The purpose of this study is to determine whether Interleukin-2 at the dose and schedule used in this study will help increase tumor shrinkage.
Condition or disease
Renal Cell Cancer MetastaticKidney Cancer Metastatic
In this phase II study, the IL-2 schedule (daily IL-2 for 5 days (per week) every 3 weeks) will be tested in a cohort of kidney cancer patients to attempt to determine the response rate, median duration of response, and median survival. The dose intensity of this schedule would allow a patient treated on this regimen to achieve the target threshold (> 1440 million IU/m2/year).
Number of Participants With Response Using RECIST Criteria [ Time Frame: Measured until Disease Progression or death from any cause up to 2 year ]
Radiographic studies to evaluate for response were done after every 2 cycles (6 weeks) until disease progression or death from any cause up to 2 years. Standard RECIST response criteria were utilized. Response Evaluation Criteria In Solid Tumors Criteria (RECIST v1.0) for target lesions and assessed by CT scan: Complete Response (CR), Disappearance of all target lesions; Partial Response (PR), >=30% decrease in the sum of the longest diameter of target lesions; Overall Response Rate (ORR) = 100%(CR + PR/total number of patients receiving Interleukin-2).
Secondary Outcome Measures
Median Duration of Response [ Time Frame: Measured from first response until Disease Progression or death from any cause up to 2 years ]
Duration of response is calculated as the time (months) from the date at which response is first observed (per standard Response Evaluation Criteria In Solid Tumors [RECIST] to the date of first observed disease progression or date of death from any cause, whichever came first, assessed up to 2 years. The actual date of tumor assessments was used for this calculation. Progression is defined using Response Evaluation Criteria In Solid Tumors Criteria (RECIST v1.0), as a 20% increase in the sum of the longest diameter of target lesions, or a measurable increase in a non-target lesion, or the appearance of one or more new lesions.
Median Survival [ Time Frame: measured from date of first dose until date of death ]
