This disclosure features methods and compositions for treating inflammatory disorders or conditions that arise in a tissue originating from the endoderm using an immune modulator.

The invention pertains to antibodies or other antigen binding proteins targeting the CD276 antigen, also known as B7-H3. The invention provides an improved set of antibodies which bind at new positions within the CD276 antigen and are of particular use as therapeutics in the treatment of CD276 positive cancer. Further the invention provides antibody conjugate and bispecific antibodies which were developed on basis of the novel anti-CD276 antibodies of the invention. Furthermore, the invention discloses the therapeutic use of the antibodies and other modulators in the treatment of CD276 positive cancer. Finally, the nucleic acid constructs encoding the molecules of the invention, recombinant cells expressing them, as well as particular uses and methods are provided.

Anti-Siglec-9 antibody molecules or binding fragments thereof are disclosed. These Anti-Siglec-9 antibody molecules or binding fragments can be used to treat cancer, acute or chronic hepatitis B.

Provided are methods of treating cancer with non-competitive, agonist anti-OX40 antibodies and antigen-binding fragments thereof that bind to human OX40 (ACT35, CD134, or TNFRSF4), in combination with a PI3K (phosphatidylinositol-4,5-bis-phosphate 3-kinase) delta inhibitor.

Provided are bispecific antibodies against CD3 and EGFR, the nucleic acid molecules encoding the antibodies, expression vectors and host cells used for the expression of the antibodies. The antibodies provide a potent agent for the treatment of CD3-related and/or EGFR-related diseases via modulating immune functions.

The invention provides an immunoconjugate comprising an antibody construct which includes an antigen binding domain and an Fc domain, an adjuvant moiety, and a linker, wherein each adjuvant moiety is covalently bonded to the antibody via the linker. Methods for treating cancer with the immunoconjugates of the invention are also described.

Methods for treating cancer with the immunoconjugates of the invention are also described.

The present invention provides compositions of CD180 targeting molecules coupled to heterologous antigens, and their use in treating and/or limiting disease.

The present disclosure describes combination therapies comprising an antagonist of Programmed Death 1 receptor (PD-1) and a multi-RTK inhibitor, and the use of the combination therapies for the treatment of cancer. The multi-RTK inhibitor may be represented by Formula (I): ##STR00001## wherein R.sup.1 is C.sub.1-6 alkyl or C.sub.3-8 cycloalkyl, R.sup.2 is a hydrogen atom or C.sub.1-6 alkoxy, and R.sup.3 is a hydrogen atom or a halogen atom. A tumor therapeutic agent is disclosed that combines a compound or pharmaceutically acceptable salt thereof represented by Formula I and an anti-PD-1 antibody.

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 inhibits expression or activity of DUX4. In some embodiments, the molecular payload is an oligonucleotide, such as an antisense oligonucleotide or RNAi oligonucleotide.
