The present invention relates to therapeutic conjugates with improved ability to target various diseased cells containing a targeting moiety (such as an antibody or antibody fragment), a linker and a therapeutic moiety, and further relates to processes for making and using the conjugates.

Antibodies that bind SARS-CoV spike protein, SARS-CoV-2 spike protein, and methods of using same for treating or preventing conditions associated with SARS or COVID-19 and for detecting SARS-CoV or SARS-CoV-2.

The present invention relates to therapeutic conjugates with improved ability to target various diseased cells containing a targeting moiety (such as an antibody or antibody fragment), a linker and a therapeutic moiety, and further relates to processes for making and using the conjugates.

Various compositions are disclosed for the treatment of viral infections. The compositions of conjugates comprise antibody constructs attached to myeloid cell agonists via a linker are also provided. Additionally provided are the methods of preparation and use of the conjugates. This includes methods for treating viral infections, such as viral liver diseases.

The present invention provides compounds for use in treating and/or preventing influenza. The compound comprises a first and second domain in which the first domain comprises at least one anchoring group which binds to the surface of influenza viruses and the second domain comprises at least one anionic group. The first and second domains are covalently linked. Also provided are pharmaceutically acceptable salts, solvates, prodrugs or stereoisomer of the compounds.

Provided are a coronavirus spike (S) protein-specific antibody and use thereof.

The invention provides novel cytotoxic compounds and cytotoxic conjugates comprising these cytotoxic compounds and cell-binding agents. More specifically, this invention relates to novel thailanstatin A analogs, useful as cytotoxic small molecule toxins in antibody-drug conjugates (ADCs). The present invention further relates to compositions including these cytotoxic compounds and ADCs, and methods for using these toxins and ADCs to treat pathological conditions including cancer.

##STR00001##

where R.sup.1, R.sup.2, R.sup.3, R.sup.4, Ar and X.sup.1 are as defined herein, are agonists for the Toll-like receptor 7 (TLR7) and can be used as adjuvants for stimulating the immune system. Some such compounds can be used in conjugates for targeted delivery to the organ or tissue of intended action.

Multispecific antibodies (e.g., bispecific antibodies) that bind to HIV gp120 and CD3 are disclosed. Also disclosed are methods of using such antibodies to treat or prevent HIV infection.

The present invention concerns IgA multi-specific binding molecules. In particular, the invention concerns multi-specific, including bispecific, binding molecules comprising IgA heavy chain sequences, and methods for their preparation and use.
