About this study

Official title: Selective C-Reactive Protein Apheresis in Cardiogenic Shock Complicating Acute Myocardial Infarction (CRP-SHOCK Trial)

Cardiogenic shock complicating acute myocardial infarction remains associated with high short-term mortality despite guideline-directed therapy. Systemic inflammation, particularly elevated C-reactive protein (CRP), may contribute to ongoing myocardial injury and organ dysfunction.

The CRP-SHOCK trial is an investigator-initiated, prospective, randomized, open-label, multicenter pilot study evaluating selective CRP apheresis as an adjunct to standard of care in patients with infarct-related cardiogenic shock. Patients are randomized to receive either standard therapy alone or standard therapy plus selective CRP apheresis using the PentraSorb®-CRP system.

The primary objective is to assess the effect of CRP apheresis on the CLIP score at 66 ± 8 hours after randomization. Secondary objectives include clinical outcomes, inflammatory biomarkers, and safety endpoints.

Read the detailed description

Cardiogenic shock following acute myocardial infarction is associated with a high inflammatory response and mortality rates of approximately 40-50% despite early revascularization and intensive care treatment. Experimental and clinical evidence suggests that elevated C-reactive protein (CRP) contributes to myocardial injury, impaired tissue regeneration, and adverse outcomes.

The CRP-SHOCK trial investigates whether selective removal of circulating CRP by apheresis improves short-term risk stratification and clinical outcomes in patients with infarct-related cardiogenic shock. The intervention consists of up to three CRP apheresis sessions initiated within 5 ± 1 hours after randomization and repeated at predefined intervals using the PentraSorb®-CRP system.

The primary efficacy endpoint is the CLIP score at 66 ± 8 hours after randomization. Secondary endpoints include mortality, major adverse cardiovascular events, biomarkers of inflammation and organ function, and safety outcomes such as bleeding, stroke, and infections. The trial is conducted as a multicenter pilot study in Germany and Austria.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. CLIP score

    The CLIP score (Cystatin C, Lactate, Interleukin-6 and N-terminal pro B-type natriuretic peptide [NT-proBNP] score) is a biomarker-based risk score for predicting 30-day mortality in cardiogenic shock complicating acute myocardial infarction. It is calculated via a logistic regression model using the four biomarkers (Cystatin C, Lactate, Interleukin-6, and NT-proBNP), yielding a probability score ranging from 0 to 1 (or 0% to 100% when multiplied by 100). Higher scores indicate a higher probability of 30-day mortality, i.e., a worse outcome.

    Measured: 66 ± 8 hours after randomization

Secondary outcomes (13)
  1. Major adverse cardiovascular events (MACE)

    Composite endpoint of cardiovascular death, non-fatal myocardial infarction, or re-admission for heart failure.

    Measured: 30 days

  2. All-cause mortality

    Death from any cause within 30 days after randomization.

    Measured: 30 days

  3. Cardiovascular mortality

    Death due to cardiovascular causes within 30 days after randomization.

    Measured: 30 days

  4. CLIP score over time

    The CLIP score (Cystatin C, Lactate, Interleukin-6 and N-terminal pro B-type natriuretic peptide [NT-proBNP] score) is a biomarker-based risk score for predicting 30-day mortality in cardiogenic shock complicating acute myocardial infarction. It is calculated via a logistic regression model using the four biomarkers (Cystatin C, Lactate, Interleukin-6, and NT-proBNP), yielding a probability score ranging from 0 to 1 (or 0% to 100% when multiplied by 100). Higher scores indicate a higher probability of 30-day mortality, i.e., a worse outcome.

    Measured: 18 ± 4 hours, 42 ± 6 hours, and 66 ± 8 hours after randomization

  5. Individual components of the CLIP score

    The CLIP score (Cystatin C, Lactate, Interleukin-6 and N-terminal pro B-type natriuretic peptide [NT-proBNP] score) is a biomarker-based risk score for predicting 30-day mortality in cardiogenic shock complicating acute myocardial infarction. It is calculated via a logistic regression model using the four biomarkers (Cystatin C, Lactate, Interleukin-6, and NT-proBNP), yielding a probability score ranging from 0 to 1 (or 0% to 100% when multiplied by 100). Higher scores indicate a higher probability of 30-day mortality, i.e., a worse outcome.

    Measured: 18 ± 4 hours, 42 ± 6 hours, and 66 ± 8 hours after randomization

  6. C-reactive protein (CRP) concentration

    Serum CRP concentrations measured before and after CRP apheresis sessions.

    Measured: 9 ± 1 hours, 34 ± 4 hours, 58 ± 6 hours, and 66 ± 8 hours after randomization

  7. Peak NT-proBNP concentration

    Maximum NT-proBNP serum concentration recorded during the index hospital stay.

    Measured: During index hospitalization

  8. Peak serum creatinine concentration

    Maximum serum creatinine concentration recorded during the index hospital stay.

    Measured: During index hospitalization

  9. Cardiac power index

    The Cardiac Power Index (CPI) is a continuous hemodynamic measurement reflecting the rate of cardiac energy output indexed to body surface area, calculated as cardiac index × mean arterial pressure × a constant (W/m²). It is not a score on a defined scale but a continuous physiological parameter without fixed minimum or maximum values. Normal values are generally reported in the range of 0.5-0.7 W/m². Lower CPI values are associated with worse outcomes, including higher mortality, need for cardiac transplantation, or ventricular assist device placement - thus, higher values indicate better cardiac performance.

    Measured: 18 ± 4 hours, 42 ± 6 hours, and 66 ± 8 hours after randomization

  10. Time to hemodynamic stabilization

    Time from randomization to sustained hemodynamic stabilization as defined by the treating physician.

    Measured: hospital discharge

  11. Duration of catecholamine therapy

    Total duration of vasopressor and inotropic support.

    Measured: hospital discharge

  12. Length of intensive care unit stay

    Number of days spent in the intensive care unit.

    Measured: hospital discharge

  13. Length of hospital stay

    Total length of hospital stay in days.

    Measured: hospital discharge
