Hemoadsorption for Prevention of Vasodilatory Shock in Cardiac Surgery Patients With Infective Endocarditis (REMOVE)

March 14, 2025 updated by: Jena University Hospital

Revealing Mechanisms and Investigating Efficacy of Hemoadsorption for Prevention of Vasodilatory Shock in Cardiac Surgery Patients With Infective Endocarditis - a Multicentric Randomized Controlled Group Sequential Trial

Infective endocarditis (IE) is associated with high hospital mortality for various reasons; one of them is circulatory failure in patients who undergo cardiac surgery for IE. One discussed reason underlying circulatory failure during surgery is the release of vasodilatatory mediators and cytokines. This study examines the efficacy and safety of a hemoadsorption filter which is approved for the reduction of the concentration of cytokines in the bloodstream.

Conditions

Conditions

Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

The investigators assume a common standard deviation of 3.8 points and that a 1.4-point lower SOFA score in the Intervention Group is of clinical relevance.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Description

Inclusion Criteria:

  • patients with infective endocarditis (according to DUKE criteria) undergoing cardiac surgery
  • informed consent
  • age ≥18 years

Exclusion Criteria:
