Material Balance of [14C]Zorifertinib in Healthy Adult Male Participants in China

Recruiting now · Phase 1

Conditions studied: EGFR Mutant Advanced Non-small Cell Lung Cancer, Central Nervous System (CNS) Metastases

In brief

This is a single-center, single-dose, open-label, Phase I study to evaluate the mass balance, biotransformation, pharmacokinetic characteristics, excretion pathways, and safety of a single oral 200 mg/5 µCi dose of \[14C\]Zorifertinib in healthy Chinese adult male participants. The study includes a screening period (Day -14 to Day -1) and a dosing and observation period (Day 1 to Day 14). Blood, urine, and feces samples will be collected to measure radioactivity, drug concentrations, and metabolites. Safety will be assessed by adverse events, vital signs, laboratory tests, 12-lead ECG, and ophthalmic examinations. The target total radioactivity recovery is ≥90% of the administered dose.

You may not qualify if…

• Ancillary Examinations:
• Abnormal findings from comprehensive physical examination, vital signs, laboratory tests (hematology, blood biochemistry, coagulation function, urinalysis, routine stool + occult blood, thyroid function), 12-lead ECG, chest X-ray (posteroanterior view), abdominal ultrasound, digital rectal examination, etc., that are judged by the investigator as clinically significant.
• Resting corrected QT interval (Fridericia correction, QTcF = QT/RR1/3) obtained from 12-lead ECG >450 ms in males, or other abnormalities judged by the investigator as clinically significant.
• Positive result for any of the following: hepatitis B surface antigen or hepatitis B e antigen, hepatitis C virus antibody, Treponema pallidum antibody, or human immunodeficiency virus antigen/antibody combination test (HIV-Ag/Ab).
• Abnormal findings from ophthalmic examination (slit lamp, intraocular pressure, fundus photography) that are clinically significant.
• Medication History:
• Use of any drugs that inhibit or induce the drug-metabolizing enzyme CYP3A4 within 30 days prior to the screening period.
• Use of any prescription drugs, over-the-counter drugs, herbal medicines, or food supplements (e.g., vitamins, calcium supplements) within 14 days prior to the screening period.
• Medical and Surgical History:
• History of any clinically serious disease or condition that the investigator believes may affect the trial results, including but not limited to circulatory, respiratory, endocrine, nervous, digestive, urinary, hematologic, immune, psychiatric, or metabolic diseases;
• History of dysphagia or any condition that may affect drug absorption, e.g., gastrectomy, cholecystectomy, gastric bypass, duodenotomy, colectomy, inflammatory bowel disease;
• History of organic heart disease, heart failure, myocardial infarction, angina pectoris, arrhythmia, ventricular tachycardia, clinically symptomatic AV block, long QT syndrome, or family history of long QT syndrome (evidenced by genetic proof or sudden cardiac death of a close relative at a young age);
• Major surgery within 6 months prior to the screening period, or surgical incision not fully healed; Major surgery includes, but is not limited to, any procedure with significant bleeding risk, prolonged general anesthesia, incisional biopsy, or significant traumatic injury;
• Allergic constitution, e.g., known history of allergy to two or more substances; Or judged by the investigator as potentially allergic to the investigational drug;
• Hemorrhoids or perianal diseases with regular/ongoing hematochezia, irritable bowel syndrome, inflammatory bowel disease.
• Lifestyle Habits:
• Habitual constipation or diarrhea;
• Alcoholism or regular alcohol consumption within 6 months prior to screening, i.e., alcohol intake exceeding 14 units per week (1 unit = 360 mL beer, or 45 mL spirit with 40% alcohol, or 150 mL wine), or a breath alcohol test result ≥20 mg/dL at screening, or inability to abstain from alcohol during the trial period;
• Smoking >5 cigarettes per day or habitual use of nicotine-containing products within 3 months prior to screening, or inability to abstain during the trial period;
• Drug abuse or use of soft drugs (e.g., cannabis) within 3 months prior to screening, or use of hard drugs (e.g., amphetamines, phencyclidine) within 1 year prior to screening; Or positive urine screen for drugs of abuse during the screening period;
• Habitual consumption of grapefruit juice or excessive tea, coffee, and/or caffeinated beverages, and inability to abstain during the study period.
• Others:
• Participation in a radiolabeled drug trial within 1 year prior to screening, or participation in a 14C-labeled breath test within 3 months prior to screening;
• History of needle phobia or blood phobia, difficulty with blood collection, or inability to tolerate venous puncture;
