The Safety, Tolerability, and Pharmacokinetics of TPN171H Tablets in Patients With Pulmonary Arterial Hypertension

Pulmonary Arterial Hypertension Clinical Trial

Official title:
Phase Ib Clinical Study on the Safety, Tolerability, and Pharmacokinetics of TPN171H Tablets in the Treatment of Pulmonary Arterial Hypertension (PAH) Patients

Clinical Trial Summary

Exploring the safety, tolerability, and pharmacokinetic (PK) characteristics of oral TPN171H tablets in patients with Pulmonary Arterial Hypertension under continuous multiple administration conditions, providing a basis for determining the administration plan and recommended dosage in phase II clinical study.

Clinical Trial Description

This study was divided into screening period, treatment period and medication follow-up period, and the treatment period included 3 cycles. First cycle: subjects receiving the test drug 2.5mg QD for 2 consecutive weeks, PK blood collection on Day 1 and Day 7, and the subjects discharged and returned to the hospital on Day 14 for medication monitoring blood collection, safety examination and efficacy assessment. Second cycle: up to 14 weeks; the second cycle is divided into monitoring and observation cycles; subjects who complete the first cycle and examinations enter the second cycle, with a 14 day monitoring period and 12 week observation period, with the second cycle dose of 5 mg QD, subjects received PK sampling on Day 7. Third cycle:The third cycle lasts for 8 days, subjects receive 10mg QD for 8 days; subjects received PK sampling on Day 7; subjects who completed an 8-day safety observation period on Day 8 without abnormal safety tests may be discharged. After discharge into the medication follow-up period. Medication follow-up period: up to 2 years; subjects entering the follow-up period will continue to take the dose of the last treatment period, return to hospital once every 12 weeks for safety examination and efficacy assessment until the subject intolerance or withdrawal from the study or expiration of 2 years (whichever occurs first). ;
