scPharmaceuticals Announces Positive Feedback from Two FDA Meetings on Key Long-Term Growth Initiatives

Company advancing plans to expand the FUROSCIX franchise to include an 80mg/1ml auto-injector as an additional delivery system designed to provide greater flexibility to heart failure patients

Agency confirms no additional clinical data required to pursue label expansion of FUROSCIX into chronic kidney disease (CKD)

BURLINGTON, Mass., Sept. 19, 2023 (GLOBE NEWSWIRE) -- scPharmaceuticals Inc. (Nasdaq: SCPH), 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 Company has received positive feedback from the U.S. Food and Drug Administration (FDA) on two key long-term growth initiatives.

The Company today announced FDA feedback from a Type C meeting pertaining to the development of an 80mg/1mL auto-injector intended to provide an additional option to the on-body infusor for treatment of congestion due to fluid overload in eligible adult patients who do not require hospitalization.

The Company expects that an auto-injector, if successfully developed and approved, would reduce manufacturing costs compared to the current on-body infusor and confer environmental advantages. scPharmaceuticals plans to report data from a pivotal pharmacokinetic (PK) study in first half of 2024, and, if successful, targets submitting a Supplemental New Drug Application (sNDA) to the FDA by the end of 2024.

The Company also announced today feedback from a Type D meeting with the FDA pertaining to the potential expansion of the FUROSCIX label to include treatment of edema due to fluid overload in patients with CKD. In its feedback, the FDA confirmed that no additional clinical studies are needed to expand the indication, provided that the Company demonstrates an adequate PK and pharmacodynamic bridge to the listed drug, furosemide injection, 10 mg/mL. CKD is a progressive disease characterized by worsening renal function over time, resulting in frequent episodes of fluid overload that are treated with loop diuretics.

“We are very pleased to have reached alignment with the FDA on the advancement of these two very important long-term growth initiatives for our company,” stated John Tucker, Chief Executive Officer of scPharmaceuticals. “We believe the development of an auto-injector, designed to administer a subcutaneous injection of our proprietary, concentrated furosemide formulation, represents a new potential treatment alternative that could further increase the appeal of FUROSCIX among both treating physicians and their patients while significantly lowering our costs. We look forward to announcing pivotal PK data and submitting a sNDA next year.”

“It is estimated that 12-15 million Americans are aware that they have kidney disease and 50% of patients with CKD do not have a diagnosis of heart failure. With fluid overload being one of the most common complications in CKD, which worsens with disease progression, we believe FUROSCIX could be beneficial to patients with CKD who have worsening symptoms due to fluid overload and are not responding to oral loop diuretics. We plan to advance FUROSCIX as we work towards our goal of introducing a new treatment option to CKD patients with edema as efficiently as possible.”

In August, scPharmaceuticals announced the issuance of U.S. patents covering concentrated formulations of furosemide. The Company has completed initial solubility and stability studies on multiple formulations described in the patent properties, has identified potential product candidates, and commenced Investigational New Drug Application enabling studies. scPharmaceuticals has additional U.S. patent applications pending that cover various methods of use of such or similar formulations of furosemide for treatment of congestion in patients with heart failure and edema in patients with kidney disease. The Company is also pursuing similar patent protection outside of the United States.

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 New York Heart Association (NYHA) Class II and Class III chronic heart failure.

FUROSCIX is not indicated for use in emergency situations or in patients with acute pulmonary edema. The On-Body Infusor will deliver only an 80-mg dose of FUROSCIX.

IMPORTANT SAFETY INFORMATION

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

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.

In patients with hepatic cirrhosis and ascites, sudden alterations of fluid and electrolyte balance may precipitate hepatic encephalopathy and coma. Treatment in such patients is best initiated in the hospital.

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

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.

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