About this study
Purpose of the study:
The purpose of the study is to evaluate the therapeutic effect of cryotherpy in treating hypertrophic scar.
It will be hypothesized that:
Cryotherapy may not have an effect on hypertrophic scar.
Read the detailed description
The potential of cryotherapy application in vitro data indicated that using freezing treatment on VFFs + TGF-β1 (myofibroblast) modulated ECM turnover toward antifibrosis and normalization, attenuated myofibroblast differentiation, reduced cell migration, and weakened the contractile activity. On both VFFs ± TGF-β1, freezing treatment raised LP regeneration (HAS1, decorin).
The findings indicate that cryotherapy may play a protective role in scar formation and contribute to lamina regeneration.
Furthermore the need of this study was developed from the lack in the quantitative knowledge and information in the published studies about the effect of cryotherapy on hypertrophic scar.
This study will be designed to provide a guideline about the effect of effect of cryotherapy on hypertrophic scar height, thickness and discoloration, and to assist in planning an ideal treatment regimen for reducing hypertrophic scar.
Delimitations:
This study will be delimited in the following aspects:
- Subjects: Sixty patients suffering from hypertrophic scar will be randomly divided into two equal groups each one has 30 patients.
- Equipment and tools:
2.1. Measurement equipment: Vancouver scar scale. MAPS (Matching Assessment of Scars and Photographs). 2.2. Therapeutic equipment: Gymna Cryoflow ICE-CT. Temperature resistant polymide tape (48 wide).
Hypothesis:
It will be hypothesized that:
Cryotherapy may not have an effect on hypertrophic scar.
Basic Assumptions:
It will be assumed that:
- All patients will receive the same kinds of medication and the same nursing care.
- All subjects are free from any chronic disease.
- All subjects will continue in the study.
- All patients will follow the instructions during the treatment
- Conditions
- Hypertrophic Scars
- Being tested
- cryotherapy (Gymna Cryoflow ICE-CT), Exercising, Positioning and splinting, Pressure Therapy and Massage
- Medical subject headings
- Cicatrix, Hypertrophic
What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
cryotherapy (Gymna Cryoflow ICE-CT)Device
Also called Gymna Cryoflow ICE-CT
Cryotherapy (also called cryoablation) method was produced by James Arnot in England in 1945 to reduce the size of cancerous cells based on the theory that cold blood cells destroy the cells. Campbell White of New York City used cryotherapy as the first dermatological indication in early-stage epithelioma patients in 1890. Later in 1907, Whitehouse described the use of this method in diferent diseases such as pigmented nevus and lupus. In addition, he has published a case series of skin cancers in different face regions.

Questions about this trial
What is this clinical trial studying?
A Phase 2/3 study testing cryotherapy (Gymna Cryoflow ICE-CT) and Exercising, Positioning and splinting, Pressure Therapy and Massage in people with Hypertrophic Scars, run by Zakria Mowafy at 1 site in Egypt.
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 4 inclusion and 5 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: status not confirmed, as of the sponsor's last update on 31 Aug 2020. 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 Egypt. 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.
What does this combined phase mean?
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Results are not available in the source record.
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?
scar height (time frame: 3 months). 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 NCT04532840, which also lists 2 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 31 Aug 2020; AzTrials last refreshed its copy on 6 Nov 2026.
