A Study Comparing Abemaciclib Plus Temozolomide to Temozolomide Monotherapy in Children and Young Adults With High-grade Glioma Following Radiotherapy

Study Purpose

The purpose of this study is to measure the benefit of adding abemaciclib to the chemotherapy, temozolomide, for newly diagnosed high-grade glioma following radiotherapy. Your participation could last approximately 11 months and possibly longer depending upon how you and your tumor respond.

Recruitment Criteria

Accepts Healthy Volunteers Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms	No
Study Type An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes. An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes. Searching Both is inclusive of interventional and observational studies.	Interventional
Eligible Ages	0 Years - 20 Years
Gender	All

Exclusion Criteria:

Participants are excluded if any of the following apply:

- Diffuse Intrinsic Pontine Glioma (DIPG) or diffuse midline glioma located in the pons.

- Recurrent or refractory HGG including any recurrence/progression during/after radiotherapy.

- Secondary HGG, defined as a previously treated low-grade glioma that now meets high- grade criteria, or that resulted from a previously treated malignancy.

- Have known pathogenic somatic mutations appropriate for an anaplastic lymphoma kinase (ALK), B-rapidly accelerated fibrosarcoma (BRAF), or neurotrophic tyrosine receptor kinase (NTRK ) inhibitor, in regions where these therapies are available and deemed appropriate by the investigator.

- Prior HGG treatment (including bevacizumab), except for surgery and radiotherapy (with or without concomitant temozolomide).

- Current enrollment in another trial deemed incompatible with this study.

- Treatment with an investigational product within the last 30 days or 5 half-lives (whichever is longer).

- Prior malignancy within the previous 3 years that, per the investigator and the medical monitor, may affect interpretation of study results.

- A preexisting medical condition(s) that, per the investigator, would preclude study participation.

- Any serious, active, systemic infection requiring IV antibiotic, antifungal, or antiviral therapy, including acute hepatitis B or C, or Human Immunodeficiency Virus at C1D1.

- Intolerability or hypersensitivity such as urticaria, anaphylaxis, toxic necrolysis, and/or Stevens-Johnson syndrome to temozolomide, and/or abemaciclib, their excipients, or dacarbazine.

- Received a live virus vaccine within 28 days of C1D1.

- Pregnant, breastfeeding, or intend to become pregnant during the study.

Trial ID: This trial id was obtained from ClinicalTrials.gov, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.	NCT06413706
Phase Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans. Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data. Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs. Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.	Phase 2
