(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 preliminary unaudited fourth quarter 2023 net FUROSCIX revenue in a range of $5.9 million to $6.1 million, representing sequential growth of 55% to 61% over $3.8 million net FUROSCIX revenue reported for the third quarter of 2023. For the full year 2023, the Company anticipates net revenue to be in a range of $13.4 million to $13.6 million. The gross-to-net discount decreased to approximately 18% from launch through the end of Q4 versus 21% from launch through the end of Q3. The Company anticipates the gross-to-net discount to increase as FUROSCIX is added to more payer formularies. Inventory levels at the end of Q4 2023 were consistent with levels at the end of Q3 2023. “We are very pleased with the continued traction that FUROSCIX is gaining among heart failure prescribers as reflected in the preliminary fourth quarter and full year net FUROSIX revenue that we are announcing today,” stated John Tucker, Chief Executive Officer of scPharmaceuticals. “We believe this positive trend speaks to the significant value that FUROSCIX delivers to payers, physicians and patients.” scPharmaceuticals also announced today that unaudited cash, cash equivalents and short-term investments were approximately $76 million as of December 31, 2023. These preliminary select financial results are unaudited and subject to change. scPharmaceuticals will report its final and complete fourth quarter and full-year 2023 financial results in March. The Company has not completed its financial closing procedures for the quarter or year ended December 31, 2023 and its actual results could be materially different from these preliminary financial results. 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.
