Abstract: An object of the present invention is to provide a DP receptor antagonist. A compound represented by general formula (I): (wherein all symbols are as shown in the specification) and a pharmaceutically acceptable salt thereof have DP receptor antagonistic activity and are also highly safe, and thus are useful as active ingredients of pharmaceuticals for DP receptor-mediated diseases. In addition, the compound represented by the general formula (I) and the pharmaceutically acceptable salt thereof also have good transferability to the central nervous system, and thus are particularly useful as a preventive and/or therapeutic agent for diseases associated with DP receptors present in the central nervous system among DP receptor-mediated diseases, that is, sleep-wake disorders.

Abstract: A drug or agent containing a compound having an agonistic activity to STING as an active ingredient, where the compound is represented by the following general formula (I-1): wherein all symbols represent the same meanings as described in the specification, and the compound can be used as an active ingredient of an agent for suppressing the progression of, suppressing the recurrence of and/or treating cancer or infectious disease.

Abstract: Since a compound represented by the general formula (I) (wherein definition of each group is as described in the specification), a salt thereof, a solvate thereof, or a prodrug thereof has strong and sustaining intraocular pressure lowering activity and, further, has no side effect on eyes such as ocular stimulating property (hyperemia, corneal clouding etc.), aqueous humor protein rise etc., it has high safety, and can be an excellent agent for preventing and/or treating glaucoma etc.

Abstract: The present invention is directed to the combination therapy of an anti-CD20 antibody with a BTK inhibitor for the treatment of cancer, especially to the combination therapy of CD20 expressing cancers with a type I anti-CD20 antibody or an afucosylated humanized B-Ly1 antibody and a BTK inhibitor.

Abstract: A drug or agent containing a compound having an agonistic activity to STING as an active ingredient, where the compound is represented by the following general formula (I-1): wherein all symbols represent the same meanings as described in the specification, and the compound can be used as an active ingredient of an agent for suppressing the progression of, suppressing the recurrence of and/or treating cancer or infectious disease.

Abstract: Provided are chimeric antigen receptors (CAR) specific to a selected tumor antigen. Also provided are structure designs and function profiles of provided CAR candidates.

Abstract: A compound represented by the general formula (V) wherein all the symbols are as defined in the specification, has an improved balance of the agonist activity against the S1P5 receptor relative to the S1P1 receptor, and can thus serve as a therapeutic agent for S1P5-mediated diseases such as schizophrenia and Binswanger's disease and other neurodegenerative diseases.

Abstract: The purinone derivative 6-amino-9-[(3R)-1-(2-butynoyl)-3-pyrrolidinyl]-7-(4-phenoxyphenyl)-7,9-dihydro-8H-purin-8-one hydrochloride has Btk-selective inhibitory activity and, in addition to having excellent metabolic stability, it is a compound that exhibits a high level of solubility and absorption with respect to the free base and can be crystallized, hence it can serve as a therapeutic agent for diseases involving B cells and mast cells.

Abstract: A bispecific antibody which is capable of specifically binding to PD-1 and CD3 is disclosed. The bispecific antibody is suitable for preventing, suppressing symptom progression or recurrence of, and/or treating autoimmune diseases. Also disclosed is a formulation which can reduce occurrence of adverse infusion reactions or adverse reaction called cytokine release syndrome. The bispecific antibody has the feature to allow interaction between PD-1 and PD-L1 as its ligand, contributes enhancement or duration of its effects.

Abstract: A drug is provided, which contains, as an active ingredient, a compound having ABHD6 inhibitory activity in prevention and/or treatment of a disease associated with ABHD6. A compound of formula (I-A) or a pharmaceutically acceptable salt thereof has ABHD6 inhibitory activity and therefore is useful as a pharmaceutical ingredient having potent ABHD6 inhibitory activity in the prevention and/or treatment of a disease associated with ABHD6: in which all symbols represent the same meaning as the symbols described in the specification.

Abstract: An effective cancer treatment method is disclosed. According to the cancer treatment method, a CD47 inhibitory substance, an immune checkpoint inhibitory substance (for example, an anti-PD-1 antibody), and a standard therapy (for example, a combination therapy in which Bevacizumab or Cetuximab is added to FOLFOX therapy for radically unresectable advanced or recurrent colorectal cancer, or FOLFIRINOX therapy or a dose-reduced regimen thereof for pancreatic cancer having distant metastasis) are combined. The treatment method is useful for cancer treatment.

Abstract: A compound represented by the general formula (V) wherein all the symbols are as defined in the specification, has an improved balance of the agonist activity against the S1P5 receptor relative to the S1P1 receptor, and can thus serve as a therapeutic agent for S1P5-mediated diseases such as schizophrenia and Binswanger's disease and other neurodegenerative diseases.

Abstract: A combined administration of a liposomal composition comprising Eribulin or a pharmaceutically acceptable salt thereof and a PD-1 antagonist exhibits unexpected antitumor effect.

Abstract: A therapeutic agent for solid cancers, including, as an effective component, N-{5-[(6,7-dimethoxy-4-quinolinyl)oxy]-2-pyridinyl}-2,5-dioxo-1-phenyl-1,2,5,6,7,8-hexahydro-3-quinolinecarboxamide, a pharmaceutically acceptable salt thereof, or a hydrate of the compound or the salt and to be administered in combination with osimertinib or a pharmaceutically acceptable salt thereof.
