About this study

Official title: A Randomized, Double-blind Study Evaluating the Influence of Morphine on Pharmacokinetics and Pharmacodynamics of Ticagrelor and Its Active Metabolite (AR-C124910XX) in Patients With ST-segment Elevation Myocardial Infarction and Non-ST-segment Elevation Myocardial Infarction.

The purpose of the IMPRESSION study is to determine whether intravenous administration of morphine prior to ticagrelor administration in ST-segment elevation myocardial infarction (STEMI) patients and in non-ST-segment elevation myocardial infarction (NSTEMI) patients alters the plasma concentrations of ticagrelor and its active metabolite and whether it is associated with any negative impact on the antiplatelet effect of ticagrelor.

Read the detailed description

The European Society of Cardiology and American Heart Association guidelines recommend use of morphine as a treatment of choice for pain relief in STEMI patients. However, this recommendation, although strong, is only based on expert consensus (class of recommendation I, level of evidence C). Morphine, apart from its analgesic effects, also alleviates the work of breathing and reduces anxiety. On the other hand, despite its favorable analgesic and sedative actions, morphine also exerts adverse effects, which include hypotension, bradycardia, respiratory depression, vomiting and reduction of gastrointestinal motility. Some of the previously listed morphine's side effects could affect the intestinal absorption and thus pharmacokinetics and pharmacodynamics of orally administered drugs which are concomitantly used with morphine. At present, no pharmacokinetic and pharmacodynamic data regarding the concurrent use of morphine and P2Y12 blockers in the STEMI or NSTEMI setting are available. Therefore, evidence-based verification of morphine's influence on pharmacokinetics and pharmacodynamics of ticagrelor and its active metabolite (AR-C124910XX) could provide a valuable insight in the knowledge regarding modern acute myocardial infarction management.

Predefined subanalysis: aimed to investigate which one of platelet reactivity assessment methods utilized in the study (VASP assay, MEA, LTA, VerifyNow) best reflects concentration of ticagrelor and its active metabolite (AR-C124910XX).

Since there is no reference study examining pharmacokinetics of ticagrelor in STEMI or NSTEMI patients, we decided to perform an internal pilot study of approximately 30 patients (15 patients for each arm) for estimating the final sample size.

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Morphine and Ticagrelor in people with ST-segment Elevation Myocardial Infarction and Non-ST-segment Elevation Myocardial Infarction, run by Collegium Medicum w Bydgoszczy at 1 site in Poland.

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 23 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 12 Sep 2017. 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 Poland. 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. Some participants in this study may receive a placebo. 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?

Yes. Results are posted in the registry (first posted 3 Mar 2016). 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?

Area Under the Plasma Concentration-time Curve for Ticagrelor (AUC 0-12h) (time frame: prior to the initial dose and 30min, 1h, 2h, 3h, 4h, 6h, 12h post dose). 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 NCT02217878, 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 12 Sep 2017; AzTrials last refreshed its copy on 8 Nov 2026.
