Topical CBD Scar Healing Study

Официальное название

The Effects of Topical Cannabidiol on Paramedian Forehead Flap Scar Healing: A Split Scar Study (TOPSCAR)

Обзор

The purpose of this study is to find out what effects (good and bad) that cannabidiol (CBD) has on scar healing and appearance in patients who have undergone paramedian forehead flap reconstruction.

Подробное описание

The patient will be asked to apply a silicone patch to half of the scar and experimental ointment (CBD oil ointment) with silicone patch) to the other half of the scar on their forehead. They will be randomized to which half of the scar the ointment will be applied. Neither they nor their physician will choose which half of the scar will have the experimental ointment applied. Specific instructions will be given to the patient on how to apply each drug (the silicone patch to one segment of the scar and the CBD with silicone patch to the other segment of the scar). They will apply the treatments twice a day for 2 months and, at their follow-up appointments, complete two questionnaires about how the scar is healing. Photographs of the scars will be taken at each visit and will be evaluated to determine if there is an improved outcome in the appearance of the scar.

Вмешательства

• Препарат Vantage Hemp CBD Isolate + Silicone patch
  The study intervention is prospective in nature. This "split scar" study directly compares two parts of the healing scar during clinic visits. Photos will be taken at each visit to track progress. Assessments will be done over a period of around 7 months using the Modified Patient and Observer Scar Assessment Scale, followed by blinded photo evaluations using the Scar Cosmesis and Rating Scale.
• Препарат Silicone patch
  Standard of care silicone patch will be used as the control part of the split scar study. This "split scar" study directly compares two parts of the healing scar during clinic visits. Photos will be taken at each visit to track progress. Assessments will be done over a period of around 7 months using the Modified Patient and Observer Scar Assessment Scale, followed by blinded photo evaluations using the Scar Cosmesis and Rating Scale.

Termination criteria

• There will be immediate termination from the study if any allergic response to the CBD/silicone combination occurs or if the topical application of CBD/silicone significantly worsens the scar outcome at the Follow Up 2 visit or at any subsequent visit.
• Subject will not receive any additional CBD doses if they experience an adverse event assessed as ≥ Grade 3 (including hepatotoxicities and hematologic adverse events, ≥ Grade 2 for the system-organ class of Cardiac Disorders) according to CTCAE v5. They will remain on study in follow-up until the adverse event resolves or stabilizes.
• If the patient voluntarily requests cessation in the study.
• Pregnancy
• Increase in serum transaminases (ALT/AST) to above three times the upper limit of normal or increase in total bilirubin to above two times the upper limit of normal.
• If a subject experiences worsening depression or suicidal ideation or behavior, the participant will be discontinued from treatment with CBD and immediately referred to a mental health professional.
