Brief Summary

This study is 'A Randomized Phase 1 Double Blind Placebo Controlled, Single-Dose, Dose-Escalation Study to Evaluate the Safety, Tolerability and Pharmacokinetics of Orally Inhaled Aerosolized Hydroxychloroquine Sulfate in Healthy Adult Volunteers.' The primary objectives are as follows:

• To assess the safety and tolerability of AHCQ administered as a single dose by oral inhalation in healthy individuals at escalating doses until either the maximum tolerated dose (MTD) is identified or 1 mL of a 50 mg/mL solution is administered.
• To determine the recommended Phase 2a dose (RP2D). Secondary objectives:
• To characterize pharmacokinetics (PK) of single dose AHCQ in healthy individuals.

Model Details: This is a randomized, double-blind placebo-controlled Phase 1 single-dose dose-escalation study to assess the safety, tolerability and PK of oral inhalation of AHCQ in healthy participants. A sentinel dose strategy will be employed and the decision to escalate to the next dose level, or deescalate or stop the study, will be based on review and analysis of all available blinded safety and tolerability data by the Safety Review Committee (SRC), which will make a recommendation to the Sponsor and the Sponsor will inform the PI of the recommendation.
