PHASE1

Pharmacokinetic Study of Sudapyridine（WX-081）in Healthy Chinese Subjects

Sponsor: Shanghai Jiatan Pharmatech Co., Ltd

View on ClinicalTrials.gov

Summary

This single-center, open-label, non-randomized study aims to evaluate the pharmacokinetics, mass balance, and metabolic pathways of WX-081 (Sudapyridine) following a single oral dose of \[U-14C\] WX-081 in healthy Chinese male volunteers. A total of 6-10 subjects will be enrolled to obtain complete samples and data from at least six participants. Biological samples, including blood, plasma, urine, and feces, will be collected over a specified time period. The study will assess pharmacokinetic parameters, excretion pathways, and identify major metabolites contributing to over 10% of plasma exposure.

[U-14C] WX-081

A single oral dose of approximately 450 mg (100 μCi) of \[U-14C\] WX-081 will be administered to healthy male volunteers. The study will involve pharmacokinetic assessments, including metabolism, mass balance, and excretion pathways, through the collection of biological samples such as blood, plasma, urine, and feces.

Inclusion Criteria: * Healthy adult males. Age: 18-45 years (inclusive). Body weight: BMI between 19.0 and 26.0 kg/m² (inclusive), with body weight not less than 50.0 kg. Voluntarily signed the informed consent form. Able to communicate effectively with investigators and comply with the study protocol. Exclusion Criteria: * Clinically significant abnormalities identified through physical examination, vital signs, laboratory tests (e.g., blood count, biochemistry, troponin, coagulation function, urinalysis, fecal occult blood), thyroid function, 12-lead ECG, chest X-ray, rectal examination, or abdominal ultrasound (liver, gallbladder, pancreas, spleen, kidney). Prolonged corrected QT interval (QTcF) \> 450 msec on 12-lead ECG. Positive results for hepatitis B surface antigen (HBsAg or HBeAg), hepatitis C antibody (HCV-Ab), syphilis antibody, or HIV antigen/antibody (HIV-Ag/Ab). Use of drugs that inhibit or induce hepatic enzymes or transporters within 30 days prior to screening. Use of prescription or over-the-counter medications, herbal remedies, or dietary supplements (e.g., vitamins, calcium) within 14 days prior to screening. Any clinically significant disease or condition that may affect study results, including but not limited to cardiovascular, respiratory, endocrine, neurological, gastrointestinal, urinary, hematological, immune, psychiatric, or metabolic disorders. Conditions that could affect drug absorption, such as a history of gastric surgery (e.g., gastrectomy, gastric bypass), gallbladder removal, or inflammatory bowel disease. History of organic heart disease, heart failure, myocardial infarction, angina, unexplained arrhythmia, ventricular tachycardia, atrioventricular block, long QT syndrome, or family history of sudden cardiac death due to cardiac reasons. Major surgery within 6 months prior to screening or incomplete surgical wound healing. Known hypersensitivity or allergy to two or more substances, or potential allergy to the investigational drug or its excipients (e.g., lactose, low-substituted hydroxypropyl cellulose, sodium lauryl sulfate, silicon dioxide, magnesium stearate). Hemorrhoids or perianal conditions with regular or current rectal bleeding.
