  • Publication number: 20240131172
    Abstract: The present disclosure relates to methods of reducing accelerated blood clearance of at least one pegylated therapeutic composition in a subject suffering from a disease and in need of treatment. The methods involve administering at least one high molecular weight polyethylene glycol composition to a subject suffering from a disease. The administration of at least one high molecular weight polyethylene glycol composition can also be used to increase the circulation half-life of at least one pegylated therapeutic composition as well as restore the pharmacokinetics of the pegylated therapeutic composition in a subject having a high titer of anti-polyethylene glycol antibodies.

  • Publication number: 20230129210
    Abstract: Described herein are binding proteins useful against ACE2-targeted viruses (e.g., SARS-CoV and SARS-CoV-2, etc.), and methods of using them. These binding proteins may include an extracellular portion of angiotensin-converting enzyme 2 (ACE2), excluding the collectrin domain, and a flexible polypeptide flexible linker coupling the ACE2 portion to a fragment crystallization (Fc) domain. These binding proteins dimerize, and the flexible linker may be chosen to be sufficiently long to permit concurrent interaction with multiple Spike (S) proteins on the ACE2-targeted virus.
