïve 31, relapsed 28). The ORRs were 74% and 43% in the chemotherapy-naïve and relapsed cases, respectively. Survival data were also promising, with a median progression-free survival time and median survival time of 5.3 and 14.9 months and 4.7 and 10.2 months in the chemotherapy-naïve and relapsed cases, respectively. Even refractory-relapsed cases responded to the treatment favorably (27% ORR). The primary toxicity was myelosuppression with grades 3 or 4 neutropenia in 97% of the patients, which led to grades 3 or 4 febrile neutropenia in 41% of the patients and two toxic deaths.. This phase II study showed the favorable efficacy and moderate safety profiles of a topotecan and amrubicin two-drug combination especially in relapsed patients with ED-SCLC.

Plasma concentration of amrubicinol in plateau phase in patients treated for 3 days with amrubicin is correlated with hematological toxicities.
    Anti-cancer drugs, 2009, Volume: 20, Issue:6

    Amrubicinol (AMR-OH) is an active metabolite of amrubicin (AMR), a novel synthetic 9-aminoanthracycline derivative. The time-concentration profile of AMR-OH exhibits a continuous long plateau slope in the terminal phase. To determine the relationships between the steady-state plasma concentration of AMR-OH and treatment effects and toxicities associated with AMR therapy, we carried out a pharmacokinetic/pharmacodynamic study in patients treated with AMR alone or the combination of AMR+cisplatin (CDDP). AMR was given at a dose of 30 or 40 mg/m(2) on days 1-3. Plasma samples were collected 24 h after the third injection (day 4). Plasma concentrations of AMR-OH or total CDDP were determined by a high-performance liquid chromatography or an atomic absorption spectrometry. Percent change in neutrophil count (dANC) and the plasma concentration of AMR-OH were evaluated using a sigmoid E(max) model. A total of 35 patients were enrolled. Significant relationships were observed between AMR-OH on day 4 and the toxicity grades of leukopenia, neutropenia, and anemia (P=0.018, P=0.012, and P=0.025, respectively). Thrombocytopenia grade exhibited a tendency toward relationship with AMR-OH on day 4 (P=0.081). The plasma concentration of AMR-OH on day 4 was positively correlated with dANC in the group of all patients, as well as in patients treated with AMR alone and in patients coadministered with CDDP. In conclusion, the plasma concentration of AMR-OH on day 4 was correlated with hematological toxicities in patients treated with AMR. The assessment of plasma concentration of AMR-OH at one timepoint might enable the prediction of hematological toxicities.

Phase I and pharmacokinetic study of amrubicin, a synthetic 9-aminoanthracycline, in patients with refractory or relapsed lung cancer.
    Cancer chemotherapy and pharmacology, 2006, Volume: 57, Issue:3

    Amrubicin is a novel synthetic 9-aminoanthracycline derivative and is converted enzymatically to its C-13 hydroxy metabolite, amrubicinol, whose cytotoxic activity is 10-100 times that of amrubicin. We aimed to determine the maximum tolerated dose (MTD) of amrubicin and to characterize the pharmacokinetics of amrubicin and amrubicinol in previously treated patients with refractory or relapsed lung cancer. The 15 patients were treated with amrubicin intravenously at doses of 30, 35, or 40 mg/m(2) on three consecutive days every 3 weeks for a total of 43 courses. Neutropenia was the major toxicity (grade 4, 67%). The MTD was 40 mg/m(2), with the specific dose-limiting toxicities being grade 4 neutropenia persisting for >4 days, febrile neutropenia, or grade 3 arrhythmia in the three patients treated at this dose. A patient with non-small-cell lung cancer showed a partial response, and ten individuals experienced a stable disease. The area under the plasma concentration versus time curve (AUC) for amrubicin and that for amrubicinol increased with amrubicin dose. The amrubicin AUC was significantly correlated with the amrubicinol AUC. The recommended phase II dose of amrubicin for patients with lung cancer refractory to standard chemotherapy is thus 35 mg/m(2) once a day for three consecutive days every 3 weeks.

