Autologous bone marrow transplantation (ABMT) for advanced hematologic malignancies is associated with high relapse rates. Interleukin-2 (IL-2) and lymphokine-activated killer (LAK) cells represent a potentially non-cross-resistant therapeutic modality that might prevent or delay relapses if used early after ABMT at a time when the tumor burden is minimal. However, high-dose chemoradiotherapy and ABMT might increase patients' susceptibility to IL-2 toxicity, and might interfere with immunologic responses to IL-2 in vivo. Therefore, to determine safety, tolerance, and immunomodulatory effects of IL-2 therapy early after ABMT, IL-2 was administered by continuous intravenous infusion to 16 patients 14 to 91 days (median, 33) after ABMT for acute leukemia, lymphoma, or multiple myeloma. Patients were sequentially assigned to escalating IL-2 "induction" doses (0.3 to 4.5 x 10(6) U/m2/d, days 1 to 5), and all patients received a nonescalating IL-2 "maintenance" dose (0.3 x 10(6) U/m2/d, days 12 to 21). Most patients exhibited mild to moderate fever, nausea, diarrhea, and/or skin rash with IL-2 infusions. The maximum tolerated "induction" dose was 3.0 x 10(6) U/m2/d; dose-limiting toxicities were hypotension and thrombocytopenia. All toxicities reversed on stopping the IL-2 infusions, and all patients completed "maintenance." Postinfusion lymphocytosis was exhibited by patients at all IL-2 dose levels. With the higher IL-2 doses, increased percentages of patients' PBMC expressed CD16 and CD56, with augmented lysis of K562 and Daudi, reflecting the induction of natural killer and circulating LAK effector activities. Increased LAK precursor activity was exhibited by patients at all IL-2 dose levels. Thus, the IL-2 therapy regimen was safely tolerated after ABMT, and pronounced immunomodulatory effects were observed with the higher IL-2 doses. These studies support the planned use of IL-2 and LAK cells after ABMT in an attempt to reduce relapses of advanced hematologic malignancies.

Recombinant interleukin-2 (rIL-2) (NSC# 600664; Hoffmann-La Roche, Inc., Nutley, NJ) was studied in a phase I clinical trial in 33 patients with advanced, measureable cancer of the colon or malignant melanoma, Eastern Cooperative Oncology Group (ECOG) performance status O-1, and no prior chemotherapy or radiotherapy. The goal of the study was to identify a dose and schedule of IL-2 to generate maximal immune modulation with tolerable toxicity. Such a regimen might allow the addition of other treatment modalities and/or prolonged treatment duration in later trials. Each patient received IL-2 as a continuous 24-hour infusion once weekly for 4 weeks and then twice weekly for 4 weeks. Five treatment groups received from 10(3) U/m2 to 3 x 10(7) U/m2 per 24-hour infusion. The maximal tolerated dose was 3 x 10(7) U/m2/d twice weekly. Patients treated twice weekly at 1 x 10(7) and 3 x 10(7) U/m2/d had immune modulation in terms of lymphocytosis, eosinophilia, increased natural killer (NK) activity, and elevated numbers of peripheral blood mononuclear cells expressing CD16, OKT10/Leu-17, and Leu-19 surface markers. Endogenous generation of peripheral blood lymphokine-activated killer (LAK) activity was demonstrated by lysis of NK-resistant Daudi targets, in patients treated at 3 x 10(7) U/m2/d. Biochemical and hematological abnormalities were moderate and reversible. Clinical toxicity included hypotension, myalgia, arthralgia, stomatitis, fever, fatigue, nausea, headache, chills, diarrhea, and oliguria at high doses. Cardiovascular toxicity was tolerable for most patients and reversed after IL-2 was stopped. Two of six melanoma patients at 3 x 10(7) U/m2/d achieved partial responses by the end of the eighth week. This IL-2 schedule appears to produce potentially clinically useful immune enhancement with tolerable toxicity.

A Phase I study of rIL-2 and levamisole was performed to evaluate the activity, toxicity, and effect on immune parameters of this combination of agents in patients with advanced malignancy. Twelve patients with advanced cancer were included and begun on therapy with rIL-2, 1 x 10(6) U/m2 subcutaneously (SQ) daily for 5 days and levamisole beginning at 25 mg/m2 orally three times daily for 5 days. The dose of levamisole was increased to 50 mg/m2 thrice daily during this study. Immune parameter analysis included the percentages of lymphocyte subsets in peripheral blood, cellular cytotoxicity assays versus K562 and Daudi cells, and lymphocyte blastogenesis to the recall antigens tetanus toxoid and Candida albicans. The dose-limiting toxicities were pruritus, nausea, and facial edema. There were no indications of significant hematologic or hepatorenal toxicities. No patient fulfilled the traditional criteria for an objective response. In 8 of 9 patients with immune parameter data available there was an increase in cellular cytotoxicity and in the percentage of lymphocytes with the natural killer phenotype (CD3-, CD16/56+). This regimen can be given as an outpatient with acceptable toxicity. For Phase II investigations the doses of rIL-2, 1 x 10(6) U/m2 SQ daily x 5 days and levamisole, 50 mg/m2 three times daily x 5 days is recommended.
