The pharmacokinetics and pharmacodynamics of mitoxantrone were studied in 15 patients with advanced nasopharyngeal carcinoma (NPC) after single intravenous rapid infusion (12 to 14 mg/m2). Mitoxantrone plasma concentrations and urinary excretion were measured specifically with the use of a high-performance liquid chromatographic method with ultraviolet detection at 242 and 658 nm. The pharmacokinetic parameters are described adequately by a three-compartment model with a terminal half-life of 71.5 +/- 40.1 hours and a volume of distribution of 5037 +/- 2377 l. The total plasma clearance was 743 +/- 462 ml/minute, and the renal clearance was 18.8 +/- 8.49 ml/minute. Within 72 hours, 1.8 +/- 0.6% of the administration dose was excreted in urine as mitoxantrone parent compound. From the urinary excretion rate data, glomerular filtration and possible tubular reabsorption were the mechanisms involved in the urinary excretion of mitoxantrone. The values for unbound fraction (%) in plasma at time 0 and 5 minutes were 2.88 +/- 0.91% and 3.25 +/- 1.19%, with an average of 3.04 +/- 1.01%. The degree of protein binding of mitoxantrone was not affected by concentration (P greater than 0.05) in Chinese patients with NPC. The response rate for mitoxantrone was poor in this study. Clinical studies have demonstrated that mitoxantrone was generally well tolerated. Only very low incidences of nausea, vomiting, and alopecia were observed. The mild and rapidly reversible dose-limiting hematologic toxic effects have proven leukopenia. Although the toxicities reported here were tolerated for most patients, other combination regimens including mitoxantrone or other administration routes may be considered and need to be evaluated carefully.

In this phase II multicenter trial, the efficacy and safety of mitoxantrone (Novantrone; Lederle Laboratories, Wayne, NJ) were evaluated in the treatment of 206 patients with relapsed non-Hodgkin's lymphoma (NHL) or Hodgkin's disease (HD) previously treated with other agents. Sixty-nine percent of the patients had received prior therapy with doxorubicin. The patients received 14 mg/m2 of mitoxantrone every 3 weeks. Nineteen (12%) of the NHL patients and two (7%) of the HD patients had complete responses (CRs). The combined CR and partial response (PR) rates were 37% (60 of 163) for NHL patients and 36% (10 of 28) for HD patients; the median duration of response was 323 days for NHL patients and 209 days for HD patients. The median survival times were 337 days for patients with NHL and 469 days for patients with HD. The median survival time for patients with low-grade NHL was 589 days compared with 298 days for patients with intermediate-grade NHL and 167 days for patients with high-grade NHL. The median time to treatment failure was 73 days for NHL patients and 98 days for HD patients. The major toxicity was myelosuppression, which was moderate and reversible. Nausea, vomiting, and alopecia were mild. There were two cases of congestive heart failure (CHF) considered related to treatment; both patients had received prior treatment with doxorubicin. In this group of heavily pretreated patients, mitoxantrone was effective and well tolerated. Responses were seen with mitoxantrone in patients who had relapsed after prior therapy with doxorubicin and in patients who had failed to respond to prior therapy with doxorubicin. Mitoxantrone should be evaluated in less heavily pretreated patients and should be considered for incorporation into combination chemotherapeutic regimens for the treatment of malignant lymphoma.

Mitoxantrone, an anthracenedione, has been shown to be as effective as doxorubicin, but with less local or systemic toxicity, when used for the treatment of advanced breast cancer. As the high molecular weight and hydrophilic property of this drug let us predict a slow intracavity resorption, we tested its use in the treatment of malignant effusions refractory to systemic chemotherapy. 18 women, 43 to 83 years old, with cytologically demonstrated metastatic pleural effusions, and with prominent clinical symptoms, were included in the study. All these patients were refractory to hormonotherapy and combination chemotherapy (previous regimens included anthracyclines in 17 patients but none had received systemic mitoxantrone). No previous local treatment had been attempted. During the study period, no other treatment has been given. Mitoxantrone (6 mg/m2) has been administrated after effusion aspiration. A complete response was seen in 8 patients, a partial response in 5, and no change in the 5 others but one had received only one injection on account of a transitory shock immediately after. No others side effects were reported (fever, local pain, alopecia, vomiting). No patient had evidence of myelosuppression. These results suggest that intracavity injection of mitoxantrone is feasible and generally safe in most patients. Some efficiency has been seen in previously heavily treated patients refractory to systemic chemotherapy. Local administration of mitoxantrone deserves further investigation.