Phase I study of amrubicin hydrochloride and cisplatin in patients previously treated for advanced non-small cell lung cancer.
    Japanese journal of clinical oncology, 2006, Volume: 36, Issue:1

    A single-center phase I trial was designed to determine both the dose-limiting toxicities and the maximum tolerated dose (MTD) for amrubicin hydrochloride in combination therapy with cisplatin for advanced non-small cell lung cancer (NSCLC) patients with prior chemotherapy.. Eligible patients received amrubicin and cisplatin on days 1 through 3 every 3 or 4 weeks. Cisplatin was administered at a fixed dosage of 20 mg/m(2) while the administered dose of amrubicin was started at 20 mg/m(2). Each group comprised 3 or 6 patients. When dose limiting toxicities were noted in three or more of six patients at a particular level, that level was estimated to be the MTD.. Fifteen patients were enrolled in this study, including 5 males and 10 females, with a median age of 57. The dose limiting toxicities included grade 4 neutropenia which lasted 4 or more days and febrile neutropenia. The non-hematologic toxicities were well managed and rarely severe. The MTD of amrubicin in this combination regimen was estimated to be 30 mg/m(2).A partial response was observed in 4 of 15 patients (27%).. The recommended dose was thus determined to be 25 mg/m(2) amrubicin with 20 mg/m(2) cisplatin for 3 consecutive days. A phase II study is currently underway.

Phase I/II study of amrubicin, a novel 9-aminoanthracycline, in patients with advanced non-small-cell lung cancer.
    Investigational new drugs, 2005, Volume: 23, Issue:4

    Amrubicin is a novel, totally synthetic 9-aminoanthracycline. The present phase I/II study was performed to define its maximum-tolerated dose (MTD), efficacy and toxicity in the treatment of previously untreated patients with advanced non-small-cell lung cancer (NSCLC).. Chemonaive patients were required to have cytologically or histologically proven measurable NSCLC, an Eastern Cooperative Oncology Group (ECOG) performance status (PS) of 0 to 2, and adequate organ functions. Amrubicin was administered by daily intravenous injection for 3 consecutive days every 3 weeks.. In a phase I study, four patients were enrolled at dose level 1 (40 mg/m(2)/day) and four at dose level 2 (45 mg/m(2)/day). No dose limiting toxicity (DLT), which was defined as toxicity consisting of grade 4 neutropenia and leukopenia lasting four days or more, and grade 3 or 4 toxicity other than neutropenia, leukopenia, anorexia, nausea/vomiting, and alopecia, was observed at these dose levels. Subsequently, at dose level 3 (50 mg/m(2)/day), 3 of 5 patients experienced DLTs (leukopenia, neutropenia, thrombocytopenia, or gastrointestinal complications). The MTD and recommended dose (RD) were determined to be 50 mg/m(2)/day and 45 mg/m(2)/day, respectively. Three partial responses (PRs) were achieved in 13 patients (response rate, 23.1%) in a phase I study. In a phase II study, 15 patients were assessable for efficacy and toxicity at the RD, and four PRs were obtained (response rate, 26.7%). The major toxicities were leukopenia and neutropenia, while non-hematologic toxicities were mild. The overall response rate in the combined patient population of the phase I/II study was 25.0% (7 PRs in 28 patients), with a 95% confidence interval of 10.7% to 44.9%.. Amrubicin exerted promising antitumor activity on NSCLC with acceptable toxicity.

Efficacy of Platinum-Based Chemotherapy for Relapsed Small-Cell Lung Cancer after Amrubicin Monotherapy in Elderly Patients and Patients with Poor Performance Status.
    Oncology, 2018, Volume: 94, Issue:4

    Previous studies have shown amrubicin to be an effective first- or second-line treatment option for small-cell lung cancer (SCLC). However, there have been few studies reporting the efficacy of platinum-based chemotherapy after amrubicin therapy. We aimed to evaluate the efficacy of platinum-based chemotherapy as second-line treatment for elderly patients and those with SCLC with poor performance status (PS) previously treated with amrubicin monotherapy.. The records of SCLC patients who received platinum-based chemotherapy as a second-line chemotherapy after first-line treatment with amrubicin monotherapy were retrospectively reviewed and the treatment outcomes were evaluated.. A total of 48 patients were enrolled in this study. Forty-one patients (85%) received carboplatin plus etoposide. The overall response rate was 39.6%. The median progression-free survival and overall survival were 3.7 and 7.6 months, respectively. The efficacy of the platinum-based regimen did not differ with the type of relapse after amrubicin monotherapy. The most common adverse events were hematological toxicities, including grade 3 or 4 neutropenia (38%), leukopenia (33%), and thrombocytopenia (10%).. Platinum-based chemotherapy is potentially a valid treatment option for elderly patients or those with extensive-stage SCLC with poor PS as second-line chemotherapy, who progressed after first-line treatment with amrubicin monotherapy.

