Twenty-seven patients with non-reticuloendothelial malignancies were treated with a single intramuscular injection of recombinant leukocyte alpha 2 interferon (rIFN) to assess clinical tolerance and define a maximum tolerated dose. A single patient in each of six increasing dosage groups (0.3 X 10(6) IU, 1 X 10(6) IU, 3 X 10(6) IU, 10 X 10(6) IU, 30 X 10(6) IU, 100 X 10(6) IU) received a low dose (0.01 X 10(6) IU) and served as a control for subjective and objective toxicity measurements. Severe fatigue proved dose-limiting at 100 X 10(6) IU, and all dosages above 3.0 X 10(6) IU produced one or more signs or symptoms, which typically resembled a 'flu-like' syndrome. Objective toxicity was mild to moderate (leukopenia, thrombopenia) and no toxicities were found not already known from work with interferon obtained directly from leukocytes. Evidence of an antitumor effect was apparent in 3/19 evaluable patients.

Thirty-three patients with renal cancer began treatment with human lymphoblastoid interferon (Wellferon) between August 1982 and February 1983. Interferon was administered as an i.m. injection at a dose of 5 X 10(6) units/sq m 3 times per week. Treatments were continued for at least 24 weeks in the absence of rapid disease progression or intolerable toxicity. Five patients demonstrated partial responses, which continued in two patients with durations of 239+ and 300+ days. Prolonged therapy was often required with a mean time to response of 99 days (22 to 190 days). Toxicity was substantial. Fever, chills, arthralgias, and myalgias occurred following most doses, but usually were well tolerated. Leukopenia and hepatic enzyme elevations were usually modest and always reversible. Dose-limiting side effects were progressive fatigue and anorexia which reversed within approximately 4 to 6 weeks after cessation of interferon therapy. There was no correlation between interferon levels, clinical toxicities, and response in this group of patients. We conclude that interferon has definite antitumor activity in renal cancer when given by this dose and schedule.

Twenty-one patients with advanced measurable colorectal carcinoma were treated with interferon (rIFN-alpha A) intramuscularly at 50 X 10(6) units/m2 thrice weekly. No patient had received chemotherapy for metastatic or recurrent disease. The average age of the patients was 60 years, and the mean initial performance status was 85 (Karnofsky scale). Nineteen patients were evaluable for response. One patient showed complete resolution of pulmonary nodules and stable liver metastases after 3 months of therapy. The other 18 patients developed progressive disease after 1-3 months of treatment. Toxicity was substantial but manageable; fevers, chills, fatigue, elevated serum glutamic-oxaloacetic transaminase, anemia, and mild leukopenia were common. rIFN-alpha A is minimally active against metastatic colorectal carcinoma.

Twenty-one patients with metastatic colorectal cancer were treated with high-dose intravenous interferon alpha-2 (30-50 X 10(6) units/m2) administered daily for 5 consecutive days. Courses of therapy were repeated every 2 to 3 weeks. No tumor responses were seen among 15 evaluable patients. In two subjects, disease remained stable for 3 and 7 months, respectively. Toxicity was substantial and a de-escalation of dose was frequently required. Fevers, gastrointestinal symptoms, fatigue, leukopenia, and elevated serum transaminases were common. High-dose interferon was found to be ineffective in the treatment of metastatic colorectal cancer. A daily dose of 50 X 10(6) units/m2 was greater than the maximum tolerated dose in this group of patients.

Observations of 12 patients with AIDS at this institution from March 1981 to April 1984 are reported. Ten patients were homosexuals and two were bisexual. The majority had travelled abroad (USA, Haiti) and reported multiple anonymous sexual contracts. Eleven patients reported symptoms and signs, of 2-12 months' duration, frequently seen in pre-AIDS: fatigue (10), weight loss (10), diarrhea (7), night sweats (5), fever (4), and generalized lymphadenopathy (1). Laboratory studies showed anemia (10), lymphopenia (9), leukopenia (7), decreased T-helper/T-suppressor ratio (10) and cutaneous anergy to multiple skin-test antigens (9). P. carinii pneumonia was diagnosed in three patients, P. carinii pneumonia and Kaposi's sarcoma in one patient and Kaposi's sarcoma in six patients. Another patient had a chronic mucocutaneous infection with herpes simplex and another an intestinal cryptosporidiosis and Kaposi's sarcoma. Alpha-A-interferon was used to treat patients with Kaposi's sarcoma and three patients with limited disease showed a favorable response. Six patients with advanced disease died.

