Aseet ja interventiot
Osallistujaryhmä / Arm |
Interventio / Hoito |
---|---|
Active Comparator: 1 (Etanercept only)
Subjects will only be treated with etanercept.
This is given at the standard FDA approved dosage of 50 mg twice weekly x 3 months then 50 mg once weekly x 3 months.
No UVB will be given.
Sham UVB will not be used because the subjects are not blinded because they often know they are receiving sham UVB due to differences in light intensity and heat.

Etanercept is given at the standard FDA approved dosage of 50 mg twice weekly x 3 months then 50 mg once weekly x 3 months.

Kokeellinen: 2 (Etanercept + nb-UVB)
Subjects will receive etanercept. This is given at the standard FDA approved dosage of 50 mg twice weekly x 3 months then 50 mg once weekly x 3 months. In addition, for months 3-6, subjects will receive Narrow Band Ultraviolet B phototherapy three times a week for 12 weeks in addition to the etanercept maintenance dose. The safety and efficacy of the combination therapy will be evaluated by the registered phototherapy nurses at each phototherapy visit and by the study investigator at monthly visits. NB-UVB therapy will be adjusted according to the clinical judgment of the University of California San Francisco Psoriasis Treatment Center phototherapy staff. |
Etanercept is given at the standard FDA approved dosage of 50 mg twice weekly x 3 months then 50 mg once weekly x 3 months.
Muut nimet:
Narrow band (310-312 nm) ultraviolet light B phototherapy 3 times a week during Weeks 12-24.
NB-UVB therapy will be adjusted according to the clinical judgment of the University of California San Francisco Psoriasis Treatment Center phototherapy staff

---|---|---|
Psoriasis Area Severity Index. This Scale Ranges From 0-72, 0 Being no Disease, and 72 Being Most Severe. The Number of Patients Who Achieved 75% Improvement of Their Psoriasis at the End of 24 Weeks Are Indicated in the Outcomes Data Below.
Aikaikkuna: Weeks 12-24
|
Psoriasis area severity index was used to determine the number of patients in each treatment arm who had 75% improvement in their psoriasis.
This scale uses the characteristics of the psoriasis, such as body surface area, redness, thickness, and scaling, to determine the severity score.
