AMSA an acridine derivative, was administered to 35 adults with previously treated advanced sarcomas. Patients with adequate bone marrow reserve received 120-150 mg/m2 of AMSA as a single dose repeated every 3 weeks. Patients with inadequate bone marrow reserve received 100-120 mg/m2 of AMSA. Among 31 evaluable patients, there was one partial response that lasted 6 months in a patient with intra-abdominal malignant fibrous histiocytoma with liver metastases. Thirteen patients had stable disease with a median time to disease progression of 5 months (range, 2-13), while 17 patients demonstrated progressive disease with a median time to disease progression of 2 months (range, 1-3). The median survival time for the 31 evaluable patients in this study was 5 months. The toxic effects were mild and included myelosuppression, nausea and vomiting, fever of unknown origin, and fatigue. At the dose and schedule used in this study, AMSA does not appear to have any significant activity in advanced sarcomas of adults.

Both DFMO and methyl-GAG inhibit sequential enzymatic reactions in the pathway of polyamine biosynthesis. Since polyamines may be important factors in proliferation of cancer cells, we initiated a phase-I study of these agents in patients with advanced cancer. DFMO was given by mouth at a constant daily dose of 4 g/m2 starting on day 1 of the treatment protocol. The dose of methyl-GAG ranged from 200 to 700 mg/m2 administered IV every 2 weeks beginning on day 4. Twenty-two patients were entered into the protocol. Toxic reactions to this therapy were dose-related and included nausea, fatigue, diarrhea, and myelosuppression. One patient with colon cancer experienced a greater than 50% decrease in measurable disease but developed severe myelotoxicity. While DFMO was well tolerated, the combination of drugs appeared to cause substantially more hematologic and gastrointestinal toxicity than encountered during our recent experience with methyl-GAG used alone. We suggest that future studies of this drug combination carefully evaluate levels of polyamines and inhibition of enzymatic activity to minimize toxicity.

Thirty-three patients were treated in an escalating single-dose trial of partially purified nonrecombinant interferon-gamma (IFN-gamma). The first seven patients received intramuscular injections of IFN-gamma in doses up to 20 X 10(6) units/m2. When it became clear that these patients had no detectable antiviral activity in their serum, subsequent patients were treated by the intravenous route of administration, generally with 2-h infusions. A total of 26 patients received the agent intravenously in single escalating doses ranging from 0.2 to 60 X 10(6) units/m2, on a twice-weekly schedule for 4-6 weeks. The most common toxicities encountered included fever, chills, fatigue, anorexia, and occasional nausea and vomiting. No myelosuppression or hepatic toxicity was observed. A maximum tolerated dose for single-dose intravenous administration was defined as 50 X 10(6) units/m2 on the basis of unacceptable fatigue and prolonged systolic hypotension. Antiviral activity was detected in the serum following doses greater than 2 X 10(6) units/m2 when the IFN-gamma was administered intravenously. No evidence of antitumor activity was seen in this Phase I trial, although the treatment regimen employed did not lead to high or prolonged levels of serum IFN activity in the majority of patients. An accurate assessment of the antitumor activity of this particular IFN-gamma preparation will require Phase II trials employing multiple-treatment regimens.

This study was designed to evaluate the clinical tolerance to multiple IM injections of rDNA-produced human alpha-2 interferon (IFN) (Schering-Plough 30500) in patients with solid tumours. IFN was administered in escalating IM doses in separate groups of patients daily for 14 days and then twice weekly for a further 10 weeks. The dosage levels were 1, 3, 10, and 30 million U/injection. Subjective toxicity could be divided into two types, acute and chronic. The acute reactions took the form of an influenza-like syndrome consisting in chills, rigors, headache, tremor, nausea, vomiting, and myalgia. These symptoms were dose-related but tachyphylaxis developed with continued dosing. The chronic toxicity consisted of malaise, lethargy, fatigue, anorexia, and confusion. These symptoms were not so dose-dependent and tended to become more severe with prolonged treatment. Objective toxicity consisted of myelosuppression and liver dysfunction. Granulocyte counts below 1.0 X 10(9)/l were seen in three patients at the 30-million-U level, with platelet counts less than 100 X 10(9)/l in two of these. Elevation of the liver enzymes were seen in all five patients treated at 30 million U, but returned to normal after 1 week without IFN in all but one patient. A tolerable dose (IM) for phase II/III studies lies between 3 and 10 million U for daily scheduling and between 10 and 30 million U for twice-weekly injections.

Interferon has been shown to have antineoplastic activity but an optimal dose schedule has not been defined. In this phase I study 12 patients with advanced cancer were treated with weekly high-dose human lymphoblastoid interferon given by 3-hour iv infusion to assess toxicity. The median maximum tolerated dose was 55 X 10(6) units/m2 and the dose-limiting toxicity was a complex of fever, fatigue, myalgias, anorexia, and weakness. Neither myelosuppression nor hepatotoxicity was encountered. One patient with metastatic melanoma achieved complete remission, which has been maintained for 2 years. Weekly high-dose iv infusion of interferon has antineoplastic activity, did not cause myelosuppression or hepatotoxicity, and was well-tolerated up to doses of 40-50 X 10(6) units/m2. Future trials should start at 30 X 10(6) units/m2 and should escalate by 10 X 10(6) units/m2/week to patient tolerance.

