PTC Therapeutics Announces Agreement to Acquire Emflaza™ from Marathon Pharmaceuticals, LLC

Friday, March 17, 2017

PTC Therapeutics, Inc. announced it has entered into an asset purchase agreement with Marathon Pharmaceuticals, LLC to acquire all rights to Emflaza™ (deflazacort). Emflaza is the first treatment approved in the United States for all Duchenne muscular dystrophy (DMD) patients five years and older, regardless of their genetic mutation. DMD is a rare and fatal genetic disorder that results in progressive muscle weakness from early childhood and leads to premature death due to heart and respiratory failure. Emflaza aligns with PTC's mission to bring therapies to patients who have rare diseases with limited or no treatment options.

"With our nearly 20-year commitment to the Duchenne community, it is deeply meaningful for us to bring this critical therapy to U.S. patients," said Stuart W. Peltz, Ph.D., chief executive officer of PTC Therapeutics, Inc. "We believe Emflaza is a disease-modifying therapy that has been shown to slow disease progression. In keeping with PTC's mission, we are excited to work with the community to raise the standard of care for DMD patients."

DMD treatment guidelines recommend steroids as a foundational component of the standard of care. Emflaza reduces inflammation, which is critical to preserving muscle function and delaying disease progression. It received FDA approval on February 9, 2017 and has the potential to benefit many DMD patients in the U.S.

"Our goal has always been to ensure Emflaza is studied, understood and available to any Duchenne patient who needs it, and we determined that this transaction is the best path for ensuring that will happen," said Jeff Aronin, president and CEO, Marathon Pharmaceuticals, LLC.  "Now that we have achieved FDA approval of Emflaza, the focus can turn to ensuring patients have access to this important therapy. PTC is well known by the Duchenne community and is ideally positioned to achieve this shared goal."

"Based on our long-standing experience with DMD and strong partnership with the community, we believe PTC is uniquely positioned to launch Emflaza in the U.S.," added Mark Rothera, PTC's chief commercial officer. "We are finalizing our commercialization plans and intend to share more information after the transaction closes."
