Active clinical trials for "Keloid"

The study investigates the efficacy and safety of dupilumab in the treatment of keloids

This will be a single-institution pilot study to evaluate the safety and efficacy of radiation therapy (RT) for the treatment of unresected keloids. The primary endpoint will be toxicity within 10 weeks of follow-up. Secondary endpoints will include cessation of growth or shrinkage of keloids, symptomatic response, and impact on quality of life.

The purpose of this pilot study is to evaluate the safety and efficacy of radiation therapy (RT) in the treatment of unresected keloids.

Keloids affect upto 16% of Africans causing significant cosmetic, functional and psychosocial distress. Available treatment options are associated with high recurrence and highly variable symptom relief. Autologous adipose derived stem-cells(ADSCs) have been described to have a potential therapeutic benefit in treating keloids. Investigators will compare intra-lesion single dose Autologous Adipose Derived Stem Cells harvested from abdominal fat to Triamcinolone Acetanoide among 15 patients with keloids treated at Mulago National Referral Hospital in Kampala Uganda between September 2020 and August 2021. These patients will be followed up for keloid volume change at three months following treatment.

The prospective, split-scar, double-blind, randomized controlled study will enroll the patients who are older than 20 years with progressive keloid lesion which is symmetric. Botulinum toxin A will be injected into half of each keloid revision wound immediately after skin closure. The scars will be assessed at 1-year follow-up with Vancouver Scar Scale (VSS), Patient and Observer Scar Assessment Scale (POSAS), and the Cutometer.

This study is a prospective, randomized, double blind, placebo-controlled clinical trial. The study will include a total of 44 subjects with clinically measurable keloid lesions. At least 50% of subjects (at least 22 out of the 44 subjects) will also have documented diagnosis of concomitant type 2 atopic/allergic) inflammatory diseases. In Phase I, subjects will be randomized (3:1) to either receive weekly dupilumab or placebo for 24 weeks. At Week 24, both groups will enter Phase II of the study in which all subjects will receive weekly doses of dupilumab up to Week 52. The treatment period will conclude at Week 52.

Optimal scar healing is of great importance to patients, especially following surgery of the head and neck. This study evaluates the effectiveness of preoperative silicone ointment in wound healing in head and neck surgeries.

Keloids are a common form of hypertrophic scars that by definition last beyond 6 months and grow beyond the site of initial injury. Keloids are a common complaint from patients in dermatology and cause significant functional impairment due to cosmetic disfigurement, itching and pain. Current treatment modalities include intralesional corticosteroids, chemotherapeutic agents and laser therapy. Initial reports have demonstrated that Botulinum toxin type A may be a viable treatment option for keloids that can reduce keloid size and reduce associated symptoms while having fewer side effects when compared to intralesional corticosteroid injection, which can cause unnatural blood vessel growth or skin thinning. To date, no study has carefully examined the efficacy of Botulinum toxin type A in treating keloids or its mechanistic effects on keloid biology. Our aim in this study is to pursue a rigorous, randomized control trial to assess the potential use Botulinum toxin type A to treat keloids. Efficacy will be objectively be mentioned by change in keloid size after treatment, along with subjective measures of patient satisfaction and symptoms, and finally physician rated scores. Also, samples from three patients will be analyzed in the laboratory setting to determine the underlying molecular mechanism behind the effects of Botulinum toxin type A on keloid biology.

Phase 2, randomized, double-blind, multiple arm, controlled study to evaluate safety & efficacy of various doses of STP705 in reducing post Keloidectomy keloid recurrence.

This is a single center, double-blind (patient and investigator), randomized, placebo-controlled study with a split-lesion design, in which selected keloids will receive three consecutive treatments of a) bleomycin and b) placebo (saline (NaCl 0,9%)), administered with an electronic pneumatic jet injector.
