Atopic dermatitis (AD) is a chronic and highly prevalent skin disorder with multifactorial pathogenesis that includes mast cell (MC) activation as one of the main players.
Several cancer types are treated with epidermal growth factor receptor (EGFR)-targeting agents (EGFR inhibitors), but this treatment is associated with dermal toxicity in up to 90% of cases, where 80% of cases have rash, among other issues. This skin toxicity is mainly driven by elevation of Staphylococcus aureus and the proinflammatory cytokine IL-36γ. Skin keratinocytes’ cutaneous immune defense is impaired by EGFR inhibitors.
Netherton syndrome (NS) is a rare genetic disease caused by loss of functional lympho-epithelial Kazal-type-related inhibitor (LEKTI, SPINK5). It was hypothesized that small-molecule inhibitors of KLK5 could replace deficient LEKTI in NS.
Aryl hydrocarbon receptor (AhR) agonists have been reported in an Eli Lilly & Co. patent and described as potentially useful for the treatment of psoriasis, atopic dermatitis, ulcerative colitis, multiple sclerosis, Crohn’s disease, rheumatoid arthritis, graft-vs.-host disease and systemic lupus erythematosus.
Netherton syndrome (NS) is caused by mutations in the serine protease inhibitor Kazal type 5 gene (SPINK5), which encodes lympho-epithelial Kazal-type-related inhibitor (LEKTI).
JJP Biologics Sp. z o.o. has received clearance from the EMA to conduct a first-in-human study of its CD89 antagonist, JJP-1212, for IgA-mediated autoimmune and fibrotic diseases. A phase I study in healthy participants will be conducted in Poland.
It is known that transient receptor potential cation channel subfamily V member 3 (TRPV3) is crucial for the modulation of skin homeostasis by regulation of Ca2+.
Scientists at Shanghai Synergy Pharmaceutical Sciences Co. Ltd. and Zhejiang Huahai Pharmaceutical Group Co. Ltd. have synthesized non-receptor tyrosine-protein kinase TYK2 inhibitors reported to be useful for the treatment of psoriasis, inflammatory bowel disease (IBD) and lupus erythematosus.
Inhibition of OX40 is known to induce and maintain responses in moderate to severe atopic dermatitis (AD). Astria Therapeutics Inc. and Ichnos Sciences Inc. are developing STAR-0310, a YTE-modified (M252Y/S254T/T256E) monoclonal antibody targeting OX40.
A proprietary Src homology 2 (SH2) platform of integrated technologies was applied for the discovery of REX-7117 and REX-5376, two highly potent, selective and orally available SH2 domain-targeting STAT3 inhibitors.
