Evaluation of Lymphocytic Infiltrate, Dendritic Cells and Cytokines Expression in Psoriatic Lesion and Normal Skin Before and After TNF Alfa Inhibitors Therapy (ELIDACE)

November 8, 2010 updated by: University of Padova

Evaluation of Lymphocytic Infiltrate, Dendritic Cells and Cytokines Expression in Psoriatic Lesion and Normal Skin Before and After Adalimumab Therapy

The efficacy of TNF alfa inhibitors in the treatment of psoriasis has been documented in many studies.

Their effect on dendritic cells has been scarcely studied. TNF- α has a central role in dendritic cell biology, both for their maturity and mobilization of peripheral tissues to secondary lymphoid organs.

The primary objectives of this study are:

  • To document absolute number, density of immune infiltrate and dendritic cells and inflammatory cytokines expression pattern (particularly IFN α and IL-32) in psoriasic lesions vs normal skin of the same patient
  • To describe changes in such cell numbers and expression patterns upon 16 weeks treatment with TNF alfa inhibitors.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Study Type

Enrollment (Anticipated)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 70 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Description

Inclusion Criteria:

  • Male and female subjects > 18 years of age, affected by moderate to severe psoriasis
  • Subject has had clinical diagnosis of psoriasis for at least 12 months, stable plaque psoriasis for at least 2 months before screening (subjects with concurrent psoriatic arthritis may be enrolled).
  • Subject is naıve to TNF-antagonist therapy and efalizumab.

  • Subjects are considered eligible according to the following tuberculosis screening criteria:

    1. Have no history of latent or active TB prior to screening;
    2. Have no signs or symptoms suggestive of active TB upon medical history and/or physical examination;
    3. Within 1 month prior to the first administration of study medication, have negative diagnostic tuberculin skin test.
  • Normal chest X-ray within 3 months prior to screening with no evidence of malignancy, infection, current or old TB.
  • Subjects' screening and baseline clinical data must be within the normal limit, including the results of medical history, physical examination and laboratory evaluation (complete blood count, serum values for liver enzymes, bilirubin, glucose, albumin, creatinine and urine analysis).
  • Willing and able to comply with the protocol requirements for the duration of the study.
  • Women of childbearing potential must be using adequate birth control measure throughout the study and for 150 days (5 months) after study completion.

Exclusion Criteria:

  • Pregnant or breast-feeding women, or women who are planning pregnancy.
  • Patients not suitable for TNF alfa inhibitors therapy

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Active Comparator: TNF alfa inhibitors
Male and female adult patients with a diagnosis of moderate to severe psoriasis (when PASI score is > 10 and BSA is > 10%). The overall study enrolment plan is 20 patients. Patients will be screened before the beginning of clinical trial by blood sample in order to exclude major contraindications to use of anti TNF α drugs.
Drug: Adalimumab, etanercept, infliximab

Adalimumab at a dose of 80 mg at week 0 (Baseline) and successively 40 mg every other week starting from week1 and up to week 15. Adalimumab will be administered as subcutaneous injection.

Etanercept at a dose of 50 mg every week, as subcutaneous injection. Infliximab at a dose of 5 mg/kg at week 0 (Baseline), then at week 2 and every 8 weeks.

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

Time Frame: 12 months
  • To document absolute number, density of immune infiltrate and dendritic cells and inflammatory cytokines expression pattern (particularly IFN α and IL-32) in psoriasic lesions vs normal skin of the same patient
