A Phase I Study of a Continuous Intravenous Infusion of Recombinant Human Interleukin IL-15 (rhIL-15) in Adults With Metastatic Cancers

Detailed Summary

Background: \- People with cancer can have a weak immune system as a result of the cancer itself, or from prior treatments. Still, treatments that stimulate the immune system have been shown to be effective against a number of different cancers. Recombinant human interleukin-15 (rhIL-15) is a drug that is designed to boost the immune system. Researchers are interested in seeing if rhIL-15 can strengthen the immune system's response against cancer. The drug will be given through a vein without a break for 10 days (240 hours). Objectives: * To see rhIL-15 given as a continuous infusion over 10 days can be used to treat advanced cancer * Identify the side effects associated with this treatment. Eligibility: \- Individuals at least 18 years of age with advanced cancer for which there are no effective treatments. Design: * Participants screening procedures will include a physical exam and medical history, laboratory (blood) tests and x-rays (Imaging studies) to determine suitability for the protocol. * Appropriate participants with easily accessible tumor deposits may also be asked to have one pretreatment and one post (cycle 1) treatment tumor biopsy. * Eligible participants will be admitted to the hospital for the rhIL-15 treatment and will spend about 12 days in the hospital. * Participants will receive one 10 day infusion each cycle (about every 42 days) for as long as there are no serious side effects and the disease does not progress. * Participants will continue treatment as long as imaging studies show that the tumor continues to shrink or for two additional cycles after it has disappeared from the x-rays to make that the cancer is completely gone. * Participants who stop treatment for side effects or because their tumor did not shrink or stopped responding to the treatment will continue to have follow-up visits to monitor the outcome of the rhIL-15 treatment until there is evidence their cancer has progress or they begin another treatment.
