18F-FPPRGD2 PET/CT or PET/MRI in Predicting Early Response in Patients With Cancer Receiving Anti-Angiogenesis Therapy

PRIMARY OBJECTIVE • Evaluate 18F-FPPRGD2 and 18F-FDG as PET/CT or PET/MRI radiotracers for imaging prediction and assessment of response to anti-angiogenesis therapy in participants with glioblastoma multiforme (GBM), gynecological cancers, and renal cell carcinoma (RCC). SECONDARY OBJECTIVE • Progression-free survival (PFS) at up to 1 year after initial scans and treatment OUTLINE: Patients undergo 18F-FPPRGD2 and 18F-FDG PET/CT or PET/MRI medical imaging at baseline and at regular medical care follow-up (6 to 12 weeks). After completion of study imaging, patients are followed up at 12 months.
