FDA Approves Grifols' Yimmugo® for Primary Immunodeficiency, Marking a Milestone

Grifols announced that the U.S. Food and Drug Administration (FDA) has granted approval to Yimmugo®, a pioneering immunoglobulin therapy. Developed by Biotest, this approval not only enhances Grifols' robust portfolio of plasma-derived medicines but also marks Yimmugo® as the first U.S.-approved product in Biotest’s lineup.

Yimmugo® is an intravenous immunoglobulin (IVIg) used for substitution therapy in patients with primary antibody deficiency syndromes, where parts of the body's immune system are either missing or function improperly. This approval follows its successful launch in Europe, and it is manufactured in Biotest’s new FDA-certified ‘Next Level’ facility in Dreieich, Germany, which employs a state-of-the-art process to ensure the highest product quality.

A Broader Impact on Global Healthcare

Roland Wandeler, President of Grifols Biopharma Business Unit, emphasized the importance of this development: “The addition of Biotest’s Yimmugo to our strong portfolio of intravenous and subcutaneous immunoglobulins provides another innovative treatment option for patients with primary immunodeficiencies who rely on these essential medicines in their daily lives.”

Grifols' acquisition of Biotest has not only broadened its innovative capabilities but also deepened its product pipeline, further cementing its leadership in the industry. With over 390 donation centers worldwide, Grifols continues to lead in transfusion medicine and plasma collection, offering a comprehensive range of therapeutic solutions across various areas including immunology, hepatology, pulmonology, and neurology.

Safety and Usage

Yimmugo®, while revolutionary, requires careful administration. It does not contain sucrose, which reduces the risk of renal dysfunction—a common side effect with other IGIV products. However, it is still essential to monitor patients for signs of thrombosis and assess blood viscosity, especially in those at risk for hyperviscosity.

For those at risk of thrombosis or renal failure, Yimmugo should be administered at the minimum dose and infusion rate practicable. Patients should be adequately hydrated before administration, and continuous monitoring for signs and symptoms of thrombosis is advised.
