E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
to evaluate the protective effect of progesterone on the endometrium of post-menopausal women under HRT, assessed by measurement of endometrial thickness, upon administration of two dosing schemes (continuous sequential and combined continuous) of progesterone 25 mg solution administered by oral route, compared to an oral progesterone 200 mg capsule (Prometrium). |
Valutare l’effetto protettivo del progesterone sull’endometrio di donne in post menopausa sottoposte a terapia ormonale sostitutiva con estrogeno. La valutazione viene fatta per mezzo della misurazione dello spessore endometriale in seguito a due differenti schemi di assunzione (continuo sequenziale e combinato continuo) del progesterone 25 mg soluzione somministrato per via orale comparato a progesterone orale 200 mg in capsule (Prometrium). |
|
E.2.2 | Secondary objectives of the trial |
Histological assessment of the endometrium; Incidence of withdrawal bleeding and/or irregular bleeding; Safety evaluation (adverse events).
|
Valutazione istologica dell'endometrio; incidenza di sanguinamento vaginale regolare o irregolare; valutazione della sicurezza (eventi avversi). |
|
E.2.3 | Trial contains a sub-study | No |
