Lonidamine revealed synergistic effects with anthracyclines and alkylating agents in experimental investigations. It differs from conventional cytostatics by acting on the cell energy metabolism and also lacks their typical side effects; therefore it may be valuable to be combined with established chemotherapeutic regimens. Because in unselected patients the results of randomized studies may be influenced by differences in type and combination of prognostic factors, we defined strict entry criteria: no previous systemic palliative treatment, disease-free interval less than or equal to 2 years, measurable visceral metastases, number of tumor sites less than or equal to 2, no brain or bone metastases, World Health Organization performance status less than or equal to 2, age less than or equal to 55. In an ongoing rate, remission duration, time to treatment failure, and survival time in patients treated with vindesin 3 mg/m2 plus epirubicin 100 mg/m2 plus cyclophosphamide 600 mg/m2 (day 1, intravenous, repeated every 3 weeks) +/- lonidamine 600 mg/day orally. Eight of 12 patients achieved an objective remission (complete response 4, partial response 4), 1 patients had a stable disease, 2 patients experienced tumor progression; 1 patient is not yet evaluable for response. In spite of the intensity of the therapy no treatment interval prolongation was necessary. Main toxicities were myelosuppression, nausea, emesis, alopecia, and in patients treated with lonidamine, mild myalgia. The addition of lonidamine to polychemotherapy did not affect myelosuppression. Differences in remission rates or remission duration due to lonidamine could not yet be demonstrated.

One hundred twenty-nine dogs with histologically confirmed malignant tumors were used in a prospective study to determine the toxicity of the new dihydroxyquinone derivative of anthracene, mitoxantrone, which was administered IV at 21-day intervals at dosages ranging from 2.5 to 5 mg/m2 body surface area. Each dog was evaluated for signs of toxicosis for 3 weeks after each dose was administered or until the dog died, whichever came first. The number of dogs in each evaluation period were as follows: 1 dose (n = 129), 2 doses (n = 82), 3 doses (n = 43), 4 doses (n = 26), 5 doses (n = 19), 6 doses (n = 9), 7 doses (n = 6), 8 doses (n = 5), 9 doses (n = 3), and 10 doses (n = 1). The most common signs of toxicosis were vomiting, diarrhea, anorexia, and sepsis secondary to myelosuppression. None of the dogs died of complications resulting from mitoxantrone treatment. Dogs with signs of toxicosis during the 21-day interval from administration of the first dose of mitoxantrone were 95 times (P = 0.003) more likely to develop signs of toxicosis during the 21-day interval from the second dose of mitoxantrone. Similarly, dogs that developed signs of toxicosis during the 21-day interval from the administration of the second dose were 34 times (P less than 0.001) more likely to develop signs of toxicosis during the 21-day interval from the administration of the third dose. With each 1 mg/m2 increase in mitoxantrone, the odds of developing signs of toxicosis increased by 5.9 fold (P less than 0.001).(ABSTRACT TRUNCATED AT 250 WORDS)

The purpose of this study was to determine the efficacy of 24-hour concomitant infusions of etoposide (100 mg/m2/day, days 1-3) and cisplatin (45 mg/m2/day, days 2-3) in the treatment of patients with recurrent astrocytoma. All 36 patients entered on this trial had histologic proof of astrocytoma with CT scan evidence of tumor progression despite prior radiotherapy and nitrosourea chemotherapy. At initial diagnosis, three patients had low-grade astrocytoma, but 33 (92%) had high-grade astrocytomas. ECOG performance score was 0-1 in 20 patients and 2-3 in 16 patients. The median age of all patients was 45.5 years. Dose-limiting toxicity was myelosuppression with median leukocyte and platelet nadirs of 2,150/mcL and 56,500/mcL respectively. One life-threatening infection occurred, but there were no treatment-related deaths. Vomiting occurred in 78% of patients, but was severe in only 6%. Peripheral neuropathy occurred in 28% but was severe in only 6%. Six patients (17%; 1 CR, 5 REGR) responded to therapy with median time to progression of 6.0 months (range 1.5-17.7 months). Five additional patients (14%) remained stable greater than 6 months and 1 has not progressed at 17.0+ months. Median time to progression and survival in all patients were 2.7 and 5.8 months, respectively. In conclusion, etoposide and cisplatin at this dose and schedule have limited activity in the treatment of recurrent high grade astrocytomas, although durable responses or periods of stability occurred in some patients. Considering the extent of myelosuppression, near maximal doses of the drugs were given.

