June 11, 2009 updated by: Rabin Medical Center

Efficacy & Tolerability of Progesterone Vaginal Tablets (Endometrin®) in Menopausal Women Treated by Estrogen Replacement Therapy - Phase II Comparative Study

The objective of the study is to confirm that the efficacy of vaginal progesterone is at least as good as oral progesterone in order to protect the endometrium of uncontrolled proliferation and prevent endometrial cancer.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Time Frame
Comparing the proportion of women with endometrial thickness not exceeding 8mm and change not exceeding 3mm between the two groups.
Time Frame: 1 year
1 year

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Time Frame
Comparison of the proportion of bleeding pattern between the two groups.
Time Frame: 1 year
1 year
To demonstrate that vaginal progesterone tablets decrease systemic progesterone adverse reactions using a questionnaire.
Time Frame: 1 year
1 year
