Twenty-five patients with disseminated cancer (nine with renal cell carcinoma, five with melanoma, three with Hodgkin's lymphoma and chronic myelocytic leukemia [CML], two with soft tissue sarcoma, one each with large-cell lymphoma, breast cancer, and colon cancer), 13 males and 12 females, aged 25 to 68, were treated with recombinant human interleukin-2 (rIL2) by continuous infusion and adoptive transfer of autologous lymphocytes activated in vitro with IL2. Patients underwent leukapheresis on days 1, 8, 15, and 22 of the treatment. Cells, bulk activated for 20 hours in serum-free culture medium with 1,000 U IL2/mL in transfusion transfer packs as culture vessels, were transfused the following day. The infusion of IL2 by continuous infusion for six days started immediately after each adoptive transfer for 4 weekly courses. The dose of IL2 was escalated weekly in each patient; starting doses of IL2 were also escalated in subsequent cohorts of patients until maximally tolerated doses were reached. Nine patients had objective tumor regressions (three with renal cell cancer, two with Hodgkin's lymphoma, and one each with melanoma, sarcoma, breast, and colon cancer). Six responses were partial, two were minor, and one was mixed. Responding patients were maintained with IL2 by continuous infusion for six days every 6 to 8 weeks, without adoptive cell transfer. The median duration of responses was 16 weeks (3 to 60 + weeks). Tumor regression was related to the dose of IL2 (greater than or equal to 3.4 x 10(6) U/m2/d for six days) and to the in vivo lymphoproliferative effects of the lymphokine, but not to the total number of cells adoptively transferred. Side effects of treatment were transient and quickly reversible. Renal, hepatic dysfunction, and dyspnea were directly related to the dose of IL2 and to lymphocytosis. Other toxicities were mild hypotension with mild fluid retention, oral mucositis, anemia, thrombocytopenia, fever, and fatigue.

Forty-seven patients with metastatic malignant melanoma took part in a phase II trial of tauromustine (TCNU), a new chlorethylnitrosourea based on the endogenous amino acid taurine. TCNU was given orally at a dosage of 130 mg/m2 every fifth week. No patient had previously received cytotoxic therapy. Among 37 evaluable patients, 26 patients experienced progressive disease including seven patients with early death, five showed no change, and six partial responses, yielding an objective response rate of 16%. Responses were limited to subcutaneous, lymph node, bone and lung metastases. Median time to progression was 26 weeks for responders. The treatment schedule was well tolerated with a median dose of 88% of the predicted dose given during all cycles. Dose-limiting toxicity was thrombocytopenia. It appears that TCNU is active in disseminated malignant melanoma with a response rate similar to other nitrosoureas.

High-dose interleukin-2 (IL-2) with or without lymphokine-activated killer (LAK) cells has been reported to have activity in certain solid tumors, but toxicity has usually required hospitalization for administration. The purpose of this trial was to determine the antineoplastic effect and toxicity of IL-2 administered at a lower dose in an outpatient setting. Eligibility criteria included measurable disease, Karnofsky performance greater than or equal to 70%, age greater than 18 years, and adequate bone marrow, renal, and hepatic function. The median age of 35 patients was 56 years (range, 20 to 75). Diagnoses included malignant lymphoma (ML), (nine patients), chronic lymphocytic leukemia (CLL) (eight), melanoma (eight), colorectal cancer (six), renal cancer (two), and breast cancer (two). The initial 18 patients were treated with 1 mg/m2 (3 x 10(6) U/m2 intravenous [IV] bolus) for five days every other week for a total of 4 treatment weeks (8 weeks total). The subsequent 17 patients were treated with 0.5 mg/m2 (1.5 x 10(6) U/m2). All patients were evaluable for toxicity, and 26 for tumor response. Toxicities included fatigue (71%), nausea (69%), hypotension (54%), fever (51%), chills (40%), weight gain (37%), pruritus or rash (31%), dyspnea (14%), azotemia (6%), confusion (6%), thrombocytopenia (6%), and myocardial infarction (3%). Four patients died from apparently unrelated causes within the first 2 weeks of treatment. Treatment was discontinued before the completion of 8 weeks of treatment because of progressive disease (12 patients), severe hypotension (three), azotemia (one), myocardial infarction (one), early death (four), and miscellaneous causes (two). IL-2 at 1 mg/m2 IV for five days is associated with moderate toxicity, but a dose of 0.5 mg/m2 is tolerable for outpatient administration. Three partial responses (PR) and one minor response (MR) lasting 1 to 17+ months have been observed in 12 patients with ML and CLL evaluable for response. One additional MR was observed in a patient with melanoma. IL-2 deserves further study in patients with ML and CLL.

