Phase I: To determine the dose of temsirolimus to be used in phase II part of the study

Phase II:

To determine overall survival Secondary objectives

• To evalulate response rate
• To evaluate time to progression (TTP)
• To evalulate time to partial response (time to PR or better)(TPR)
• To evaluate quality of life
• To evaluate tolerability and safety
