| Secondary | Time to Tumor Response (TTR) and Intracranial TTR (Phase 1) | Time to tumor response (TTR) was defined as the time from the first dose of study treatment to the first documentation of objective tumor response (CR or PR). For participants whose objective response proceeded from PR to CR, the onset of PR was taken as the onset of response. TTR was only calculated for the subgroup of participants with a confirmed objective tumor response. Intracranial TTR was only calculated for participants with confirmed intracranial objective response. Results presented here were based on independent central review. | 3 years | |
| Secondary | Duration of Response (DOR) and Intracranial DOR (Phase 1) | Duration of Response (DOR) was defined as the time from the first documentation of objective tumor response (CR or PR) to the first documentation of disease progression or to death due to any cause, whichever occurred first.

The time to first event being a Competing Event (either "CNS progression" or "non CNS progression" or "Death") was defined as time from first dose until the date of that specific event. Participants not known to have any of the Competing Events were censored on the date they were last assessed for disease status for PFS. Participants who presented one type of event were counted as a competing cause of failure for the analysis of other type of events. For each type of event, the cumulative incidence function corresponding to the nearest time point preceding 1 year is presented. The results are based on independent central review. | 3 years | |
| Secondary | Progression-Free Survival (PFS) (Phase 1) | PFS was defined as the time from the first dose of study treatment to the first documentation of objective disease progression or to death on study due to any cause, whichever came first.

| Secondary | Change From Baseline in Total Scores for Detection Test (Cognitive Function Assessment) (Phase 2) | 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. | Baseline, Day 1 of Cycles 2-5, Day 1 of every other cycle from Cycle 6, and end of treatment (up to 3 years) | |
| Secondary | Change From Baseline in Total Scores for Identification Test (Cognitive Function Assessment) (Phase 2) | 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. | Baseline, Day 1 of Cycles 2-5, Day 1 of every other cycle from Cycle 6, and end of treatment (up to 3 years) | |
| Secondary | Change From Baseline in Total Scores for One Back Test (Cognitive Function Assessment) (Phase 2) | 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. | Baseline, Day 1 of Cycles 2-5, Day 1 of every other cycle from Cycle 6, and end of treatment (up to 3 years) | |
| Secondary | Change From Baseline in Total Scores for International Shopping List Test (Cognitive Function Assessment) (Phase 2) | 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. | Baseline, Day 1 of Cycles 2-5, Day 1 of every other cycle from Cycle 6, and end of treatment (up to 3 years) | |
| Secondary | Change From Baseline in Total Scores for International Shopping List Test-Delayed Recall (Cognitive Function Assessment) (Phase 2) | 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. | Baseline, Day 1 of Cycles 2-5, Day 1 of every other cycle from Cycle 6, and end of treatment (up to 3 years) |
