Aspects of the disclosure relate to methods and compositions useful for in vivo and/or in vitro enzyme profiling. In some embodiments, the disclosure provides methods of in vivo enzymatic processing of exogenous molecules followed by detection of signature molecules as representative of the presence of active enzymes associated with diseases or conditions. In some embodiments, the disclosure provides compositions and in vitro methods for localization of enzymatic activity in a tissue sample.

The present invention provides p97-antibody conjugates and related compositions and methods, which may be used in any of a variety of therapeutic methods, including methods for the treatment of cancers such as Her2/neu-expressing and Her1/EGFR-expressing cancers.

Antibody-drug conjugates, compositions thereof, and methods use. The antibody-drug conjugates include a fusion protein comprising an antibody covalently linked to an ADP-ribosyl cyclase protein via a peptide linker moiety at one or more of a C-terminus or N-terminus of a heavy or light chain of the antibody, a NAD or NMN analogue, and a payload such that the NAD or NMN analogue is conjugated to both the payload and the ADP-ribosyl cyclase protein.

The present invention relates to compositions and methods associated with antibody-bacterial effector translocase protein conjugates. Some aspects of the present invention relate to preventing or treating diseases using the antibody-protective antigen conjugates. Further aspects of the present invention relate to methods of chemically conjugating and synthesizing the antibody-bacterial effector translocase protein conjugates.

The invention relates to methods of treating diseases with L-asparaginase.

In one aspect, the present disclosure provides targeted complement-activating molecules comprising a target-binding domain and a complement-activating serine protease effector domain. In some embodiments, the target-binding domain is derived from an antibody or an antigen-binding fragment thereof. Also provided are compositions and methods for treating cancer, autoimmune disease, or microbial infection, including bacterial, viral, fungal, or parasitic infection, using targeted complement-activating molecules.

Novel antibody-drug conjugates (ADCs) and methods of using such ADCs to treat proliferative disorders are described herein. The ADCs may comprise a PARP protein automodified with a plurality of poly-ADP-ribose polymers functionalized with novel NAD.sup.+ analogues. The automodified PARP with functionalized poly-ADP-ribose polymers provide a novel type of drug carrier, which allows facile conjugation of monoclonal antibodies and cytotoxic drug in high ratios.

The present invention relates to a CD43 epitope expressed on human acute leukemia and lymphoblastic lymphoma cells and its use. More particularly, the present invention relates to a CD43 epitope expressed on human acute leukemia, lymphoblastic lymphoma cells, but not on mature hematopoietic cells, hematopoietic stem cells and non-hematopoietic cells, and to its diagnostic and therapeutic application on acute leukemia and lymphoblastic lymphoma.

Disclosed herein are compositions and methods of use comprising hexavalent DNL complexes. Preferably, the complexes comprise anti-CD20 and/or anti-CD22 antibodies or fragments thereof. More preferably, the anti-CD20 antibody is veltuzumab and the anti-CD22 antibody is epratuzumab. Administration of the subject hexavalent DNL complexes induces apoptosis and cell death of target cells in diseases such as B-cell lymphomas or leukemias, autoimmune disease or immune dysfunction disease. In most preferred embodiments, the DNL complexes increase levels of phosphorylated p38 and PTEN, decrease levels of phosphorylated Lyn, Akt, ERK, IKKα/β and IκBα, increase expression of RKIP and Bax and decrease expression of Mcl-1, Bcl-xL, Bcl-2, and phospho-BAD in target cells. The subject DNL complexes show EC.sub.50 values for inhibiting tumor cell growth in the low nanomolar or even sub-nanomolar concentration range.

The invention relates to binding molecules that bind specifically to prostate specific membrane antigen (PSMA), in particular, single human variable heavy chain domain antibodies and related methods for treatment of cancer.
