SteadyMed Announces Public Availability of PTAB Decision to Institute Inter Partes Review Proceedings

SAN RAMON, Calif., April 25, 2016 (GLOBE NEWSWIRE) -- 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 that the Decision to Institute the Inter Partes Review (IPR) proceeding against U.S. Patent No. 8,497,393 (the '393 patent), owned by United Therapeutics (Nasdaq:UTHR), is now publicly available. This patent relates to a process to further purify prostacyclin derivatives, such as treprostinil. Treprostinil is the active pharmaceutical ingredient used in United Therapeutics' Remodulin® and SteadyMed's lead drug candidate, Trevyent®, for the treatment of Pulmonary Arterial Hypertension (PAH).

The Institution Decision can now be found on the web site,, of the Patent Trial and Appeal Board (PTAB) of the United States Patent and Trademark Office (USPTO) under the case number IPR2016-00006, Document No. 17.

This redacted Institution Decision states that PTAB has "reviewed SteadyMed’s evidence, arguments, and claim charts” and concluded that “for the foregoing reasons we determine that the information presented in the Petition establishes that there is a reasonable likelihood that SteadyMed would prevail in challenging claims 1–22 of the ’393 patent”. Claims 1-22 constitute all the claims of the ‘393 patent.

“We are pleased that the details of PTAB’s institution of the IPR, as well as their conclusions, are now publicly available and we are optimistic of a favorable conclusion,” said Jonathan Rigby, President & CEO of SteadyMed. “We look forward to submitting our New Drug Application (NDA) for Trevyent later this year. If approved, we believe Trevyent will be a very meaningful drug product for patients struggling with PAH.”

On 20 April, SteadyMed hosted an Analyst and Investor reception, where Fernando Torres, M.D., Professor of Medicine at UT Southwestern Medical Center and Director of the Lung Transplant and Pulmonary Hypertension Programs at Clements University Hospital provided an insightful presentation on PAH and the therapies used to treat it. Jonathan Rigby provided a corporate overview of SteadyMed and discussed the IPR. An audio webcast and copies of the presentations can be found on the Investor Relations page of
