Two hundred three patients (median age 26 years; range 18-45) with untreated multiple and widespread anogenital condyloma were randomly assigned to one of four study arms in order to compare the efficacy, toxicity, and tolerability of recombinant interferon alpha-2b with those of diathermocoagulation. Of 200 evaluable patients, 51 were treated intramuscularly (IM) with 3 x 10(6) U (3 MU)/m2 daily for 3 weeks (total dose 63 MU/m2), 50 received subcutaneous thrice-weekly injections of 3 MU/m2 for 4 weeks (total dose 36 MU/m2), 51 underwent diathermocoagulation, and 48 were not treated and were used as a control group. Six months after the end of treatment, the overall response rate (complete and partial responses) was 70%: 57 and 82% for patients receiving interferon alpha-2b (IM and subcutaneously) and diathermocoagulation, respectively, and 8% for the control group. After 6 months from therapy, no significant differences in complete response were found among the different types of treatment: 20, 20, and 35% for the two interferon groups and the diathermocoagulation group, respectively. Fifteen and two complete responders in the cauterization and interferon groups, respectively, experienced disease recurrence (P less than .01). All patients given interferon therapy complained of flu-like symptoms, which declined progressively after the first week of treatment. Fatigue, lasting as long as patients received interferon, was the most prevalent chronic side effect. We conclude that systemic recombinant interferon alpha-2b is active in treating patients with primary condyloma lesions and does so as well as cauterization.(ABSTRACT TRUNCATED AT 250 WORDS)

Twenty-seven patients with Philadelphia chromosome positive chronic myelogenous leukaemia in the chronic phase were treated with low doses of recombinant interferon (IFN) alpha-2b. Ten patients entered a complete and six a partial haematologic remission with a median duration of 5.8 and 9.1 months respectively. Five minor cytogenetic responses were observed. These results are inferior compared to other studies with higher interferon-doses. Fever was an acute side effect after injection of IFN, limb pains and fatigue occurred protractedly. Haematologic side effects, nonspecific EEG changes, weight loss, and development of pulmonary infiltrates were observed in later periods of the treatment. Eight patients developed neutralizing anti-IFN antibodies after 4.2-20.4 months (median 12.8 months). Anti-IFN antibodies were associated with relapse or refractoriness to IFN treatment: five out of nine patients with rising WBC after initial fall had antibodies, while four did not. Two out of four patients with primary non-response had IFN-antibodies. These results may indicate a serious problem in the long-term treatment of CML with recombinant interferon.

Based on a preclinical study demonstrating the synergistic antitumor effect of recombinant interleukin 2 (rIL-2) and beta-interferon (IFN-beta) on mouse tumors and previous results of a phase I study of rIL-2, a phase I study of combination therapy with human rIL-2 and IFN-beta was conducted in 26 patients with advanced malignancy. Patients were given rIL-2 by 24-h continuous i.v. infusion and IFN-beta by 2-h i.v. infusion for 5 days each week for 4 weeks. The common side-effects were fever, malaise, chills, appetite loss, and diarrhea. Leukocytosis and eosinophilia were observed in 56% and 69% of the patients, respectively. Transient leukopenia and thrombocytopenia were also observed in some patients. Dose-limiting manifestations were intolerable fatigue and liver dysfunction, and it was concluded that the maximum tolerated doses of rIL-2 combined with IFN-beta were 1.1 x 10(6) U/m2/day for rIL-2 and 6.0 x 10(6) IU/m2/day for IFN-beta. No patients achieved complete and partial response to therapy in this study. One patient with pulmonary metastasis from pharyngeal cancer showed a minor response. Natural killer (NK) and lymphokine-activated killer (LAK) activities increased during the 5 days of treatment and decreased during the 2-day intermission. The percentage of IL-2 receptor-positive cells increased markedly until Day 12, and gradually decreased thereafter. The percentage of OKT 4-positive cells and the OKT 4/OKT 8 ratio increased. In contrast, the percentage of Leu 7- or Leu 11-positive cells decreased over the 4-week treatment. A phase II study of this combination therapy is ongoing against head and neck cancer, and renal cell carcinoma.

Twenty-two patients with Stages Ia to IVa cutaneous T cell lymphoma were entered into a controlled trial of interferon alfa-2a (Roferon-A). Patients initially received either 3 million IU interferon alfa-2a, or their dosage was escalated to 36 million IU intramuscularly daily for a 10-week induction period. At the end of induction, 14/22 (64%) of patients had an objective antitumor response: three patients had a complete response, ten patients had a partial response (greater than or equal to 50% resolution of clinical disease), and one patient had a minor response. Responders included those with Stages Ia to IVa cutaneous T cell lymphoma, and remissions have lasted at least 4 to 27.5 months. Three patients progressed from a partial to complete response with further treatment, for an overall complete response rate of 27%. Acute flu-like side effects were generally minor and transient. Malaise/fatigue, depression, anorexia, and weight loss were common chronic dose-related side effects and the most frequent reasons for dose reduction or discontinuation of drug. Leukopenia was the most common laboratory side effect and was also dose-related. Recombinant human leukocyte interferon alfa-2a is an effective and well-tolerated single-agent therapy for early and advanced cutaneous T cell lymphoma.

