Healthy volunteers needed to test drug interactions for cancer drug candidate

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Any drug known to be an inhibitor or inducer of CYP3A4 enzymes or a sensitive substrate (Appendix 4), any drug known to be a P-gp inhibitor or substrate (Appendix 5), any drug known to be a BCRP inhibitor or substrate (Appendix 6), or any drug known to cause a risk of torsades de pointes (TdP) (Appendix 7) within 4 weeks; 10. Vaccination within 3 months or planned during this trial; 11. Subjects with a history of bleeding and needle phobia, unable to tolerate intravenous indwelling needle injection; 12. Subjects with neurological/psychiatric, respiratory, cardiovascular, digestive tract, blood and lymphatic system, endocrine, musculoskeletal disorders, liver and kidney dysfunction, or any other diseases and physiological conditions that may affect the study results at screening; 13. Screening or baseline 12-lead ECG with QTcF interval ≥ 450 ms (males), QTcF interval ≥ 460 ms (females); or ECG abnormal and considered abnormal and clinically significant by the investigator; 14. Laboratory test results during screening period or baseline period meet the following abnormal range requirements and are considered abnormal and clinically significant by the investigator: 1. Abnormal liver function: alanine aminotransferase (ALT) or aspartate aminotransferase (AST)≥ULN; 2. Abnormal coagulation function: activated partial thromboplastin time (APTT) or international normalized ratio (INR) ≥ULN; 3. Abnormal thyroid function: Free triiodothyronine (FT3) or free thyroxine (FT4) or thyroid stimulating hormone (TSH) higher than ULN; 15. Subjects with hepatitis B surface antigen quantitative determination positive, hepatitis C antibody quantitative determination positive, human immunodeficiency virus antigen antibody determination positive or treponema pallidum antibody determination positive at screening period or baseline period; 16. Have special requirements for diet and fail to comply with the diet and corresponding regulations provided by the clinical trial institution; 17.
