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
The primary efficacy endpoint will be the changes in FSH and LH secretion induced by daily administration of the drug for 21 consecutive days during the 28 days of participation in the trial.
Time Frame: 1, 2, 4, 7, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 24 and 28 days
1, 2, 4, 7, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 24 and 28 days

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
Safety of drugs: type, frequency and intensity of adverse events between groups during the 28 day trial. Exploratory investigation of the pharmacokinetics of the drug administered through the dosage of hormones in serum LNG and EE2 for 28 days.
Time Frame: PK: 1 (0, 1, 2, 3, 4, 5, 6, 12 e 18 hours after administration), 2, 7, 14, 21 and 28 days
PK: 1 (0, 1, 2, 3, 4, 5, 6, 12 e 18 hours after administration), 2, 7, 14, 21 and 28 days
