Study summary

The standard and most common therapy is anticoagulation with heparin according to activated partial thromboplastin time (aPTT) during extracorporeal membrane oxygenation (ECMO) support. The study will focus on evaluating the efficacy and safety of new anticoagulants on ECMO, namely argatroban and enoxaparin in lower doses controlled according to targeted antiIIa and antiXa markers.

Read the detailed description

This is a phase II academic clinical trial designed to evaluate the effect of argatroban and enoxaparin used to enable ECMO support in critically ill patients. The population will consist of patients hospitalised at University Hospital Ostrava and University Hospital Motol Prague. After signing the Informed Con-sent to participate in the study, treatment will be based on the patient's clinical condition and the decision of the attending physician. The study participants will be patients diagnosed with heart failure (including cardiac arrest) or pulmonary failure, adult men and women, using argatroban or enoxaparin.

Inclusion criteria

  • ECMO support with anticoagulation using argatroban/enoxaparin
  • Age ≥ 18 years
  • Obtaining in accordance with the procedure specified in the protocol

Exclusion criteria

Exclusion Criteria:

  • Enrolment in the lung transplant program at Motol University Hospital
  • Known to the components of the evaluated products
  • Allergic reaction to the active ingredients of the evaluated products
  • Pregnancy and breastfeeding
Terms in these criteria, in plain language(2)

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.

Hypersensitivity

An allergy, or another reaction of the immune system, to a substance. “Hypersensitivity to the study drug” means a known allergic reaction to it — not every side effect a medicine can have.

What researchers measure

Primary outcomes

  1. Safety of bleeding complications

    Bleeding Academic Research Consortium (BARC) score will be used to assess bleeding complication.

    Time frame: During ECMO, up to 4 weeks

  2. Safety of thrombotic complications

    ECMO pressures (e.g. oxygenator changes) will be used to assess thrombotic complications

    Time frame: During ECMO, up to 4 weeks

Secondary outcomes

  1. Mortality

    Hospital mortality and 6-month mortality will be assessed

    Time frame: 6 months

  2. Cerebral Performance Category (CPC) score

    Cerebral Performance Category (CPC) score will be assessed on the 30th day after ECMO initiation

    Time frame: 30 days

  3. Quality of Life questionnaires score - EQ-5D-5L

    Quality of Life will be assessed using the EQ-5D-5L questionnaire 6 months after ECMO initiation. The EQ-5D-5L questionnaire is a quick, 5-dimension preference-based tool (mobility, self-care, activities, pain, anxiety) with a visual analog scale (VAS).

    Time frame: 6 months

  4. Quality of Life questionnaires score - SF36

    Quality of Life will be assessed using the SF36 questionnaire 6 months after ECMO initiation. SF-36 is a comprehensive 36-item survey assessing eight health domains.

    Time frame: 6 months