Thirteen patients with metastatic malignant melanoma received interferon alpha-2a (Roferon-A) and vinblastine. The interferon dosage was increased from 3 x 10(6) IU to 9 x 10(6) IU daily in 10 weeks and thereafter 9 x 10(6) IU was administered three times weekly intramuscularly. Vinblastine (0.075-0.15 mg/kg) was given every third week intravenously. One of the ten evaluable patients had partial remission (PR) (11%) for 10 months. The diseases was stabilized (NC) in three patients (30%) for 3, 6 and 9 months. Progression (PD) occurred in six patients. The treatment time varied from 5 weeks to 44 weeks. The median survival time from the beginning of this combination treatment was 5 months. The most common side-effects were fever, fatigue, loss of taste, weight loss and neutropenia. The mitogen response to phytohemagglutinin and purified protein derivative of tuberculin decreased in all patients. The response to concanavalin A decreased less and began to increase again in the patients with PR and NC. The natural killer cell activity in PD patients decreased more than in the patients with PR and NC. The ratio of T4/T8-positive cells was restored in PR + NC patients but rose in PD patients indicating a difference in the immunomodulatory effect of the combination or of the advanced disease itself on T-cell function in PD patients. This combination of daily interferon and vinblastine did not prove to be effective in melanoma. The depression of immunological functions, which was more marked in patients with PD, might indicate that vinblastine in this combination counteracts the immunostimulatory effect of interferon.

Recombinant interferon A (50 x 10(6) U/m2 three times weekly) was given to 17 patients with SCCL and 13 patients with SQL. The minimal scheduled duration of therapy was 12 weeks. Fifteen and 11 patients, respectively, were evaluable for response. All 15 patients with SCCL showed progressive disease after a period of 2.5 weeks (median; range 1-13). One patient with SQL obtained a partial remission lasting 14 months and six patients showed no change for 14-20 weeks, while the remaining patients showed progression during the initial 12 week period. Toxicity was shown to be significant and only one patient completed therapy without dose reduction. The major cause of dose reduction was fatigue and anorexia (18 patients). Fourteen patients experienced a median weight loss of 6%. Haematological and hepatological toxicity was found in six and 19 patients, respectively. In most cases parameters of marrow and liver function were reversible in spite of continuing interferon treatment.

Patients with chronic hepatitis B with active viral replication had a significantly greater fall in DNA polymerase and hepatitis-Be antigen when treated with interferon and acyclovir together than when treated with either interferon or acyclovir alone. Apart from fatigue and thrombophlebitis, tolerance of the combination therapy was excellent. The combination therapy appears the most promising for conversion of a state of active viral replication into virus latency.

Fifteen patients with metastatic malignant melanoma, including 10 who had not previously received systemic therapy, were treated with recombinant alpha2-interferon (IFN-alpha 2) in a dose of 20 million IU/m2 by 30-min i.v. infusion daily for 5 days each 14 days. Evaluable metastatic sites included lung, subcutaneous tissue, liver, nodes, adrenals, and bone. Subjective toxicity was generally mild to moderate, with fever (38.2-40.2 degrees C), occasional rigors, fatigue, myalgia, headache, and nausea. Objective toxicity included transient neutropenia and elevation of hepatic enzymes, particularly gamma-glutamyl transpeptidase. In 1 of the 10 patients receiving more than one cycle, IFN dosage was reduced because of toxicity, but later reescalated. All patients were evaluated for response. No overall partial or complete responses were observed, but two site responses (lung and subcutaneous tissue) were seen. Median survival from start of IFN treatment was 19 weeks. High doses of IFN were reasonably well tolerated in this study, but the results suggest little activity against malignant melanoma.

Eight patients were treated with leukocyte interferon for a variety of neurological malignancies that had failed or recurred after conventional therapy. Three patients with malignant astrocytoma received intratumoral interferon in dosages up to 9 million units 3X/week, with total dosages of up to 160 million units. Interferon was administered intraventricularly in 4 patients with leptomeningeal metastases and one patient with multiple brain metastases. Dosages increased from 1 to 10 million units 3X/week, and total dosages of up to 113 million units were given intraventricularly. Acute side effects of fever, nausea, vomiting, and headache occurred almost exclusively with intraventricular injections, and these subsided after the initial injection. Fatigue, loss of appetite, weight loss, and hematologic toxicity developed a few weeks after onset of treatment, independent of the dose given. A modest tumor regression was seen on CT scans of one patient with a malignant astrocytoma, who was treated with interferon for 8 months. In all 4 patients with leptomeningeal metastases, the CSF became free of malignant cells for 6 to 10 weeks, while clinical improvement was less dramatic.

Nasopharyngeal carcinoma (NPC) is a human neoplasm closely associated with Epstein-Barr virus (EBV). Human leukocyte interferon (IFN) has known antiviral and antineoplastic properties. After initial IFN treatment in one NPC patient demonstrated acceptably low toxicity, 12 additional patients were treated on a protocol with IFN, 10 X 10(6) units intramuscularly (IM) daily for 30 days. IFN did not affect serum anti-EBV antibody titers (IgA and IgG antiviral capsid and early antigens). Of six patients tested, none was found to excrete EBV in saliva before, during, or after IFN. Four patients had measurable tumor regression (two partial responses and two minor responses), three had stable disease, and five patients plus the initial preprotocol patient had progressive disease. Toxicity included fever, fatigue, and myalgias in all patients, thrombocytopenia in two patients, and neutropenia in three patients. Three patients were withdrawn from the study, one each for severe fatigue, neutropenia, and hypotension. This study demonstrates that IFN has sufficient activity in advanced NPC to justify further investigation.
