Study summary

The ELECTRA pilot study is a randomized, open-label, pharmacokinetic and pharmacodynamic trial designed to evaluate the effect of ticagrelor maintenance dose reduction on platelet inhibition in stable patients who recently underwent acute myocardial infarction and were treated with percutaneous coronary intervention.

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  • provision of prior to any study specific procedures
  • diagnosis of acute ST-segment elevation myocardial infarction or acute non-ST-segment elevation myocardial infarction according to the Third Universal Definition of Myocardial Infarction
  • index event treatment with percutaneous coronary intervention
  • male or non-pregnant female, aged 18-80 years old

Exclusion criteria

Exclusion Criteria:

  • for ticagrelor
  • further coronary revascularization planned during the first 45 days after myocardial infarction
  • indications for chronic treatment with oral anticoagulant or low-molecular-weight heparin
  • active bleeding
  • history of intracranial hemorrhage
  • recent gastrointestinal bleeding (within 30 days)
  • history of coagulation disorders
  • history of moderate or severe hepatic impairment
  • history of major surgery or severe trauma (within 3 months)
  • active neoplastic disease
  • patient requiring dialysis
  • chronic inflammatory disease
  • current therapy with strong inhibitors or strong CYP3A inducers
Terms in these criteria, in plain language(3)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Contraindication

A reason a treatment, test or procedure should not be given to a particular person, such as an allergy, another illness or a medicine they take.

CYP3A (CYP3A4) inhibitors and inducers

CYP3A is a group of enzymes, mainly CYP3A4, in the liver and gut that break down many medicines. Some medicines, supplements and foods (grapefruit, St John’s wort) slow them down or speed them up, which changes how much of a study drug stays in the body.

Studies list them so they can be avoided or switched; bring a list of everything you take, including supplements.

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Ran from Aug 2017 to primary completion in Feb 2018, 6 months.

Of 33 non-industry phase 3 interventional studies under Myocardial Infarction, half reached primary completion within 41 months of starting (the median), counting those still running; a quarter within 24 and three quarters within 73. This study's 6 months is below that.

Counting every sponsor, half of 57 studies reached it within 43 months; a quarter within 30 and three quarters within 77.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Apr 21, 2023, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
