A Study to Evaluate the Effect of Volanesorsen on Cardiac Repolarization Conducted in Healthy Volunteers

January 13, 2022 updated by: Ionis Pharmaceuticals, Inc.

A Randomized, Placebo-Controlled, Four-Period Crossover, Study to Evaluate the Effect of Volanesorsen on the QTc Interval Using a Therapeutic and Supra-Therapeutic Dose Compared With Placebo in Healthy Volunteers: a Thorough QT Study

The primary objective of this study is to assess the corrected QT interval (QTc) effect of volanesorsen (ISIS 304801) administered as a 300 mg subcutaneous (SC) therapeutic and a 300 mg intravenous (IV; 2-hour infusion) supra-therapeutic dose relative to placebo in healthy adult male and female subjects.

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.

Study Type

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 55 years (ADULT)

Accepts Healthy Volunteers

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
Measure Description
Time Frame
Placebo corrected change from baseline in QTcF (corrected Frederica's CT Interval)
Time Frame: 24 Hours
ECG monitoring up to 24 hours post dose
24 Hours

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
Measure Description
Time Frame
Placebo corrected change from baseline heart rate (HR, PR and QRS)
Time Frame: 24 Hours
ECG monitoring 24 hours post dose
24 Hours

Other Outcome Measures

Other Outcome Measures

For clinical trials, a planned measurement described in the protocol that is used to determine the effect of an intervention/treatment on participants. For observational studies, a measurement or observation that is used to describe patterns of diseases or traits, or associations with exposures, risk factors, or treatment. Types of outcome measures include primary outcome measure and secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
