NCT03798197

Brief Summary

Assessment of the effect of a high fat meal on the quantity in blood of a female sex hormone called estetrol (E4). The study also aims at determining how subject tolerate the study drug and how safe it is for them.

  • Number of subjects with adverse events as measure of safety and tolerability

    From Day 28 prior screening to end of study (Day 4 of Period 2)

Study Arms (2)

30 mg estetrol (E4) without food (fasted)

ACTIVE COMPARATOR

Treatment A (reference): One 30 mg E4 tablet administered orally following an overnight fast of at least 10 hours.

Drug: 30 mg estetrol (E4)

30 mg estetrol (E4) with food (fed)

EXPERIMENTAL

Treatment B (test): One 30 mg E4 tablet administered orally 30 min after the start of an FDA prescribed high-fat breakfast preceded by at least a 10 hours overnight fast.

Drug: 30 mg estetrol (E4)

Interventions

All subjects received both Treatment A and Treatment B either at the first treatment period (Period 1) or at the second treatment period (Period 2). Approximately half of the subjects was randomized to receive either Treatment A followed by Treatment B (sequence AB), or Treatment B followed by Treatment A (sequence BA).
