Primary Outcome Measures:
  • Number of Participants With Objective Response [ Time Frame: Baseline, Week 9, and every 8 weeks up to Month 34 ] [ Designated as safety issue: No ]
    Number of participants with objective response based assessment of confirmed complete response (CR) or confirmed partial response (PR) according to Response Evaluation Criteria in Solid Tumors (RECIST). CR defined as disappearance of all target lesions. PR defined as a greater than or equal to 30 percent (≥30%) decrease in sum of the longest dimensions of the target lesions taking as a reference the baseline sum longest dimensions.


Secondary Outcome Measures:
  • Number of Participants With Clinical Benefit [ Time Frame: Baseline, Week 9, and every 8 weeks up to Month 34 ] [ Designated as safety issue: No ]
    The sum of participants with confirmed CR, PR, and stable disease (SD) greater than (>) 6 months according to RECIST. SD defined as neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for progressive disease, taking as reference smallest sum of longest dimensions since treatment started.

  • Number of Participants With Objective Response of Superficial Lesions [ Time Frame: Baseline, every 4 weeks up to Month 34 ] [ Designated as safety issue: No ]
    Number of participants with objective response based assessment of confirmed CR or PR of superficial lesions according to RECIST. Superficial lesions included skin lesions, chest wall lesions, and breast lesions and lymph nodes if followed up by physical examination.

  • Progression-Free Survival (PFS) [ Time Frame: Baseline up to Month 34 ] [ Designated as safety issue: No ]
    Time from date of randomization to date of first documentation of objective tumor progression or death due to any cause, whichever occurred first. PFS calculated as (Months)=(first event date minus randomization date plus 1) divided by 30.4.

  • Duration of Response (DR) [ Time Frame: Baseline up to Month 34 or early termination ] [ Designated as safety issue: No ]
    Time from first objective documentation of complete or partial response that was subsequently confirmed to first documentation of disease progression or death due to any cause, whichever occurred first. DR calculated as (Weeks)=(end date for DR minus first subsequent confirmed CR or PR plus 1) divided by 7.

  • Overall Survival (OS) [ Time Frame: Baseline until death (up to Month 34) ] [ Designated as safety issue: No ]
    Time from randomization to date of death due to any cause. OS (Months)=(death date minus date of first dose of study medication plus 1) divided by 30.4. For participants who were alive, overall survival was censored at last contact.

  • Number of Participants With Objective Response for Subgroup of Participants Whom Sunitinib Was at Least a Third Line Therapy [ Time Frame: Baseline, Week 9, and every 8 weeks up to Month 34 ] [ Designated as safety issue: No ]
    Number of participants with objective response based assessment of confirmed CR or PR according to RECIST. CR defined as disappearance of all target lesions. PR defined as ≥30% decrease in sum of the longest dimensions of the target lesions taking as a reference the baseline sum longest dimensions.
