Eligibility Criteria
Potential participants will first be screened using the screening inclusion/exclusion shown below. If they meet the requirements of the screening phase, they will then be evaluated for enrollment based on the overall study's inclusion criteria as well as the stratum-specific inclusion/exclusion criteria for the applicable stratum, all of which are shown below.
SCREENING INCLUSION CRITERIA - ALL PARTICIPANTS:
- Participants with recurrent, progressive, or refractory brain tumors.
- Age ≥ 1 year and < 25 years at the time of screening. Exception: Participants with recurrent, progressive, or refractory Medulloblastoma and are ≥ 1 and < 40 years of age at the time of study screening are eligible for screening.
- Participants and/or guardian have the ability to understand and the willingness to sign a written informed consent document according to institutional guidelines.
SCREENING EXCLUSION CRITERIA - ALL PARTICIPANTS:
- Participants with a diagnosis of recurrent, progressive, or refractory low grade glioma (LGG).
- Previous exposure to a CDK4/6 inhibitor (palbociclib, abemaciclib, or ribociclib).
- Participants with a history of clinically significant, uncontrolled heart disease and/or repolarization abnormalities.
- Participants with any history of QTc prolongation (i.e. QTc interval of > 450 msec).
Participants who meet the requirements of the screening phase will then be evaluated for enrollment based on the overall study's inclusion criteria as well as the stratum-specific inclusion/exclusion criteria for the applicable stratum, all of which are shown below.
INCLUSION CRITERIA - OVERALL STUDY - ALL PARTICIPANTS:
