Mitoxantrone is a dihydroxyanthracenedione derivative which as intravenous mono- and combination therapy has demonstrated therapeutic efficacy similar to that of standard induction and salvage treatment regimens in advanced breast cancer, non-Hodgkin's lymphoma, acute nonlymphoblastic leukaemia and chronic myelogenous leukaemia in blast crisis; it appears to be an effective alternative to the anthracycline component of standard treatment regimens in these indications. Mitoxantrone is also effective as a component of predominantly palliative treatment regimens for hepatic and advanced ovarian carcinoma. Limited studies suggest useful therapeutic activity in multiple myeloma and acute lymphoblastic leukaemia. Regional therapy of malignant effusions, hepatic and ovarian carcinomas has also been very effective, with a reduction in systemic adverse effects. Mitoxantrone inhibits DNA synthesis by intercalating DNA, inducing DNA strand breaks, and causing DNA aggregation and compaction, and delays cell cycle progression, particularly in late S phase. In vitro antitumour activity is concentration- and exposure time-proportional, and synergy with other antineoplastic drugs has been demonstrated in murine tumour models. Leucopenia may be dose-limiting in patients with solid tumours, whereas stomatitis may be dose-limiting in patients with leukaemia. Other adverse effects are usually of mild or moderate severity although cardiac effects, particularly congestive heart failure, may be of concern, especially in patients with a history of anthracycline therapy, mediastinal irradiation or cardiovascular disease. Mitoxantrone displays an improved tolerability profile compared with doxorubicin and other anthracyclines, although myelosuppression may occur more frequently. Thus, mitoxantrone is an effective and better tolerated alternative to the anthracyclines in most haematological malignancies, in breast cancer and in advanced hepatic or ovarian carcinoma. Further studies may consolidate its role in the treatment of these and other malignancies.

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 is an antitumor agent that was synthesized to try to develop a doxorubicinlike drug with a better therapeutic index. It has clinical activity for acute leukemias, breast carcinoma, non-Hodgkin's lymphoma, and ovarian cancers. There is some lack of cross-resistance to the anthracyclines. Its spectrum of toxicity is advantageous in that it causes less alopecia and can be administered for a slightly longer time than doxorubicin. For selected patients, mitoxantrone can be useful as a substitute for doxorubicin, but doxorubicin will remain the more widely used drug.

Mitoxantrone (Novantrone, NO) and high-dose cytarabine (Ara-C, AC) have each been shown in monotherapy trials to be active in non-Hodgkin's lymphoma (NHL). In the current study, a combination of the two drugs (NOAC) was administered to 31 patients with advanced NHL refractory to modern sequential chemotherapy regimens. Ara-C was administered at 3 g/m2 as a 3 hour infusion every 12 hours on day 1 (2 doses) and mitoxantrone at 10 mg/m2/day on days 2 and 3. Of the 18 patients with high-grade malignant NHL, six have attained a complete remission (CR) and two, a partial remission (PR). One CR and 5 PRs were achieved among the other 13 patients with intermediate or low-grade NHL. The median time to relapse (TTR) of patients achieving CR was 7 months with a range from 4 to 17 months. Myelosuppression with subsequent infections was the major toxicity of this regimen. The median duration of severe neutropenia (less than 0.5/nl) was 9 days with a range of 0 to 27 days and the median duration of severe thrombocytopenia (less than 20/nl), 5 days with a range of 0 to 35 days. Infectious complications during cytopenia was seen in 45.3% of the courses administered and fever of unidentified origin was seen in 42.3%. About 63% of the patients were hospitalized for intravenous antibiotic or antimycotic treatment. Other side effects were mild and included nausea, stomatitis, and transient tachycardia of greater than 100/min. Thus, this regimen was active in refractory NHL with poor prognosis, and the toxic side effects were not excessive. Evaluation of the activity of this regimen at higher dose levels of Ara-C is warranted.

Mitoxantrone is an anthraquinone antineoplastic agent with structural similarities to doxorubicin. It has a mechanism of action similar to the anthracyclines. Its primary elimination route is hepatic metabolism (only seven percent renal excretion) and it has a terminal half-life of approximately 40 hours. Mitoxantrone has significant activity in the treatment of metastatic breast cancer, acute leukemias, and non-Hodgkin's lymphoma. Some activity is reported in head and neck cancer, Hodgkin's, myeloma, bladder cancer, prostate cancer, non-small-cell lung cancer, and liver cancer. There is a suggestion of incomplete cross-resistance between mitoxantrone and the anthracyclines in certain neoplasms. Some activity is reported with mitoxantrone in patients refractory to the anthracyclines in breast cancer, acute leukemias, and non-Hodgkin's lymphomas. The usual doses used in solid tumors and in lymphomas are mitoxantrone 12-14 mg/m2 iv q3-4wk and in leukemias is mitoxantrone 12 mg/m2/d X 5 d iv for initial induction.

