Clinical Study Assessing the Safety, Tolerability, and Pharmacokinetics of Intravenous AZD5099 in Healthy Subjects

A Phase I, Single-center, Double-blind, Randomized, Placebo-controlled, Parallel-group Study to Assess the Safety, Tolerability and Pharmacokinetics in Intravenous AZD5099 After Single Ascending Doses in Healthy Male and Female Subjects

The purpose of this study is to evaluate the safety, tolerability and pharmacokinetics of the drug AZD5099 after intravenous administration of single doses in healthy volunteers. The results from this study will form the basis for decisions regarding the future development of AZD5099 as a novel antibiotic for the treatment of serious infections in humans.
