A Randomized Double-blind Placebo-controlled First-in-man Single-dose and Multiple Dose Study to Evaluate the Safety, Tolerability and Efficacy of a Recombinant Chimeric Bacteriophage Endolysin HY-133 With an Extended Phase to Evaluate Effects of the Nasal Microbiome

2023-507737-17-00

In this clinical trial we will test a new approach for decolonization of S. aureus. As innovative product HY-133 a recombinant chimeric bacteriophage endolysin will be sprayed in both nostrils of healthy subjects once or five times in one day. To avoid possible bias the subjects will be randomized 3:2 verum vs placebo, moreover the subject as well as the investigator will be blinded to the group assigned.
