Ticagrelor Removal Study Using CytoSorb® 300 mL Device During CPB in Patients Undergoing Emergent Cardiothoracic Surgery (CyTation)

January 21, 2022 updated by: CytoSorbents Europe GmbH

A Prospective, Open, Multi-center, Single-arm Study to Demonstrate the Feasibility of the CytoSorb® 300 mL Device to Remove Ticagrelor During Cardiopulmonary Bypass in Patients on Ticagrelor Undergoing Emergent Cardiothoracic Surgery

The aim of CyTation is to demonstrate intra-operative removal of ticagrelor by CytoSorb® hemadsorption in patients on ticagrelor undergoing emergent cardiothoracic surgery requiring CPB, using platelet reactivity to adenosine diphosphate (ADP) as a pharmacodynamics surrogate measure of ticagrelor levels in blood.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Terminated

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.

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. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

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

Genders Eligible for Study

All

Description

Inclusion Criteria:

  • Signed informed consent
  • Males and females aged ≥18 years
  • Patients treated with ticagrelor
  • Emergency Coronary Artery Bypass Graft (CABG) surgery
  • Cardiothoracic surgery requiring CPB ≤24 hours following the last dose of ticagrelor

Exclusion Criteria:

  • Any cardiothoracic surgery >24 hours after last dose of ticagrelor
  • Resuscitation
  • Any pre-operative coagulopathy unrelated to ticagrelor or standard of care (SoC) to undergo surgery with CPB
  • Sepsis (according to Sepsis 3.0 definition)
  • Malignant tumor
  • Left ventricular ejection fraction (LVEF) < 20%
  • History or presence of significant pulmonary, hepatic, renal, hematologic, gastrointestinal, endocrine, immunologic, neurologic, or psychiatric disease which, in the opinion of the Investigator, increases risk to the patient or could confound the results of the study
  • Presence of end-stage renal disease or currently receiving renal replacement therapy
  • Patients with a history of major organ transplantation
  • Patients in acute sickle cell crisis
  • Patients concurrently requiring immunosuppressive therapy, with the exception of corticosteroids, or who are profoundly immune suppressed (e.g. CD4 < 200 or neutropenia with ANC < 1000/μL)
  • Women of childbearing potential with a positive pregnancy test performed during the current admission or who are lactating. Women are considered not of child bearing potential if they have been sterilized at least 6 months prior to the study or if they are post-menopausal, defined as amenorrhea for at least 12 months

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Platelet reactivity
Time Frame: 8 hours
Proportion of patients with post-operative platelet reactivity to ADP above the level associated with increased bleeding risk (≥ 22 ADP-induced platelet aggregation units (AUC in units)) measured on the MEA platform immediately after CPB compared to immediately before CPB.
8 hours
