E-GEOD-69967 - Pathologic Immune Pathways in Psoriasis are Rapidly Attenuated by Tofacitinib Treatment: A Randomized Phase 2 Study in Patients with Moderate to Severe Psoriasis
Released on 30 June 2016, last updated on 1 July 2016
Here we elucidate the molecular mechanism of tofacitinib, an oral Janus kinase inhibitor, in psoriasis. Tofacitinib exhibits a multi-tiered action, with early direct effects on keratinocytes and histological and transcriptomic improvement prior to IL-17 reduction. Twelve patients with plaque psoriasis were randomized (3:1) to receive tofacitinib 10 mg or placebo twice daily for 12 weeks. Biopsies were taken from lesional and non‑lesional skin at baseline, and from lesional skin on Day 1, Day 3, and Weeks 1, 2, 4 and 12. Biopsies were examined for psoriatic epidermal features (thickness; Ki67+ keratinocytes, keratin 16 [KRT16] mRNA expression; phosphoSTAT [pSTAT] + nuclei) and T-cell and dendritic cell (DC) subsets using immunohistochemistry. mRNA transcripts were quantified by microarray.