Escalating doses of recombinant human interleukin-2 (rIL-2) were combined with long-term cultured rIL-2 activated killer cells to treat patients with disseminated melanoma, renal cell cancer, and colon cancer. Twenty-four patients were entered, 12 with renal cell cancer, 8 with colon cancer, and 4 with melanoma; 23 were evaluable for efficacy and toxicity. The (dose-related) toxicities were moderate to severe and consisted of fever, chills, rigors, weight gain, hypotension, mild confusion, elevation of liver enzymes and serum creatinine, thrombocytopenia, and eosinophilia. No cardiac events (arrhythmias or myocardial infarction) were recorded. None of the patients were admitted to the intensive care unit, and no deaths occurred. Two partial responses were observed, one at relatively low doses of rIL-2 in a patient with renal cell carcinoma and one at the highest dose level in a patient with malignant melanoma. The maximally tolerated dose level of rIL-2 for this study was 6 X 10(6) U/m2 i.v./day. The recommended dose for further studies is 3 X 10(6) U/m2 i.v./day in three divided doses.

Twenty-seven patients with metastatic cancer were treated with a daily continuous intravenous (IV) infusion of recombinant human interleukin-2 (rhIL-2) along with daily intramuscular recombinant interferon-alpha-2a (rIFN-alpha-2a) 4 days per week for 4 weeks with repeated treatment after 2 to 4 weeks of rest. The maximum-tolerated dose (MTD) was 3 million U/m2/d of rhIL-2 with 5 to 10 million U/m2/d of rIFN-alpha-2a. The dose-limiting toxicities are moderate hypotension requiring low doses of pressors and chronic fatigue associated with decreased performance status. Other common side effects included fever, chills, fluid retention, nausea/vomiting, erythrodermia, weight loss, elevated liver transminase levels, anemia, thrombocytopenia, and CNS toxic effects. There were seven objective responses among 25 evaluable patients. Four major responses (one complete response and three partial responses) were observed among 10 patients with melanoma treated with the MTD level. These data suggest that for cancer patients, concomitant rhIL-2 and rIFN-alpha-2a therapy is tolerable and has manageable side effects. Further phase II studies will be needed to define the antitumor activity of this combination.

The results of 63 patients with advanced malignant tumors treated by combined chemotherapy including high-dose cisplatin (HD-DDP) (single dose 50-100 mg/m2) are reported. The remission rates and duration of the remission for various malignant tumors were: 40% (10 PR out of 25 patients) and 3-8 months for non-small cell lung cancer (NSCLC) treated by PMFV (DDP, MMC, 5FU and VCR) regimen; 87% (4 CR and 9 PR out of 15) and 3-14 months for breast cancer treated by PCMF (DDP, CTX, MTX and 5FU) regimen; 100% (1 CR and 3 PR out of 4) and 3-10 months for testicular cancer treated by PPV (DDP, Pingyangmycin and VCR) regimen; 57% (1CR and 3 PR out of 7) and 5-12 months for malignant melanoma treated by PBDV (DDP, BCNU, DTIC and VCR) regimen; 33% (2 PR out of 6) and 5 months for esophageal cancer treated by PPV regimen. In 6 patients with other malignant tumors, the remission rate was 50% (3 PR). The results show that the combined regimens including HD-DDP in the treatment of breast cancer and NSCLC (remission rate 87% and 40%, respectively) are better than that including low-dose DDP (17% and 7%) (P less than 0.001, P less than 0.01) and that including adriamycin (30% and 13%) (P less than 0.001, P less than 0.05). In the treatment, obvious gastrointestinal reaction, leukopenia, thrombocytopenia and mild functional damage of the liver and kidney were observed.

