Pending a successful review, approval of Accrufer® in Korea is anticipated in 2025. Korea Pharma's MFDS filing follows the successful completion of a pharmacokinetic (PK) study in Korea. The PK study confirms that the absorption of iron from Accrufer® is comparable between patients in Korea and the patient population enrolled in the key clinical studies supporting Accrufer® effectiveness and safety. Shield is eligible to receive a development milestone payment of c.$1.9 upon the first sale of Accrufer® in the territory, as well as future commercial sales milestone payments upon the achievement of specified net sales targets. For the duration of the intellectual property, Shield will also receive double-digit royalties on net sales of Accrufer® in Korea. Shield will be responsible for the initial manufacturing and supply to Korea Pharma. Greg Madison, CEO of Shield, commented: "Iron deficiency anaemia is a global issue. Shield is committed to working with valued partners, such as Korea Pharma, to enable global access of Accrufer® and advance the care of patients with iron deficiency anaemia around the world. Completion of the MFDS filing by Korea Pharma marks the first filing for Accrufer® in Southeast Asia. We are thrilled to work with our partner to reach this important milestone. We look forward to supporting Korea Pharma as they continue the pathway to making Accrufer® available to patients in Korea." Eun-Hee Park, Korea Pharma CEO, commented: "We are pleased by the positive results for the local PK study. These data enabled us to successfully complete a regulatory filing for Accrufer® with the MFDS. There are an estimated 5.2 million people in the Republic of Korea with iron deficiency and iron deficiency anaemia in need of novel treatment options. Pending approval of the NDA, we look forward to providing Accrufer® to the people of Korea as a potential first choice for the treatment of iron deficiency anaemia."
