A study testing Stratacel and Stratamed in people with Wound Healing, run by Stratpharma AG at 1 site in Switzerland.
Trial summary
Delayed wound healing is considered a health problem with devastating consequences for patients, healthcare systems, and societies. Over the past 20 years, many other groups, as well as ourselves, have evaluated various alternatives to improve wound healing. Read more about this study

About this study
Delayed wound healing is considered a health problem with devastating consequences for patients, healthcare systems, and societies. Over the past 20 years, many other groups, as well as ourselves, have evaluated various alternatives to improve wound healing. Despite this, the scientific evidence demonstrating the efficacy of recently developed treatments is often limited. Stratacel® and Stratamed® are two gels approved by Swissmedic and the FDA for use in improving wound healing. To this end, the efficacy of these formulations has been visually tested by a physician or by patients. Using the most advanced medical technologies (confocal microscopy and LCOCT), this study aims to investigate the effect of these formulations on the healing of human skin. For this research, a total of 20 volunteers will be included in this study. Volunteers will have up to 7 follow-up appointments over 21 days. Each appointment will last approximately 30 minutes and will be used to perform external measurements of skin healing. All volunteers will use the same formulations (Stratacel® and Stratamed®) with the only difference between volunteers being the anatomical area of application of the formulation. This will be determined by chance. The active participation of the participant is requested for the application of the formulations on the skin twice a day during the trial.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
StratacelDevice
Silicone-based formulation registered as a European class IIa, TGA (Therapeutic Goods Administration) and FDA listed Class I medical device (wound dressing).
StratamedDevice
Silicone-based formulation registered as a European class IIa, TGA (Therapeutic Goods Administration) and FDA listed Class I medical device (wound dressing).
| Study group | Role | What they receive |
|---|---|---|
| Control | No intervention | Not described |
| Formulation 1 | Experimental | Not described Receives: Device: Stratacel |
| Formulation 2 | Experimental | Not described Receives: Device: Stratamed |
What is being measured
The primary outcome is the main question the study is designed to answer.
Measurement of erythema severity via erythema index with and without silicon-based formulations.
Erythema severity is measured using the erythema index (EI). EI will be evaluated by a Mexameter by means of duplicate measurements per skin area in arbitrary units.
Measured: 21+-2 days maximum
Secondary outcomes (2)
Time needed for the scab to fall off
Time needed for the scab to fall off will be evaluated through the study of photo documentation conducted thorough the experiment. To obtain the best possible image of the microscopic treatment zones, a DermLite DL4 dermatoscope will be used. The dermatoscope is a non-invasive device, frequently used in dermatology, which allows a better observation of the skin surface by magnifying it.
Measured: 21+-2 days maximum
Volume of microscopic treatment zones (MTZs) and recovery time
Volume of the MTZs and time to recovery will be evaluated using confocal microscopy. Either by using RCM or LC-OCT (both non-invasive), a minimum of 3 MTZs per region will be evaluated. MTZs will also be evaluated following the classical protocol of biopsy fullowed by H\&E staining.
Measured: 21+-2 days maximum

Questions about this trial
What is this clinical trial studying?
A study testing Stratacel and Stratamed in people with Wound Healing, run by Stratpharma AG at 1 site in Switzerland.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 3 inclusion and 8 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 6 Sep 2023. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Switzerland. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Measurement of erythema severity via erythema index with and without silicon-based formulations. (time frame: 21+-2 days maximum). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT05614557, which also lists 7 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 6 Sep 2023.