Treatment options for patients with ovarian cancer who have failed systemic and intraperitoneal (ip) cisplatin-based chemotherapy are limited. We conducted a phase I clinical study of ip thiotepa in patients with refractory ovarian cancer to determine the maximum tolerated dose (MTD). Ten patients were given 39 courses of thiotepa (median number of courses per patient, 3.5; range, 1-10+). All patients had received prior ip cisplatin; 7 also had received iv cisplatin, and 5 had three or more prior regimens. Thiotepa (30-80 mg/m2) was given ip in 2 liters normal saline every 4 weeks. The therapy was well tolerated. There was no vomiting, stomatitis, alopecia, or peritonitis. The dose-limiting toxicity was myelosuppression. With repeated doses, patients had a delayed marrow recovery and required a 1- to 2-week delay in treatment. Six patients had stable disease (duration 2-14+ months; median duration 5 months); 1 patient had a 50% decrease in CA-125 level, and 1 patient with no measurable disease remained clinically disease-free. In summary, ip thiotepa had clinical activity in heavily pretreated patients with refractory ovarian cancer with disease stabilization seen in 6 of 9 evaluable patients and a partial response seen in 1 patient. Myelosuppression was the only toxicity encountered. A dose of 60 mg/m2 ip is recommended for phase II studies.

We undertook a phase I trial using fixed-dose cisplatin, escalating doses of etoposide, and reinfusion of previously obtained autologous bone marrow in 29 relapsed or refractory small cell and non-small-cell lung cancer patients. Median age was 59 years (range of 38-68 years). Three patients had small-cell and 26 patients had non-small-cell lung cancer. Patients received i.v. cisplatin 200 mg/m2 over 5 days and i.v. etoposide 600 mg/m2/day for 3 days (total of 1,800 mg/m2) that was escalated to 800, 1,000, 1,200, 1,400, and 1,600 mg/m2/day for 3 days (total of 2,400-4,800 mg/m2). Cryopreserved autologous bone marrow was thawed and reinfused through a central venous catheter the second day after the completion of chemotherapy. Toxicities included nausea, vomiting, alopecia, high-tone hearing loss, mucositis, diarrhea, renal insufficiency, metabolic acidosis, and severe myelosuppression. The duration of neutropenia (less than 500 neutrophils/microliter) ranged from 5 to 22 days (median of 11 days) and the duration of severe thrombocytopenia (platelets of less than 20,000/microliters untransfused) ranged from 2 to 19 days (median of 9 days). Reversible renal insufficiency (peak serum creatinines of 6.7, 6.6, 4.3, and 3.5 mg/dl) occurred in four patients who completed the therapy. In three patients, death occurred within 4 weeks of chemotherapy and marrow reinfusion. Three complete and 12 partial remissions (range of 1+(-)22+ months, median of 3 months) were observed. No response was noted in eight patients and tumor progression within 1 month of transplant occurred in two patients. The maximally tolerated dose of etoposide was 1,400 mg/m2/day (total of 4,200 mg/m2), since two of three patients developed life-threatening diarrhea at the 1,600 mg/m2/day (total of 4,800 mg/m2) dose. The encouraging antitumor effects of this regimen suggest that this approach may be useful therapy for lung cancer and other tumors sensitive to VP-16 and cisplatin.

Little is known about the in vivo effects of inhibition of the mitochondrial pyrimidine de novo synthesis enzyme dihydroorotic acid dehydrogenase (DHO-DH). In mice a new inhibitor of DHO-DH, Brequinar sodium (DUP-785, NSC 368390) depleted the plasma uridine concentration to 40% within 2 h, followed by a small rebound after 7-9 days. The drug was subsequently evaluated in a Phase I clinical trial, during which it was possible to follow its biochemical effects in 24 patients (27 courses). In addition to the measurement of plasma uridine concentrations, we also measured in lymphocytes of 9 patients (10 courses) the duration of DHO-DH inhibition. Brequinar sodium was administered every 3 weeks as an i.v. infusion at dose levels of 15-2250 mg/m2. The biochemical effects were studied following the first administration of the drug. In sonicated extracts of lymphocytes from 7 healthy volunteers the activity of DHO-DH varied from 2.0 to 3.9 nmol/h per 10(6) cells, while in the lymphocytes of 9 patients obtained immediately before treatment this value was between 0.5 and 4.8 nmol/h per 10(6) cells. Within 15 min of drug administration DHO-DH activity was not detectable and was still low up to 1 week later. Duration of the inhibition appeared to be related to the extent of clinical toxicity, e.g., myelosuppression, nausea, vomiting, diarrhea, and mucositis. Severe lymphopenia was observed in patients receiving Brequinar sodium at the maximum tolerated dose. At dose levels of greater than or equal to 600 mg/m2, uridine depletion (40-85%) was observed between 6 h and 4 days, followed by a rebound of 160-350% after 4-7 days. The extent of the depletion and of the accompanying rebound of uridine levels and the extent and duration of DHO-DH inhibition in the individual patients could be partially associated with drug toxicity in these patients. This is the first report describing biological effects of DHO-DH inhibition in humans in relation to the degree and duration of inhibition of this enzyme.

