ClinicalTrials.gov Identifier: NCT01582672

Brief Summary:
This is a trial of AGS-003, which is being studied as a possible treatment for Advanced Renal Cell Carcinoma. The purpose of this study is to determine whether there is an overall survival (OS) benefit between subjects treated with AGS-003 in combination with standard treatment versus subjects treated with standard treatment alone.

Condition or disease Intervention/treatment Phase
Advanced Renal Cell Carcinoma Renal Cell Carcinoma Metastatic Renal Cell Carcinoma Drug: Standard Treatment Biological: AGS-003 Phase 3

Detailed Description:
This study will investigate the combination of an autologous ribonucleic acid (RNA) electroporated dendritic cell (DC) based immunotherapy, AGS-003, plus standard treatment (initiating with sunitinib). The primary objective in this study is to determine the median OS achieved by this combination compared to the OS resulting from use of active control (standard treatment), in a population of adults with advanced renal cell carcinoma (RCC), with nephrectomy indicated, and with remaining metastatic disease.

Primary Outcome Measures :
  1. Overall Survival [ Time Frame: From date of subject randomization to date of death; assessed up to 42 months or until 290 deaths have been accrued on study ]
    Duration from randomization to death

Secondary Outcome Measures :
  1. Progression Free Survival [ Time Frame: From date of subject randomization to date of progression; assessed up to 42 months ]
  2. Tumor Response [ Time Frame: From date of subject randomization to date of progression; assessed up to 42 months ]
    Monitor for evidence of the following tumor responses: Objective response rate, Duration of overall response, and Disease control rate.

  3. Monitor treatment emergent adverse events between both arms [ Time Frame: From safety baseline until either meeting a discontinuation criterion or death; assessed up to 42 months ]
    Compare adverse events between both arms.
