简要总结
This is a phase 1, placebo-controlled, blinded, randomized, dose escalation study of PBI-0451 in healthy subjects. PBI-0451 is a new chemical entity and inhibitor of the main protease of coronaviruses, including the SARS-CoV-2 that causes COVID-19 disease. The study is designed to evaluate the safety, tolerability and pharmacokinetics of PBI-0451 after single and multiple ascending doses and also to explore drug-drug interaction potential of PBI-0451.
详细描述
Combined Three part, double blind, (sponsor open) study. Part 1: Single ascending dose study. Part 2: Multiple ascending dose study. Part 3: Drug-drug interaction study.

结局指标
主要结局
Number of subjects with treatment emergent adverse events (TEAEs) in Single Ascending Dose (SAD) compared to placebo
时间窗: Day 1- Day 14 (From start of study medication till 14 days of last administration of study drug)
An adverse event is any untoward medical occurrence in patient or clinical study participant temporarily associated with the use of study intervention, whether or not considered related to the study intervention. A serious adverse event (SAE) is defined as any untoward medical occurrence at any dose that results in death; is life threatening; requires inpatient hospitalization or prolongation of existing hospitalization; results in persistent disability/incapacity; results in congenital anomaly/birth defect. AEs include both SAEs and AEs. TAEs are AEs that occur following the start of treatment or AEs increasing in severity during treatment.
Number of subjects with treatment emergent adverse events (TEAEs) in Multiple Ascending Dose (MAD) compared to placebo
时间窗: Day 1-Day 11, and Follow up (after 14 days)
