Primary Outcome Measures:
  • Progression-free Survival (PFS) [ Time Frame: From randomization until the earliest date of disease progression or death (up to Study Week 191) ] [ Designated as safety issue: No ]
    PFS is defined as the interval between the date of randomization and the earliest date of progressive disease (PD), as defined by the Independent Review Committee (IRC), or death due to any cause. The IRC defined PD per Response Evaluation Criteria in Solid Tumors (RECIST), Version 1. Per RECIST, PD is defined as a >=20% increase in the sum of the longest diameter of target lesions, taking as reference the smallest sum longest diameter recorded since the treatment started or the appearance of >=1 new lesion. The Kaplan-Meier method was used for PFS estimates.


Secondary Outcome Measures:
  • Overall Survival [ Time Frame: From randomization until death (up to Study Week 268) ] [ Designated as safety issue: No ]
    Overall survival is defined as the time from randomization until death due to any cause.

  • Number of Participants in the Indicated Categories for Overall Response as Assessed by Independent Review [ Time Frame: From randomization until the time of a confirmed best response of CR or PR (up to Study Week 167) ] [ Designated as safety issue: No ]
    The number of participants with evidence of CR (the disappearance of all target and non-target lesions), PR (at least a 30% decrease in the sum of the longest diameters [LD] of target lesions, taking as a reference the Baseline sum LD), Stable Disease (small changes that do not meet previously given criteria), or Progressive Disease (a >=20% increase in target lesions within the first 12 weeks of treatment) was evaluated by an independent review per RECIST, Version 1.

  • Time to Response [ Time Frame: From randomization until the time of the first documented confirmed complete or partial response (up to Study Week 167) ] [ Designated as safety issue: No ]
    Time to response is defined as the time from the start of treatment until the first documented evidence of CR (the disappearance of all target and non-target lesions) or PR (at least a 30% decrease in the sum of the LD of target lesions, taking as a reference the Baseline sum LD), whichever comes first. CR and PR were evaluated by an independent review per RECIST, Version 1.

  • Duration of Response (DOR) [ Time Frame: From the time of the first documented confirmed complete or partial response until disease progression or death, if sooner (up to Study Week 167) ] [ Designated as safety issue: No ]
    DOR is defined as the time from the first documented evidence of response (CR or PR) until the first documented sign of disease progression (a >=20% increase in the sum of the longest diameter of target lesions, taking as reference the smallest sum longest diameter recorded since the treatment started or the appearance of >=1 new lesion) or death, if sooner. CR=the disappearance of all target and non-target lesions. PR=at least a 30% decrease in the sum of the LD of target lesions, taking as a reference the Baseline sum LD.

  • Number of Participants (Par.) With Serious Adverse Events (SAEs)/Non-serious Adverse Events (Any Untoward Medical Occurrence in a Par. Administered a Pharmaceutical Product and Which Does Not Necessarily Have a Causal Relationship With This Treatment) [ Time Frame: From the time of the first dose of study drug to approximately one month after the discontinuation of study drug (up to Study Week 268) ] [ Designated as safety issue: No ]
    See the SAE/AE module for a list of all SAEs/AEs. SAE=any event occurring at any dose that results in any of the following: death, a life-threatening adverse drug experience (ADE; at immediate risk of death from the experience as it occurred), inpatient hospitalization/prolongation of existing hospitalization, a persistent/significant disability/incapacity, a congenital anomaly/birth defect, or a Grade 4 laboratory abnormality. Events that may not result in death, be life-threatening, or require hospitalization may be considered to be a serious ADEs when based upon appropriate medical judgment.

  • Change From Baseline in Functional Assessment of Chronic Illness Therapy-Fatigue (FACIT-F) Scale Scores at Day 28 of Cycles 1-4 (Average of Weeks 4, 10, 16, and 22, Respectively) [ Time Frame: Baseline (predose); Weeks 4, 10, 16, and 22 ] [ Designated as safety issue: No ]
    The FACIT-F scale measures the severity and impact of fatigue on functioning and health related quality of life (HRQoL) experienced in the past seven days. The level of fatigue is measured by 13 questions assessed on a four-point scale (0=not at all fatigued; 1=a little bit fatigued; 2=somewhat fatigued; 3=quite a bit fatigued; 4=very much fatigued; possible total score of 0 to 52). A negative change from Baseline represents a worsening condition. Change from Baseline was calculated as the assessment week value minus the Baseline value.

