Abstract

Zoliflodacin is a novel spiropyrimidinetrione with activity against bacterial type II topoisomerases that inhibits DNA biosynthesis and results in accumulation of double-strand cleavages in bacteria. We report results from two phase 1 studies that investigated the safety, tolerability, and pharmacokinetics (PK) of zoliflodacin and absorption, distribution, metabolism, and excretion (ADME) after single doses in healthy volunteers.