Mitoxantrone was evaluated in a multi-institution trial to define the effective dose for treating acute leukemia, to evaluate its toxicity, and to assess the induction rates for the different types of acute leukemia. Fifty-seven patients have been treated. Of the 24 patients receiving mitoxantrone (10 mg/m2/day X 5), one of nine with acute nonlymphoblastic leukemia (ANLL) in relapse, one of five with acute lymphoblastic leukemia in relapse, and one of seven with blastic chronic myelogenous leukemia achieved remission. At a dose of 12 mg/m2/day X 5, seven of 16 patients with ANLL in relapse, none of six with acute lymphoblastic leukemia in relapse, and one of five with blastic chronic myelogenous leukemia achieved remission. At both dose levels, there was no response in patients who had failed to achieve a prior remission. Toxic effects included nausea/vomiting, stomatitis, and hepatic dysfunction. Nine of the 57 patients treated experienced cardiac events but cardiac toxicity seemed clinically significant in only three. We conclude that mitoxantrone, at a dose of 12 mg/m2/day X 5, is effective therapy for ANLL. Trials combining mitoxantrone with other agents are needed.

Mitoxantrone (Novantrone), is an anthracenedione which in preclinical studies demonstrated a spectrum of antitumor activity similar to the anthracyclines, but with less cardiotoxicity. Novantrone is a cytotoxic agent that produces dose-dependent myelosuppression. When administered to patients intravenously every three weeks, white blood cell (WBC) and platelet nadirs occurred between days 8 and 15 with hematologic recovery by day 22. In multiple clinical trials in over 4450 patients, including 372 patients in randomized trials against Adriamycin, Novantrone was consistently associated with a reduced incidence of moderate and severe acute side-effects. In four randomized trials the adverse experience profile associated with Novantrone was superior to that of Adriamycin with statistically significant lower incidences of mucositis/stomatitis, nausea, vomiting and alopecia. Novantrone was less cardiotoxic than Adriamycin and cardiac events were rare in patients without predisposing risk factors. The high level of activity combined with improved patient tolerance and decreased toxicity make Novantrone a promising agent for patients requiring cytotoxic chemotherapy.

Mitoxantrone (Novantrone; dihydroxyanthracenedione) is an anthraquinone previously shown to be active in human breast cancer. It appears to have less toxicity than doxorubicin. Results of this phase II-III randomized cross-over trial to determine the relative efficacy and toxicity of mitoxantrone in comparison to doxorubicin, are presented. Patients with measurable, recurrent breast cancer with limited prior chemotherapy with or without radiotherapy for metastatic disease, and who had not been exposed to prior doxorubicin, were randomized to receive either mitoxantrone or doxorubicin every three weeks with cross-over on progression. Response rates, duration of remission, time to treatment failure, and drug toxicity, including cardiac toxicity evaluated with serial radionuclide angiocardiography, were evaluated. Differences in the response rates for the two groups were not statistically significant. Neither time to treatment failure nor duration of response are significantly different (p greater than 0.05). With respect to toxicity, mitoxantrone treated patients consistently exhibited a lower incidence and less severe drug toxicity as compared to their doxorubicin-treated counterparts. Cardiac toxicity was carefully monitored and thus four patients on doxorubicin have had drug related congestive heart failure, as compared to none on mitoxantrone. In summary, mitoxantrone appears to be as active as doxorubicin in patients with stage IV breast cancer previously treated with chemotherapy; however, mitoxantrone causes significantly less nausea, vomiting, stomatitis and alopecia at doses which induce equal or greater myelosuppression than doxorubicin, and appears to be less cardiotoxic.

