TORRANCE, Calif., Sept. 19, 2019 /PRNewswire/ -- Emmaus Life Sciences, Inc. (OTC: EMMA), a leader in sickle cell disease treatment, today announced the withdrawal of its marketing authorization application (MAA) to the European Medicines Agency (EMA) for Xyndari™ (glutamine) for the treatment of sickle cell disease.

Xyndari was approved under the tradename Endari^® (L-glutamine oral powder) by the FDA to reduce the acute complications of sickle cell disease in adult and pediatric patients five years of age and older, based on the results of a Phase 3 study and other supportive studies.  Despite the results of the Phase 3 study and other data submitted to the EMA's Committee for Medicinal Products for Human Use (CHMP), the CHMP maintains its initial opinion that the MAA did not demonstrate that Xyndari is effective at reducing the number of sickle cell disease crises or hospital visits. 

"Because we have demonstrated the efficacy of Xyndari, as supported by the data from the trials conducted, we are disappointed in the CHMP's position," said Yutaka Niihara, M.D., M.P.H., Chairman and Chief Executive Officer of Emmaus.  "We remain committed to the patients who suffer from sickle cell disease and will continue to endeavor to broaden our global patient base, while identifying new clinical uses for L-glutamine, obtaining additional patents and distribution partners, and through ongoing community and physician outreach. We are seriously considering a decentralized approval procedure on a country by country basis."

Outside the United States, Xyndari is currently supplied through early access programs based on named patient use in a number of EU member states, Turkey and the Middle East.  Xyndari received orphan designation by the European Commission in 2012 for the treatment of sickle cell disease and has also received an approved pediatric investigation plan (PIP) from the EMA.

About Sickle Cell Disease
Sickle cell disease is an inherited blood disorder characterized by the production of an altered form of hemoglobin which polymerizes and becomes fibrous, causing red blood cells to become rigid and change form so that they appear sickle shaped instead of soft and rounded.  Patients with sickle cell disease suffer from debilitating episodes of sickle cell crises, which occur when the rigid, adhesive and inflexible red blood cells occlude blood vessels.  Sickle cell crises cause excruciating pain as a result of insufficient oxygen being delivered to tissue, referred to as tissue ischemia, and inflammation.  These events may lead to organ damage, stroke, pulmonary complications, skin ulceration, infection and a variety of other adverse outcomes.  Sickle cell disease is a significant unmet medical need, affecting approximately one hundred thousand patients in the U.S. and millions worldwide, the majority of which are of African descent.  An estimated 1-in-365 African-American children is born with sickle cell disease.
