Condition(s) targeted: Contraception

Intervention: Moxifloxacin (Drug); NOMAC-E2 (Org 10486-0 + Org 2317) (Drug); Moxifloxacin placebo (Drug); NOMAC-E2 placebo (Drug)

Phase: Phase 1

Status: Completed

Sponsored by: Merck Sharp & Dohme Corp.


The trial is a single-center randomized, double-blind, double-dummy, placebo and positive controlled, parallel group clinical trial.

This trial investigated whether NOMAC-E2 (Org 10486 - 0 + Org 2317), a new combined hormonal

contraceptive, has potential to delay cardiac repolarization. The primary measure of cardiac repolarization in this trial is the Fridericia corrected QT interval (QTcF). QTcF represents the duration of ventricular depolarization and subsequent repolarization. A delay in cardiac repolarization creates an electrophysiological environment that favors the development of cardiac arrhythmias, most clearly torsade de pointes (TdP), but possibly other ventricular tachyarrhythmias. The primary aim of this study is to investigate, if the administration of a therapeutic (2. 5/1. 5 mg) or supra-therapeutic (higher than required for treatment: 12. 5/7. 5 mg) dose of NOMAC-E2 administered over a period of 14 days will prolong the mean QTcF interval to values above the accepted threshold of regulatory concern. In addition, a single dose of moxifloxacin will be administered in order to prove that sensitivity of the applied assay is sufficient to detect the prolongation of the QTcF-interval. Secondary aims of this study are to evaluate the relation between concentrations of NOMAC (therapeutic and supra-therapeutic) after steady state has been reached in the subject's body, the time matched change in Estradiol E1 and E2 in relation to baseline and the QTcF intervals after multiple dose administration of NOMAC-E2. Finally, the safety and tolerability of different treatments are investigated. A total of 189 subjects will participate in this trial. The entire study duration is about 9 weeks with a 4-week screening period, 14-day treatment period and a follow-up period of about 3 weeks.

Clinical Details

Official title: A Randomized, Double-blind, Placebo and Positive Controlled, Parallel Group Trial to Investigate the Effect of Multiple Doses of NOMAC-E2 on QT/QTc Interval in Healthy Women

Study design: Allocation: Randomized, Endpoint Classification: Safety Study, Intervention Model: Parallel Assignment, Masking: Double Blind (Subject, Investigator, Outcomes Assessor)

Primary outcome:

Investigate whether once daily multiple therapeutic and supra-therapeutic doses of NOMAC-E2 prolong the mean QTcF interval at steady state to the threshold of regulatory concern compared to placebo

Establish assay sensitivity after single dose of 400 mg moxifloxacin

Secondary outcome:

evaluate the relation between steady state concentrations of NOMAC, time matched change from baseline in E1 and E2 and the QTcF intervals after multiple dosing of NOMAC-E2

Investigate safety and tolerability of the various treatments
