SteadyMed Provides Update on IPR Hearing

SteadyMed Therapeutics 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 an update regarding its ongoing Inter Partes Review (IPR), challenging U.S. Patent No. 8,497,393 (the '393 patent) owned by United Therapeutics before the Patent Trial and Appeal Board (PTAB) of the United States Patent and Trademark Office (USPTO).

The ‘393 patent relates to a product made by a process to purify prostacyclin derivatives, such as treprostinil, the active pharmaceutical ingredient used in United Therapeutics' Remodulin® and SteadyMed's lead drug candidate, Trevyent®. Upon institution of the IPR, in April 2016, the PTAB stated that it had "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. The April 2016 initiation decision can be found on the PTAB web site, https://ptabtrials.uspto.gov, under the case number IPR2016-00006, Document No. 17.

On November 29, 2016, SteadyMed and United Therapeutics attended an oral hearing at the USPTO. Both parties presented their demonstratives and answered questions from the judges in attendance. The demonstratives can be viewed at ptab.uspto.gov by entering 2016-00006 in the AIA Review Number box and downloading exhibits 1029 and 2061. A written transcript of the hearing is expected to be posted to the USPTO website in the coming weeks.

“We remain pleased with the progress of the IPR and remain optimistic of a favorable conclusion,” said Jonathan Rigby, President & CEO of SteadyMed. “We look forward to a final decision from the PTAB in April 2017.”
