Sequential Dose-escalation Study to Assess the Safety, Tolerability and Pharmacokinetics of TB006 in Healthy Subjects

The TB006 nonclinical pharmacology program establishes its potential as a therapeutic agent for AD. Overall, the data suggest the potential for beneficial therapeutic effects of TB006 in addressing underlying pathology and ameliorating the course of AD. The preclinical safety profile of TB006 further supports the clinical investigation of TB006. This is a Phase 1 SAD study in healthy adult subjects. The study will evaluate the safety, tolerability, and PK of single doses of TB006, administered as an IV infusion over 1 hour.
