Study Overview

This clinical trial focuses on testing the efficacy of different digital interventions to promote re-engagement in cancer-related long-term follow-up care for adolescent and young adult (AYA) survivors of childhood cancer.

Description

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. * Must not smoke during your time in the study. * Inform your Study Doctor if you no longer wish to participate in the study.

Known allergy to Y-3 or any of its excipients. 2. Have disease history or current disease that may affect the safety evaluation of the subject or the internal process of the study drug, that the investigator judged to be of clinical significance, including the cardiovascular system, endocrine system, central nervous system, digestive system, respiratory system, hematological system, immunology, psychiatry, metabolic abnormalities, etc. 3. Clinically significant abnormal 12-lead electrocardiograms (ECG) and vital signs judged by the investigator. 4.
