A Phase I-II study with 4'-epi-doxorubicin (epi-DX) was performed in 108 patients with various types of advanced malignancy. The pattern of acute toxicity was similar to that of doxorubicin (DX). However, epi-DX was better tolerated than DX because of comparative lower incidence of vomiting, stomatitis, complete alopecia and severe myelosuppression. Cardiac toxicity was studied by utilizing noninvasive methods, and the electrocardiographic results suggested a slightly lower cardiac damage after epi-DX compared to DX. Antitumor activity was documented in a variety of neoplasms, and objective response was also observed in those considered refractory to DX such as malignant melanoma and renal cancer. X

The feasibility of high-dose AMSA followed by autologous bone marrow rescue was studied in seven patients with solid tumors. They received a total of 12 courses of treatment. Total doses ranged from 600 to 1000 mg/m2/course. Major toxic effects were myelosuppression, fever of unknown origin, and stomatitis. One patient with malignant melanoma had stable disease lasting 2 months; the other six had progressive disease.

Twenty-seven patients with advanced solid tumors (ten with lung cancer, eight with sarcoma, five with melanoma, four with miscellaneous tumors) were treated with high-dose doxorubicin (120 mg/m2) every 3 weeks for a total of 75 courses. As expected, marked myelosuppression was observed, with all patients having a granulocyte count nadir of less than 500 cells/mm3. The median platelet count nadir was 91 X 10(3)/mm3 following the first cycle and 50 X 10(3)/mm3 following the fourth cycle. Moderate or severe stomatitis was seen with 65% of the courses, and 46% of the courses were complicated by fever greater than 101 degrees F. Congestive heart failure was observed in only one patient after five cycles (600 mg/m2) of high-dose therapy. This patient has received 540 mg/m2 of doxorubicin 2 years previously. Radionuclide ventriculography (MUGA) performed serially in 12 patients (eight of whom received 480 mg/m2) and clinical evaluation did not suggest an increased risk of cardiotoxicity at this dose rate. Overall, 11 of 24 (46%) evaluable patients responded (58% if patients with malignant melanoma are excluded). Responses included one complete and three partial responses in eight evaluable patients with lung cancer, one complete and two partial responses in seven evaluable patients with sarcoma, and no objective responses in five patients with malignant melanoma. With appropriate supportive care, repetitive courses of doxorubicin at a dose of 120 mg/m2 can be given to patients of good performance status without a major increase in cardiotoxicity. However, the low complete remission rate, considering the observed toxicity, does not justify routine use of this regimen in patients with solid tumors.

53 patients with advanced and measurable cancerr were treated with vindesine in doses of 3 mg/m2 (pretreated) and 4 mg/m2 (non pretreated) i.v. once weekly. 48 patients are evaluable for response: of 14 patients with squamous cell carcinoma of the lung, 1 partial remission (PR), 1 minor response (MR) and 1 no change (NC) were observed. In 5 patients with large cell carcinoma of the lung: 1 NC. In 3 with adenocarcinoma of the lung: 1 MR. One patient with nasopharyngeal carcinoma had progressive disease. Stable disease was observed in a patient with carcinoma of the tongue and in a patient with adenocarcinoma of the esophagus. Four patients with colorectal carcinoma had progressive disease. One MR was observed in a patient with breast cancer, while all of the other 3 patients had progressive disease. One carcinoma of the penis was stable. One MR was observed in a patient with Hodgkin's disease. One PR was observed in a case with no-Hodgkin's lymphoma. A patient with acute leukemia had progressive disease. Among 9 patients with malignant melanoma, 3 had an MR and 1 patient had stable disease. A patient with fibrosarcoma had progressive disease. Observed toxicity included leukopenia, thrombocytopenia, anemia, paresthesias, constipation, jaw pain, nausea, stomatitis, alopecia, loss of taste, pruritus and skin rash, weakness and fatigue.

