About this study

Official title: A Randomized, Double-Blind, Placebo-Controlled, Forced Titration Study to Assess the Efficacy and Safety of Omacor, Co-Administered With Open-Label Atorvastatin Therapy, in Hypertriglyceridemic Subjects

The purpose of this study is to evaluate the efficacy and safety of Omacor (omega-3-acid ethyl esters) combined with atorvastatin for lowering non-high-density lipoprotein cholesterol (non-HDL-C) in hypertriglyceridemic subjects.

Read the detailed description

Randomized, double-blind, placebo-controlled, parallel-group study design with eleven clinic visits (one screening visit, three lead-in/baseline visits, and seven treatment visits) After a 4-week diet only lead-in period, subjects with a triglyceride (TG) level in the high to very high range and with non-HDL-C level above NCEP ATPIII goals will be randomized to receive either open-label atorvastatin 10 mg per day plus double-blinded Lovaza 4g (4 x 1g capsules) per day OR open-label atorvastatin 10 mg per day plus a double-blinded matching placebo (4 corn oil capsules per day) for 8 weeks After the initial 8-week treatment period, the dose of open-label atorvastatin will be titrated to 20 mg per day (with the Lovaza or matching placebo corn oil doses remaining at 4 capsules per day) for an additional 4 weeks At Week 12, a second open-label titration to 40 mg of open-label atorvastatin per day will be maintained for an additional 4 weeks (again with the Lovaza or matching placebo corn oil doses remaining at 4 capsules per day)

    Measured: Baseline and Week 8

  3. Percent Change in Low Density Lipoprotein (LDL) Cholesterol (Beta-quantification) From Baseline to Week 8 During 10 mg Atorvastatin Treatment Period

    LDL - A complex of lipids and proteins, with greater amounts of lipid than protein, that transports cholesterol in the blood. High levels are associated with an increased risk of atherosclerosis and coronary heart disease.

    Measured: Baseline and Week 8

  4. Percent Change in Triglycerides From Baseline to Week 8 During 10 mg Atorvastatin Treatment Period

    Triglycerides - A naturally occurring ester of three fatty acids and glycerol that is the chief constituent of fats and oils.

    Measured: Baseline and Week 8

  5. Percent Change in Very Low Density Lipoproteins (VLDL) Cholesterol From Baseline to Week 8 During 10 mg Atorvastatin Treatment Period

    VLDL - very-low-density lipoprotein: a plasma lipoprotein with a high lipid content, associated with atherosclerosis.

  6. Percent Change in Apolipoprotein-A-1 From Baseline to Week 8 During 10 mg Atorvastatin Treatment Period

    Apolipoprotein A1 - major protein component of high density lipoprotein (HDL) in plasma. The protein promotes cholesterol efflux from tissues to the liver for excretion.

    Measured: Baseline and Week 8

  7. Percent Change in Apolipoprotein C-III From Baseline to Week 8 During 10 mg Atorvastatin Treatment Period

    Apolipoprotein C-III (APOC3) is a very low density lipoprotein (VLDL) protein. APOC3 inhibits lipoprotein lipase and hepatic lipase; it is thought to delay catabolism of triglyceride-rich particles.

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Lovaza (omega-3-acid ethyl esters) [formerly known as Omacor] plus atorvastatin and atorvastatin in people with Hypertriglyceridemia, run by GlaxoSmithKline.

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 4 inclusion and 9 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 2 Feb 2017. Status can change between updates, so confirm with the study contact before making plans.

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 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

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

Are results available for this study?

Yes. Results are posted in the registry (first posted 12 May 2009). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Percent Change in Non-High Density Lipoprotein Cholesterol (Non-HDL-C) From Baseline to Week 8 During 10 mg Atorvastatin Treatment Period (time frame: Baseline and Week 8). 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 NCT00435045, which also lists 2 linked publications.

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 2 Feb 2017.
