Chronic granulomatous disease is a group of rare x-linked or autosomal genetic disorders of the phagocytic NADPH oxidase system involved in host defence against various microorganisms. It is manifested by a common phenotype consisting of recurrent serious, life-threatening infection and granuloma formation. Following the finding that interferon gamma-1b (IFN gamma-1b) can potentiate phagocyte activity in some other disease states as well as restoring defective phagocyte NADPH oxidase system activity in at least some patients with chronic granulomatous disease, a large-scale placebo-controlled trial was undertaken with IFN gamma-1b in patients with chronic granulomatous disease. Long term treatment with a therapeutic dosage of IFN gamma-1b produced a significant reduction in the incidence of serious clinical events necessitating hospitalisation. The relative risk of serious infection and the number of days in hospital were each reduced by about two-thirds, and the mean duration of hospital stay by about one-third in those who did experience infection. The greatest therapeutic benefit was found in patients aged less than 10 years, but all patients were improved regardless of age, sex, use of prophylactic antibiotics or genetic pattern of inheritance. The drug was well tolerated with the commonest adverse effects (e.g. fever, headache, chills, injection site erythema) usually being mild, transient, and relieved by symptomatic treatment. IFN gamma-1b therefore provides an effective and well tolerated therapy for patients with chronic granulomatous disease, offering an important clinical advance in the treatment of this rare genetic disorder by improving the prognosis of its serious and life-threatening infectious sequelae.

The aim of this phase I study was to exploit the potential efficacy of an alpha-2a-interferon (alpha-2a-IFN)-subcutaneous interleukin-2 (IL-2) combination, bypassing the toxicity usually associated with bolus or continuous infusion of IL-2. Therefore, nineteen patients with metastatic malignancies (7 melanomas, 6 renal cell carcinomas and 6 soft tissue sarcomas) were treated according to a dose escalating schedule of subcutaneous IL-2 combined with intramuscular alpha-2a-IFN for 5 days/week for 3 consecutive weeks. Cycles were repeated every 2-4 weeks unless disease progressed. Alpha-2a-IFN (3 MU/die) was given continuously, including during the rest weeks. IL-2 doses were started at 2 MIU/day/sqm and the MTD of 6 MIU/day/sqm was progressively reached. The dose of IL-2 was given twice daily every 12 hours. Both of the cytokines were administered in an outpatient setting. The main side effects were fever, chills, fatigue, hypotension, nausea and vomiting. Toxicity was correlated with IL-2 dose level. It was found to be mild at 2 and 4 MIU/day/sqm, while, in contrast, grade III toxicity was observed only at the highest dose of 6 MIU/day/sqm. However, this grade III toxicity was manageable and did not prevent continuation of the treatment as long as the dose was not increased above 6 MIU/day/sqm. Three patients, one with melanoma and two with renal cell carcinomas, obtained clinical partial responses. In eight patients, stable disease, and in the remaining eight, progression, were observed. The data suggest that the combined use of the two BRMs has manageable side effects and would seem to be efficacious. A phase II study at the recommended dose of 6 MIU/day is now necessary.

Interleukin-2 (IL-2)-based immunotherapy regimens are accompanied by dose-limiting toxicity consisting of fever, tachycardia, chills and capillary leak syndrome. We hypothesized that the toxicity was caused by the induction and release of endogenous cytokines such as tumor necrosis factor alpha (TNF alpha) and interferon gamma (IFN gamma). We measured the serum levels of TNF alpha and IFN gamma in IL-2-treated melanoma patients and attempted a correlation with clinical toxicity. A total of 23 patients received either 6 x 10(6) IU or 12 x 10(6) IU Cetus IL-2/m2 by i.v. bolus daily for 5 consecutive days on weeks 1, 3 and 5. Serum TNF alpha and IFN gamma levels were measured by enzyme-linked immunosorbent assay. Clinical toxicity was scored each day by objective measurements of hypotension, tachycardia, fever and chills/rigors. Clinical toxicity and IFN gamma levels correlated nicely, peaking on the 5th day of each treatment cycle. The kinetics and magnitude of TNF alpha production, however, were not predictable and did not correlate with either IFN gamma or toxicity. Some patients had modest increases in TNF alpha production while others had markedly increased levels during the second and third treatment weeks. Remarkably, these high levels persisted during nontreatment weeks and after completion of therapy. This clinical study demonstrates novel kinetics for immunoreactive TNF alpha in IL-2 cancer patients, which do not correlate well with toxicity.