Amrubicin Monotherapy for Patients with Platinum-Pretreated Non-Gastrointestinal Non-Pancreatic Extrapulmonary Neuroendocrine Carcinoma.
    Oncology, 2017, Volume: 93, Issue:3

    The aim of this study was to investigate the clinical usefulness of amrubicin therapy for patients with non-gastrointestinal (GI) non-pancreatic extrapulmonary neuroendocrine carcinoma (EP-NEC).. The medical records of patients from the 2 participating institutions were retrospectively reviewed. The eligibility criteria were: patients with non-GI non-pancreatic EP-NEC who received amrubicin monotherapy after platinum-based chemotherapy. Patients in whom the platinum-free interval (interval between the last day of platinum administration and the first subsequent documentation of disease progression) was 90 days or longer were classified into the platinum-sensitive group.. The study was conducted in a total of 13 patients identified as eligible. The response rate was 45.4% (5/11). The median progression-free survival and overall survival were 6.0 and 10.6 months, respectively. A platinum-free interval of ≥90 days was identified as a significant predictor of a longer progression-free survival time. Grade 3 or 4 neutropenia was observed in 61.5% (8/13) of the patients. One patient died of treatment-related febrile neutropenia.. Amrubicin monotherapy as second-line chemotherapy after failure of first-line platinum-based chemotherapy showed good efficacy in patients with non-GI non-pancreatic EP-NEC. Neutropenia was encountered as the most serious adverse event.

ABCB1 polymorphism as a predictive biomarker for amrubicin-induced neutropenia.
    Anticancer research, 2014, Volume: 34, Issue:7

    Amrubicin is a promising therapy for lung cancer, but is associated with a high incidence of severe neutropenia. The present study assessed the utility of ABCB1 and NAD(P)H quinone oxidoreductase 1 (NQO1) polymorphism as a predictor of amrubicin-induced neutropenia.. Fifty-four Japanese lung cancer patients who received amrubicin chemotherapy were consecutively recruited and toxicities and SNPs (MDR1; C1236T, C3435T and G2677T/A, NQO1; C609T) were evaluated.. The incidence of neutropenia was higher in patients treated with 40 mg/m2 of amrubicin (n=32) compared to patients treated with 35 mg/m2 of amrubicin (n=22) (53.1% vs. 22.7%). Patients who were homogenous for the wild-type allele of C3435T were at significantly higher risk of neutropenia compared to patients with other genotypes. By contrast, the C609T genotype of NQO1 was not related to neutropenia.. C3435T polymorphisms of ABCB1 might be able to predict severe amrubicin-induced neutropenia.

Gender difference in hematological toxicity among lung cancer patients receiving amrubicin monotherapy.
    Japanese journal of clinical oncology, 2012, Volume: 42, Issue:12

    Severe hematological toxicity has been frequently observed during amrubicin monotherapy for patients with lung cancer despite the favorable anti-tumor response. The purpose of this retrospective study was to identify pretreatment factors associated with severe hematological toxicity.. The medical records of lung cancer patients treated with amrubicin monotherapy were reviewed, and univariate and multivariate analyses were conducted.. From January 2003 to December 2006, the medical records of 103 patients were extracted. Grade 4 neutropenia was frequently observed in females (male, 66% and female, 90%, P = 0.036 in a univariate analysis). In a multivariate analysis, female gender (P = 0.019), body weight loss (P = 0.021) and amrubicin dose (P = 0.028) were significantly correlated with Grade 4 neutropenia.. Gender could be considered as one of the important predictive factors associated with Grade 4 neutropenia in patients receiving amrubicin monotherapy.

