Abemaciclib in Newly Diagnosed Meningioma Patients
- Registration Number
- NCT05940493
- Lead Sponsor
- Nader Sanai
- Brief Summary
This study is being done to learn about how an investigational drug called abemaciclib works in treating patients with a newly-diagnosed grade 3 meningioma. Abemaciclib is a drug that is approved by the FDA, but not for brain tumors.
Participants who consent to the trial will have surgical tissue collected from the planned surgical resection and tested. If the tissue shows positive results for RB cells and participants are qualified, they will be enrolled and receive study treatment two to five weeks after completing standard-of-care radiation therapy.
This is a randomized clinical trial which means that participants will be randomly assigned to a treatment based on chance, like a flip of a coin. Neither the participant nor the researcher chooses the assigned group. Randomization will help the researchers study how the drug works by comparing the difference between the study drug and the placebo and how they work in treating brain tumors. This is a double-blinded study, which means that neither the participant nor the study team will know which treatment the participant is receiving.

- Participant with an intracranial WHO Grade 3 meningioma or lower grade meningioma that has progressed to WHO grade 3 that have received prior radiation therapy.
- Resected tissue must demonstrate: (a) RB positivity on immunohistochemistry (IHC); or, no RB mutations on next-generation sequencing (NGS).
- A washout period of 14 to 35 days is required between end of RT and Day 1 and must be fully recovered from the acute effects of RT.
- Ability to understand and the willingness to sign a written informed consent document (personally or by the legally authorized representative, if applicable).

- Participant has adequate bone marrow and organ function
- Confirmed negative serum pregnancy test (β-hCG) before starting study treatment or participant who is no longer of childbearing potential due to surgical, chemical, or natural menopause.
- For females of reproductive potential: use of highly effective contraception during study participation and for an additional 3 weeks after the end of treatment administration.
- For males of reproductive potential: use of condoms or other methods to ensure effective contraception with partner and for an additional 3 weeks after the end of treatment administration.
- Prior history of cancer with ongoing treatment of disease.
- Current use of coumarin-derived anticoagulant for treatment, prophylaxis or otherwise. Therapy with heparin, low molecular weight heparin (LMWH) or fondaparinux is allowed.

- Known allergic reactions to components of the abemaciclib.
- Active infection or fever >38.5°C requiring systemic antibiotic, antifungal or antiviral therapy within 4 weeks of Day 1.
- Known to have active (acute or chronic) or uncontrolled severe infection, liver disease such as cirrhosis, decompensated liver disease, and active and chronic hepatitis.
- Known active systemic bacterial infection, fungal infection, or detectable viral infection .
- Participant has serious and/or uncontrolled preexisting medical condition(s) that, in the judgment of the investigator, would preclude participation in this study.
- Prior therapy with any CDK4/6 inhibitor.
- Treatment with another investigational drug within 5 half-lives of the investigational product.
- The patient has a personal history of any of the following conditions: syncope of cardiovascular etiology, ventricular arrhythmia of pathological origin (including, but not limited to, ventricular tachycardia and ventricular fibrillation), or sudden cardiac arrest.
