Evaluation of Safety, Tolerability, PK/PD, and Metabolism of Single-Dose Singletine(DC407) in Adults
- Registration Number
- NCT06160401
- Lead Sponsor
- Guangzhou JOYO Pharma Co., Ltd
- Brief Summary
The goal of this clinical trial is to evaluate the safety, tolerability and pharmacokinetic characteristics of Singletine in healthy adult subjects. The main questions it aims to answer are: safety and tolerability of Singletine in healthy subjects, the pharmacokinetic characteristics after single and multiple doses and the effect of food on the pharmacokinetic characteristics. Participants will be treated with Singletine orally and safety and pharmacokinetic evaluations will be conducted according to the protocol.
- Detailed Description
This study will be an double-blinded, single-center phase I clinical trial. After being informed about the study and potential risks, all subjects giving written informed consent will undergo a 2-week screening period to determine eligibility for study entry. And then subjects will be administered for single-dose treatment or 7-day multiple-dose treatment and 9-day safety follow up after the last dose of treatment. The safety and pharmacokinetic measures will be conducted according to the protocol.