Methylglyoxal bis-guanylhydrazone (MGBG), a potent inhibitor of polyamine synthesis, has demonstrated single agent activity against a number of tumor types including malignant lymphomas and head and neck, esophageal and non-small cell lung cancers. The growth of small cell lung cancer (SCLC) cell lines can be arrested by polyamine inhibition. Therefore a phase II trial was conducted in twenty-four patients with refractory SCLC. MGBG was administered by intravenous infusion at a dose of 500 mg/m2 per week for four cycles and then every two weeks thereafter. The dose was escalated by 100 mg/m2 every two weeks in the absence of toxicity greater than or equal to grade 2. One patient achieved a partial response of objectively measurable lung disease and supraclavicular adenopathy. Three patients had stable disease. Dose limiting toxicity consisted primarily of mild to moderate nausea, vomiting, stomatitis and/or diarrhea. Myelosuppression was uncommon and rarely dose limiting. We conclude that MGBG in the dose and schedule used does not have significant activity as a single agent in previously treated small cell lung cancer.

A phase II study of the effectiveness and toxicity of carboplatin in the treatment of metastatic or locally advanced endometrial cancer was carried out by the Southwest Oncology Group. Thirty-two patients were registered in the study and 23 were fully evaluable for response and toxicity. Carboplatin was administered in a dose of 400 mg/m2 at 28-day intervals without concomitant hydration if blood counts had recovered sufficiently. There were seven responses (two complete and five partial responses) among the 23 evaluable patients, for an overall response rate of 30%. Four (two of two complete responders and two of five partial responders) of the seven responding patients remain alive at 839+ to 987+ days from the start of therapy. The two complete responders and one of the partial responders had small-volume disease, which may have contributed to their prolonged survival. Myelosuppression was the most prominent toxicity encountered. Seventeen of 27 patients evaluable for toxicity developed platelet counts of less than 75 X 10(3)/muL during therapy, but no hemorrhagic complications were encountered. Leukopenia was less prominent, with only nine of 27 patients developing white blood cell counts of less than 3.0 X 10(3)/microL. No important nephrotoxicity or neurotoxicity was observed. Emesis occurred in ten of 27 patients but was not dose-limiting. No unexpected toxicities were encountered. Carboplatin appears to be an active agent in the treatment of endometrial carcinoma.

Ninety-eight patients with previously-treated advanced soft tissue sarcoma, bone sarcoma, or mesothelioma were randomly assigned to one of two intravenous single-agent treatment regimens, either 6-diazo-5-oxo-l-norleucine (DON; brief infusions of 50 mg/m2/day for 5 consecutive days every 4 weeks) or aclacinomycin-A (ACM-A, as 30-min infusions of 100 mg/m2 or 85 mg/m2, administered every 3 weeks). Of 43 patients who were evaluable for response, survival and toxicity, there were two responses (5%) produced by ACM-A; one in a male with mesothelioma, and one in a female with malignant fibrous histiocytoma. None of the 36 evaluable patients treated with DON developed an objective tumor response. Median survival was 4.8 months in the DON treatment arm, and 6.8 months in the ACM-A treatment arm. No patients on the DON arm experienced lethal or life-threatening toxicities, and severe toxicities resulting from this treatment included nausea and emesis (10%), stomatitis (2%), gastrointestinal toxicity (2%), and anemia (2%). Moderate toxicities included vomiting (24%), hematologic toxicity (24%), neurologic toxicity (7%), diarrhea (7%), mucositis (5%), fever (5%), palpitations (2%), hepatotoxicity (2%), bleeding (2%) and edema (2%). Fifteen percent experienced at least one severe reaction, and 63% experienced at least one moderate or greater toxicity. ACM-A was associated with four cases of life-threatening myelosuppression (7%); severe toxicities included myelosuppression (11%), neurologic toxicity (4%), diarrhea (2%), respiratory toxicity (2%), pain and muscle spasms (2%), edema (2%), and ulceration following extravasation (2%).(ABSTRACT TRUNCATED AT 250 WORDS)

A drug schedule has been devised based on a strategy of G2 blockade followed by prolonged infusion of tubulin-binding agents. The regimen consists of doxorubicin 32 mg/m2 i.v. and cyclophosphamide 320 mg/m2 i.v. on day 1 followed by vinblastine (0.3 to 1.2 mg/m2/day), cisplatin (3 to 12 mg/m2/day), and vincristine (0.04 to 0.16 mg/m2/day) by continuous intravenous infusion on days 5 to 12. Courses are repeated every 28 days. Eighteen patients with advanced solid tumors received 37 courses of chemotherapy in a pilot study to determine safe drug concentrations for the three-drug infusion for 7 days. Dose limiting toxicity was myelosuppression. Patients who received prior mitomycin-C experienced more profound thrombocytopenia than those who did not. Nonhematologic toxicities included mild nausea, vomiting, and transient elevations of serum alkaline phosphatase and serum creatinine. One patient with squamous cell carcinoma of the esophagus who erroneously received vincristine 0.8 mg/m2 instead of 0.08 mg/m2 for 4 1/2 days developed transient myalgia, ileus, and a transient peripheral neuropathy; the patient achieved a sustained complete remission for 15 months and died of unrelated causes. Minor responses and stable disease were seen in two patients with renal cell carcinoma (1 and 2.5 months), three patients with colorectal carcinoma (1.5, 2, and 4 months), and one patient with squamous cell carcinoma of the tongue (2 months). The ViVACCy drug regimen can be given without undue toxicity and may be active in solid tumors.
