Effects of Three Single Oral Doses of Trazodone on the QTc Interval Duration in Healthy Volunteers

July 29, 2020 updated by: Aziende Chimiche Riunite Angelini Francesco S.p.A

Single Centre, Single Dose, Randomised, Negative and Positive-controlled, Double-blind Trazodone vs. Negative Control (Placebo), Open-label vs. Positive Control (Moxifloxacin), 5-way Cross-over QT/QTc Study

The present study has been designed to evaluate the effect of three doses of trazodone (20, 60 and 140 mg), in comparison to placebo, on the QT/QTc interval of healthy volunteers. Trazodone oral drops 6% formulation has been selected in order to evaluate the three doses using the same formulation, because the lowest available strength for the tablet formulations is 50 mg. According to the E14 guideline on the evaluation of QT/QTc interval prolongation and proarrhythmic potential of antiarrhytmic drugs, a negative control (placebo) and a positive control (moxifloxacin) will also be assessed.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Twenty (20) healthy volunteers (about 50% males and 50% females) will be randomised.

Primary end-point:

  • Evaluation of the relationship between the plasma concentration of trazodone (free base) and the change from baseline in QTc, placebo-adjusted and corrected for HR based on the Fridericia correction method (QTcF) method (∆∆QTcF).
  • Trazodone can be declared to have no influence on QTc if the null hypothesis, that the upper bound of the two-sided 90% CI of the predicted mean placebo corrected change from baseline for QTcF is greater than 10 msec at the observed mean Cmax for the therapeutic dose of trazodone, can be rejected.

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.
