Study summary

The purpose of this study is to study the safety of single doses and multiple doses of Finafloxacin hydrochloride in healthy volunteers. The level of Finafloxacin hydrochloride will be measured in the subjects blood and urine. One part of the study will assess if Finafloxacin hydrochloride eradicates Helicobacter pylori, a stomach bacteria. Another part of the study will assess the activity of the drug in urine.

Read the detailed description

New antibiotics are needed due to the increasing resistance of bacteria to existing antibiotics. Helicobacter pylori (H. pylori) is a bacteria of the stomach and has been shown to cause peptic ulcers and is implicated in gastric cancer. Up to 40% of the population has H. pylori. Current treatments used to eradicate H. pylori are a combination of a number of drugs including antibiotics and drugs which reduce the acid in the stomach. These treatments are complicated and some H. pylori is resistant to the antibiotics used.

This study is the first use of Finafloxacin hydrochloride in man and will examine its safety and make a preliminary study of its effectiveness as a single agent in eradicating H. pylori. The urine of subjects will also be used to test its effectiveness in killing the bacteria which cause urinary tract infections.

What researchers measure

Primary outcomes

  1. To evaluate the safety and tolerability of single and multiple oral doses of Finafloxacin HCl by assessing adverse events, physical examinations, clinical chemistry examination, hematology, ECG and urinalysis.

    Time frame: 7 days

Secondary outcomes

  1. To determine the pharmacokinetic profile of single and multiple oral doses of Finafloxacin HCl in healthy subjects

    Time frame: 7 days

  2. To determine the bactericidal activity of urine obtained from healthy subjects after administration of Finafloxacin HCl

    Time frame: 7 days

  3. To explore the activity of multiple oral doses of Finafloxacin HCl against Helicobacter pylori using the effect on the urease breath test in healthy carriers as a model

    Time frame: 7 days
