Trial Outcomes & Findings for Effectiveness of Orally Dosed Emergency Contraception in Obese Women - UPA (NCT NCT02859337)

NCT ID: NCT02859337

Last Updated: 2024-02-06

Results Overview

Follicular rupture (yes/no) beyond 5 days from EC dosing by ultrasound in participants with a BMI \>/=30 kg/m2. The comparison is between menstrual cycles where 30 versus 60 mg of UPA was taken. Follicular rupture is defined as the disappearance of or \>50% reduction in size of the leading follicle. The day of EC dosing is defined as day zero.

PRIMARY outcome

Timeframe: 1 menstrual cycle, assessed up to 38 days

Population: The total analyzed number is the menstrual cycle of the participant with a BMI \>/=30kg/m2 when dosed with ECx1 or ECx2 who experienced a delay in follicular rupture beyond 5 days after dosing EC.

Follicular rupture (yes/no) beyond 5 days from EC dosing by ultrasound in participants with a BMI \>/=30 kg/m2. The comparison is between menstrual cycles where 30 versus 60 mg of UPA was taken. Follicular rupture is defined as the disappearance of or \>50% reduction in size of the leading follicle. The day of EC dosing is defined as day zero.
