Patients with genital herpes were treated three times weekly for 12 weeks with 3 X 10(6) IU of alpha 2b interferon (20 patients) or placebo (17 patients) administered by subcutaneous injection in a double-blind trial. Interferon had minimal effects on the suppression of recurrences and moderate toxicity (chills, fever, fatigue, and leukopenia), suggesting that this route and dosage of interferon may not be clinically useful for this indication.

Twelve patients with advanced malignant disease were entered onto a Phase I study of escalating doses of beta-interferon serine given by 4-h i.v. infusion twice a wk. Three patients each were entered at starting doses of 0.01, 1, 10, and 30 million units (MU)/m2. Doses escalation within individual patients was allowed to a maximum dose of 400 MU/m2. Fever, chills, fatigue, and acral cyanosis were commonly seen and increased in frequency at higher doses. Myalgia, nausea, diarrhea, headache, and confusion were seen at lesser frequencies. Mild leukopenia, paresthesia, infusion site erythema, and hypotension were each seen in one patient. No conventional maximal tolerated dose could be defined, since several patients underwent escalation to the highest allowable dose and seemed to develop tolerance to acute toxicities. However, a maximal starting dose of 10 MU/m2 was identified, such that those begun at this level or below tolerated semiweekly dose escalation, while those begun at 30 MU/m2 could not tolerate continued therapy. Detectable serum interferon levels were noted during treatment at 10 and 30 MU/m2, the levels at which significant toxicity also first appeared. A maximal starting dose of 10 MU/m2, with gradual escalation as tolerance to side effects develops, is suggested if therapy with high-dose beta-interferon serine is given by 4-h infusion.

The efficacy and tolerance of recombinant leukocyte A interferon (interferon alpha-2a) in 30 patients with metastasized malignant melanoma in clinical stages III and IV were tested in a phase II study. During the first 10 weeks, the patients received 18 X 10(6) IU interferon alpha-2a i.m. daily and afterwards the same dose three times a week for a further four months. In 21 patients, the tumor growth was progressive. In six patients in clinical stage IV, there was a standstill for at least two months, and in three patients in clinical stage III, there was complete remission lasting between 12 and 16 months so far. The side effects of therapy differed in the individual patients. Fever, chills, limb pain, tiredness, nausea and lack of appetite were observed most often. All these symptoms as well as the frequently occurring leukopenia and elevation of the transaminases were especially pronounced at the beginning of therapy. They were dose-dependent, but reversible.

Twelve homosexual patients with Kaposi's sarcoma associated with the acquired immune deficiency syndrome (AIDS) were treated with a preparation of purified human lymphoblastoid interferon (Wellferon [Burroughs Wellcome, Research Triangle Park, NC]). They were given a dose of 20 X 10(6) U/m2 intramuscularly daily for approximately two months. Responders continued their treatment on a maintenance schedule of 20 X 10(6) U/m2 three times a week. Four patients experienced complete remissions, and four experienced partial remissions that resulted in a total response rate of 67%. The median duration of treatment was 14 weeks (7 to 28+ weeks), and the median response duration was 28+ weeks (19 to 29+ weeks). Of the four patients in complete remission, one relapsed at 25 weeks and one at 26 weeks; the other two remained in complete remission at 28 and 29+ weeks. The clinical toxicity consisted of chills, fever, fatigue, and asthenia. Hematologic toxicity was similar to that previously described for other preparations of alpha-interferon and consisted of moderate leukopenia and thrombocytopenia. Asthenia, a condition present in all 12 patients, was severe in 50%. A minimal tumor burden, the absence of circulating interferon before treatment, and a performance status of greater than or equal to 90% on the Karnofsky scale were related to an improved response rate. Measurement of immunologic parameters showed significant declines in the already impaired T cell levels, lymphocyte blastogenic response to concanavalin A, monocyte-mediated antibody-dependent cellular cytotoxicity, and monocyte-adherence. Activation of natural killer cells was not noted, and no life-threatening infections occurred during treatment. These data suggest that human lymphoblastoid interferon is an active agent in the treatment of Kaposi's sarcoma, and its use warrants further study in a larger number of patients.

Eighteen patients with advanced metastatic gastrointestinal cancer (stomach cancer 7, liver cancer 9, pancreas cancer 2) were treated with human recombinant interferon alpha-2 at doses of 3.0 X 10(6)-10.0 X 10(6) IU/body i.m. daily or every second day, 30 X 10(6) IU/body for five consecutive days every four weeks, or 30 X 10(6) IU/body once weekly. No tumor response was demonstrated in any of our cases. Among fifteen evaluable cases, nine had stabilization of evaluable disease at four weeks, but six showed progressive disease. On the other hand, fever, chills, fatigue, anorexia, nausea and vomiting were pronounced. In two cases, CNS toxicities developed. In some instances, leukopenia, thrombocytopenia, decrease of hemoglobin content and elevation of transaminase were observed. According to these findings, single use of recombinant interferon alpha-2 at the dose schedule outlined above does not seem to be of use for the treatment of advanced gastrointestinal cancer.

