A Placebo-controlled Four Way Crossover Study to Asses the Effect of a Single Oral Dose of NKTR-118 on QTc Interval in Healthy Male Subjects

October 13, 2014 updated by: AstraZeneca

A Single Center, Randomized, Double-blinded, Placebo-controlled, Open-label, Positive-controlled, Four-way Crossover Study to Assess the Effect of a Single Oral Dose NKTR-118 Administration on QTc Interval Compared to Placebo, Using AVELOX (Moxifloxacin) as a Positive Control, in Healthy Male Subjects

The purpose of this study is to evaluate the effects on QTc interval in healthy males when administered a single dose of NKTR-118 compared with placebo and moxifloxacin. (QTc is a specific time interval that can be measured in a heart beat by taking Electrocardiogram (ECG))

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. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

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.

Ages Eligible for Study

18 years to 50 years (Adult)

Accepts Healthy Volunteers

Yes

Genders Eligible for Study

Male

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Time Frame
To evaluate the effect of a single dose of NKTR-118 25 mg and 150 mg on the change in time-matched QTcF intervals compared with placebo
Time Frame: 30 days pre-dose through 4 treatment periods and follow up 71 days post dose.
30 days pre-dose through 4 treatment periods and follow up 71 days post dose.
The effect of a single dose of NKTR-118 25 mg and 150 mg on the change in time-matched QTcF intervals compared with placebo
Time Frame: Follow up 71 days post dose.
Follow up 71 days post dose.

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Time Frame
To evaluate the effect of a single oral dose of moxifloxacin 400 mg on the changes in time-match QTcF intervals compared with placebo, which will be used as supporting data.
