Trial Outcomes & Findings for E4 FREEDOM (Female Response Concerning Efficacy and Safety of Estetrol/Drospirenone as Oral Contraceptive in a Multicentric Study) - EU/Russia Study (NCT NCT02817828)

NCT ID: NCT02817828

Last Updated: 2019-10-04

Results Overview

On-treatment pregnancies are defined as pregnancies with an estimated date of conception within the in-treatment period i.e. Day 1 to 2 days after the last intake of investigational product (whether active or inactive tablet). The Pearl Index, defined as the number of pregnancies per 100 women-years of treatment was calculated as: Pearl Index = (1300\*number of on-treatment pregnancies)/number of women 28-day equivalent cycles of treatment.Only at-risk cycles were included in the denominator of the Pearl Index calculation. At-risk-cycles were defined as cycles in which no other methods of birth control (including condoms) were used by the subject as confirmed in the subject diary and during which the subject confirmed that sexual intercourse had occurred.

Participant Flow

A total of 1,577 participants aged 18-50 years were enrolled. Of those, 1,553 started the study treatment. Twenty-four participants did not start the treatment for the following reasons: consent withdrawn (8), unspecified reason (5), protocol deviation (3), pregnancy (4), lost to follow-up (3), and adverse event not related to bleeding (1).

SECONDARY outcome

Timeframe: Baseline and Cycle 13 (1 cycle = 28 days)

Population: Participants aged 18 to 50 years, inclusive, at screening with baseline and end of treatment Q-LES-Q-SF results.

The Q-LES-Q-SF is a self-report measure designed to assess the degree of enjoyment and satisfaction in daily functioning. Participants were asked to rate 16 different items on a 5-point scale where score 1 = very poor and score 5 = very good. A raw total score is calculated by summing the first 14 items and ranges from 14 to 70 with a higher scores indicating higher life enjoyment and satisfaction. The raw total score is then transformed into a percentage maximum score using the following formula: (raw total score-minimum score)/(maximum possible raw score-minimum score). In addition, the last two items (15 and 16) are two global items that are scored individually. These items rate "satisfaction with medicine" and "overall life satisfaction over the past week".

Timeframe: Baseline and Cycle 13 (1 cycle = 28 days)

Population: Participants aged 18 to 50 years, inclusive, at screening with both baseline and end of treatment MDQ results.

The MDQ is a standard method for measuring cyclical perimenstrual symptoms. The participants rated common symptoms and feelings associated with menstruation using the following scale: 0 (no experience of symptom), 1 (present, mild), 2 (present, moderate), 3 (present, strong),and 4 (present, severe) observed during pre-menstrual (4 days before menstruation), menstrual (most recent flow) and intermenstrual (remainder of the cycle) phases. Reported values are values at Cycle 13 minus values at Baseline. An overall positive change from baseline represents an increase in symptom or feeling severity.
