BURLINGTON, Mass., March 22, 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 fourth quarter and full year ended December 31, 2021 and provided a business update.

Business Update

• The Company has completed, and is pleased with the results of, all testing of the West Pharmaceutical Services on-body infusor manufactured on the planned commercial line, as required by the U.S. Food and Drug Administration (FDA).

• The Company recently elected to change packaging vendors, which necessitated minor modifications to its FUROSCIX New Drug Application (NDA). As a result, the Company anticipates resubmitting it’s NDA by April 15^th 2022. The Company is on track for a Q4 2022 commercial launch, if approved.

• The Company continues to advance its commercial readiness activities, including:

• Finalizing physician, payer and pricing research;

• Communicating FUROSCIX data, including FREEDOM-HF to pharmacy benefit managers and health plans through its product dossier;

• Finalizing FUROSCIX distribution partners; and

• Reinitiating commercial staffing to support anticipated Q4 2022 launch.

• The Company presented key secondary endpoint data from the Company’s FREEDOM-HF study at the Cardiovascular Research Foundation Technology and Heart Failure Therapeutics Conference, which was held February 1 – 2, 2022. Highlights include:

• Patients who received FUROSCIX had a median reduction of heart failure peptide biomarkers from study entry (day 0) to first visit (day 2 – 4) and to last visit (day 30) of 42.3% and 28%, respectively (p < 0.01).

• Patients who received FUROSCIX had a 12.8-point improvement in the Kansas City Cardiomyopathy Questionnaire (KCCQ-12) Summary Score, a measure of health-related quality of life, 30 days after study entry (p<0.05).

• Ended the fourth quarter with cash, cash equivalents, restricted cash and investments of $75.5 million.

“We are very pleased with the progress made in 2021, particularly with respect to addressing items raised in the Complete Response Letter that we received from the FDA in late 2020,” stated John Tucker, chief executive officer of scPharmaceuticals. “With the completion of the additional device testing, which met all of our expectations, and the recent change to an alternate packaging vendor, we are on track to resubmit the FUROSCIX NDA in the first half of April and continue with our focused preparation for a potential commercial launch of FUROSCIX later this year.

“We believe that FUROSCIX, if approved, represents an important new option in the treatment of congestion related to heart failure. Further, the results of our FREEDOM-HF study offer compelling pharmacoeconomic and quality of life data. We believe we are well-funded and are optimistic that we will introduce this promising new therapy to the benefit of patients, payers and providers with the potential to generate significant health system cost savings.”

scPharmaceuticals ended the fourth quarter 2021 with $75.5 million in cash, cash equivalents, restricted cash and investments, compared to $105.3 million as of December 31, 2020.

scPharmaceuticals reported a net loss of $7.3 million for the fourth quarter of 2021, compared to $7.8 million for the comparable period in 2020.

The increase in research and development expenses for the quarter ended December 31, 2021 was primarily due to an increase in clinical study activity, employee-related costs and quality and regulatory consulting, offset by a decrease in device and pharmaceutical development costs.

General and administrative expenses were $2.2 million for the fourth quarter of 2021, compared to $3.4 million for the comparable period in 2020. The decrease in general and administrative expenses for the quarter ended December 31, 2021 was primarily due to a decrease in legal costs and costs related to commercial preparations.

The decrease in research and development expenses for the year ended December 31, 2021 was primarily due to a decrease in device and pharmaceutical development activities, offset by clinical study activity and employee-related costs.

General and administrative expenses were $9.8 million for the year ended December 31, 2021, compared to $11.8 million for the comparable period in 2020. The decrease was primarily due to employee-related and professional service costs, including legal costs and costs related to commercial preparations. This decrease was offset by increases in public company costs, including costs related to directors and officers insurance.

Based on its current operating plan, the Company forecasts its 2022 net loss to be $43 to $48 million. As of December 31, 2021, scPharmaceuticals total shares outstanding was 27,366,707.
