This study aimed to evaluate the effectiveness of Protescal in preventing post caesarean section hypertrophic scar and keloid formation.
Phase 2a, prospective, randomized, double-blind, intra-subject, placebo-controlled, proof of concept study. Approximately twenty subjects will be randomized 1:1 to one of two treatment arms: Arm A: 2.0 mg/cm OLX10010 biweekly (every two weeks) Arm B: 5.0 mg/cm OLX10010 biweekly (every two weeks) Each treatment arm will have approximately 10 subjects. Each subject will receive both active (OLX10010) and control (placebo) treatment post-hypertrophic scar surgery biweekly (every two weeks) for a total of six doses. Dosing will occur post-surgery on Weeks 2, 4, 6, 8, 10, and 12. Post-treatment follow-up visits will occur at Weeks 18 and 24, and a long-term follow-up visit will occur at Month 12. The Patient and Observer Scar Assessment Scale (both physician and patient scales), Stony Brook Scar Evaluation Scale, Vancouver Scar Scale, and a photograph-based visual analog scale by blinded experts will be completed prior to scar revision surgery, at Weeks 2, 8, 12, 18, and 24, and at Month 12. The overall opinion responses on the physician scales of the POSAS at Week 24 will be used for primary endpoint analysis. The total length of the linear hypertrophic scar line will be divided equally for treatment with OLX10010 and placebo, injected intradermally per centimeter (cm). The OLX10010 end and placebo end of the scar line will be separated by a 2 cm or greater distance depending on the scar length. After the Week 24 visit, all data collected will be cleaned and all data management activities will be completed. After the database is frozen/locked, the primary endpoint efficacy analysis will be completed. If at least one of the treatment arms are shown to be appropriate to reduce recurrence of hypertrophic scars, all analyses will be performed. If the efficacy analysis of Arms A and B indicate the study doses are not as effective as expected, the sponsor may decide to add a third arm (Arm C) to explore the weekly dosing regimen. See detailed summary. Subjects in all study arms will continue in the study until their Month 12 visit. After all subjects complete that visit, data are collected, and data management activities are completed, Month 12 data will be analyzed.
Summary: Keloids and hypertrophic scars are benign fibrous growth, differing mainly by overgrowth beyond the initial defect in keloid whereas hypertrophic scar is confined to initial lesion and tends to regress over the years. Keloids and hypertrophic scars mainly lead to cosmetic disfigurement and functional deformity depending on site of involvement, in addition to symptoms like pain and pruritus, encountered occasionally. These sometimes might lead to psychological impact too. Different treatment options for keloids and hypertrophic scar are silicone gel/ sheets, corticosteroids, cryotherapy, lasers, antineoplastic agents (5-FU, mitomycin-C), surgical excision and immunomodulators (imiquimod) used either as monotherapy or combination therapy. Different studies involving combination of TAC and 5-FU have been done so far which shows better treatment outcome in terms of efficacy and safety. In a recent meta-analysis published in 2017 concluded that combination therapy of 5-FU + TAC offers better outcome than TAC alone, however recommended additional randomized, controlled, large-sample, high quality trial are needed for a more objective analysis of the treatment efficacy and to assess the adverse reaction associated. We are conducting this study the objective to compare the efficacy and safety profile of intralesional triamcinolone acetonide alone and its combination with 5-FU of the treatment of keloids and hypertrophic scars. This study may help in finding out the optimum treatment option in keloid and hypertrophic scar with minimal side effects in our clinical practice.
A prospective, double blind, randomized controlled human clinical trial will be conducted by enrolling patients referred for laser treatment from the USAISR burn clinic. Laser candidates will be asked to participate who have an area of extremity or truncal scar measuring approximately 6cmX6cm total, in one contiguous region. The study sites, will consist of four equally sized treatment areas (3cm x 3cm), will be randomized to be treated with PDL, CO2, a combination of CO2+PDL, and an untreated control for 6 treatments. The areas will be photographed prior to each treatment and at the final visit 4-6 months after the last treatment. Color, pliability and thickness will be measured using a colorimeter, cutometer and high frequency ultrasound respectively at each appointment. Additionally, the Patient Observer Scar Assessment Scale (POSAS) will be used to score the quality of the scar, using two trained, blinded observers. The patients will also be asked on a voluntary basis for a pre-trial and post-trial 3mm punch biopsy to evaluate for the presence of histological changes.
