Provided are various aqueous formulations of the neonatal Fc receptor (FcRn) antagonist ARGX-113, including formulations useful as pharmaceutical compositions, methods for their preparation, devices comprising the various formulations, and uses thereof. In certain embodiments the formulations are suitable and useful for administration of ARGX-113 to a human subject. In certain embodiments the formulations are suitable and useful for subcutaneous administration of ARGX-113 to a human subject. The formulations can be used in the treatment of any condition that would benefit from inhibition of FcRn-mediated antibody recycling. Such conditions can include any one or more of various antibody-mediated autoimmune diseases, including, for example and without limitation, myasthenia gravis (MG) and immune thrombocytopenia (ITP).

The present invention relates to novel humanized anti-IL-4 and IL-13 antibodies and fragments thereof and novel bispecific antibodies and fragments thereof that specifically bind to IL-4 and IL-13. The invention also includes uses of the antibodies to treat or prevent IL-4 and/or IL-13 mediated diseases or disorders, including allergic asthma and dermatitis.

Methods for treating coronavirus disease 2019 (COVID-19), the disease caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infections, is described. The methods can be used to reduce the severity of outcomes related to COVID-19, such as hospitalization and ventilation. For example, treatment of a subject with a therapeutic agent that neutralizes interleukin 13 (IL-13) can result in reduced risk for mechanical ventilation in the subject. Also described are methods of predicting risk of mechanical ventilation in subjects with COVID-19.

There is described herein, a method for inducing Tc22 lineage T cells from a population of CD8+ T cells, the method comprising: a) providing a population of CD8+ T cells; b) activating the population; and c) culturing or contacting the population of CD8+ T cells with Coenzyme A.

The present invention provides compositions, systems, kits, and methods for expression of one or more biomolecules in a subject, human or non-human mammal, (e.g., at therapeutic levels for the extended periods of time required to produce therapeutic effects). In certain embodiments, compositions, systems, kits, and methods are provided that comprise a first composition comprising polycationic structures (e.g., empty cationic liposomes, cationic micelles, cationic emulsions, or cationic polymers) and a second composition comprising expression vectors (e.g., non-viral expression vectors not associated with liposomes or other carriers) encoding one or more biomolecules of interest.

The present invention relates to systems and methods for the treatment of conditions of chronic inflammation, such as periodontitis, that includes the use of sustained release microparticles to locally deliver a compound or agent to reduce inflammation of tissue, such as periodontal tissue, and/or inflammatory mediators. The microparticles are loaded with a compound or agent selected from the group consisting of C-C motif chemokine ligand 2 (CCL2), interleukin 4 (IL-4), anti-interleukin 17 (IL17 antibody), and mixtures or blends thereof

The present technology relates generally to dry powder formulations comprising leucine and trileucine in specific ratios that are suitable for pulmonary delivery. Also provided are methods of preparing the dry powder formulations, and methods of administration and treatment using the dry powder formulations.

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.

Methods and compositions for treating or preventing C. difficile infections, particularly recurring C. difficile infections are described. The compositions for use in treating C. difficile include at least one agent that enhances a biological activity of interleukin-13 (IL-13), such as a recombinant IL-13 peptide or an agent that neutralizes the interleukin-13 (IL-13) decoy receptor, interleukin-13 receptor subunit alpha-2 (IL-13Ra2). Additionally or alternatively, the compositions can include a interleukin-4 (IL-4) peptide. The methods can result in more rapid recovery from CDI and decreased weight loss, e.g., than treatment without the neutralizing agent.
