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.

Diaziquone (AZQ), a synthetic quinone with demonstrated activity against acute nonlymphocytic leukemia (ANLL), primary CNS tumors, and non-Hodgkin's lymphoma (NHL), is virtually devoid of nonhematopoietic toxicity at conventional doses. As a prelude to its inclusion into bone marrow transplant (BMT) preparative regimens, a phase I study of high-dose AZQ with autologous BMT (ABMT) was performed. Patients with refractory solid tumors and lymphomas were treated with a single 24-hour infusion of AZQ at 50 to 355 mg/m2 in dose escalations of 20%. Fifty-six patients received 69 courses. Those receiving greater than 60 mg/m2 had nadir granulocyte and platelet counts less than 500/microL and 20,000/microL, respectively. Nausea, vomiting, stomatitis, and diarrhea were mild, transient, and not dose-related. Transient minimal elevations of liver function tests were seen in five patients and were also not dose-related. The maximally tolerated dose (MTD) of high-dose AZQ was found to be 245 mg/m2, with nephrotoxicity being dose-limiting. Significant azotemia was seen in four of 12 patients treated at 295 and 355 mg/m2, including fatal anuric renal failure in three of these patients. Reversible proteinuria also occurred in 24 of 26 courses above 150 mg/m2, including nephrotic range proteinuria in eight courses, all at doses of 205 to 355 mg/m2. The proteinuria was also associated with multiple proximal tubular defects including generalized aminoaciduria and proximal renal tubular acidosis. There were six early deaths including two of early renal failure (295 and 355 mg/m2), two of sepsis (205 and 245 mg/m2), one of a pulmonary embolus (85 mg/m2), and one of progressive disease (60 mg/m2). Of 50 patients who were assessable for response, there were seven responses including two of 10 with primary CNS tumors, one of 12 with malignant melanoma, one of five with non-small-cell lung carcinoma, two of two with breast carcinoma, and one of one with ovarian carcinoma. Because of its activity in ANLL and NHL and its unique toxicity spectrum, high-dose AZQ may improve the efficacy of current BMT preparative regimens without significantly increasing their nonhematopoietic toxicity.

An important subset of malignancies arising in the ovary or digestive organs remains confined to the peritoneal cavity throughout its natural course. These tumors constitute appropriate targets for loco-regional therapy. With this rationale a clinical phase I and pharmacokinetic study of intraperitoneally administered N, N', N'' triethylenethiophosphoramide (thiotepa), an alkylating agent with activity against ovarian carcinoma, was initiated with the objectives of determining the systemic and local toxicities, maximum-tolerated dose, and pharmacokinetic advantage associated with using the drug in this manner. A total of 13 patients received 15 courses of intraperitoneal thiotepa at doses ranging from 30 mg/m2 to 60 mg/m2. The only important systemic toxicity observed was myelosuppression. At 50 mg/m2 two patients developed Eastern Cooperative Oncology Group (ECOG) grade III myelosuppression. At 60 mg/m2, the maximum-tolerated dose, the mean nadir WBC and platelet counts were 2.7 X 10(3)/microliter and 110 X 10(3)/microliter, respectively. There were no instances of vomiting, stomatitis, or alopecia. Pharmacokinetic studies performed in nine patients revealed that thiotepa was rapidly lost from the peritoneal cavity in a biexponential fashion with a mean t1/2 alpha of 0.26 +/- 0.08 hour and a mean t1/2 beta of 2.13 +/- 0.52 hour. Concomitant with the rapid loss of drug from the peritoneal cavity was the rapid rise in drug levels in the plasma, with peak plasma values approaching those associated with intravenous administration. Peritoneal exposure to thiotepa expressed as the area under the curve (AUC)peritoneal fluid was 7 to 34 micrograms/mL X hour. Systemic exposure expressed as the AUCplasma ranged between 0.95 and 7.71 micrograms/mL X hour. The observed pharmacokinetic advantage of intraperitoneal administration calculated as AUCperitoneal fluid/AUCplasma was 4.3 +/- 0.6. This relatively small advantage, combined with our observation of rapid appearance of the active metabolite, tepa, into the plasma argue against an important role for intraperitoneal administration of thiotepa.

