NOVATO, Calif., Aug. 5, 2014 (GLOBE NEWSWIRE) -- Ultragenyx Pharmaceutical Inc. (Nasdaq:RARE), a biopharmaceutical company focused on the development of novel products for rare and ultra-rare diseases, today announced a license agreement with UniQuest Pty Limited for intellectual property related to the treatment of refractory epilepsy and other seizure-related and neurologic disorders with triheptanoin (UX007). The intellectual property originated from research on epilepsy and other neurologic models conducted at The University of Queensland.

Separately, a United States (U.S.) patent has been issued with claims directed to compositions of triheptanoin above a certain level of purity. The patent term expires in October 2025. A second U.S. patent with claims directed to compositions of triheptanoin in a dosage unit was issued in August 2013 and expires in June 2020. These patent terms do not include any potential for patent term extension of up to five additional years. Similar claims are either granted or being pursued by Ultragenyx in other territories outside the U.S.

"The completion of the license agreement with UniQuest and the issuance of additional composition patent claims mark the continued strengthening of our triheptanoin portfolio," commented Emil D. Kakkis, Ph.D., M.D., Chief Executive Officer and President of Ultragenyx. "We are excited about the potential for triheptanoin to be used in certain difficult-to-treat seizure disorders and hope it will provide a new treatment option for affected patients."

About Refractory Epilepsy

Epilepsy is a family of chronic neurological disorders characterized by spontaneous recurrent seizures. There are approximately two million epilepsy patients in the U.S. of various types, some of which are genetic in origin. Refractory epilepsy occurs in patients whose seizures cannot be adequately controlled by anti-epileptic drugs, which happens in approximately one third of cases.

About Triheptanoin

Triheptanoin, also known as UX007, is a purified form of a specially designed synthetic triglyceride compound. Ultragenyx is currently evaluating triheptanoin in two clinical programs.

The first program is studying the genetic seizure disorder Glut1 deficiency syndrome (Glut1 DS). This disease is caused by a genetic defect in the transport of glucose into the brain and affects an estimated 3,000 to 7,000 patients in the U.S. Glut1 DS is characterized by seizures, developmental delay, and movement disorder. Triheptanoin is metabolized to and intended to provide patients with heptanoate, which can diffuse across the blood-brain barrier and be converted into glucose. Heptanoate can also be further metabolized to four- and five-carbon ketone bodies in the liver that also cross the blood-brain-barrier and provide an additional energy source to the brain. Heptanoate and five-carbon ketone bodies can also regenerate new glucose in the brain, which is deficient in these patients. Ultragenyx is conducting a Phase 2 study in the U.S. and Europe to evaluate the potential of triheptanoin to treat Glut1 DS patients who have failed the ketogenic diet and who continue to have breakthrough seizures.

The second program is studying long-chain fatty acid oxidation disorders (LC-FAOD), a set of rare metabolic diseases caused by the inability to convert fat into energy, leading to low blood sugar, muscle rupture, and heart and liver disease. Triheptanoin is intended to provide patients with medium-length, odd-chain fatty acids that are metabolized to increase intermediate substrates in the Krebs cycle, a key energy-generating process. Unlike typical even-chain fatty acids, triheptanoin can be converted to new glucose through the Krebs cycle, potentially providing an important added therapeutic effect, particularly when glucose levels are too low. Ultragenyx is conducting a Phase 2 study to evaluate the potential of triheptanoin to treat LC-FAOD.
