Emmaus Life Sciences, Inc. Receives Notice of Allowance for U.S. Patent for use of L-glutamine in Treatment of Diverticulosis

- Related patents previously issued in Japan, China and Australia -
- Patents pending in Europe,  South Korea and other countries - 

TORRANCE, Calif. – February 1, 2017- Emmaus announced today the allowance by the US Patent & Trade Office of patent application number 13/694,592 covering the use of its lead investigative product, pharmaceutical grade L-glutamine (PGLG), for the treatment of diverticulosis. The allowance of this application follows the issuance of corresponding issued patents in Japan, Australia and China. Related patent applications are currently pending in Europe, South Korea, Brazil, Russia, India, Mexico and Indonesia.

The allowed U.S. application reports a significant reduction in the number of intestinal diverticula, the primary indicator of diverticulosis, through therapeutic application of L-glutamine. There are no commercial therapies that claim an ability to reduce intestinal diverticula at the present time. 

The covered invention is directed to a method of treating diverticulosis using L-glutamine.  Diverticulosis refers to a condition where pouches (i.e., diverticula) form along the colon wall. Over time, some people get an infection in the pouches, diverticulitis, which usually requires hospitalization. Epidemiological studies indicate that the prevalence of this disease is increasing worldwide. It is estimated that at least 50% of the population over the age of 60 in the United States, Europe and Australia have diverticulosis. In Japan, a recent study found diverticulosis in 20% of the investigated population (approximate mean age 68 years).

"The US patent further strengthens our broad intellectual property portfolio for PGLG,” said Yutaka Niihara, MD, MPH, Chairman and CEO of Emmaus. “We are very excited about advancing our development program for diverticulosis as we progress through the FDA review of our NDA for sickle cell disease.”

"Diverticulosis and sickle cell disease both represent global unmet needs. We believe that PGLG will have utility in multiple indications as part of our pipeline plan to maximize its utility for people with serious diseases,” added Charles Stark, Pharm.D., Senior Vice President of Research and Development for Emmaus.

In addition to developing PGLG for the treatment of diverticulosis, Emmaus Life Sciences is seeking US Food & Drug Administration (FDA) approval to market the product for the treatment of sickle cell disease in adults and pediatric patients. FDA has set a PDUFA date of July 7, 2017 for a decision on the company’s new drug application for the use of PGLG to treat sickle cell disease.
