An implantable or injectable scaffold comprising immunostimulatory compounds and a suppressor of regulatory T cell induction is provided for use in immunotherapy treatments, including the treatment of cancers and other tumors, in particular solid tumors including inoperable tumors, as well as for other applications of immune enhancement and/or suppression.

Disclosed herein are fusion proteins for use in treating an inflammatory or immune disorder and methods of use. In some examples, the fusion proteins include an anchor domain and a therapeutic polypeptide. In some examples, the fusion proteins and methods herein can be used to treat inflammatory or immune disorders.

The present invention provide anti-human IL6 monoclonal antibodies, amino acid sequences of the variable region of the heavy chain and of the variable region of the light chain thereof, and encoding nucleotide sequences thereof. The present invention also provides a method for preparing the anti-human IL6 monoclonal antibodies and use of the anti-human IL6 monoclonal antibodies in the preparation of an antitumor drug. The present anti-human IL6 monoclonal antibodies can inhibit cell proliferation by blocking an IL6 signal pathway, thereby achieving the purpose of tumor immunotherapy.

The current disclosure provides polypeptide, nucleic acid, compositions, and methods for treating or preventing CRS in patients in need thereof, particularly for those receiving an immunotherapy, such as a cancer immunotherapy, that may provoke a CRS response. Accordingly, aspects of the disclosure relate to a chimeric binding polypeptides comprising a heavy chain variable region comprising CDR1, CDR2, and CDR3 attached by a heterologous linker to a light chain variable region comprising CDR4, CDR5, and CDR6.

The disclosure provides methods of treating a malignancy comprising administering an effective dose of an immune cell therapy (e.g., a chimeric antigen receptor genetically modified T cell immunotherapy) and methods for manufacturing such immunotherapy. Some aspects of the disclosure relate to methods of determining objective response of a patient to an immune cell immunotherapy based on the levels of patient and product attributes prior to and after administration of the immunotherapy to the patient.

The disclosure provides a population of polypeptide variants based on a common scaffold, each polypeptide in the population comprising the scaffold amino acid sequence X.sub.sc1AELDX.sub.sc2X.sub.sc3GVG AXXIKXIX.sub.sc4XA XXVEXVQXXK QXILAX. The disclosure also provides methods for selecting and identifying polypeptides from the population, as well as such polypeptides themselves.

Administration regimens for therapeutic proteins (e.g., T cell-activating bispecific antibodies) that mitigate cytokine release syndrome and infusion-related reaction are disclosed. The methods employ initial fractional dosing with optional administration of additional agents such as steroids or cytokine antagonists that are discontinued with maximal weekly dosing over the course of the dosing regimen.

The present disclosure provides a novel type of drug for treating a subject suffering from an inflammatory and/or autoimmune disease, and specifically rheumatoid arthritis. Specifically, the disclosure provides polypeptides comprising at least three immunoglobulin single variable domains (ISVDs), characterized in that at least one ISVD binds to TNF-α and at least two ISVDs bind to IL-6. The present disclosure also provides nucleic acids, vectors and compositions.

Formulations containing pH-sensitive nanoparticles for the enteric delivery of therapeutic agents are provided. The nanoparticles include a pH-sensitive polymer that protects the therapeutic agent against degradation in the stomach and allows it to be released in the small intestine or colon. The nanoparticle formulation is particularly effective at protecting sensitive biotherapeutic agents from degradation when administered orally, and makes it possible to avoid administration of such agents by injection. Also provided are methods for producing the formulations, as well as methods of treating diseases employing the formulations.

Provided are methods of treating a FGF19-mediated cancer or tumor in a subject by administering to the subject an anti-IL-6 antibody or an anti-IL-6 receptor antibody or an inhibitor of STAT3/JAK signaling pathway, and pharmaceutical compositions relating thereto.