  • Change From Baseline in the FACT-Kidney Symptom Index-19 (FKSI-19) Scale Disease-related Symptoms-physical (DRS-P) Domain Score at Day 28 of Cycles 1-4 (Average of Weeks 4, 10, 16, and 22, Respectively) [ Time Frame: Baseline; Weeks 4, 10, 16, and 22 ] [ Designated as safety issue: No ]
    The FKSI-19 is a disease-specific instrument that measures disease and treatment-related symptoms specifically in renal cancer patients in 4 domains. The DRS-P domain assesses symptoms experienced in the past 7 days. Participants are asked to respond to 12 questions ("I have a lack of energy," "I feel pain," for example) by using a 5-point scale (0=not at all, 1=a little bit, 2=somewhat, 3=quite a bit, 4=very much; possible total domain score of 0 to 48). Higher scores represent better health. A negative change from Baseline represents a worsening of condition.

  • Change From Baseline in the FACT-Kidney Symptom Index-19 (FKSI-19) Scale Disease Related Symptoms-emotional (DRS-E) Domain Score at Day 28 of Cycles 1-4 (Average of Weeks 4, 10, 16, and 22, Respectively) [ Time Frame: Baseline; Weeks 4, 10, 16, and 22 ] [ Designated as safety issue: No ]
    The FKSI-19 is a disease-specific instrument measuring disease and treatment-related symptoms specifically in renal cancer patients in 4 domains. The DRS-E domain assesses symptoms experienced in the past 7 days. Participants are asked to respond to the question of "I worry that my condition will get worse" by using a 5-point scale (0=not at all, 1=a little bit, 2=somewhat, 3=quite a bit, 4=very much; possible total domain score of 0 to 4). A negative change from Baseline (BL) represents a worsening of condition. Change from BL was calculated as the assessment week value minus the BL value.

  • Change From Baseline in the FACT-Kidney Symptom Index-19 (FKSI-19) Scale Treatment Side Effects (TSE) Domain Score at Day 28 of Cycles 1-4 (Average of Weeks 4, 10, 16, and 22, Respectively) [ Time Frame: Baseline; Weeks 4, 10, 16, and 22 ] [ Designated as safety issue: No ]
    The FKSI-19 is a disease-specific instrument that measures disease and treatment-related symptoms specifically in renal cancer patients in 4 domains. The TSE domain assesses side effects experienced in the past 7 days. Participants are asked to respond to 3 questions ("I have nausea," "I have diarrhea," and "I am bothered by side effects of treatment") by using a 5-point scale (0=not at all, 1=a little bit, 2=somewhat, 3=quite a bit, 4=very much; possible total domain score of 0 to 12).Higher scores represent better health. A negative change from Baseline represents a worsening of condition.

  • Change From Baseline in the FACT-Kidney Symptom Index-19 (FKSI-19) Scale Functional Well Being (FWB) Domain Score at Day 28 of Cycles 1-4 (Average of Weeks 4, 10, 16, and 22, Respectively) [ Time Frame: Baseline; Weeks 4, 10, 16, and 22 ] [ Designated as safety issue: No ]
    The FKSI-19 is a disease-specific instrument that measures disease and treatment-related symptoms specifically in renal cancer patients in 4 domains. The FWB domain assesses well being in the past 7 days. Participants are asked to respond to 3 questions ("I am able to work," "I am able to enjoy life," and "I am content with the quality of my life now") by using a 5-point scale (0=not at all, 1=a little bit, 2=somewhat, 3=quite a bit, 4=very much; possible total domain score of 0 to 12). Higher scores represent better health. A negative change from Baseline represents a worsening of condition.

  • Change From Baseline in the FACT-Kidney Symptom Index-19 (FKSI-19) Scale Total Score at Day 28 of Cycles 1-4 (Average of Weeks 4, 10, 16, and 22, Respectively) [ Time Frame: Baseline; Weeks 4, 10, 16, and 22 ] [ Designated as safety issue: No ]
    The FKSI-19 is a disease-specific instrument that measures disease and treatment-related symptoms specifically in renal cancer patients in 4 domains (DRS-P, DRS-E, TSE, and FWB). Participants are asked to respond to a total of 19 questions regarding symptoms, side effects, and well being by using a 5-point scale (0=not at all, 1=a little bit, 2=somewhat, 3=quite a bit, 4=very much; possible total score of 0 to 76). Higher scores represent better health. A negative change from Baseline represents a worsening of condition.

  • Change From Baseline in the Supplementary Quality of Life Questions (SQLQ) Scale Worst Soreness Scores at Day 28 of Cycles 1-4 (Average of Weeks 4, 10, 16, and 22, Respectively) [ Time Frame: Baseline; Weeks 4, 10, 16, and 22 ] [ Designated as safety issue: No ]
    The SQLQ scale consists of 5 items that assess the worst mouth and throat, hand, and foot soreness, as well as limitations due to mouth/throat and foot soreness. Participants were asked to assess their worst mouth/throat, hand, and foot soreness by answering the question of " In the past 4 weeks, what was your worst mouth/throat, hand, and foot soreness?" by using the following 4-point scale: 0, I never had any soreness; 1, I had a little bit of soreness; 2, I had quite a lot of soreness; 3, I had severe soreness. A positive mean change from Baseline represents a worsening of condition.