N-Phosphonacetyl-L-aspartic acid (PALA) is new synthetic antimetabolite which inhibits de novo pyrimidine biosynthesis. Its significant activity against Lewis lung carcinoma, B16 melanoma, and glioma 26 suggested that it might be useful in the treatment of human solid tumors. Phase I trials revealed that dose-limiting toxicity included skin reactions, diarrhea, and stomatitis. Pharmacologic studies demonstrated rapid renal excretion of more than 70% of the unmetabolized drug in 24 h. Peak plasma levels correlated with dose of PALA administered. Partial responses to PALA were seen in one patient with melanoma, one with chondrosarcoma, and one with colon carcinoma. The potential for PALA's use in combination chemotherapy, particularly with 5-fluorouracil, is discussed.

Rhizoxin is a new anti-tumour agent isolated from the pathogenic fungus Rhizopus chinensis. It has shown broad activity against murine tumour models and is also active against vinca alkaloid-resistant cells. The purpose of our studies was to determine the clinical activity of this compound in patients with advanced breast cancer and melanoma. Based on the results of a phase I study, 2.0 mg m-2 was administered as intravenous infusion over 5 min every 21 days. Nineteen patients were entered into the breast cancer phase II trial and received a total of 50 courses (median 2, range 1-6). Of these, dose reductions were performed in three courses because of leucopenia or stomatitis (1.5 mg m-2, one course; 1.45 mg m-2, two courses). Twenty-six patients were entered into the melanoma trial and received a total of 70 courses (median 2, range 1-12). No dose reductions were required. All patients were eligible for toxicity. Haematological toxicity included neutropenia CTC grade 3 (29/120 courses, 24.2%) and grade 4 (11/20 courses, 9.2%). Only drug-related CTC grade 1 thrombocytopenia was observed. Non-haematological toxicity included alopecia in all patients after two courses of treatment as well as CTC grade 3/4 stomatitis and asthenia. In the breast cancer study, one patient achieved a more than 50% tumour reduction after six cycles but was progressing after 6 weeks. Another patient showed a partial remission after the first course but was taken off the study because of CTC grade 3 skin toxicity. One patient was not evaluable for response (early death). No objective remissions were observed in 15 evaluable patients. In melanoma, no objective remissions were observed. We conclude that rhizoxin can be safely administered at 2.0 mg m-2 every 3 weeks. However, it has little activity in patients with advanced breast cancer and melanoma.

Manganese superoxide dismutase (MnSOD) is induced by interferon-gamma (IFN-gamma) in various cell lines. To determine whether MnSOD plays a role in the antiviral action of IFN-gamma, we employed an antisense strategy to inhibit the expression of MnSOD in the human melanoma cell line, A375. Three antisense-containing clones that exhibited reduced induction of MnSOD were investigated with respect to their response to the antiviral protective effects of IFN-gamma and IFN-alpha. We observed a striking decrease in the ability of IFN-gamma to protect antisense clones from vesicular stomatitis virus infection (VSV). The IFN-alpha induced antiviral state was also impaired, but to a lesser degree than was observed with IFN-gamma. We excluded the possibility that these effects were caused by a higher sensitivity of the antisense cells to VSV itself and found that the antisense clones actually were less sensitive to VSV. Therefore, we conclude that MnSOD is involved in the establishment of the IFN-gamma-induced antiviral state and to a lesser degree in the antiviral actions of IFN-gamma.

A phase II study was undertaken to evaluate the clinical efficacy and safety of docetaxel in patients with malignant melanoma. Between April 1992 and February 1996, 37 patients with metastatic malignant melanoma and no prior chemotherapy were treated with docetaxel 100 mg m-2 administered intravenously over 1 hour every 21 days. Patients were premedicated prior to each course with dexamethasone and diphenhydramine. Toxicity and follow-up were provided. Objective responses were seen in two out of 35 patients evaluable for response, one complete response and one partial response. These two responses were of a duration of greater than two years. The most common toxicity was grade 4 neutropenia, which occurred in 92% of patients; 49% required hospitalization for an episode of neutropenic fever. Additional patients had reversible grade 3-4 toxicities including nausea, vomiting, diarrhea, stomatitis, arthralgias, myalgias, peripheral neuropathy and fatigue. Eighteen patients had hypersensitivity reactions, two were grade 3-4. Fluid retention, grade 1-3 was observed in seven patients. Alopecia occurred in most patients. Docetaxel has definite but low-level activity against malignant melanoma. Further investigation of this drug should be considered in multidrug combination programs.

