Proleukin (aldesleukin) has been approved for treating adult patients with metastatic melanoma.
In clinical trials of the drug, 16% of 270 patients responded to the drug with half of the patients remaining alive for four years after treatment. Proleukin produced a complete response in 6% of the 270 patients. Approximately 60% of the 17 patients who achieved a complete response have remained in remission for greater that five years without further treatment.
Adverse events reported include capillary leak syndrome, flu-like symptoms, and serious toxicities, including low blood pressure, decreased kidney and lung function, respiratory distress, cardiac abnormalities, changes in mental status and edema.
