The antitumor activity of zeniplatin, a third-generation, water-soluble platinum compound that has shown broad preclinical antitumor activity and no significant nephrotoxicity in phase I trials, was tested in patients with advanced malignant melanoma and advanced renal cancer. Patients who had not previously been treated, except with local limb perfusion and immunotherapy, were given zeniplatin as bolus injections at 125 mg/m2 every 3 weeks. The main hematological toxicity was leukopenia (7/30 patients, WHO grade > or = 3) and the main nonhematological toxicity was nausea and vomiting (21/30 patients, WHO grade > or = 2). Serious nephrotoxicity was observed early in the renal cancer study and, later, also in the melanoma study. Hyperhydration did not prevent the nephrotoxicity, and the studies were stopped after 6 renal cancer patients and 24 malignant melanoma patients had been included. Zeniplatin gave objective responses in 3 of the 21 evaluable malignant melanoma patients [2 complete responses (CRs) in patients with lymph-node metastases lasted 5 and 14 months, respectively; 1 partial response (PR) in a patient with lymph-node and liver metastases lasted 6 months]. In the renal cancer study, only four patients were evaluable for response and none responded. The results show that zeniplatin has some activity (14%) in patients with advanced malignant melanoma, but no conclusion can be drawn regarding the activity of zeniplatin in renal cancer as the number of patients was too low. The main toxicities were leukopenia and nausea and vomiting. Unexpected and serious nephrotoxicity was observed, and for this reason the studies were terminated before the planned number of patients had been included. A possible explanation for the nephrotoxicity may be drug interactions, but no firm conclusion can yet be drawn.

Four years following resection of a Clark's level IV malignant melanoma, a 50-year-old man developed widespred metastatic disease involving the liver, bones, brain, gastrointestinal mucosa, and lungs. One week after whole brain radiation therapy, he was admitted to the hospital for nausea, vomiting, and pain. He was treated with several antiemetic drugs, but it was not until dronabinol was added that the nausea and vomiting stopped. Dronabinol was an effective antiemetic used in combination with prochlorperazine in nausea and vomiting unresponsive to conventional antiemetics.

Twenty-three patients with advanced melanoma were treated with a combination of subcutaneous recombinant human interleukin-2 (IL-2), and recombinant interferon alpha-2a (IFN-alpha) with chemotherapy consisting of four cycles of carboplatin (300 mg/m2, day 1) and vinblastine (6 mg/m2, day 1), every 28 days (CV-IL-IF). IL-2 was given at a dose of 4.5 x 10(6) U twice daily on days 3-6 and days 21-24 of each cycle; IFN-alpha dose was 4.5 x 10(6) U, starting on day 2, thrice weekly. Immunotherapy was intended to continue for 6 months. Of the 23 analyzed patients, 4 (17%) achieved an objective response, including 1 complete and 3 partial responses, in nonvisceral metastatic disease. The median time to progression was 5 months and the median survival from onset of the treatment 6 months (range 1-14 months). Four patients discontinued the treatment, due to nonhaematologic toxicity; 3 for severe weakness and the 4th patient for long-lasting CNS side-effects. Other grade 3-4 toxicities included weight loss (22%), nausea and vomiting (17%) and alopecia (13%). The haematologic toxicity was acceptable. No toxic death was noted. It is concluded that the CV-IL-IF regimen has limited activity and moderate toxicity.

