A Study to Assess the Effect of Ustekinumab (Stelara®) and Etanercept (Enbrel®) in Participants With Moderate to Severe Psoriasis (MK-0000-206)

January 13, 2015 updated by: Merck Sharp & Dohme LLC

A Clinical Trial to Assess the Effects of Ustekinumab and Etanercept on Skin and Blood Biomarkers of Psoriasis in Patients With Moderate to Severe Disease

This is a two-part study. The purpose of the pilot study (Part 1) is to optimize the acquisition, handling and shipping procedure for skin biopsies obtained from participants with plaque psoriasis. No treatment will be administered. Part 2 will include 2 cohorts. In Cohort 1, the effects of 16 weeks of treatment with either ustekinumab or etanercept on biomarkers in lesional skin in participants with moderate to severe psoriasis will be evaluated. In Cohort 2, biomarkers of lesional skin from participants with moderate to severe psoriasis who are not treated with biologic therapy will be evaluated over 16 weeks. The primary hypothesis is that treatment with ustekinumab reduces messenger RNA (mRNA) expression of genes in the interleukin 12 (IL-12) pathway that are modulated by interferon gamma (IFN-γ).

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Change From Baseline in Composite Gene Expression Score Based on IL-12 Pathway Related Interferon Gamma (IFN-γ)-Modulated Genes in Psoriatic Lesions of Participants Treated With Ustekinumab
Time Frame: Baseline and Weeks 1, 2, 4, and 16
Skin biopsies were collected from participants at baseline and after treatment with ustekinumab for 1,2,4 and 16 weeks. The expression of messenger RNA (mRNA) from three pre-defined IL-12 pathway related genes, modulated by interferon gamma (IFN-γ), namely IFN-γ, inducible nitric oxide synthase(iNOS) and CXC motif chemokine 10(CXCL10) was quantitated by real-time polymerase chain reaction (qPCR), with the data normalized by the delta-delta Ct method. The expression score for each gene, showing the percentage difference from baseline, was calculated as follows : [(baseline - post baseline)/baseline] x 100. Composite gene expression scores were derived for each individual by summing the expression scores of the individual genes. Positive composite scores denote a decrease from baseline in gene expression.
Baseline and Weeks 1, 2, 4, and 16

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Change From Baseline in Composite Gene Expression Score Based on Interleukin 23 (IL-23) Pathway Related Genes in Psoriatic Lesions of Participants Treated With Ustekinumab
Time Frame: Baseline and Weeks 1, 2, 4, and 16
Skin biopsies were collected from participants at baseline and after treatment with ustekinumab for 1,2,4 and 16 weeks. The mRNA expression of eight pre-defined IL-23 pathway related genes, namely beta 4 defensin (DEFB4), CXC motif chemokine 8 (CXCL8), Interleukins 17A, 17F, 20, 22, 23A (IL-17, IL-17F, IL-20, IL-22, IL-23A) and cyclic AMP dependent protein kinase (CAMP) was quantitated by qPCR, with the data normalized by the delta-delta Ct method. The expression score for each gene, showing the percentage difference from baseline, was calculated as follows : [(baseline - post baseline)/baseline] x 100. Composite gene expression scores were derived for each individual by summing the expression scores of the individual genes. Positive composite scores denote a reduction from baseline in gene expression.
Baseline and Weeks 1, 2, 4, and 16
Change From Baseline in Gene Expression Score for Interleukin 17 (IL-17) in Psoriatic Lesions of Participants Treated With Etanercept
Time Frame: Baseline and Weeks 1, 2, 4, and 16
Participants had skin biopsies performed at baseline and after treatment with etanercept for 1,2,4 and 16 weeks. The expression of IL-17 mRNA was quantitated by qPCR, with the data normalized by the delta-delta Ct method. The expression score, showing the percentage difference from baseline, was calculated as follows : [(baseline - post baseline)/baseline] x 100.
