Accepts Healthy Volunteers
Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms
An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes.
An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes.
Searching Both is inclusive of interventional and observational studies.

This trial id was obtained from ClinicalTrials.gov, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.
Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans.
Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data.
Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs.
Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.
The sponsor is the organization or person who oversees the clinical study and is responsible for analyzing the study data.

|Healthy Subject, Intracranial Neoplasm, Recurrent Glioblastoma|
- I. Determine whether the fluorine F 18 DASA-23 ([18F]DASA 23) PET scan signal change from pre-therapy to one week after initiation of therapy can predict the tumor's responsiveness to therapy and 6 month progression free survival (PFS6), in suspected recurrent glioblastoma.
- I. Determine the sensitivity, specificity, and accuracy of [18F]DASA-23 PET imaging in identifying intracranial tumors in patients with intracranial tumors.
- II. Determine whether the [18F]DASA-23 PET scan signal change from pre therapy to one week after initiation of therapy can predict progression free survival (PFS) and overall survival (OS), in suspected recurrent glioblastoma.
Active Comparator: Group I ([18F]DASA-23, PET)
Healthy volunteers receive [18F]DASA-23 IV and undergo brain PET scan over 15 minutes and 4 vertex-to-toe PET scans over 30 minutes each.
Experimental: Group II ([18F]DASA-23, PET)
Intracranial tumor participants receive [18F]DASA-23 IV and undergo brain PET scan over 60 minutes and 1 vertex-to-toe PET scan over 30 minutes.
Experimental: Group III ([18F]DASA-23, PET)
Recurrent glioblastoma participants receive [18F]DASA-23 IV and undergo brain PET scan over 60 minutes and 1 vertex-to-toe PET scan over 30 minutes. Participants undergo second PET scan 7 days after the initiation of therapy.
Drug: - Fluorine F 18 DASA-23
Procedure: - Positron Emission Tomography
Undergo PET scan
