Evaluation of Possible Effects on the QTc Interval of CHF 4226 pMDI in Healthy Volunteers (CT14)

March 26, 2009 updated by: Chiesi Farmaceutici S.p.A.

A Randomized, Double Blind, Single Dose, Positive and Placebo Controlled, Crossover Study of the Effects of Inhaled Carmoterol, at the Proposed Therapeutic and Supratherapeutic Doses, on the QTc Intervals in Healthy Subjects

The purpose of this study is to evaluate the effect of single doses of therapeutic and supratherapeutic doses of inhaled CHF 4226 pMDI on ventricular repolarization in healthy subjects compared with placebo.

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

The secondary purposes of this study are to 1) determine if there is a relationship between the duration of the QTc intervals and the plasma concentrations of carmoterol; 2) expand the available information on plasma pharmacokinetics and urine excretion for inhaled carmoterol at the proposed therapeutic and supra-therapeutic doses; and 3) generate additional safety information.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4.

Participation Criteria

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.

Exclusion Criteria:
