Biodistribution, Dosimetry and Performance of [68Ga]Ga-DOTA-Siglec-9 in Healthy and Patients With Rheumatoid Arthritis, Vasculitis or Pulmonary Sarcoidosis (SIGLEC)
October 19, 2022 updated by: Anne Roivainen, Turku University Hospital
PET/CT Study of Biodistribution and Performance of the [68Ga]Ga-DOTA-Siglec-9 in Patients With Rheumatoid Arthritis,Vasculitis or Pulmonary Sarcoidosis, and Radiation Dosimetry, Pharmacokinetics, Biodistribution, Safety and Tolerability in Healthy Men
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.

Intervention / Treatment
Detailed Description
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.
