Brief summary
The aim of the study is to assess the efficacy and safety of the combination of intralesional triamcinolone (at doses of 4mg / cm2 at intervals of 4 weeks) and topical pirfenidone 8% (every 8 hours continuously) compared with their isolated application, in the treatment of keloid scars in adults. The duration of this three-arm clinical trial will be 12 months, a 6-month period for treatment and a follow-up of 6 months to assess recurrences. The estimated number of persons to be recruited and randomized for the study is 102.
Detailed description
Individuals with keloid scars will be randomized to 3 arms of treatment in order to assess the efficacy of combining intralesional triamcinolone and topical pirfenidone compared with the isolated application of these drugs. The interventions will last 6 months but the individuals will be assessed monthly to determine recurrences for 6 more months. The scar size will be measure at weeks 12, 24 and 52.
Interventions
Pirfenidone 8% gel will be applied three times per day during 6 months in the surface of the keloid scar.
Triamcinolone will be injected in the keloid scar 4 mg/cm2 every 4 weeks for 6 months. And pirfenidone 8% gel will be applied three times per day during 6 months in the surface of the keloid scar.
Triamcinolone will be injected in the keloid scar 4 mg/cm2 every 4 weeks for 6 months.
