A total of 22 patients with metastatic renal cell carcinoma or malignant melanoma were treated in a phase II study to assess the safety and efficacy of combination therapy of interleukin-2 (IL-2) and interferon-alpha (IFN-alpha). 3 x 10(6) U/m2/day recombinant human (rh)IL-2 was given in repetitive cycles by continuous 24-h infusion from day 1 to day 4; 6 x 10(6) U/m2/day rhIFN-alpha was given subcutaneously on days 1 and 4. There was one complete remission and two partial remissions in the renal cell carcinoma group and two partial remissions in the malignant melanoma group, giving an overall response rate of 24% in 21 evaluable patients with a median response duration of 5+ months. Toxicity was moderate, with hypotension, fever, chills, nausea, neurotoxicity, and dermatitis as prominent side effects. Measurement of circulating cytokine levels showed increased serum tumor necrosis factor-alpha (TNF), interferon-tau, and soluble interleukin-2 receptor levels during each cycle with a tendency to higher concentrations of TNF in responders as compared to nonresponders. With regard to therapeutic efficacy and tolerance, our approach might represent an alternative to the high-dose protocols and the labor- and cost-intensive strategies of adoptive immunotherapy.

The chemistry, biological activity, and pharmacokinetics of gamma-interferon and recombinant interferon gamma are reviewed, and the agent's clinical efficacy, adverse effects, and dosage and administration for the treatment of chronic granulomatous disease (CGD) and other disorders are described. Endogenous gamma-interferon is a 166-amino-acid protein encoded by a single gene on chromosome 12. Recombinant human interferon gamma is purified from Escherichia coli as a monomer containing 139 amino acids. Gamma-interferon has antiviral, immunomodulatory, and antiproliferative activity. Serum concentrations of recombinant interferon gamma increase in proportion to the dose. Clearance after i.m. or s.c. administration fits a two-compartment model. The half-life is 3.5-7.5 hours, and bioavailability is 89%. Evidence that recombinant interferon gamma can enhance phagocytic oxidative metabolism led to its evaluation for use in the treatment of CGD. Clinical studies showed that the agent decreases the frequency of serious infections in patients with CGD. Recombinant interferon gamma has shown only limited success in the treatment of metastatic renal cell carcinoma (RCC), both as a single agent and in combination with recombinant interferon alfa. Similarly, although interferons appear to be able to change cytogenetic abnormalities in some patients with Philadelphia chromosome-positive chronic myelogenous leukemia, therapy with recombinant interferon gamma has led to minimal success. However, the agent has produced some encouraging results in atopic dermatitis. The adverse effects of recombinant interferon gamma in patients with CGD usually consist only of fever, chills, headache, and erythema. The recommended dosage in CGD-afflicted children whose body surface area is greater than 0.5 sq m is 50 micrograms/sq m given by s.c. injection three times a week for life. Recombinant interferon gamma has given new hope to patients with CGD. Although the drug is very expensive, the cost may be offset by fewer hospitalizations to treat infection.

Fifteen patients with metastatic renal cell carcinoma (RCC) were treated by administration of autologous lymphokine-activated killer (LAK) cells given together with systemic administration of interleukin-2 (IL-2). Pulmonary metastases alone were found in 10 cases, pulmonary and mediastinal nodal metastases in 3, and pulmonary and bone metastases in 2. LAK cells, generated by incubation in 700 units/ml of IL-2 for 3-4 days, were intravenously administered once a week. In addition, beginning on the day of the first LAK cell infusion, 3.5 x 10(5) units of IL-2 were intravenously infused once or twice a day with occasional supplementation of 3.5 x 10(5) units of IL-2 on each day of LAK cell infusion. The total number of LAK cells and total amount of IL-2 administered per patient in this study ranged from 0.8 x 10(10) to 6.9 x 10(10) cells and from 10.2 x 10(6) to 74.9 x 10(6) units, respectively. As toxic effects caused by the infusion of LAK cells, headache, shaking chills, fever and leukocytosis were found in all cases. Side effects possibly induced by IL-2 infusion were tolerable fever, fluid retention (body weight gain of 2-3 kg) and eosinophilia. Out of 15 patients, a partial response was observed in 4 patients who had pulmonary metastases alone. One of the 4 patients with a partial response was clinically free of disease after undergoing a thoracotomy for resection of residual lesions, but a brain metastasis was detected 10 months after the thoracotomy. The remaining 3 patients are being closely followed up at present.(ABSTRACT TRUNCATED AT 250 WORDS)

