The invention provides an isolated and purified nucleic acid sequence encoding a chimeric antigen receptor (CAR) directed against B-cell Maturation Antigen (BCMA). The invention also provides host cells, such as T-cells or natural killer (NK) cells, expressing the CAR and methods for destroying multiple myeloma cells.

The invention provides anti-cluster of differentiation 3 (CD3) antibodies and methods of using the same.

Novel human interleukin-2 (IL-2) muteins or variants thereof are provided. In particular, provided are IL-2 muteins that have an increased binding capacity for IL-2Rβ receptor and a decreased binding capacity for IL-2Rγ.sub.c receptor, as compared to wild-type IL-2. Such IL-2 muteins are useful, for example, as IL-2 partial agonist and antagonists in applications where reduction or inhibition of one or more IL-2 and/or IL-15 functions is useful (e.g., in the treatment of graft versus host disease (GVHD) and adult T cell leukemia). Also provided are nucleic acids encoding such IL-2 muteins, methods of making such IL-2 muteins, pharmaceutical compositions that include such IL-2 muteins and methods of treatment using such pharmaceutical compositions.

The present invention provides heterocyclic compounds, the stereoisomer thereof, the enantiomer thereof, or the pharmaceutically acceptable salt, which are capable of modulating the activity of Mer receptor tyrosine kinase (MERTK). This invention also provides pharmaceutical compositions thereof, methods to prepare the said compounds, and the use of such compounds as a medicament.

The present invention is directed to MERTK inhibitory compounds with marked potency, thereby having an outstanding potential for a pharmaceutical intervention of cancer and any other diseases related to MERTK dysregulation.

Provided are a pyrimidine compound represented by Formula 1, a method of preparing the compound, and a pharmaceutical use of the compound for the prevention or treatment of cancer.

Provided are a pyrimidine compound represented by Formula 1, a method of preparing the compound, and a pharmaceutical use of the compound for the prevention or treatment of cancer.

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.

The present invention relates to a novel antibody and an antibody fragment that specifically bind to Claudin18.2 and a composition comprising the antibody or the antibody fragment. In addition, the present invention relates to a nucleic acid encoding the antibody or the antibody fragment thereof, a host cell comprising the nucleic acid, and related uses. Furthermore, the present invention relates to therapeutic and diagnostic uses of the antibody and the antibody fragment.

The present application provides antibodies including antigen-binding fragment thereof that specifically recognizing Granulocyte-Macrophage Colony Stimulating Factor Receptor (GM-CSFRα). Also provided are methods of making and using these antibodies.

Disclosed in the present disclosure are an azaheteroaryl compound, a pharmaceutically acceptable salt thereof, and a solvate thereof. The present disclosure also provides a method for preparing said compound, a composition containing said compound, and a use of said compound in the preparation of a drug for treating a disease or disorder related to the mechanism of action of an EED protein and/or a PRC2 protein complex.
