  • Sensitivity - Proportion of Participant Determinded to Have Clear Cell Renal Carcinoma (ccRCC) by PET/CT. [ Time Frame: 6 months ]
    Proportion of participants with ccRCC that were correctly identified on the PET/CT images.
  • Reading of Diagnostic CT Imaging in Renal Masses to Decide on the Presence or Absence of ccRCC. [ Time Frame: 6 months ]
  • Binary qualitative reading of 124I-cG250 based PET/CT imaging in renal masses and adjacent normal organ tissues to decide on the presence or absence of ccRCC. [ Time Frame: 6 months ]

Pre-surgical Detection of Clear Cell Renal Cell Carcinoma (ccRCC) Using Radiolabeled G250-Antibody
A Comparative Study of PET/CT Versus Diagnostic CT for the Detection of Clear Cell Renal Cell Carcinoma in Pre-surgical Patients With Renal Masses Using Iodine-124 Labeled Chimeric G250 (124I-cG250)
This is a multicenter Phase III study to demonstrate the diagnostic utility of 124I-cG250 PET/CT pre-surgical imaging in patients with operable renal masses.
A preoperative 124I-cG250 PET scan may distinguish between clear cell and non-clear cell renal carcinoma in patients with renal masses. Studies of imaging characteristics of 124I by a variety of PET cameras, quantification of tumor uptake of 124I-labeled antibody and correlation with biopsy measurement of tumor and normal tissue have met with encouraging results. As clear cell renal cancers are associated with an aggressive phenotype their a priori determination may help guide appropriate surgical/therapeutic management.
Phase 3
Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Diagnostic
  • Renal Cell Carcinoma
  • Kidney Cancer
  • Drug: 124-Iodine-cG250 (124I-cG250)
    i.v. and PET/CT scan 4+/-2 days after administration
    Other Name: Ca9-SCAN
  • Procedure: CT
    contrast enhanced CT scan
124-Iodine-cG250 (124I-cG250)
Single arm study, comparing 124I cG250 PET/CT and CT. Each patient underwent a PET/CT and CT scan days (+/-2days) after receipt of 124I cG250.
