Trial Outcomes & Findings for Thorough QT Study of Intravenous Amisulpride (NCT NCT02661594)

NCT ID: NCT02661594

Last Updated: 2018-11-29

Results Overview

Maximal mean placebo-corrected change from baseline of QTcF (QT interval corrected for heart rate using the Fridericia formula) for single 5 mg and 40 mg iv doses of APD421. At each time point (2 mins, 8 mins, etc) the QTcF is compared to the pre-dosing "baseline" value, in order to calculate the change in QTcF (ΔQTcF). The value of ΔQTcF at each time point is then compared against the same time point for a placebo infusion, and the difference is calculated (ΔΔQTcF).

Participant Flow

Forty (40) healthy, non-elderly, Caucasian and Japanese, male or female subjects were planned to enter the study. At least 10 subjects were to be Japanese and at least 40% of subjects for both races were to be male.

Forty (40) healthy subjects entered the study. One subject voluntarily withdrew after Period 1 (moxifloxacin 400 mg) and another subject was withdrawn due to severe non-compliance with the protocol after receiving APD421 5 mg and 40 mg.
