FeRACCRU® will now be indicated for the treatment of iron deficiency in adult and pediatric patients 12 years of age and older. EMA have also confirmed that all measures in the agreed Pediatric Investigation Plan (PIP) for FeRACCRU® have been fulfilled. The indication expansion was supported by positive results from the Phase 3 pediatric clinical trial (FORTIS/ST10-01-305) that confirmed the efficacy, safety, and tolerability of the new oral liquid pediatric formulation in children aged 1 month and above with iron deficiency, presenting as iron deficiency anemia (IDA). Shield's licensing partner, Norgine B.V. holds the marketing authorisation and is responsible for commercialising FeRACCRU® in the European Union. Shield will receive a milestone payment of €500,000 from Norgine related to this EMA approval for the term of the agreement. Anders Lundstrom, CEO of Shield, commented: "We are delighted with the EMA approval of FeRACCRU® for an adolescent population. This follows on from the FDA approval of ACCRUFeR® for adolescents reported in December 2025, further expanding the geographic and age range of patients who can now benefit from a much needed safe and effective oral iron treatment."

Together, ID and ID with anemia (IDA) affect about 20 million people in the US and represent a $2.3B market opportunity. As the first and only FDA approved oral iron to treat ID/IDA, ACCRUFeR® has the potential to meet an important unmet medical need for both physicians and patients and is now the #1 branded prescription oral iron the market today (*data source - IQVIA Xponent PlanTrak). ACCRUFeR®/FeRACCRU® (ferric maltol) is a novel, stable, non-salt-based oral therapy for adults with ID/IDA. The drug has a novel mechanism of absorption compared to other oral iron therapies and has been shown to be an efficacious and well- tolerated therapy in a range of clinical trials.