Trimetrexate glucuronate (TMTX) is a methotrexate (MTX) analog that is active against transport-deficient MTX-resistant tumor cells. We performed a phase I study of TMTX administered by daily bolus for 9 consecutive days since this schedule is one of the most active in experimental murine tumor models. The drug was administered in this fashion every 4 weeks for at least two cycles. Fifteen patients with refractory metastatic cancers were studied and all had received prior chemotherapy. The dose-limiting toxicity was a rapidly reversible thrombocytopenia first seen at a daily dose of 4.0 mg/m2 which occurred 7 days after the end of TMTX administration. There was great inter- and intrapatient variability in the platelet nadirs observed in the six patients treated at 4.0 mg/m2. One patient died of massive hemoptysis during a platelet nadir at that dose level. Granulocyte counts never dropped below 1500/mm3. Only one patient had significant non-hematological toxicity: a radiation recall skin toxicity along with a self-limited maculopapular rash. One patient with melanoma and lung metastases treated at 4.0 mg/m2 had a partial response. TMTX plasma levels were measured by HPLC every 3 days prior to daily dosing in patients receiving 4 mg/m2 to determine whether drug accumulation occurred during this prolonged administration schedule. Nadir drug levels varied from less than 0.02 to 0.35 microM and did not seem to increase during the 9-day schedule in individual patients. By comparison with other phase I trials, the hematologic toxicity of TMTX seems to be schedule-dependent, with less drug being tolerated and more severe thrombocytopenia observed with more protracted treatment protocols. A firm phase II starting dose for daily bolus X 9 schedules is difficult to recommend in view of the variable toxicity observed in the patients treated at 4.0 mg/m2 daily, who, in addition, had all been extensively pretreated. A reasonable starting dose might be 3.0 mg/m2 daily with built-in dosage increases or decreases.

Difluoromethylornithine (DFMO) is an irreversible enzyme-activated inhibitor of ornithine decarboxylase, a key enzyme in polyamine synthesis. We have screened for potential anti-cancer activity of DFMO using a clonogenic assay, which suggested that melanoma might have sensitivity to this agent. Accordingly, we have performed a phase II trial of DFMO (2 g/m2 po q 8 h) in 24 patients, 21 of whom were evaluable for response. One patient achieved a complete response of a large subcutaneous mass for 11 months. Although stabilization is frequently difficult to measure, seven patients appeared to stabilize previously active disease, with a median duration of response of eight weeks. Toxicity was significant and DFMO was discontinued in five patients due to side effects - hearing loss alone in four and hearing loss associated with thrombocytopenia in the fifth patient. Hearing changes occurred in ten patients. Other side effects were mild. These data indicate that DFMO as a single agent may be an effective therapy for melanoma. A phase II trial of DFMO in previously untreated patients using a different schedule to decrease hearing loss is warranted. Additionally, several in vitro and animal models suggest that DFMO plus interferon are synergistic, and this combination might be used for a clinical trial as well.

Thirty-three patients with disseminated malignant melanoma were entered in a phase II study of the new nitrosourea S 10036 using a 100-mg/m2 weekly induction schedule for 3-4 consecutive weeks. Patients who responded to this treatment were followed with a maintenance therapy every 3 weeks. Toxic effects were mainly hematological and consisted of delayed thrombocytopenia and leukopenia. Among 30 patients who could be evaluated, eight partial responses were observed (response rate, 26.67%); among seven patients with cerebral metastasis, two partial responses were observed. This multicentric study is currently being continued to confirm this interim report.

Iproplatin [cis-dichlor-trans-dihydroxy-bis-isopropylamine platinum (CHIP, JM9)] is a new antineoplastic platinum analogue with an octahedral conformation. It has more water solubility than does cisplatin and was found to have less neurotoxicity and nephrotoxicity in experimental animals than cisplatin. Like cisplatin, it has been demonstrated to have a broad spectrum of activity in experimental tumor systems. A phase I study of iproplatin was conducted in 28 patients (12 with melanoma, 8 with sarcoma, 6 with breast cancer, and 2 with colon cancer). All patients had failed prior chemotherapy. Four consecutive doses of iproplatin were administered at weekly intervals followed by a rest period of two weeks for hematologic recovery (one course). One hundred forty-two weekly doses were administered with all patients except three receiving at least one full course. The weekly starting dose of 40 mg/m2 was increased to 120 mg/m2 given over 30 minutes without hydration. Myelosuppression predominantly thrombocytopenia, was the dose-limiting toxicity at weekly doses of greater than or equal to 95 mg/m2 per course. With iproplatin doses 75 mg/m2, 95 mg/m2, and 120 mg/m2, the lowest median granulocyte counts were 2.6 x 10(3)/mm3, 2.2 x 10(3)/mm3, and 1.8 x 10(3)/mm3, respectively. Similarly, at iproplatin doses of 75 mg/m2, 95 mg/m2, and 120 mg/m2, the lowest median platelet counts were 144 x 10(3)/mm3, 99 x 10(3)/mm3, and 31 x 10(3)/mm3, respectively. Mild to moderate nausea and vomiting were observed in the majority of patients. No significant neurotoxicity, nephrotoxicity, or ototoxicity was observed. Objective tumor regression was not observed in this study.(ABSTRACT TRUNCATED AT 250 WORDS)