We studied the safety, tolerance, and clinical effects of the combined administration of subcutaneous recombinant human interleukin-2 and interferon alfa-2b in 54 patients with advanced cancer, for whom no effective standard therapy was available. Treatment courses consisted of a 2-day interleukin-2 pulse (14.4-18 million units (MU) m2/day), followed by 3.6 up to 4.8 MU/m2/day, 5 days per week, over 6 consecutive weeks and interferon alfa-2b at 3 up to 6 MU/m2, administered two-three times weekly for 6 weeks. Overall, patients received more than 90% of the projected dose of interleukin-2 and interferon alfa-2b, respectively. Of 54 evaluable patients (32 renal cell cancer, 12 melanoma, eight colorectal cancer, one B-cell lymphoma, one Hodgkin's disease), four complete responses occurred in patients with renal cell carcinoma, and a greater than 50% reduction in tumour size (partial response) in six renal cell carcinoma patients and one melanoma patient. Moreover, 21 patients (13 renal carcinoma) had stable disease. The median duration of response was 19 months (range 16-22 months) in complete responders. Clinical responses were associated with a mean peripheral blood eosinophil count of more than 1,000/microL (P less than 0.05 versus non-responders). Systemic toxicities included fever, chills, nausea, anorexia, and hypotension limited to WHO grades I and II in more than 80% of patients treated. No treatment-related deaths occurred. This combination of subcutaneously administered recombinant interleukin-2 and interferon alfa-2b has significantly diminished the side effects normally observed with high-dose intravenous recombinant interleukin-2, which requires admission to hospital. It has been shown to induce objective tumour regression in out-patients with progressive metastatic renal cell carcinoma and malignant melanoma.

A 70-year-old woman was treated for renal cell carcinoma with recombinant human tumor necrosis factor, 450,000 U/m2 of body surface area, daily for 5 days, once a month. She had had psoriasis for 25 years. After two courses of recombinant human tumor necrosis factor her psoriasis resolved. A 40-year-old man with severe psoriasis was subsequently treated with a total of seven complete and incomplete 5-day courses of recombinant human tumor necrosis factor at doses of 50,000 to 300,000 U/m2/day. Significant toxicity (fever, chills, hypertension, and hypotension) was encountered. Partial resolution of the lesions was seen. Tumor necrosis factor is an active agent in psoriasis.

We have studied the safety, tolerance, and clinical effects of the combined administration of subcutaneous recombinant human interleukin-2 and alpha-interferon in 34 patients with metastatic renal cell carcinoma who had undergone tumor nephrectomy. Treatment courses consisted of a 2-day interleukin-2 pulse (14.4 to 18.0 million IU/m2/d), followed by 3.6 to 4.8 million IU/m2/d, 5 days per week, over 6 consecutive weeks, and alpha-interferon at 3.0 to 6.0 million U/m2, administered 2 to 3 times weekly for 6 weeks. Patients received more than 90% of the projected dose of interleukin-2 and alpha-interferon, respectively. Of 34 patients with metastatic progressive renal cell carcinoma in this study, four had complete response and six had greater than 50% reduction in tumor size (ie, partial response). There were, in addition, 13 patients with stable disease. So far, all complete responses have been durable, with a median duration of 23+ months. Clinical responses were associated with a mean peripheral blood eosinophil count of more than 1,000/microliters (P less than .05). The predominant toxicities included fever, chills, nausea, anorexia, and hypotension, and were limited to World Health Organization grades 1 and 2 in more than 80% of patients treated. No treatment-related deaths occurred. This combination of subcutaneously administered recombinant interleukin-2 and alpha-interferon has significantly reduced the side effects normally observed with high-dose intravenous recombinant interleukin-2. It can induce objective tumor regressions in patients with progressive metastatic renal cell carcinoma. Unlike the intravenous schedules developed by Rosenberg and West, which require admission to hospital, all the patients in this study were treated in an outpatient setting.

Patients (n = 15) with metastatic malignant melanoma, hypernephroma, and colon carcinoma received a three-phase adoptive immunotherapy protocol: phase 1, 10(5) units (high-dose) interleukin-2 (IL-2) iv every 8 h or 1 mg/m2 continuous intravenous infusion; phase 2, 6.5 d rest + leukapheresis; phase 3, 4 d of high-dose IL-2 plus three infusions of autologous lymphokine-activated killer cells. Toxicities of treatment included fever, chills, tachycardia, hypotension, vomiting, diarrhea, and fluid retention. Patients entering the trial were not malnourished, and mean plasma ascorbic acid concentrations before therapy were normal (36.3 +/- 14.2 mumol/L). Mean concentrations dropped by 80% after the first phase of treatment with high-dose IL-2 alone (to 7.4 +/- 4.5 mumol/L). Mean plasma ascorbic acid concentrations remained severely depleted (between 4.5 and 7.4 mumol/L) throughout the remainder of the 15-d treatment. Ascorbic acid concentrations became undetectable (less than 2.8 mumol/L) in 12/15 patients during this time. Blood pantothenate and plasma vitamin E concentrations remained within normal limits in all patients tested throughout the phases of therapy.

