Trial summary

The goal of this study is to see how an ingredient called kynurenic acid (which we named "FS2") affects scar formation in people with burn injuries that need skin graft surgery. A cream with FS2 will be used on both the area where the skin graft was placed and the area where the skin was taken (donor site). Read more about this study

About this study

Official title: Post-operative Topical Administration of Fibrosis Inhibiting Compound FS2 in a Double- Blind, Randomized, Vehicle-controlled Study Evaluating the Safety and Mitigation of Cutaneous Scarring in Skin Graft and Donor Sites in Burn Patients

The goal of this study is to see how an ingredient called kynurenic acid (which we named "FS2") affects scar formation in people with burn injuries that need skin graft surgery. A cream with FS2 will be used on both the area where the skin graft was placed and the area where the skin was taken (donor site). The cream will be applied after the skin has healed. This study will help us understand if FS2 is safe and effective for mitigating skin scar formation in burn patients.

Read the detailed description

For the first 90 days of the study, neither the patient nor the investigator will know which cream is being used: either the control cream (IP1) or the treatment cream (IP2), which contains 0.5% FS2. The assigned study product will be applied to the donor site and the skin graft site. After the first 90 days, all patients will use the FS2 cream for another 90 days in an open-label period where everyone knows they are receiving FS2.

The graft and donor sites will be photographed and assessed (POSAS and VSS), scored and recorded at the initial visit and again at every assessment visit thereafter.

An interim analysis will take place when about half of the participants (36 people) have finished their Day 90 visit. Based on the results, the study may continue as planned with the two-treatment, blinded design, or it may switch to an open-label format where all patients (those already in the study or newly enrolled) will use the FS2 cream.

Questions about this trial

What is this clinical trial studying?

A Phase 2/3 study testing IP2 - 0.5% w/w FS2 in people with Burn Scar and Burn Wound, run by Birch BioMed Inc at 2 sites in Canada.

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 10 inclusion and 18 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: looking for participants now, as of the sponsor's last update on 30 Sep 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites in Canada. 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?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

Contact Adam Kuttenkeuler (+1519-341-3367 ext. 113, akuttenkeuler@nutrasource.ca), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Scar condition of the skin grafted wound on Day 90 as assessed by VSS (time frame: 90 days). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 30 Sep 2026.
