Trial summary

Statins inhibit hydroxy-methylglutaryl coenzyme A (HMG-CoA) reductase which catalyzes the rate-limiting step in cholesterol synthesis. This in turn leads to reductions in concentrations of low-density lipoprotein (LDL) cholesterol and C-reactive protein which reduces the risk of incident atherosclerotic events among… Read more about this study

About this study

Statins inhibit hydroxy-methylglutaryl coenzyme A (HMG-CoA) reductase which catalyzes the rate-limiting step in cholesterol synthesis. This in turn leads to reductions in concentrations of low-density lipoprotein (LDL) cholesterol and C-reactive protein which reduces the risk of incident atherosclerotic events among individuals both with and without a history of atherosclerotic cardiovascular Several pilot studies have suggested potential benefits of taking statin in the evening rather than in the morning.

The primary objective of this study is to examine whether statin administration at bedtime versus in the morning provides a superior reduction in the incidence of major adverse cardiovascular events among patients with or without established atherosclerotic cardiovascular disease, who are already taking statin.

Read the detailed description

The study is a pragmatic, registry-based, open-label, randomized controlled trial combining the utilization of the Danish nationwide health registries and the official Danish electronic letter system (Digital Post/eBoks) into an innovative, decentralized trial requiring no study visits from participants. The nationwide health registries will be used for identification of potential participants and data collection, including baseline information and follow-up data, while the electronic letter system will be used for sending recruitment letters and communicating with participants. Study participants will provide electronic informed consent from home before inclusion and randomization.

The trial will include patients currently in statin treatment regardless of the presence or absence of established cardiovascular disease. Participants will be randomized 1:1 to either statin administration at bedtime or in the morning. The trial is event-driven.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Statin in the evening (such as Simvastatin, Atorvastatin, Rosuvastatin, Pravastatin)Drug

    Participants will be instructed to take their Statin daily at approx. 8PM-12AM.

  • Statin in the morning (such as Simvastatin, Atorvastatin, Rosuvastatin, Pravastatin)Drug

    Participants will be instructed to take their statin upon awakening/or with their breakfast (approx. 6AM-10AM).

What is being measured

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

  1. Composite of hospitalization for myocardial infarction, hospitalization for stroke or cardiovascular death

    For Hospitalizations: Inpatient, at least 1 night

    Measured: Will be assessed in a time-to-first-event approach from date of randomization until end of study (up til 5 years).

Secondary outcomes (4)
  1. Hospitalization for myocardial infarction

    Inpatient, at least 1 night

    Measured: Will be assessed in a time-to-first-event approach from date of randomization until end of study (up til 5 years).

  2. Hospitalization for stroke

    Inpatient, at least 1 night

    Measured: Will be assessed in a time-to-first-event approach from date of randomization until end of study (up til 5 years).

  3. Cardiovascular death

    Measured: Will be assessed in a time-to-first-event approach from date of randomization until end of study (up til 5 years).

  4. All-cause death

    Measured: Will be assessed in a time-to-first-event approach from date of randomization until end of study (up til 5 years).

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Statin in the evening (such as Simvastatin, Atorvastatin, Rosuvastatin, Pravastatin) and Statin in the morning (such as Simvastatin, Atorvastatin, Rosuvastatin, Pravastatin) in people with Cardiovascular Diseases (CVD) and Drug Effect, run by Tor Biering-Sørensen at 1 site in Denmark.

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 3 inclusion and 1 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: opening soon, as of the sponsor's last update on 4 Mar 2025. 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 Denmark. 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 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

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

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

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

Contact Manan Pareek, MD and PhD (+4525536900, mananpareek@dadlnet.dk), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Composite of hospitalization for myocardial infarction, hospitalization for stroke or cardiovascular death (time frame: Will be assessed in a time-to-first-event approach from date of randomization until end of study (up til 5 years).). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 4 Mar 2025.
