The clinical and immune modulatory effects of interleukin-2 (IL-2) and interferon (INF) alfa-2a were examined in a phase II study in patients with metastatic renal cell carcinoma (six patients) and melanoma (eight patients). Treatment consisted in IL-2 3 MU/m2 continuous infusion days 1-4 and INF alfa-2a 6 MU/m2 subcutaneously day 1 and 4, both given on alternate weeks. Tumour response was assessed after four cycles of treatment or earlier, if necessary. Patients with stable disease or response were to be continued for another nine cycles or up to disease progression. The 14 patients received a total of 60 cycles of treatment. Major toxicities (WHO Grade III/IV) were fever, capillary leak syndrome with hypotension, nausea and vomiting, erythema with pruritus, leuco- and thrombopenia and sepsis with staphylococcus aureus. Five of 14 patients (36%) developed a self limiting autoimmune thyroiditis with HLA-DR expression on thyrocytes. Long term treatment toxicity was moderate with an average weight loss of 5% and an average fall in Karnofsky index of 10% compared to baseline. No responses were seen in renal cell carcinoma, two patients with melanoma had a partial and two a minor response with a duration of 1-7 months. Serial measurements of immune modulatory parameters showed a functional response to treatment with an increase of NK- and LAK-activity during the first two cycles, followed by a plateau and decrease during the third and fourth cycles. These findings were paralleled by a successive decline in treatment induced INF gamma response. These findings suggest, that alternative weekly treatment with IL-2 and INF alfa-2a results in an exhaustion of lytic capacity of NK- and LAK-cells and an attenuation of secondary cytokine release.

Our group and others have conducted phase II trials of high-dose interleukin-2 (IL-2) or IL-2 with the adoptive transfer of in vitro activated lymphocytes in patients with advanced malignancies. Although durable complete and partial responses were seen in patients with renal cell carcinoma and metastatic melanoma, overall response rates were low and toxicity was substantial. In preclinical models, the combination of IL-2 and interferon-alpha has synergistic antitumor activity. Based on these data, and our prior experience with high-dose IL-2 (Cetus), we conducted a trial to determine the maximum tolerated dose of IL-2 (0.4, 0.8, and 1.2 mg/m2) administered together with a fixed dose of interferon-alpha 2b (3 x 10(6) u/m2) intravenously every 8 h on days 1-5 and 15-19. Patients were monitored in the intensive care unit and given pressor support for hypotension as needed. Twenty-four patients were entered (6, 10, and 8 at each IL-2 dose, respectively; 14 renal cell carcinoma, 7 melanoma, 2 colon, and 1 hepatoma). The median age was 56 years, the male to female ratio was 19:5, and performance status was 0 or 1 (Eastern Cooperative Oncology Group) in all patients. Toxicity was similar at all dose levels, but the onset was earlier in the treatment course as the dose of IL-2 was escalated in successive cohorts; therefore, more doses were withheld at the higher dose levels. The major toxicities resulting in the interruption or stopping of treatment were hypotension requiring pressors, dyspnea, and neurotoxicity. Grade 1 or 2 fever, nausea and vomiting, fatigue, and cutaneous reactions were common at all dose levels.(ABSTRACT TRUNCATED AT 250 WORDS)

Trimetrexate glucuronate, a nonclassical antifolate, was administered to 14 patients with recurrent and progressive metastatic malignant melanoma. Thirteen patients were evaluable for response and toxicity. Five patients had received prior treatment consisting of immunotherapy (one patient), immunotherapy plus radiotherapy (one patient), radiotherapy (one patient), chemotherapy (one patient), or radiotherapy and chemotherapy (one patient). The starting dose of trimetrexate was 8 mg/m2 given as an intravenous bolus daily for 5 consecutive days of a 21-day cycle. Subsequent cycles of therapy were escalated by 25% based on individual patient tolerance. A median of two courses of trimetrexate was administered (range 1-4). No patient demonstrated a measurable objective response to this treatment regimen. Trimetrexate was well-tolerated; toxicity was mild and consisted primarily of myelosuppression or nausea and vomiting. At the dose level and schedule used in this study, trimetrexate was not effective for the treatment of disseminated malignant melanoma.