Fifty-two patients with advanced cancer received sequentially escalating doses of 3 to 50 million units of recombinant DNA-produced alpha interferon by daily intramuscular injection. There were 23 patients with metastatic breast cancer, 17 patients with nodular poorly differentiated lymphocytic lymphoma, and 12 patients with multiple myeloma. Complete and partial remissions were obtained in 35 percent of patients with nodular poorly differentiated lymphoma, whereas rare activity was found in breast cancer and multiple myeloma. Dose-limiting toxicity occurred in patients receiving 36 million units or more and consisted of fatigue/asthenia, weight loss, and elevation of transaminase levels, requiring frequent interruption, reduction in dose, or cessation of treatment. Hematologic toxicity was rarely a limiting factor, but myelosuppression was severe in some patients with multiple myeloma. All toxicities were reversible on discontinuation of treatment. Antibodies to recombinant leukocyte A interferon were seen infrequently but may adversely affect therapy.

Four patients with adult T-cell leukemia (ATL) and 4 patients with non-Hodgkin's lymphoma were treated with alpha-type interferon (Human Lymphoblastoid Interferon: HLBI). Treatment regimen consisted of 3 to 12 million units (MU) of HLBI given intramuscularly once daily. The total dose varied from 36 to 520 MU. Complete remissions were obtained in one of 4 patients with ATL and one of 3 patients with B-cell lymphoma. A partial remission was yielded in one patient with B-cell lymphoma. An overall response rate (CR + PR) was 37.5%. Toxicity included flu-like symptoms, myelosuppression, G-I tract symptoms, fatigue, high fever and hepatic disturbance. On the basis of this study, we have concluded that HLBI is effective for the treatment of ATL and B-cell lymphoma.

Marcellomycin is a new anthracycline that was proposed for clinical trials on the basis of experimental data suggesting reduced potential for hematologic and cardiac toxicity as compared to conventional anthracyclines. This phase I trial was designed to determine the maximum tolerated dose of marcellomycin at a single-dose schedule. The drug was given as a 15-to 30-min i.v. injection. Eighteen patients with a variety of solid tumors received a median of 2 courses (range: 1-5) at doses of 5-60 mg/m2. Myelosuppression was dose-limiting and somewhat unpredictable. It was characterized by early thrombocytopenia and late leukopenia. It occurred at doses greater than or equal to 40 mg/m2 and resulted in a few cases of infection and hemorrhage. Nausea, vomiting and stomatitis were frequent and occasionally severe. Other common non-hematological toxic effects consisted of local phlebitis and fatigue. Electrocardiographic changes were also encountered. Hair loss was rare and negligible. No antitumor activity could be detected. It appears that phase II trials should be preferably restricted to ambulatory patients and that a dose schedule of 50 mg/m2 repeated every 3 weeks may be proposed for this favorable patient population.

Marcellomycin, a new anthracycline antibiotic, was administered intravenously on a weekly schedule to 22 patients with advanced malignant solid tumors. Patients were treated at 6 dosage levels ranging from 5 to 30 mg/m2 weekly for 4 weeks. Courses were repeated after a 3-week rest period. Hematologic toxicity was dose-limiting but unpredictable. Of 10 patients treated with weekly doses of 27.5 mg/m2, 3 patients exhibited myelosuppression and 2 died in agranulocytosis. Moderate to severe nausea and vomiting occurred in 19 of 22 evaluable patients. Other toxic effects were non-acute and consisted of mild stomatitis, diarrhea, phlebitis and moderate fatigue in 1-3 patients each. In 17 patients evaluable for antitumor activity no partial or complete responses occurred. One patient with advanced breast cancer showed a mixed response. Marcellomycin given on a weekly dose schedule has unpredictable and erratic hematologic toxicity. The maximally tolerated dose appears to be between 27.5 and 30 mg/m2 weekly. However, no firm recommendations can be given for a dose level that results in tolerable, predictable and reversible toxicity.

Maintenance treatment with FT-207 was applied to 92 patients with uterine cancers after initial treatments were performed. Daily dosage of FT-207 was either 600 or 800 mg and the drug was administered orally. The duration of 6 months and the total dosage of 100 g were proposed as administration schedule and 34 patients (37%) received this regimen. Side effects during the treatment were observed in 35 cases (38%). Gastrointestinal disturbance was most frequently observed and other side effects included myelosuppression, general fatigue, hepatic dysfunction and skin toxicities. There were no serious side effects, the treatment was continued in most patients and was interrupted only in 7 cases (8%). In the cases of recurrence or advanced cancer, however, the side effect was the predominant cause for interruption of administration. As for the antitumor effect of the treatment, a survival rate of the patients with cervical cancer of early stages was evaluated. Three-year survival rate in the treatment group was higher comparing to the one reported hitherto.
