SteadyMed Reports Second Quarter 2017 Financial Results and Provides Corporate Update

Submitted New Drug Application for Trevyent for the Treatment of Pulmonary Arterial Hypertension

On track for Mid-2018 U.S. Commercial Launch, Subject to FDA Approval

SAN RAMON, Calif., August 11, 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 provided a corporate update and reported financial results for the second quarter ended June 30, 2017.

Second Quarter 2017 and Recent Corporate Highlights Include:

·                  In June, SteadyMed submitted its New Drug Application (NDA) to the Food and Drug Administration (FDA) for Trevyent® for the treatment of Pulmonary Arterial Hypertension (PAH). Designed to address the limitations of existing PAH therapies, Trevyent combines SteadyMed’s 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.

·                  In April, SteadyMed was successful in raising additional capital with $28.1 million in net proceeds in a private placement led by institutional healthcare investors Adage Capital, OrbiMed, Deerfield Management and Kingdon Capital Management.  This additional capital is expected to fund pre- and post- launch commercial activities, distribution network establishment and manufacture of commercial Trevyent inventory aimed at a mid-2018 commercial launch in the U.S., subject to NDA approval, as well as working capital and general corporate purposes.

·                  In May, SteadyMed raised an additional $4.8 million in capital when a large institutional shareholder exercised its warrants to purchase additional ordinary shares of the Company.

·                  In July, SteadyMed appointed Jeff Myers, M.D., Ph.D. as Vice President, Medical Affairs. Dr. Myers, who joined the Company from Gilead Sciences, brings significant experience in the cardio-pulmonary space, including direct experience with PAH products. At SteadyMed, he will be responsible for scientific and medical affairs in support of Trevyent.

“SteadyMed has had a very successful year to date, culminating in the June, 30, 2017 submission of an NDA for our lead drug candidate, Trevyent. PAH is a serious, life threatening disease, and currently, the administration of high dose prostacyclins to help these patients has some serious challenges. Trevyent, has been developed with the aim of addressing these challenges”, said Jonathan Rigby, President and Chief Executive Officer of SteadyMed. “We completed the second quarter with a strong cash position of $43.5 million. We believe this provides the necessary foundation to execute on our next major milestones for the Company through the launch of Trevyent in the U.S., which is anticipated in mid 2018, subject to FDA approval.”

Second Quarter 2017 Financial Results Compared to Second Quarter 2016 Financial Results

SteadyMed recorded licensing revenues of $319 thousand in the second quarter of 2017, compared to $94 thousand in the second quarter of 2016. The increase in recorded revenues was attributable to the adjustment to the estimated performance obligations period in the second quarter of 2016.

For the second quarter of 2017, SteadyMed reported a net loss of $8.1 million, or $0.33 per share, compared to a net loss of $7.2 million, or $0.53 per share for the second quarter of 2016.  The current quarter’s calculation of loss per share is based on 24,335,774 weighted-average shares outstanding, versus 13,585,810 outstanding shares in the prior-year period.

Total operating expenses for the second quarter of 2017 were $5.1 million, compared to $7.2 million for the second quarter of 2016.  The decrease in total operating expenses was primarily attributable to a decrease in Research and Development (R&D) expenses of $1.8 million and a decrease in Sales and Marketing (S&M) expenses of $0.2 million.

R&D expenses for the second quarter of 2017 were $3.5 million, compared to $5.3 million for the second quarter of 2016. The decrease in R&D expenses was primarily due to a decrease of $1.8 million in subcontractors and materials costs.

S&M expenses for the second quarter of 2017 were $0.4 million, compared to $0.6 million for the second quarter of 2016. The decrease was primarily due to a decrease of $0.5 million in consulting fees and costs related to the pre-commercialization plan for Trevyent, offset by $0.2 million increase in salary expenses mainly due to increase in headcount.

General and administrative (G&A) expenses for the second quarter of 2017 and 2016 were $1.2 million.

Financial expenses, net, amounted to $3.2 million during the second quarter of 2017 were mainly due to an increase in the fair value of warrants to purchase Ordinary Shares in the amount $2.8 million and $0.4 million of warrant issuance costs. The fair value of the warrants increased as a result of the increase in the trading price of the Ordinary Shares of the Company on Nasdaq during the second quarter of 2017. Interest income of $0.07 million was offset by interest expense on bank debt, bank fees and foreign currency translation adjustments.  Financial income, net, amounted to $0.014 million during the second quarter of 2016.

As of June 30, 2017, SteadyMed had cash and cash equivalents of $43.5 million.
