Purified recombinant human interleukin 2 (RIL 2) derived from E. coli containing the inserted gene encoding for IL 2 was administered to 20 patients with a variety of malignancies. Toxicity was dose related and included fever, chills, malaise, arthralgias, myalgias, and unexpectedly, weight gain related to marked fluid retention. All patients receiving more than 10(5) U/kg total cumulative dose developed evidence of fluid retention, and all patients requiring discontinuance of RIL 2 (11/20) received total doses of between 2.54 X 10(5) U/kg to 15.4 X 10(5) U/kg. The limiting dose with this preparation was 3000 U/kg/hr by continuous administration or 10(6) U/kg by bolus administration. IL 2 was rapidly cleared from the plasma, with a half life of 6.9 min, and a later delayed clearance was consistent with a two-compartment model, with slower release from the extravascular space back into the plasma compartment. A marked change in lymphoid cells in the periphery was noted with an early depletion of all lymphoid cells, followed by an expansion of such cells with continuous IL 2 administration. A twofold to 16-fold expansion of total lymphoid cells in the peripheral blood could be demonstrated. TAC+ cells representing up to 25% of the circulating peripheral blood mononuclear cells could be demonstrated with 3 wk of continuous RIL 2 administration. Interferon-gamma levels increased in patients treated with IL 2. Precursors of lymphokine-activated killer cells generated under standard conditions were depleted within 2 to 3 min after IL 2 administration, but repopulated the peripheral blood after 7 to 10 days of continuous IL 2 administration. No tumor regression was seen in any of the cancer patients treated with IL 2 alone.

An epidemic form of Kaposi's sarcoma associated with the acquired immune deficiency syndrome has been recently described. Seven homosexual men with biopsy-documented epidemic Kaposi's sarcoma were treated with a human interferon-gamma preparation. All patients had generalized disease. Only one patient had received prior chemotherapy, and one other patient had recovered from a prior opportunistic infection. Interferon-gamma was administered in a dose of 500,000 U intramuscularly daily, with two 10-day induction courses, separated by a 2-week medication-free period. This was followed by maintenance therapy in the same dose twice weekly. Toxicities consisted of a flu-like illness with high fevers, shaking chills, myalgias, and arthralgias. There were no complete or partial responses. All patients exhibited disease progression, with a rapid progression of previously stable disease necessitating discontinuation of therapy in three patients. We conclude that low doses of this human interferon-gamma preparation are ineffective in epidemic Kaposi's sarcoma.

Interleukin 1 alpha (IL-1 alpha) is a cytokine with pleiotropic effects, including cytotoxic-cytostatic activity against some tumor cell lines. We have conducted a phase I study of recombinant human IL-1 alpha (rhIL-1 alpha) in 17 patients with refractory malignancies to examine its toxicity and biologic activity. rhIL-1 alpha was given as a 2-h IV infusion daily for 5 days at five dose levels (0.08, 0.2, 0.8, 2.0, and 5.0 micrograms/m2). Seventeen patients with malignancies were treated, with no objective tumor responses noted. Common toxicities included: fever (100%), rigors and/or chills (96%), myalgia (54%), and headache (48%). Three patients developed grade III hypotension. The maximum tolerated dose was 2.0 micrograms/m2. rhIL-1 alpha induced a significant increase in absolute neutrophil count over baseline (p < 0.05), a delayed but significant increase in platelet count over baseline (p < 0.05), and there was a marked increase in the number of progenitors [colony-forming units (CFU)-G, CFU-M, CFU-GM, CFU-GEMM and burst-forming units (BFU-E)] observed in the peripheral blood. Nine of 12 evaluable patients showed an increase in bone marrow cellularity or myeloid:erthyroid ratio. Immunophenotyping did not demonstrate an increase in peripheral blood or bone marrow CD34+ cells. Interferon-gamma-mediated monocyte cytotoxicity (MCCTX) was significantly enhanced from baseline (p < 0.001), although an increase in direct MCCTX did not reach statistical significance. In summary, rhIL-1 alpha administration is well tolerated at a dose of 2.0 micrograms/m2 with fever, rigors, myalgia, and headache being the most frequent toxicities. Although there were no objective tumor responses, we have demonstrated significant biologic activity with increased neutrophil and platelet counts, increased peripheral blood progenitor cells, and enhanced interferon-gamma-mediated MCCTX.
