This is the first time finafloxacin was administered to humans intravenously. The principal aim of this study was to obtain safety and tolerability data when finafloxacin was administered intravenously as single and multiple doses to healthy subjects.

Clinical Trial Outcome Measures
- Time Frame: 1 to 7 days
- The primary objective was to evaluate the safety and tolerability of single and multiple intravenous (IV) doses of finafloxacin in healthy subjects. The safety evaluation includes the descriptive display and analysis of adverse events after single and multiple doses for 7 days of intravenously administered finafloxacin. The frequency of adverse events is evaluated for all casualties and for drug related adverse events. Comparisons between the placebo and verum groups are provided in descriptive manner. In addition the evaluation of clinical laboratory data, vital signs, electrocardiography data, physical examination, local tolerability is provided.
- Pharmacokinetic parameters of finafloxacin in plasma and urine samples from healthy subjects using non compartmental procedures
- Time Frame: 1 to 7 days
- The pharmacokinetic parameters determined for single dose are: AUC, Cmax, tlast, t½, CL, VZ, VSS, amount of drug excreted in urine, fraction of dose excreted in urine, renal clearance. The pharmacokinetic parameters determined for multiple dose are: AUC, Cmax, tmax, t½, observed accumulation ratio, predicted accumulation ratio, linearity ratio, CL, VZ, VSS, amount of drug excreted in urine, fraction of dose excreted in urine, renal clearance. In addition, dose and body weight normalised values (norm) for AUC 0-τ, AUC0- tlast, AUC and Cmax were determined by dividing the original pharmacokinetic parameter by dose per kg body weight. Body weight normalised values [norm] for CL, VZ and CLR were calculated by dividing the original pharmacokinetic parameter by body weight.
Participating in This Clinical Trial

- Female subjects must be of non-childbearing potential, and are defined as follows: Female subjects 50 years of age or less must be surgically sterile or post-menopausal (defined as at least two years post cessation of menses and/or follicular stimulating hormone >40 mIU/mL and serum oestradiol <110 pmol/L).
Female subjects of more than 51 years of age must be surgically sterile or post-menopausal (defined by a value of follicular stimulating hormone >40 mIU/mL and no spontaneous menstruation for at least one year before the first dose).

- Subjects who have received any prescribed systemic or topical medication within 14 days (or corticosteroids within 4 weeks) of the first dose administration (for female subjects, stable hormone replacement therapy is acceptable) unless in the opinion of the Investigator the medication will not interfere with the study procedures or compromise safety.
- Subjects who have used any non-prescribed systemic or topical medication (including herbal remedies) within 7 days of the first dose administration (with the exception of vitamin/mineral supplements) unless in the opinion of the Investigator the medication will not interfere with the study procedures or compromise safety.
- Subjects who have received any medications, including St John's Wort, known to chronically alter drug absorption or elimination processes within 30 days of the first dose administration unless in the opinion of the Investigator the medication will not interfere with the study procedures or compromise safety.
- Subjects who are still participating in a clinical study (e.g. attending follow-up visits) or who have participated in a clinical study involving administration of an investigational drug in the past 3 months.
- Subjects who have donated any blood, plasma or platelets in the 3 months prior to randomisation or who have made donations on more than two occasions within the 12 months preceding the first dose administration.
