The invention is directed to a method for treating an inflammatory disorder of the lower airways in a human subject in need thereof, comprising administering an effective amount of a recombinant human IL-1 receptor antagonist (rhIL-IRa) directly to the lower airways in the human subject; wherein the inflammatory disorder is caused by a coronavirus infection.

The present disclosures is related to IL2 muteins and their uses in the treatment of human disease.

Provided is a pharmaceutical formulation comprising a modified IL-7 protein. More particularly, it comprises (a) a modified IL-7 fusion protein; (b) a basal buffer with a concentration of 10 to 50 mM; (c) a sugar with a concentration of 2.5 to 5 w/v %; and (d) a surfactant with a concentration of 0.05 to 6 w/v %. Such pharmaceutical formulation of a modified IL-7 fusion protein does not show aggregates formation, but shows protective effects on proteins under stress conditions such as oxidation or agitation, and thus can effectively be used for the treatment of a patient.

The invention described herein is directed to compositions and methods for inducing red blood cell (RBC) differentiation. Additionally, provided herein are methods of treating a subject in need thereof by administering the induced RBC described herein.

The application relates to a method of treating cancer or a tumor comprising administering a dual cytokine fusion protein composition, pharmaceutical composition, and/or formulation thereof comprising IL-10 or IL-10 variant molecules fused to a single chain variable fragment scaffolding system and a second cytokine, where the second cytokine is linked in the hinge region of the scFv, in combination with an adaptive cell therapies or bispecific T cell engagers.

The present invention relates to a heterodimeric Fc-fused protein comprising a first Fc region and a second Fc region of an immunoglobulin Fc pair and a physiologically active protein composed of two or more different subunits, wherein one or more subunits of the physiologically active protein are linked separately to one or more ends of the N-terminus or C-terminus of the first Fc region and/or the second Fc region, and CH3 domains of the first Fc region and the second Fc region are mutated so as to promote the heterodimeric Fc formation. Moreover, the present invention relates to a pharmaceutical composition comprising the heterodimeric Fc-fused protein. The heterodimeric Fc-fused protein according to the present invention has an advantage in that it can retain the activity of a naturally occurring physiologically active protein whose two or more different subunits exhibit physiological activity by forming a protein complex, because the physiologically active protein can be linked to an immunoglobulin heterodimeric Fc such that the naturally occurring form and structure of the fused protein thereof can be maintained. When the heterodimeric Fc-fused protein according to the present invention is used, there is an advantage in that the in vivo half-life of the physiologically active protein contained in the heterodimeric Fc-fused protein can be significantly increased due to the Fc-mediated long half-life such that various physiological activities thereof in vivo can be long-lasting.

The present disclosure relates to expansion and activation of T cells. In an aspect, the present disclosure relates to expansion and activation of γδ T cells that may be used for transgene expression. In another aspect, the disclosure relates to expansion and activation of γδ T cells while depleting α- and/or β-TCR positive cells. T cell populations comprising expanded γδ T cell and depleted or reduced α- and/or β-TCR positive cells are also provided for by the instant disclosure. The disclosure further provides for methods of using the disclosed T cell populations.

Provided herein are IL-21 muteins and fusion proteins comprising the same for use in methods of treating a disease. Related conjugates, nucleic acids, vectors, host cells, pharmaceutical compositions and kits are also provided herein. Methods of making the IL-21 muteins and fusion proteins comprising the same, as well as methods of treating a subject in need thereof, are provided by the present disclosure. Further provided are PD-1 antigen-binding proteins.

Human interleukin-2 (IL-2) muteins or variants thereof are provided. In particular, provided are IL-2 muteins that have an increased binding capacity for IL-2Rβ receptor as compared to wild-type IL-2 for use in combination therapies with anti-PD-1 antibodies for the treatment of cancer. Also provided are pharmaceutical compositions that include such anti-PD-1 antibodies and the disclosed IL-2 muteins.