A multicentre study of IL2 and IFN alpha has been performed in 58 patients with metastatic melanoma. The scheme consisted of IL2 3.0 BRMP MU/m2/d as a continuous infusion for 4 d combined with subcutaneous administration of IFN alpha 6 MU/m2/d, day 1 + 4. The cycle was repeated every 2 weeks for a maximum duration of 26 weeks. 54 patients were evaluable for response. One (2%) achieved a complete and 10 (19%) a partial response. 19 (35%) patients were stable and 24 (44%) showed progressive disease. Common side-effects included fever, chills, fatigue, skin rash, anorexia, nausea and diarrhoea. Hypothyroidism was noted in 10% of the patients. These results show that this regimen of IL2 and IFN alpha is active but, in contrast to what could be expected, not superior to IL2 alone possibly due to suboptimal dosing. In an ongoing study in Rotterdam and Nijmegen, a more intense schedule was chosen, consisting of three daily i.v. doses of IL2 4.5 BRMP MU/m2 and IFN alpha 3.0 MU/m2 for 5 d. This regimen is repeated at intervals of 3 weeks for a total of three cycles. Presently, nine patients have been entered. One patient achieved a complete response, four a partial response (overall 56%), three had stable disease and one progressed. Toxicity was severe and treatment was prematurely stopped in five patients: myocardial infarction (one patient), atrial fibrillation (one patient), negative T waves and myocardial hypokinesia (one patient) and psychosis (two patients). This regimen can only be justified if the therapeutic results are superb, which has yet to be awaited.

The safety, tolerance, and clinical effects of a home therapy regimen of recombinant human interleukin-2 (rIL-2) and interferon-alpha 2b (IFN-alpha 2b) self injected subcutaneously have been assessed in 35 patients with advanced cancer refractory to standard therapy. 52 treatment cycles were given, each consisting of a 2-day rIL-2 pulse of 9.0 million IU/m2 every 12 h, followed by 6 weeks of rIL-2 1.8 million IU/m2 twice daily for 5 days per week and of IFN-alpha 2b 5.0 million U/m2 thrice a week. The main adverse effects were fever, chills, nausea, anorexia, and hypotension and were limited to WHO grades of severity I and II in 29 of 35 patients. No treatment-related deaths occurred. The response rates among patients with renal-cell carcinoma were similar to those reported for high-dose intravenous regimens of interleukin-2 that are toxic and have to be given in hospital.

A total of 29 patients with advanced malignancy were treated with recombinant interferon gamma (rIFN gamma, specific activity = 2.10(7) units/mg, purity greater than 95%) given by intravenous bolus at doses escalating from 0.01 mg/m2 to 5 mg/m2 (2 x 10(5) - 10(8) IU/m2) in nine successive steps (at least 3 patients/step). Injections of rIFN gamma were repeated every 72 h for 15 days. Toxicity was evaluated according to the WHO scale. Fever and chills occurred in all patients treated without clear dose effect. Nausea and vomiting appeared at the fifth dose level and their frequency seemed to be dose-related. Cardiovascular side-effects (first-degree atrioventricular reversible block) were observed at the 2 mg/m2 and 5 mg/m2 levels (3 patients). Hematological toxicities were mild (2 grade 1 and 1 grade II cases of granulocytopenia). Minor biological modifications included a transitory rise in hepatic enzymes (12 patients), which correlated with the presence of liver metastasis. Hypocholesterolemia was observed in 18 patients. The appearance of antibodies against rIFN gamma was not detected. One partial clinical response was observed in a patient receiving 2 mg/m2. During rIFN gamma therapy this patient had the highest scores in this series for peripheral T lymphocytes with an activated phenotype (HLA DR+, TAC+) = 15% and for natural killer (NK) cells (NKH1, Leu19+) = 17%. rIFN gamma appears as a well-tolerated and promising therapeutic agent with toxicities and mode of action probably distinct from IFN alpha and beta.

Human neuroblastoma cells lack HLA-A,-B,-C molecules which can be induced in vitro by gamma interferon (gamma IFN). To test the hypothesis that the same induction would occur in vivo leading to tumor regression, a Phase I study was initiated. Seven patients with neuroblastoma were entered on a Phase I study of recombinant gamma IFN in children. Three received 0.05 mg/m2 intravenously (IV) three times a week, three received 0.1 mg/m2 for 4 weeks, and one patient withdrew from study before receiving adequate treatment for evaluation. No significant clinical response was seen. The side effects were fever and chills, and no serious toxicity occurred. Natural killer (NK) and lymphocyte activated killer (LAK) precursor activity of peripheral blood mononuclear cells was determined before and during treatment, and expression of HLA-A,B,C molecules was looked for on the tumor cells in the bone marrow of five patients. The NK activity initially low, reached control levels in six patients, but the increase was transient. The LAK precursor activity remained normal. Expression of HLA-A,B,C, initially absent, was induced on the neuroblastoma cells in four of six patients.

