Official title

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

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

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).
