BURLINGTON, Mass., May 8, 2019 (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 first quarter ended March 31, 2019 and provided a business update.

“We enter 2019 with good momentum and an increasingly clear line of sight on what we need to accomplish to refile our NDA for FUROSCIX in 2020,” said John Tucker, president and chief executive officer of scPharmaceuticals. “We look forward to working with the FDA in June to solidify refiling requirements. In the interim, we anticipate initiating our first human factors study using our next generation delivery device, the West Pharmaceutical Services, Inc. (West) SmartDose® drug delivery system with FUROSCIX. In addition, we continue to advance new development work with furosemide, the active drug in FUROSCIX, and have filed additional formulation patents for FUROSCIX, with patent protection extending to 2040. With a strong balance sheet to support the work required to refile the NDA for FUROSCIX, we remain committed to our focus of transforming the treatment of heart failure to improve patient care, reduce hospitalizations, and lessen healthcare costs.”

Business Highlights

• Regulatory update on FUROSCIX.The Company submitted a meeting package to the FDA and has scheduled a Type C Meeting that will take place in June 2019. This Type C Meeting will be the first meeting the Company has had with the FDA since the Company elected to expedite the advancement of a next-generation infusor, which includes apre-filled cartridge and other device features expected to address prior FDA requirements. The Company believes the upcoming meeting with the FDA will solidify plans for the refiling of FUROSCIX in 2020. FUROSCIX is scPharmaceuticals’ lead product being developed for the treatment of congestion, or fluid overload, in patients with heart failure.

• The Company plans to initiate and complete first human factors study in the second quarter of 2019. On January 29, 2019, the Company signed a development agreement with West to incorporate West’s SmartDose drug delivery system with the Company’s subcutaneous formulation of furosemide, as the FUROSCIX Infusor. As part of the transition to the SmartDose system, the Company is required to conduct a series of human factors studies under the current 505(b)(2) approval pathway for FUROSCIX. The human factors studies are designed to evaluate FUROSCIX’s use in a real world setting to determine if the product is being used correctly and

safely by the intended users of the product. The Company plans to include the outcome of the human factors studies in the NDA resubmission.

• Filed provisional patent of FUROSCIX that could extend protection through 2040. The Company recently filed a provisional composition of matter patent on a liquid pharmaceutical formulation containing an increased concentration of furosemide. Additional method patents were filed on ways of treating congestion, fluid overload, or hypertension using these formulations of furosemide. Development work around a new, increased concentration of furosemide in FUROSCIX offers the potential to enable greater dosing flexibility.
