WARREN, N.J., March 03, 2022 (GLOBE NEWSWIRE) -- Aquestive Therapeutics, Inc. (NASDAQ: AQST) (“Aquestive”), a pharmaceutical company advancing medicines to solve patients’ problems with current standards of care and provide transformative products to improve their lives,  announced the execution of a License, Development and Supply Agreement with Haisco Pharmaceutical Group Co., Ltd. (SZSE: 002653) (“Haisco”), a pharmaceutical company based in the People’s Republic of China (“China”), for Haisco to develop and exclusively commercialize EXSERVAN™ (riluzole oral film) for the treatment of amyotrophic lateral sclerosis (“ALS”) in China.

Around 85% of ALS patients suffer from a progressive loss of bulbar functionality.¹ Swallowing food and liquids becomes more difficult over time. While most patients initiate on riluzole, some choose to discontinue treatment at various points in the disease progression due to an inability to swallow a tablet. EXSERVAN™ is designed to provide a meaningful treatment option, using Aquestive’s orally administered PharmFilm® dosage form, to patients and caregivers. It alleviates the need for swallowing a tablet and water, while having a negligible impact on volume and viscosity of normal saliva.

“This agreement with Haisco will allow ALS patients in China to access EXSERVAN, a riluzole oral film, which will provide a meaningful treatment option to those who have to discontinue their treatment because of difficulties swallowing a tablet. This collaboration perfectly aligns with our mission to design patient-preferred medicines for their safety, efficacy, and ease of use,” remarked Keith Kendall, Chief Executive Officer of Aquestive.

Pursuant to the agreement, Haisco will lead the regulatory and commercialization activities for EXSERVAN in China. Aquestive will serve as the exclusive sole manufacturer and supplier for the product. Aquestive will receive a $7million upfront cash payment, regulatory milestone payments, and double-digit royalties on net sales of EXSERVAN in China, and will earn manufacturing revenue as the exclusive supplier of EXSERVAN.

EXSERVAN, an oral film formulation of riluzole, was developed by Aquestive using its PharmFilm® innovative drug delivery technology.

Oral film riluzole was approved by the U.S. Food and Drug Administration (FDA) in November 2019. Aquestive has entered into separate license and supply agreements for EXSERVAN in Europe with Zambon S.p.A. and in the Unites States with Mitsubishi Tanabe Pharma America.
