Item 8.01 Other Events.

On July 13, 2021, scPharmaceuticals Inc. (the “Company”) announced positive top-line results from its FREEDOM-HF study. FREEDOM-HF was a prospective clinical trial evaluating overall and heart failure-related costs of treating congestion in patients with chronic heart failure. Patients were treated with FUROSCIX^®, the Company’s investigational product, post-discharge from the emergency department compared to a historical comparator group that was treated with intravenous furosemide in the inpatient hospital setting. Based on the results from a planned, prespecified interim analysis conducted to confirm the final sample size, and following input from statisticians, principal investigators, payer advisors and Health Economics and Outcomes Research (HEOR) experts, enrollment was stopped on May 17, 2021, prior to the enrollment target of 34 patients. This decision was made due to the highly statistically significant reduction observed in 30-day heart failure-related costs in patients who received FUROSCIX in the interim analysis. The final analysis included 24 subjects treated with FUROSCIX and 66 matched comparators based on seven variables associated with hospitalization. Comparator patients hospitalized for 72 hours or less were identified, and costs were derived from service-level claims utilizing IBM^® MarketScan^® Research Databases which utilizes coding to standardize financial data from fully paid and adjudicated claims.

The mean difference in heart failure-related costs between the two groups was $17,753 per study subject, with a p-value of p<0.0001 (95% CI: -$23,660, -$11,846), favoring the FUROSCIX group. This difference in costs was driven primarily by hospitalization costs. Per protocol, all subjects (24/24) who were enrolled in the study and 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. In the comparator group, 100% of the patients were initially hospitalized and 10.6% had a heart failure-related readmission. As part of the study design, all FUROSCIX patients were required to have at least one heart failure related clinic visit during the study period. In the comparator group, 34.9% of subjects had a heart failure related clinic visit. Since the price for FUROSCIX has not been established, the difference in costs does not include the cost of FUROSCIX.

Additional analyses, including 30-day overall healthcare cost, quality of life as well as patient and caregiver satisfaction, are ongoing and complete data will be submitted for publication or presentation at an upcoming scientific meeting. The most common adverse events with FUROSCIX were infusion site pain, bruising and dizziness and no serious adverse events related to FUROSCIX were observed.

Statements contained under this Item 8.01 regarding matters that are not historical facts are “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995. Because such statements are subject to risks and uncertainties, actual results may differ materially from those expressed or implied by such forward-looking statements. Such statements include, but are not limited to: statements regarding the significance of the results of the FREEDOM-HF clinical trial, the interpretation and analyses of the results from the FREEDOM-HF clinical trial, the planned resubmission of the FUROSCIX NDA, including potential timing of the resubmission and expected timing of the FDA’s review, the potential timing of, and the Company’s expected progress towards, the advancement of the Company’s device verification, research and validation studies, and the Company’s planned efforts to prepare for commercialization of FUROSCIX.

Any forward-looking statements are based on management’s current expectations of future events and are subject to a number of risks and uncertainties that could cause actual results to differ materially and adversely from those set forth in or implied by such forward-looking statements. Risks that contribute to the uncertain nature of the forward-looking statements include, but are not limited to, the risk that results of a clinical study do not necessarily predict final results and that one or more of the clinical outcomes may materially change following more comprehensive reviews of the data, and as more patient data become available, the risk that results of a clinical study are subject to interpretation and additional analyses may be needed and/or may contradict such results, the risk of the ability of the FUROSCIX On-Body Infusor to appropriately deliver therapy, the receipt of regulatory approval for the FUROSCIX On-Body Infusor or any of the Company’s other product candidates or, if approved, the successful commercialization of such products, the risk of cessation or delay of any of the ongoing or planned clinical trials and/or the Company’s development of the Company’s product candidates, the risk that the results of previously conducted studies will not be repeated or observed in ongoing or future studies involving the Company’s product candidates, and the risk that the current COVID-19 pandemic will impact the Company’s device validation, drug stability testing, the timing of the Company’s resubmission of the FUROSCIX NDA and other operations. For a discussion of these and other risks and uncertainties, and other important factors, any of which could cause the Company’s actual results to differ from those contained in the forward-looking statements, see the section entitled “Risk Factors” in the Company’s Annual Report on Form 10-K filed with the United States Securities and Exchange Commission (“SEC”) and quarterly reports on Form 10-Q filed with the SEC, as well as discussions of potential risks, uncertainties, and other important factors in the Company’s other filings with the SEC. All forward-looking statements contained in this Current Report on Form 8-K speak only as of the date on which they were made. The Company undertakes no obligation to update such statements to reflect events that occur or circumstances that exist after the date on which they were made.
