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.

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
Percentage of Participants With a Significant Skin Event (Day 5 Cumulative)
Time Frame: Day 2 to Day 6
Events associated with Day X wear (eg, Day 5) assessed morning of Day X+1 (eg, Day 6). Significant skin event: at least moderate erythema, elevated response or pain upon touch (associated with non-zero erythema). Erythema grading scale: 0 (no visible erythema) to 3.0 (severe erythema, very intense redness) with 0.5 increments. Moderate erythema (2.0): definite redness. Elevated response: edema, papules, vesicle (≤ 0.5 centimeter [cm] diameter), bullae (> 0.5 cm diameter), miliaria rubra, profunda or follicular response. Pain upon touch: skin grader asked "Does your skin hurt when I touch it?"
Day 2 to Day 6

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
Percentage of Participants With Significant Skin Event (Days 1 Through 4 Cumulative)
Time Frame: Day 2 to Day 5
Events associated with Day X wear (eg, Day 4) assessed on the morning of Day X+1 (eg, Day 5).

Erythema grading scale: 0 (no visible erythema) to 3.0 (severe erythema, very intense redness) with 0.5 point increments. Elevated responses included edema, papules, vesicle (≤ 0.5 cm diameter), bullae (> 0.5 cm diameter), miliaria rubra, profunda or follicular response.

Baseline to Day 6
Percentage of Participants Discontinued From Wrap Wear by 8 Hours on Any Day
Time Frame: Baseline to Day 6
Skin assessments performed prior to heatwrap application; participant discontinued wrap wear for day (8 hours) if erythema score ≥ 2 with pain upon touch or elevated response. Outcome included those who discontinued wrap wear by 4 hours on same day. Erythema grading scale: 7 point scale that ranged from 0 (no visible erythema) to 3.0 (severe erythema, very intense redness) with 0.5 point increments. Moderate erythema (2.0) was definite redness. Elevated responses included edema, papules, vesicle (≤ 0.5 cm diameter), bullae (> 0.5 cm diameter), miliaria rubra, profunda or follicular response.
Baseline to Day 6
Percentage of Participants Discontinued From Wrap Wear by 4 Hours on Any Day