Risk factors for predicting severe neutropenia induced by amrubicin in patients with advanced lung cancer.
    Chemotherapy, 2012, Volume: 58, Issue:6

    Neutropenia is one of the most frequent and dose-limiting toxicities in amrubicin (AMR) therapy. However, the predictive factors for the development of severe neutropenia in AMR therapy remain unknown.. The subjects were 61 advanced lung cancer patients treated with AMR monotherapy. All data were retrospectively collected from the electronic medical record system. A stepwise logistic regression analysis was performed to identify risk factors for grade 3-4 neutropenia.. Of a total 61 patients, 50 were male and 11 were female. The median dose of AMR was 35.0 mg/m(2). The incidence of grade 3-4 neutropenia during the first course was 62%. In multivariate analysis, female gender (OR = 6.68; 95% CI 1.01-134.15; p = 0.049), higher AMR doses (40 mg/m(2) or more) (OR = 5.98; 95% CI 1.77-23.74; p = 0.003), and lower hematocrit values (OR = 2.04 per 5% decrease; 95% CI 1.04-4.38; p = 0.036) were significantly associated with severe neutropenia induced by AMR.. The present results suggest that female gender, higher doses of AMR, and lower baseline hematocrit values are predictive factors associated with severe neutropenia induced by AMR in patients with advanced lung cancer. Patients who have these predictive factors should be monitored carefully and considered for early granulocyte colony-stimulating factor support.

Amrubicin at a lower-dose with routine prophylactic use of granulocyte-colony stimulating factor for relapsed small-cell lung cancer.
    Lung cancer (Amsterdam, Netherlands), 2011, Volume: 72, Issue:2

    Recent reports have suggested the efficacy of amrubicin (AMR) for relapsed small-cell lung cancer (SCLC). However, doses of AMR in these reports were 40 mg/m(2) or 45 mg/m(2), and severe and frequent myelosuppression were observed. Such side effects are occasionally intolerable, as serious myelosuppression may induce fatal infections. To overcome this clinical problem, we investigated whether 35 mg/m(2) of AMR administration with routine prophylactic use of granulocyte-colony stimulating factor (G-CSF) can reduce myelosuppression, while maintaining efficacy.. Between July 2003 and November 2008, 30 relapsed SCLC patients receiving 35 mg/m(2)/day of AMR were evaluated. Amrubicin was administered on days 1-3 every 3 or 4 weeks. Routine prophylactic use of G-CSF was performed beginning on day 8 and continuing for at least 5 consecutive days or until neutrophils recovered to the normal level.. The median number of treatment cycles was four (range 1-9). No complete responses and 13 partial responses were observed, with response rates of: overall 43% (95% confidence interval [CI]: 26-63%); sensitive cases 33% (95% CI: 10-65%); and refractory cases 50% (95% CI: 26-74%) (p=0.4651). The disease control rate (partial response and stable disease) was 80% (95% CI: 61-92%). The progression-free survival times were: overall 4.2 months (95% CI: 3.2-5.2 months); sensitive cases 4.7 months (95% CI: 2.6-5.4 months); and refractory cases 3.5 months (95% CI: 2.6-5.2 months) (p=0.7124). The median OS times were: overall 9.6 months (95% CI: 7.2-12.5 months); sensitive cases 8.4 months (95% CI: 4.6-13.4 months); and refractory cases 11.0 months (95% CI: 6.5-12.6 months) (p=0.9315). The 1-year survival rate was 33%. Regarding grade 3/4 hematological toxicities: leukopenia (47%); neutropenia (50%); anemia (30%); and thrombocytopenia (33%) were observed. Febrile neutropenia occurred in three patients (10%). Transfusions of red blood cells and platelets were performed for eight (27%) and one (3%) patients, respectively. Treatment-related deaths and grade 3/4 non-hematological toxicities were not observed at all.. Considering both safety and efficacy, AMR at a dose of 35 mg/m(2) with routine prophylactic use of G-CSF may be more desirable for the treatment of relapsed SCLC in clinical practice.

