简要总结
This is a randomised, double-blind, 3-part study designed to investigate the safety and tolerability of ATM-AVI. The study aims to characterise the pharmacokinetics of ATM-AVI, when both drugs are administered alone (ATM or AVI) and in combination (ATM-AVI), following single administration, and following multiple administrations of ATM-AVI in healthy male and female (females of nonchildbearing potential) volunteers both young and elderly.
