Methods for suppressing IgE-mediated anaphylaxis are provided herein, which include administering to a person in need thereof a combination of at least two therapeutic agents selected from the group consisting of an antihistamine, one or more beta-adrenergic agonists, and one or more tyrosine kinase antagonists. Also provided herein are methods of suppressing IgE-mediated anaphylaxis associated with immunotherapeutic desensitization of a subject, and pharmaceutical compositions for suppressing IgE-mediated anaphylaxis.

Provided herein are improved methods for diagnosing allergy in a subject using designed ankyrin repeat proteins (“DARPins”), and kits for use in such methods. Also provided herein are novel DARPins and methods of use thereof.

VH domain, in which: (i) the amino acid residue at position 112 is one of K or Q; and/or (ii) the amino acid residue at position 89 is T; and/or (iii) the amino acid residue at position 89 is L and the amino acid residue at position 110 is one of K or Q; and (iv) in each of cases (i) to (iii), the amino acid at position 11 is preferably V; and in which said VH domain contains a C-terminal extension (X)n, in which n is 1 to 10, preferably 1 to 5, such as 1, 2, 3, 4 or 5 (and preferably 1 or 2, such as 1); and each X is an (preferably naturally occurring) amino acid residue that is independently chosen, and preferably independently chosen from the group consisting of alanine (A), glycine (G), valine (V), leucine (L) or isoleucine (I).

The present invention relates to immunoglobulins that bind IgE and FcγRIIb with high affinity, said compositions being capable of inhibiting cells that express membrane-anchored IgE. Such compositions are useful for treating IgE-mediated disorders, including allergies and asthma.

Disclosed herein are reduced viscosity liquid formulations comprising a protein and an excipient compounds. Further disclosed are methods of reducing the viscosity of a liquid formulation comprising a protein, methods of treatment, and methods of improving protein processing.

The present disclosure relates to methods for modifying the course of a disease or disorder involving IgE, in particular an IgE mediated food allergy to one or more allergens, in subjects having such disease or condition.

Disclosed herein are formulations with improved stability or reduced viscosity that comprise a therapeutic protein and a lyo-enhancing excipient, wherein the improved stability formulation is characterized by improved stability in comparison to a control formulation otherwise identical to the stability-enhanced formulation but lacking the lyo-enhancing excipient, and the reduced viscosity formulation is characterized by reduced viscosity in comparison to a control formulation otherwise identical to the reduced viscosity formulation but lacking the lyo-enhancing excipient. Further disclosed herein are methods of improving stability of therapeutic formulations, reducing viscosity of therapeutic formulations, or improving parameters of lyophilization processes.

Disclosed herein are anti-IgE antibodies having low binding affinity to human IgE and compositions and methods thereof. In some embodiments, the present invention provides a composition comprising one or more humanized low affinity anti-IgE antibodies (hLAAIGEs) and a pharmaceutically acceptable carrier. In some embodiments, the present invention provides a method of treating a subject for an IgE-mediated disorder, which comprises administering to the subject one or more hLAAIGEs or a composition thereof. In some embodiments, the IgE-mediated disorder is an allergic reaction.

The present invention discloses the generation of novel variants of Fc domains, including those found in antibodies, Fc fusions, and immuno-adhesions, which have an increased binding to the FcRn receptor and/or increased serum half-life.

Methods for treating a disorder associated with immunoglobulin E (IgE) in a subject with antibodies capable of binding to the Cεmx domain of a membrane-bound IgE. The subject can be administered with at least two doses of the antibody, the two doses being at least three months apart.
