There are 3 clinical trials
This is a single-center, randomized, double-blind, placebo-controlled, sequential group study. The primary objective of this study is to assess the tolerability and safety of single doses of ME1100 inhalation solution (orally inhaled arbekacin). The secondary objective is to determine the systemic exposure to, and urinary elimination of, ME1100.

This is a single-center, open-label, single-dose study. The primary objective is to determine Epithelial Lining Fluid (ELF) levels of ME1100 after a single orally inhaled dose. The secondary objectives are to determine systemic exposure to inhaled ME1100 and to assess tolerability and safety of a single dose of ME1100 inhalation solution.