Burns can lead to lesions of total thickness, which extend the reticular layer of the dermis requiring a healing process, resulting in aesthetic problems, hypertrophic and functional scars that causes the patient a state of low esteem and social isolation. Elastic bandage - Kinesio tape - is a low cost therapeutic resource when compared to the compression mesh and silicone gel plates, commonly indicated for the conservative treatment of these scars. The compressive effect of the bandage on the hypertrophic scar tissue promotes the reduction of local vascularization and the realignment of the collagen fibers, resulting in the repair of the multidirectional mobility of the treated tissue. The aim of the study is to determine the effect of elastic bandage with tension on the inflammatory response of hypertrophic scars in patients with deep burns. It is a randomized, triple blind study. Patients aged 18-59 years with hypertrophic scars due to burns will be included, and those with scaling and open wounds in scar tissue will be included, pregnant women and patients who have previously used any therapeutic resource that may have altered the remodeling process of the hypertrophic scar. The bandage will be applied on the scar selected by lottery. The intervention group will receive the bandage with a tension around 70% and the group will control the same bandage without tension. This feature will be used for a period of three to four days. Initial and subsequent evaluations will be performed after 45 and 90 days. Primary outcome: analysis of the inflammatory response. Through immunohistochemistry and the histological evaluation of the organization pattern of collagen fibers. Secondary: aesthetic and functional evaluation of the hypertrophic scar through the Vancouver scale. The statistical analysis will be done by the researcher and his collaborators, in addition to the statistical one, using the statistical programs Epi-Info 3.5 and Medcalc. For categorical variables, where appropriate, use of the chi-square test of association and Fisher's exact test. Regarding the quantitative variables, the unpaired samples were Student's t-test and if the distribution is not normal, the Mann-Whitney test will be used.
Currently, there are limited prevention or treatments available for dyschromia in burn hypertrophic scars (HTSs). The limited available techniques involve transferring melanocytes from unaffected areas to the scar to adjust pigment. These techniques involve the creation of a donor site and do not utilize the cells that may already be present in scars. This study aims to confirm melanocyte presence in regions of hypo- and hyper- pigmented HTS. If melanocytes can be found in regions of hypopigmentation, these scars may be able to be treated in the future by pigmentation stimulators without the need for surgery. Additionally, if pigmentation specific molecules of interest can be found to be up-regulated in hyperpigmented scar, these may be able to be altered by a pharmacotherapy.
A prospective, randomized, controlled study. The patients were divided into two groups with twenty patients per group. The control group received the standard treatment for postburn scars. The treatment group received the standard treatment and treatment of postburn scars with Extracorporeal Shock Wave Therapy 512 impulses of 0.15mJ/mm 2 in each session, twice per week for 4 weeks. The investigators assessed the appearance of scar with the Vancouver Scar Scale (VSS), pruritus and pain with Visual Analog Scale (VAS) before the start of the treatment and at 2 weeks and 5 months after the treatment.
A Phase II prospective, randomized, double-blind, placebo controlled and comparative clinical study evaluating hydrogel scar-management modalities for effective management of hyperproliferative scars and keloids. This is a double-blinded study, which means that neither the evaluating physician nor the subject will know which treatment is administered. Group selection and assignment will be made at random, with a 2 in 5 chance of receiving a market-approved therapy, and 1 in 5 chance of receiving the placebo. Subjects assigned the placebo-moisturizer will receive a standard hypoallergenic dermatological hydrating cream base. Subjects assigned the silicone gel, will receive a commercially available, active comparator.
