Brief Summary:

RATIONALE: Monoclonal antibodies can locate tumor cells and either kill them or deliver tumor-killing substances to them without harming normal cells. It is not yet known whether monoclonal antibody therapy is effective in treating kidney cancer.

PURPOSE: This randomized phase III trial is studying monoclonal antibody therapy to see how well it works in treating patients who have undergone surgery for nonmetastatic primary kidney cancer.

Condition or disease Intervention/treatment Phase
Kidney Cancer Biological: girentuximab Other: placebo Phase 3

Detailed Description:



  • Evaluate the disease-free and overall survival of patients with primary clear cell renal cell carcinoma at high risk for recurrence treated with chimeric monoclonal antibody cG250 (WX-G250) vs placebo in an adjuvant setting.


  • Evaluate the safety of these drugs in these patients.
  • Assess the quality of life of patients treated with this drug.
  • Perform pharmacokinetic analysis of WX-G250.

OUTLINE: This is a randomized, double-blind, placebo-controlled, multicenter study. Patients are stratified according to risk criteria and participating centers (US vs Non-US). Patients are randomized to 1 of 2 treatment arms.

  • Arm I: Patients receive monoclonal chimeric antibody cG250 (WX-G250) IV over 15 minutes once weekly for 24 weeks.
  • Arm II: Patients receive placebo IV over 15 minutes once weekly for 24 weeks. In both arms, treatment continues in the absence of disease progression or unacceptable toxicity.

Blood samples are collected for pharmacokinetic analysis.

Quality of life is assessed at baseline, at weeks 12 and 24 during treatment, and then at 6 months after completion of study treatment.

Patients are followed every 3 months during years 1 and 2, every 6 months during years 3 and 4, and then annually during year 5 and thereafter.

PROJECTED ACCRUAL: A total of 864 patients out of the expected 856 (428 per treatment arm) were accrued for this trial.

Official Title: A Randomized, Double Blind Phase III Study To Evaluate Adjuvant cG250 Treatment Versus Placebo In Patients With Clear Cell RCC And High Risk of Recurrence (ARISER)
Study Start Date : July 2004
Actual Primary Completion Date : October 2012
Actual Study Completion Date : October 2012

Arm Intervention/treatment
Experimental: Arm I
Patients receive monoclonal chimeric antibody cG250 (synonym names: Rencarex®, girentuximab, and WX-G250) IV over 15 minutes once weekly for 24 weeks.
Biological: girentuximab
Given IV
Other Name: Rencarex®, cG250 and WX-G250

Placebo Comparator: Arm II
Patients receive placebo IV over 15 minutes once weekly for 24 weeks.
Other: placebo
Given IV

Primary Outcome Measures :
  1. Disease-free Survival [ Time Frame: Until signs of recurrence or until 360 local DFS events have occurred (median follow-up of 4.5 years) ]
    Disease Free Survival (DFS) calculated from the date of randomization up to and including the date of documented relapse as confirmed by the CT, death or start of new anti-tumor therapy.

  2. Overall Survival [ Time Frame: After 419 OS events or 60 months after the last patient has been enrolled, whichever is the later (median follow-up of 4.5 years) ]
    Overall Survival (OS) calculated from the date of randomization to the date of death. Patients with no documented death will be censored at the date of their last study evaluation.

Secondary Outcome Measures :
  1. Quality of Life - Global Health Status [ Time Frame: At 12 months ]
    Quality of life by EORTC Quality of Life Questionnaire-C30 - Global Health Status at 12 months. A high score for the global health status/QoL represents a high QoL with 0 being the minimum and 100 being the maximum.

  2. Pharmacokinetics of WX-G250 [ Time Frame: Week 8 ]
    Quantitative determination of cG250 (Girentuximab) trough serum profiles at week 8 (steady state concentration).
