  • Publication number: 20210255183
    Abstract: The objective of the present invention is to provide a method for simply, inexpensively and accurately assessing, before administering a biological preparation, the therapeutic effect thereof (in particular whether there will be a complete response) or the improvement of symptoms in patients having rheumatoid arthritis. By using at least one serum concentration selected from the group consisting of sgp130, IP-10, sTNFRI, sTNFRII, GM-CSF, IL-1?, IL-2, IL-5, IL-6, IL-7, IL-8, IL-9, IL-10, IL-12, IL-13, IL-15, Eotaxin, VEGF, MCP-1, TNF-?, IFN-?, FGF basic, PDGF-bb, sIL-6R and MIP-1?, the therapeutic effect (improvement of symptoms and possibility of response) of an inflammatory cytokine-targeting biological preparation on a patient having rheumatoid arthritis can be predicted in any type of facility in a simple, inexpensive, and highly accurate manner before administering the biological preparation.

  • Publication number: 20210018514
    Abstract: The present invention provides a method of predicting and determining a therapeutic effect (especially whether complete remission is reached) or the level of improvement prior to administration of a biological formulation such as an anti-IL-6 agent or an anti-TNF-? agent, which is simple and cost-effective, and accurate. Sgp130, IP-10, sTNFRI, sTNFRII, GM-CSF, IL-1?, IL-2, IL-5, IL-6, IL-7, IL-8, IL-9, IL-10, IL-12, IL-13, IL-15, Eotaxin, VEGF, MCP-1, TNF-?, IFN-?, FGFbasic, PDGF-bb, sIL-6R, MIP-1? and the like can be utilized as a specific marker used in the method. Since a therapeutic effect (level of improvement in a symptom or possibility of remission) on a rheumatoid arthritis patient can be determined prior to the administration of a biological formulation using such a specific marker, rheumatoid arthritis therapy is possible at a precision that could not be achieved conventionally.
