Seventy patients consecutively admitted to a single institution were treated with high-dose interleukin-2 (IL-2) and analyzed for determining the incidence and risk factors associated with reactions to i.v. contrast media. Patients with metastatic renal cancer (n = 44) or melanoma (n = 26) received 74 cycles of IL-2 administered at 2 to 6 x 10(6) U/m2/d for 10-21 days either alone or with lymphokine-activated killer (LAK) cells or tumor-infiltrating lymphocytes (TILs). Seventy-four computed tomography (CT) scans were performed before administration of IL-2; and 74, 59, and 35 CT scans were performed, respectively, 2, 6, and 10 weeks after administration of IL-2. Of the 168 scans performed after therapy with IL-2, non-ionic media were used in 110 and ionic media were used in 58. There were no reactions before administration of IL-2, but there were nine reactions after therapy with IL-2. Reactions to contrast media occurred 1-4 hours after media infusion and included fever, chills, emesis, diarrhea, rash, wheezing, hypotension, edema, and oliguria. Hospitalization was required in seven cases, including intensive care unit support in four, but all patients recovered fully. Contrast reactions were more frequent 2 weeks after therapy with IL-2 (eight of 74 scans, 11%) compared with 6 weeks after IL-2 (one of 59 scans, 1.7%), but the difference was not statistically significant (McNemar's test). Six patients who reacted to contrast 2 weeks after IL-2 treatment received contrast 4 weeks later: five had no reaction and only one experienced a reaction.(ABSTRACT TRUNCATED AT 250 WORDS)

A total of 29 patients with stage IV colorectal cancer were entered into a phase II trial of bolus interleukin-2 (IL-2) and interferon-alpha (IFN alpha) (3 x 10(6) U/m2 of each cytokine given i.v. q8h x 15 doses and repeated in 2 weeks). Immunologic parameters measured on isolated peripheral blood lymphocytes revealed increased activated T cells with upregulated natural killer and lymphokine-activated killer activity. Among 24 evaluable patients, there were 4 partial responses (17%) of short duration ( < or = 6 months). Three of the responding patients had been refractory to prior chemotherapy. Overall median survival in the 24 evaluable patients was 18.5 months. Therapy necessitated an inpatient setting, with the most common toxicities being hypotension, hepatic insufficiency, fever, hypocalcemia, nausea/vomiting, and renal insufficiency. There were two treatment-related deaths. Because neither IL-2 nor IFN alpha alone has significant activity against colorectal cancer, the responses observed in this study suggest a potential synergistic effect between the two cytokines. However, the toxicity and short duration of response without survival benefit do not support the routine use of this regimen as a therapeutic modality for this tumor histology.

Because interleukin-2 (IL-2) and interferon-gamma (IFN-gamma) act synergistically in vitro in the generation of lymphokine-activated killer (LAK) cells. we initiated a clinical trial of these lymphokines in combination. Twenty patients with advanced malignancy were treated at fixed dose levels of recombinant IFN-gamma given by intramuscular (i.m.) injections once a day and recombinant IL-2 given by an intravenous (i.v.) bolus injection 3 times a day for 7 days after a 3-day treatment with fixed doses (250 micrograms/m2/day) of IFN-gamma alone. A minimum of four patients were treated at each of the four dose levels studied. The side effects of the combination therapy were similar to those seen with individual lymphokines and included fever and chills, myalgia, headache, fatigue, nausea. vomiting, peripheral edema, skin rash, and hypotension. The maximum tolerated dose for the combination after a fixed dose of IFN-gamma was 2 x 10(5) U/M2/day (10 micrograms/m2/day) of IFN-gamma and 3 x 10(6) U/M2/day of IL-2, with fluid retention as the dose-limiting toxicity. Whereas natural killer (NK) or LAK activity or both were significantly increased in four of eight patients studied, only one patient with renal cell cancer had a minor response for four treatment cycles. We conclude that combination therapy with cytokines IL-2 and IFN-gamma given in this schedule had manageable toxicity and exhibited immunomodulatory effects in some patients but had no significant antitumor activity in this patient population.

