Abstract: The present disclosure relates to hIL2 orthogonal ligands (“IL2 orthologs”) that specifically and selectively bind to the extracellular domain (ECD) a transmembrane polypeptide comprising of a modified hCD122 polypeptide. The binding of the hIL2 ortholog to the modified hCD122 polypeptide participates in the transduction pathway of intracellular signaling resulting in a biological activity of the native intracellular signaling patterns associated with hIL2 binding to either the intermediate or high affinity hIL2 receptor but which exhibits selectivity to an engineered cell expressing an hCD122 orthogonal receptor. The hIL2 orthologs of the present invention exhibit significantly reduced binding relative to their binding to the extracellular domain of wild type hCD122, either alone or when hCD122 is present in the form of an endogenous high or intermediate affinity hIL2 receptors.

Abstract: The present disclosure provides compositions and methods of use involving binding proteins, e.g., antibodies and antigen-binding fragments thereof, that bind to the matrix metalloproteinase-9 (MMP9) protein (MMP9 is also known as gelatinase-B), such as where the binding proteins comprise an immunoglobulin (Ig) heavy chain (or functional fragment thereof) and an Ig light chain (or functional fragment thereof).

Abstract: The disclosure relates to methods to control trace metals during production of anti-CD38 antibodies, drug substances and drug products generated using the methods, and uses of the generated drug substances and drug products.

Abstract: The present disclosure provides a cytokine-based bioactivatable drug construct (“VitoKine”) platform that aims to reduce systemic mechanism-based toxicities and lead to broader therapeutic utility for proteins and cytokines such as IL-15 and IL-2 for the treatment of cancer, autoimmune diseases, inflammatory diseases, viral infection, transplantation and various other disorders. The novel VitoKine constructs of the present invention comprise: 1) a tissue or disease site targeting moiety D1 domain (“D1”), 2) a bioactivatable moiety D2 domain (“D2”), and a concealing moiety D3 domain (“D3”). Importantly, because the “active moiety” of the VitoKine construct will remain inert until activated locally by proteases that are upregulated in diseased tissues, this will limit binding of the active moiety to the receptors or to the targets in the peripheral or on the cell-surface of non-diseased cells and tissue to prevent over-activation of the pathway and reduce undesirable “on-target” “off tissue” toxicities.

Abstract: The present disclosure relates to modified IL-2 polypeptides, compositions comprising modified IL-2 polypeptides, methods of making the same, and methods of using the modified IL-2 polypeptides for treatment of diseases. In one aspect, the disclosure relates to the treatment of cancer using the modified IL-2 polypeptides. In some embodiments, the disclosed IL-2 polypeptides exhibit preferential binding characteristics to IL-2 receptor ?? complex (IL-2R?) over IL-2 receptor ??? complex (IL-2R?). In some embodiments, the molecular weight distribution of the modified IL-2 polypeptides is monodispersed.

Abstract: The present application concerns methods for treating an IL-6-mediated disorder such as rheumatoid arthritis (RA), juvenile idiopathic arthritis (JIA), systemic JIA (sJIA), polyarticular course JIA (pcJIA), systemic sclerosis, or giant cell arteritis (GCA), with subcutaneously administered antibody that binds interleukin-6 receptor (anti-IL-6R antibody). In particular, it relates to identification of a fixed dose of anti-IL-6R antibody, e.g. tocilizumab, which is safe and effective for subcutaneous administration in patients with IL-6-mediated disorders. In addition, formulations and devices useful for subcutaneous administration of an anti-IL-6R antibody are disclosed.

Abstract: The present invention provides a combination therapy for treating a tumor in a subject. The combination comprises two elements. The first is a polypeptide construct comprising an attenuated Type 1 interferon (IFN) linked to an antibody which binds to a cell surface-associated antigen expressed on the tumour cell and comprising a functional Fc region. The second is a CD47 antagonist which inhibits the interaction CD47 with the SIRP? receptor.
