Vitiligo is caused by autoreactive CD8+ T cells that react against skin melanocytes, where IL-15 has been shown to activate these T cells. Innovent Biologics (Suzhou) Co. Ltd. recently presented data on their monoclonal antibody (mAb) – IBI-3013 – that targets IL-15. IBI-3013 was evaluated in vitro in immune cell expansion and CD8 T-cell activation assays, as well as in vivo in a skin inflammation model and in a graft-vs.-host disease (GVHD) model.

Interleukin-1 receptor-associated kinase 4 (IRAK-4) is a modulator of IL-1 receptor and Toll-like receptor (TLR) signaling and has emerged as a promising therapeutic target for several inflammatory diseases. Gilead Sciences Inc. and Nurix Therapeutics Inc. recently presented data generated in a preclinical murine model of AD with their IRAK-4 degrader GS-6791.

The Human Cell Atlas project has delivered a fresh tranche of data mapping fibroblasts in healthy and diseased skin and pointing to drug targets with potential in multiple diseases across a range of tissues. Using single cell sequencing and spatial genomics, a technique for showing how gene expression varies at different locations within a tissue, nine different subpopulations of fibroblasts were identified, six in healthy skin and three in disease samples.

Resvita Bio Inc. has held a pre-IND meeting with the FDA for RVB-003, its lead investigational therapy for Netherton syndrome. The FDA’s feedback gives the company a pathway to submit an IND for RVB-003 in the first half of next year, with a clinical efficacy read-out anticipated by early 2027.

Fibrobiologics Inc. has announced IND-enabling updates from its psoriasis research program demonstrating the potential of human dermal fibroblast (HDF) spheroids as a novel therapeutic approach for chronic-relapse psoriasis.

Onco3r Therapeutics BV has obtained clinical trial application (CTA) approval by the Belgian regulatory authorities for its SIK3 inhibitor O3R-5671. A first-in-human trial will be conducted in Belgium and is expected to open enrollment in the coming weeks. Final data are expected in the first half of next year and will inform subsequent patient trials across a range of autoimmune diseases, which are planned to commence next year.

The addition of photoisomerizable moieties in drugs opens the possibility of rapid and reversible light-dependent switching between an active and inactive form. Researchers from the National Institutes of Health and the University of Barcelona have developed MRS-7787, a photoswitchable adenosine A3 receptor (A3R) agonist that controls A3R through topical skin irradiation.

Neucore Bio Inc. announced it has been awarded a US$304,000 National Science Foundation Small Business Technology Transfer grant to evaluate scalable manufacturing of exosome-based gene delivery methods.
