Brief Summary

This is a randomized, double-blind, placebo-controlled phase I clinical study to evaluate the safety, tolerability, pharmacokinetics and immunogenicity of single ascending IV doses of CGB3002 in healthy participants. CGB3002 is being developed to treat Alzheimer's Disease.

Total bilirubin (TBIL) \> ULN at screening or Day -2(except in those due to findings consistent with Gilbert's disease). * Estimated creatinine clearance \< 80 mL/ min (Cockroft-Gault equation) at screening or Day-2. * Test positive for syphilis, hepatitis B virus surface antigen (HbsAg), hepatitis B core antibody (HBcAb), hepatitis C virus antibody (HCV-Ab) or HIV antibody at screening. * Urine drug screening positive at screening or Day-2. * Have a head MRI demonstrating either cerebral microhemorrhages, or superficial siderosis, or prior evidence of microhemorrhage, or any other major intracranial pathology. * Still needed or planned to engage in vigorous physical activity or exercise during study participation. * Other conditions deemed inappropriate by the investigator to participate in the clinical trial.
