Filter by:The primary objective of this study is to evaluate the pharmacokinetic (PK) profile of oral eleclazine and its metabolite, GS-623134, in participants with normal and impaired hepatic function. Participants in the healthy control group will be matched to participants with impaired hepatic function by age (± 5 years), gender, and body mass index (± 10%).
Experimental intervention: electrocardiography. Control intervention: none Duration of intervention per patient/subject: 5 min, observation 6 months Key inclusion criteria: - outpatients after lung transplantation (single, double or combined) - outpatients on the wait list for lung transplantation Key exclusion criteria: • no informed consent
This study will evaluate the effect of oral GS-6615 on QTc interval in healthy adults with dofetilide-induced QTc prolongation.
The primary objective of the study is to evaluate the effect of oral eleclazine (formerly GS-6615) on corrected QT (QTc) interval in participants with long QT2 syndrome.
The primary objective of this research study is to test the hypothesis that late sodium current blocking drugs (mexiletine or lidocaine) can attenuate the effect of hERG potassium channel blocking drugs (dofetilide) on ventricular repolarization (QTc) by shortening early repolarization (J-Tpeakc). The secondary object is to assess the ability of calcium channel block (diltiazem) to reduce the QTc prolongation associated with hERG block (moxifloxacin).
The primary objective of this study is to evaluate the effect of oral eleclazine on mean daytime QTcF interval after 24 weeks of treatment with elecalzine in participants with long QT syndrome Type 3. During the single-blind treatment period (24 weeks), participants will receive eleclazine and/or eleclazine placebo. Following the single-blind treatment period, participants who have not permanently discontinued study drug will be eligible, at the discretion of the investigator, to continue receiving eleclazine during an open-label extension (OLE) phase.
A double-center, randomized, double-blinded, 2-way crossover, placebo-controlled Study: Comparison of single oral dose 400mg Moxifloxacin-induced QT prolongation between healthy Chinese volunteers and Caucasian Volunteers Study Objective:Primary Objective:To compare the difference of ΔΔQTcF (Baseline-adjusted, placebo-corrected effect on QTcF) between Chinese group and Caucasian group under the same exposure (Cmax) of Moxifloxacin.Secondary Objectives:1)To compare the difference of ΔΔQTcF, heart rate, PR, RR, QRS and Moxifloxacin plasma concentration between Chinese group and Caucasian group.2)To compare slopes of Moxifloxacin plasma Concentration/QTcF value between healthy Chinese volunteers and Caucasian Volunteers.
The purpose of this study is to determine the true incidence of long QT (LQT) amongst a large cohort of subjects diagnosed with unilateral (right/left) or bilateral sensorineural hearing loss.
A prospective, observational study in a university hospital (UZ Leuven). Patients are included when they are treated with a potentional QT-prolonging drug: haloperidol for delirium, antibiotics (moxifloxacin, levofloxacin, azithromycin, clarithromycin, erythromycin, co-trimoxazole), antimycotics (ketoconazole, itraconazole, fluconazole, voriconazole), methadone, tacrolimus and oral oncolytics. An ECG is taken before the administration of the drug and 3-5 days after starting the drug to investigate the change in duration of the QTc-interval. Risk factors for developing QT-prolongation will be documented. Together with ECG2, an additional blood sample will be collected to measure the blood concentration of the drug.
Observational study in 6 psychiatric hospitals in Flanders. Patients are included when a QT-prolonging drug is added to a medication profile that already contains a potential QT-prolonging drug. An ECG is taken before the administration of the new drug and a week after starting the new drug to investigate the change in duration of the QTc-interval. Risk factors for developing QT-prolongation and blood concentrations of potassium and creatinine are documented.