Etoposide (VP 16) is a semi-synthetic derivative of 4'- demethylepipodophyllotoxin , a naturally occurring compound synthesized by the North American May apple (Podophyllum peltatum ) and the Indian species Podophyllum emodi Wallich . Although podophyllotoxins are classical spindle poisons causing inhibition of mitosis by blocking mitrotubular assembly, etoposide inhibits cell cycle progression at a premitotic phase (late S and G2), probably via inhibition of DNA synthesis. There appears to be a selective antileukemic dose response relationship when compared to normal hematopoietic elements. Etoposide is effective when administered orally at about twice the recommended parenteral dosage. Schedule dependency in both animal models and clinical trials has been observed; multiple dosing over three to five consecutive days is superior to weekly single dose administration. Etoposide's dose-limiting toxicity is myelosuppression (leukopenia), which is quite predictable; alopecia and Gl toxicity (nausea, vomiting, stomatitis) occur in about 20-30% of patients given recommended dosages. Etoposide appears to be one of the most active drugs for small cell lung cancer, testicular carcinoma (the Food and Drug Administration approved indication), ANLL and malignant lymphoma. Etoposide also has demonstrated activity in refractory pediatric neoplasms, hepatocellular, esophageal, gastric and prostatic carcinoma, ovarian cancer, chronic and acute leukemias and non-small cell lung cancer, although additional single and combination drug studies are needed to substantiate these data. Its contribution in front-line combination chemotherapeutic regimens for these cancers will be better defined in the forthcoming years. Etoposide appears to have minimal activity in breast cancer and, based on current data, it is inactive against malignant melanoma, colorectal adenocarcinoma and cancer of the head and neck, although the dosage and schedules used in many of the Phase II studies may have been suboptimal.

THP-ADM is a new antitumor antibiotic which belongs to the anthracycline group. This agent was administered to 42 histology proven various malignant disease patients with a schedule of 60-80 mg per body (40-55 mg per m2) iv bolus, every three weeks. THP-ADM administration revealed mild upper GI toxicity (vomiting 19%, stomatitis 21%) and leukopenia (less than 2,000 per mm3) in 80% and thrombocytopenia (less than 60,000 per mm3) in 38% with good rebound. There was no signs or symptoms of cardiac failure including the patient who had received 740 mg per body (500 mg per m2). Definite response (CR, PR) was observed in ovarian carcinoma 4/11, cervix carcinoma 2/7, breast carcinoma 1/6, malignant lymphoma 5/5 and mesothelioma 1/2. Furthermore, some response (MR) was observed in lung metastasis from endometrial carcinoma 2/4, and stomach carcinoma 1/3. The above indicated usefulness of this agent and further study should be continued, especially a controlled study with adriamycin.

A phase I clinical trial of N-phosphonacetyl-L-aspartic acid (PALA) and 5-fluorouracil (FUra) was performed on 30 patients. PALA was given as a 15-minute iv infusion once daily for 5 days, and FUra was given as a bolus injection on days 2, 3, 4, and 5. Cycles of treatment were repeated every 3 weeks. Dose-limiting toxicity was manifested by stomatitis and diarrhea. Skin rash was observed also but was not dose limiting. No consistent hematopoietic or renal toxicity was observed. Seventeen patients with disseminated metastatic melanoma and measurable disease were evaluated for response. One partial response was seen; however, the response was associated with significant toxicity, and the treatment could not be repeated. Stable disease was observed in 3 patients with melanoma, 1 patient with colon carcinoma, and 1 patient with ovarian carcinoma. Our findings suggest that the clinical activity of PALA and FUra given according to the above schedule for melanoma is less than 25% (P less than 0.05). Pharmacokinetic studies of FUra revealed no consistent effect of PALA pretreatment on FUra disappearance in plasma. The mean FUra elimination half-line in plasma was 7.11 +/- 0.84 minutes (SEM), which is no different from that reported for FUra alone. The recommended doses on this schedule for phase II studies are 1,000 mg PALA/m2/day iv daily for 5 days and 200 mg FUra/m2/day iv on days 2, 3, 4, and 5.

We carried out a phase II study on single oral administration of UFT in 17 patients with ovarian carcinoma. Two PR cases were observed out of 13 evaluable cases for a response rate was 15.4%. Side-effects, appearing in 10 of the cases (58.8%) were mainly anorexia (17.6%), stomatitis (17.8%), nausea/vomiting (11.8%), leukopenia (11.8%) and thrombocytopenia (11.8%), but they were not serious. UFT proved useful in the treatment of patients with ovarian carcinoma.