Treatment for metastatic melanoma is limited by low response rates to single- or combination-agent chemotherapy. Recent studies have examined the role of biologic modifiers and differentiating agents. This phase II study examined the efficacy and toxicity of combining alpha-2b-interferon (IFN alpha) and 13 cis retinoic acid (cRA) in the treatment of metastatic malignant melanoma. Thirteen patients were treated with IFN alpha (5 x 10(6) units/m2 three times weekly) and cRA (1 mg/kg per day). One patient with lung and adrenal metastases had a partial response 6 months in duration and two patients had stabilization of lung metastases for 2 months. All other patients had progressive disease. Toxicity was substantial with all patients experiencing Eastern Cooperative Oncology Group grade 1-2 fatigue, myalgias, anorexia, stomatitis, and cheilitis. In addition, serum cholesterol and triglycerides were elevated in all patients. Seven patients required 50% dose reductions because of hypertriglyceridemia, fatigue associated with a significant decline in performance status, and severe stomatitis with anorexia and weight loss. One patient discontinued therapy because of a decline in performance status. This study suggests this combination of cRA and IFN alpha is inactive in the treatment of metastatic melanoma and is associated with substantial toxicity.

A Phase I dose escalation trial of i.v. administered recombinant human interleukin 12 (rhIL-12) was performed to determine its toxicity, maximum tolerated dose (MTD), pharmacokinetics, and biological and potential antineoplastic effects. Cohorts of four to six patients with advanced cancer, Karnofsky performance >/=70%, and normal organ function received escalating doses (3-1000 ng/kg/day) of rhIL-12 (Genetics Institute, Inc.) by bolus i.v. injection once as an inpatient and then, after a 2-week rest period, once daily for five days every 3 weeks as an outpatient. Therapy was withheld for grade 3 toxicity (grade 4 hyperbilirubinemia or neutropenia), and dose escalation was halted if three of six patients experienced a dose-limiting toxicity (DLT). After establishment of the MTD, eight more patients were enrolled to further assess the safety, pharmacokinetics, and immunobiology of this dose. Forty patients were enrolled, including 20 with renal cancer, 12 with melanoma, and 5 with colon cancer; 25 patients had received prior systemic therapy. Common toxicities included fever/chills, fatigue, nausea, vomiting, and headache. Fever was first observed at the 3 ng/kg dose level, typically occurred 8-12 h after rhIL-12 administration, and was incompletely suppressed with nonsteroidal anti-inflammatory drugs. Routine laboratory changes included anemia, neutropenia, lymphopenia, hyperglycemia, thrombocytopenia, and hypoalbuminemia. DLTs included oral stomatitis and liver function test abnormalities, predominantly elevated transaminases, which occurred in three of four patients at the 1000 ng/kg dose level. The 500 ng/kg dose level was determined to be the MTD. This dose, administered by this schedule, was associated with asymptomatic hepatic function test abnormalities in three patients and an onstudy death due to Clostridia perfringens septicemia but was otherwise well tolerated by the 14 patients treated in the dose escalation and safety phases. The T1/2 elimination of rhIL-12 was calculated to be 5.3-9.6 h. Biological effects included dose-dependent increases in circulating IFN-gamma, which exhibited attenuation with subsequent cycles. Serum neopterin rose in a reproducible fashion regardless of dose or cycle. Tumor necrosis factor alpha was not detected by ELISA. One of 40 patients developed a low titer antibody to rhIL-12. Lymphopenia was observed at all dose levels, with recovery occurring within several days of completing treatment without rebound lymphocytosis. There was one partial response (renal cell cancer) and one transient complete response (melanoma), both in previously untreated patients. Four additional patients received all proposed treatment without disease progression. rhIL-12 administered according to this schedule is biologically and clinically active at doses tolerable by most patients in an outpatient setting. Nonetheless, additional Phase I studies examining different schedules and the mechanisms of the specific DLTs are indicated before proceeding to Phase II testing.