  • Change From Baseline in the Supplementary Quality of Life Questions (SQLQ) Limitations Due to Mouth and Throat Soreness Score at Day 28 of Cycles 1-4 (Average of Weeks 4, 10, 16, and 22, Respectively) [ Time Frame: Baseline; Weeks 4, 10, 16, and 22 ] [ Designated as safety issue: No ]
    The SQLQ consists of 5 items assessing the worst mouth/throat, hand, and foot soreness, and limitations due to mouth/throat and foot soreness. Participants (par.) assessed the limitations caused by their mouth/throat soreness by answering the question of "In the past 4 weeks, how much did your worst mouth/throat soreness limit you in the following activities: swallowing/eating/drinking/talking/sleeping" by using the following 4-point scale: 0, not limited; 1, limited a little; 2, limited a lot; 3, unable to do. The overall limitation score (15=best; 0=worst), based on the individual scores for the 5 activities, is derived as follows: the actual scores were rescored by subtracting the actual score from "3" for each of the 5 categories. A high score indicates less limitation. Change from Baseline was calculated as the assessment week value minus the Baseline value. A negative mean change from Baseline represents a worsening of condition.

  • Change From Baseline in the Supplementary Quality of Life Questions (SQLQ) Limitations Due to Foot Soreness Scores at Day 28 of Cycles 1-4 (Average of Weeks 4, 10, 16, and 22, Respectively) [ Time Frame: Baseline; Weeks 4, 10, 16, and 22 ] [ Designated as safety issue: No ]
    The SQLQ consists of 5 items assessing the worst mouth/throat, hand, and foot soreness, and limitations due to mouth/throat and foot soreness. Par. assessed the limitations caused by their foot soreness by answering the question of "In the past 4 weeks, how much did your worst foot soreness limit you in each of the following activities: standing/walking/climbing stairs/sleeping/ability to do usual activities" by using the following 4-point scale: 0, not limited; 1, limited a little; 2, limited a lot; 3, unable to do. The overall limitation score (15=best; 0=worst), based on the individual scores for the 5 activities, is derived as follows: the actual scores were rescored by subtracting the actual score from "3" for each of the 5 categories. A high score indicates less limitation. Change from Baseline was calculated as the assessment week value minus the Baseline value. A negative mean change from Baseline represents a worsening of condition.

  • Summary of Analysis for the Cancer Treatment Satisfaction Questionnaire (CTSQ) Score at Day 28 of Cycles 1-4 (Average of Weeks 4, 10, 16, and 22, Respectively) [ Time Frame: Weeks 4, 10, 16, and 22 ] [ Designated as safety issue: No ]
    The CTSQ assesses 3 domains related to the participant's satisfaction with cancer therapy: Expectations of Therapy (ET), Feelings about Side Effects (FSE), and Satisfaction with Therapy (SWT). Participants shared their thoughts on their cancer therapy (9 questions), their satisfaction with their most recently administered cancer therapy (6 questions), and if they would take the same cancer therapy if given the choice to do so again. All questions were assessed on a 5-point scale; 1, never; 5, always. Scores were averaged and transformed to a 0-100 scale; higher scores represent better health.

  • Medical Resource Utilization (MRU): Assessed as the Mean Number of Non-study Medical Visits, Telephone Consultations, Hospital Days, and Emergency Room (ER) Visits Per 30 Days Through Week 24 [ Time Frame: From Day 1 up to Week 24 ] [ Designated as safety issue: No ]
    Non-study medical visits were defined as the sum of primary care physician visits, nurse practitioner/physician's assistant/nurse visits, and medical or surgical specialist visits. Days hospitalized were defined as the sum of days in the general ward and days in intensive care. The number of telephone consultations and ER visits was assessed via individual questions on the electronic Case Report Form. The endpoint was totaled through Week 24, divided by the number of days on treatment for each participant, then multiplied by 30 days to get the number of visits per 30 days.

  • MRU: The Mean Number of Laboratory Visits, Radiology Visits, Home Healthcare Visits, and Medical Procedures for Cycles 1-4. MRU Data Collected at Day 28 of Cycles 1-4 (Average of Weeks 4, 10, 16, and 22, Respectively) [ Time Frame: Weeks 4, 10, 16, and 22 ] [ Designated as safety issue: No ]
    The number of non-study laboratory visits (NSLVs), non-study radiology visits (NSRVs), and home healthcare visits (HHVs) were each collected as a single question on the eCRF. The number of non-study medical or surgical procedures (MSPs) was defined as the sum of procedures performed at outpatient or physician clinics, as well as those performed during any inpatient hospitalization.
