Study Details

Study Description

Brief Summary

The purpose of this study is to determine the biochemical response rate (PSA) to single agent RAD001 in patients with metastatic hormone-refractory prostate cancer (HRPC).

Condition or Disease Intervention/Treatment Phase
Phase 2

Detailed Description

This is a single center, Phase II study of RAD001 in men with HRPC. The study design is a straight forward, two-stage design with tumor biopsies scheduled at screening and again at 4 weeks. FLT-PET scans are performed at screening and again at day 28, following initiation of treatment in the first 10 patients. Patients are assessed for adverse events every two weeks for the first month and monthly thereafter. Patients are assessed for response by PSA every 4 weeks and when applicable, for objective response every 2 months. If 4 or more responses are seen in the first 39 patients then the study will expand to 60 patients.

  • Outcome Measures

    Primary Outcome Measures

    1. Biochemical Response Rate [Patients were followed for a median of 315 days]

      Number of participants with 50% decline in serum PSA from baseline was pre-set as the primary measure of disease response.

    Secondary Outcome Measures

    1. Pathologic Response [Patients were followed for a median of 315 days]

      Number of participants with either a 50% or greater decrease in proliferation index or a 50% or greater increase in apoptotic index

    2. Progression Free Survival [Patients were followed for a median of 315 days, with the last patient censored at 1309 days.]

      Time in months from the start of study treatment to the date of first progression according to RECIST 1.0, or to death due to any cause. Patients alive who had not progressed as of the last follow-up had PFS censored at the last follow-up date. Median PFS was estimated using a Kaplan-Meier curve.

    3. Molecular Response [Patients were followed for a median of 315 days]

      Functional extent of mTOR inhibition by changes in the phosphorylation status of pS6 in prostate tumors.

    4. Clinical Response [Patients were followed for a median of 315 days]

      The percentage of participants with a complete or partial response as defined by RECIST 1.0. Response Criteria are defined below: Complete Response: Disappearance of all target lesions Partial Response: At least a 30% decrease in the sum of the longest diameter (LD) of target lesions, taking as reference the baseline sum LD Progressive Disease: At least a 20% increase in the sum of the 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 Stable Disease: Neither sufficient shrinkage to qualify for partial response nor sufficient increase to qualify for progressive disease, taking as reference the smallest sum LD
