- Brief Summary
This is a single center, open label, drug-drug interaction, Phase 1 study of TNP-2198 in approximately 32 healthy participants, includes 2 cohorts (16 participants per cohort): Midazolam cohort and Clarithromycin cohort. Midazolam cohort will evaluate the effect of multiple oral doses of TNP-2198 capsules on the pharmacokinetics (PK) parameters of a single oral dose of midazolam, a cytochrome P-450 (CYP) 3A sensitive substrate, in healthy participants; Clarithromycin cohort will evaluate the effect of multiple oral doses of clarithromycin tablets, a strong CYP3A and P-gp inhibitor, on the PK parameters of multiple oral doses of TNP-2198 in healthy participants.
- Detailed Description
Midazolam cohort: Midazolam oral solution will be administered orally at a dose of 2 mg once a day within 0.5 hours after breakfast on Day 1, and administered following TNP-2198 capsules within 0.5 hours after breakfast on Day 10. TNP 2198 capsules will be administered orally at a dose of 400 mg twice a day, within 0.5 hours after breakfast and dinner, from Day 3 to Day 11. PK blood sampling and safety tests were performed at specified time points.
Clarithromycin cohort: TNP-2198 capsules will be administered orally at a dose of 400 mg twice a day, within 0.5 hours after breakfast and dinner, from Day 1 to Day 7, and within 0.5 hours after breakfast on Day 8. Clarithromycin tablets will be administered at a dose of 0.5 g twice a day, within 0.5 hours after breakfast and dinner, from Day 16 to Day 25. TNP-2198 capsules will be administered within 0.5 hours after breakfast and dinner, followed by clarithromycin tablets, from Day 16 to Day 22. TNP-2198 capsules will be administrated within 0.5 hours after breakfast, followed by clarithromycin tablets on Day 23. PK blood sample collection and safety tests were performed at specified time points.

- Secondary Outcome Measures
Name Time Method Midazolam cohort: Percentage of Participants With Adverse Events (AEs) Day 1 to Day 12 An Adverse Event (AE) is any untoward medical occurrence in a participant administered a pharmaceutical product and which does not necessarily have to have a causal relationship with the treatment. An Adverse Event can therefore be any unfavorable and unintended sign (including abnormal laboratory values or abnormal clinical test results), symptom, or disease temporally associated with the use of a pharmaceutical product, whether or not considered related to the pharmaceutical product. Preexisting conditions which worsen during a study are also considered as Adverse Events
Clarithromycin cohort:Percentage of Participants With Adverse Events (AEs) Day 1 to Day 26 An Adverse Event (AE) is any untoward medical occurrence in a participant administered a pharmaceutical product and which does not necessarily have to have a causal relationship with the treatment.
