Provided herein are uses of fibroblast growth factor receptor 2 (FGFR2) inhibitors in cancer treatment, in some cases in combination with immune stimulating agents, such as inhibitors of PD-1 or PD-L1. In some embodiments, FGFR2 inhibitors may comprise FGFR2 antibodies or FGFR2 extracellular domain (ECD) polypeptides, or FGFR2 ECD fusion molecules comprising an FGFR2 ECD and a fusion partner. In some embodiments, PD-1/PD-L1 inhibitors may comprise anti-PD-1 antibodies such as antibodies that bind to PD-1 or to PD-L1 and inhibit interactions between these proteins, as well as PD-1 fusion proteins or polypeptides.

The present disclosure relates to a composition for treating or diagnosing osteoarthritis targeting activin A receptor type 2B (ACVR2B). More specifically, the present disclosure provides ACVR2B as a biomarker for diagnosing osteoarthritis because it was found that expression and activity of ACVR2B were increased at an early stage of osteoarthritis, expression of Mmp3, Mmp13, and Cox2 that induce destruction of cartilage was increased thereby, and expression of the genes was suppressed by inhibition of ACVR2B expression. In addition, since it was found that osteoarthritis was alleviated by suppressing the expression of ACVR2B, the present disclosure provides an ACVR2B expression or activity inhibitor as a therapeutic agent for osteoarthritis.

Provided are anti-FGFR2b antibodies or antigen-binding fragments thereof, isolated polynucleotides encoding the same, pharmaceutical compositions comprising the same, and the uses thereof.

Provided are anti-FGFR2b antibodies or antigen-binding fragments thereof, isolated polynucleotides encoding the same, pharmaceutical compositions comprising the same, and the uses thereof.

Methods for the detection, enumeration and analysis of circulating tumor cells expressing insulin-like growth factor-1 receptors (IGF-1R) are disclosed. These methods are useful for cancer screening and staging, development of treatment regimens, and for monitoring for treatment responses, cancer recurrence or the like. Test kits that facilitate the detection, enumeration and analysis of such circulating tumor cells are also provided.

The present invention provides a novel IGFR-like receptor and antagonists and agonists for targeting said receptor. Said antagonists and agonists are envisaged for use as a medicament, and in particular for treatment of diabetes.

The invention provides methods and compositions to detect expression of one or more biomarkers, including FGFR3, TP53, and/or EGFR, for treating, diagnosing, and providing a prognosis for cancer, e.g., bladder cancer. The invention also provides kits and articles of manufacture for use in the methods.

A composition according to an embodiment includes a first population of transformed mammalian cells with a transforming growth factor beta (TGF-β), the first population having a TGF-β expression level of 0.65 ng/10.sup.5 cells/24 hours or more, and a second population of mammalian cells which are not transformed with the transforming growth factor beta, the second population having an expression level of a thrombospondin 1 (TSP-1) expression level of 31 ng/10.sup.5 cells/24 hours or more.

The invention provides a method for the treatment of EGFRvIII-positive cancer or glioblastoma, comprising administering to a subject in need thereof an initial dose of between about 15 μg/day to about 6000 μg/day of an anti-EGFRvIII agent. Diagnostic methods for assessing EGFRvIII expression are also provided.

Provided is an application of a non-IGF1R-binding substance in the prevention and/or treatment of inflammatory diseases. Specifically, provided is use of a non-IGF1R-binding substance. The non-IGF1R-binding substance is used for preparing a composition or formulation, and the composition or formulation is used for preventing and/or treating inflammatory diseases.
