A phase II trial of intermittent high-dose recombinant interleukin-2 (rIL-2) was initiated to evaluate the response rate, remission duration, and toxic effects in patients with measurable metastatic renal cell carcinoma. The rIL-2 was administered as a bolus intravenous infusion at a dose level of 10.0 x 10(6) U/m2 three times weekly, preceded by indomethacin (50 mg orally). Dose reductions of rIL-2 for hypotension and other grade 3 or 4 toxic effects were permitted. Forty-four patients were entered and 41 were eligible. Previous treatment included nephrectomy (23 patients), radiation therapy (seven), and hormone therapy (three). Most toxic effects observed were moderate and included nausea, vomiting, anorexia (85%); hypotension (85%); fever, chills (78%); central nervous system changes (24%); myelosuppression (27%); and creatinine elevation (15%). Four instances of grade 4 toxicity were observed and included nausea, vomiting with dehydration; hypotension; and myocardial infarction. Thirty patients (73%) required dose adjustments because of toxicity. Five responses (12%) were seen, which included one complete and four partial. Sites of response included lung, liver, and soft tissue; the duration of response ranged from 2 to 20+ months. These results demonstrate that this schedule of rIL-2 can be administered in an outpatient setting, and can produce tumor regression in patients with metastatic renal cell carcinoma, including durable complete responses.

Seventeen patients with advanced uroepithelial cancer were treated with M-VAC regimen. Out of 17 patients, 10 were evaluable but 7 were not. Evaluable 10 patients comprised 7 males and 3 females ranging in age from 50 to 83 (median 69.5). The number of performed cycle ranged from 1 to 3 and the performance status was from 0 to 2. Complete response (CR) was observed in 2, partial response (PR) in 4 and no change (NC) in 4 out of 10 patients. The efficacy rate was 60%. Every site of the tumor responded well and CR was observed, in particular, in nodal and pulmonary metastasis. One of 2 CR patients relapsed and died. One of 4 PR patients died of cancer, 2 are alive with regrowing tumors and the other is alive without disease after surgical removal of all residual tumors. The same regimen was carried out again to 2 patients with regrowing tumors, but no response was observed. As to drug toxicity in total 31 cycles (17 patients), gastrointestinal disturbances, anorexia and alopecia were reversible but hematological toxicity was serious and 3 of 17 (17.6%) died of severe bone marrow suppression. M-VAC is an effective regimen for advanced uroepithelial cancer, but bone marrow suppression was serious. Therefore, special attention should be paid to myelosuppression.

A prospective chemotherapeutic trial using combinations of three drugs consisting of three different protocols was performed in 24 patients with advanced transitional-cell carcinoma of the urothelial tract between April 1981 and August 1986. All patients had histologically proven transitional-cell carcinoma and bidimensionally measurable lesions. The protocol I (PPA) was a 5-day course of treatment with 20 mg/m2 cis-platinum and 5 mg/m2 peplomycin (a derivative of bleomycin) on days 1-5, and 25 mg/m2 adriamycin on day 1. Protocol II (CFMit) was a 10-day course with 3 mg/m2 mitomycin-C and 300 mg/m2 cyclophosphamide on day 1, and 180 mg/m2 5-fluorouracil on days 1-10. Protocol III (PAM) was a 1-day course comprising 60 mg/m2 cis-platinum, 30 mg/m2 adriamycin, and 40 mg/m2 methotrexate. In protocols I and III, the drugs were administered every 4-5 weeks, while in protocol II, the drugs were administered continuously without any interval. Of the 9 patients who received 1 to 5 PPA courses, only 3 patients showed a minor response. In the 10 patients who received 4 to 44 CFMit courses, 3 (33%) achieved partial remission for 1.5-22 months, and 3 had a minor response. Of the 5 patients receiving 3 to 7 PAM courses, 1 patient achieved partial remission for 5 months, and 1 had a minor response. Myelosuppression, nausea, vomiting, and anorexia were frequently observed in each protocol. Loss of hair was often observed in protocols I and III. Stomatitis and diarrhea were observed in protocol II. Three patients in protocol I, 4 patients in protocol II, and 1 patient in protocol III were unable to tolerate more courses of the regimen due to the severe side effects.

