What is being measured

The primary outcome is the main question the study is designed to answer.

  1. The plasma concentrations of warfarin and ISIS 681257 will be measured at each individual time point.

    To evaluate the effect of multiple doses of ISIS 681257 40 mg subcutaneous injections on the pharmacokinetics of a single oral dose of warfarin in healthy adult subjects.

    Measured: Each day for days 1-10 and 15-45

Secondary outcomes (5)
  1. The safety of ISIS 681257 by the incidence of treatment-emergent adverse events.

    To evaluate the safety and tolerability of multiple doses of ISIS 681257 40 mg subcutaneous injections when coadministered with a single oral dose of warfarin in healthy adult subjects.

    Measured: 45 days

  2. Prothrombin Time will be measured by testing blood samples at each individual time point.

    To evaluate the effect of multiple doses of ISIS 681257 40 mg subcutaneous injections on the pharmacodynamics (anticoagulant activity) of a single oral dose of warfarin in healthy adult subjects.

    Measured: Each day for days 1-7 and 15-21

  3. International normalized ratio will be measured at each individual time point by comparing prothrombin time to the normal mean prothrombin time.

    To evaluate the effect of multiple doses of ISIS 681257 40 mg subcutaneous injections on the pharmacodynamics (anticoagulant activity) of a single oral dose of warfarin in healthy adult subjects.

    Measured: Each day for days 1-7 and 15-21

  4. Activated partial thromboplastin time will be measured by testing blood samples at each individual time point.

    To evaluate the effect of multiple doses of ISIS 681257 40 mg subcutaneous injections on the pharmacodynamics (anticoagulant activity) of a single oral dose of warfarin in healthy adult subjects.

    Measured: Each day for days 1-7 and 15-21

  5. The plasma concentrations of warfarin and ISIS 681257 will be measured at each individual time point.

    To evaluate the effect of a single dose of warfarin on the pharmacokinetics of a single subcutaneous 40 mg injection of ISIS 681257 in healthy adult subjects.

    Measured: Each day for days 1-10 and 15-45

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing ISIS 681257 and Warfarin in people with Elevated Lipoprotein(a) and Cardiovascular Diseases, run by Akcea Therapeutics at 1 site in Canada.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 7 inclusion and 10 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 5 Apr 2018. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Canada. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

The plasma concentrations of warfarin and ISIS 681257 will be measured at each individual time point. (time frame: Each day for days 1-10 and 15-45). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT03426033, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 5 Apr 2018.
