Safety, Tolerability And On-Body Temperature Of A Disposable Heatwrap Device For The Lower Back

An Open Label Study To Evaluate The Safety, Tolerability And On-Body Temperature Of A Disposable Heatwrap Device For The Lower Back

The objectives of this study are to evaluate the dermal safety and on-body temperature of a disposable heatwrap product when worn while in a supine position for five consecutive days. The product will be worn on the back for approximately 8 hours per 24 hour period.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Percentage of Participants With a Significant Skin Event (Day 5 Cumulative)	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

Outcome Measure	Measure Description	Time Frame
Percentage of Participants With Significant Skin Event (Days 1 Through 4 Cumulative)	Events associated with Day X wear (eg, Day 4) assessed on the morning of Day X+1 (eg, Day 5). 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 point increments. Moderate erythema (2.0): definite redness. Elevated responses: edema, papules, vesicle (≤ 0.5 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 5
Time to First Significant Skin Event	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 point increments. Moderate erythema (2.0): definite redness. Elevated responses: edema, papules, vesicle (≤ 0.5 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?"	Baseline to Day 6
Percentage of Participants With Any Non-zero Erythema Score or Elevated Response (Days 1 Through 5 Cumulative)	Events associated with Day X wear (eg, Day 5) assessed on the morning of Day X+1 (eg, Day 6). Erythema grading scale was a 7 point scale that ranged from 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.	Day 2 to Day 6
Time to First Report of Non-zero Erythema Score or Elevated Response	Erythema grading scale was a 7 point scale that ranged from 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
Time to Worsening of Non-zero Erythema Score or Elevated Response Leading to Study Discontinuation	Participants discontinued study due to adverse event (AE) if erythema ≥ 2.0, pain upon touch associated with non-zero erythema score or elevated response on the morning of Day X+1. 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. Pain upon touch: skin grader asked "Does your skin hurt when I touch it?"	Baseline to Day 6
Percentage of Participants Discontinued From Wrap Wear by 8 Hours on Any Day	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	Skin assessments performed after 4 hours of wear, participants discontinued wrap wear for remainder of day (4 hours) if erythema score ≥ 2 with pain upon touch or elevated response. Erythema grading scale: 7 point scale ranging 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 and follicular response.	Baseline to Day 6
