Exhibit 99.1

scPharmaceuticals Inc. Receives Complete Response Letter from FDA for FUROSCIX^®

CRL did not identify clinical deficiencies

BURLINGTON, Mass. – December 7, 2020 – 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 it received a Complete Response Letter (“CRL”) from the U.S. Food and Drug Administration (“FDA”) on December 3, 2020 regarding the Company’s New Drug Application (“NDA”) for FUROSCIX^®.

In the CRL, the FDA cited their need to conduct pre-approval inspections at two of the company’s third-party manufacturing facilities that could not be conducted due to travel restrictions. In addition, the FDA raised questions related to testing, labeling, and features of the combination product unrelated to the drug constituent. In addition, the FDA indicated that there were deficiencies at the third-party facility where the Company’s off-the-shelf alcohol swabs are manufactured. scPharmaceuticals will request a Type A meeting with the FDA to discuss the issues described in the CRL and steps required for the resubmission of the NDA for FUROSCIX^®.

scPharmaceuticals ended the third quarter with cash, cash equivalents, restricted cash, and investments of $114.5 million, which the Company estimates is sufficient to fund operations into 2023 at the projected burn rate.

John Tucker, Chief Executive Officer of scPharmaceuticals, stated: “While we are disappointed that these on-site inspections, and other issues raised in the CRL, will not be resolved by our previously granted December 30, 2020 PDUFA date, we are committed to working with our manufacturing partners and responding to the agency’s concerns as expeditiously as possible. We continue to believe that FUROSCIX^® can play a significant role in preventing heart failure hospital admissions and readmissions due to fluid overload by intervening with this novel therapy at home.”
