Abstract

Purpose: Amrubicin is a novel 9-aminoanthracycline. This multicenter phase II study was conducted to evaluate the efficacy and safety of amrubicin in patients with non-small-cell lung cancer (NSCLC). Patients and methods: Sixty-one previously untreated patients with stage III or IV NSCLC were entered this study. The patients were required to have cytologically or histologically proven measurable NSCLC, an Eastern Cooperative Oncology Group (ECOG) performance status of 0-2, and adequate organ function. Amrubicin was administered by daily intravenous injection at 45 mg/m2/day for 3 consecutive days every 3 weeks. At least 3 cycles of treatment were administered to each patient. Results: All 61 patients registered in this trial were eligible and assessable for efficacy and toxicity. Of them, 17 patients achieved objective responses, consisting of one complete response and 16 partial responses, and the overall response rate was 27.9% (95% confidence interval [CI], 17.1% to 40.8%). The median survival time was 9.8 months (95% CI, 7.7 months to 14.9 months). The major toxicity was myelosuppression. The incidences of grade 3 or 4 toxicity were 72.1% for neutropenia, 52.5% for leukopenia, 23.0% for anemia, and 14.8% for thrombocytopenia. As noticeable toxic events, grade 3 hypotention and alkaline phosphatase elevation were transiently observed in one patient each. In addition, three patients who had had asymptomatic interstitial pneumonitis, identified by diagnostic imaging before treatment, aggravated after amrubicin treatment; two of them died. Other non-hematologic toxicities were relatively mild. Conclusion: Amrubicin was an active, well-tolerated agent in the treatment of NSCLC.
