Chronic Plaque PsoriasisNCT00844363
Narrowband UVB Phototherapy in the Treatment of Psoriasis Vulgaris
A study testing NB-UVB in people with Chronic Plaque Psoriasis, run by Rockefeller University at 1 site in United States.
Trial summary
Ultra-violet light B (UVB) therapy has been used by dermatologists to treat psoriasis for decades. Only a few studies have begun to dissect the mechanism of how NB-UVB therapy causes lesion resolution. Results from this study will aid in identifying other diseases that may be treated successfully with NB-UVB. Read more about this study

Key requirements
Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.
- Ages 18 years and older
- All sexes
- No healthy volunteers
- Adult, Older adult
Who may be able to join
- Signed informed consent.
- History of chronic plaque psoriasis vulgaris, for at least six months.
- ≥10% body surface affected
- Age 18 or greater.
- Concomitant, chronic, but well-controlled medical conditions such as hypertension are allowable.
- No treatment with topical steroids for at least 2 weeks prior to entering the study
- No treatment with systemic therapies, including etretinate, UVB, PUVA, or cyclosporine, other biologics 4 weeks prior to entering the study. However, if a patient is considered to be "unstable", or would deteriorate clinically if the systemic agent is ceased (eg efalizumab), a shorter "washout" period may be considered, and would be documented in the patient charts.
- Patients who receive a stable dose of methotrexate (defined as <15mg/week for 4 months or greater) for psoriatic arthritis may be included.
Who cannot join
- Subjects who do not meet the above criteria, or who meet any of the following criteria:
- Guttate, erythrodermic, or pustular psoriasis as sole or predominant form of psoriasis.
- PHOTOSENSITIVITY: Hypersensitivity to sunlight or UVB light of any type; history of Lupus, PMLE, or any disease known to be worsened by UV light exposure
- A history of non-melanoma skin cancer may be acceptable, and in this situation, the patient will be carefully evaluated.
- Poorly controlled medical conditions of any kind.
- Any medical condition that, in the opinion of the Investigator, would jeopardize the health or well being of the patient during the course of this study.

About this study
Official title: Mechanism of Action of Narrowband UVB Phototherapy in the Treatment of Psoriasis Vulgaris
Ultra-violet light B (UVB) therapy has been used by dermatologists to treat psoriasis for decades. Only a few studies have begun to dissect the mechanism of how NB-UVB therapy causes lesion resolution. Results from this study will aid in identifying other diseases that may be treated successfully with NB-UVB. If we can identify the mechanism of action of this therapy, this may give us additional new therapeutic targets for psoriasis and other diseases. Our overall hypothesis is that UVB induces changes that will indicate a mechanism of action of this therapy in psoriasis.
- Conditions
- Chronic Plaque Psoriasis
- Being tested
- NB-UVB
What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
NB-UVBProcedure or surgery
Also called narrowband UVB phototherapy
UVB light will be administered to the entire body except for the genitals in men and eyelids, which will be shielded.NB-UVB dosing is increased by 5-20% increments in exposure time, depending on response of the patient.
| Study group | Role | What they receive |
|---|---|---|
| NB-UVB | Other | Regular, monitored NB-UVB treatment. Patients will be treated 3 times per week, and a full course of therapy is 12 weeks. NB-UVB dosing is increased by 5-20% increments in exposure time, depending on response of the patient. Receives: Procedure: NB-UVB |
What is being measured
The primary outcome is the main question the study is designed to answer.
The primary outcome is genomic analysis of lesional skin biopsies, in a time course experiment,by microarray and RT-PCR.
Measured: End of study
Secondary outcomes (4)
cell counts of leukocytes populations in skin biopsies including (but not limited to) myeloid dendritic cells (CD11c and CD1c/BDCA-1), plasmacytoid dendritic cells (BDCA-2/CD123), macrophages (CD163), and T cells (CD3, CD4, CD8, Foxp3, RORγ).
Measured: End of study
Effects of NB-UVB on NL skin will be determined by comparison of microarray analysis of NL skin biopsies throughout treatment.
Measured: End of study
To determine if there is a set of genes that can predict response, expressed in circulating PBMCs, we will perform microarray on baseline PBMCs, and compare the gene sets for responders and non-responders (discriminant analysis).
Measured: End of study
To evaluate if treatment causes an altered ratio of Th17:Tregs in the circulation and skin, we will perform intracellular cytokine staining by flow cytometry on peripheral blood and from the shave biopsy.
Measured: Before and after treatment

Where is the study taking place?
The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does the primary outcome measure?
The primary outcome is genomic analysis of lesional skin biopsies, in a time course experiment,by microarray and RT-PCR. (time frame: End of study). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 30 Jun 2011.
