Provided is a conjugate comprising a ligand, a spacer, and a peptide linker useful for an in-vivo diagnostic drug and internal radiation therapy, using an anti-human CEACAM5 antibody Fab fragment whose binding activity is not attenuated even by labeling with a metal, a fluorescent dye, or the like. A conjugate comprising an anti-human CEACAM5 antibody Fab fragment and a ligand, the fragment comprising a heavy chain fragment including a heavy chain variable region consisting of a specific amino acid sequence and a light chain including a light chain variable region consisting of a specific amino acid sequence, or a conjugate comprising a ligand, a spacer, and a peptide linker, wherein the binding activity thereof is not attenuated even by labeling with a metal, a fluorescent dye, or the like, can be used as a diagnostic composition and/or a pharmaceutical composition.

The present disclosure provides methods of treating high CEACAM5 expressing cancers including lung cancers such NSQ NSCLC using immunoconjugates comprising an antibody that specifically binds human CEACAM5.

The present invention relates to bi-specific antigen binding molecules and associated fusion proteins and conjugates. In particular, the present invention relates to bi-specific antigen binding molecules with specificity for both receptor tyrosine kinase-like orphan receptor 1 (ROR1) and epidermal growth factor receptor (EGFR) and associated fusion proteins and conjugates. In a further aspect, the present invention relates to conjugated immunoglobulin-like shark variable novel antigen receptors (VNARs).

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.

The present invention generally relates to antigen-specific immunoconjugates for selectively delivering effector moieties that influence cellular activity. More specifically, the invention provides novel immunoconjugates comprising a first antigen binding moiety, an Fc domain and a single effector moiety. In addition, the present invention relates to polynucleotides encoding such immunoconjugates, and vectors and host cells comprising such polynucleotides. The invention further relates to methods for producing the immunoconjugates of the invention, and to methods of using these immunoconjugates in the treatment of disease.

The present invention concerns improved methods and compositions for neoadjuvant use of antibody-drug conjugates (ADCs) in cancer therapy, preferably ADCs comprising an anthracycline or camptothecin, more preferably SN-38 or pro-2-pyrrolinodoxorubicin (P2PDox). The ADC is administered as a neoadjuvant, prior to treatment with a standard anti-cancer therapy such as surgery, radiation therapy, chemotherapy, or immunotherapy. Neoadjuvant use of the ADC substantially improves the efficacy of standard anti-cancer therapy and may debulk a primary tumor or eliminate micrometasteses. In most preferred embodiments, neoadjuvant ADC in combination with a standard anti-cancer therapy is successful in treating cancers that are resistant to standard treatments, such as triple-negative breast cancer (TNBC).

Provided herein are cytokine muteins and cytokine prodrugs and methods of making and using thereof.

The present invention relates to a novel interleukin-2 (IL-2) mutant protein and use thereof. In particular, the present invention relates to an IL-2 mutant protein with reduced IL-2Rα receptor binding ability and/or increased IL-2Rβ receptor binding ability compared with the wild-type IL-2. The present invention further provides a fusion protein and an immunoconjugate comprising the IL-2 mutant protein, a nucleic acid encoding the IL-2 mutant protein, and a vector and a host cell comprising the nucleic acid. The present invention further provides a method for preparing the IL-2 mutant protein, a pharmaceutical composition comprising the IL-2 mutant protein, and therapeutic use of the mutant protein.

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.
