BURLINGTON, Mass., August 11, 2021 (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, 2021 and provided a business update.

Business Update

•

Completed Type C meeting with the U.S. Food and Drug Administration (FDA) and received minutes that confirm alignment on the path toward resubmission of the FUROSCIX New Drug Application (NDA).

o

No additional clinical data or device modifications required at this time.

o

Subject to West Pharmaceutical Services' completion of its portion of the regulatory filing, the Company is targeting the resubmission of its NDA in the fourth quarter of this year and anticipates a six-month review by the FDA.

•

Announced positive top-line results from the FREEDOM-HF study demonstrating that average 30-day heart failure-related costs were reduced by $17,753 per study subject in the FUROSCIX arm compared to historically matched comparators, with a very high level of statistical significance (p<0.0001).

o

Due to the highly statistically significant reduction in 30-day heart failure-related costs observed during the prespecified interim analysis, the decision was made to close enrollment earlier than anticipated.

o

The difference in costs was driven primarily by hospitalization costs. Per protocol, all subjects (24/24) who received FUROSCIX did not require an initial heart failure hospitalization, and all but one (95.8%) remained out of the hospital for heart failure for the subsequent 30-day period.

•

FREEDOM-HF data has been accepted as a Late Breaking Clinical Trial for presentation at the upcoming Heart Failure Society of America (HFSA) Annual Scientific Meeting being held September 10 through September 13, 2021 both in Denver, Colorado and virtually.

•

Continued to enroll the AT HOME-HF PILOT study evaluating the effectiveness and safety of FUROSCIX versus continued medical therapy in patients with chronic heart failure and fluid overload requiring augmentation in diuretic therapy outside of the hospital.

•

Ended the second quarter with cash, cash equivalents, restricted cash and investments of $90.2 million.

'During the second quarter and subsequent period, we made significant progress, gaining alignment with the FDA on the path toward our FUROSCIX NDA resubmission, which we are targeting for Q4' stated John Tucker, chief executive officer of scPharmaceuticals. 'Importantly, the FDA is not requiring additional clinical data or modifications to the on-body infusor at this time, and we are working tirelessly to complete the additional bench testing that has been requested. If our NDA is accepted, we anticipate a six-month review, suggesting that FUROSCIX, if approved, could be available to heart failure patients in the second half of next year.

'To further support a potential commercial launch, we were extremely pleased with the top-line results from our FREEDOM-HF study which demonstrated that patients treated with FUROSCIX cost healthcare payers nearly $18,000 less over a 30-day span as compared to historically matched comparators. Given the prevalence of worsening heart failure, and the potential addressable market of 2.1 million heart failure events in the United States, this pharmacoeconomic benefit is significant and should aid in adoption of FUROSCIX, if approved.

'We ended the quarter in a strong cash position, which we believe is sufficient to fund operations through a potential launch and into 2023. We look forward to introducing this novel therapy, if approved, to the many heart failure patients who can benefit,' Mr. Tucker concluded.

Second Quarter 2021 Financial Results and Financial Guidance

scPharmaceuticals ended the second quarter with $90.2 million in cash, cash equivalents, restricted cash and investments, compared to $105.3 million as of December 31, 2020, The Company believes its cash, cash equivalents, restricted cash and investments are sufficient to fund operations into 2023.

scPharmaceuticals reported a net loss of $7.1 million for the second quarter of 2021, compared to $8.3 million for the comparable period in 2020.

Research and development expenses were $3.8 million for the second quarter of 2021, compared to $5.1 million for the comparable period in 2020. The decrease in research and development expenses for the quarter ended June 30, 2021 was primarily due to a decrease in device development costs, offset by an increase in costs related to pharmaceutical development and medical affairs, as well as an increase in employee-related costs.

General and administrative expenses were $2.6 million for the second quarter of 2021, compared to $2.5 million for the comparable period in 2020. The increase in general and administrative costs for the quarter ended June 30, 2021 was primarily attributable to an increase in consulting and director and officer's insurance costs, offset by a decrease in legal costs.

Based on its current operating plan, the Company expects its net loss for 2021 to be in the range of $30.0 to $34.0 million for the fiscal year, a decrease over prior guidance of $32.0 to $36.0 million.
