Cyclin-Dependent Kinase (CDK)4/6 Inhibitor Abemaciclib for Neurofibromatosis Type I (NF1) Related Atypical Neurofibromas
NCT04750928 · View on ClinicalTrials.gov ↗
Study Summary
Background: NF1 is a genetic disease that causes tumors called atypical neurofibromas. These tumors, which arise from nerves, can cause serious medical problems. The only treatment is surgery. Researchers want to see if a drug called abemaciclib can help. Objective: To find a safe, tolerable dose of abemaciclib for treating atypical neurofibromas. Eligibility: People ages 12 and older who have NF1 and have one or more atypical neurofibromas that cannot or will not be removed with surgery Design: Participants will be screened with: Medical history and physical exam Blood, urine, and heart tests MRI: Participants will lie in a machine that takes pictures of the body. A padding or coil will be placed around their head. They may have a contrast agent injected into a vein. Biopsy sample: A small piece of tumor will be removed using a large needle. Participants will have frequent visits during the study. These will include repeats of the screening tests as well as the following: PET scan: Participants will lie in a machine that takes pictures of the body. They will have a contrast agent injected into their arm. Questionnaires about the effects of abemaciclib on pain and quality of life Possible photographs of tumors Participants will take abemaciclib capsules orally twice daily in 28-day cycles. They will take the drug for up to 2 years. Some may be able to take it for longer. Participants will have a follow-up visit about 30 days after their last dose of the study drug. Then they will have visits every 3 months for 1 year.

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT04750928
The ClinicalTrials.gov registry entry for NCT04750928 describes a study currently listed as recruiting. It is categorized as Phase 1, which is the standard way researchers label where a study sits along the investigational pathway from early safety work through later efficacy and post-marketing evaluation. The registered enrollment target is 55 participants, a figure that helps gauge the scale of data the investigators plan to collect. The listed sponsor is National Cancer Institute (NCI), which has 2,390 total studies on file at ClinicalTrials.gov, and sponsors are the parties responsible for study design, oversight, and regulatory filings.
The record links to 1 condition, with Neurofibromatosis 1 appearing as the primary indexed condition, and to 1 intervention — of which Abemaciclib is the first listed. Interventions can include drugs, devices, procedures, behavioral programs, or observational arms, and each is tracked as a separate registry field so that downstream queries can filter accurately. When a trial lists multiple interventions, it usually reflects a multi-arm design or a comparison protocol rather than a single treatment being tested in isolation. The brief summary published in the registry is the clearest source of protocol intent and should be read before drawing conclusions from any sidebar tags.
Geographic footprint matters for practical reasons: NCT04750928 reports 1 study location spanning 1 distinct geographic area — top geographies include Maryland. A larger site network tends to correlate with broader recruitment capacity, but it does not imply anything about study quality, and site-level enrollment status can diverge from the overall registry status shown above. Every data point on this page comes from the public ClinicalTrials.gov dataset and is reproduced here for reference only; it is not a medical recommendation, an endorsement of the sponsor, or an invitation to enroll.