Forty-two women with measurable or evaluable advanced breast cancer who had received neither prior chemotherapy for advanced disease nor any anthracycline-containing regimen as adjuvant were entered in a phase II study of mitoxantrone (Novantrone; dihydroxyanthracenedione). Patients were aged from 36 to 80 years, performance status was from 0 to 2. All patients had normal hematological status and normal renal and liver function tests. Cardiac scintigraphy and sonography techniques were used to monitor cardiac function. Mitoxantrone was administered at a dose of 14 mg/m2 in 100 ml 5% dextrose solution over 30 minutes, repeated every three weeks. The number of courses per patient ranged from 2 to 12. Of 42 eligible patients 39 were fully evaluable for response and all for drug toxicity. Responses to treatment were: complete response four patients, partial response 10 patients, stable disease 18 patients and progressive disease seven patients. The overall response rate was 36% (95% confidence limits 20-52%). Three patients showed decreased left ventricular ejection fraction but no patient developed signs of overt left ventricular failure during the treatment period. Hematological and gastrointestinal toxicities were mild. Hair loss was minimal. The data indicate that mitoxantrone is an effective agent for the treatment of advanced breast cancer with mild side-effects, especially with respect to nausea/vomiting, hair loss and cardiotoxicity.

A randomized trial began in 1980 comparing the efficacy and toxicity of mitoxantrone and doxorubicin. Patients with metastatic breast cancer unresponsive to cyclophosphamide-methotrexate-5-fluorouracil with or without tamoxifen were randomized to either mitoxantrone, 12 mg/m2, or doxorubicin, 60 mg/m2, every 3 weeks. Patients were crossed over to the alternative treatment if they progressed after two courses or fail to respond after four courses. Fifty-nine patients have been randomized at the present time, and most of these have a performance status near to normal. During initial therapy, partial responses were obtained in 10 of 25 patients receiving doxorubicin, and a further 12 showed stable disease; 3 showed progressive disease. Of the 26 patients who received mitoxantrone as initial therapy, 7 achieved a partial response, 14 had stable disease, and 5 progressive disease. Twenty-seven patients received doxorubicin or mitoxantrone as secondary therapy; two patients each responded to these drugs, suggesting a lack of cross-resistance. The median time to response was 48 days for doxorubicin and 57 days for mitoxantrone. The duration of partial responses measured from the onset of response was similar for both drugs, being 84 days for doxorubicin and 96 days for mitoxantrone. Hematologic toxicity, vomiting, alopecia, and fatigue tended to be less frequent and less severe with mitoxantrone than with doxorubicin. Mitoxantrone appears to be an effective and well-tolerated agent for breast cancer. Definitive comparisons will be available at the completion of this study.

A trial of combination chemotherapy using mitoxantrone-cyclophosphamide was started in 1983. Sixteen patients with widely metastatic cancer of the breast, including one man, received mitoxantrone, 10 mg/m2 intravenously (IV) over 30 minutes on day 1, followed by cyclophosphamide, 200 mg/m2 by mouth (PO) daily in divided doses on days 3 to 6. It is too early to evaluate four patients at present. The remaining 12 received three or more courses of treatment, and three of these patients achieved a complete response. Another four patients went into partial remission, amounting to an overall response rate of 58%. The other evaluable patients showed stable disease with improved symptoms. Hematologic toxicity was mainly granulocytopenia, but thrombocytopenia occurred in two patients. Alopecia, nausea, and vomiting were attributed to the cyclophosphamide component of the therapy. Mitoxantrone appeared to have no cardiac toxicity. It was concluded that mitoxantrone-cyclophosphamide is an effective chemotherapeutic combination with minimal toxicity and should be further studied in larger controlled trials.

A phase II study of mitoxantrone, an anthraquinone derivative with structural similarities to adriamycin, has been carried out in 34 patients with advanced breast carcinoma and other malignancies. The first 20 patients were treated with a starting dose of 12 mg/m2 by IV infusion repeated every 3 weeks; this was escalated to 14 mg/m2 in the subsequent 14 patients. Of the 29 patients with advanced breast carcinoma, 8 achieved a partial response and two further patients achieved a mixed response. There were no complete responses. Of the eight responding patients, five had received no prior chemotherapy. Response duration ranged from 3 1/2 months to 10+ months. No responses were seen in the other five patients, three whom had small cell carcinoma of the lung, and one colonic carcinoma. Neutropenia was the most frequently seen toxicity but was usually mild and transient; WBC fell to less than 2,000/mm3 in eight patients and to less than 1,000/mm3 in only two. Otherwise, the drug was well tolerated; nausea occurred in 35% of patients and vomiting in 21%; severe alopecia requiring a wig was never seen. Mitoxantrone appears to be a well-tolerated and clinically active agent against advanced breast carcinoma.
