摘要:
The problem to be solved by the present invention is to provide a new agent for preventing, suppressing the progression of symptoms of or the recurrence of, and/or treating hematological cancer. The inventors of the present invention have diligently studied, and focused on bispecific proteins having a first arm specifically binding to PD-1 and a second arm specifically binding to CD3 (preferably, PD-1/CD3 bispecific antibody or antibody fragment thereof) as a substance to dissolve such a problem, and found that they are useful for preventing, suppressing the progression of symptoms of or the recurrence of, and/or treating hematological cancer.
摘要:
A purpose of the present invention is to provide a method capable of more effectively prescribing an anti-human PD-1 antibody for anti-cancer therapy, a method for estimating or optimizing therapeutic efficacy thereof, and further an efficacy marker that can be used in methods thereof. The present invention enables selection of the cancer patient in whom the therapeutic efficacy of the anti-human PD-1 antibody can be expected in future, by measuring the change which is more than a certain level of several kinds of efficacy markers in blood after administering the initial dose or doses of the anti-human PD-1 antibody compared to that prior to administering the initial dose, and provides a new prescription of the anti-human PD-1 antibody for anti-cancer therapy.
摘要:
The present invention addresses the problem of providing a novel drug for the prevention of autoimmune diseases, the suppression of the progression of the symptoms of autoimmune diseases, the suppression of the recurrence of autoimmune diseases, or the treatment of autoimmune diseases. As a result of diligent investigation, the inventors of the present invention have focused on PD-1/CD3 bispecific antibodies as substances that can solve the abovementioned problem and have confirmed that said bispecific antibodies make it possible to achieve pharmaceuticals that reduce the occurrence of the adverse effects known as infusion-related reaction and cytokine release syndrome. In addition, the inventors have confirmed that said bispecific antibodies allow for interaction between PD-1 and its ligand PD-L1 and have discovered that said feature contributes to enhanced and sustained activity.
摘要:
The present invention addresses the problem of providing a novel medical agent for prevention of auto-immune diseases, inhibition of symptom progression thereof, inhibition of recurrence thereof, or treatment thereof. As a result of conducting extensive studies, the inventors of the present invention have focused attention on PD-1/CD19 bispecific antibody as a substance with the potentiality of solving the problem, and have achieved the present invention. The PD-1/CD19 bispecific antibody according to the present invention exhibits growth-inhibitory action and immunoglobulin production inhibitory action against activated B cells, and also has inhibitory action against production of cytokine from memory T cells.
摘要:
A compound represented by general formula (I):
a salt thereof, a solvate thereof, or a prodrug thereof wherein all symbols are as defined in the specification has an antagonistic activity against CXCR4 and is therefore useful as a preventive and/or therapeutic agent for CXCR4-mediated diseases, for example, inflammatory and immune diseases (for example, rheumatoid arthritis, arthritis, systemic erythematosus, retinopathy, macular degeneration, pulmonary fibrosis, transplanted organ rejection, etc.), allergic diseases, infections (for example, human immunodeficiency virus infection, acquired immunodeficiency syndrome, etc.), psychoneurotic diseases, cerebral diseases, cardiac /vascular disease(for example, arteriosclerosis, myocardial infarction, stenocardia, cerebral infarction, chronic arterial occlusive disease, etc.), metabolic diseases, and cancerous diseases (for example, cancer, cancer metastasis, etc.), a preventive and/or therapeutic agent for cancerous diseases or infections, or an agent for regeneration therapy.
摘要:
A new human polypeptide, a cDNA encoding the same and a pharmaceutical use of it. The polypeptides of the present invention possess hematopoiesis regulating activity, tissue generation/regeneration activity, activin/inhibin activity, chemotactic/chemokinetic activity, hemostatic and thrombolytic activity, and receptor/ligand activity, therefore, they are expected to be useful for prevention and/or treatment of various diseases.
摘要:
The present invention addresses the problem of providing a new drug that, with respect to autoimmune diseases or blood cancer, is for preventing, suppressing the advance of symptoms, suppressing recurrence, or treating such diseases. The inventors of the present invention conducted extensive studies, and came to focus on a PD-1/CD4 dual-specific protein as a substance that can solve the foregoing problem, leading to completion of the present invention. The PD-1/CD4 dual-specific protein according to the present invention is configured to reduce the induction of generation or release of cytokine that occurs when the protein is administered. As a result, it can be expected that infusion reaction or cytokine release syndrome that could occur upon administration of the protein is suppressed.
摘要:
The present application provides an immunosuppressive agent containing a substance that is selected from anti-CD80 antibodies and anti-PD-Ll antibodies and that promotes binding between PD-L1 and PD-1.
摘要:
The present invention addresses the problem of providing a medicinal agent for suppressing the progression and recurrence of cancer and/or for treating cancer, the medicinal agent comprising a novel active ingredient having the effect of enhancing immunity to cancer. This Allergin-1 antagonist has the effect of enhancing immunity to cancer, and can be used for suppressing the progression and recurrence of cancer and/or for treating cancer. In particular, this Allergin-1 antagonist is useful for treating cancer patients for whom the therapeutic effects of anti-tumor immunotherapeutic agent are insufficient, or useful for cancer treatments in combination with anti-cancer drugs.
