Exclusion criteria

Exclusion criteria: 1. Electrocardiogram (ECG) 12-leads (supine position): clinically significant abnormalities 2. Physical findings: clinically significant abnormal physical findings which could interfere with the objectives of the study 3. Laboratory analyses: clinically significant abnormal laboratory values indicative of physical illness 4. Allergy: ascertained or presumptive hypersensitivity to the active principle and/or formulations' ingredients; history of anaphylaxis to drugs or allergic reactions in general, which the investigator considers may affect the outcome of the study 5. Diseases: significant history of renal, hepatic, gastrointestinal, cardiovascular, respiratory, genitourinary, skin, haematological, endocrine or neurological diseases that may interfere with the aim of the study 6. Medications: medications, including over the counter (OTC) medications and herbal remedies for 2 weeks before the screening visit 7. Investigative drug studies: participation in the evaluation of any investigational product for 3 months before this study.

Design outcomes

Primary

MeasureTime frame
Fosfomycin concentrations and pharmacokinetics evaluated in plasma and urine using a fully validated liquid chromatography with tandem mass spectrometry (LC-MS-MS) method after one dose (Day 1) and two consecutive doses (Day 4) of the investigational medicinal product

Secondary

MeasureTime frame
1. Fosfomycin concentrations evaluated in prostate and seminal vesicles using a fully validated liquid chromatography with tandem mass spectrometry (LC-MS-MS) method after one dose (Day 1) and two consecutive doses (Day 4) of the investigational medicinal product 2. Safety and tolerability of the treatment evaluated by collecting the adverse events during the whole study and measuring vital signs (blood pressure and heart rate) at screening, on Days 1-2 and Days 4-5 and at the final visit. Safety and tolerability of the treatment are also evaluated by measuring the laboratory parameters, performing physical examinations including body weight and registering the ECG at screening and the final visit.
