Thirty-three patients with metastatic breast cancer who have failed prior combination chemotherapy including adriamycin, cyclophosphamide, 5-fluorouracil and methotrexate, were treated with AZQ given on a 5-day I.V. schedule repeated every 4 weeks. The starting doses were 6 or 8 mg/m2/day for poor- and good-risk patients, respectively. There were two partial responses among 29 evaluable patients. Both had soft tissue and/or lymph node involvement. Six patients had stable disease. Myelosuppression, predominantly thrombocytopenia, was dose-limiting. Other toxicities were mild, including nausea, vomiting, anorexia, diarrhea, stomatitis, and malaise. Our results indicate that AZQ given on the 5-day schedule is unlikely to be effective in the treatment of refractory breast cancer.

Phase II study of cis-diaminedichloroplatinum(II) (CIS-DDP) administered intravenously was performed in 77 patients with urologic malignancies for the evaluation of clinical responses and adverse effects. The eligibility of the patients and evaluation of response were carried out according to the general criteria proposed by Drs. Koyama and Saito. Out of 85 patients, entered in this phase II study, 77 patients were considered evaluable. Complete responses were seen in 4 patients, 3 testicular tumor and 1 bladder cancer. Partial response were obtained in 24 patients; 10 bladder cancer, 8 testicular tumor, 5 prostatic cancer, and 1 renal cell carcinoma. Overall response rates were 73.3% in testicular tumor, 50.0% in bladder tumor, 20.8% in prostatic cancer, and 7.7% in renal cell carcinoma. Incidences of toxicities were noted in the gastrointestinal tract. Nausea, vomiting, anorexia, abdominal pain, and diarrhea were observed in 78.5% of the patients treated with CIS-DDP. Myelosuppression, lassitude, renal and hearing dysfunction were other prominent adverse effects.

Fifty-one patients with metastatic non-small-cell lung cancer (NSCLC) were treated with VP-16-213 (4'-demethylepipodophyllotoxin) during a phase II trial. Of the 49 patients who had adequate trials, 2 patients achieved a partial response (PR), for an overall 4% major response rate. The median Karnofsky performance status (PS) was 80%; 85.7% of patients had adenocarcinoma and 14.2% had epidermoid carcinoma. Prior treatment with chemotherapy may have adversely affected response rate; the two responses occurred among the 25 previously untreated patients, while no responses were seen in patients who had previously received chemotherapy. Myelosuppression was the most frequent side effect and two drug-related deaths due to septicemia occurred. Other toxic effects noted included anorexia, nausea and hypotension during drug infusion. We conclude that VP-16-213 has minimal activity as a single agent in NSCLC.

Fifty-one patients with non-small cell lung cancer (NSCLC) were treated, during a phase II trial, with 4'demethylepipodophyllotoxin-beta-D-ethylidene glucoside (VP16-213). Forty-nine were evaluable for response, and of these two (4%) had partial responses lasting 5 and 6 months. Prior treatment with chemotherapy may have adversely affected response rate; none of the 24 previously treated patients had a major response. Myelosuppression was the dose limiting toxicity. Anorexia, nausea and vomiting, partial alopecia, and chills plus hypotension during drug infusion were the other toxic effects. We conclude that VP16-213 has only minimal activity as a single agent in NSCLC.

A phase I study of human lymphoblastoid interferon (IFN-alpha) was undertaken in patients with acute leukaemia and other malignancies. The pharmacokinetics of intravenous IFN-alpha were also investigated. IFN-alpha was administered to two patients by intravenous (IV) bolus injection at a dose of 5 X 10(6) U/m2; and to a further 37 patients (40 cycles) by continuous intravenous infusion (IVI) for 5, 7, or 10 days at doses ranging from 5 to 200 X 10(6) U/m2/day. Pyrexia, general malaise, anorexia, and rigors were observed at all dose levels; three patients became hypotensive. Myelosuppression occurred in all patients, including seven without bone marrow infiltration. Transient rises in alkaline phosphatase and transaminases (SGOT) were observed in patients receiving daily doses greater than 30 X 10(6) U/m2. Dose-limiting central nervous system toxicity, hyperkalaemia, and hypocalcaemia were encountered at 200 X 10(6) U/m2. In six patients with acute leukaemia there was a fall in the number of circulating leukaemic blasts and in one patient with acute myelogenous leukaemia (AML) the degree of bone marrow infiltration decreased from 99% to less than 5% with cellularity returning to normal. Serum levels of IFN above 1,000 U/ml were achieved with daily doses above 30 X 10(6) U/m2 given by IVI. The maximum safely tolerated daily dose, 100 X 10(6) U/m2 administered for 7 days, is appreciably higher than that used in most previous studies, although even at this level considerable toxicity may be encountered.