In order to estimate the therapeutic activity and tolerability of immunochemotherapy with recombinant interferon-alpha 2b (rIFN-alpha 2b) plus dacarbazine (DTIC), a study was carried out in 61 patients with cytologically and/or histologically confirmed metastatic malignant melanoma. The treatment regimen was as follows: rIFN-alpha 2b 2 x 10(6) IU intramuscularly on days 1 to 4, and DTIC 800 mg/m2 intravenously on day 5, repeated at 3-week intervals until the progression of the disease or, in the case of a complete response, for up to 6 months. The overall response rate was 28%-12% complete response (CR) and 16% partial response (PR). The median response duration was 10.9 months (CR 11.5 months, PR 9.3 months; P > 0.05). Responses occurred in soft tissue and lung metastases only. The median times to treatment failure for responding and non-responding patients were 10.9 and 3 months, respectively (P < 0.0001), and the median survival durations were 16.5 and 5.8 months, respectively (P < 0.0001). The stratification of the patients into a low-risk group (World Health Organization performance status [WHO PS] < or = 1 and soft tissue or lung metastases) and a high-risk group (WHO PS = 2 or disease localization other than skin, lymph nodes or lung) showed a significant advantage for the first group with respect to the response rate, median time to treatment failure and survival duration. A flu-like syndrome was recorded in 72% of patients, nausea and vomiting in 34%, haematological toxicity in 26%, hepatic toxicity in 5%, and neurotoxicity in 5%. In view of the results obtained in our study and those reported in the literature, IFN plus DTIC immunochemotherapy represents a reasonable treatment option, particularly for patients with soft tissue and lung metastases.

Temozolomide, a methylating imidazotetrazinone, has antitumor activity against gliomas, malignant melanoma, and mycosis fungoides and is presently administered as a 5-day oral schedule every 4 weeks. This Phase I study aimed to determine the maximum tolerated dose of temozolomide administered as a single oral daily dose for a continuous 6- or 7-week period, evaluate the plasma pharmacokinetics on this schedule, and compare total plasma exposure over 7 weeks with the conventional 5-day regimen. Twenty-four patients with varying tumor types (17 of 24 gliomas) received temozolomide. All had clinically evaluable, refractory disease; normal renal, hepatic, and bone marrow function; and WHO performance status < or = 2. Temozolomide was administered at 50 mg/m2/day, increasing by 25 mg/m2/day/cohort until at 100 mg/m2/day grade 4 myelotoxicity forced dose reductions to 85 mg/m2/day, then 75 mg/m2/day. At 75 mg/m2/day the regimen was extended to 7 weeks, allowing the future potential combination with irradiation for primary gliomas. Patient responses (standard Union International Contre Cancer criteria; for gliomas objective response) and toxicity were assessed. Temozolomide plasma pharmacokinetics were determined on day 1 and at the beginning of the final week of administration (n = 5). The most frequent toxicities were myelosuppression and grades 1 and 2 nausea and vomiting. Grade 4 leucopenia and thrombocytopenia occurred in one of four patients receiving 100 mg/m2/day temozolomide and in one of seven patients receiving 85 mg/m2/day. These hematological toxicities did not exceed grade 2 in 10 patients receiving 75 mg/m2/day temozolomide. One of 4 malignant melanoma patients and 7 of 17 glioma patients (41%) demonstrated tumor responses. The overall response rate for this prolonged schedule was 33% (objective response, 7 of 24 patients; partial response, 1 of 24 patients); also, 6 of 17 glioma patients maintained SD. Peak plasma temozolomide concentrations were obtained 30-90 min after oral administration. Elimination in plasma was best described by a monoexponential equation with an elimination half-life of 96 +/- 16 min. No plasma accumulation of temozolomide occurred. Toxicity was greatest in higher dose cohorts, with a resultant maximum tolerated dose of 85 mg/m2/day, whereas lower dose cohorts tolerated the schedule well. The area under the temozolomide plasma versus time curve was noncumulative between the first and last week of the schedule. Temozolomide administration of 75 mg/m2/day over a 7-week period permits a 2.1-fold greater drug exposure/4 weeks in comparison with the 5-day schedule of 200 mg/m2/day repeated every 28 days. The overall response rate was 33% (glioma patients, 41% and a further 25% SD). Temozolomide (75 mg/m2/day) for 7 weeks is the recommended starting dose for further assessment of this schedule.

