A Study of Avastin (Bevacizumab) in Combination With Gemcitabine With or Without Cisplatin in First-Line Treatment of Elderly Patients With Non-Small Cell Lung Cancer

Disease progression was assessed according to Response Evaluation Criteria In Solid Tumors (RECIST) criteria version 1.1 (v 1.1). Disease progression was defined at least a 20% increase in the sum of diameters of target lesions compared to smallest sum of diameters on-study and absolute increase of at least 5 millimeter (mm), progression of existing non-target lesions, or presence of new lesions.

Time frame: Month 6

Population: Intent-to-treat (ITT) set included all participants in the RND set who received at least one dose of any study medication; participants were classified according to treatment received.

DoR was defined for participants who had achieved an objective response (CR/PR) (whichever status was recorded first) as the time period from first documentation of a response to the date of first occurrence of investigator documented disease progression or death. CR was defined as disappearance of all target and non-target lesions and no new lesions, all pathological lymph nodes must have decreased to \<10 mm in short axis. PR was defined as at least a 30% decrease in the sum of diameters of target lesions (taking as reference the baseline sum diameters), no progression in non-target lesions, and no new lesions. Disease progression was defined as increase by at least 20% in the sum of the longest diameters of each target lesion, taking as a reference the smallest sum of the longest diameters or appearance of one or more new lesions. DoR was estimated using Kaplan Meier method.

Time frame: Baseline; Day 15 of Cycles 3 and 6; Month 6 and then every 3 months until disease progression, death or consent withdrawal (up to 53 months)

Population: ITT set.

OS was defined as the interval between the date of randomization and death from any cause. OS was estimated using Kaplan Meier method.

Time frame: From randomization to death or end of the study (up to 53 months)

Population: ITT set

Time frame: 1 year

Population: ITT set

Best overall response was defined as the best response recorded from the start of the treatment until disease progression/recurrence, assessed according to RECIST criteria v 1.1. Complete Response (CR): disappearance of all target and non-target lesions and no new lesions, all pathological lymph nodes must have decreased to less than (\<) 10 millimeter (mm) in short axis; Partial Response (PR): at least a 30% decrease in the sum of diameters of target lesions (taking as reference the baseline sum diameters), no progression in non-target lesion, and no new lesions; Progressive Disease (PD): at least 20% increase in the sum of diameters of target lesions compared to smallest sum of diameters on-study and absolute increase of at least 5 mm, progression of existing non-target lesions, or presence of new lesions; Stable Disease (SD): neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for PD, taking as reference the smallest sum diameters while on study.

Time frame: Baseline; Day 15 of Cycles 3 and 6; Month 6 and then every 3 months until disease progression, death or consent withdrawal (up to 53 months)

Population: ITT set

Time frame: From randomization to death or end of the study (up to 53 months)

Population: ITT set

Objective response was defined as having a CR or PR according to a RECIST criteria v 1.1. CR was defined as disappearance of all target and non-target lesions and no new lesions, all pathological lymph nodes must have decreased to \<10 mm in short axis. PR was defined as at least a 30% decrease in the sum of diameters of target lesions (taking as reference the baseline sum diameters), no progression in non-target lesions, and no new lesions.

Time frame: Cycle 3 Day 15, Cycle 6 Day 15 and at Month 6

Population: ITT set

Disease control was defined as having CR/PR/SD as per RECIST criteria v 1.1. CR was defined as disappearance of all target and non-target lesions and no new lesions, all pathological lymph nodes must have decreased to \<10 mm in short axis. PR was defined as at least a 30% decrease in the sum of diameters of target lesions (taking as reference the baseline sum diameters), no progression in non-target lesions, and no new lesions. SD was defined as neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for PD, taking as reference the smallest sum diameters while on study. PD was defined as at least 20% increase in the sum of diameters of target lesions compared to smallest sum of diameters on-study and absolute increase of at least 5 mm, progression of existing non-target lesions, or presence of new lesions.

Time frame: Cycle 3 Day 15, Cycle 6 Day 15 and at Month 6

Population: ITT set

Disease progression was assessed according to RECIST criteria v1.1. Disease progression was defined as at least a 20% increase in the sum of diameters of target lesions compared to smallest sum of diameters on-study and absolute increase of at least 5 mm, progression of existing non-target lesions, or presence of new lesions.

Time frame: Baseline; Day 15 of Cycles 3 and 6; Month 6 and then every 3 months until disease progression, death, or consent withdrawal (up to 53 months)

Population: ITT set

PFS was defined as the interval between the date of randomization and the first documentation of progressive disease or death from any cause. Disease progression was assessed according to RECIST criteria v 1.1. Disease progression was defined at least 20% increase in the sum of diameters of target lesions compared to smallest sum of diameters on-study and absolute increase of at least 5 mm, progression of existing non-target lesions, or presence of new lesions. PFS was estimated using Kaplan Meier method.

Time frame: Baseline; Day 15 of Cycles 3 and 6; Month 6 and then every 3 months until disease progression, death, or consent withdrawal (up to 53 months)