Recombinant interferon-gamma (rIFN-gamma) was given to patients with malignancies by continuous daily administration or by intermittent high doses. Local administration was performed for patients with skin malignancy, and bladder and hepatic carcinoma. Among 239 cases eligible for evaluation (144 cases treated by systemic administration and 95 cases by local injection), complete response was observed in one case each of renal cell carcinoma, malignant lymphoma and mycosis fungoides, all treated by systemic administration. Intermittent high doses of rIFN-gamma induced a response rate of 21.4% in renal cell carcinoma. This rate was higher than the 8.6% obtained following continuous administration. Average response rate to local injection of rIFN-gamma in skin malignancies was 55.3%. This value was comparable with that obtained by IFN-alpha treatment. Fever was observed in 89% of the cases treated by systemic administration. Chills, malaise and anorexia were the main side effects. Local injection also induced similar side effects, although the incidence was lower in comparison with systemic administration. Incidence of side effects was higher in the intermittent high-dose group than in the continuous administration group for all items except fever. However, patients showed good tolerance to high doses of rIFN-gamma reaching 40 X 10(6) U/m2/day.

Interferon gamma (IFN-gamma) is a lymphokine with potent in vitro effects on cell growth and immune function. We have investigated the effects of rIFN-gamma (sp act approximately 2 X 10(7) U/mg, purity greater than 99%) in 16 evaluable patients with advanced malignancy in a phase 1 trial. Patients were treated with six-hour intravenous (IV) infusions daily, five days a week for 2 weeks. After a 2-week rest period, the IV treatment cycle was repeated. Responders were maintained on repeated IV treatment cycles or daily intramuscular (IM) injections. Patients were entered at fixed dose levels of 0.1, 0.5, or 1.0 mg/m2/d. The maximum safely tolerated dose was 0.5 mg/m2. The most common side effects were constitutional symptoms, including fever, chills, fatigue, and myalgias. Reversible and transient increases in hepatic transaminase and decrease in granulocyte counts were seen. Treatment was associated with a dose-dependent increase in serum levels of beta 2 microglobulin. Partial responses (PRs) were observed in one patient with Hodgkin's disease and one patient with chronic lymphocytic leukemia. Fairly constant levels of serum IFN were found at four and six hours during infusion, followed by a rapid decline within one to two hours. We conclude that rIFN-gamma can be safely administered by a six-hour IV infusion and that it can induce in vivo some of the biologic effects reported in in vitro studies.

Combinations of interferon-alpha and interferon-gamma demonstrate synergistic antiviral and anti-proliferative activity in vitro. Therefore, we initiated a clinical study of combination interferon therapy in humans. Eighteen patients with metastatic solid tumors received daily intramuscular (IM) injections of recombinant interferon-alpha-A (IFN alfa-2a, Roferon-A; Hoffman-LaRoche, Nutley, NJ) and recombinant IFN-gamma (rIFN-gamma) for 6 weeks. The dose levels were 0.5, 1.0, 2.0, and 5.0 X 10(6) U/m2/d of each interferon. A minimum of two patients were entered sequentially at each dose level. Fever, chills, fatigue, and a greater than or equal to 50% drop in granulocyte counts were observed at all doses. Severity of symptoms corresponded to increasing dose levels. In contrast to the tachyphylaxis to these symptoms that usually develops in patients treated with the individual interferons, many patients on this study experienced persistent fever and worsening fatigue over 6 weeks. The maximum tolerated dose was 1 X 10(6) U/m2/d of each interferon. One patient with renal-cell carcinoma achieved a partial remission (duration, 3 months). Enzyme-linked immunoassay analysis in all four patients for whom complete data were available revealed that peak blood levels of IFN alfa-2a on day 22 were about tenfold higher than on day 1. Because of the possibility of cumulative toxicity, the recommended starting dose for further studies is 0.5 X 10(6) U/m2/d of each interferon, with escalation to 1.0 X 10(6) U/m2/d after 1 month if tolerance is acceptable. Phase II investigations to explore the antitumor efficacy of this regimen are planned.