Interleukin-2 (IL-2) is a potent lymphokine that activates natural killer cells, T cells, and other cells of the immune system. Several distinct recombinant human IL-2 preparations have shown antitumor activity, particularly for renal cell cancer and melanoma. Somewhat distinct immune and clinical effects have been noted when different IL-2 preparations have been tested clinically; however, the regimens and doses used were not identical. To compare these more directly, we have evaluated two clinical recombinant IL-2 preparations in vitro and in vivo using similar regimens and similar IUs of IL-2. We used the Food and Drug Administration-approved, commercially available Chiron IL-2 and the Hoffmann LaRoche (HLR) IL-2 supplied by the National Cancer Institute. Using equivalent IUs of IL-2, we noted quantitative differences in vitro and in vivo in the IL-2 activity of these two preparations. In patients receiving comparable IUs of the two preparations, HLR IL-2 induced the release of more soluble IL-2 receptor alpha into the serum than Chiron IL-2. In addition, more toxicities were noted in patients receiving 1.5 x 10(6) IU of HLR IL-2 than were seen in patients treated with 1.5 x 10(6) or even 4.5 x 10(6) IU of Chiron IL-2. These toxicities included fever, nausea and vomiting, and hepatic toxicity. In vitro proliferative assays using IL-2-dependent human and murine cell lines indicated that the IU of HLR IL-2 was more effective than Chiron IL-2 at inducing tritiated thymidine incorporation. Using flow cytometry, we also found quantitative differences in the ability of these two preparations to bind to IL-2 receptors. These findings indicate that approximately 3-6 IU of Chiron IL-2 are required to induce the same biological effect as 1 IU of HLR IL-2.

In this phase II study we assessed the efficacy of bryostatin-1 (NSC 339555) in metastatic melanoma patients when given intravenously either once a week at a dose of 25 microg/m2 per day over 24 h for 3 weeks or at 40 microg/m2 per day over 72 h every 2 weeks. Treatment courses were repeated every 4 weeks. Patients who had received one prior chemotherapy regimen for advanced melanoma, with or without biotherapy, were randomized to one or the other bryostatin-1 dose schedules until 12 patients were registered to each arm. Because there was one confirmed response among the 12 patients who received the 72 h dose schedule, 25 more patients were added to that arm. No prophylactic medications were given. Objective tumour measurements were used to assess the efficacy of the regimen. The National Cancer Institutes common toxicity criteria were used to grade reactions. In total, 49 patients with metastatic melanoma, none having symptomatic brain metastasis, were studied. Of these, 12 patients received the 24 h bryostatin-1 regimen, while the remaining 37 received the 72 h regimen. One patient receiving the 72 h regimen had a partial response lasting over 7 months. Muscle pain occurred in over 90% of the patients and was the dose-limiting side effect of the 72 h regimen. Grade 3/4 nausea and vomiting were more common on the 24 h regimen than on the 72 h one (35% versus 5% of patients). There was no therapy-related thrombocytopenia. Neutropenia was mild and mainly limited to patients receiving the 72 h regimen. Bryostatin-1 has limited activity against melanoma when given by 72 h intravenous infusion.