The effects and toxicities of interferon alfa are described, and the role of the pharmacist in making decisions and providing education about biologic response modifiers (BRMs) is discussed. Interferons have both direct antitumor activity and extensive effects on the immune system. Two recombinant interferon alfa products--interferon alfa-2a and interferon alfa-2b are available commercially. Indications in FDA-approved labeling for interferon alfa include the treatment of hairy-cell leukemia, acquired immunodeficiency syndrome-related Kaposi's sarcoma, and genital warts; however, it also is being used successfully against early chronic myelogenous leukemia, low-grade non-Hodgkin's lymphoma, cutaneous T-cell lymphoma, and previously untreated multiple myeloma. Other malignancies that respond to treatment with interferon alfa are malignant melanoma, ovarian carcinoma, and renal cell carcinoma. The toxic pattern of interferon alfa consists of flu-like symptoms, which are seen at all doses, on all schedules, and in virtually all patients. After repeated dosing, the chronic toxicities of anorexia, weight loss, and malaise and fatigue may develop. Myelosuppression, central nervous system toxicity, increased hepatic enzyme concentrations, nausea and vomiting, and cardiovascular toxicity also are possible. Serum neutralizing antibodies may be formed during therapy; this phenomenon may affect the clinical outcome. Numerous BRMs are being investigated for clinical use, and pharmacists must become conversant in the issues that surround these agents. Areas in which pharmacist involvement and knowledge are important include overall cost, product similarities and differences, dosing and scheduling, drug delivery systems, ways to minimize waste, adverse effects and their management, drug interactions, storage requirements, differences in production and purification techniques among manufacturers, and education of patients and staff.(ABSTRACT TRUNCATED AT 250 WORDS)

Based on the in vitro and in vivo data suggesting synergistic cytolysis by the combination of 5-fluorouracil and interferon-gamma against a variety of malignant cell lines including a human colon carcinoma cell line (HT-29), we initiated studies in patients with advanced colon or rectal carcinoma. Forty-six patients received 5-fluorouracil as an intravenous injection on days 1-5 and recombinant human interferon-gamma as an intramuscular injection on days 1-14, followed by a rest period of 14 days; courses were repeated every 28 days. In the phase I study, cohorts of two patients received a stepwise dose level increase to achieve the maximum tolerated dose (MTD), at which a total of six patients were studied. The dose levels constituting the MTD were as follows: 5-fluorouracil (500 g/m2/day) and recombinant gamma-interferon (0.5 mg/m2/day). Four patients achieved a partial response in the phase I study. In the phase II study, 30 patients received therapy at the MTD. Among 29 evaluable patients in the phase II study, two patients achieved a partial response. Common toxicities included malaise, fever, anorexia, nausea and vomiting, and diarrhea. Transient severe myelosuppression was common but did not result in significant morbidity. Our data suggest that the combination of 5-fluorouracil and recombinant gamma-interferon did not have the same antitumor effect in patients as it had in the preclinical experiments.

In this phase II trial, 105 eligible patients with no prior chemotherapy and advanced sarcoma received doxorubicin, ifosfamide, and dacarbazine (DTIC) with mesna uroprotection (MAID). Starting doses of these drugs were 60, 7,500, and 900 mg/m2 divided over 72 hours by continuous infusion, respectively. Mesna was given for 84 to 96 hours at 2,500 mg/m2/d. Myelosuppression was dose limiting, causing the only toxic death (sepsis). Nonhematologic toxicity consisted predominantly of anorexia and vomiting. Severe mucositis, macroscopic hematuria, renal tubular acidosis, renal failure, and CNS toxicity occurred in less than 5% of cycles. No cardiotoxicity was detected. The overall response rate (10% complete response [CR]) was 47% (95% confidence intervals, 5% to 18% and 37% to 57%, respectively). Most responses (approximately 70%) were observed within two cycles. Median times to progression were 10 and 9 months, respectively. Histologic high tumor grade, lesions less than 5 cm, and less than 1 year from diagnosis to study entry correlated with the probability of response. The median survival was 16 months. Time from diagnosis to study entry, performance status, and extent of disease, but not histologic grade, correlated with survival. Following CR, two patients remain disease-free at 32 and 16 months. Of the 15 additional patients rendered disease-free with surgery, two remain disease-free at 30 and 18 months with no further therapy. While most relapses occurred in sites of prior involvement, death from CNS metastases occurred in 11 of the 80 patients with high-grade sarcomas, of whom seven were still responding systematically (three complete responders). Because of its substantial response in this phase II trial, the MAID regimen is being compared with doxorubicin and DTIC alone in advanced sarcomas and to observation in the adjuvant treatment of high-grade sarcomas in randomized trials.

