Brief Summary:
The main purpose of this study is to compare the objective response rate (ORR) and overall survival (OS) of bempegaldesleukin (NKTR-214: BEMPEG) combined with nivolumab to that of tyrosine kinase inhibitor (TKI) monotherapy (sunitinib or cabozantinib) in IMDC intermediate- or poor-risk patients and IMDC all-risk patients with previously untreated advanced renal cell carcinoma (RCC).

Outcome Measures
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. Objective Response Rate (ORR) Per mRECIST 1.1 by BICR in IMDC All-risk Patients and Intermediate- or Poor (I/P)-Risk Patients With Previously Untreated Advanced RCC [ Time Frame: Approximately 32 months ]

    ORR using modified Response Evaluation Criteria in Solid Tumors (mRECIST) 1.1 by Blinded Independent Central Review (BICR) in International Metastatic Renal Cell Carcinoma Database Consortium (IMDC) All-risk patients and intermediate- or poor-risk patients.

    ORR is defined as the proportion of enrolled participants who achieved a Best Overall Response (BOR) of Complete Response (CR) or Partial Response (PR). CR is defined as disappearance of all target lesions. Any pathological lymph nodes (whether target or non-target) had to have reduction in short axis to <10 mm. PR is defined as at least a 30% decrease in the sum of diameters of target lesions, taking as reference the baseline sum diameters. ORR is calculated as the sum of CR and PR.


  2. Overall Survival (OS) in IMDC All-Risk and Intermediate- or Poor-risk Patients With Previously Untreated Advanced RCC [ Time Frame: Approximately 32 months ]
    OS is defined as the time from date of first dose to the date of death from any cause. Patients without a date of death were censored at their last known alive date.


Secondary Outcome Measures :
  1. Progression Free Survival (PFS) Per mRECIST 1.1 by BICR in IMDC All-risk Patients and Intermediate- or Poor (I/P)-Risk Patients With Previously Untreated Advanced RCC [ Time Frame: Approximately 32 months ]
    Progression-free survival is defined as the time between the date of randomization and the first date of documented tumor progression using mRECIST 1.1 per BICR or death due to any cause, whichever comes first.
