  • Simplified description (AI rewritten)
  • Technical description (Original)

This study is for adults aged 18-60 who are healthy and want to help researchers learn more about how a special compound, called GzmB-targeted [Cu-64]-labeled compound, moves and acts in the body. This compound is used in PET/CT scans, a type of imaging that helps doctors see inside the body. The study involves getting one injection, several scans and tests over 24 hours, and a follow-up phone call a week later.

To join, you must be healthy, not pregnant or breastfeeding, and able to have scans and tests. You should also not have any infections or serious illnesses, and must not have had major surgery recently. You will need to agree to use birth control if you are of childbearing potential or have a partner who is.

  • The study lasts about 24 hours, with a follow-up call at Day 7.
  • Participants will undergo multiple PET/CT scans and tests.
  • Up to 12 healthy volunteers will take part.
