Brief summary

The purpose of this study is to test whether it is safe to give Galinpepimut-S and Nivolumab together in patients with mesothelioma.

Interventions

BIOLOGICALGalinpepimut-S

Galinpepimut-S will be administered alone on weeks 0 and 2. Participants will receive the galinpepimut-S vaccine and nivolumab over 16 weeks in the initial treatment phase.

DRUGNivolumab

Participants will receive nivolumab and the galinpepimut-S vaccine over 16 weeks in the initial treatment phase.

BIOLOGICALSargramostim
