What this trial studies

This phase II trial evaluates the effectiveness of vismodegib, a FAK inhibitor (GSK2256098), capivasertib, and abemaciclib in patients with progressive meningiomas. The study focuses on patients with specific genetic mutations, including SMO, PTCH1, NF2, AKT1, PIK3CA, and PTEN. Participants are assigned to treatment arms based on their mutation status, with the primary goal of assessing progression-free survival and response rates over a six-month period. Secondary objectives include overall survival and monitoring adverse events associated with the treatments.

Who should consider this trial

Good fit: Ideal candidates include patients with histologically proven intracranial meningiomas that are progressive or residual, particularly those with specific genetic mutations.

Not a fit: Patients without the specified genetic mutations or those with non-progressive meningiomas may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide new targeted treatment options for patients with progressive meningiomas, potentially improving survival rates.

How similar studies have performed: Other studies have shown promise with targeted therapies in treating various cancers, suggesting potential success for this novel approach in meningiomas.
