Multiparametric Metabolic and Hypoxic PET/MRI Imaging Substudy in Gliomas

Description:

This substudy will investigate a new imaging approach using positron emission tomography (PET) and two investigational drugs (\[18F\]FET and \[18F\]FMISO) to see if the imaging results will help with the placement of catheters for therapy delivery in 20 adult patients with malignant gliomas (MGs) who are participating in the UAB IRB approved main study, A Phase I/II Study of Pembrolizumab and M032 (NSC 733972), a Genetically Engineered HSV-1 Expressing IL-12, in Patients with Recurrent/Progressive and Newly Diagnosed Glioblastoma Multiforme, grade 3 or grade 4 astrocytoma, or Gliosarcoma (IRB 300007756 PI Markert). The PET and MR imaging results will be available to guide catheter placement within IRB 300007756 study-specific guidelines during Neurosurgery.
