BURLINGTON, Mass., August 9, 2022 (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 financial results for the second quarter ended June 30, 2022 and provided a business update.

Business Update

• Announced U.S. Food and Drug Administration (FDA) acceptance of FUROSCIX (furosemide) 80 mg/10 mL for subcutaneous administration New Drug Application (NDA) and Prescription Drug User-Fee Act (PDUFA) target action date of October 8, 2022.

• Continued to advance commercial readiness activities in anticipation of a Q4 2022 commercial launch of FUROSCIX, if approved, including payer research, and completed hiring of all commercial management positions.

• Hosted a virtual investor webinar, FUROSCIX (furosemide) 80 mg/10 mL for subcutaneous administration Commercial Day: An Investigational Treatment for Heart Failure Patients. The webinar featured presentations by Key Opinion Leaders (KOLs) Dr. Daniel Bensimhon and James T. Kenney who discussed, respectively: 1) the unmet clinical need in treating heart failure patients and 2) insights from the payer perspective including the high costs associated with treating these patients.

• Announced positive results from the AT HOME-HF Phase 2 Pilot study. The study results favored FUROSCIX over a “treatment as usual” approach across all pre-defined secondary endpoints. Furthermore, subjects randomized to FUROSCIX had a 37% reduction in the risk of a heart failure hospitalization relative to patients randomized to “treatment as usual” at day 30.

• Announced that two abstracts were accepted for presentation summarizing the positive results from the company’s FREEDOM-HF study at the American Association of Heart Failure Nurses 18th Annual Meeting, which was held June 15-18.

• Ended the second quarter with cash, cash equivalents, restricted cash and investments of $56.0 million.

“The key highlight of the second quarter of 2022 was clearly the FDA’s acceptance of our FUROSCIX NDA and assignment of an October 8^th PDUFA date, and we are continuing to advance our commercial readiness activities in anticipation of a fourth quarter commercial launch, if approved,” stated John Tucker, chief executive officer of scPharmaceuticals. “At the same time, we added to the growing body of evidence demonstrating that there

exists a significant unmet need in the treatment of heart failure patients, a significant source of hospital admissions and readmissions. We believe FUROSCIX, if approved, may represent a new paradigm in the treatment of heart failure with the potential to improve patient outcomes while generating significant cost savings for payers.”    

Second Quarter 2022 Financial Results and Financial Guidance

scPharmaceuticals ended the second quarter of 2022 with $56.0 million in cash, cash equivalents, restricted cash and investments, compared to $75.5 million as of December 31, 2021.

scPharmaceuticals reported a net loss of $9.7 million for the second quarter of 2022, compared to $7.1 million for the comparable period in 2021.

Research and development expenses were $5.1 million for the second quarter of 2022, compared to $3.8 million for the comparable period in 2021. The increase in research and development expenses for the quarter ended June 30, 2022 was primarily due to an increase in pharmaceutical development costs, including supplies, and employee-related costs, offset by a decrease in regulatory consulting costs.

General and administrative expenses were $4.3 million for the second quarter of 2022, compared to $2.6 million for the comparable period in 2021. The increase in general and administrative expenses for the quarter ended June 30, 2022 was primarily attributable to an increase in employee-related costs and commercial preparation costs.

Based on its current operating plan, the Company forecasts its 2022 net loss to be $43 to $48 million.

As of June 30, 2022, scPharmaceuticals total shares outstanding was 27,395,146.
