Therapeutic immunoglobulin G4 for improved bioanalytical and bioprocessing properties
In certain embodiments, the disclosure provides an IgG4 antibody comprising a heavy chain and a light chain, wherein the heavy chain comprises: (a) a modified IgG4 CH1 region having a substitution of the lysine residue at position 196; or (b) a modified IgG4 hinge region having a substitution of the serine residue at position 217, the glycine residue at position 220, the proline residue at position 224 or the proline residue at position 225. Preferably, the IgG4 antibody further comprises a substitution of the serine residue at position 228 in the heavy chain hinge region.

METHOD TO INCREASE ANTIBODY YIELD DURING ION EXCHANGE CHROMATOGRAPHY
The present invention relates to a method for increasing antibody yield during antibody purification from a sample by ion exchange chromatography in flow-through mode by pre-conditioning the sample with Tris without the use of NaCl to adjust the conductivity.
ELUATE COLLECTION DURING ANTIBODY CHROMATOGRAPHY
The present invention relates to an improved method for peak fractionation and eluate collection during chromatography for purification of a human therapeutic antibody.
TREATMENT OF FIBROSIS WITH COMBINED BLOCKADE OF IL-6 AND IMMUNE CHECKPOINT
Compositions and methods are provided for reducing fibrosis in a mammal by administering a therapeutic dose of a combination of agents to block interleukin-6 (IL-6), and an immune checkpoint inhibitor; wherein the checkpoint inhibitor comprising an agent that blocks programmed cell death protein 1 (PD1), blocks PD1 ligand 1 (PDL1), or blocks CD47/SIRPa pathway.
TREATMENT OF PERIODONTITIS VIA INDUCTION OF M2 MACROPHAGES
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
Methods of treating psoriasis using IL-17 antagonists
The disclosure relates to novel regimens for treating psoriasis, which employ a therapeutically effective amount of an IL-17 antagonist, e.g., an IL-17 binding molecule, e.g., an IL-17 antibody, such as the secukinumab antibody, or an IL-17 receptor binding molecule, e.g., an IL-17 receptor antibody.
Liquid pharmaceutical composition
The present invention relates to novel liquid pharmaceutical compositions of adalimumab, which include adalimumab or a biosimilar thereof, arginine and/or methionine, and a small polyol stabiliser such as glycerol. Such a combination of components furnishes formulations having a stability (e.g. on storage and when exposed to stress) which is comparable to or an improvement upon those known in the art, and with fewer ingredients. Such advances will help adalimumab treatments to become more widely available at lower cost, and prolong the viability of pre-loaded delivery devices (e.g. pre-filled syringes) to reduce unnecessary waste of the drug.

COMPOSITIONS AND METHODS OF TREATING THROMBOSIS
A method of inhibiting hypercoagulation and/or thrombosis in a subject having or at risk of hypercoagulation or thrombosis includes administering to the subject an amount of a composition effective to inhibit MRP-8/14 and/or MRP-14 binding to platelet CD36 and inhibit hypercoagulation and/or thrombosis in the subject.
