Dianhydrogalactitol was given to 28 patients with a variety of advanced solid tumors on a weekly schedule in iv doses ranging from 2 to 80 mg/m2. No significant toxicity was encountered at doses up to 40 mg/m2/week for 4 weeks. At higher doses mild-to-moderate nausea and vomiting and hematologic toxicity were noted. Thrombocytopenia was more common than granulocytopenia and frequently resolved more slowly. No adverse drug-realted effects on liver, renal, coagulation, or cardiac function were seen. Although no patient had significant antitumor response (as strictly defined), objective improvement was noted in two patients, one with hypernephroma and the other with malignant melanoma. for phase II studies, a weekly dose of 70 mg/m2 is recommended for patients with normal hematopoiesis, with reduction by 25% (55 mg/m2) in patients with extensive prior radiation therapy, prior chemotherapy, and/or widespread metastasis to the bone.

CCNU (1-[2-chloroethyl]-3-cyclohexyl-1-nitrosourea, NSC-79037) was used to treat advanced malignancies in 329 evaluable patients. The treatment dosage was 130 mg/m2 for patients with adequate bone marrow reserve and 100 mg/m2 for those with compromised bone marrow. Oral treatment was repeated at 6-week intervals unless hematologic toxicity intervened. There were four complete responses: two in ovarian cancer, one with small cell carcinoma of the lung, and one with melanoma. Tumor response greater than 50% reduction in tumor size occurred in 39 patients (11.9%) while stable disease (no change or decrease or increase of less than 50% in tumor size) was noted in 152 patients (46.2%). Tumor progression occurred in 130 cases. Melanomas and ovarian and lung cancers had the highest response rates. Bone marrow depression was the major side effect of treatment; there was a significant positive correlation between the severity of leukopenia and thrombocytopenia and tumor response to treatment.

An initial clinical phase I trial of inosine dialdehyde has been carried out in 40 patients at dose levels of 30-4000 mg/m2 for 5 days given intravenously (iv) monthly. At 1.5 g/m2, noncumulative dose-related toxicity occurred in all patients which consisted of nausea and vomiting, local pain, alterations in coagulation mechanism, elevated partial thromboplastin time, and positive Coombs' test. No dose-limiting leukopenia, thrombocytopenia, anemia, or bleeding occurred; however, depression of the leukocyte and platelet counts, and decreased hemoglobin value were observed. The dose-limiting toxic effect was renal tubular damage with reversible acute renal failure in one of four patients who received 3000 mg/m2 iv for 5 days. Refractory hypercalcemia was controlled in three of three patients without tumor effect. Responses occurred in patients with seminoma, oat cell carcinoma, and melanoma. A starting dose of 2 g/m2 for 3 days monthly is recommended for phase II trials and a trial in lung carcinoma is now being conducted.

19 patients with advanced malignant melanoma were treated with fotemustine and dacarbazine. Data recorded and available for evaluation in all patients included clinical and histopathological parameters of the primary melanoma, blood chemistry, blood cell count, chest X-ray, ultrasound and bone scan for initial staging of the site of metastases and follow-up during treatment. Dosage was fotemustine 100 mg/m2 and dacarbazine 200 mg/m2 intravenously twice monthly on days 1 and 8, repeated for a maximum of six courses. There were two complete and three partial responses in 5/19 patients (26%), and 8 patients (42%) had stable disease. 6 (32%) patients had no response. Median length of complete and partial responses was 3.9 months, and that of stable disease 4.2 months. The main side-effects were thrombocytopenia in 10 patients (53%) and nausea in 6 (32%); the nausea was easily suppressed by ondasetron. Thus, fotemustine-dacarbazine may be new treatment in advanced melanoma.

ImuVert, a new biological response modifier, was evaluated for toxicity and potential efficacy in patients with advanced cancer. This agent consists of sized, labile, natural membrane vesicles associated with ribosomes derived from Serratia marcescens. ImuVert induces enhanced in vitro macrophage and natural-killer-cell-mediated cytotoxicity, and has demonstrated antitumor activity in palpable animal tumor systems. A group of 39 patients with a variety of tumors, 25 men, 14 women, with a mean performance status (Karnofsky) of 80% and median age of 57 years were entered into this trial. ImuVert was administered subcutaneously weekly for a minimum of 3 weeks. A total of 183 treatments were evaluated. Flu-like systemic toxicities, including fever, chills, nausea, vomiting, diarrhea and hypotension were observed. Erythema, induration and tenderness developed at the injection sites. Myelosuppression, thrombocytopenia, anaphylaxis, rental and hepatic toxicities did not occur. All symptoms resolved within 24 h. Two patients with nodular lymphoma achieved a partial response and two minor responses were seen in patients with glioblastoma and melanoma. On the basis of ImuVert's biological activity, and tolerable toxicity it warrants further clinical investigation.