A single rising dose tolerance trial of rDNA interferon-alpha 2 (IFN-alpha 2) was conducted in eight patients with the diagnoses of non-Hodgkin's lymphoma (NHL), multiple myeloma, and chronic lymphocytic leukemia (CLL). Patients received a total of six i.m. doses at weekly intervals as follows: 1, 3, 10, 30, 60, and 100 x 10(6) IU. Patients were monitored at each dose level for serum IFN activity, anti-IFN antibodies, immunomodulation, clinical toxicity, and response. All patients exhibited clinical toxicity, including fever, chills, fatigue, headache, anorexia, mild-to-moderate leukopenia, nausea, and vomiting. Toxicity was dose-related, with significant side effects occurring in all patients at levels of 10 x 10(6) IU and above and some evidence of tachyphylaxis at higher doses. All side effects, including leukopenia and thrombocytopenia, were of short duration and were resolved within 3-5 days. Fevers, rigors, myalgias, and fatigue were partially alleviated by premedication with acetaminophen or hydrocortisone. Pharmacokinetic data indicated mean peak serum IFN titers greater than 90 at a dose of 10 x 10(6) IU and greater than or equal to 200 at doses greater than or equal to 30 x 10(6) IU 8 h after injection. No anti-IFN antibodies were detected. However, the serum levels achieved at higher doses were not linear, possibly indicating in vivo degradation. Total T cells, B cells, monocytes, and T subsets monitored by flow cytometry with monoclonal antibodies remained essentially constant throughout the trial. Although some patients demonstrated minor augmentations of antibody-dependent cellular cytotoxicity (ADCC) and natural killing (NK) activity at the lowest IFN-alpha 2 doses, the majority of patients demonstrated decreases in NK activity after higher IFN doses. No correlation between immunomodulation and clinical response to IFN was observed. At higher dose levels, the predominant immunomodulatory effect of IFN-alpha 2 was suppression of NK, ADCC, and blastogenic responses to T-cell mitogens and recall antigens. B-cell functional deficits as well as radioresistant T-helper and radiosensitive T-suppressor function assessed in a pokeweed mitogen-driven immunoglobulin secretion assay appeared unaffected by IFN administration. One myeloma patient showed progression and was discontinued after 60 x 10(6) IU. There were four patients (3 NHL, 1 myeloma) who achieved partial remission (greater than or equal to 50% tumor reduction) and three (1 CLL, 2 NHL) who showed objective tumor responses of less than 50%. These data suggest that rDNA IFN-alpha 2 is well-tolerated and may have significant antitumor activity against lymphoproliferative malignancies. Clin

A case of hyperthyroidism associated with pancytopenia has been reported. A 51-year-old woman was hospitalized for the investigation of struma, peripheral edema and fatigue. Hormonal studies revealed hyperfunction of the thyroid gland. Hematological examinations showed normocytic normochromic anemia, leukopenia and thrombocytopenia with hyperplastic bone marrow and increased serum iron levels. Elevations of the anti-thyroidal antibody and anti-microsomal antibody, and a decrease in CH50 titer were observed. A Coombs' test and anti-leukocytic antibody and anti-thrombocytic antibody tests were negative. The numbers of erythrocyte and thrombocyte were normalized after the administration of methimazole for three months as were the findings of the bone marrow and the serum iron level. However, leukopenia was maintained due to the effect of methimazole. It should be suggested that the etiology of pancytopenia might be due to hyperthyroidism. Although the mechanism of pancytopenia in a patient with hyperthyroidism is unclear, it might be related to the reduced life-span of whole blood components and/or partially to the autoimmune mechanism.

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.

This paper over-viewed the clinical studies on various interferons including HLBI (human lymphoblastoid interferon), HuIFN-beta (human fibroblast interferon) and r-IFN-alpha A (recombinant leukocyte A interferon) which have been tried widely in Japan. These interferons have shown some antitumor effects on various malignancies such as malignant lymphoma, multiple myeloma, renal cell carcinoma, leukemias, brain tumors, malignant melanoma, mycosis fungoides and others. Adverse reactions included fever, general fatigue, leukopenia and thrombocytopenia, and abnormal liver function tests were experienced.

Eighty-one patients with a variety of refractory disseminated malignant neoplasms have been treated in the first multiple fixed-dose phase I trial of recombinant leukocyte A interferon (IFL-rA). Each patient received IFL-rA by intramuscular injection, three times weekly for 28 days. Dosages were escalated in different patients from 1 to 136 x 10(6) units per injection. The toxic reactions seen with IFL-rA resembled those of nonrecombinant leukocyte interferon and included fever, chills, fatigue, anorexia, myalgia, headache, occasional nausea and vomiting, and dose-dependent reversible leukopenia and hepatic transaminase elevations. The pharmacokinetics of IFL-rA were also comparable with nonrecombinant leukocyte interferon. Objective evidence of antitumor activity was seen in non-Hodgkin's lymphoma, chronic lymphocytic leukemia, Hodgkin's disease, breast cancer, and melanoma, indicating that IFL-rA, the first genetically engineered biological response modifier available for testing in cancer patients, is biologically active in vivo.
