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

ClinConnect Summary

This clinical trial is looking to see if adding a medication called abemaciclib to the standard chemotherapy treatment, temozolomide, can help children and young adults with high-grade glioma—a type of brain tumor—after they have received radiation therapy. The trial is open to all genders and includes participants aged from newborns to young adults. To be eligible, participants must have a confirmed diagnosis of high-grade glioma and must have started radiation therapy within a certain time frame after diagnosis. They should also be able to tolerate the treatment and undergo necessary medical tests, like blood draws and MRI scans.

If you or your child decide to participate, the study could last about 11 months, depending on how well the treatment works. Participants will receive close medical supervision and regular assessments to monitor their health and response to the treatment. It’s important to know that certain health conditions or previous treatments might prevent eligibility, so discussing any concerns with a doctor is essential. This trial offers a chance to contribute to research that may help improve treatment options for high-grade glioma in the future.

• • Glioblastoma
• OR as defined by the 2021 WHO Classification Criteria as molecularly characterized:
• • Non-pontine diffuse midline glioma, H3 K27-altered,
• • Diffuse hemispheric glioma, H3 G34-mutant
• • Diffuse pediatric HGG, H3/IDH-wildtype
• • Infant-type hemispheric glioma
• • High-grade astrocytoma with piloid features
• • High-grade pleomorphic xanthoastrocytoma

• • IDH-mutant and 1p/19q co-deleted oligodendroglioma
• • IDH-mutant astrocytoma with homozygous CDKN2A/B deletion
• • Contraceptive use should be consistent with local regulations for participants in clinical studies.
• • Radiotherapy initiated within 6 weeks (+1 week) of diagnosis and administered over 6 weeks (±1 week). Participants \<3 years of age, considered not suitable for radiotherapy may be eligible.
• • Minimum of 4 weeks between completion of radiation and Cycle 1 Day 1 (C1D1).
• • Maximum of 8 weeks between completion of radiation and C1D1. Exceptional circumstances can be discussed with the medical monitor.
• • Acute effects of prior therapies must be Grade ≤1 unless deemed clinically insignificant by the investigator.
• • Adequate hematologic and organ function ≤7 days prior to C1D1
• • Life expectancy of ≥8 weeks and deemed likely to complete at least 1 cycle of treatment.
• * A performance score of ≥60 using:
• • 1. Lansky scale for participants \<16 years
• • 2. Karnofsky scale for participants ≥16 years
• • Able to swallow and/or have a gastric/nasogastric tube.
• • Any current systemic steroid use dose must be stable or decreasing at least 7 days prior to C1D1.
• • Able and willing to adhere to study procedures, including frequent blood draws and MRI.
• • At least 28 days since any major surgery, laparoscopic procedure, or a significant traumatic injury.
• • Has a body surface area (BSA) of ≥0.2 m2.
• 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.
