E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To evaluate efficacy (clinical benefit) of two doses of ZK PRA (25 mg and 100 mg) when administered once daily p.o. |
Valutare l'efficacia (in termini di beneficio clinico) di ZK PRA somministrato a due dosaggi (25 versus 100 mg, una volta al giorno per 6 mesi) come trattamento di seconda linea ormonale in pazienti post-menopausa con carcinoma metastatico della mammella e positivita' ai recettori ormonali. |
|
E.2.2 | Secondary objectives of the trial |
To evaluate: safety and tolerability; pharmacokinetics of ZK PRA; the effect of ZK PRA on quality of life (QoL); to perform exploratory analysis of biomarkers. |
Valutare: sicurezza e tollerabilita' dei trattamenti sopra indicati con ZK PRA; farmacocinetica di ZK PRA; effetto di ZK PRA sulla qualita' di vita; analisi esplorativa di marcatori molecolari non genetici |
