scPharmaceuticals Announces FDA Approval of Supplemental New Drug Application Expanding the FUROSCIX Indication in Heart Failure

FUROSCIX is now indicated for the treatment of congestion due to fluid overload in adult patients with chronic heart failure, regardless of New York Heart Association (NYHA) functional class

Indication expansion allows for the use of FUROSCIX in NYHA Class IV chronic heart failure patients

BURLINGTON, Mass., Aug. 12, 2024 (GLOBE NEWSWIRE) -- scPharmaceuticals Inc. (Nasdaq: SCPH) (the “Company”), a pharmaceutical company focused on developing and commercializing products that have the potential to optimize the delivery of infused therapies, advance patient care, and reduce healthcare costs, today announced that the Food and Drug Administration (FDA) has approved its Supplemental New Drug Application (sNDA) seeking to expand the FUROSCIX indication for heart failure patients. At approval, FUROSCIX was only indicated for the treatment of congestion due to fluid overload in adult patients with New York Heart Association (NYHA) Class II and Class III chronic heart failure. The new indication now includes patients with NYHA Class IV chronic heart failure who represent the most symptomatic patients and those with the greatest limitation on physical activity, comprising approximately 10% of all heart failure patients nationally.

“FDA approval of our sNDA represents a natural expansion of the FUROSCIX indication given its established efficacy and safety in treating congestion due to fluid overload in adult patients with chronic heart failure, offering the potential to prevent the need for heart failure-related hospital admission or readmission,” stated John Tucker, Chief Executive Officer of scPharmaceuticals. “The growing adoption of FUROSCIX among cardiologists and heart failure specialists, together with our other FUROSCIX life cycle management initiatives, has created a solid foundation from which we plan to drive sustained long-term growth.”

FUROSCIX® (furosemide injection) 80 mg/10mL for subcutaneous use

FUROSCIX® is indicated for the treatment of congestion due to fluid overload in adult patients with chronic heart failure.

IMPORTANT SAFETY INFORMATION

FUROSCIX is contraindicated in patients with anuria, patients with a history of hypersensitivity to furosemide, any component of the FUROSCIX formulation or medical adhesives and in patients with hepatic cirrhosis.

Furosemide may cause fluid, electrolyte, and metabolic abnormalities, particularly in patients receiving higher doses, patients with inadequate oral electrolyte intake, and in elderly patients. Serum electrolytes, CO2, BUN, creatinine, glucose, and uric acid should be monitored frequently during furosemide therapy.

Excessive diuresis may cause dehydration and blood volume reduction with circulatory collapse and possibly vascular thrombosis and embolism, particularly in elderly patients.

Furosemide can cause dehydration and azotemia. If increasing azotemia and oliguria occur during treatment of severe progressive renal disease, discontinue furosemide.

Cases of tinnitus and reversible or irreversible hearing impairment and deafness have been reported with furosemide. Reports usually indicate that furosemide ototoxicity is associated with rapid injection, severe renal impairment, the use of higher than recommended doses, hypoproteinemia or concomitant therapy with aminoglycoside antibiotics, ethacrynic acid, or other ototoxic drugs.

In patients with severe symptoms of urinary retention (because of bladder emptying disorders, prostatic hyperplasia, urethral narrowing), the administration of furosemide can cause acute urinary retention related to increased production and retention of urine. These patients require careful monitoring, especially during the initial stages of treatment.

Contact with water or other fluids and certain patient movements during treatment may cause the On-body Infusor to prematurely terminate infusion. Ensure patients can detect and respond to alarms.

The most common adverse reactions with FUROSCIX administration in clinical trials were site and skin reactions including erythema, bruising, edema, and injection site pain.
