Study summary

The goal of this clinical trial is to learn about the efficacy and safety of microneedling-assisted 5-fluorouracil delivery in comparison with intralesional 5-fluorouracil, intralesional corticosteroid, and microneedling with saline for the treatment of pathological scars.

Read the detailed description

Hypertrophic scars and keloids are dermal fibroproliferative disorders unique to humans. They are common and usually occur following burns, trauma, inflammation, or surgery, but sometimes occur spontaneously. Despite an array of therapeutic approaches for scar therapy such as surgical excision, occlusive dressings, topical and intralesional corticosteroids, interferon, cryosurgery, radiation, pressure therapy, laser therapy, retinoic acid, and silicone gel sheeting, no single method provides complete benefit. For this reason, the medical care of HTSs and keloids remains clinically challenging. The study was conducted on 60 patients complaining of HTSs \& keloids.

Terms in these criteria, in plain language(1)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Immunosuppression

A weakened immune system. It can come from an illness, such as HIV or some blood cancers, or from medicines that turn the immune system down, for example after an organ transplant or for an autoimmune disease; steroids at higher doses count.

What researchers measure

Primary outcomes

  1. Vancouver Scar Scale

    To detect the Change in scar severity assessed by the Vancouver Scar Scale based on four scar characteristics (vascularity 0-3, pliability 0-5, height 0-3, pigmentation 0-2) with the minimum total score 0 (normal) and the maximum total score 13 (most severe scar). Higher scores after treatment mean worse outcome.

    Time frame: 3 weeks

  2. ImageJ Analysis

    To objectively assess scar surface area. To quantify treatment effect, the percentage of change in scar area was calculated for each patient using the formula: ■("Percentage of change=" ("Post treatment area - Baseline area" /"Baseline area" )"×100" ), Higher scores mean worse outcomes.

    Time frame: 3 weeks

Secondary outcomes

  1. Patient's satisfaction score

    grade 0 (No satisfaction), grade I (poor less than 25%), grade II (fair 25-50%), grade III (Good 51-75%) and grade IV (Excellent 76-100%). The minimum total score 0 and the maximum total score 100. The higher scores mean a better outcome

    Time frame: 3 weeks

  2. visual analogue scale

    to assess pain and pruritus. The minimum score is 0 indicated no pain or itching and the maximum score 10 represented the most severe pain or itching. The higher score mean a worse outcome

    Time frame: 3 weeks

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Jul 22, 2026, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
