 AB    PURPOSE: Interleukin-1 (IL-1) and IL-2 have synergistic antitumor and
       myelostimulatory activities. We investigated the clinical and biologic
       effects of IL-1/IL-2 therapy. PATIENTS AND METHODS: Twenty patients with
       metastatic cancer, divided into five cohorts, were treated with
       escalating doses of IL-1 beta (0.005 to 0.2 micrograms/kg/d)
       administered as a 30-minute intravenous (IV) infusion on days 1 to 4,
       combined with a fixed dose of IL-2 (0.1 mg/m2/d) administered by
       continuous IV infusion on days 1 to 4. The 4-day cycles were repeated
       weekly for up to 8 weeks in the absence of toxicity and/or progressive
       disease. RESULTS: Patients tolerated up to 0.2 microgram/kg/d of IL-1
       beta in combination with IL-2 without severe adverse effects.
       Peripheral-blood CD4-to-CD8 ratios and lymphokine-activated killer (LAK)
       activity were higher at the lower doses (0.005 to 0.05 microgram/kg/d)
       of IL-1 beta and higher than that of a cohort of patients treated with
       IL-2 alone. WBC counts, primarily neutrophils, increased significantly
       with higher doses of IL-1 beta (0.1 to 0.2 microgram/kg/d). Platelet
       counts were not significantly altered. Increases in serum IL-6,
       interferon gamma (IFN-gamma), and soluble IL-2 receptor levels were
       observed, but did not vary with IL-1 beta dose. Tumor regressions were
       observed in patients with colorectal cancer, melanoma, and renal cell
       carcinoma. CONCLUSION: IL-1 beta cancer be administered in combination
       with IL-2 with acceptable toxicity. Our results suggest that the
       addition of even low-dose IL-1 beta to IL-2 may be associated with
       potentially beneficial biologic activity; higher doses of IL-1 beta (0.1
       to 0.2 microgram/kg/d) may add potentially beneficial hematologic
       activity.