Thirty-nine women with advanced, recurrent epithelial ovarian carcinoma who failed prior treatment with a platinum-based regimen were treated with leucovorin, 20 mg/m2 intravenously followed by 5-fluorouracil, 425 mg/m2 intravenously, daily for 5 consecutive days every 5 weeks in a phase II trial. Partial regressions were seen in 3 of 15 (20%) measurable disease patients, and objective regressions were seen in 3 of 14 (21%) evaluable/nonmeasurable disease patients. A 50% or greater decrease in CA-125 level was observed in 3 of 10 (30%) patients with no objectively evaluable or measurable disease. Overall objective response rate was 23% (95% confidence interval: 11 to 39%) in all 39 patients evaluated, with a median time to progression of 3 months and overall median survival of 7 months. Toxicities were acceptable and consisted of neutropenia, thrombocytopenia, stomatitis, and mild diarrhea. 5-Fluorouracil, as administered in this protocol, had modest antitumor activity in cisplatin-refractory ovarian carcinoma of short duration and minimal toxicity.

A combination of platinum and a taxane is regarded by many as the optimum treatment for advanced epithelial ovarian carcinoma. A recent meta-analysis has suggested that the addition of an anthracycline to platinum-based chemotherapy is associated with a significant survival advantage. We are therefore conducting an ongoing phase I/II study combining drugs from these three classes. We report here the first phase using carboplatin at an area under the concentration-time curve of 7, doxorubicin 50 mg/m2, and paclitaxel (Taxol; Bristol-Myers Squibb Company, Princeton, NJ) 175 mg/m2 over 3 hours. The treatment was given on a 3-weekly cycle and granulocyte colony-stimulating factor was given if the nadir neutrophil count fell below 0.5 x 10(9)/L and was continued until recovery. Toxicity was assessed according to the Common Toxicity Criteria. All patients were required to have advanced ovarian cancer (stage IC to IV) but be ineligible for standard chemotherapy trials or to have advanced gynecologic malignancy, such as mixed mullerian tumor, fallopian tube carcinoma, coelomic carcinoma, or primary peritoneal carcinoma. To date, seven patients have been treated, and all were of performance status 0 to 2, 18 to 70 years old, with a life expectancy of > or = 3 months. Hematologic toxicity was significant, with all patients having grade 3/4 thrombocytopenia and six of seven grade 3/4 leukopenia. There was, however, only one grade 3/4 infection. Three patients have experienced fatigue, which in two cases was severe, and one patient had grade 3/4 stomatitis. Dose reduction was due to myelosuppression and was required in five patients. Five patients were evaluable for response, all of whom have obtained complete or partial response. There has been no clinical evidence of cardiotoxicity, but four patients had grade 1/2 cardiotoxicity as measured by left ventricular ejection fraction. We conclude that this combination is active and has acceptable but significant toxicity. It is only suitable for very fit patients, and we are currently assessing ways of reducing toxicity.

We analyzed the efficacy and toxicity of docetaxel in patients with ovarian cancer who failed previous chemotherapy with platinum. Fifty-five patients with measurable ovarian cancer were entered in this Phase II study at The University of Texas M. D. Anderson Cancer Center. Treatment consisted of 100 mg/m2 docetaxel given i.v. every 3 weeks. Because of hypersensitivity reactions, premedication with steroids and antihistamine was initiated during the study. Twenty-two (40%) patients responded (there were 3 complete responders and 19 partial responders). Twenty-one (38%) patients had stable disease. The median survival was 10 months. The main toxicity was neutropenia (98% of patients), with 13 episodes of neutropenic fever. Cumulative fluid retention was the main reason for dose modification and required a combination of diuretics and steroids for palliation. Other side effects were alopecia (100%); anemia (87%); dermatitis (67%); gastrointestinal disorders (53%); stomatitis (49%); neurotoxicity (45%); excessive lacrimation (33%); and hypersensitivity reactions (11%), which in one case were life threatening (loss of consciousness, fluid resuscitation). Docetaxel as a single agent proved to be active in heavily pretreated ovarian cancer patients but is associated with significant side effects. Objective toxicity consisted mainly of neutropenia and fluid retention. Neutropenia was dose limiting and required therapy with granulocyte colony-stimulating factor. Fluid retention was improved but not eliminated by diuretics and corticosteroids. Additional studies of docetaxel in ovarian carcinoma are indicated to define the activity in relation to paclitaxel and in platinum combination therapy.
