If successful, scPharmaceuticals plans to submit a New Drug Application (NDA) to the FDA by the end of 2024.Advanced plans to submit an sNDA to the FDA next month seeking expansion of the FUROSCIX indication to include patients suffering from chronic kidney disease (CKD).Announced that the Company’s sNDA submission to the FDA seeking to expand the FUROSCIX indication to include New York Heart Association Class IV heart failure patients is currently under review by the FDA.Ended the fourth quarter of 2023 with cash, cash equivalents and short-term investments of $76.0 million. “We ended 2023 on a strong note, generating net FUROSCIX sequential revenue growth of 61%, which we believe reflects growing awareness and acceptance of FUROSCIX as a key component of a new heart failure treatment paradigm,” stated John Tucker, President, and Chief Executive Officer of scPharmaceuticals. “Our reported gross-to-net discount of 18% declined from launch through the end of Q4 as compared to 21% from launch through the end of Q3. However, we continue to anticipate that the GTN discount will increase over time as our contracting efforts continue to evolve and mature.” “Also, during the fourth quarter, we continued to advance the life cycle management and long-term growth initiatives for FUROSCIX that we previewed last quarter. These include the potential expansion of the FUROSCIX indication to include NYHA Class IV heart failure patients, which is currently under review by FDA, an additional indication in chronic kidney disease, for which we plan to file with the FDA next month , and the development of an auto-injector that would complement the current on-body infusor, a PK study for which we plan to initiate in the next few weeks. We continue to advance these initiatives while at the same time successfully driving uptake of FUROSCIX, and both our fourth quarter results and leading indicators confirm that FUROSCIX acceptance and utilization among heart failure specialists is accelerating,” Mr. Tucker concluded.

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.

In its feedback, the agency confirmed that no additional clinical study is required and only an adequate PK and pharmacodynamic bridge to the listed drug, furosemide injection, 10 mg/mL, would be required for the expansion.Received favorable meeting feedback from the FDA regarding the potential expansion of the FUROSCIX indication to include New York Heart Association (NYHA) Class IV heart failure patients.

To that end, we added 12 sales territories during the third quarter, ending the quarter with 66.” “We continued to have productive discussions with payers. Last quarter, we announced that we had secured national Medicaid coverage effective July 1. Also, in late October, we reached an agreement with one of the largest closed integrated delivery networks in the United States, providing unrestricted access to FUROSCIX, without prior authorization, to over eight million lives at a fixed copay of $75 or less per prescription. We are advancing late-stage discussions with additional national and regional payers and will provide further updates as appropriate.” “In parallel, we made significant progress during the quarter and subsequent period advancing life cycle management initiatives for FUROSCIX that could help drive our longer-term growth. These include the potential expansion of the FUROSCIX indication to include NYHA Class IV heart failure patients, additional indications such as chronic kidney disease, and the introduction of greater dosing flexibility through the development of an auto-injector that would complement the current on-body infusor. We are advancing these initiatives while at the same time remaining acutely focused on driving continued uptake of FUROSCIX since its commercial launch in February,” Mr. Tucker concluded.
