Using PolyCore for fluid removal in heart failure patients

Peritoneal Ultrafiltration in Cardio Renal Syndrome to Prevent Heart Failure Exacerbation.

Phase1; Phase2 Interventional Iperboreal Pharma Srl · NCT03994874

This study is testing if a new treatment called PolyCore can help heart failure patients who still have symptoms feel better when added to their usual medications.

What this trial studies

This clinical trial evaluates the safety and efficacy of PolyCore (a combination of Polydextrin, L-Carnitine, and D-xylitol) for peritoneal ultrafiltration in adults with heart failure and reduced ejection fraction (HFrEF) who continue to experience symptoms despite standard medical therapy. Participants will be randomly assigned to receive either PolyCore treatment or continue with their prescribed heart failure medications alone for a duration of six months. The study includes an independent data safety monitoring board to ensure patient safety and will conduct interim analyses to adjust the sample size as needed based on early results. The goal is to determine if PolyCore can improve outcomes for these patients.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 and older with HFrEF and NYHA Class III-IV symptoms despite optimal medical therapy.

Not a fit: Patients with preserved ejection fraction or those who do not meet the specific inclusion criteria will likely not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could provide a new therapeutic option for patients with heart failure who are resistant to standard treatments.

How similar studies have performed: While similar approaches have been explored, this specific combination of PolyCore for peritoneal ultrafiltration in HFrEF patients is relatively novel.

Inclusion Criteria:

* Age ≥18 yrs
* Left ventricular ejection fraction ≤60%
* NYHA Classification of III-IV despite guidelines directed medical therapy
* Right ventricular failure due to after load mismatch, addressed by the presence of tricuspid calve regurgitation (≥ moderate) and by the disproportioned increase of the right atrial pressure (RAP) versus the capillary wedge pressure (CWP) with a ratio ≥0.65, detected with right heart catheterization performed after stable medical therapy according to international guidelines and comprehensive of loop diuretic (equivalent to furosemide oral dose till 2.0 mg/kg/day), coupled with urinary sodium excretion ≤ mEq/L, confirmatory of loop diuretic resistance.
* Cava vein enlargement (inner diameter, detected with focused echocardiography, between 1,5 and 2,5 cm, with respiratory collapse \<50% or absent due to intravascular fluid overload)
