Provided herein are improved gene therapy vectors and methods of use, in some embodiments, comprising sequences for improved expression and cellular targeting of a therapeutic protein.

The present invention provides novel antibodies and antigen binding fragments thereof that bind to human CD30. Also presented are single chain variable antibodies, chimeric antigen receptors and uses thereof. Methods of treating cancer are also disclosed.

The present invention provides therapeutic agents and compositions comprising elastin-like peptides (ELPs) and therapeutic proteins. In some embodiments, the therapeutic protein is a GLP-1 receptor agonist, insulin, or Factor VII/VIIa, including functional analogs. The present invention further provides encoding polynucleotides, as well as methods of making and using the therapeutic agents. The therapeutic agents have improvements in relation to their use as therapeutics, including, inter alia, one or more of half-life, clearance and/or persistance in the body, solubility, and bioavailability.

Provided in the present disclosure are a bifunctional protein which can bind to PD-1 (programmed death receptor-1) and TGF-β (transforming growth factor-β), the medical use of the bifunctional protein, and a preparation method therefor.

A humanized CD 19 antibody, and a chimeric antigen receptor thereof, an immune cell thereof and the use thereof are provided. The humanized CD19 antibody is based on a FMC63 chimeric antibody, which is subjected to humanization modification. A CAR-T and a dual CAR-T cell constructed based on the humanized antibody and the related use thereof are also provided. Compared with a CAR-T cell constructed by using FMC63, the CAR-T cell constructed based on the humanized antibody has higher killing effect and tumor removal ability.

A Fc-CD80 fusion protein has a CD80 extracellular domain (ECD) linked to a C-terminal of an immunoglobulin Fc domain. The Fc-CD80 fusion protein can be used for the preparation of a conjugate, the conjugate including the Fc-CD80 fusion protein as a first component, and a second component containing a second effector molecule, the second component being located at an N-terminal of the first component. In addition, a conjugate including the Fc-CD80 fusion protein, a pharmaceutical composition including the Fc-CD80 fusion protein and/or the conjugate are effective for the treatment or prevention of cancerous diseases in individuals.

The present disclosure provides methods for preventing, alleviating, or treating cytokine release resulting from administration of a VEGF inhibitor or side effects resulting from the cytokine release. To prevent, alleviate, or treat cytokine release or its side effects, the disclosure also provides combination therapies that use a lymphocyte-stimulating pharmaceutical agent, represented by an anti-T cell antigen-binding molecule, with a VEGF inhibitor. Among the anti-T cell antigen-binding molecules, for example, antibodies that recruit T cells as effector cells into tumor tissues are called T cell redirecting antibodies, and are known as means for treating tumors. On the other hand, when systemic cytokine production is stimulated by binding of antibodies to T cells, it is feared that this systemic action will lead to aberrations such as CRS. The present disclosure provides means for alleviating systemic cytokine production, and will enable safer use of anti-T cell antigen-binding molecules in tumor treatment.

Disclosed herein are anti-mesothelin antibodies and antigen-binding fragments, chimeric antigen receptors (“CARs”) having these anti-mesothelin antibodies and antigen-binding fragments (“mesothelin CARs”) and genetically modified immune effector cells having such mesothelin CARs. Polynucleotides encoding the anti-mesothelin antibodies and antigen-binding fragments and mesothelin CARs are also provided herein. Compositions comprising anti-mesothelin antibodies and antigen-binding fragments and mesothelin CARs are also provided herein. The present disclosure also relates to uses of the anti-mesothelin antibodies and antigen-binding fragments and genetically modified immune effector cells having such mesothelin CARs in cancer treatment.
