We are dedicated to growing sales of Accrufer®/Feraccru® and bringing this important product to patients around the world with iron deficiency. Securing a commercial partnership for Canada is an important part of our strategy and we feel that KYE is the right partner. We look forward to supporting KYE’s efforts to bring Accrufer® to the market in Canada.

“Shield has made significant progress on the commercial launch of Accrufer®/Feraccru® over the last 12 months by implementing important geographic partnerships and successfully securing payer coverage with several large pharmacy benefit managers. We look forward to continuing to expand the awareness of Accrufer®/Feraccru® among healthcare professionals in 2022.”

Doug Reynolds, President of KYE, commented: “Iron deficiency is highly prevalent worldwide and a public health concern in Canada. Accrufer® will be the first oral prescription only therapy available in Canada to treat patients who continue to suffer from low iron despite attempts at treatment with currently available agents. This agreement is very much aligned with our strategy to bring innovative medicines to the people of Canada and KYE is proud to be partnering with Shield.