In order to compare the efficacy and toxicity of mitoxantrone and adriamycin in non-Hodgkin's lymphoma, a randomized trial has been conducted by a cooperative study group since June 1984. Previously untreated patients with non-Hodgkin's lymphoma of intermediate-grade-malignancy were allocated to either MCOP (a combination of mitoxantrone, cyclophosphamide, vincristine, and prednisolone) or CHOP (a combination of adriamycin, cyclophosphamide, vincristine, and prednisolone) regimens. Forty-four patients were entered and 43 of these were fully evaluated for tumor response and toxicity. The complete remission rate was 80% for 20 patients receiving MCOP compared to 61% for 23 patients treated with CHOP. Response duration and overall survival were similar for the two treatments. Toxicity was almost comparable for the two treatments. Only alopecia was significantly less frequent in patients given MCOP than in those receiving CHOP. Mitoxantrone thus appears to be as effective as adriamycin in the treatment of non-Hodgkin's lymphoma.

A phase II clinical trial of mitoxantrone in refractory or relapsed malignant lymphomas was conducted by a cooperative study involving 17 institutions. Of 46 patients entered, 33 were evaluable for responses and toxicity. Thirty-one of the 33 had been previously exposed to adriamycin at a median dose of 220 mg/m2 (range 21-489 mg/m2), and two additional patients had each been given THP-adriamycin at a dose of 80 mg/m2 or 4'-epi adriamycin at a dose of 69 mg/m2. Mitoxantrone was administered in 3 different schedules: 8-12 mg/m2, every 3-4 weeks in 23 patients; 4-6 mg/m2, weekly, in 3 patients; and 2-4 mg/m2, for 5 days, in 7 patients. Summarizing the responses obtained in the 3 schedules, there were 2 partial responders among 5 with Hodgkin's disease, while there were 8 complete responders and 4 partial responders among 28 with non-Hodgkin's lymphoma. The overall response rate for all the evaluable patients was 42% with a complete response rate of 24%. The median response duration was 7+ weeks (range 4-27+ weeks) for complete responders and 7 weeks (range 4-46+ weeks) for partial responders. The major toxicity was myelosuppression: leukocytopenia less than 3,000/microliter occurred in 79% of patients, and thrombocytopenia less than 75,000/microliter in 35%. Other toxic effects were minimal, mild nausea and/or vomiting occurred in 39%, and diarrhea in 3%. Possible drug-related liver and renal dysfunctions were observed in 19% and 10%, respectively. The favorable response to mitoxantrone in patients with prior anthracycline antibiotic therapy suggests that the drug is not fully cross-resistant with anthracycline antibiotics, and that this drug is of value in combination with other drugs as a salvage therapy for patients with refractory or relapsed malignant lymphomas.

We have used a highly sensitive high-performance liquid chromatographic assay to evaluate the pharmacokinetics and tissue disposition of mitoxantrone, an investigational anthracene derivative which has shown significant activity during Phase II clinical trials in the treatment of metastatic breast cancer, unfavorable histology non-Hodgkin's lymphoma, and acute leukemia. Mitoxantrone (12 mg/sq m over 30 to 35 min in 250 ml of dextrose 5% in water) and 14C-labeled mitoxantrone (specific activity, 8.85 muCi/mg) were administered to eight patients who had advanced soft tissue cancers. The plasma disappearance of mitoxantrone concentrations measured by high-performance liquid chromatography was best described by a three-compartment model with a mean t alpha of 0.1 h, a t beta of 1.1 h, and a t gamma of 42.6 h. The mean apparent Vc was 12.2 liters/sq m, while the mean Vd was 1875 liters/sq m. The mean plasma clearance was 0.57 liters/min/sq m, and the mean renal clearance was 45 ml/min/sq m. Only 6.5% of the total mitoxantrone dose was excreted in the urine as unchanged drug over 5 days. The mean recovery of 14C-labeled material in feces over 5 days was 18.3% of the administered dose. Thirty-five days after mitoxantrone administration to a patient who died of progressive kidney cancer, approximately 15% of the 14C dose could be accounted for in seven major organs. We conclude that mitoxantrone appears to distribute into a deep tissue compartment from which it is slowly released. These data provide a pharmacological rationale for use of mitoxantrone on an intermittent dosing schedule.

We have utilized a recently developed human tumor cloning system to screen for antitumor effects in vitro of a new anthracenedione derivative, Mitoxantrone. The object was to determine if the system is useful for pinpointing the types of tumors in patients which should be studied in early Phase II clinical trials. Tumors from 267 patients were placed in culture (20 different histological tumor types). One hundred seventy tumors both grew and formed enough colonies for drug sensitivity assays. Excellent in vitro antitumor activity was noted for Mitoxantrone against human adenocarcinoma of the lung, small cell lung cancer, melanoma, and biliary tree cancer. Good antitumor activity was noted against breast cancer, ovarian cancer, non-Hodgkin's lymphoma, head and neck cancer, squamous cell lung cancer, soft tissue sarcoma, gastric cancer, and hepatomas. The drug showed no in vitro activity against colon cancer. These data indicate that Mitoxantrone has a wide spectrum of in vitro antitumor activity. A comparison of these in vitro results with the results of Phase II clinical trials with the drug should allow an evaluation of the utility of the human tumor cloning system for predicting clinical antitumor activity of a new compound.
