AI summary: who the study is looking for
From the trial's eligibility criteria. Machine-read from the registry text on this page, so it can be wrong. The registry text below and the trial team decide who can take part.
The trial is looking for healthy men and for men and women with active rheumatoid arthritis, vasculitis or pulmonary sarcoidosis. Everyone gets one injection of the PET tracer [68Ga]Ga-DOTA-Siglec-9.
- Age
- 18 to 70 years
- Sex
- Healthy volunteers: men only. Patients: men and women.
- Disease stage
- Patients must have active rheumatoid arthritis, vasculitis or pulmonary sarcoidosis.
- Earlier treatment
- Rheumatoid arthritis: no disease-modifying anti-rheumatic drugs or biologic agents, and no corticosteroids for 2 weeks before the study. Vasculitis: no immunosuppressives, and glucocorticoid less than 60 mg for 2 weeks or NSAIDs for 1 day before the study. Pulmonary sarcoidosis: no corticosteroids for 1 week or NSAIDs for a day before the study.
Main reasons for not taking part
- Healthy volunteers: ongoing infection or inflammation shown by blood or other tests
- Rheumatoid arthritis: treatment with disease-modifying anti-rheumatic drugs or biologic agents
- Rheumatoid arthritis: corticosteroids in the 2 weeks before the study
- Vasculitis: immunosuppressives
- Pulmonary sarcoidosis: corticosteroids in the 1 week before the study

This study evaluates safety, tolerability, biodistribution and performance of the [68Ga]Ga-DOTA-Siglec-9 following a single intravenous administration in patients with active rheumatoid arthritis, vasculitis or pulmonary sarcoidosis as well as radiation dosimetry, plasma pharmacokinetics, biodistribution, safety and tolerability of the tracer in healthy volunteers.
Inclusion: Healthy 18-70 year-old men; Male or female 18-70 year-old patients with active rheumatoid arthritis, vasculitis or pulmonary sarcoidosis.
Exclusion: 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; In patients with pulmonary sarcoidosis: no corticosteroids for 1 week or NSAIDs for day prior the study; In healthy: ongoing infection/inflammation proven by blood or other tests.
