First ruxolitinib treatment of human alopecia areata patients

Project description:Two patients with alopecia areata were treated with systemic ruxolitinib. Skin biopsies were taken before starting treatment and 12 weeks after starting treatment. We used microarrays to assess changes in gene expression of affected skin before and after starting treatment Two patients with alopecia areata were recruited for our study. Skin biopsies of affected scalp were taken prior to starting treatment with oral ruxolinitib. Additional skin biopsies were taken 12 weeks after starting treatment. Scalp skin biopsies were taken from patients without alopecia areata for comparison. RNA was extracted, cDNA libraries were made and profiled on affymetrix microarray chips.

Extensive alopecia areata is reversed by IL-23 cytokine antagonism

Project description:Alopecia areata (AA) is a prevalent disease associated with major emotional distress, and lacks effective, safe therapeutics for patients with extensive hair loss. This is the first report of hair regrowth with specific cytokine antagonism, in three patients with extensive hair loss ranging from 40% scalp involvement to alopecia universalis. Ustekinumab, an IL-12/23p40 antagonist that is highly effective in psoriasis, showed impressive ability to induce hair regrowth, coupled with suppression of inflammatory pathways and upregulation of hair keratins. Our report suggests that extensive AA is reversible using targeted treatments, opening the door for specific cytokine antagonism for this debilitating disease. We evaluated hair regrowth in three AA patients at 20 weeks after treatment with 3 subcutaneous doses of 90mg ustekinumab given at weeks 0, 4, and 16. Skin biopsies of lesional and non-lesional scalp (when available) were taken at baseline (week 0) and at week 20. We also obtained biopsies from three healthy individuals.

Safety and Efficacy of the JAK Inhibitor Tofacitinib Citrate for Alopecia Areata and Variants

Project description:The samples include RNA from scalp biopsies before treatment and at 8 weeks of treatment with Tofacitinib Citrate 5 mg BID in patients with Alopecia Areata. 32% had a SALT score of 50% or higher and 47% had clinically significant response.

JAK3/TEC and TYK2/JAK1 inhibitors demonstrate significant improvement in scalp alopecia areata biomarkers

Project description:We present the biopsy sub-study results from the first randomized, placebo-controlled clinical trial in patients with alopecia areata (AA) with ≥50% scalp hair loss and ≤7 years since the last AA episode. In this sub-study, we evaluated the molecular responses to PF-06651600, an oral inhibitor of JAK3 and the tyrosine kinase expressed in hepatocellular carcinoma (TEC) kinase family, and PF-06700841, an oral TYK2/JAK1 inhibitor, versus placebo in nonlesional and lesional scalp biopsies of biopsy samples from patients with AA.

An Open-Label Pilot Study to Evaluate the Efficacy of Tofacitinib in Moderate to Severe Patch Type Alopecia Areata, Totalis and Universalis

Project description:This study was an open-label, clinical trial to investigate tofacitinib 5 mg to 10 mg PO twice daily in the treatment of moderate/severe alopeica areata and to identify if gene expression of the scalp correlates with clinical response. Gene expression profiling was performed on scalp biopsies of alopecia areata patients taken at baseline and up to 24 weeks of treatment of tofacitinib. We applied both naïve and supervised clustering to this dataset in order to assess two features: the overall molecular effect of tofacitinib treatment on patient samples, and the concordant molecular response of the disease. The former was assessed by an unbiased, unsupervised differential expression analysis and the latter was measured by response to previously published gene expression signatures defining AA pathology. To ensure parity of the data, for this analysis we only included patient samples that had matched pre-treatment, Tx-00, and 24 weeks of treatment, Tx-24, samples. Gene expression profiles and Alopecia Areata Disease Activity Index (ALADIN) scores correlated with clinical response.
