Brief Summary

The goal of this clinical trial is to assess the safety, tolerability, and pharmacokinetic profiles of Y-3 in healthy adult volunteers in the United States. The main questions it aims to answer are:

• What the pharmacokinetic profiles of single ascending doses of Y-3 (40 mg and 60 mg) in the US healthy adult volunteers?
• If drug Y-3 (40mg and 60 mg) is safe and tolerate in the US healthy adult volunteers. Researchers will compare drug Y-3 (40 mg and 60 mg) to a placebo (a look-alike substance that contains no drug) to see what the pharmacokinetic profiles of single ascending doses of Y-3 (40 mg and 60 mg) in the US healthy adult volunteers and if drug Y-3 (40mg and 60 mg) is safe and tolerate in the US healthy adult volunteers. Participants will:
• Take drug Y-3 (40 mg) or Y-3 (60 mg) or a placebo only once.
• Answer questions regarding your medical history.
• Comply with the study procedures and requests.
• Complete all tests and collections of PK Sampling.
• Must not have any special dietary requirements and be able to consume the food (low-fat) provided by Tranquil Clinical Research during your 4-night stay.
• Must avoid excessive ( \> 8 cups per day) caffeine consumption (i.e. coffee or tea) during your time in the study.
• Must not consume any food or beverage rich in grapefruit, papaya, or mango during your time in the study.
• Must not take any other medications, including traditional Chinese medicines and herbal medicines, during your time in the study.
• Must avoid sexual activity or use non-drug contraceptive measures (i.e. condoms) during your time in the study.
• Female participants must not become pregnant while in the study.
• Must not receive any vaccinations during your time in the study.
• Must not donate blood for purposes outside of study procedures during your time in the study.
• Must not drink alcohol during your time in the study.

EXPERIMENTAL

The investigational drug (Y-3) consists of two parts: Y-3 for injection (lyophilized powder) （20 mg）and Solvent for Y-3 for injection (concentrated solution)（3ml (containing 0.6 g propylene glycol)）. Subjects will receive Y-3 or placebo on the morning of the dosing day. Drinking water is prohibited from 1 hour before administration until the end of dosing, and subjects may have meals 4 hours after administration. Using a sterile syringe, withdraw dedicated solution into the lyophilized powder vial of Y-3 or placebo. Shake the vial manually until the powder is dissolved.
