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.

Inclusion Criteria: 1. Willing and able to give written informed consent. 2. Males or females aged =18 years old. 3. Good general health as determined by no acute illness and no clinically significant abnormal findings on medical history, vital signs, laboratory tests, or physical examination at screening that, in the opinion of the PI, would interfere with study drug administration, jeopardize the safety of the study participant, or impact the validity of the study results; participants with stable chronic illness are allowed at the discretion of the PI. 4. An interpretable 12-lead ECG with a corrected QT (QTc) interval =450 ms, according to Bazett's formula, without evidence of clinically significant abnormal findings. 5. Normal FEV1/FVC ratio, defined as any value above 0.7 or above the lower 5th percentile of normal AND FEV1 >80% of predicted or above the lower 5th percentile of normal. 6.
