A Study In Patients With Non-Small Cell Lung Cancer To Test If Erlotinib Plus SU011248 Is Better Than Erlotinib Alone

Overall survival is the duration from assignment to study medication to death. For participants who are alive, overall survival is censored at the last contact.

Time frame: Baseline to death or 28 days after last dose for the last participant

Population: The Full Analysis (FA) set included all participants who were randomized, with study drug assignment designated according to actual randomization, regardless of whether participants received study drug according to the randomization schedule, or received a different drug from that to which they were randomized.

Time in weeks from the first documentation of objective tumor response to objective tumor progression or death due to any cause. Duration of tumor response was calculated as (the date of the first documentation of objective tumor progression or death due to cancer minus the date of the first CR or PR that was subsequently confirmed plus 1) divided by 7.

Time frame: Baseline to disease progression or death or discontinuation from study or 28 days after last dose

Population: DR was calculated for the subgroup of participants from the FA set, with a confirmed objective tumor response.

EQ-5D: participant rated questionnaire to assess health-related quality of life in terms of a single utility score. Health State Profile component assesses level of current health for 5 domains: mobility, self-care, usual activities, pain and discomfort, and anxiety and depression; 1 indicates better health state (no problems); 3 indicates worst health state (eg, confined to bed). Scoring formula developed by EuroQol Group assigns a utility value for each domain in the profile. Score is transformed and results in total score range -0.594 to 1.000; higher score indicates better health state.

Time frame: Baseline and End of Treatment (EOT) or Withdrawal

Population: Patients Reported Outcome (PRO) Analysis Set included participants from the FA population who had at least one EQ-5D assessment while on treatment. The 'n' signifies those participants who received study drug and were evaluated for this measure at the timepoint for each group respectively.

The 1 year survival probability was defined as the probability of survival at one year after the date of the start of the study treatment based on the Kaplan Meier estimate.

Time frame: Baseline until death or until 28 days after last dose for the last participant

Population: The FA set included all participants who were randomized, with study drug assignment designated according to actual randomization, regardless of whether participants received study drug according to the randomization schedule, or received a different drug from that to which they were randomized.

Percentage of participants with OR based assessment of confirmed complete response (CR) or confirmed partial response (PR) according to Response Evaluation Criteria in Solid Tumors (RECIST) 1.0. Confirmed response are those that persist on repeat imaging study at least 4 weeks after initial documentation of response. CR are defined as disappearance of all lesions (target and/or non target). PR are those with at least 30% decrease in sum of the longest dimensions of target lesions taking as a reference the baseline sum longest dimensions, with non target lesions not increased or absent.

Time frame: Baseline to disease progression or discontinuation from study or 28 days after last dose

Population: The FA set included all participants who were randomized, with study drug assignment designated according to actual randomization, regardless of whether participants received study drug according to the randomization schedule, or received a different drug from that to which they were randomized.

Time in weeks from assignment to study medication to first documentation of objective tumor progression or death due to any cause. PFS was calculated as (first event date minus the date of first dose of study medication plus 1) divided by 7. Tumor progression was determined from oncologic assessment data (where data meet the criteria for progressive disease \[PD\]), or from adverse event (AE) data (where the outcome was Death).

Time frame: Baseline to disease progression or death due to any cause or 28 days after last dose

Population: The FA set included all participants who were randomized, with study drug assignment designated according to actual randomization, regardless of whether participants received study drug according to the randomization schedule, or received a different drug from that to which they were randomized.
