Safety and Efficacy of Combining nbUVB to Etanercept in Patients

Innovaderm Research Inc.99 enrolled

Overview

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.

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.

Outcomes

Primary Outcomes

Number of Participants Attaining a 90 Percent Reduction in PASI From Baseline (PASI 90) - ITT

Four anatomic sites - head, upper extremities, trunk and lower extremities - are assessed for erythema, induration, and desquamation. The severity of each sign is assessed using a 5-point scale: * 0 = No symptoms * 1 = Slight * 2 = Moderate * 3 = Marked * 4 = Very marked The area affected by psoriasis within a given anatomic site is estimated as a percentage of the total area of that anatomic site and assigned a numerical value according to the degree of psoriatic involvement from 0-6. Total scale 0 = best and 72 = worst

Time frame: 112 and 140 days

Secondary Outcomes

Number of Participants Attaining a 75 Percent Reduction in PASI From Baseline (PASI 75) - ITT

Time frame: 112, 140 and 168 days

Number of Participants Attaining a 100% Reduction in PASI From Baseline (PASI 100) - ITT

Time frame: 112, 140 and 168 days

Number of Participants Attaining a 50% Reduction From Baseline in PASI From Baseline (PASI-50) - ITT

Number of Patients Attaining a PGA (Physician's Global Assessment) of 0 or 1 - ITT

Number of patients attaining a Physician's Global Assessment (PGA) of clear (0) or minimal (1). PGA scores are evaluated at each time point. The degree of overall lesion severity at the time of the physician's evaluation of the patient evaluated using the following scale: * 0 = clear * 1 = minimal * 2 = mild * 3 = moderate * 4 = severe * 5 = very severe The scale evaluates plaque elevation, scaling and erythema.

Time frame: 0, 84, 112, 140 and 168 days

Dermatology Life Quality Index (DLQI) - ITT

The aim of this questionnaire is to measure how much one's skin problem has affected one's life over the week prior to the visit. Questionnaire is patient-assessed (self-reported). DLQI scores are evaluated at each time point. Scale is from 0 best to 30 worst. 0-1 = no effect at all on patient's life 2-5 = small effect on patient's life 6-10 = moderate effect on patient's life 11-20 = very large effect on patient's life 21-30 = extremely large effect on patient's life

Time frame: 0, 84, 112, 140 and 168 days

Number of Adverse Drug Reactions - ITT

Evaluation of safety of etanercept and nbUVB as compared to etanercept alone by reporting the incidence rates of adverse drug reactions. Definition: A response to a drug that is noxious and unintended and that occurs at doses normally used in man for prophylaxis, diagnosis, or therapy of diseases or for modification of physiological function. Only adverse drug reactions that were at least possibly related to etanercept were recorded. All symptoms observed at the injection site such as erythema, burning, edema and pruritus were recorded together as Injection Site Reaction.

Time frame: 196 days

Number of Infectious Adverse Events - ITT

Evaluation of safety of etanercept and nbUVB as compared to etanercept alone by reporting the incidence rates of infectious adverse events. Definition: An adverse event is any untoward medical occurrence in a patient administered a pharmaceutical product, without regard to the possibility of a causal relationship with this treatment. Only infectious and malignant (including any type of skin cancer) adverse events were recorded.

Time frame: 196 days

Number of Serious Adverse Events - ITT

Evaluation of safety of etanercept and nbUVB as compared to etanercept alone by reporting the incidence rates of serious adverse events. Definition: any adverse event from this study that results in one of the following outcomes, or is significant for any other reason: * death * initial or prolonged inpatient hospitalization * a life-threatening experience (that is, immediate risk of dying) * persistent or significant disability/incapacity * congenital anomaly/birth defect
