Phase II Study of UFT was performed in 59 patients with malignant tumors of urinary organs in 5 Cooperative Study Institutions. Forty-nine patients out of 59 were evaluable for response according to Koyama -Saito's criteria. Complete response (CR) was recorded in 7 patients, partial response (PR) in 3, minor response in 2, no change in 27 and progressive disease in 10, respectively. The overall response rate was 20.4%. The response classified in terms of tumor type was as follows: 4 CR and 2 PR of 23 patients with bladder tumor, response rate of 26.1%; 1 CR and 2 PR of 10 patients with renal tumor, response rate of 30.0%; 1 CR of 12 patients with prostatic tumor, response rate of 8.3%. Side effects occurred in 22 (41.5%) out of 53 patients. The high incidence was mainly concerned with GI toxicity such as anorexia (24.5%), nausea and vomiting (9.4%), general malaise (9.4%), diarrhea (3.8%) and stomatitis (3.8%), respectively. Renal function disorder was not induced, and marrow depression and hepatic function disorder occurred at low frequency (1 case each).

A phase II study of KW 2083 [7-N-(p-Hydroxyphenyl)-Mitomycin C] was carried out in 14 cases of stomach cancer, 5 of lung cancer, 5 of colon cancer and 5 other types of cancer. KW 2083 was intravenously injected at a dose of 40 mg/body weekly in 26 cases. Among 23 evaluable cases, partial response was obtained in 6 cases (26%). The PR cases were 4 of stomach cancer and 2 of lung cancer, the former being all undifferentiated adenocarcinoma. Regarding hematologic toxicities, thrombocytopenia was the most principal toxicity and an important weak point of KW 2083. Thrombocytopenia (less than 75,000/mm3) was observed in 13 cases (50%). Recovery took about 4 weeks, but by that time 3 cases had still not recovered to 75,000/mm3. leukocytopenia (less than 3,000/mm3) was observed in 17 cases (65%). Concerning gastrointestinal symptoms, anorexia occurred in 11 cases (42%), nausea and vomiting in 11 cases (42%), diarrhea in 1 case and stomatitis in 1 case. T1/2 (beta-phase) of KW 2083 was half that of Mitomycin C.

4-Demethoxydaunorubicin (4-DMDR), an anthracycline analogue available in i.v. and p.o. form, has shown significant antitumor activity in murine tumor models while producing less cardiac toxicity than doxorubicin at equimyelotoxic doses. Phase I and clinical pharmacology studies of the i.v. and p.o. preparation were performed. With i.v. 4-DMDR, consistent myelosuppression was observed at a dose of 15 mg/sq m at a median Day 15; mild nausea and vomiting were observed in 9% of all treatment courses. In patients given p.o. 4-DMDR, myelosuppression occurred at median Day 14 in 10 of 12 patients given 50 mg/sq m. Nausea and vomiting occurred in 25% of all treatment courses, and dividing the dose over 3 days did not decrease the incidence. Alopecia occurred in 13% of evaluable patients treated with the i.v. preparation and 30% of evaluable patients treated p.o. No stomatitis was observed with either preparation, and no patient developed clinical signs of congestive heart failure. Pharmacokinetic studies were performed with both preparations and revealed prolonged plasma levels of the 13-hydroxy metabolite 4-DMDR-ol. The suggested starting dose for Phase II studies is 12.5 mg/sq m given every 21 days for i.v. 4-DMDR with dose escalation by 2.5 mg/sq m in the absence of myelotoxicity. For p.o. 4-DMDR, the suggested starting dose is 40 mg/sq m given every 21 days with escalation by 10 mg/sq m if no myelotoxicity is observed.

