Emmaus Life Sciences Announces Strategic Transaction

Enters into North American License and Exclusive Distribution Agreement

TORRANCE, Calif.–(BUSINESS WIRE)–Emmaus Life Sciences, Inc. (OTCQB: EMMA), a commercial-stage biopharmaceutical company and leader in the treatment of sickle cell disease, today announced that it has entered into a License and Exclusive Distribution Agreement with NeoImmuneTech, Inc. (KOSDAQ:950220), or NIT, pursuant to which Emmaus has granted NIT an exclusive license to all rights to market, sell and distribute Endari® (prescription grade L-glutamine oral powder) and any generic equivalents in sickle cell disease in the U.S., its territories, and Canada in exchange for a upfront payment and a royalty on NIT’s product sales.

The effective date is subject to NIT’s obtaining the necessary regulatory approvals and licensing to sell and distribute the products and other specified conditions.

“Emmaus has continuously reassessed its commercialization strategy to maximize global value of Endari®. While the U.S. market represents a mature and stable revenue base, we believe other regions such as the Middle East, Brazil, and Europe offer greater growth potential,” commented Willis Lee, Chairman and Chief Executive Officer of Emmaus.

Tae Woo Kim, Acting Chief Executive Officer of NeoImmuneTech, said, “The completion of this definitive agreement is highly meaningful, as it establishes a foundation for direct commercialization of an FDA-approved therapy. The U.S. distribution, reimbursement, and marketing infrastructure built through Endari® will also create significant synergies for the future commercialization of our proprietary pipeline, including NT-I7.”

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
