Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Number of Patients in Each Treatment That Have Clinical Success Based on IGA at Day 28 ± 2
Time Frame: 28 Days
The number of patients in each treatment group that have clinical success. Clinical Success is at least a 2-grade improvement from the baseline IGA score. The minimum IGA value is 0, and maximum value is 5. A higher number represents a more severe case of plaque psoriasis. Patients are required to have an IGA score of 2 or 3 at baseline, so all clinical success IGA scores will be either 0 or 1.
28 Days
Number of Patients in Each Treatment That Have Treatment Success Based on TLSS at Day 28 ± 2
Time Frame: 28 Days
The number of patients in each treatment group that have Treatment Success for the Target Lesion based on the TLSS sub-scale scores. Treatment Success is defined as a score of 0 or 1 for each of the three signs and symptoms (erythema, scaling and plaque elevation) for the Target Lesion. Each score has a minimum value of 0 and maximum value of 5, where a higher value represents a more severe sign or symptom. To be considered for inclusion in the study, the Target Lesion must have a plaque elevation score of at least 2.
28 Days

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Number of Patients in Each Treatment That Have Clinical Success Based on IGA at Day 28 ± 2 (Patients With a Baseline IGA Score of 3)
Time Frame: 28 Days
The number of patients in each treatment group that have clinical success. Clinical Success is defined as at least a 2-grade improvement from the baseline IGA score. This measure is limited to patients with a baseline IGA score of 3, so any IGA score of 0 or 1 at Day 28 ± 2 would be a treatment success.
28 Days
Number of Patients in Each Treatment That Have Treatment Success Based on TLSS at Day 28 ± 2 (Patients With a Baseline IGA Score of 3)
Time Frame: 28 Days
The number of patients in each treatment group that have Treatment Success for the Target Lesion based on the TLSS sub-scale scores. Treatment Success is defined as a score of 0 or 1 for each of the three signs and symptoms (erythema, scaling and plaque elevation) for the Target Lesion. Each score has a minimum value of 0 and maximum value of 5, where a higher value represents a more severe sign or symptom. To be considered for inclusion in the study, the Target Lesion must have a plaque elevation score of at least 2. This measure is limited to patients with a baseline IGA score of 3.
28 Days
Number of Patients in Each Treatment That Have Clinical Success Based on IGA at Day 28 ± 2 (Patients With a Baseline IGA Score of 2)
Time Frame: 28 Days
The number of patients in each treatment group that have clinical success. Clinical Success is defined as at least a 2-grade improvement from the baseline IGA score. This measure is limited to patients with a baseline IGA score of 2, so only an IGA score of 0 at Day 28 ± 2 would be a treatment success.
28 Days
Number of Patients in Each Treatment That Have Treatment Success Based on TLSS at Day 28 ± 2 (Patients With a Baseline IGA Score of 2)
Time Frame: 28 Days

Treatment Success is defined as a score of 0 or 1 for each of the three signs and symptoms (erythema, scaling and plaque elevation) for the Target Lesion. Each score has a minimum value of 0 and maximum value of 5, where a higher value represents a more severe sign or symptom. To be considered for inclusion in the study, the Target Lesion must have a plaque elevation score of at least 2. This measure is limited to patients with a baseline IGA score of 2.