Adoptive immunotherapy (AI) with interleukin-2 (IL-2) and lymphokine-activated killer cells (LAK) is an antineoplastic modality in which immune-activated cells are administered to a host with advanced cancer in an attempt to mediate tumor regression. Levamisole (LEV), an immune stimulant, has been suggested to have therapeutic effectiveness in a variety of cancers. After a phase I trial of recombinant IL-2 plus LEV, a phase II trial of this combination was conducted in patients with advanced malignant melanoma. Nineteen patients were entered in the trial. They received IL-2 at 3 x 10(6) U/m2 subcutaneously daily x 5 plus LEV 50 mg/ m2 orally three times daily (p.o. t.i.d.) x 5. Patients were reevaluated at four-week intervals. None of the patients achieved a partial or complete regression (PR, CR). The median time to treatment failure (refusal, progression, or off study due to toxicity) was 56 days. Grade IV toxicities included vomiting (3 patients), lethargy (1 patient), and musculoskellar pain (1 patient). This regimen is not recommended for further testing in patients with advanced malignant melanoma.

Natural killer (NK) cells may be expanded in vivo with a prolonged course of daily subcutaneous interleukin-2 (IL-2). However, cellular activation requires higher concentrations of IL-2 than are achieved with low-dose therapy. The objective of the current trial was to determine the toxicity and immunological effects of periodic subcutaneous intermediate-dose IL-2 pulses in patients receiving daily low-dose therapy. A group of 19 patients were treated with daily subcutaneous low-dose IL-2 at 1.25 x 10(6) International Units (1.25 MIU) m(-2) day(-1). After 4-6 weeks, patients received escalating 3-day intermediate-dose IL-2 pulses administered as single daily subcutaneous injections, repeated at 2-week intervals. The maximum tolerated pulse dose was 15 MIU m(-2) day(-1), with transient hypotension, fatigue, and nausea/vomiting dose-limiting. Subcutaneous IL-2 resulted in in vivo expansion of CD56+ NK cells (796+/-210%) and CD56bright natural killer (NK) cells (3247+/-1382%). Expanded NK cells coexpressed CD16, and showed lymphokine-activated killer activity and antibody-dependent cellular cytotoxicity in vitro. Intermediate-dose pulsing resulted in serum IL-2 concentrations above 100 pM. Cellular activation was suggested by rapid margination of NK cells following pulsing, coincident with peak IL-2 levels, with return to baseline by 24 h. In.addition, interferon gamma production in response to lipopolysaccharide was augmented. Subcutaneous daily low-dose IL-2 with intermediate-dose pulsing is a well-tolerated outpatient regimen that results in in vivo expansion and potential activation of NK cells, with possible application in the treatment of malignancy and immunodeficiency.

High-dose continuous infusion interleukin-2 (IL-2) regimens generate a higher degree of lymphokine activated killer cell (LAK) cytotoxicity when tested against tumor cells in vitro and a higher rebound lymphocytosis in vivo than do bolus IL-2 regimens. Lymphocytes initially activated by continuous infusion IL-2 have increased cytotoxicity against cancer cells when they are subsequently pulsed with additional IL-2. Famotidine may enhance LAK cytolytic ability. Six patients with kidney cancer have been treated with a combination of famotidine 20 mg intravenous bid and continuous infusion IL-2 (18 MIU/sq m/24 hours) for 72 hours, followed by a 24-hour rest, then IL-2 18 MIU/sq m over 15-30 minutes. The most common metastatic sites were the lung, lymph node, and bone. Median number of cycles received = 5 (range, 3-8). The most common toxicities were fever, rigors, nausea/emesis, hypophosphatemia, hypotension, elevated creatinine, and metabolic acidosis. There were no treatment-related deaths, and no patients required intensive care admission. Two partial responses (33% response rate) have been seen. Median survival has not been reached at greater than 8 months. The combination of high-dose continuous infusion plus pulse IL-2 and famotidine is active in metastatic kidney cancer. An accrual of additional patients is needed to better assess the response rate.