Recombinant interferon alpha-2 (Sch 30500) was administered to 29 patients with advanced gynecological cancers (14 patients with cancer of the cervix, 8 with ovarian cancer, 4 with uterine sarcoma, 2 with endometrial cancer and 1 with unclassified cancer). No antitumor effects (CR and PR) were noted in 23 evaluable patients. Side effects observed were fever, tachycardia, diarrhea, chills, general fatigue, anorexia, nausea and vomiting. In some patients, leukopenia, decrease of hemoglobin and elevation of SGOT and SGPT were observed. No production of antibody for Sch 30500 was noted.

We report a clinical study of the pharmacokinetics, toxicity, and biological activity of i.v.- and i.m.-administered recombinant gamma-interferon (rIFN-gamma) consisting of 143 amino acids. Ten patients with metastatic cancer were given rIFN-gamma at doses of 0.01 to 2.5 mg/sq m by alternating i.m. and i.v. bolus injections with a minimum intervening period of 72 h. After i.v. administration, rIFN-gamma was cleared monoexponentially with a short half-life of 25 to 35 min as determined by bioassay and enzyme immunoassay. After i.m. injection, a longer half-life of 227 to 462 min was measured by enzyme immunoassay. Serum titers were detected by bioassay only at high doses, suggesting partial loss of antiviral activity at the i.m. site. However, other biological effects were retained as evidenced by fever, chills, and fatigue after both routes of administration and granulocytopenia after i.m., but not i.v., doses. Two of ten patients showed objective evidence of tumor regression. These data suggest that further studies with i.m. as well as prolonged i.v. infusions of rIFN-gamma are indicated.

A total of 11 patients were treated on an escalating, single dose trial of recombinant gamma interferon (rIFN-gamma), 6 patients by the i.m. and 5 patients by the i.v. route of administration. Dose ranges within each individual were from 0.05 mg/m2 of IFN (1 mg greater than or equal to 10 X 10(6) units of IFN) escalating to 10 mg/m2. All dosages were delivered twice weekly and the i.v. dose was infused over 5 min. The most common toxicities encountered included fever, chills, fatigue, anorexia, and granulocytopenia. The influenza-like symptoms were very similar to those encountered with IFN-alpha but were generally less severe. The granulocytopenia was dose-related and transient with recovery generally seen within 48-72 h following administration of rIFN-gamma. Absolute granulocyte counts only rarely dropped below 1000 mm3. Hepatotoxicity was not observed. IFN levels were determined by both a bioassay and an enzyme-linked immunosorbent assay. By the i.v. route, the peak level of IFN activity could usually be seen at completion of the infusion with a serum half-life of 30 min. By the i.m. route, the peak level of serum activity was generally detected between 4-8 h with a serum half-life of 4.5 h after the initial elimination phase. Peak IFN levels appeared to correlate with maximum toxicity. One patient with melanoma had a 25% reduction in a cutaneous lesion, but there were no other minimal, partial, or complete responses.

Nine patients with chronic type B hepatitis were entered into a preliminary study of recombinant, human alpha-interferon therapy. Patients received one to four courses of interferon, each consisting of a fixed dose of 18, 36, 50, 68, or 100 million units given three times a week for 2 wk. Side effects including fever, chills, fatigue, myalgias, headache, and neutropenia were common and especially severe with higher doses. Serum hepatitis B virus DNA polymerase activity fell during therapy to 15%-30% of the pretreatment levels irrespective of interferon dose, but rose to the initial level by 10 days after the course ended. During follow-up, 2 patients had a sustained clinical remission in which hepatitis B virus DNA, DNA polymerase, and hepatitis B e antigen disappeared from serum and amino-transferase activities fell to normal. One patient became hepatitis B surface antigen negative. We conclude that higher doses (50 and 68 million units) of interferon have greater side effects than lower doses (18 and 36 million units), without having any greater antiviral efficacy. Further studies should be directed at therapy with lower doses given over longer periods.

Recombinant interferon alfa-2a (Roferon-A, Hoffmann-La Roche Inc., Nutley, NJ) has been evaluated in clinical trials of more than 1300 patients with a broad spectrum of oncologic disease. Patients with either solid tumors or hematologic malignancies were treated with daily or three-times-weekly intramuscular injections for induction periods ranging from 8 to 16 weeks. Doses ranged from 1 X 10(6) units to 124 X 10(6) units per injection. When administered in low daily doses (approximately 3 X 10(6) units), Roferon-A was well tolerated, and dose attenuation was rarely required. Change to three-times-weekly treatment regimen at the same dose was usually sufficient to control toxicity when it occurred in this group of low-dose patients. Those patients receiving higher doses frequently required dose attenuation to 50% of the starting dose to improve clinical tolerance. Virtually all patients treated with Roferon-A experienced some degree of acute toxicity manifested as fever, chills, myalgia, and/or headache. These reactions usually occurred with initial dosing and frequently improved spontaneously with continued administration of the drug. Acetaminophen pretreatment was generally useful in ameliorating these symptoms. Common adverse experiences occurring after repeated dosing included fatigue, anorexia, and weight loss. Serious adverse reactions including cardiovascular and neurologic toxicity have occurred infrequently, primarily at higher doses. Hematologic toxicity and elevations in liver function parameters were also observed, but rarely required dose attenuation. Adverse effects were usually reversible after dose reduction or discontinuation of therapy. Approximately 27% of all patients developed antibodies to rHuIFN-alpha 2A during treatment. No adverse clinical sequelae have been associated with antibody development to date.
