Brief summary

To Evaluate the Tolerability and Pharmacokinetics of LW231 Tablets in Single-center, Randomized, Double-blind, Placebo-controlled Multiple-dose, Single-dose, Multiple-dose Phase Ia Clinical Trials in Healthy Subjects .

Detailed description

The purpose of this study is to evaluate the safety, tolerability, and pharmacokinetics of LW231 tablets in healthy volunteers and in chronic hepatitis B (CHB) patients after single and multiple doses. In addition, the study will evaluate the initial antiviral efficacy of LW231 in CHB patients following a multiple dosing regimen.

Inclusion criteria

1.18-55 years old male or female. 2.Body Mass Index (BMI) between 18 to 28 kg/m2 (inclusive) and body weight equal to or over 45 kg for females and 50kg for males. 3.Healthy status will be defined as the absence of evidence of any active or chronic disease following a detailed medical and surgical history, concomitant drug use (including hormonal supplements), a complete physical examination including vital signs, 12-lead ECG, hematology, blood chemistry, serology, and urinalysis.

Exclusion criteria

1. Any clinically significant abnormalities in laboratory test results at screening. In the case of uncertain or questionable results, tests performed during screening may be repeated before randomization to confirm eligibility. 2. Participants who have donated over 450 mL of blood or blood products or had significant blood loss within three months prior to screening. 3. Heavy smokers (those who smoke greater than or equal to 5 or more cigarettes a day within three months prior to screening).

Design outcomes

Primary

MeasureTime frameDescription
Number of Participants With Adverse Events (AEs)Up to 4 days for SAD, up to 3 days after the last dose of study drug for MADAn adverse event (AE) was defined as any untoward medical occurrence in a participant who was administered a pharmaceutical product (including investigational drug) during the course of a clinical investigation. An AE could therefore be any unfavorable and unintended sign (including abnormal laboratory findings), symptom, or disease that was temporally associated with the use of the investigational product, regardless of whether it was considered to be related to the investigational product or not.

Secondary
