Combination of peripheral blood gene expression profiles and clinical parameters predicts response for tocilizumab (anti-IL6) treatment in rheumatoid arthritis

ABSTRACT: We used microarrays to identify markers predicting responder status in tocilizumab treatment in rheumatoid arthritis in 13 patients at week 0 and week 4 of treatment. Peripheral blood samples were obtained at week 0 and week 4 of tocilizumab treatment and global gene expression profiling identified markers of responder status.

Distinct, non-overlapping gene panels of peripheral blood gene expression predict response to infliximab therapy in rheumatoid arthritis and Crohn's disease

Project description:We used microarrays to identify markers predicting responder status in infliximab treatment in 19 rheumatoid arthritis and 20 Crohn's disease patients at week 0 and week 2 of treatment. Peripheral blood samples were obtained at week 0 and week 2 of inxliximab treatment and global gene expression profiling identified markers of responder status.

Short Term Immune Response to IL6 inhibition (Tocilizumab)

Project description:we examined the effects of IL6 inhibition treatment on biologic molecular pathways in a 59 year old patient well diagnosed with RA with inadequate response to DMARD thus treated with tocilizumab. To assess the immunological outcome we used quantitative proteome analysis to evaluate changes in the proteome profile of different biologic pathways in leukocyte cell populations important to RA pathogenesis isolated by positive enrichment of CD14, CD4, CD8, CD19, and CD56.

Effects of tocilizumab versus methotrexate therapy on gene expression profiles in the early rheumatoid arthrtis synovium

Project description:Rheumatoid arthritis (RA) is a chronic, systemic autoimmune inflammatory disease that is characterized by the presence of inflammatory cytokines, including interleukin-6 (IL-6). Here, we investigated the global molecular effects of Tocilizumab, an approved humanized anti-IL6 Receptor antibody, versus Methotrexate therapy, in synovial biopsy samples collected prospectively in early RA before and 12 weeks after administration of the drug. The results were compared with our previous data, generated in prospective cohorts of Adalimumab- and Rituximab-treated (Methotrexate- and anti-TNF-resistant, respectively) RA patients. We found that Tocilizumab induces a significant down-regulation of genes included in specific pathways: cytokines & chemokines (e.g. IL-6, IL-7, IL-22, CCL8, CCL11, CCL13, CCL19, CCL20), and T cell activation. By contrast, Tocilizumab induces a significant up-regulation of genes associated with healing processes. These effects are significantly more pronounced as compared to Methotrexate, Rituximab, or Adalimumab therapies. By opposition to the effects of Adalimumab, Tocilizumab therapy does not induce a decreased expression of genes involved in cell proliferation. Paired synovial biopsy samples were obtained from the affected knee of early RA patients before and 12 weeks after initiation of Tocilizumab (n=12) or Methotrexate (n=8) therapy. SDAI remission criteria were computed prospectively before, 3 months and 6 months after administration of the drugs and patientsM-bM-^@M-^Y responses were defined according to their SDAI remission status at 6 months. Gene expression studies were performed using GeneChip Human Genome U133 Plus 2.0 arrays.

Single-cell RNA sequencing of Tocilizumab-treated peripheral blood mononuclear cells as an in vitro model of inflammation

Project description:COVID-19 has posed a significant threat to global health. Early data has revealed that IL-6, a key regulatory cytokine, plays an important role in the cytokine storm of COVID-19. Multiple trials are therefore looking at the effects of Tocilizumab, an IL-6 receptor antibody that inhibits IL-6 activity, on treatment of COVID-19, with promising findings. As part of a clinical trial looking at the effects of Tocilizumab treatment on kidney transplant recipients with subclinical rejection, we performed single-cell RNA sequencing of comparing stimulated PBMCs before and after Tocilizumab treatment. We leveraged this data to create an in vitro cytokine storm model, to better understand the effects of Tocilizumab in the presence of inflammation. Tocilizumab-treated cells had reduced expression of inflammatory-mediated genes and biologic pathways, particularly amongst monocytes. These results support the hypothesis that Tocilizumab may hinder the cytokine storm of COVID-19, through a demonstration of biologic impact at the single-cell level.

Tocilizumab treatment leads to early resolution of myeloid dysfunction and lymphopenia in patients hospitalized with COVID-19

Project description:Tocilizumab, an anti-interleukin-6 receptor inhibitor, is recommended in global treatment guidelines for patients hospitalized with severe COVID-19. Using proteomic and transcriptomic analysis, we characterized the immune profile and identified cellular and molecular pathways directly modified by tocilizumab in peripheral blood samples collected from patients enrolled in the COVACTA study, a phase 3, randomized, double-blind, placebo-controlled trial, to assess the efficacy and safety of tocilizumab in hospitalized patients with severe COVID-19 pneumonia. We identified factors predicting disease severity and clinical outcomes, including markers of inflammation, lymphopenia, myeloid dysfunction, and organ injury. Proteomic analysis confirmed a pharmacodynamic effect for tocilizumab. Transcriptomic analysis revealed that tocilizumab treatment leads to faster resolution of lymphopenia and myeloid dysfunction associated with severe COVID-19 thus supporting an underlying anti-inflammatory mechanism of action for the beneficial effects of tocilizumab in patients hospitalized with COVID-19.

Effects of choline intake and pregnancy on peripheral blood leukocyte gene expression

Project description:To explore the influence of choline intake and pregnancy status on gene expression, we employed whole genome microarray expression profiling to identify genes that were differentially expressed between two choline intake groups and between pregnant and non-pregnant women. Healthy third trimester (gestational week 26-29) pregnant women and non-pregnant women were randomized to a 12-week choline controlled feeding study. The participants consumed either 480 (n=6 pregnant and n=5 non-pregnant) or 930 (n=6 pregnant and n=5 non-pregnant) mg choline/d. Fasting peripheral blood leukocyte samples were collected at week 0 and week 12 to extract RNA and perform the arrays. Healthy third trimester (gestational week 26-29) pregnant women and non-pregnant women were randomized to a 12-week choline controlled feeding study. The participants consumed either 480 (n=6 pregnant and n=5 non-pregnant) or 930 (n=6 pregnant and n=5 non-pregnant) mg choline/d for 12 weeks. Fasting (10-h) peripheral blood leukocyte gene expression were measured at week 0 and week 12.

Phase I Clinical trial of personalized peptide vaccine in combination with humanized anti-IL6 receptor monoclonal antibody for refractory colorectal cancer patients

Project description:Interventions: Anti-IL6 receptor antibody [Actemra (tocilizumab), Chugai Pharmaceutical Co; 0.5mg/kg (n=6), 2mg/kg (n=6), or 8mg/kg (n=6)] is intravenously administrated. After three days, a maximum of 4 peptides (3 mg/each peptide), which are selected based on the results of HLA typing and peptide-specific IgG titers, are subcutaneously administrated with incomplete Freund’s adjuvant (Montanide ISA51, Seppic)once a week for consecutive 6 weeks. During the treatment, safety is evaluated.The dose of anti-IL6 receptor antibody is escalated, if the safty is confirmed in 6 independent patients at the same dose. Primary outcome(s): Safety (adverse events) of personalized peptide vaccine in combination with anti-IL6 receptor antibody. Study Design: Single arm Non-randomized
