SteadyMed Receives Refusal to File Letter from FDA for Trevyent® New Drug Application

SAN RAMON, Calif., Aug. 31, 2017 -- SteadyMed Ltd. (Nasdaq:STDY), a specialty pharmaceutical company focused on the development of drug product candidates to treat orphan and high-value diseases with unmet parenteral delivery needs, today announced receipt of a Refusal to File letter from the U.S. Food and Drug Administration (FDA) relating to its New Drug Application (NDA) for Trevyent^® for the treatment of Pulmonary Arterial Hypertension (PAH).

Based on a preliminary review of the NDA, which was submitted in June 2017, the FDA determined that the application is not sufficiently complete to permit a substantive review. FDA has requested further information on certain device specifications and performance testing and has requested additional design verification and validation testing on the final, to-be-marketed Trevyent product. Within the next 30 days, the Company will request a Type A meeting with the FDA to gain further clarification on the additional information required for resubmission and acceptance of the NDA. The Company will provide further guidance after the anticipated meeting with FDA.

“We believe that the issues raised in the letter from FDA can be sufficiently addressed. Our next step is to work with the FDA to address the open issues and identify a path to a successful resubmission and acceptance of our application,” said Jonathan M. N. Rigby, President and CEO of SteadyMed. “We believe that Trevyent holds the potential to significantly improve the lives of patients suffering from PAH compared to the current standard of care, and remain committed to bringing the product to patients in need.”

Designed to address the limitations of existing PAH therapies, SteadyMed’s investigational drug product Trevyent, combines its preservative-free, parenteral treprostinil formulation with the Company’s proprietary PatchPump^®, in a sterile, pre-filled, pre-programmed, single use disposable infusion system capable of delivering treprostinil subcutaneously or intravenously.