Infusional interleukin-2 (IL-2) is able to elicit lymphokine-activated killer cell (LAK) cytotoxicity against kidney cancer in vitro and in vivo. Famotidine may be able to augment LAK cytotoxicity against neoplastic cells. Fifteen (15) patients were treated with continuous-infusion IL-2 (9-18 MIU/m2/24 hours) for 72 hours and famotidine 20 mg intravenously twice per day. Cycles were repeated every 3 weeks. These patients had a median age of 60 years (range, 29-72), had a median performance status of 1 (range, 0-1), and had metastatic sites, including lung, bone, lymph node, and liver. The most common toxicities of this regimen were hypophosphatemia, fever, nausea/emesis, rigors, elevated creatinine, and hypomagnesemia. One (1) complete and 6 partial responses have been seen (47% response rate). The median duration of response is 9 months. The median survival for all patients is 20 months. Five (5) patients are alive at a median of 36+ months. This combination of infusional IL-2 with famotidine is active in metastatic kidney cancer.

Daily short intravenous (i.v.) infusions (pulses) of interleukin-2 (IL-2) have been developed to decrease toxicity while maintaining anticancer activity of this agent against melanoma. Such IL-2 schedules have previously been shown to promote lymphokine-activated killer (LAK) cell activity. Famotidine may increase LAK activity by increasing IL-2 internalization by the IL-2 receptor on lymphocytes. We treated 16 patients with metastatic melanoma using pulse IL-2 18 (15 patients) or 9 million IU/M2 (1 patient) i.v. over 15-30 minutes preceded by famotidine 20 mg i.v. daily for 5 days on an oncology inpatient unit. Cycles were repeated every 3 weeks until disease progression. Patient characteristics were as follows: 11 males, median age, 66, median ECOG performance status, 1; common metastatic sites: lymph nodes, lungs, subcutaneous, liver, and bone. Median number of cycles received was 3. Overall, 93% of planned doses were delivered. Most common toxicities were hypomagnesemia, fever, rigors, hypophosphatemia, and nausea/emesis. Three (3) patients had partial responses (19% response rate; 95% confidence interval: 6%-44%). A fourth patient, after resection of residual disease, remains a surgical complete responder at > 12 months. Responses occurred in lung, liver, lymph nodes, bone, and subcutaneous sites. Median response duration was 7 months. Pulse IL-2 with famotidine has activity in melanoma.

High-dose interleukin-2 (IL-2), given via continuous intravenous (i.v.) infusion, induces lymphokine-activated killer (LAK) cell cytotoxicity against tumor cells. These LAKs exhibit enhanced cytotoxicity against tumor cells in vitro when they are subsequently pulsed with additional IL-2. Famotidine may increase LAK cytotoxicity against neoplastic cells by allowing for greater IL-2 uptake at the IL-2 receptor on lymphocytes. Twenty-three (23) patients received famotidine 20 mg i.v. twice per day and continuous-infusion IL-2 (18 MIU/m(2)/24 hours) for 72 hours, followed by a 24-hour rest, then 1-3 daily-pulse IL-2 doses of 18 MIU/m(2) over 15-30 minutes preceded by famotidine 20 mg i.v. Cycles were repeated every 3 weeks. The most common metastatic sites were lung, lymph node, and subcutaneous/soft tissue. The most common toxicities were fever, rigor, nausea/emesis, hypophosphatemia, hypotension, elevated creatinine, and pulmonary edema. There were no treatment-related deaths. One (1) complete (4%) and 9 partial responses (39%) were seen (43% total response rate; 95% confidence interval: 22%-65%). Median survival for all patients is 13 months. The combination of famotidine and high-dose continuous infusion + pulse IL-2 is active in metastatic melanoma.
