- Brief Summary
This is a Phase 1, single-center, open-label, single-arm, dose-escalation positron emission tomography study to assess the safety and tolerability, immunogenicity, Pharmacokinetics, dosimetry, and biodistribution after GEH200521 (18F) Injection is co-administered with GEH200520 Injection in healthy volunteers.
The estimated study duration for each subject is approximately 28 days.
The primary study objective is to evaluate the safety and tolerability of the IMPs, the selected mass doses of GEH200520 Injection co-administered with a fixed dose of GEH200521 (18F) Injection.
