A Study to Determine the Effects of Multiple Doses of Mipomersen (200 mg SC) on the Pharmacodynamics and Pharmacokinetics of Single-dose Warfarin

August 1, 2016 updated by: Kastle Therapeutics, LLC

A Drug-Drug Interaction Study to Assess the Effects of Multiple Doses of Mipomersen (200 mg SC) on Single-Dose Warfarin (25 mg) Pharmacodynamics and Pharmacokinetics in Healthy Adult Subjects

The purpose of this study is to assess how blood clotting and thinning time is effected when a single dose of warfarin is given alone and when a single dose of warfarin is given with mipomersen; to assess the blood levels of a single dose of warfarin, a single dose of mipomersen, and a single dose of warfarin when given with mipomersen; and to assess the safety of mipomersen when given with or without warfarin.

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

This will be a Phase 1, open-label, single-sequence, 2-period, crossover study to determine the effect of multiple doses of mipomersen (200 mg SC given every other day for a total of 4 doses) on the PD and PK of warfarin and to evaluate the PK of mipomersen when administered alone and in combination with warfarin. Subjects will be admitted to the clinic on Day -1 until discharge from the clinic on Day 18 and return for outpatient visits on Days 19, 20, and 78. All subjects will receive a single 25-mg oral dose of warfarin given alone on Day 1 (designated the reference treatment). All subjects will then receive 200-mg SC doses of mipomersen given every other day on Days 8, 10, 12, and 14 (total of 800 mg mipomersen) with a single 25-mg oral dose of warfarin also given on Day 14 (combination designated the test treatment).

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 45 years (Adult)

Accepts Healthy Volunteers

Yes

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
Area under the effect curve (AUC), for INR (international normalized ratio), PT (prothrombin time), and aPTT (activated partial thromboplastin time)

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.
