These antibodies are proteins used by the body’s immune system to neutralize microbes, such as bacteria and viruses, and prevent infection and disease.Asceniv is indicated for the treatment of PIDD or inborn errors of immunity in adults and adolescents. It is manufactured using ADMA’s unique, patented plasma donor screening methodology and tailored plasma pooling design, which blends normal source plasma with respiratory syncytial virus plasma obtained from donors tested using the company’s proprietary microneutralization assay.Demand was record high in the first quarter. Consequently, ADMA expects Asceniv’s total revenue share to expand throughout 2025 and beyond.ADMA expects to generate initial, proof-of-concept animal data before 2025-end for its lead R&D pipeline program, SG-001, a hyperimmune globulin targeting S. pneumonia.ADMA believes that SG-001 has the potential to generate $300-500 million or more in high-margin annual revenues, with IP protection through at least 2037.The Case for GRFSGrifols, a leading global specialty plasma therapeutics company, is developing, manufacturing and distributing a broad range of biological medicines based on plasma-derived proteins.These protein-based therapies target primary and secondary immunological deficiencies, chronic Inflammatory Demyelinating Polyneuropathy (“CIDP”), A1PI deficiency and related emphysema, immune-mediated ITP, Guillain Barré syndrome, Kawasaki disease, allogeneic bone marrow transplants, hemophilia A and B, von Willebrand disease, traumatic or hemorrhagic shock and severe burns.The main plasma products GRFS manufactures are IG, Factor VIII, Alpha 1 (A1PI) and albumin.