Quinone derivatives have shown intensive antitumor activity in a broad variety of neoplasias. Aziridinylbenzoquinone is designed to have adequate lipid solubility to attain useful drug concentrations in the central nervous system. A Phase I study of aziridinylbenzoquinone was conducted in 32 patients with advanced solid cancers. The drug was given as a slow i.v. injection on Days 1, 8, 15, and 22 of a 42-day cycle with a 2-week rest. Five dose levels ranging from 5 to 20 mg/sq m were studied, with 3 to 10 patients treated at each level; a total of 156 doses were administered. The major toxicity was myelosuppression with the median nadir in platelet and white blood cells occurring at Days 15 to 27 of the cycle, and first appearing at doses greater than 10 mg/sq m. Anemia was first seen at the 10-mg/sq m dose level, occurring between Days 22 and 40. Nonmyelosuppressive toxic effects included nausea and vomiting, anorexia, diarrhea, stomatitis, slight alopecia, and transient fever. The highest tolerated dose was 20 mg/sq m, the recommended dose for Phase II studies. Plasma and urine pharmacokinetics were studied in 17 patients by a high-pressure liquid chromatography method. Plasma decay curves could be fitted to a two-compartment open-system model with an overall average alpha and beta half-life values of 10.5 +/- 6.28 min and 16.90 +/- 8.63 (S.D.) hr. Aziridinylbenzoquinone levels were determined in urine samples of 12 patients, but less than 0.1% of the dose was excreted in the 0- to 4-hr sample of two patients, and none was detected in the urine of 10 patients.

Marcellomycin, a new anthracycline antibiotic, was administered intravenously on a weekly schedule to 22 patients with advanced malignant solid tumors. Patients were treated at 6 dosage levels ranging from 5 to 30 mg/m2 weekly for 4 weeks. Courses were repeated after a 3-week rest period. Hematologic toxicity was dose-limiting but unpredictable. Of 10 patients treated with weekly doses of 27.5 mg/m2, 3 patients exhibited myelosuppression and 2 died in agranulocytosis. Moderate to severe nausea and vomiting occurred in 19 of 22 evaluable patients. Other toxic effects were non-acute and consisted of mild stomatitis, diarrhea, phlebitis and moderate fatigue in 1-3 patients each. In 17 patients evaluable for antitumor activity no partial or complete responses occurred. One patient with advanced breast cancer showed a mixed response. Marcellomycin given on a weekly dose schedule has unpredictable and erratic hematologic toxicity. The maximally tolerated dose appears to be between 27.5 and 30 mg/m2 weekly. However, no firm recommendations can be given for a dose level that results in tolerable, predictable and reversible toxicity.

This study was designed to evaluate the usefulness of Coenzyme Q10 (CoQ10) in the prevention of side effects due to anthracycline agents-Adriamycin (ADM) and Daunorubicin (DNR)-by comparing the preventive effect between CoQ10-treated and non-treated groups. The subjects were 79 patients, 55 of whom had malignant lymphoma. The age range was from 16 to 77 years with a mean age of 45.4 years. CoQ10 was administered by intravenous drip at 1 mg/kg/day the day before ADM or DNR administration, on the day and for a further 2 days after administration. In mean total dose, complete remission rate and mortality, no significant differences were observed between the 2 groups. Although there were also no significant differences in the degree of alopecia, fever, nausea and vomiting, the incidences of diarrhea and stomatitis were significantly (p less than 0.10 and p less than 0.05, respectively) reduced in the CoQ10-treated group. Depression of ST waves (more than 0.05 mV) and changes in T waves (R/10 greater than T, flat, inversion) on ECG were regarded as a parameter of aggravation. Such ECG aggravation was found in 20 of 40 patients given CoQ10 (50.0%) and in 18 of 25 receiving none (72.0%); a cardiotoxicity-inhibiting tendency was thus evident (p less than 0.10). In heart rate, tachycardia was noted in the nontreated group when the period of use of anthracycline agents exceeded 8 weeks. Twenty nine patients received ADM or DNR for 8 weeks or more, and, of them, 17 were treated with CoQ10; 11 of the 17 (64.7%) showed ECG aggravation, while 11 of 12 patients (91.7%) not treated with CoQ10 showed ECG aggravation. A tendency to depress ECG aggravation was thus observed in the treated group (p less than 0.10).

