  42. Overall Survival (Phase 2) [ Time Frame: 3 years ]
    OS was defined as the time from first dose to the date of death due to any cause. For participants still alive at the time of analysis, the OS time was censored on the last date the participants were known to be alive. Estimates of OS and its 95% confidence interval were determined using Kaplan-Meier method.

    Clearance of a drug is a measure of the rate at which a drug is metabolized or eliminated by normal biological processes. CL/F was calculated as dose/AUCinf, where AUCinf was the area under the plasma concentration-time profile from time 0 extrapolated to infinite time.

  48. Apparent Volume of Distribution (Vz/F) of PF-06463922 (Phase 2) [ Time Frame: Pre-dose, 0.5, 1, 2, 3, 4, 6, 8, 9, 24, 48, 72, 96 and 120 hours post-dose on Day -7 ]
    Vz/F was defined as the theoretical volume in which the total amount of drug would need to be uniformly distributed to produce the desired plasma concentration of a drug, and calculated as dose/(AUCinf*kel), where AUCinf was the area under the plasma concentration-time profile from time 0 extrapolated to infinite time, kel was the rate constant for terminal phase.

  49. Terminal Half-Life of PF-06463922 (Phase 2) [ Time Frame: Pre-dose, 0.5, 1, 2, 3, 4, 6, 8, 9, 24, 48, 72, 96 and 120 hours post-dose on Day -7 ]
    Terminal plasma half-life was defined as the time measured for the plasma concentration to decrease by one half, and calculated as loge(2)/kel, where kel was the rate constant for terminal phase.

  50. Observed Accumulation Ratio (Rac) of PF-06463922 Following Multiple Oral Doses (Phase 2) [ Time Frame: Pre-dose, 0.5, 1, 2, 3, 4, 6, 8, 9 and 24 hours post-dose on Cycle 1 Day 15 ]
    Rac was calculated as Day 15 AUCtau/Day -7 AUCtau, where AUCtau was the area under the plasma concentration-time profile from time 0 to time tau (24 hours for QD dosing regimen which was adopted in Phase 2).

  51. Steady State Accumulation Ratio (Rss) of PF-06463922 Following Multiple Oral Doses (Phase 2) [ Time Frame: Pre-dose, 0.5, 1, 2, 3, 4, 6, 8, 9 and 24 hours post-dose on Cycle 1 Day 15 ]
    Rss was calculated as Day 15 AUCtau/Day -7 AUCinf, where AUCtau was the area under the plasma concentration-time profile from time 0 to time tau (24 hours for QD dosing regimen which was adopted in Phase 2), and AUCinf was the area under the plasma concentration-time profile from time 0 extrapolated to infinite time.

  54. Number of Participants Who Improved, Worsened or Remained Stable in EORTC QLQ-C30 (Phase 2) [ Time Frame: 3 years ]
    European Organisation for Research and Treatment of Cancer Core Quality of Life Questionaires (EORTC QLQ)-C30 (version 3.0) consists of 30 questions assessing 5 functional domains (physical, role, emotional, cognitive and social), global quality of life (QoL), disease/treatment related symptoms (fatigue, nausea/vomiting, pain, dyspnea, insomnia, appetite loss, constipation and diarrhoea), and the perceived financial impact of disease. Each scale was transformed to a range of 0 to 100 using standard EORTC algorithm. For global QoL and functional scales, higher score indicate better performance, and improvement was defined as an increase of at least 10 points, worsening was defined as a decrease of at least 10 points. For symptom scales, higher score indicates worse symptoms, and improvement was defined as a decrease of at least 10 points, worsening was defined as an increase of at least 10 points. All scales which had not improved nor worsened were considered stable.

  55. Number of Participants Who Improved, Worsened or Remained Stable in EORTC QLQ-LC13 (Phase 2) [ Time Frame: 3 years ]
    EORTC QLQ-LC13 is the lung cancer module of EORTC QLQ-C30 and includes questions specific to the disease associated symptoms (dyspnea, cough, hemoptysis, and site specific pain), treatment-related symptoms (sore mouth, dysphagia, neuropathy and alopecia), and analgesic use of lung cancer patients. The scale was transformed to a range of 0 to 100 using standard EORTC algorithm. Higher score indicates worse symptoms, and improvement was defined as a decrease of at least 10 points, worsening was defined as an increase of at least 10 points. All scales which had not improved nor worsened were considered stable.

