  • 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: 20240115781
    Abstract: Systems and apparatuses for blood oxygenation are disclosed. A system includes a first layer defining a plurality of banks of first channels each extending in a first direction. The plurality of banks of first channels are configured to receive blood via a trunk channel. The system includes a second layer defining a bank of second channels extending in a second direction. The bank of second channels are configured to receive oxygen. The first direction is different from the second direction. The system includes a membrane disposed between the first layer and the second layer and configured to cause the oxygen to permeate from the second layer to the first layer to oxygenate the blood.

  • Patent number: 11897939
    Abstract: The presently-disclosed subject matter relates to antibodies, compositions, and methods for inhibiting and treating virus infection in the respiratory tract and virus transmission through the respiratory tract. In particular, the presently-disclosed subject matter relates to inhibiting and treating virus infection in a subject using compositions and antibodies that trap viruses in mucus of the respiratory tract, thereby inhibiting transport of virus across or through mucus secretions.

  • 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.