A Phase I trial of tricyclic nucleoside phosphate (1,4,5,6,8-pentaazaacenaphthylene-3-amino-1, 5-dihydro-5-methyl-1-beta-D-ribofuranosyl 5'-phosphate ester; NSC 280594) was conducted using a 5-day continuous infusion schedule. Thirty-seven patients with advanced cancer were entered on the study, of whom 33 patients were evaluable for response and toxicity. Dose levels ranged from 10 mg/sq m/day X 5 days to 40 mg/sq m/day X 5 days. Initially, courses were repeated every 3 to 4 weeks. As cumulative toxicity became manifested, the interval between courses was changed to every 6 weeks. Major toxicities included hyperglycemia, hepatotoxicity, and thrombocytopenia. Patients with a prior history of diabetes mellitus, extensive radiation therapy, or significant liver metastases were prone to severe toxicity. Other toxicities noted were nausea and vomiting, abdominal discomfort, anemia, and reduction in serum calcium, phosphorus, and albumin levels. Rare side effects included hypertriglyceridemia, hyperamylasemia, diarrhea, and stomatitis. Antitumor activity observed include improvement in s.c. metastases in a patient with papillary thyroid carcinoma, stabilization of disease in a patient with mesothelioma, and mixed responses in three patients (colon cancer, sarcoma, and tonsillar squamous cell cancer). Recommended schedule for Phase II studies is 20 mg/sq m/day for 5 days every 6 weeks.

Thirty-seven patients with acute leukemia in relapse were treated with a three-drug combination that included a 3- or 4-day course of AMSA with total doses ranging from 600 mg/m2 to 740 mg/m2 I.V., cytosine arabinoside 25 mg/m2 I.V. followed by 200 mg/m2 by continuous infusion daily for 5 days, and thioguanine 100 mg/m2 p.o. q 12h for 5 days. Eight of the 25 patients with acute nonlymphoblastic leukemia achieved a complete remission and 3 a partial remission. None of the five patients with acute lymphoblastic leukemia achieved a response and there was one partial remission in the seven patients with myelodysplastic syndrome or blastic CML. Reversible toxicity included nausea and vomiting (78%), alopecia (100%), pancytopenia (100%), mild stomatitis (63%), and hepatic dysfunction (24%). One patient developed seizures and cardiac arrhythmias. The activity of this combination in heavily treated patients with ANLL is comparable to that of the anthracycline-containing regimens, and its use in previously untreated patients with ANLL should now be explored.

Thirty-two patients with relapsed or resistant acute leukaemia were treated with m-AMSA at doses ranging from 50-150 mg/m2 daily for 5 days. Complete remission was achieved in three of 18 patients with acute myeloblastic leukaemia, two of nine patients with acute lymphoblastic leukaemia, and none of five patients with blastic crisis of chronic myeloid leukaemia. The complete remissions all occurred at doses of 100 mg/m2 per day or above. Haematological toxicity occurred in all patients and was dose-related. Nausea and vomiting were mild and easily controlled. Alopecia was uncommon at the lower doses but occurred in all patients receiving the higher doses. Stomatitis was noted in only 8% of courses at 50 mg/m2 but was seen in 50% of courses at 150 mg/m2. Mild and transient elevations of liver enzymes were common. m-AMSA is an active drug in acute leukaemia, with acceptable toxicity. Its place in combination chemotherapy is now being explored.

AMSA was evaluated in the treatment of 109 adults with previously treated acute leukemia. Of the 102 evaluable patients, 82 had AML, 17 ALL, and 3 CML in blastic phase. A number of different dose schedules of AMSA were explored, and we conclude that the optimum dose of AMSA for remission induction in acute leukemia is 120 mg/sq m/day for 5 days. Complete remissions were observed in 23 (28%) patients with AML and in 1 patient with ALL. Patients who achieved complete remission were maintained on AMSA using a dose of 30-40 mg/sq m/day for 5 days repeated at 4-wk intervals. The median duration of complete remission was 12 wk (3-59 wk), and the responders survived significantly longer than the failures (27 wk versus 8 wk, p = 0.002). The side effects associated with AMSA therapy included mild nausea and vomiting, stomatitis, diarrhea, phlebitis, alopecia, and myelosuppression-related infections. Our results indicate that AMSA is a useful new antileukemic agent for the treatment of relapsed acute leukemia and appears to have activity comparable to that of the currently available drugs, such as cytarabine and the anthracycline antibiotics.
