A Double-Blind, Cross-Over Placebo-Controlled and Active-Controlled Trial To Evaluate The Effect Of A Supratherapeutic Dose Of MK-8189 On The QTc Interval In Participants With Schizophrenia

Merck Sharp & Dohme LLC·interventional·Posted Jun 8, 2023·Updated Apr 29, 2026

In Brief

A Phase 1 clinical trial evaluating Elpipodect, Moxifloxacin, and 1 other intervention for Schizophrenia. Completed, enrolled 107 participants across 4 sites.

Detailed Summary

The primary purpose of this study to evaluate the effect of a supratherapeutic dose of 80 mg elpipodect on the QT interval corrected for heart rate (QTc interval) and to assess the safety and tolerability of multiple once-daily doses of elpipodect in participants with schizophrenia. The effects of 3 treatment sequences 1) elpipodect (48 mg \[Day 1\] and 80 mg \[Day2\]); 2) standard image placebo (Day 1) and moxifloxacin 400 mg (Day 2); and 3) elpipodect placebo (Day 1 and Day 2) were assessed with 5-day washout intervening sequence. Participants received all treatments in a counter-balanced order according to 1 of 6 possible treatment sequences. The primary hypothesis is that the administration of an 80 mg elpipodect dose on Day 2 does not prolong the QTc interval to a clinically significant degree. Specifically, the true mean difference (elpipodect - placebo) in QTc change from baseline is less than 10 milliseconds (msec).
