E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The main aim of the trial is double: (1) Evaluate the clinical effectiveness of the 3 short-course antibiotic regimens (3 g of fosfomycin once daily for two-days; three-day pivmecillinam 400 mg. t.i.d.; five-day nitrofurantoin 100 mg t.i.d.) and the single 3 g dose of fosfomycin in uncomplicated LUTIs in adult women at day 7; and (2) Assess the bacteriological eradication in the four medication arms, measured at day 14. |
El objetivo principal es doble: (1) Evaluar la efectividad clínica de 3 pautas antibióticas cortas (3 g de fosfomicina trometamol una vez al día, 2 días; pivmecillinam 200 mg. 2 comp t.i.d., 3 días; nitrofurantoína 50 mg 2 comp. t.i.d., 5 días y monodosis de fosfomicina trometamol 3 g en el día 7; y (2) Evaluar la erradicación bacteriológica en el día 14 en cada una de las estrategias del ensayo clínico. |
|
E.2.2 | Secondary objectives of the trial |
To evaluate in the four medication arms: - Time to clinical recovery. - Bacteriological efficacy at day 28. - Proportion of patients presenting a relapse of symptoms within the first four weeks after inclusion in the study and timing of relapse of symptoms and/or bacteriuria. - Proportion of patients developing complications (i.e. pyelonephritis and/or urosepsis) within the first 4 weeks. - Treatment Adherence - Proportion of patients who have taken another antibiotic during the study period. - Satisfaction with care. - Change in the quality of life. - Mapping of uropathogens causing uncomplicated LUTIs and resistance rates to the antibiotics evaluated in the project. - Predictive value of the different clinical criteria collected with microbiologically-confirmed LUTI. - Cost-effectiveness of each of the treatment arms (cost of the drug, consumption of resources and indirect costs).
