About this study

Official title: Chronotherapy With Aspirin for Reduction of Cardiovascular Disease

This study will be a comparative effectiveness research to determine the difference in major adverse cardiovascular events between the group with aspirin after awakening and placebo before bedtime and the group with placebo after awakening and aspirin before bedtime.

Read the detailed description

Aspirin is the cornerstone of preventive cardiovascular disease (CVD) treatment and bedtime intake of aspirin (chronotherapy) has been shown to reduce morning activity of platelets. It has been shown that platelet reactivity follows a clear circadian rhythm, with a peak of platelet reactivity during the morning (6-12 AM). Importantly, studies have shown in meta-analyses that high platelet activity is predictive of adverse cardiovascular outcomes in patients with stable CVD. Given this knowledge, it is highly likely that the morning peak of platelet reactivity contributes to the morning peak of cardiovascular events and that reduction of morning platelet activity prevents cardiovascular events during morning hours. This may be achieved by intake of aspirin at bedtime instead of on awakening. This study will be a comparative effectiveness research to determine the difference in major adverse cardiovascular events between the group with aspirin after awakening and placebo before bedtime and the group with placebo after awakening and aspirin before bedtime.

What participants receive

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

  • placebo after awakening + aspirin before bedtimeOther

    Also called Acetylsalicylic acid Cardio Teva 80 mg, intake before bedtime

    determine the difference in major adverse cardiovascular events between the group with aspirin after awakening and placebo before bedtime and the group with placebo after wakening and aspirin before bedtime.

  • aspirin after awakening + placebo before bedtimeOther

    Also called Acetylsalicylic acid Cardio Teva 80 mg, intake after awakening

    determine the difference in major adverse cardiovascular events between the group with aspirin after awakening and placebo before bedtime and the group with placebo after wakening and aspirin before bedtime.

Study groups in NCT04132791
Study groupRoleWhat they receive
aspirin after awakening + placebo before bedtimeOtherAcetylsalicylic acid 80 mg once daily, orally. Intake in de morning after awakening. Participants already use acetylsalicylic acid 80 mg once daily due to secondary prevention of cardiovascular disease. Placebo tablet once daily will be added to their medication. The placebo tablet will be taken before bedtime, orally. The placebo is given throughout the study.
Receives: Other: aspirin after awakening + placebo before bedtime
placebo after awakening +aspirin before bedtimeExperimentalAcetylsalicylic acid 80 mg once daily, orally. The time will be changed form morning to bedtime. Participants already use acetylsalicylic acid 80 mg once daily due to secondary prevention of cardiovascular disease. Placebo tablet once daily will be added to their medication. The placebo tablet will be taken after awakening, orally. The placebo is given throughout the study.
Receives: Other: placebo after awakening + aspirin before bedtime

What is being measured

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

  1. Incidence rate of major adverse cardiovascular events

    the difference in number of participants with a major adverse cardiovascular events, defined as the composite of death from cardiovascular causes, nonfatal myocardial infarction, or nonfatal stroke, transient ischemic attack, need for repeat revascularízation by redo-CABG or repeat percutaneous intervention.

    Measured: maximum of 4 years follow up

Secondary outcomes (3)
  1. Comparing the incidence rate of major cardiovascular events between the two groups in the morning (6-12), evening (12-21) and night (21-6).

    It is expected that bedtime aspirin reduces the number of participants with primary outcome (major cardiovascular events) more during morning hours (6-12h) compared with the rest of the day. So we will compare the mornig events, afternoon/evening and night events between the two groups and compare the difference.

    Measured: maximum of 4 years follow up

  2. Incidence rate of side-effects between the 2 groups

    the difference between the 2 groups of the number of participants that experience side-effects (e.g. bleeding, gastrointestinal symptoms)

    Measured: maximum of 4 years follow up

  3. cost-effectiveness of the intervention

    Comparing the relative costs and outcomes (effects) between the 2 groups. Data from questionnaire (use of health care) and data from the primary and secondary health care systems. We can compare the use of health care between the two groups en we can calculate the difference in cost between the two groups. So we can estimate if our intervention is cost-effective.

    Measured: maximum of 4 years follow up

Questions about this trial

What is this clinical trial studying?

A study of Cardiovascular Diseases, run by Leiden University Medical Center at 1 site in Netherlands.

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 4 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: stopped early, as of the sponsor's last update on 24 Jun 2022. 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 Netherlands. 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.

Are results available for this study?

The study was stopped early (reason given: stopped prematurely due to too low inclusion rate). Results are not available in the source record.

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?

Incidence rate of major adverse cardiovascular events (time frame: maximum of 4 years follow up). 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 24 Jun 2022.
