TORRANCE, Calif., July 13, 2023 /PRNewswire/ -- Emmaus Life Sciences, Inc.

"This approval marks another milestone in our mission to improve the lives of people with sickle cell disease around the world."

"The Omani marketing approval for Endari is an important step forward for us in the GCC region, where we have been working closely with the local authorities, physicians, and patient groups to ensure access to this innovative treatment for sickle cell disease," said George Sekulich, Senior Vice President of Global Commercialization of Emmaus Life Sciences, Inc. "We look forward to launching Endari® commercially in Oman and expanding its availability to other countries in the region."

Endari® is also approved for marketing in the United States, Israel, Bahrain, Kuwait, Qatar, and the United Arab Emirates and is available on a named patient or early access basis in France, The Netherlands, and the Kingdom of Saudi Arabia. Emmaus is pursuing additional regulatory approvals for Endari® in other countries where sickle cell disease is prevalent.

About Sickle Cell Disease
There are approximately 100,000 people living with sickle cell disease (SCD) in the United States and millions more globally. The sickle gene is found in every ethnic group, not just among those of African descent; and in the United States an estimated 1-in-365 African Americans and 1-in-16,300 Hispanic Americans are born with SCD.¹ The genetic mutation responsible for SCD causes an individual's red blood cells to distort into a "C" or a sickle shape, reducing their ability to transport oxygen throughout the body. These sickled red blood cells break down rapidly, become very sticky, and develop a propensity to clump together, which causes them to become stuck and cause damage within blood vessels. The result is reduced blood flow to distal organs, which leads to physical symptoms of incapacitating pain, tissue and organ damage, and early death.²
