Brequinar, DUP 785, is a substituted 4-quinoline carboxylic acid derivative which in preclinical studies has shown broad antitumor activity. It is a novel antimetabolite blocking pyrimidine nucleotide synthesis. In a clinical phase I study, 83 patients were treated on a weekly schedule and 18 patients on a biweekly schedule. The drug was given intravenously as a short infusion. Three patients were entered on each dose level from a starting dose of 6 mg/m2 up to 2600 mg/m2 weekly. The dose ranges on a biweekly schedule were 500-850 mg/m2. There was no dose escalation in individual patients. Pharmacokinetic studies were performed in 19 patients on a weekly schedule and in two patients on a biweekly schedule. A biphasic decay in plasma was observed with a median half life of 10 h (5.1-23.4). The main dose-limiting toxicity was thrombocytopenia. Of non-hematologic side-effects, stomatitis/mucositis occurred frequently. Skin eruptions occurred rarely, but were a major problem when found. All side-effects were fully reversible; there were no signs of cumulative toxicity. Antitumor activity was observed in one patient with a lung metastasis from a bladder cancer and in a patient with an unknown primary tumor. The recommended doses for phase II trials with DUP 785 are: 1500-2000 mg/m2 on a weekly schedule and 500-750 mg/m2 on a biweekly schedule dependent on status before treatment.

A phase II study of Vindesine for esophageal carcinoma was carried out cooperatively by 10 Japanese institutions. Fifty patients were enrolled in the study over a year and ten months. Four patients could not be evaluated because less than 4 weeks had elapsed since their preceding therapy. There were one complete remission and five partial remissions among the 46 remaining patients, a response rate of 13.0%. The patient experiencing the complete remission is still alive more than 24 months after treatment. The main side effects were depilation, anorexia, stomatitis and leukopenia. Thrombocytopenia and elevations of blood urea nitrogen and creatinine were not marked. There was no mortality connected with the administration of Vindesine. It was concluded that Vindesine is useful in the treatment of esophageal carcinoma as a single agent.

Fifty-two non-resectable and recurrent cancer patients with prior treatment, were entered in this study; 1 esophageal, 33 gastric, 1 duodenal, 4 colorectal, 2 pancreatic, 2 bile duct, and 9 breast cancer. The protocol of this therapy was as follows: On day 1, 500 mg/body cyclophosphamide (CPM) was administered by drip infusion, and on day 2, 200 mg/m2 methotrexate (MTX) was infused intravenously for 30 min; immediately after, 500 mg/body 5-fluorouracil (5-FU) was injected by bolus infusion for 5-10 min. On day 3, 24 hours after MTX administration, leucovorin rescue was added. This combination chemotherapy was repeated every two weeks. As a result, 35 of 52 patients were evaluable and the response rate (CR + PR) was investigated; 2/21 (9.5%) for gastric, 2/7 (28.6%) for breast, and 0% for miscellaneous. As complications for side effect, general fatigue, anorexia, nausea, vomiting and stomatitis were observed symptomatically, and leukopenia and thrombocytopenia were recognized in laboratory data as dose limiting factors.

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.

We conducted a phase II trial of deoxycoformycin (pentostatin [DCF]) in chronic lymphocytic leukemia (CLL). Eligibility criteria included age greater than 18 years, Cancer and Leukemia Group B (CALGB) performance status 0 to 2, lymphocyte count greater than or equal to 15,000 cells/microL, international stage B or C disease (multiple lymph nodes involved and/or hemoglobin [Hgb] less than 11 g and/or platelets less than 100,000/microL) and no more than one prior treatment regimen. DCF dose was 4 mg/m2 intravenously (IV) weekly for 3 weeks and then every 2 weeks. There were 39 eligible patients (35 men and four women; median age, 63 years; median time from diagnosis to study entry, 3 years). Of these 39 patients, 31% were stage B and 33% had no prior treatment. Median laboratory values at entry were Hgb 10.5 g, WBC 96,100/microL, and platelets 93,500/microL. Nodal involvement was present in 90%, splenomegaly in 81%, and hepatomegaly in 47%. Patients received a median of nine DCF injections, with a range of four to 26. Three patients were not evaluable for response. Overall, 3% achieved a complete response (CR), 23% a partial response (PR), 28% showed clinical improvement (CI), and 38% had stable disease (SD). Associated toxicities (grade 2 or worse) observed were infections (52%), worsening of thrombocytopenia (26%) or anemia (33%), nausea and vomiting (31%), rash or pruritus (20%), and stomatitis (8%). We conclude that DCF is an active agent in CLL with acceptable toxicity.

