Cardiome's Partner SteadyMed Receives Favourable Ruling in its USPTO Inter Partes Review

NASDAQ: CRME     TSX: COM

VANCOUVER, April 3, 2017 /PRNewswire/ - Cardiome Pharma Corp. (NASDAQ: CRME / TSX: COM) updated today that its partner, SteadyMed Therapeutics (NASDAQ: STDY), announced a favourable outcome of its Inter Partes Review (IPR) by the Patent Trial and Appeal Board (PTAB) of the United States Patent Trademark Office (USPTO). The IPR was accessing the validity of U.S. Patent No. 8,497,393 (the '393 patent) owned by United Therapeutics (NASDAQ: UTHR). In its ruling, the PTAB found all 22 claims of the '393 patent were unpatentable.  The IPR ruling verdict applies only to the '393 patent, which is only relevant within the United States and therefore is not directly related to Cardiome's license of Trevyent for markets outside of the United States. Cardiome does not believe that an equivalent patent has been granted in Europe. United Therapeutics may appeal the verdict.

SteadyMed provided background on the ruling within its March 31, 2017 release: "The IPR was instituted by PTAB in April 2016 after SteadyMed challenged the '393 patent's validity. The '393 patent claims a product made by 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, which is in development for the treatment of Pulmonary Arterial Hypertension (PAH)."

Commenting on the decision, David Dean, Cardiome's VP Business Development said  "We are pleased to see this news from SteadyMed as it should facilitate Trevyent's regulatory and commercial pathway in the United States. While Cardiome has no economic interest in Trevyent within the United States, and we do not believe that a similar patent exists in the territories we have licensed from SteadyMed, Trevyent's success in the United States can only benefit Trevyent within Cardiome's territories."

In addition, within its press release on March 31, 2017, SteadyMed maintained its guidance that it currently expects to file Trevyent's New Drug Application (NDA) with the US Food and Drug Administration (FDA) by the end of the second quarter of 2017. Cardiome currently expects to file for European Medicines Agency (EMA) approval of Trevyent during 2017.

About Pulmonary Arterial Hypertension
Pulmonary arterial hypertension is a type of high blood pressure that occurs in the right side of the heart and in the arteries that supply blood to the lungs. PAH worsens over time and is life-threatening because the pressure in a patient's pulmonary arteries rises to dangerously high levels, putting a strain on the heart. There is no cure for PAH, but several medications are available to treat symptoms, such as the market-leading prostacyclin PAH therapy, Remodulin^® (treprostinil sodium), which is produced by United Therapeutics Corporation. The annual cost of Remodulin is reported to be between approximately $125,000 and $175,000 per patient and United Therapeutics reported Remodulin revenues of $602 million in 2016.