[Two cases of severe myelosuppression from amrubicin in previously-treated small cell lung cancer].
    Gan to kagaku ryoho. Cancer & chemotherapy, 2008, Volume: 35, Issue:3

    The patients were a 59-year-old man and 68-year-old man with previously-treated small cell lung cancer (extensive disease). Amrubicin (40 mg/m(2) and 45 mg/m(2)) was administered for 3 days after brain irradiation. Severe neutropenia continued for nine days from day 8 following administration. Although both patients had an infection, it improved by granulocyte-colony stimulating factor (G-CSF), and antibiotics, plus a blood transfusion. Particular attention for severe myelosuppression should be given to amrubicin therapy with previously-treated small cell lung cancer. However, a detailed blood test in course 1 and early administration of drugs such as G-CSF make this therapy feasible. In addition, to control the condition of patients, repeated administration of amrubicin with dose reduction is recommended.

[Analysis of adverse events of amrubicin hydrochloride for pretreated lung cancer patients].
    Gan to kagaku ryoho. Cancer & chemotherapy, 2007, Volume: 34, Issue:11

    Although amrubicin hydrochloride (AMR) has promising activity against pretreated lung cancer, there are few reports on the adverse events of this agent in a clinical practice setting. We analyzed the adverse events experienced in 27 hospitalized patients who had received AMR monotherapy by collecting data from the pharmaceutical management records. Neutropenia was the main hematological toxicity, and 77.8% of patients developed grade 3/4 neutropenia. Neutrophil counts reached the nadir in 9 to 21 (median 14) days and recovered to normal in 14 to 27 (median 20) days. Seven cases experienced febrile neutropenia without any serious sequelae. Grade 2 or worse non-hematological toxicities were fatigue, constipation, nausea, vomiting, anorexia, and pneumonitis. In comparison with the data of pre-marketing clinical trials, constipation was more commonly observed, while nausea/vomiting was less frequent probably due to appropriate preventive antiemetics. Based on these findings, we have created a novel drug information chart for patients and utilized it in pharmaceutical care in our hospital.

[A case of multiple pyomyositis after chemotherapy for lung cancer].
    Gan to kagaku ryoho. Cancer & chemotherapy, 2006, Volume: 33, Issue:6

    We here describe a case of multiple pyomyositis in a 62-year-old man who had systemic chemotherapy for recurrent lung cancer. His initial symptoms consisted of fever and general fatigue, followed by progressive pain and swelling in his extremities, which mimicked deep venous thrombosis along with bacterial infection. He was admitted to the hospital for intravenous administration of antibiotics. MRI appeared very useful to find the intramuscular fluid collections with circumferential inflammatory changes, which confirmed diagnosis of the multiple pyomyositis. Surgical drainage as well as intravenous administration of antibiotics worked very well and improved clinical symptoms in a few weeks after the treatments. He could resume normal activities with minimum functional impairments in the extremities. Pyomyositis should be kept in mind as one of the adverse effects after chemotherapy for malignant tumors.

[Profile of the anti-tumor effects of amrubicin, a completely synthetic anthracycline].
    Nihon yakurigaku zasshi. Folia pharmacologica Japonica, 2003, Volume: 122, Issue:2

    Amrubicin is a completely synthetic anthracycline derivative. In contrast, however, the anthracyclines used clinically thus far have been produced by fermentation or semisynthesis. Amrubicin is structurally distinguishable from other anthracyclines by the amino group at the 9-position and its unique sugar moiety. Amrubicinol, the C-13 hydroxy- metabolite of amrubicin, is associated with a 5 to 200 times greater cytotoxicity than amrubicin. Amrubicin exhibited superior in vivo antitumor activity to doxorubicin in the human tumor xenograft model. Using this model, the level of amrubicinol (active metabolite) was shown to be higher than that of doxorubicin in tumor tissues, but lower in normal tissues. These results suggest potent therapeutic activity for amrubicin because of the selective distribution of its highly active metabolite, amrubicinol, in tumors. These anti-tumor effects of amrubicin are considered to be induced by DNA topoisomeraseII inhibition. In clinical studies, amrubicin has demonstrated potent single agent activity as compared to a standard regimen in untreated patients with extensive small cell lung cancer. Its major toxicity was myelosuppression (especially neutropenia).
