A prospective multi-centre PK study was conducted in China between 2016 and 2019. Population PK models were developed using nonlinear mixed-effect analyses based on the blood samples collected by rich sampling. The probability of target attainment (PTA) analysis was estimated using the Monte Carlo simulation.<