  56. Number of Participants With Treatment-Emergent Adverse Events (Phase 1 and Phase 2) [ Time Frame: 3 years ]
    AE was defined as any untoward medical occurrence in a clinical investigation participant administered a product or medical device, regardless of the causal relationship to study treatment. Treatment-emergent AEs (TEAEs) were defined as AEs which occurred for the first time during the effective duration of treatment or AEs that increased in severity during treatment. Serious AEs (SAEs) were defined as any untoward medical occurrence at any dose that resulted in death; was life-threatening (immediate risk of death); required inpatient hospitalization or caused prolongation of existing hospitalization; resulted in persistent or significant disability/incapacity (substantial disruption of the ability to conduction normal life functions). AEs included SAEs and non-serious AEs. Causality to study treatment was determined by the investigator. Severity was graded according to National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE) version 4.03.

  57. Number of Participants With Laboratory Abnormalities (Phase 1 and Phase 2) - Hematology [ Time Frame: 3 years ]

    Blood pressure (BP), including systolic BP (SBP) and diastolic BP (DBP), and pulse rate were recorded in sitting position. Body weight was also measured.

  61. Number of Participants With Maximum Decrease From Baseline Greater Than or Equal to 20 Percent in Left Ventricular Ejection Fraction (LVEF) (Phase 1 and Phase 2) [ Time Frame: Baseline, Day 1 of Cycles 2-3, Day 1 of every other cycle from Cycle 5 up to 18 months for Phase 1 (up to 30 months for Phase 2), every 4 cycles thereafter, and end of treatment (up to 3 years) ]
    Left Ventricular Ejection Fraction (LVEF) was determined by electrocardiogram (ECG) measurement. Baseline was defined as the measurement prior to the first dose of study treatment.

  62. Number of Participants With Absolute Values and Change From Baseline in QTcF Meeting Pre-defined Criteria (Phase 1 and Phase 2) [ Time Frame: Phase 1: baseline, Days 1, 8 and 15 of Cycle 1, Day 1 of Cycles 2-25, end of treatment (up to 3 years); Phase 2: baseline, Days 1, 8 and 15 of Cycle 1, Day 1 of Cycles 2-5, end of treatment (up to 3 years) ]
    Triplicate 12-lead electrocardiograms (ECGs) were performed approximately 2 minutes apart to determine mean QTc interval (QT interval corrected for heart rate). QT interval was corrected for heart rate using Fridericia's formula to provide QTcF. Absolute values and changes from baseline were summarized according to pre-defined criteria. Baseline was defined as the last evaluation on or prior to the first dose of study treatment.

  63. Number of Participants With Suicidal Ideation and Suicidal Behavior (Phase 2) [ Time Frame: 3 years ]
    The Columbia Suicide Severity Rating Scale (C-SSRS) was used to analyze participants' suicidal ideation and behavior, and it is a unique, simple and short method of assessing both behavior and ideation that tracks all suicidal events and provides a summary of suicidality. It assesses the lethality of attempts and other features of ideation (frequency, duration, controllability, reasons for ideation and deterrents), all of which are significantly predictive of completed suicide.

  64. Change From Baseline in Total Scores for Beck Depression Inventory (BDI)-II (Mood Assessment) (Phase 2) [ Time Frame: Baseline, Day 1 of Cycles 2-5, Day 1 of every other cycle from Cycle 6, and end of treatment (up to 3 years) ]
    The Beck Depression Inventory (BDI)-II is a 21-item self-report scale, with each item rated by participants on a 4-point scale (ranging from 0-3). The scale includes items capturing mood, (loss of pleasure, sadness, and irritability), suicidal ideation, and cognitive signs (punitive thoughts, self-criticism, self-dislike, pessimism, and poor concentration) as well as somatic signs (appetite, sleep, fatigue and libido). Scores were obtained by adding up the total points from the series of answers. Higher total scores indicate more severe depressive symptoms. The standardized cutoffs are as follows: 0-13: minimal depression; 14-19: mild depression; 20-28: moderate depression; 29-63: severe depression.

