Summary

This trial will test if a combo of pembrolizumab, olaparib, & temozolomide is safe & effective for people with a glioma that didn't respond to previous treatment or came back after treatment.

Who is the study for?
Adults with a glioma brain tumor that's come back or didn't respond to treatment can join. They must be in good physical condition, able to take oral meds, and have no major organ issues. Pregnant women can't participate, and those who can have children must use birth control.
What is being tested?
The trial is testing how safe and effective the combination of pembrolizumab, olaparib, and temozolomide is for treating recurrent gliomas. Participants will receive all three drugs to see if they work better together.
What are the potential side effects?
Possible side effects include immune system reactions, blood cell changes leading to increased infection risk or bleeding problems, fatigue, nausea or vomiting from chemotherapy drugs like temozolomide.

Trial Design

2Treatment groups
Experimental Treatment
Group I: Recurrent enhancing grade II and III IDH-mutated gliomas that have failed previous therapyExperimental Treatment2 Interventions
All patients will receive pembrolizumab for two cycles prior to the addition of olaparib and temozolomide. Combination olaparib and temozolomide will be added in cycle 3. Combination therapy will continue through cycle 11 (cycles 3-11 = 27 weeks or approximately 6 months). Patients will then continue on pembrolizumab maintenance for a maximum of 35 cycles (two years) or until progression of disease or unacceptable toxicity.
Group II: Recurrent IDH-wildtype gliomas and homologous recombination deficiency (HRD).Experimental Treatment2 Interventions
Five patients will receive pembrolizumab for two cycles prior to the addition of olaparib and temozolomide. Combination olaparib and temozolomide will be added in cycle 3. Combination therapy will continue through cycle 11 (cycles 3-11 = 27 weeks or approximately 6 months). Patients will then continue on pembrolizumab maintenance for a maximum of 35 cycles (two years) or until progression of disease or unacceptable toxicity. This cohort will be analyzed descriptively.
