Researchers are evaluating the effects of several targeted drugs—vismodegib, FAK inhibitor GSK2256098, capivasertib, and abemaciclib—on patients with progressive meningiomas that have specific genetic mutations. This phase II trial focuses on tumors that are growing, spreading, or worsening despite prior treatment. The study aims to measure how well these drugs work in slowing tumor progression and improving response rates, especially in patients whose tumors have mutations in SMO, PTCH1, NF2, AKT1, PIK3CA, PTEN, and CDK-related pathways. Patients are assigned to one of four treatment groups based on their tumor's genetic mutation profile. Those with SMO or PTCH1 mutations receive vismodegib daily by mouth, those with NF2 mutations receive the FAK inhibitor GSK2256098 twice daily, patients with AKT1, PIK3CA, or PTEN mutations take capivasertib twice daily for four days each week, and those with CDK pathway alterations receive abemaciclib every 12 hours. Each treatment cycle is 28 days, continuing unless the disease worsens or side effects become unacceptable. After treatment ends, patients are followed every six months for up to five years. Participants undergo various assessments including imaging scans and genetic testing to confirm eligibility and monitor tumor status. Researchers track progression-free survival at six months and response rates up to two years. Safety is monitored through adverse event reporting and lab tests. The study also collects data on overall survival and treatment tolerability. Patients are carefully evaluated before and during treatment to ensure safety and measure the drugs' effects on tumor growth and patient health over time.
