Primary Outcome Measures :
  1. Progression-Free Survival (PFS), Core Radiology Assessment [ Time Frame: Day 28 of each 6-week cycle: duration of treatment phase ]
    Progression-free survival (PFS) = time from randomization to first documentation of objective tumor progression or to death due to any cause, whichever occured first. If tumor progression data included more than 1 date, the first date was used. PFS = first event date minus the date of randomization + 1. On study included treatment plus 28-day follow-up periods.

  2. Progression-Free Survival (PFS), Investigator's Assessment [ Time Frame: Day 28 of each 6-week cycle: duration of treatment phase ]
    Progression-free survival = time from randomization to first documentation of objective tumor progression or to death due to any cause, whichever occured first. PFS = first event date minus the date of randomization + 1). On study included treatment plus 28-day follow-up periods.


Secondary Outcome Measures :
  1. Objective Response, Core Radiology Assessment [ Time Frame: Day 28 of each 6-week cycle: duration of treatment phase ]
    Objective response (OR) = the number of patients with confirmed complete response (CR) and confirmed partial response (PR) according to the Response Evaluation Criteria in Solid Tumors (RECIST) criteria, relative to all randomized patients. CR was defined as the disappearance of all target lesions. PR was defined as a ≥ 30% decrease in the sum of the longest dimensions of the target lesions taking as a reference the baseline sum longest dimensions. Confirmed responses (CR or PR) = those that persisted on repeat imaging study >= 4 weeks after initial documentation of response.

  2. Objective Response, Investigator's Assessment [ Time Frame: Day 28 of each 6-week cycle: duration of treatment phase ]
    Objective response (OR) = the number of patients with confirmed complete response (CR) and confirmed partial response (PR) according to the Response Evaluation Criteria in Solid Tumors (RECIST) criteria, relative to all randomized patients. CR was defined as the disappearance of all target lesions. PR was defined as a ≥ 30% decrease in the sum of the longest dimensions of the target lesions taking as a reference the baseline sum longest dimensions. Confirmed responses = those that persist on repeat imaging study >= 4 weeks after initial documentation of response.

  3. Overall Survival (OS) [ Time Frame: Clinic visit or telephone contact every 2 months until death ]
    Overall survival (OS) = time from date of randomization to date of death due to any cause. For patients not expiring, survival time was censored at the last date they were known to be alive. Patients lacking data beyond randomization had their survival times censored at the date of randomization with a duration of 1 day.

  4. Time to Tumor Progression (TTP), Core Radiology Assessment [ Time Frame: Randomization to first documentation of tumor progression: duration of treatment phase ]
    TTP = time from randomization to first documentation of objective tumor progression. TTP data were censored on the day following the date of last on treatment (including 28 day follow-up period) tumor assessment documenting absence of progressive disease for subjects who did not have objective tumor progression while on treatment or who were given anti-tumor treatment other than study treatment prior to documentation of objective tumor progression. Subjects with no tumor assessments after randomization had TTP censored on the date of randomization with a duration of 1 day.

  5. Time to Tumor Progression (TTP), Investigator's Assessment [ Time Frame: Randomization to first documentation of tumor progression: duration of treatment phase ]
    TTP = time from randomization to first documentation of objective tumor progression. TTP data were censored on the day following the date of last on treatment (including 28 day follow-up period) tumor assessment documenting absence of progressive disease for subjects who did not have objective tumor progression while on treatment or who were given anti-tumor treatment other than the study treatment prior to documentation of objective tumor progression. Subjects with no tumor assessments after randomization had TTP censored on the date of randomization with a duration of 1 day.

  6. Duration of Response (DR), Core Radiology Assessement [ Time Frame: Day 28 of each cycle: duraton of treatment phase ]
    Duration of response (DR) = time from the first documentation of objective tumor response to the first documentation of objective tumor progression or to death due to any cause. DR data were censored on the day following the date of the last on treatment (including 28 day follow-up period) tumor assessment documenting absence of progressive disease for subjects without objective tumor progression who did not die due to any cause while on treatment or who were given anti-tumor treatment other than study treatment prior to observing tumor progression.

  7. Duration of Response (DR), Investigator's Assessment [ Time Frame: Day 28 of each cycle: duration of treatment phase ]
    Duration of response (DR) = time from the first documentation of objective tumor response to the first documentaion of objective tumor progression or to death due to any cause. DR data were censored on the day following the date of the last on treatment (including 28 day follow-up period) tumor assessment documenting absence of progressive disease for subjects without objective tumor progression who did not die due to any cause while on treatment or who were given anti-tumor treatment other than study treatment prior to observing tumor progression.

Each question was answered on a five-point Likert-type scale ranging from 0 (not at all) to 4 (very much). Score = the sum score of the item scores in the subscale; total range: 0 to 36.

  15. EuroQoL Five Dimension (EQ-5D) Health State Index [ Time Frame: Day 1 & 28 of each cycle: duration of treatment phase ]
    EQ-5D Health State Index: a brief, self-administered generic health status instrument. Respondents were asked to describe their current health state on each of 5 dimensions (mobility, self-care, usual activities, pain/discomfort, and anxiety or depression) on a three-level scale (1=no problem, 2=some problem, and 3=extreme problem). A maximum score of 1 can be derived from these 5 dimensions by score conversion; range: -0.39 (worst health state)to 1.00 (best health state). This descriptive system classifies respondents into one of 243 possible distinct health states (EQ-5D descriptive system).

  16. Euro-QoL Visual Analog Scale (EQ-VAS) [ Time Frame: Day 1 & 28 of each cycle: duration of treatment phase ]
    EQ-VAS: overall self-rating rating of the patient's current health state using a 20 cm Visual Analog Scale (EQ-VAS), also called the health state thermometer) is a metric measurement (in 2 mm interval) from the visual analog scale which ranges between 0 (worse imaginable health state) and 100 (best imaginable health state).

    Plasma concentrations of soluble proteins that may be associated with tumor proliferation or angiogenesis collected from a subset of patients were analyzed by enzyme-linked immunosorbent assay (ELISA) analysis. Soluble protein values: Baseline concentration (pM) and ratio to Baseline at each timepoint; ratio = plasma concentration of soluble protein (picograms per milliliter [pg/ml]) at timepoint / concentration of soluble protein (pg/ml) at baseline.

Soluble protein values: Baseline concentration (pM) and ratio to Baseline at each timepoint; ratio = plasma concentration of soluble protein (picograms per milliliter [pg/ml]) at timepoint / concentration of soluble protein (pg/ml) at baseline. Samples below the limit of quantitation and samples with insufficient volume available were excluded.

  19. Incremental Cost Effectiveness Ratio (ICER) [ Time Frame: post study measurement ]
    Incremental cost effectiveness ratio (ICER) of sunitinib compared to IFN-a as first-line treatment for MRCC, defined as the ratio of the incremental cost of treatment over the incremental effectiveness; effectiveness measured as quality adjusted life year (QALY) gain. This objective was not addressed in the clinical study report, but an interim analysis of cost-effectiveness was presented separately. These results were not available for inclusion at the time of this posting.

Steady-state observed trough concentrations were dose corrected to the starting dose (reference dose) where appropriate. Concentrations below the limits of quantitation (BLQ) were set to 0. Ctrough = minimum (trough) plasma concentration (nanograms per milliliter [ng/mL]).
