Nivolumab and Multi-fraction Stereotactic Radiosurgery With or Without Ipilimumab in Treating Patients With Recurrent Grade II-III Meningioma


Brief description of study

This phase I/II trial studies the side effects and best dose of nivolumab when given together with multi-fraction stereotactic radiosurgery and to see how well they work with or without ipilimumab in treating patients with grade II-III meningioma that has come back (recurrent). Immunotherapy with monoclonal antibodies, such as nivolumab and ipilimumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Stereotactic radiosurgery is a specialized radiation therapy that delivers a single, high dose of radiation directly to the tumor and may cause less damage to normal tissue. It is not yet known whether giving nivolumab and multi-fraction stereotactic radiosurgery with or without ipilimumab may work better in treating patients with grade II-III meningioma.

Detailed Study Description

PRIMARY OBJECTIVES:

I. To evaluate the maximum tolerated combination and safety profile of multi-fraction radiosurgery with concurrent nivolumab plus or minus ipilimumab for recurrent radiation-relapsed high-grade meningioma. (Phase I) II. To evaluate the objective response rate (ORR) of multi-fraction radiosurgery with concurrent nivolumab plus or minus ipilimumab for recurrent radiation-relapsed high-grade meningioma. (Phase II)

SECONDARY OBJECTIVES:

I. To evaluate duration of overall response, progression-free survival (PFS) and overall survival (OS) of recurrent radiation-relapsed high-grade meningioma patients treated with the combination of multi-fraction radiosurgery and nivolumab plus or minus ipilimumab.

CORRELATIVE OBJECTIVES:

I. To analyze the immunophenotype changes of peripheral T-cells during the treatment with multi-fraction radiosurgery in combination with nivolumab plus or minus ipilimumab.

II. To perform molecular profiling assays on pretreatment/baseline archival tumor, including, but not limited to, whole exome sequencing (WES) and messenger ribonucleic acid (RNA) sequencing (RNAseq), in order to IIa. Identify potential predictive and prognostic biomarkers (such as neoantigen signature or mutation burden) beyond any genomic alteration by which treatment may be assigned.

IIb. Identify resistance mechanisms using genomic deoxyribonucleic acid (DNA)- and RNA-based assessment platforms.

III. To contribute genetic analysis data from de-identified biospecimens to Genomic Data Commons (GDC), a well annotated cancer molecular and clinical data repository, for current and future research; specimens will be annotated with key clinical data, including presentation, diagnosis, staging, summary treatment, and if possible, outcome.

IV. To bank formalin-fixed, paraffin-embedded (FFPE) tissue, blood (for cell-free DNA analysis), and nucleic acids obtained from patients at the Experimental Therapeutics Clinical Trials Network (ETCTN) Biorepository.

OUTLINE: This is a phase I, dose-escalation study of nivolumab followed by a phase II study. Patients are randomized to 1 of 2 cohorts.

COHORT A: Patients receive nivolumab intravenously (IV) over 60 minutes on day 1. Cycles repeat every 28 days for up to 1 year in the absence of disease progression or unacceptable toxicity. Patients also undergo multi-fraction stereotactic radiosurgery on days 1, 3, and 5.

COHORT B: Patients receive nivolumab IV over 60 minutes every 2 weeks for 12 doses (6 months) and then every 4 weeks for additional 6 months. Patients also receive ipilimumab IV over 90 minutes on day 1. Treatment with ipilimumab repeats every 6 weeks for 4 doses in the absence of disease progression or unacceptable toxicity. Patients undergo multi-fraction stereotactic radiosurgery on days 1, 3, and 5.

After completion of study treatment, patients are followed up for 100 days.
