The goal of this First in Human Phase 1 clinical trial is to to assess the safety, tolerability, and systemic exposure of single, twice daily (BID) doses and repeated BID doses of ascending dosing by intranasal administration of Apo-Si-K170AC76 in healthy adult subjects. The primary objective is to evaluate the safety and tolerability of single, BID, and repeated BID, ascending dosing of Apo-Si-K170A-C76 administered intranasally (IN) in healthy adult subjects.
The secondary objective is to evaluate the systemic exposure to Apo-Si-K170A-C76 following intranasal administration in healthy adult subjects under the aforementioned administration regimens. Researchers will compare the active drug Apo-Si-K170A-C76 to placebo control.
