Filter by:Vitiligo affects approximately 1 to 2% of the global population and significantly impacts people's quality of life. Achieving the best treatment outcomes for vitiligo involves addressing the autoimmune inflammatory response to stop the depigmentation process and promoting the differentiation of melanocyte stem cells to induce repigmentation. The loss of melanocytes in vitiligo is a result of an autoimmune process. While the IFN gamma pathway plays a crucial role in the adaptive immune response in vitiligo, there is increasing evidence highlighting the importance of the innate immune response. Deucravacitinib, an allosteric TYK2 inhibitor, has shown effectiveness and safety in treating psoriasis. It inhibits the responses of IFN alpha (IFNα), IFN beta (IFNβ), and IL12, and may also have an impact on the Th1 response. The hypothesis is that by targeting the IFN type I response and IL12, deucravacitinib could effectively halt the depigmentation process and facilitate repigmentation of vitiligo lesions. When combined with NB-UVB, the process of repigmentation should be significantly enhanced. The primary objective is to compare the proportion of patients treated with deucravacitinib versus placebo achieving VITIL-IA 50 at week 24. Interventions Following central randomization, patients will be assigned to receive either deucravacitinib 12mg daily (QD) or a placebo daily (QD) for a duration of 24 weeks. At the end of this period, patients will be re-randomized to receive either deucravacitinib 12mg QD alone or deucravacitinib 12mg QD + twice weekly narrowband UVB treatment twice weekly for an additional 24 weeks. Throughout the study, there will be a total of six visits conducted: selection, inclusion, Week 12, Week 24, Week 36, and Week 48. In patients who volunteer, a skin biopsy will be performed on both the lesional and peri-lesional areas at baseline, Week 12 and Week 36. Serum and plasma samples will be collected at the screening visit, Week 12, Week 24, Week 36, and Week 48.
The study aims to evaluate the safety and efficacy of the combination of topical baricitinib and 308-nm monochromatic excimer light versus 308-nm monochromatic excimer light alone in treatment of non-segmental vitiligo.
This is a double blinded self controlled randomized trial to assess Autologous Micro Cellular Grafts in surgical treatment of stable resistant vitiligo. Given the stem cells, progenitor cells, and growth factors rich hair follicle based suspension resulting from Autologous Cellular Micro grafts (ACM), we aim at assessing the efficacy of ACM generated suspension in comparison to follicle cell suspension in surgical treatment of stable resistant vitiligo.
A randomized clinical trial that treats vitiligo patients with oral vitamin D and Narrow-Band Ultraviolet B (NB-UVB) phototherapy (intervention group); or placebo and NB-UVB phototherapy (control group). We will evaluate if the group supplemented with vitamin D achieves a higher repigmentation rate than the control group, proving the relevance of vitamin D as an immunomodulator in the pathophysiology of vitiligo. These findings may support the use of vitamin D as an economic, safe, and adjuvant treatment for vitiligo.
Vitiligo is an acquired cutaneous disorder of pigmentation, with a 1-2% incidence worldwide, without predilection for sex or race. People affected by vitiligo have a vast reduction of quality of life, caused by the color contrast between healthy pigmented skin and the depigmented vitiligo patches due to death of melanocytes, which may cause psychological problems to the patient.
Patients will be included in a randomized controlled clinical trial, will enroll only adult vitiligo patients with surface area of at least 10% who are being followed in the outpatient dermatology clinics of King Abdullah University Hospital (KAUH) and are planned to start on phototherapy Narrow Band Ultraviolet light B (NBUVB), regardless if they have previous treatment for their disease, one month wash off period will be given for patients who are already on phototherapy or other treatments for vitiligo.
