Drug-Drug Interactions of JMKX003142 in Healthy Participants

Starting soon · Phase 1

Conditions studied: ADPKD (Autosomal Dominant Polycystic Kidney Disease)

In brief

This is a single-center, non-randomized, open-label, self-controlled, Phase I clinical trial to evaluate the drug-drug interactions (DDI) of JMKX003142 tablets in healthy adult participants. The study consists of five cohorts (Cohorts 1, 2, 3, 4, and 5). A total of 24 participants are planned enrollment in each of Cohorts 1, 2, 3, and 5, while 16 participants are planned for Cohort 4.

• Healthy Chinese male or female subjects, as determined by medical history and physical examination. At the time of signing the Informed Consent Form (ICF), aged 18-45 years (inclusive) ; body weight ≥ 50 kg for males or ≥ 45 kg for females; and Body Mass Index (BMI) within the range of 19.0-26.0 kg/m² (inclusive).
• Participants were considered healthy by the Investigator based on medical history, baseline physical examination, clinical laboratory assessments, and 12-lead ECG, with all results judged as normal or not clinically significant.
• Participants of childbearing potential who agree to use effective contraception and have no plans for conception, cryopreservation, or donation of gametes from ICF signature through 3 months after the last dose.

You may not qualify if…

• Known or suspected hypersensitivity to JMKX003142 (active ingredient or excipients), or a history of hypersensitivity to more than two drugs, foods, or other substances.
• History or presence of clinically significant diseases in any of the following systems (including but not limited to): cardiovascular, respiratory, gastrointestinal, hematologic, genitourinary, endocrine/metabolic, nervous, psychiatric, musculoskeletal, dermatologic, lymphatic, immune, or sensory organs; or current active local or systemic infection.
• Any condition increasing the risk of bleeding, such as acute gastritis, active ulcer with hemorrhage, clinically significant thrombocytopenia or anemia, active pathological bleeding, or a history of intracranial hemorrhage.
• Vital signs meet any of the following criteria at screening: systolic blood pressure ≥ 140 mmHg or < 90 mmHg; diastolic blood pressure ≥ 90 mmHg or < 50 mmHg; pulse rate > 100 bpm or < 50 bpm; or tympanic temperature ≥ 37.5°C or < 35°C.
• Subjects with a history of QTc interval prolongation or a family history of Long QT Syndrome; or those with clinically significant abnormal ECG findings as determined by the Investigator during screening; or a QTcF ≥ 450 ms; or a QRS interval > 120 ms.
• Positive for Hepatitis B surface antigen (HBsAg), Hepatitis C virus (HCV) antibody, Human Immunodeficiency Virus (HIV) antibody, or syphilis serology.
• Treatment with therapeutic biological products within 3 months (or 5 half-lives, whichever is longer) prior to dosing, or other prescription/non-prescription medications (including vaccines, Traditional Chinese Medicine [TCM], dietary supplements, and health products) within 1 month (or 5 half-lives, whichever is longer).
• Use of any investigational drug within 3 months prior to screening, or current participation in another clinical trial.
• Major surgery (e.g., requiring general or epidural anesthesia) within 3 months prior to screening, or planned surgical intervention during the study.

• Smoking ≥5 cigarettes per day within 3 months prior to screening, or inability to commit to abstaining from tobacco products during the study, or a positive nicotine screening result.
• History of heavy alcohol consumption (>14 units per week; 1 unit ≈ 10 mL alcohol, equivalent to approx. 285 mL beer [3.5%], 25 mL spirits [40%], or 100 mL wine [10%]), inability to abstain from alcohol after screening, or a positive alcohol breath test.
