Patent number: 12623013Abstract: Compounds, systems, kits, methods, and/or apparatuses may be operative to reduce amyloid beta (A?) peptide in a patient, including a central nervous system (CNS) of the patient and/or a periphery (non-CNS portion) of the patient. In some embodiments, a displacer fluid comprising a A? displacer may be introduced to the patient to bind to a blood protein, such as albumin, that binds A? (for instance, A? peptide or non-plaque A?) in the patient periphery. Binding of the displacer to the blood protein may facilitate more free A? peptide (for instance, A? monomers) in the periphery for clearance via natural processes, such as through the liver or kidneys, and/or artificial processes, such as dialysis. Increased removal of the free A? peptide in the periphery may ultimately lead to less A? peptide in the CNS, which may decrease A? plaque formation in Alzheimer's Disease (AD) patients. Other embodiments are described.Type: GrantFiled: December 19, 2022Date of Patent: May 12, 2026Assignee: Fresenius Medical Care Holdings, Inc.Inventors: Xia Tao, Peter Kotanko, Stephan Thijssen, Vaibhav Maheshwari