A total of 38 patients with metastatic melanoma received monthly chemotherapy with cisplatin at a dose of 200 mg/m2, per cycle; 14 received 20 mg/m2 cisplatin i.v. on days 1-5 and 24 were given 100 mg/m2 i.v. on days 1 and 8. Objective responses were seen in 2/14 treated on days 1-5 and in 5 of 22 evaluable subjects receiving cisplatin on days 1 and 8, for an overall response rate of 22%. The median survival of all patients was 6 months, with no significant difference observed between the two schedules. Severe neurotoxicity and myelosuppression were more common in patients treated on days 1-5. Two patients treated in this manner were bedridden due to neurotoxicity and four developed grade 4 leukopenia after the first cycle of chemotherapy. Only one patient treated with the divided-dose schedule became leukopenic during the first cycle, and none of the patients were debilitated by neurotoxicity. Thrombocytopenia was statistically more severe. Nausea and vomiting, fatigue, ototoxicity, and paresthesia were seen with equal frequency. Very high doses of cisplatin can be delivered with acceptable toxicity using a divided-dose schedule. As the response rate on this schedule appeared to be comparable with that achieved on the more toxic consecutive 5-day schedule, the former deserves to be tested in diseases known to show a dose response to cisplatin. However, in melanoma, administration of 200 mg/m2 per course did not appear to be associated with a markedly improved response rate, compared with cisplatin alone at "standard" doses.

Recombinant interleukin-2 (rIL-2; EuroCetus, Amsterdam, Netherlands) was studied in an outpatient phase II trial in 14 patients with progressive metastatic renal carcinoma, malignant melanoma, and colorectal cancer. Escalating doses of rIL-2 were administered as subcutaneous bolus every 12 hours, starting at 0.3 million U/m2/d. A 100% dose increase occurred at weekly intervals, up to a maximum of 2.4 million U/m2/d. Responding patients or patients with stable disease after 4 weeks of rIL-2 (n = 9) were continued on maintenance therapy at 1.8 million U/m2 of rIL-2 administered once weekly. After 12 weeks of therapy, one renal cell cancer patient had a partial regression in lung metastases. Bolus injection of rIL-2 (1.2 million U/m2) resulted in peak serum levels of 25 to 30 U/ml. Toxicity of this regimen was moderate, with local inflammation at the injection sites, grade I-II (World Health Organization) malaise, nausea and/or vomiting, and fevers in 70% to 100% of patients treated. Thyroid dysfunction was observed in 10 patients receiving subcutaneous rIL-2; four of these patients had laboratory evidence of hyperthyroidism, and one had hypothyroidism. rIL-2-induced toxicity reversed spontaneously after cessation of treatment. In all patients receiving rIL-2, a dose-dependent increase in peripheral blood lymphocyte and eosinophil counts was noted, with a mean of 2.6 and 3.8 x 1,000/microliters after 4 weeks of therapy; mean lymphocyte and eosinophil counts were measured at 2.0 and 2.4 x 1,000/microliters in patients who received prior high-dose chemotherapy, compared with 3.2 and 5.1 x 1,000/microliters in those who did not.(ABSTRACT TRUNCATED AT 250 WORDS)

2-Amino-5-bromo-6-phenyl-4(3H)-pyrimidinone (ABPP) was given to 59 patients in a Phase I study. The agent was selected because it is an interferon inducer and an immunotherapeutic agent in animal tumor models. The study was conducted in two phases. In the first phase, the drug was administered as a single oral dose of 25-2,000 mg/m2. In the second part, the highest tolerated dose reached during part one was used as the initial dose in a multiple-dose scheme of treatment. Patients were treated weekly. The dose was escalated each week, starting with a dose of 2 g/m2 and escalating to 3, 4, and 5 g/m2. No cardiac, hematologic, hepatic, or renal toxicity was observed. The most common toxicity was nausea and vomiting, which occurred in 18% of the patients; others were headache (8%), abdominal pain (8%), and diarrhea (6%). No consistent induction of interferon and no major modification of host defense parameters occurred. One patient with malignant melanoma showed evidence of tumor regression. Pharmacologic studies demonstrated a significant decrease in the bioavailability of the drug as it was administered in this study. Further studies of ABPP with a preparation that has good availability are indicated to determine the potential antitumor activity of this agent or this class of agents in humans.

