On August 23, 2017, scPharmaceuticals Inc. (the “Company”) submitted to the U.S. Food and Drug Administration (the “FDA”) a New Drug Application (the “NDA”) under section 505(b)(2) of the Federal Food, Drug, and Cosmetic Act for Furoscix™ Infusor (furosemide), 80 mg/10 mL, drug-device combination product. Under the Prescription Drug User Fee Act (“PDUFA”), the FDA had set June 23, 2018 as a target date for a decision on the NDA. On May 30, 2018, the Company received a notification from the FDA (the “Notification”) stating that, as part of its ongoing review of the Company’s NDA, the FDA has identified deficiencies that preclude discussion of labeling and postmarketing requirements/commitments at this time. The FDA stated that the Notification does not reflect a final decision on the information under review.

The Notification does not specify the deficiencies identified by the FDA. The Company plans to work with the FDA to understand the nature of the deficiencies once identified and resolve them as quickly as possible.

On May 31, 2018, the Company issued a press release announcing its receipt of the Notification. A copy of Company’s press release is filed herewith as Exhibit 99.1 and is incorporated into this Item 8.01 by reference.

By filing this information, the Company makes no admission as to the materiality of any information in this report. The information contained in this report is intended to be considered in the context of the Company’s filings with the U.S. Securities and Exchange Commission (the “Commission”) and other public announcements that the Company makes, by press release or otherwise, from time to time. The Company undertakes no duty or obligation to publicly update or revise the information contained in this report, although it may do so from time to time as its management believes is appropriate. Any such updating may be made through the filing of other reports or documents with the Commission, through press releases or through other public disclosure.

This report contains forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995 and other federal securities laws. Any statements contained herein which do not describe historical facts, including but not limited to statements regarding the timing of the FDA’s approval of the NDA, the Company’s expectations with regard to its discussions with the FDA, plans, and expectations as to the PDUFA date are forward-looking statements which involve risks and uncertainties that could cause actual results to differ materially from those discussed in such forward-looking statements. Such risks and uncertainties include, without limitation, any deficiencies the FDA may identify with respect to Furoscix and whether the Company will be able to address the issues that may relate to those deficiencies, the receipt of regulatory approval for Furoscix and the Company’s other product candidates, the Company’s ability to market and sell its product candidates, if approved, the Company’s ability to successfully compete in the market for treatment of heart failure, the Company’s ability to manufacture Furoscix or any of its other product candidates, and other risks set forth under the caption “Risk Factors” in the Company’s Annual Report on Form 10-K for the year ended December 31, 2017 and its subsequent public filings with the Commission. The Company cautions you not to place undue reliance on any forward-looking statements, which speak only as of the date they are made. Except as required by law, the Company disclaims any obligation to publicly update or revise any such statements to reflect any change in expectations or in events, conditions or circumstances on which any such statements may be based, or that may affect the likelihood that actual results will differ from those set forth in the forward-looking statements.
