The present invention relates to methods of preventing, treating or managing, reducing the risk of stroke or thromboembolism in a subject afflicted with end stage renal disease comprising administering a pharmaceutical composition comprising a monoclonal antibody or an antigen binding fragment thereof that bind to human Factor XI and/or activated Factor XI (“Factor XIa”).

The present application provides anti-CD93 constructs that bind to CD93 (e.g., anti-CD93 antibodies), nucleic acid molecules encoding an amino acid sequence of the anti-CD93, vectors comprising the nucleic acid molecules, host cells containing the vectors, methods of preparing the anti-CD93 construct, pharmaceutical compositions containing the anti-CD93 construct, and methods of using the anti-CD93 construct or compositions.

The present disclosure provides PD-1 binding proteins, particularly anti-PD-1 antibodies, or antigen-binding portions thereof, that specifically bind PD-1 and uses thereof. In one embodiment, the anti-PD-1 antibody comprises an antigen binding portion that binds a human PD-1 epitope or a non-human PD-1 epitope. Various aspects of the anti-PD-1 antibodies relate to antibody fragments, single-chain antibodies, pharmaceutical compositions, nucleic acids, recombinant expression vectors, host cells, and methods for preparing and using such anti-PD-1 antibodies. Methods for using the anti-PD-1 antibodies include in vitro and in vivo methods for binding PD-1, blocking interaction between PD-1 and PD-L1, detecting PD-1, and treating diseases associated with PD-L1 over-expression or PD-L1 detrimental expression.

The invention generally relates to VHH domains that specifically bind a severe acute respiratory syndrome coronavirus spike protein receptor binding domain, corresponding expression vectors and host cells, and methods of treatment using such VHH domains.

Chronic obstructive pulmonary disease (COPD) remains a major cause of morbidity and mortality worldwide. Acute exacerbation of COPD (AE-COPD) in patients are mostly due to respiratory infection and are associated with an inexorable decline in lung function, enhanced oedema as well as airway and systemic inflammation. Previous results show that treatment with anti-IL-20Rb blocking antibodies increased the bacterial clearance in control mice infected by S. pneumoniae and protected CS-exposed mice from bacterial infection, by decreasing the bacterial burden and the inflammatory infiltrate. Therefore there is an interest for generating monoclonal antibodies specific for IL-20Rb with a neutralizing activity for their use in the treatment of AE-COPD. The present invention fulfills this need by providing antibodies having specificity for IL-20Rb.

Provided in the present disclosure are a bifunctional protein which can bind to PD-1 (programmed death receptor-1) and TGF-β (transforming growth factor-β), the medical use of the bifunctional protein, and a preparation method therefor.

Aspects of the disclosure relate to complexes comprising a muscle-targeting agent covalently linked to a molecular payload. In some embodiments, the muscle-targeting agent specifically binds to an internalizing cell surface receptor on muscle cells. In some embodiments, the molecular payload promotes the expression or activity of a functional dystrophin protein. In some embodiments, the molecular payload is an oligonucleotide, such as an antisense oligonucleotide, e.g., an oligonucleotide that causes exon skipping in a mRNA expressed from a mutant DMD allele.

Embodiments of the disclosure include methods and compositions directed to targeting of cells that express the long form of Bone marrow stromal cell antigen 2 (BST2) protein, including cancer cells that express the long isoform of BST2. In particular embodiments, monoclonal antibodies or functionally active fragments thereof are utilized to target cells that express the long isoform of BST2. The monoclonal antibodies or functionally active fragments thereof may be utilized by themselves or as part of other entities, such as cells or engineered antigen receptors. The disclosure includes methods of treatment, prevention, and/or diagnosis using the encompassed antibodies or functional fragments thereof.

The present invention relates to a novel antibody and an antibody fragment that specifically bind to Claudin18.2 and a composition comprising the antibody or the antibody fragment. In addition, the present invention relates to a nucleic acid encoding the antibody or the antibody fragment thereof, a host cell comprising the nucleic acid, and related uses. Furthermore, the present invention relates to therapeutic and diagnostic uses of the antibody and the antibody fragment.

The present invention provides broadly neutralizing antibodies against HIV, compositions comprising the same and methods of use thereof.