The Early Clinical Trials Cooperative Group of the EORTC conducted several phase II studies with a pyrimidine analogue of deoxycytidine, 5-aza-2'-deoxycytidine (DAC). The drug was given as three consecutive 1 h i.v. infusions of 75 mg/m2, separated by intervals of 7 h; courses were repeated every 5 weeks. A total of 101 eligible patients were studied: 42 with colo-rectal adenocarcinoma, 27 with squamous cell carcinoma of the head and neck, 18 with malignant melanoma and 14 with renal cell carcinoma. Drug-induced toxicities consisted of moderate myelosuppression, and nausea and vomiting. One single partial remission was seen in a patient with malignant melanoma. DAC given in this dose and schedule is devoid of antitumour activity in adult patients with these refractory types of carcinomas.

From January 1985 to December 1987, 17 patients with advanced malignant melanoma were treated with the polychemotherapy regimen BELD (bleomycin, 15 mg subcutaneously on day 1 and 4, vindesine 3 mg/m2 intravenously on day 1 and 5, CCNU 80 mg/m2 orally on day 1 and DTIC 200 mg/m2 intravenously on day 1 through 5) proposed as effective (CR + PR 45%) and tolerable. All patients were evaluable for toxicity and 14/17 also for response after 2 BELD cycles (total n. of cycles was 54). Criteria for response were just the same as those used by Young et al. A complete remission and a partial remission (2/14) have been observed at lymph nodal level, the unique sites of the disease in these two patients. Remission lasted 6 and 4 months, respectively. Two other patients showed a minimal response of 2 and 3 months duration (lymphonodal and cutis, respectively); 9 patients had stabilized disease of 5 months median duration. One case of progression of disease was observed. However, toxicity was relevant because of 2 early deaths after the first cycle, most probably therapy related, nausea and vomiting (82%), leukopenia (17%) and muscle rigors (11%).

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)

Carbetimer, a low molecular weight polymer derived from ethylene and maleic anhydride, belongs to a class of chemical compounds different from previously available anticancer agents. It has shown moderate antitumor activity against the Madison 109, Lewis lung, colon 26 and M5076 ovarian carcinomas. In the human tumor stem cell assay, antitumor activity was seen against carcinomas of the breast, ovary, lung, colon and kidney. A total of 26 patients with solid tumors were entered into this trial; carbetimer was given on 5 consecutive days as a 1-2-h intravenous infusion. The dose was escalated from 1.08 to 11 g/m2/day. The drug did not induce the usual side-effects of chemotherapy: leukopenia, thrombocytopenia, alopecia and mucositis were minimal or totally absent. Gastrointestinal toxicity was limited to mild to moderate nausea and vomiting; these were observed at all dose levels and required antimetics in only two patients. The major side-effects of carbetimer consisted of hypercalcemia and neurotoxicity. Hypercalcemia was dose- and treatment duration-dependent. The precise mechanism of hypercalcemia is presently under investigation, but remains unclear. Neurotoxicity was observed only after prolonged therapy; two patients, who received cumulative doses higher than 250 g/m2, developed a peripheral neuropathy with paresthesia, decrease in sensory perception and motor weakness. One patient recovered completely; the other patient improved slightly before developing fatal brain metastases. Two patients with malignant melanoma exhibited major antitumor response; both were previously treated; after excellent partial responses to carbetimer, both were operated on and one is presently disease-free 2 1/2 years after completion of therapy with carbetimer. In conclusion, carbetimer is a new compound with an unusual pattern of side-effects and interesting antitumor activity against malignant melanoma. Its antitumor activity is presently being investigated in phase II trials.
