[High-dose Roncoleukin in patients with disseminated cutaneous melanoma: a phase 1 study].
High doses of recombinant interleukin-2 (rlL-2) have been shown to provide clinical effect and long-term survival in patients with malignant melanoma. We have performed a phase 1 study of rIL-2 "Roncoleukin", produced in Saccharomyces cerevisiae. Twenty six patients with disseminated malignant melanoma received from 12 up to 108 millions international units (MIU) of IL-2 as 3-hour i.v. infusions days 1-5 of the 21-day cycle. From 2 to 6 patients were included on each dose level. Response was assessed according to RECIST criteria. Twenty two patients were available for response and 26 for toxicity; 68 cycles of therapy performed. No grade 4 toxicity or toxic death occurred. Main dose limiting toxicity was cardiologic, skin and constitutional (fever) symptoms. One hundred and eight MIU of "Roncoleukin" was considered the highest tolerable dose because of grade 3 toxicity in 2/2 patients, receiving this dose. One complete response (CR) and 2 partial responses (PR) were observed at dose levels of 72 MIU (1 CR and 1 PR) and 84 MIU (1 PR). 3/4 objective responses were in patients with metastases in soft tissues and lymph nodes. Overall response rate was 13.7%. "Roncoleukin" provide certain efficiency in patients with malignant melanoma. This drug has acceptable toxicity; the maximum tolerable dose is 108 MIU. Recommended dose for phase 2 clinical trails is 72 MIU.
