Filter by:This is an open-label, single-arm, pilot study on the effects of topical imiquimod treatment in preventing keloid recurrence after surgical excision. Keloids are abnormal scars that form in certain genetically predisposed individuals following trauma to the skin. They can be physically disabling and cause social impairment. Many therapies have been proposed and trialed for the permanent removal of keloids, but they all have limited efficacy. Topical imiquimod therapy has been reported to decrease keloid recurrence following keloidectomy in human patients. Given all previous reports of adjuvant imiquimod therapy to keloidectomy initiated imiquimod therapy after keloidectomy, the investigators would like to test the efficacy of topical imiquimod pre-treatment in preventing keloid recurrence after surgical excision. Therefore, the investigators are initiating an open-label pilot study of 10 patients age 18 or greater with keloids on the trunk and extremities excluding the groin and hands and feet who present to the dermatology clinic for standard of care keloid excision. Key exclusion criteria include vulnerable populations, immunocompromised state, hypersensitivity to study drug components, and keloids outside of specified areas. The main study intervention will be 6 weeks of treatment with topical 5% imiquimod cream, starting 1 week prior to surgical excision.
This is a 3-arm randomised clinical enabling study, with no investigational product. Keloid patients who are scheduled for surgical excision of one or more keloid scars (up to nine) will be recruited to the study. The aim is to investigate how collagen synthesis within keloid scars is affected by the current approved steroid treatment for keloids, triamcinolone acetonide (TAC). The primary endpoint will be fractional collagen synthesis in keloids which have received intra-lesional injections of TAC, placebo or no treatment prior to their removal. Fractional collagen synthesis will be determined using an established isotope/mass spectrometric technique which measures levels of deuterium incorporation into collagen following administration of heavy water to the subject. In addition; keloid tissue samples will be evaluated post surgery to identify further biomarkers of extracellular matrix synthesis and degradation for application in future clinical studies. Subjects will complete a screening visit and will then be randomised to receive three intra-lesional injections of TAC or placebo, or no treatment, at an interval of 2-3 weeks. Subjects will be randomised to different treatment sequences depending on the number of keloids they have scheduled for surgery, in such a way that subjects with multiple keloids will receive different arms of study treatment in their different keloids. Planned surgery for removal of their keloid(s) will be performed at week 6-8. All subjects will receive daily heavy water (Deuterium oxide) administration (twice daily or thrice daily as directed), with the first dose being taken at the Week 2 clinic visit and the final dose being taken on the day prior to surgery. A follow-up visit will be conducted at 1-4 weeks post-surgery.
Keloid scarring is a severe cosmetic and painful disease of the skin. The gold standard treatment is yet to be clarified. This randomized clinical pilot study will compare the effects of two local treatments for preventing keloid recurrence after surgical removal; steroid and verapamil. Study hypothesis: Intralesional therapy with the calcium antagonist verapamil has equal treatment efficacy as steroid injection.
Despite their benign nature, keloids may constitute a severe aesthetic, and in some cases, functional problem which translates to various repercussions on person's quality of life, including much stress and insecurities. Keloids are mostly observed between the ages of 10 and 30. Although keloid is a common condition and the investigators can make assumptions about those living with keloids, the investigators do not know the actual impact of the illness on the overall performance of patients' and how this disease, day to day, is impacting their lives. The investigators are conducting this study, aimed to investigate the psychosocial impact of keloid on daily life. Information is collected anonymously. You must be 18 years of age or older to take this survey. Parents can respond on behalf of their children who are not 18 years of age yet. The online survey will take 20-30 minutes to complete.
Much progress in treatment of various tumors has been made in the laboratory and the results have been brought back to the patients, i.e. from bench to bedside. This trial intends to collect samples of keloid tissue from patients and study them in laboratory. Such a research may help us with finding better treatments for keloid.
Treatment of keloid disorder is an area of unmet medical need. Current treatments for keloid partially address small and localized keloids, yet there are no wholly satisfactory or effective treatments for patients with extensive keloids. Such patients may benefit from effective systemic treatments. Sorafenib has the potential to regulate the three known dysregulated biological pathways in keloid tissue.
Keloid is chronic skin conditions that results in formation of tumor like growths on the skin. Despite its benign nature, keloid can cause severe aesthetic and, in some cases, functional problem which negatively impacts person's quality of life. Keloids do not regress on their own and results of most available treatments such as surgery, injecting keloids with steroids, chemotherapy injections, or even radiation therapy, have mostly proven disappointing. Some laboratory studies have shown that there is excessive amount of a protein called "vascular endothelial growth factor (VEGF)" in keloid tissue. This may play role in the formation and evolution of keloid. Bevacizumab is a drug that works by targeting vascular endothelial growth factor (VEGF) which helps new blood vessels form. Without new blood vessels, the growth of the keloid may be slowed Based on presence of excess amount of VEGF in keloid tissue, we hypothesize that bevacizumab will be effective in treatment of keloids. This exploratory clinical trial is to confirm or reject this hypothesis.
This is a 2-part study. In the first part (Part I, 8 subjects), biopsies will be obtained from the resection site after keloid shaving and two weeks following resection to assess and select biomarkers to determine the biologic effects that occur in shaved keloids. No drug will be administered. In Part II (32 patients) will be randomized to receive QAX576 or placebo. An initial drug infusion will be followed by shave removal of keloids 6 - 8 days later followed by two additional drug infusions 4 weeks apart. Two weeks following resection, punch biopsies will be performed to assess biomarker responses. Patients will be followed-up for 52 weeks after first drug administration to assess keloid recurrence (clinically and by 3D imaging), and by physician's and patient's cosmetic assessments, and safety.
This investigator initiated study, single-blinded, parallel, randomized study will be conducted in subjects with 2 or more keloids similar in size and duration on a similar area of the body. The response of the closure techniques will be evaluated by clinical and instrumental assessments. Each qualified subject will be assessed and the keloids will be randomly assigned to the Clozex or suture closure. One keloid will be surgically excised and the surgical wound generated will be randomized to be closed with Clozex. A second keloid will be surgically excised and the surgical wound generated will be randomized to be closed with sutures. The inflammation index and the keloid recurrence rate at each surgical wound closure site will be compared.
The purpose of this investigation is to evaluate the effectiveness of high-dose UVA1 irradiation in the treatment of fibrosing conditions of the skin, e.g., keloid (a thick scar from growth of fibrous tissue), scleroderma (deposits of fibrous tissue in the skin) and acne keloidalis nuchae (keloids on the back of the neck or hairline) old burn scars, granuloma annulare or other similar skin conditions. This UVA1 dosing schedule has been used successfully in Germany for various skin diseases, such as the above mentioned scleroderma.