Aziridinylbenzoquinone (AZQ: NSC-182986), is a quinone derivative which has been shown to have activity in implanted murine tumor systems. Toxicity in small and large animals included hypothermia, diarrhea, anorexia, emesis, weight loss, and gastrointestinal bleeding. In addition, there was myelosuppression and elevated liver function tests. In a phase I study at the Mayo Clinic, dose-limiting toxicity was myelosuppression. Patients with prior radiation therapy or prior chemotherapy were more sensitive to this toxicity. A dose schedule of 27.5 mg/m2 q4 weeks was recommended for patients who had had no previous chemotherapy and 22.5 mg/m2 for previously treated patients or for patients who had had extensive prior radiation therapy. The objective of this study was to determine therapeutic activity for AZQ in patients with advanced colorectal adenocarcinoma.

Human fibroblast interferon(HFIF) was used in 26 patients with various malignant diseases, most of whom had previous chemotherapy. The dosages used were 3 X 10(6) IU or 6 X 10(6) IU of HFIF i. v. daily. Out of 24 evaluable patients, there were 2 partial remissions (CLL 1 and multiple myeloma 1), and 7 stable diseases (multiple myeloma 2, stomach cancer 2, non-Hodgkin's lymphoma 1, CLL 1 and malignant melanoma 1). The majority of the patients experienced fever exceeding 38 degrees C and chills, which became uncommon within several days of treatment. Other side effects included myelosuppression, general malaise, anorexia, hepatic dysfunction and renal dysfunction, which were mild and tolerable.

Twenty-seven patients with measurable or evaluable, regionally advanced or metastatic head and neck cancer were given a combination of cyclophosphamide (C), Adriamycin (A), and cis-diamminedichloroplatinum (II) (P). Most patients had received extensive prior surgery and/or radiation therapy. Among 25 evaluable patients, the overall response rate was 64% (16/25) with 3/25 complete responders and 13/25 partial responders. The median survival for the entire group of 25 patients and the median response duration for the subset of 16 patients experiencing tumor regression were 8.1 and 7.0 months, respectively. Responders lived significantly longer than nonresponders (11 months vs. six months, P less than 0.01). According to covariate analysis, the difference seems to reflect the influence of response to treatment and not other confounding variables. Almost all patients experienced anorexia, nausea, vomiting, and a pervasive feeling of ill-health. In fact, six patients declined further treatment and five of these had objective tumor regressions. Recurrent disease was detected three months following discontinuation of chemotherapy in four of these five patients and seven months later in the fifth. Myelosuppression was clinically acceptable and there was in this dosage and schedule no evidence of hepatic or renal impairment. Although the CAP regimen has substantial antitumor activity, the program is clinically rigorous and should remain an investigational treatment modality at the present time.

The antitumor effect of thymidine has been demonstrated in patients with leukemia and lymphoma. This report summarizes the treatment of three patients with mycosis fungoides, a chronic T-cell lymphoma. Four courses of thymidine (75 g/m2/day) were administered by continuous infusion for 4-7 days. Steady-state serum thymidine levels were in the range of 1-3 mM. Associated toxicities were minimal and consisted of milk headache and anorexia. Myelosuppression was manifested by transient declines in the peripheral leukocyte count. One patient had extensive clearing of diffuse erythematous plaques on the trunk and extremities that persisted for over one month. A second patient had partial clearing of plaques that persisted for two weeks following therapy and a third patient had a minimal response with 25% reduction in lymphadenopathy and noduloulcerative lesions. These responses indicate the effectiveness of thymidine as a single agent in the treatment of mycosis fungoides.

High-dose thymidine (dThd) was given to 12 patients with advanced hematological and solid tumors. The dose schedule used was 75 g/sq m/day, given i.v. continuously for 5 days or more. Myelosuppression, especially leukopenia, was the dose-limiting toxicity. Nonhematological toxicities affected the gastrointestinal tract (nausea, vomiting, anorexia, diarrhea, and indigestion) and the central nervous system (somnolence, headache, visual illusions, and memory impairment). Patients who had received cumulative doses of dThd developed alopecia. Thymine crystals were noted in the urine after refrigeration. Tumor regression (less than partial remission) occurred in one patient with melanoma. Three of four patients with acute leukemia had a fall in peripheral white blood cell counts and blasts but no marrow improvement. Four patients with adenocarcinoma (three colon, one unknown primary) had stable disease. Pharmacokinetic studies revealed that, at a dThd dose of 75 g/sq m/day, millimolar concentrations of dThd and thymine can be achieved in the plasma. The half-life of dThd was approximately 100 min. One-third of the plasma concentrations was measurable in the cerebrospinal fluid. dThd was mainly excreted by the kidneys.
