The present disclosure provides antibody sequences found in antibodies that bind to human CD38. In particular, the present disclosure provides sequences of anti-human CD38 antibodies. Antibodies and antigen-binding portions thereof including such sequences present features compatible with pharmaceutical manufacturing and development can be provided as fully human antibodies (e.g., fully human monoclonal antibodies or antigen-binding fragments) that can be useful for medical methods and compositions, in particular for treating cancer.

The present invention relates to monospecific or bispecific antibody molecules that specifically bind antigens of Death Receptors, which are members of the tumor necrosis factor (TNF) receptor Superfamily (TNFR-SF) with an intracellular death domain. The invention relates in particular to antibody molecules of the IgG1 isotype having a mutation in the Fc region that enhances clustering of IgG molecules after target binding. The invention further relates to a combination of antibody molecules binding different epitopes on one or more specific Death Receptors. The invention also relates to pharmaceutical compositions containing these molecules and the treatment of cancer using these compositions.

The present invention generally relates to antibodies that bind to HLA-A2/WT1, including bispecific antigen binding molecules e.g. for activating T cells. In addition, the present invention relates to polynucleotides encoding such antibodies, and vectors and host cells comprising such polynucleotides. The invention further relates to methods for producing the antibodies, and to methods of using them in the treatment of disease.

The present invention generally relates to antibodies that bind to GPRC5D, including bispecific antigen binding molecules e.g. for activating T cells. In addition, the present invention relates to polynucleotides encoding such antibodies, and vectors and host cells comprising such polynucleotides. The invention further relates to methods for producing the antibodies, and to methods of using them in the treatment of disease.

The present invention relates to a multispecific antibody comprising at least one domain specifically binding to a tumor-associated immune checkpoint antigen with low affinity, and at least one domain specifically binding to a tumor-associated antigen (TAA), and pharmaceutical compositions and methods of use thereof. The present invention further relates to a nucleic acid encoding said multispecific antibody, a vector comprising said nucleic acid, a host cell comprising said nucleic acid or said vector, and method of producing said multispecific antibody

In the present invention, inventors have used high throughput sequencing to identify novel mutations in ABCA1 in CM ML patient samples. Further studies in a mouse model of myelomonocytic leukemia driven by hematopoietic Tet2 deficiency have shown that these somatic mutations abrogate the tumor suppressor function of WT ABCA1, resulting in the failure to suppress canonical IL3-receptor beta signaling-driven myelopoiesis. The loss of the myelo-suppressive function of ABCA1 mutants can be overcome by raising HDL levels through overexpression of the human apolipoprotein A-1 (apoA-1) transgene. Inventors have also shown that both IL-3Rbeta blocking antibody and cyclodextrin prevented the proliferation of ABCA1 mutant-transduced Tet2 deficient BM cells similar to the effect of ABCA1-WT overexpression. Accordingly, the invention relates to a method for predicting the survival time of a subject NI suffering from CM ML comprising the step identifying at least one ABCA1 and to a method for treating said subject with HDL/ABCA recombinant (ApoA-1); cylodextrin and/or anti-IL-3Rbeta antibody.

The invention relates to the fields of immunology, oncology, and more specifically, to antibodies that can be used in the treatment of various cancers, more particularly cancers expressing CD117 antigen. These antibodies or antigen-binding molecules may be monoclonal antibodies or binding fragments thereof, they may be in particular chimeric or humanized. These antibodies may be antagonistic. The invention also relates to anticancerous or pharmaceutical compositions containing an antibody according to this invention and methods of use of these, either for laboratory work or for medical treatment.

The present disclosure provides binding proteins specific for human Wilms tumor protein 1 (WT-1) epitopes, as well as host cells that express the binding proteins. Also provided are polynucleotides that encode a binding protein and vectors that comprise a polynucleotide. Related methods and uses of the presently disclosed compositions are provided for treating diseases or disorders associated with WT-1 expression, such as various cancers.

Disclosed is an anti-IL-4R single-domain antibody and the use thereof. In particular, disclosed are a IL-4R single-domain antibody and a VHH chain thereof, a coding sequence encoding the above-mentioned single-domain antibody or the VHH chain thereof, a corresponding expression vector, host cells capable of expressing the single-domain antibody, and a method for producing the single-domain antibody. The single-domain antibody can specifically recognize human and marmoset IL-4R, but does not recognize mouse IL-4R, and the specificity is good; the single-domain antibody can effectively inhibit the proliferation of TF-1 cells and the activation of a pSTAT6 signaling pathway in cells.

Provided is an anti-PD-L1 antigen binding protein, capable of binding to primate-derived PD-L1 with a KD value of 1×10.sup.−8 M or less. The antigen binding protein can block the binding of PD-1 and CD80 to PD-L1, stimulate the secretion of cytokines in immune cells, and can inhibit tumor growth and/or tumor cell proliferation. Also provided is a fusion protein, comprising human TGFBRII or a fragment thereof and the antigen binding protein. Also provided is an application of the antigen binding protein and/or the fusion protein in the prevention and treatment of tumors or cancers.