We evaluated the role of gallium nitrate infusion in the treatment of metastatic breast cancer. Gallium nitrate was administered at 300 mg/m2/day for 7 days every 3 weeks by continuous infusion concomitantly with oral calcium supplement of 500 mg twice daily and oral hydration. Fifteen patients with refractory metastatic breast cancer received such treatment for a total of 30 courses. Median age was 51, and median performance status (Zubrod scale) was 1. These patients had minimal prior chemotherapy (median 1 regimen). All patients were evaluable for toxicity and 14 for response. Nine patients had one to two metastatic sites, five patients had three to four sites. No major objective response was seen, but one patient had a minor response (10 weeks), and another showed no change in disease (16 weeks). Diverse low-grade toxicities were observed, including nausea and vomiting in 11 patients, anorexia in 11, diarrhea in eight, stomatitis in five, dysgeusia in six, musculoskeletal pain in five, skin rash in seven, partially reversible tinnitus and/or mild hearing loss in four and sensory neuropathy in two. A consistent drop in hemoglobin (median of 3.2 g/dL per patient) necessitated blood transfusion in seven patients. There was no granulocytopenia or thrombocytopenia; however, significant lymphopenia was noted. Reversible, moderate nephrotoxicity occurred in two patients. The hypocalcemic effect was consistent, with a median drop in serum calcium of 1.25 mg/dL per course. There was no hepatic toxicity. While no single toxicity was severe, overall toxicity adversely influenced treatment tolerance. Gallium nitrate by continuous infusion, as given in this study, has no activity in metastatic breast cancer.

Forty-seven adult patients with glioblastoma multiforme (GBM) were treated in a phase I/II study combining continuous intravenous (IV) infusions of iododeoxyuridine (IdUrd) and hyperfractionated radiation therapy. IdUrd was administered as a continuous infusion (24 h/d) for two separate 14-day infusion periods. The dose of IdUrd was escalated from 500 to 1,200 mg/m2/d. The initial wide-field tumor volume was treated to 45 Gy at 1.5 Gy fractions twice daily over 3 weeks. Following a planned 2-week break, a reduced-field boost of 25 Gy was delivered using 1.25 Gy fractions twice daily over 2 weeks (total dose, 70 Gy over 9 weeks). The IdUrd infusion preceded both the wide-field and reduced-field irradiation by 1 week. All treatment was performed on an outpatient basis. Dose-limiting systemic toxicity to the bone marrow (primarily thrombocytopenia) and gastrointestinal (GI) tract (both stomatitis and diarrhea) established the maximum tolerable dose (MTD) at 1,000 mg/m2/d for a 14-day infusion. Significant local toxicity (within the radiation field) was not seen. The kinetics of IdUrd were linear with dose escalation and reached steady-state plasma concentrations of 1.3 to 3.4 mumol/L. The total body clearance of IdUrd was .82 L/min/m2. The primary metabolite, 5-iodouracil (IUra) approached steady state by day 6 of the infusion when plasma levels were 60 times higher than IdUrd. Plasma levels of uracil and thymine, but not thymidine, were elevated throughout the infusion. With a minimum follow-up of 1 year, ten patients remain alive, while 33 patients died of progressive disease, and four patients died of other causes (including one treatment-related death). The median survival for all 47 patient and for the 40 patients receiving the MTD was 45 and 47 weeks, respectively, with 12% and 14% survivals at 24 months. Using a Cox regression analysis, age (less than or equal to 50 years v greater than 50 years) and pretreatment performance status (PS) (Eastern Cooperative Oncology Group [ECOG]-PS 0 to 1 v PS 2 to 3) were independent, statistically significant (P2 less than .05) predictors of survival, with the ECOG status being a better predictor. Patients with a PS 0 to 1 (28 patients) had a median survival of 64 weeks with 21% survival at 24 months, compared with a median survival of 29 weeks and 0% survival at 12 months in the 19 patients with PS 2 to 3. The overall and subgroup survival data are at least comparable to other combined modality treatment approaches in patients with GBM.

