Safety and Efficacy of Combining nbUVB to Etanercept in Patients

1. september 2011 opdateret af: Innovaderm Research Inc.

A Randomized Study Combining Etanercept and Short Courses of Narrow-Band UVB in Patients With Psoriasis Vulgaris

This study will provide data on the addition of narrow band ultra violet B (nbUVB) phototherapy to participants who have not shown an excellent response to three months of etanercept.

Detaljeret beskrivelse

All participants will receive etanercept 50 mg twice a week for 12 weeks. Participants who reach PASI-90 at Day 84 will be discontinued from the study (they can continue receiving commercial etanercept outside the study). Participants remaining in the study at Day 84 will decrease etanercept to 50 mg weekly for another 12 weeks.

Participants who do not attain a 90 percent reduction in PASI from baseline (PASI-90) after 12 weeks will be randomized (1:1) to receive either etanercept alone or etanercept with short courses of narrow band ultra violet B (nbUVB)phototherapy. Participants randomized to the nbUVB group will receive nbUVB treatments three times a weeks for at least four weeks. At every planned study visit after Day 84, nbUVB treatment will be discontinued in participants who reach PASI-90. nbUVB phototherapy will be re-initiated for another four weeks at the subsequent planned study visit if they lose their PASI-90 response.

Efficacy will be evaluated with PASI, BSA and PGA by a blinded evaluator at Days 0, 28, 84, 112, 140 and 168. The effect of the treatment on quality of life will be evaluated using the DLQI questionnaire at Days 112, 140 and 168. Safety will be evaluated by physical examination and adverse events evaluation.
