The U.S. Food and Drug Administration (FDA) approved Endari (L-glutamine oral powder) for patients age five years and older with sickle cell disease to reduce severe complications associated with the blood disorder.
“Endari is the first treatment approved for patients with sickle cell disease in almost 20 years,” said Richard Pazdur, M.D., acting director of the Office of Hematology and Oncology Products in the FDA’s Center for Drug Evaluation and Research and director of the FDA’s Oncology Center of Excellence. “Until now, only one other drug was approved for patients living with this serious, debilitating condition.”
Sickle cell disease is an inherited blood disorder in which the red blood cells are abnormally shaped (in a crescent, or “sickle,” shape). This restricts the flow in blood vessels and limits oxygen delivery to the body’s tissues, leading to severe pain and organ damage. According to the National Institutes of Health, approximately 100,000 people in the United States have sickle cell disease.
Endari received Orphan Drug designation for this use, which provides incentives to assist and encourage the development of drugs for rare diseases. In addition, development of this drug was in part supported by the FDA Orphan Products Grants Program, which provides grants for clinical studies on safety and/or effectiveness of products for use in rare diseases or conditions.
The FDA granted the approval of Endari to Emmaus Medical Inc.
