PKU GOLIKE® is a commercial ultra-rare disease medical formula complementary to Eton's existing metabolic franchise and specialty call pointTransaction is expected to be accretive to 2024 earningsEstimated peak sales of more than $10 million annuallyU.S. phenylketonuria ("PKU") medical formula market estimated to be $100 million annually DEER PARK, Ill., March 22, 2024 (GLOBE NEWSWIRE) -- Eton Pharmaceuticals, Inc (“Eton” or the “Company”) (Nasdaq: ETON), an innovative pharmaceutical company focused on developing and commercializing treatments for rare diseases, today announced that it has acquired U.S. rights to PKU GOLIKE® from RELIEF THERAPEUTICS Holding SA (“Relief”) (SIX: RLF, OTCQB: RLFTF, RLFTY). “We are excited to be partnering with Relief on PKU GOLIKE in the United States. After extensive discussions with metabolic geneticists, dieticians, and PKU patients, we believe PKU GOLIKE is the best product in the estimated $100 million U.S. PKU medical formula market. With our sales force and existing relationships in the metabolic community, we believe we can significantly increase the awareness, education, and adoption of this important product,” said Sean Brynjelsen, CEO of Eton Pharmaceuticals. “We are very pleased to gain this partnership with Eton for PKU GOLIKE patients in the US as it is aligned with RELIEF’s strategy to enhance patient access to our innovative products,” said Michelle Lock, interim CEO of Relief. “Eton brings valuable know-how in the metabolic space as well as commercialization expertise for products in rare diseases.” PKU is a rare inherited disorder caused by a defect in the enzyme needed to break down phenylalanine, leading to a toxic buildup of phenylalanine when eating foods that contain proteins. Treatment of PKU requires patients to follow a strict diet that severely limits phenylalanine content and typically requires low protein foods supplemented by phenylalanine-free medical formulas. Excessive levels of phenylalanine in the blood accumulate in the brain and inhibit proper brain development. It is estimated that 8,000 PKU patients in the U.S. utilize medical formulas to manage their diet. PKU GOLIKE® is a next generation medical formula product engineered with the patent protected, pharmaceutical grade Physiomimic™ technology for the dietary management of PKU under medical supervision. PKU GOLIKE’s taste-masked, odor-free coating technology is designed to provide a better taste and a superior experience compared to alternative PKU medical formulas. In addition, PKU GOLIKE’s delayed amino acid release formulation is designed to keep patients full for a longer period of time. Relief launched PKU GOLIKE Granules in the United States in the fourth quarter of 2022 and the PKU GOLIKE Tropical Bar in the second quarter of 2023. Only a few months into the product’s launch, PKU GOLIKE’s fourth quarter net sales in the U.S. were at an annual run rate of more than $1 million. Relief, through its subsidiary APR, has commercialized PKU GOLIKE in Europe since 2019 and seen strong adoption. Eton plans to promote PKU GOLIKE with its existing metabolic sales force, which currently promotes Eton’s Carglumic Acid, Betaine, and Nitisinone products. PKU patients’ care is typically overseen by metabolic geneticists and their support staff of nurse practitioners and registered dieticians. Medical formulas for PKU are frequently covered by insurance and are regulated by the FDA as medical food products. PKU GOLIKE is exclusively distributed in the United States by Pentec Health. Patients and healthcare professionals seeking additional information on the product can visit www.PKUGOLIKE.com. The transaction is expected to be accretive to Eton’s 2024 earnings and the company expects peak sales of more than $10 million annually. As part of the transaction, Eton also received U.S. rights to Relief’s GOLIKE medical formulas line extensions under development for the management of the metabolic conditions tyrosinemia and homocystinuria, which are expected to launch in 2025 and 2026, respectively. Eton has also been granted a right of first negotiation for Relief’s RLF-OD032 development candidate. RLF-OD032 is an innovative drug product candidate under development for the treatment of PKU and is expected to be filed with the FDA in the second half of 2025 as a 505(b)(2) New Drug Application. Relief will continue to own PKU GOLIKE rights outside the United States.

About Phenylketonuria (PKU) Phenylketonuria (PKU) is caused by a defect of the enzyme needed to break down phenylalanine (Phe), leading to a toxic buildup of Phe from the consumption of foods containing protein or aspartame. Untreated PKU can result in global developmental delay or severe irreversible intellectual disability, as well as growth failure, hypopigmentation, motor deficits, ataxia and seizures. Living with PKU requires a limited diet and very careful management. If left unmanaged, PKU can lead to devastating consequences, such as brain damage. People living with PKU do not have the ability to metabolize Phe, which is found in many foods, and they require supplementation of amino acid-based phenylalanine-free medical formulas as part of an effort to prevent protein deficiency and optimize metabolic control. Medical formulas used in PKU are challenged to provide a range of amino acids slowly and without a medicinal aftertaste. About PKU GOLIKE PKU GOLIKE® products are foods for special medical purposes (FSMPs) for the dietary management of PKU in both children and adults for use under medical supervision. Developed with Relief’s proprietary, patent-protected Physiomimic Technology™ drug delivery platform, PKU GOLIKE® products are the first prolonged-release amino acid FSMPs, characterized by a special coating that ensures physiological absorption of the amino acids mirroring that of natural proteins. The special coating also masks the unpleasant taste, odor and aftertaste of the amino acids. PKU GOLIKE® granules are flavorless and can be mixed with many foods. PKU GOLIKE® products contain all 19 amino acids that people with PKU need to maintain neurological and muscular health and is fortified with 27 essential vitamins and minerals, including ones normally found in protein-rich foods like iron, calcium and vitamin B12. The PKU GOLIKE® line of products are available in convenient packets (PKU GOLIKE Plus® 3-16 and 16+) and medical formula bars (PKU GOLIKE BAR®). PKU GOLIKE® products have been commercially available in the U.S. since October 2022. For more information, visit www.pkugolike.com (Please note this site is intended for U.S. audiences only).
