[Late phase II clinical study of amrubicin hydrochloride, a novel synthetic anthracycline derivative anticancer agent, for malignant lymphoma].
A late phase II clinical trial of amrubicin hydrochloride, a novel synthetic anthracycline derivative anticancer agent, was conducted at 14 institutions nationwide, in patients with non-Hodgkin's lymphoma. In this multi-center collaborative study, doxorubicin hydrochloride was replaced by amrubicin hydrochloride in CHOP therapy, a standard regimen for non-Hodgkin's lymphoma consisting of cyclophosphamide, doxorubicin hydrochloride, vincristine sulfate and prednisolone. A total of 39 patients were enrolled in this study between January 1996 and March 1998. Among them, 37 patients were eligible for this study. The study drugs were administered to patients with non-Hodgkin's lymphoma according to the following schedule: amrubicin hydrochloride (100 mg/m2, body surface area), cyclophosphamide (750 mg/m2) and vincristine sulfate (1.4 mg/m2, a maximal dose of 2.0 mg/body) were administered intravenously on day one, while prednisolone (60 mg/m2/day) was administered orally on days 1 to 5. This cycle of treatment was repeated every three weeks in principle. The efficacy and safety were assessed for 37 eligible patients. The combined rate for CR + CRu was 70.3% (26/37) and the overall response rate (CR + CRu + PR) was 86.5% (32/37). demonstrating that amrubicin hydrochloride was very effective in the treatment of non-Hodgkin's lymphoma. The most frequent adverse reactions that occurred during the study were myelosuppressions: leukopenia and neutropenia, 100% (37/37); and decreases in hemoglobin levels, 81.1% (30/37). Thrombocytopenia, elevations of serum GOT and GPT levels, anorexia, nausea/vomitting, fever, stomatitis and alopecia were also observed. Although leukopenia and neutropenia of grade 3 or higher were noted in 89.2% (33/37) and 94.6% (35/37), respectively, they were controllable by administrations of G-CSF or solely by follow-up observations. One patient developed intestinal paralysis (grade 4) and another developed hematemesis. In conclusion, these results indicate that amrubicin hydrochloride is an effective agent as a component of combination chemotherapy for non-Hodgkin's lymphoma.