Based on the demonstration of in vitro and in vivo synergy between cytosine arabinoside (Ara-C) and cis-diamminedichloroplatinum (CDDP), we designed a Phase II trial of Ara-C plus CDDP for patients with advanced squamous cancers of the head and neck and esophagus. Sixteen patients were treated on a unique schedule of continuous-infusion Ara-C, 30 mg/m2/day over 72 h, plus CDDP, 30 mg/m2/day at hours 12, 36, and 60 of the Ara-C infusion. The objective response rate was 38% (95% confidence limits 14-62%), with two patients achieving complete clinical and radiographic response (9 and 27+ months duration) and four partial responses (median duration 4 months, range 1-7 months). There was no CDDP-related nephro- or neurotoxicities, but a flu-like syndrome of anorexia and asthenia was common. Myelosuppression was the dose-limiting toxicity, necessitating Ara-C dose adjustments in 11 cycles of therapy and leading to fatal sepsis in one patient. We conclude that the activity of this combination, though comparable to that of other CDDP-containing regimens, offers no significant therapeutic advantage, and given the excessive hematologic toxicity, should not be investigated further.

Thirty-one patients with metastatic breast carcinoma refractory to standard hormonal and chemotherapy were treated with cisplatin 100 mg/m2 per course and etoposide 300 mg/m2 per course divided over 5 days. Courses were repeated at 3-6-week intervals, depending on the speed of recovery from myelosuppression. Of 29 evaluable patients, three had complete responses, eight had partial responses, eight had stable disease, and 10 had progressive disease. Nausea, emesis, anorexia, weakness, and easy fatigability were common but tolerable side effects. Myelosuppression was frequent and occasionally profound but there were no deaths from hemorrhage or infection. No significant renal toxicity was encountered. The combination of cisplatin and etoposide has sufficient antitumor activity with acceptable toxicity in heavily pretreated patients to justify its further study in breast cancer.

Lonidamine is an indazole carboxylic acid that has been shown to be synergistic with radiotherapy (RT) in tissue culture and animal models. Clinical experience has shown that lonidamine is well-tolerated, and appears to potentiate the activity of conventional chemotherapy in the treatment of brain metastases. A prospective randomized trial was undertaken to evaluate the use of lonidamine in combination with RT in the treatment of brain metastases. All patients received 3000 cGy of whole brain radiotherapy (WBRT). Fifty eight patients were enrolled; 31 received lonidamine plus WBRT and 27 received WBRT alone. There was no significant difference in response rate or survival between the treatment groups. Lonidamine blood levels were measured in 30 of the 31 patients who received the drug, and were therapeutic (greater than or equal to 15 micrograms/ml) in 50%. Survival and response rate were unaffected by the presence or absence of a therapeutic lonidamine level. The most common side-effects of lonidamine were myalgia, testicular pain, anorexia, and ototoxicity; however, only 2 patients had to discontinue the drug because of intolerable myalgias. No serious organ toxicity or myelosuppression was observed.

Thirteen patients with hematological neoplasms were treated with Bestrabucil (100 mg/day po, total dose 700-9,900 mg), which is the benzoate of an estradiol-chlorambucil conjugate. The diseases from which they suffered consisted of T-cell leukemia (3), lymphoma (3), myeloma (5) and essential thrombocytosis (2). Although this drug was less effective against myeloma, the other diseases were more or less relieved with this medication. That is, Bestrabucil was effective in all three patients with T-cell leukemia, both with essential thrombocytosis and two of the three with lymphoma. It is most interesting that adult T-cell leukemia (ATL) cells decreased remarkably with Bestrabucil, along with the disappearance of several symptoms (bone pain, hypercalcemia etc.). The main side effects during this medication were mammary pain (eight of 13 patients, 62%), anorexia (five of 13 patients, 39%) and loss of libido (three of 13 patients, 23%), but neither severe myelosuppression nor hepatorenal dysfunction was induced.
