Feasibility of Selective Cytopheretic Device (SCD) for Cardiorenal Syndrome Patients Awaiting LVAD

This study is looking at a treatment called the Selective Cytopheretic Device (SCD) for people with acute on chronic systolic congestive heart failure (a severe type of heart failure) and cardiorenal syndrome (problems with both the heart and kidneys). The SCD treatment will be given for 4 hours a day for up to 6 days. We want to see if this treatment can reduce the need for continuous IV vasopressor support (medication to raise blood pressure), prevent heart attacks, and improve survival up to 6 months after treatment. You might be able to join if you are 18 or older, have signs of inflammation (like high CRP or IL-6), are hospitalized for acute decompensated chronic systolic heart failure, and are a potential candidate for an LVAD (Left Ventricular Assist Device). The study plans to enroll 20 participants.

Study design
This is an interventional study with a planned enrollment of 20 participants. The study is testing the Selective Cytopheretic Device (SCD).
What's involved
You would receive the Selective Cytopheretic Device (SCD) treatment for 4 hours a day for up to 6 consecutive days.
Compensation
Not stated in the trial record.
Follow-up
Your need for vasopressor support will be measured daily. You will be followed for acute myocardial infarction and mortality for up to 6 months after starting SCD treatment.

Eligibility criteria

Inclusion

Central venous pressure/Pulmonary wedge pressure \>0.65
Right ventricular stroke work index \< 300 mmHg \* ml/m2
Pulmonary artery pulsatility index (PAPi) \< 2, 2. Worsening renal failure (WRF), defined for the purposes of this study as -Increase serum creatinine ≥ 0.5 mg/dL from baseline (baseline defined as the lowest known serum creatinine within 90 days of study enrollment) AND
eGFR\*\* ≤ 30 ml/min/1.73 m2 based on serum creatinine at enrollment\*\*\* AND
Cardiorenal syndrome is the most likely explanation for WRF AND
Intolerant or inadequately responsive to standard of care diuretic therapy, defined as persistent signs and/or symptoms of congestion (e.g., peripheral edema, dyspnea, pulmonary rales, neck vein distension) or minimal net volume removal in a 24-hour period despite optimal medical therapy including intravenous diuretic therapy and an estimated need for \>5kg fluid removal.
eGFR calculated using the CKD-EPI Creatinine Equation \*\*\* Recognizing that this is not a steady state creatinine
  • Need for continuous IV vasopressor supportmeasured daily, at or after 4 hours after termination of daily SCD therapy

    Need for continuous IV vasopressor support with \>5 total norepinephrine equivalents and/or \>3 vasopressor agents \>4 hours following termination of daily SCD therapy session to maintain a MAP \>60 mmHg, with norepinephrine equivalents defined as: 1. 1 x epinephrine (ug/kg/min) 2. 001 x dopamine (ug/kg/min) 3. 0.06 x phenylephrine (ug/kg/min) 4. 2.5 x vasopressin (U/min) (Note that use of inotropes (i.e., dobutamine and milrinone) or dopamine at ≤3 mcg/kg/min are not components of this measure.)

  • Acute myocardial infarctionup to 6 months following SCD treatment initiation

    Acute myocardial infarction as evidenced by elevated cardiac enzymes, with electrocardiographic or imaging findings consistent with myocardial damage and confirmed by Cardiology.

  • Mortalityup to 6 months following SCD treatment initiation

    Death

  • Percentage of subjects with reversal of WRF and increase eGFR and PCWup to 6 days after initiation of SCD therapy

    Among patients with WRF, the percentage of subjects with reversal of WRF (≥ 0.5 mg/dL reduction of serum creatinine from level at study entry), and achieving an eGFR \> 30 ml/min/1.73 m2 and PCWP at or below level at study entry at termination of SCD therapy.

  • Percentage of subjects who no longer have severe right ventricular failureup to 6 days after initiation of SCD therapy
