This invention concerns the treatment of HER-2 positive breast cancer cells by mediating the signal of GRB7 using an anti-HER-1 antibody, such as panitumumab.

The present invention relates to an antibody drug conjugate (ADC) of general formula (I) (D-Lk.sub.1-C(O)-Lk.sub.2-C.sub.2H.sub.4—NH-Lk.sub.3).sub.n-Ab. A pharmaceutical composition comprising, in a pharmaceutically acceptable medium, the said ADC is also concerned by the present invention, as well as the use of this ADC or composition as a medicament, and in particular in the prevention and/or the treatment of an anti-Müllerian hormone type II receptor (AMHRII) expressing cancer in an individual.

The present invention relates to oligonucleotide conjugates and preparation and applications thereof. In particular, the present invention relates to an oligonucleotide conjugated to a biomolecule (e.g. an antibody) and/or an agent of interest (e.g. a drug). In certain embodiments, the oligonucleotide of the present invention is a hybridized complex of a single strand oligonucleotide carrying a biomolecule and a complementary strand oligonucleotide bearing an agent of interest where the hybridized nucleotide segment acts as a linker to link the biomolecule and the agent of interest in one molecule.

Provided herein are compositions comprising VHH conjugates and their uses in treating diseases.

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.

Isolated polypeptides having a heavy chain variable region and/or light chain variable region that specifically binds to Nectin-4 protein as well as antibodies and antibody fragments containing the heavy chain variable region and/or the light chain variable region that bind to Nectin-4 protein. Pharmaceutical compositions and kits comprising the polypeptide and antibodies and antibody fragments containing the polypeptide are also provided.

The application is drawn to radiohalogen prosthetic moieties and precursors thereof and to radiolabeled biomolecules comprising such radiohalogen prosthetic moieties. The biomolecules have an affinity for particular types of cells and may specifically bind a certain cell, such as a cancer cell. Relevant biomolecules include antibodies, monoclonal antibodies, antibody fragments, peptides, other proteins, nanoparticles, aptamers, and pharamacological moieties used to target prostate-specific membrane antigen (PSMA).

The present disclosure relates to conjugates for delivering therapeutics across the blood brain barrier (BBB) and more particularly to conjugates comprising at least one BBB-shuttling VNAR domain operably linked to a neurotrophic agonist antibody (NAAb), with the conjugate being capable of uptake across a mammalian blood brain barrier (BBB) in a therapeutically-effective amount. These conjugates are useful for treating neurodegenerative diseases, conditions which responds to activation of a neurotrophin receptor as well as for stimulating neuronal survival, growth, repair or regeneration.
