The present trial was designed to assess the feasibility of subcutaneous low-dose interleukin-2 (IL-2) given for 3 months in an outpatient setting. Twenty patients with advanced cancers (16 metastatic renal cell carcinoma) were included in this phase I study at the following three dose levels: 1, 3, and 6 x 10(6) IU/day (groups of 6, 6, and 8 patients, respectively). IL-2 was administered once daily 6 days a week for 12 weeks. Complete therapy was achieved in 13 of 20 patients, whereas 5 of 20 received at least 5 weeks of IL-2. Minor dose-dependent toxicities were observed including fatigue, transient grade 2-3 fever (11 of 18), and grade 1-2 digestive disorders (6 of 18) without significant biologic modifications but two cases of hypothyroidism. Doses were decreased from 6 to 3 x 10(6) IU/day in one patient (fever and allergic edema). All patients developed transient subcutaneous nodules at the injection sites. These side effects never required hospitalization nor discontinuation of therapy. A dose-dependent and sustained increase in peripheral blood eosinophils and lymphocytes was observed, demonstrating that subcutaneous injections in this low-dose range could have similar biologic effects to those achieved with more intensive schedules. Because it is safe, practicable, and low in cost, we conclude that s.c. low-dose IL-2 could be useful for the design of immunomodulation trials with potential new application fields.
