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 - 70 Years|
- - Healthy 18-70 year-old men.
- - Male or female 18-70 year-old patients with active rheumatoid arthritis, vasculitis or pulmonary sarcoidosis.
- - In healthy: ongoing infection/inflammation proven by blood or other tests.
- - In patients with rheumatoid arthritis: no treatment with disease-modifying anti-rheumatic drugs or biologic agents, and no corticosteroids for 2 weeks prior the study.
- - In patients with vasculitis: no immunosuppressives, and glucocorticoid less than 60 mg for 2 weeks or NSAIDs for 1 day prior the study.
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.

Vascular adhesion protein 1 (VAP-1) is an inflammation inducible endothelial cell molecule mediating leukocyte trafficking from blood into the sites of inflammation. Although VAP-1 plays important role in early phases of inflammation, its luminal expression on the endothelium will remain constant if the inflammation continues, which suggest VAP-1 as a promising target for molecular imaging of inflammation. We have previously shown that sialic acid-binding immunoglobulin-like lectin 9 (Siglec-9) is a VAP-1 ligand, and the gallium-68 labeled 1,4,7,10-tetraazacyclododecane-N,N´,N´´,N´´´-tetraacetic acid conjugated peptide ([68Ga]Ga-DOTA-Siglec-9) containing residues 283-297 from Siglec-9 can be used for PET imaging of inflammation in various experimental models. This first-in-human study evaluates safety, tolerability, biodistribution and performance of [68Ga]Ga-DOTA-Siglec-9 after single intravenous injection in six healthy volunteers, and in ten patients with active rheumatoid arthritis (RA), five patients with vasculitis and five patients with pulmonary sarcoidosis.