Fourteen patients with metastatic renal cell carcinoma (RCC) were treated by systemic administration of autologous lymphokine-activated killer (LAK) cells and interleukin-2 (IL-2). Pulmonary metastases alone were found in 9 cases, pulmonary and mediastinal nodal metastases in 3, and pulmonary and bone metastases in 2. LAK cells, generated by incubation in 2 units/ml of IL 2 for 3-4 days, were intravenously administered once or twice a week. In addition, beginning on the day of the first LAK cell infusion, 1000 units of IL 2 diluted in normal saline were intravenously infused once or twice a day with occasional supplementation of 1000 units of IL-2 on each day of LAK cell infusion. The total number of LAK cells and total amount of IL-2 administered per patient in this study ranged from 0.8 x 10(10) to 6.9 x 10(10) cells and from 3.3 x 10(4) to 21.4 x 10(4) units, respectively. As toxic effects caused by the infusion of LAK cells, headache, shaking chills, fever and leukocytosis were found in all 14 cases. Side effects possibly induced by IL-2 infusion were tolerable fever, fluid retention (body weight gain of 2-3 kg) and eosinophilia. No objective regression of mediastinal nodal or bone metastases was observed. In regard to lung metastases, however, partial and minor responses were observed in 3 and 2 cases, respectively. One of the 3 patients with a partial response was clinically free of disease after undergoing a thoracotomy for resection of residual lesions, but a brain metastasis was detected 10 months after the thoracotomy. The remaining 2 patients are being closely followed up at present. In 3 of 11 patients who showed a minor response, no change or progressive disease, brain metastases were observed during or after the immunotherapy. Furthermore, we examined the possibility of selection of suitable candidates for this therapy on the basis of the degree of in vitro LAK activity against autologous cultured tumor cells in 6 patients, but there was no significant correlation between in vitro autologous tumor cell lysis by LAK cells and the clinical response to immunotherapy. In conclusion, although a complete response could not be obtained, it can be said that this immunotherapy may be effective against RCC, in particular lung metastases, since a partial response was achieved in 3 of 14 patients. However, it should be taken into consideration that this immunotherapeutic approach may have a risk of increasing the frequency of brain metastases.

Clinical immunotherapy trials have been performed recently where ex vivo interleukin-2 (IL-2)-activated peripheral blood mononuclear cells (i.e., the "LAK" cells) have been transfused in addition to IL-2 infusions. In such protocols, patients have received highly heterogeneous cell suspensions and the nature of the effector cells that may have contributed to tumor regression has remained unclear. In certain animal models, it has appeared that natural killer lymphocytes were the effector cell type responsible for tumor regression. To test whether NK cells could eventually be relevant for the treatment of human tumors, we have performed a feasibility trial where purified lymphokine-activated natural killer (LANAK) cells have been prepared and transfused to a limited series of renal cell carcinoma patients receiving IL-2 (continuous infusions at 3 x 10(6) U/m2/day). Natural killer lymphocytes (1-2 x 10(6] were purified from peripheral blood mononuclear cells and expanded during 4-5 weeks in the presence of IL-2 on microtiter plates containing feeder layers cells. In vitro, the resulting LANAK cell suspensions were 100 times (range of 2 to 10(3] more efficient against Daudi target cells than their autologous LAK counterparts. Twelve patients were included; 9 received the two planned courses of treatment with LANAK cells and IL-2. Overall toxicity was relatively moderate. Besides occasional chills, there were no apparent secondary effects due to cell infusions. The mean number of LANAK cells transfused per patients was 45.1 x 10(9), ranging from 7 to 125 x 10(9). The biodistribution of LANAK cells was similar to that reported previously for LAK cells with no preferential localization to tumor sites. We conclude from this study that using well-defined populations of effector lymphocytes is a feasible cellular therapy approach that may lead to improved understanding and efficacy of the novel immunotherapy methods.

A phase II clinical trial was conducted using subcutaneous recombinant human interleukin-2 (rIL-2, EuroCetus) and subcutaneous interferon-alpha 2b (rIFN-alpha 2b, Essex) in patients with advanced cancer. Safety and tolerance of this outpatient regimen were assessed in 17 patients with progressive metastatic renal carcinoma, 14 of whom were evaluable for clinical response to combined rIL-2 and rIFN-alpha 2b. In this study, rIL-2 was administered every 12 hours, at 1.5 million (Cetus) U/m2 on days 1 and 2, followed by 0.3 million U/m2 5 days per week for 6 consecutive weeks. Concomitantly, rIFN-alpha 2b was given as 5 million U/m2 three times weekly for 6 consecutive weeks. Patients presenting with stable or regressive disease after 6 weeks of rIL-2 and rIFN-alpha 2b (11 of 14) were scheduled to repeat combination therapy. After one treatment cycle, five of 14 patients presented with partial remission; two of these patients achieved complete regression of metastatic lesions. After therapy, six patients have been in stable disease for up to 8 months. toxicity of this regimen was moderate, with local inflammation of the injection sites, grade I-II (World Health Organization criteria) fevers, chills, malaise, nausea and/or vomiting, and anorexia in 70% to 100% of patients treated. After 6 weeks of rIL-2 and rIFN-alpha 2b, laboratory evidence of treatment-related hypothyroidism and hyperthyroidism was obtained in one and four patients, respectively. Immunogenicity of sc rIL-2 was mostly limited to the development of nonneutralizing antibodies that occurred in approximately 40% of patients. None of the patients exhibited antibodies specific to rIFN-alpha 2b.
