Phase 3
Completed
Conditions
Psoriasis
Interventions
Drug: 2=Clobetasol propionate foam
Drug: 1=Etanercept
Registration Number
NCT01235442
Lead Sponsor
Amgen
Brief Summary

The primary hypothesis of this trial is that the addition of short courses of clobetasol propionate foam to etanercept monotherapy in subjects with moderate to severe plaque psoriasis will yield greater efficacy compared with etanercept monotherapy, as measured by PASI 75 at Week 12.

Primary Outcome Measures
NameTimeMethod
PASI 75 at Week 12Week 12

The percentage of participants with the Psoriasis Area and Severity Indexs (PASI) 75 responses at week 12. PASI is an assessment of psoriasis based on severity of erythema, infiltration, and desquamation as well as area of involvement. The PASI score ranges from 0 to 72. The higher score represents the worse symptom severity. A response was considered a 75% reduction in the PASI score from Baseline.

Secondary Outcome Measures
NameTimeMethod
sPGA (0,1) at Week 12Week 12

The percentage of participants achieving sPGA 0 or 1 at week 12. Static physician global assessment of psoriasis (sPGA) is a physician's global assessment of the participant's psoriasis based on severity of induration, scaling, and erythema. The sPGA of psoriasis comprises a 6-point scale ranging from 0 (clear) to 5 with increasing severity.

sPGA (0,1) at Week 24Week 24

The percentage of participants achieving sPGA 0 or 1 at week 24. Static physician global assessment of psoriasis (sPGA) is a physician's global assessment of the participant's psoriasis based on severity of induration, scaling, and erythema. The sPGA of psoriasis comprises a 6-point scale ranging from 0 (clear) to 5 with increasing severity.

Patient Satisfaction at Week 12Week 12

Patient assessment of treatment satisfaction status at week 12. It is a measure of a participant's level of satisfaction with the medication's control of psoriasis, ranging from "very satisfied" to "very dissatisfied."

PASI 90 at Week 12Week 12

The percentage of participants with the Psoriasis Area and Severity Indexs (PASI) 90 responses at week 12. PASI is an assessment of psoriasis based on severity of erythema, infiltration, and desquamation as well as area of involvement. The PASI score ranges from 0 to 72. The higher score represents the worse symptom severity. A response was considered a 90% reduction in the PASI score from Baseline.

Percent PASI Improvement From Baseline at Week 12Week 12

The percentage of the improvement in PASI score at week 12 from baseline. PASI is an assessment of psoriasis based on severity of erythema, infiltration, and desquamation as well as area of involvement. The PASI score ranges from 0 to 72. The higher score represents the worse symptom severity.

PASI 75 at Week 24Week 24

The percentage of participants with the Psoriasis Area and Severity Indexs (PASI) 75 responses at week 24. PASI is an assessment of psoriasis based on severity of erythema, infiltration, and desquamation as well as area of involvement. The PASI score ranges from 0 to 72. The higher score represents the worse symptom severity. A response was considered a 75% reduction in the PASI score from Baseline.
