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.
|Eligible Ages||18 Years and Over|
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.

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)
Patients with at least a 1cm3 contrast-enhancing lesion suspicious for GBM (either newly-diagnosed or 1st /2nd/ 3rd recurrence of GBM) on a standard-of-care (SOC) brain MRI scan. If the patient undergoes a biopsy or resection for GBM (either newly-diagnosed or 1st /2nd/ 3rd recurrence of GBM) then the remaining contrast-enhancing lesion is at least 1cm3 in size on the post-operative scan. These patients will undergo one [18F]DASA 23 PET/MRI scan before the initiation of therapy, and a second/final [18F]DASA 23 PET/MRI scan within 2-6 weeks after initiation of therapy for their GBM.
Active Comparator: Group IV ([18F]DASA-23, PET)
Healthy volunteers receive [18F]DASA-23 IV and undergo brain PET/MRI brain scan for 60 mins
Drug: - Fluorine F 18 DASA-23
Procedure: - Positron Emission Tomography
Undergo PET scan