Taxol is a unique plant product that promotes in vitro assembly of microtubules. In a phase I trial, adults with advanced solid tumors were given taxol (formulated with cremophor EL and dehydrated alcohol) as a 3-hour iv infusion every 21 days. The total dose administered ranged from 15 to 230 mg/m2 in nine escalation steps. Leukopenia, thrombocytopenia, nausea and vomiting, alopecia, stomatitis, transient rashes, increases in serum triglyceride levels, and hypersensitivity reactions were observed. Hypersensitivity reactions characterized by acute dyspnea, generalized erythema, and hypotension immediately following the initiation of the taxol infusion occurred in three of five patients receiving greater than or equal to 190 mg/m2 (18% of patients overall). No antitumor activity was observed. Hypersensitivity reactions constituted a treatment-limiting toxicity for this preparation of taxol given on this schedule over the dosage range examined. With the severity and unpredictability of the hypersensitivity reactions, further usage of taxol is not indicated with this drug formulation on this administration schedule. Further studies are warranted to uncover ways to permit the safe administration of taxol.

Low-dose continuous infusion 5-fluorouracil (LDCI-FU) was administered to 28 women with advanced breast carcinoma. Daily doses ranged from 175 to 250 mg/m2. The LDCI-FU was delivered continuously until the appearance of toxicity and was reinstituted at a 20% dose reduction after toxicity completely resolved. Patients with a median age of 56 years and a median performance status of 60% (Karnofsky) had been previously treated with combination chemotherapy. Complete responses were observed in two patients with soft tissue metastases. Thirteen patients experienced partial responses with a median duration of response of 4+ months. Partial responses were predominantly observed in soft tissue disease; however, five patients with visceral metastases experienced partial tumor regression. Median survival for the study group was 4+ months. Hormonal receptor status did not predict response to LDCI-FU. Toxicities included stomatitis, ten patients; hand-foot syndrome, eight patients; mild leukopenia, two patients; moderate thrombocytopenia, two patients; diarrhea, three patients; ataxia, three patients. Catheter-related toxicities of sepsis and/or thrombosis occurred in six patients. Because of the demonstrated activity in previously treated patients (53% response rate), LDCI-FU should be investigated in combination chemotherapy regimens in untreated breast cancer patients.

The compatibility and stability at room temperature for up to 7 days of a three-drug admixture of cyclophosphamide, methotrexate, and 5-fluorouracil (5-FU) (CMF) was established permitting the practical delivery of the combination as an infusion in an ambulatory setting. Fourteen patients received 20 courses of CMF administered on a continuous infusion schedule for 14 days of a 28-day cycle. The dose rates were fixed for 5-FU (300 mg/M2/day) and methotrexate (0.75 mg/M2/day). The cyclophosphamide dose was escalated from 25 to 50, 75, and 100 mg/M2/d. Leukopenia and thrombocytopenia were observed in two of five patients receiving the maximal dose of cyclophosphamide. No other toxicities were observed including alopecia, stomatitis or liver function abnormalities. This Phase I trial suggests that the cumulative doses of cyclophosphamide, methotrexate, and 5-FU are comparable to the maximum doses delivered as single agent infusions. Furthermore, when the infusion CMF is compared to the "standard" bolus schedule for CMF, the infusion schedule delivers 116%, 8%, and 350% of the respective three component drugs (cyclophosphamide, methotrexate, and 5-FU).