  65. Change From Baseline in Total Scores for Detection Test (Cognitive Function Assessment) (Phase 2) [ Time Frame: Baseline, Day 1 of Cycles 2-5, Day 1 of every other cycle from Cycle 6, and end of treatment (up to 3 years) ]
    The Detection Test is a measure of psychomotor function and uses a well validated simple reaction time paradigm with playing card stimuli. In this test, the on-screen instructions ask: "Has the card turned over?". A playing card is presented face down in the center of the screen. The card flips over so it is face up. As soon as the card flips over the participant must press "Yes". The participant is encouraged to work as quickly as they can and be as accurate as possible. The speed and accuracy of each response are recorded and mean of the log10 transformed reaction times for correct responses is calculated. Lower values of least square mean change from baseline indicate performance decline. Upper limit of 95% confidence interval of -0.00 or lower indicate statistically significant decline of performance over baseline at that cycle.

  66. Change From Baseline in Total Scores for Identification Test (Cognitive Function Assessment) (Phase 2) [ Time Frame: Baseline, Day 1 of Cycles 2-5, Day 1 of every other cycle from Cycle 6, and end of treatment (up to 3 years) ]
    The Identification Test is a measure of visual attention and uses a well validated choice reaction time paradigm with playing card stimuli. In this task, the playing cards are all red or black jokers. The on-screen instructions ask: "Is the card red?". A playing card is presented face down in the center of the screen. The card flips over so it is face up. As soon as it flips over the participant must decide whether the card is red or not. If it is red the participant should press "Yes", and if it is not red the participant should press "No". The participant is encouraged to work as quickly and accurately as possible. The speed and accuracy of each response are recorded and mean of the log10 transformed reaction times for correct responses is calculated. Lower values of least square mean change from baseline indicate performance decline. Upper limit of 95% confidence interval of -0.00 or lower indicate statistically significant decline of performance over baseline at that cycle.

  67. Change From Baseline in Total Scores for One Back Test (Cognitive Function Assessment) (Phase 2) [ Time Frame: Baseline, Day 1 of Cycles 2-5, Day 1 of every other cycle from Cycle 6, and end of treatment (up to 3 years) ]
    The One Back Test is a measure of working memory and uses a well validated n back paradigm with playing cards. In this task, the on-screen instructions ask: "Is the previous card the same?". A playing card is presented in the center of the screen. The participant must decide whether the card is the same as the previous card. If it is the same the participant should press "Yes", and if not press "No". The participant is encouraged to work as quickly and accurately as possible. The speed and accuracy of each response are recorded, mean of the log10 transformed reaction times for correct responses is used to demonstrate speed of performance, and the arcsine transformation of the square root of the proportion of correct responses is used to demonstrate accuracy. Lower values of least square mean change from baseline indicate performance decline. Upper limit of 95% confidence interval of -0.00 or lower indicate statistically significant decline of performance over baseline at that cycle.

  68. Change From Baseline in Total Scores for International Shopping List Test (Cognitive Function Assessment) (Phase 2) [ Time Frame: Baseline, Day 1 of Cycles 2-5, Day 1 of every other cycle from Cycle 6, and end of treatment (up to 3 years) ]
    The International Shopping List task is a measure of verbal learning and uses a well validated list learning paradigm administered using a computer. High frequencies, high imagery, concrete nouns (items from a shopping list) were read to the participant at the rate of one word every 2 seconds. Once all 12 words had been read, the participant was asked to recall as many of the words as quickly as possible. The words recalled by the participant were marked on the computer screen. When the participant could recall no more words, the same list was read again. The words recalled by the participant were recorded. This was then repeated a third time. Total number of correct responses on 3 consecutive trials at a single assessment was recorded. Lower values of least square mean change from baseline indicate performance decline. Upper limit of 95% confidence interval of -0.00 or lower indicate statistically significant decline of performance over baseline at that cycle.

  69. Change From Baseline in Total Scores for International Shopping List Test-Delayed Recall (Cognitive Function Assessment) (Phase 2) [ Time Frame: Baseline, Day 1 of Cycles 2-5, Day 1 of every other cycle from Cycle 6, and end of treatment (up to 3 years) ]
    This test was performed in the same way as the International Shopping List Test, with the exception that, the delayed recall condition required the participant to recall the words from the list 15 30 minutes later without having the list read again. During the recognition condition, the qualified personnel read a shopping list item that may or may not have been on the original list and the participant had to respond either affirmatively (if the item was on the original list) or negatively (if it was not). Total number of correct responses made in remembering the word list after a delay was recorded. Lower values of least square mean change from baseline indicate performance decline. Upper limit of 95% confidence interval of -0.00 or lower indicate statistically significant decline of performance over baseline at that cycle.