We have previously demonstrated that the combination of tamoxifen and cisplatin has activity in patients with metastatic melanoma. In vitro studies have demonstrated that tamoxifen and cisplatin exhibit cytotoxic synergy in human melanoma cells and that this interaction is dependent on a tamoxifen effect. The mechanism of this effect is currently under investigation in in vitro studies. In an attempt to improve the complete response rate of this regimen, we initiated a phase II trial to determine the effect of the use of high dose tamoxifen and weekly cisplatin on the complete response rate, disease-free survival and overall survival. Tamoxifen was started on day 1 initially at a dose of 240 mg/day and continued until the patient was taken off treatment. This dose was subsequently lowered to 200 mg/day. Cisplatin (80 mg/m2) was begun on day 2 and repeated weekly for a total of 3 weeks. During week 4, the patient was not treated with cisplatin but was evaluated for response. If disease stabilization or regression was documented, the patient received a second 3 week cycle of cisplatin and was then re-evaluated for response. Patients with progressive disease at any evaluation were removed from the study. In 28 consecutive patients, the overall response rate was 32% (95% confidence interval 15.88-52.35%). One patient achieved a complete remission that lasted 22 months. All other responses were partial in nature. Toxicity was primarily nausea and vomiting. Two patients developed grade 2 renal toxicity. There were no episodes of deep venous thrombosis. This phase II study demonstrates that this combination has modest activity in patients with metastatic melanoma. However, this study failed to confirm our hypothesis that high dose tamoxifen would increase the complete response rate of this combination. While this combination has activity, the overall response rate is not significantly better that that observed with the original Dartmouth regimen and the toxicity is substantial. We do not recommend this dose and schedule for routine clinical use.

Malignant melanoma is rapidly increasing in the United States. Metastatic disease responds poorly to currently available chemotherapy. Pyrazine diazohydroxide (PZDH) is a new agent inhibiting DNA synthesis that is active in mouse tumor models and human xenografts and lacks cross resistance with multiple standard agents. In this phase II trial, patients with no prior chemotherapy or immunotherapy for metastatic disease and performance status (SWOG) of 0-1, were treated with pyrazine diazohydroxide at a dose of 100 mg/m2/day by i.v. bolus injection over 5-15 minutes for 5 consecutive days every 6 weeks. There were 23 eligible patients entered on this trial with 74% having PS of 0 and 91% having visceral metastases. There were no confirmed anti-tumor responses. The overall response rate is 0% (95% CI 0%-15%). Median overall survival is six months (95% CI 5-8 months). The most common toxicities were hematologic and consisted of lymphopenia, thrombocytopenia, anemia, and leukopenia. Fatigue. and nausea and vomiting were the next most common toxicities. Pyrazine diazohydroxide by this dose and schedule has insufficient activity in the treatment of disseminated malignant melanoma to warrant further investigation.

Yondelis (ET-743) is a novel anticancer agent isolated from the marine ascidian Ecteinascidia turbinata. ET-743 possesses potent antitumour activity and a novel mechanism of action at the level of gene transcription. We conducted two sequential phase I dose escalation and pharmacokinetic studies of ET-743 given as a 1- or a 3-h intravenous (i.v.) infusion. Seventy-two adults with metastatic or advanced solid tumours received ET-743 in escalating doses between 50 and 1100 microg/m(2), initially as a 1-h infusion, and later at doses between 1000 and 1800 microg/m(2) as a 3-h infusion every 3 weeks. The maximum tolerated dose (MTD) of ET-743 was 1100 microg/m(2) for the 1-h infusion schedule and 1800 microg/m(2) when given as a 3-h infusion. Dose-limiting toxicities (DLTs) were fatigue, neutropenia and thrombocytopenia. Transient non-cumulatives grade 3-4 increase in transaminases (not considered DLT) and grades 3-4 nausea and vomiting were frequently observed. Other toxicities (maximum grade 3) included anaemia, increased lactate dehydrogenase (LDH), bilirubin and alkaline phosphatase serum levels, and phlebitis; there were no toxic deaths. One pCR (melanoma), CR (uterine leiomyosarcoma), one PR (colon stromal sarcoma) and a MR (37% tumour shrinkage, gastric stromal sarcoma) were observed. A further 9 patients with colorectal, mesothelioma, bile duct carcinoma and bladder cancer had SD which lasted for six or more treatment cycles. ET-743 pharmacokinetics were linear with the 3-h infusion schedule. The haematological and hepatic toxicities of ET-743 were dose-dependent and not cumulative. Based on the current trial, the recommended dose of ET-743 for phase II studies is 1650 microg/m(2) given as a 3-h infusion.