Recombinant interleukin-2 (IL-2) produces clinical responses in approximately 20% of adult patients with renal cell carcinoma and melanoma, with both high-dose bolus and continuous infusion regimens. Because of the lower toxicity of continuous infusion, we elected to investigate in a Phase I trial a 5-day continuous infusion repeated for three weeks in children with malignancies refractory to standard therapy. Nineteen children with solid tumors and eight children with hematologic malignancies were entered into the study. The maximum tolerated dose was 3 x 10(6) U/m2/day, with dose-limiting toxicities occurring in five of seven patients treated at the 5 x 10(6) U/m2/day dose level. Dose-limiting toxicities included hypotension, hyperbilirubinemia, thrombocytopenia, pulmonary/pleural effusion, and nephrotoxicity. Serum IL-2 levels were detectable at the higher dose levels and were comparable to those observed in adult patients. Hematologic changes at the higher dose levels included rebound lymphocytosis occurring within 48 h of discontinuation of IL-2, eosinophilia, and decreased platelet counts. No objective responses to therapy were seen. We have identified a dose and schedule of administration for IL-2 in pediatric patients that can be given without intensive care unit support. Pediatric Phase II trials examining the anti-tumor activity of IL-2 given by this schedule are in progress.

The recently synthesized nitrosourea, N-[N'-chloro-2-ethyl-N'-nitrosocarbamoyl]-S-methyl cysteamine sulfoxide (Perrimustine), is water soluble and has a high alkylating activity, similar to that of the widely used nitrsoureas BCNU and CCNU, and a low carbamoylating activity. Preclinical studies with a broad spectrum of murine tumors indicate that this new compound may be clinically useful. The maximally efficient dose range (MEDR) in L1210 bearing mice was 45 mg/m2 (subcurative dose) to 67 mg/m2 (subtoxic dose). The present phase I trial used an intrapatient escalation schedule, so that each patient entering the study received a potentially active dose. The first dose injected was 1:100 of the MEDR suboptimal dose to check for anaphylactic sensitivity. Patients were then given increasing doses at increasing time intervals until toxicity was observed. The highest dose was given on day 150-230. The main toxic effect was myelosuppression [five out of the 24 patients evaluated: one grade 4 thrombocytopenia, two grade 3 thrombocytopenia; anemia and leucopenia were milder (grade 1 to 2 on OMS scale)]. Of the 19 patients evaluated for clinical response, one showed response after the 45 mg/m2 dose (disappearance of the cerebral metastasis with persistence of hepatic localizations in a patient with melanoma) and the disease was stabilized in two cases (a pleural mesothelioma and a renal carcinoma with lung metastases) after 26 and 37 weeks, with total cumulative doses per m2 of 232 and 196 mg, respectively.

Resistance to alkylating agents is partly due to the presence of the DNA repair enzyme, termed O6 alkyltransferase (O6AT). Preclinical evidence of the transient restoration of sensitivity of cells resistant to nitrosoureas by pretreatment with a methylating agent, whose role is to deplete cells of O6AT activity and clinical evidence of such a depletion in patients lymphocytes, led us to test the sequential administration of dacarbazine 3 h prior to fotemustine, a chloroethylnitrosourea derivative. 24 patients with measurable advanced melanoma entered the trial and are evaluable. Toxicity was mainly haematological with early neutropenia and/or thrombocytopenia. Clinical activity (33%) was impressive especially on lung metastases with high complete response rate for that site (7/14). Unfortunately, the occurrence of a rapidly fatal pulmonary toxicity precludes further use of the regimen before a plausible explanation for this unexpected toxicity is obtained. Indeed, similar cases have been reported in other trials using the sequential schedule while no lung toxicity was reported in single agent or alternated administrations. Preclinical studies are ongoing to test the hypothesis of a glutathione depletion and the possibility of a rescue treatment.

We report the results of a phase II evaluation of carboplatin (CBDCA) in 45 patients with advanced malignant melanoma. Of the 43 evaluable patients, 6 had been treated previously with chemotherapy; 11 had been treated with immunotherapy. The initial dose was 400 mg/m2 i.v. every 4 weeks; the dose was modified as required to achieve moderate myelosuppression. There was one complete response (duration 16 months) and six partial responses, for a major objective response rate of 16%. Toxicity consisted primarily of acute nausea and vomiting, and thrombocytopenia. The activity of CBDCA in this disease is similar to that of cisplatin and dacarbazine.
