Abstract: The invention provides compositions and methods useful for the depletion of CD117+ cells and for the treatment of various hematopoietic diseases, metabolic disorders, cancers, e.g., acute myeloid leukemia (AML) and autoimmune diseases, among others. Described herein are antibodies, antigen-binding fragments, and conjugates thereof that can be applied to effect the treatment of these conditions, for instance, by depleting a population of CD117+ cells in a patient, such as a human. The compositions and methods described herein can be used to treat a disorder directly, for instance, by depleting a population of CD117+ cancer cells or autoimmune cells. The compositions and methods described herein can also be used to prepare a patient for hematopoietic stem cell transplant therapy and to improve the engraftment of hematopoietic stem cell transplants by selectively depleting endogenous hematopoietic stem cells prior to the transplant procedure.

Abstract: The present invention is based on the surprising finding that the linker employed in a bioconjugate, such as an anti-body-drug conjugate, is not therapeutically inert but has an effect on the therapeutic index of the bioconjugate. The present invention thus concerns a method for increasing the therapeutic index of a bioconjugate and the bioconjugates for use in treatment, in particular cancer. The bioconjugates according to the invention have a sulfamide linker comprising a group according to formula (1).

Abstract: Mutations in oncogenes and tumor suppressors contribute to the development and progression of cancer. The present disclosure describes methods of recovering wild-type function to p53 mutants by treating a cancer with a compound and a second agent. The compounds of the present invention can bind to mutant p53 and restore the ability of the p53 mutant to bind DNA and activate downstream effectors involved in tumor suppression. The disclosed compounds can be used in combination with a secondary agent to reduce the progression of cancers that contain a p53 mutation.
Abstract: Embodiments of a novel platform for delivering a peptide antigen to a subject to induce an immune response to the peptide antigen are provided. For example, nanoparticle polyplexes are provided that comprise a polymer linked to a peptide conjugate by an electrostatic interaction. The conjugate comprises a peptide antigen linked to a peptide tag through an optional linker. An adjuvant may be included in the nanoparticle polyplex, linked to either the polymer or the conjugate, or admixed with the nanoparticles. The nanoparticle polyplex can be administered to a subject to induce an immune response to the peptide antigen.

Abstract: The present disclosure relates to methods of using antibody conjugates with binding specificity for BCMA (BCMA) and its isoforms and homologs in combination with a gamma secretase inhibitor (GSI), such as in therapeutic methods. Also provided are pharmaceutical compositions and kits comprising the antibody conjugates and GSI.
Abstract: Pharmaceutical compositions comprising antibody-urease conjugates and substantially free of unconjugated urease are disclosed. These compositions are prepared by a method that does not require chromatographic purification. These pharmaceutical compositions have utility in the treatment of cancer by antibody-directed enzyme prodrug therapy wherein the urease converts endogenous urea into ammonia in situ to induce cytotoxicity.
Abstract: Compounds that modulate the oxidoreductase enzyme indoleamine 2,3-dioxygenase, and compositions containing the compounds, are described herein. The use of such compounds and compositions for the treatment and/or prevention of a diverse array of diseases, disorders and conditions, including cancer- and immune-related disorders, that are mediated by indoleamine 2,3-dioxygenase is also provided.

Abstract: The field of this invention relates to immunohistochemistry (IHC) and in situ hybridization (ISH) for the targeted detection and mapping of biomolecules (e.g., proteins and miRNAs) in tissues or cells for example, for research use and for clinical use such by pathologists (e.g., biomarker analyses of a resected tumor or tumor biopsy). In particular, the use of mass spectrometric imaging (MSI) as a mode to detect and map the biomolecules in tissues or cells for example. More specifically, the field of this invention relates to photocleavable mass-tag reagents which are attached to probes such as antibodies and nucleic acids and used to achieve multiplex immunohistochemistry and in situ hybridization, with MSI as the mode of detection/readout. Probe types other than antibodies and nucleic acids are also covered in the field of invention, including but not limited to carbohydrate-binding proteins (e.g., lectins), receptors and ligands.
