Study Details

Study Description

Brief Summary

This is an open, evaluator blinded, intra-comparative, randomized, non-inferiority investigation prior to CE mark to confirm safety and performance of the SWIS device when used as intended, i.e. as an irrigation solution for mechanical rinsing of breached or compromised skin as a result from acute wounds.

Condition or Disease	Intervention/Treatment	Phase
Wound of Skin	Device: SWIS	N/A

Study Design

• Study Type: Interventional
• Actual Enrollment: 20 participants
• Allocation: Randomized
• Intervention Model: Parallel Assignment
• Masking: Single (Outcomes Assessor)
• Primary Purpose: Prevention
• Official Title: Safety and Performance of SoftOx Wound Irrigation Solution (SWIS) Compared to Normal Saline (NS) in Human Experimental Suction Blister Wounds
• Actual Study Start Date: Nov 16, 2020
• Actual Primary Completion Date: Mar 30, 2021

Arms and Interventions

Arm	Intervention/Treatment
Experimental: SoftOx Wound Irrigation Solution (SWIS) Blister wounds will be irrigated and soaked for 15 minutes.	Device: SWIS; Bilateral experimental blister wounds on each forearm. The wound on one arm is rinsed with experimental solution (SWIS) and the contralateral wound on the other arm is rinsed With Saline as a comparator.
Active Comparator: Normal Saline Blister wounds will be irrigated and soaked for 15 minutes.	Device: SWIS; Bilateral experimental blister wounds on each forearm. The wound on one arm is rinsed with experimental solution (SWIS) and the contralateral wound on the other arm is rinsed With Saline as a comparator.

Outcome Measures

Primary Outcome Measures

1. Degree (percentage) re-epithelialization in the suction blister wound on day 10 in the SWIS treated wound versus NS treated wound [From baseline to day 10]

   Measure the degree of re-epithelialization to evaluate any differences between the treatments.

Secondary Outcome Measures

1. Degree (percentage) re-epithelialization in the suction blister wound on day 4 in the SWIS treated wound versus NS treated wound. [From baseline to day 4]

   Evaluate any differences between the two treatments on early epithelialization.

2. Percentage of suction blister wounds healed on day 10 in the SWIS treated wound versus NS treated wound [Day 10]

   Evaluate any differences between the two treatments on day 10

3. Percentage of suction blister wounds healed on day 17 (+/- 1 day) in the SWIS treated wound versus NS treated wound [Day 17]

   Evaluate any differences between the two treatments on day 17

4. Percentage of suction blister wounds with >30% CFU reduction in the SWIS treated wound and NS treated wound respectively if positive CFU level prior irrigation [Day 4]

   Evaluate any differences between the two treatments on reducing bacterial load in wounds

5. Subject evaluation of pain during each irrigation procedure on days 0, 2 and 4 in the SWIS treated wound versus NS treated wound [Baseline (day 0), day 2 and day 4]

   Evaluate any differences on pain using VAS scale between the SWIS and Normal Saline during irrigation and moistening on day 0,2 and 4.

6. The incidence and severity of adverse events [Baseline to day 17]

   Evaluate any differences between the two treatments regarding side effects
