| Measure | Time frame | Description |
|---|---|---|
| Progression Free Survival (PFS) Rate at Month 6 | At Month 6 from randomization (Cohort 1) or first day of treatment (Cohorts 2 and 3) | PFS at Month 6 was defined as the percentage of participants who remained alive and progression-free at Month 6, based on investigator's assessment. Progression was defined using Response Assessment in Neuro-Oncology (RANO) criteria, as a greater than 25% increase in enhancing lesions despite stable or increasing steroid dose, an increase (significant) in non-enhancing T2-weighted-Fluid-Attenuated Inversion Recovery (T2/FLAIR) lesions that are not attributable to other non-tumor causes, and any new lesions. PFS rate at Month 6 was estimated from Kaplan-Meier (K-M) product-limit estimate of PFS. |

CR was defined as the disappearance of all enhancing disease (measurable and non-measurable) sustained for at least 4 weeks, no new lesions, and stable or improved non-enhancing (T2/FLAIR) lesions.

Participant flow
Recruitment details
A total of 173 participants were screened and of those, 152 participants were deemed eligible, and 151 received study treatment.
Pre-assignment details
The protocol definition of study completion was that the participant had disease progression. Protocol defined reasons for not completing were adverse event, participant choice, lost to follow-up, administrative/other (including withdrawal of consent, pregnancy, study terminated by sponsor or other). Death was not a protocol defined reason for non-completion. Participants were followed for survival until death, except where they withdrew consent, or the Sponsor stopped the survival follow-up.
