Study summary

Primary Objective:

  • To demonstrate the superior efficacy (composite of all-cause death + Myocardial Infarction (MI)) of Otamixaban to Unfractionated Heparin (UFH) + Eptifibatide

Secondary Objectives:

  • To demonstrate the superior efficacy (composite of all-cause death + MI + any stroke) of Otamixaban as compared to UFH + Eptifibatide
  • To document the effect of Otamixaban on rehospitalization or prolongation of hospitalization due to a new episode of myocardial ischemia/myocardial infarction as compared to UFH + eptifibatide
  • To document the effect on mortality (all cause death) of Otamixaban as compared to UFH + eptifibatide
  • To document the safety of Otamixaban as compared to UFH + eptifibatide
  • To document the effect of Otamixaban on thrombotic procedural complications during the index Percutaneous Coronary Intervention (PCI) as compared to UFH + eptifibatide
Read the detailed description

Up to the interim analysis, patients are randomized to one of the Otamixaban arms or the control arm (UFH + Eptifibatide). Then after interim analysis, patients will be randomized to the continued Otamixaban arm (per Data Monitoring Committee (DMC) decision based on interim analysis results) or the control arm (UFH + Eptifibatide). Except the DMC, all participants will remain blinded to this decision until the end of study.

The total duration of the study period per subject will range between 30 days and 180 days. Study end date being the Day 30 visit of the last randomized patient, follow up will be until Day 180 or study end date whichever comes first.

Inclusion criteria

Patient with non-ST-segment elevation Acute Coronary Syndrome (NSTE-ACS) with:

  1. Ischemic symptoms (chest pain or equivalent) at rest ≥ 10 minutes within 24 hours of randomization,

    AND

  2. One of the two following criteria:

    • New ST-segment depression ≥ 0.1 mV (≥1 mm), or transient (\< 30 minutes) ST-segment elevation ≥ 0.1 mV (≥ 1 mm) in at least 2 contiguous leads on the ,
    • Elevation of cardiac biomarkers within 24 hours of randomization, defined as elevated troponin T, troponin I, or CK-MB level above ,

    AND

  3. Planned to have a coronary angiography (followed, when indicated, by PCI) as early as possible (after at least 2 hours of treatment with study drug) and within 36 hours (at the latest on Day 3, if justified),

    AND

  4. obtained in writing.

Exclusion criteria

Exclusion criteria:

  • Revascularization procedure already performed for the qualifying event Acute ST-segment elevation MI.
  • Patient having received curative dose of anticoagulant treatment (including UFH, LMWH, or bivalirudin) for more than 24 hours prior to randomization or who have been treated by abciximab.
  • Inability to discontinue current anticoagulation in order to transition to Products according to the specified transition timing.
  • Patient who can not be treated by aspirin and clopidogrel (or any other oral antiplatelet agent) according to their local labeling.
  • Patient who cannot be treated with eptifibatide according to the national labeling (when available). In countries where eptifibatide is not approved the reference label to be considered is either the European labeling or the US labeling
  • Patient who cannot be treated with unfractionated heparin according to the national labeling.
  • Allergy to otamixaban.

The above information is not intended to contain all considerations relevant to a patient's potential participation in a clinical trial.

Terms in these criteria, in plain language(4)

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.

ECG (electrocardiogram)

A recording of the heart’s electrical activity, taken with stickers on the chest, arms and legs. It takes a few minutes and does not hurt.

ULN (upper limit of normal)

The top of the normal range for a blood test, as set by the laboratory that runs it. Each lab prints its own range next to your result.

“≤ 2.5 × ULN” means the result can be up to two and a half times that top value.

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.

Investigational drug or device

A drug or device being studied in a clinical trial.

It may be new, or already approved and being studied for another use, dose or form. Criteria often leave out people who took part in another study of one within a recent period, commonly 30 days or five half-lives.
