RenalGuard Solutions™, Inc., a medical device company focused on innovative fluid management technologies for the cardiac and vascular markets, today announced new clinical study results demonstrating the feasibility of using RenalGuard®-Guided Diuretic Therapy to optimize fluid management in Acute Decompensated Heart Failure (ADHF) patients while alleviating related symptoms. Study results were presented today during a late-breaking presentation at the European Society of Cardiology Heart Failure 2018 conference in Vienna.
“We are thrilled to reveal late-breaking data that demonstrates a promising step towards a new therapy for patients suffering from Acute Decompensated Heart Failure,” says Jim Dillon, CEO of RenalGuard Solutions. “RenalGuard-Guided Diuretic Therapy has the potential to establish a new front-line standard of care for heart failure patients, allowing physicians to maximize fluid removal while protecting patients from the potential negative impact of excessive fluid loss.”
ADHF is a sudden onset of heart failure symptoms, which typically include difficulty breathing (dyspnea), swelling in the extremities and fatigue. Current treatment for ADHF includes diuretic therapy that aims to restore healthy fluid levels in the kidneys and throughout the body. Diuretic therapy can be unpredictable and lose effectiveness as a patient’s condition worsens. In some patients, diuretics can trigger a condition called “diuretic resistance,” which blunts the function of diuretics and can worsen the severity of fluid overload, potentially resulting in acute kidney injury. RenalGuard-Guided Diuretic Therapy is designed to allow clinicians to increase the dose of diuretics without increasing the risk of diuretic resistance, enabling safe and effective removal of excess fluid from ADHF patients and alleviation of symptoms.
This first-in-human clinical trial evaluated nine patients hospitalized for ADHF. Patients underwent 24 hours of standard diuretic therapy with intravenous furosemide, followed by 24 hours of diuretics in conjunction with RenalGuard-Guided Diuretic Therapy. Results demonstrated that clinicians were able to achieve a safe rate of fluid loss by inducing high urine rates and maintaining intravascular volume using the treatment.
Study results showed a significant improvement in breathing patterns and diuretic efficiency among patients treated with RenalGuard-Guided Diuretic Therapy, creating a more than two-and-a-half-fold increase in the amount of urine they produced. Average urine output measured over 24 hours of standard diuretic therapy was 1,961 mL. Over the next 24 hours, RenalGuard-Guided Diuretic Therapy was applied in conjunction with diuretic therapy, and average urine output increased to 4,771 mL (p<0.01). The average change in estimated kidney function at 30 days after the trial, measured using the glomerular filtration rate, showed an average increase of 8%, with three patients demonstrating an increase of more than 25%.
