First-in-man Single-dose and Multiple Dose Study to Evaluate the Safety, Tolerability and Efficacy ofHY-133

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

Sponsor

University Hospital Tuebingen

Enrollment

52 participants

Start Date

Jul 10, 2024

Study Type

INTERVENTIONAL

Conditions

Staphylococcus Aureus

Summary

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.
