|Official Title:||Phase II Study of Interleukin-2 in Combination With Zoledronic Acid in Patients With Untreated Metastatic Renal Cell Carcinoma|

|Actual Study Completion Date :||September 2008|
Interleukin-2 subcutaneous injection days 1-5, on weeks 1 through 3, in four week (28 days) cycles in combination with Zoledronic acid IV on day 1 of every 4 week (28 days) cycle.
Interleukin-2 will be given at a starting dose of 7 MU/m2/day by subcutaneous injection days 1-5, on weeks 1 through 3, in four week (28 days) cycles.
Other Name: Interleukin-2Drug: Zoledronic acid
Zoledronic acid will be given on day 1 intravenously over 15 or 30 minutes starting at 400mcg. If no significant increase in gamma delta-T cell augmentation is seen, the dose of zoledronic acid will be increased in the subsequent cycle up to a maximum dose of 3mg.

- Number of Subjects With Antitumor Response With Low-dose Interleukin-2 in Combination With Zoledronic Acid [ Time Frame: CT scans obtained at baseline, then every 2 cycles ]Anti-tumor response was measured per RECIST criteria (V1.0) and assessed by chest/abdomen/pelvis CT: Complete Response (CR), disappearance of all target lessions; Partial Response (PR), >=30% decrease in the sum of the longest diameter (LD) of target lesions; Stable Response (SD), Neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for progressive disease, taking as reference the smallest sum LD since the treatment started.
- Number of Participants With Overall Survival and Progression-free Survival at 24 Weeks [ Time Frame: Time frame is from study entry until time to disease progression and time to death, up to 50 months ]All 12 patients were followed for survival until death. 8 participants who received more than one cycle of treatment and who were considered evaluable for response were followed until time to progression. Disease progression was determined by CT scans of the chest/abdomen/pelvis obtained every 2 cycles and based on RECIST version 1.0. Progression is defined using RECIST (V1.0) at least a 20% increase in the sum of the longest diameter (LD)of target lesions, taking as reference the smallest sum LD recorded since the treatment started or the appearance of one or more new lesions
- Number of Participants With Toxicities [ Time Frame: Baseline to 30 days after last dose of study treatment ]Patients were observed for toxicities. The National Cancer Institute Common Terminology Criteria Version 2.0 was used to categorize and report adverse events.
- Number of Participants With Immunologic Responses [ Time Frame: baseline to cycle 2 day 8 ]Blood was collected to analyze T-cell populations from all patients prior to treatment on day 1 of cycles 1 and 2, and days 4 and 8 of cycles 1 and 2. Changes in gamma delta T-cell population and CD3 T-cell populations were reported.
