Active clinical trials for "Alopecia Areata"

Prospective, observational cohort study for subjects with AA under the care of a dermatology provider. Approximately 5,000 subjects and 100 clinical sites in North America will be recruited to participate with no defined upper limit for either target.

A randomized, double-blind, three-arm, placebo-controlled, safety, and efficacy study of plant-based Biotin and plant-based Biotin with Silica in healthy adult human subjects with complaints of hair fall, thin, dry, and brittle hair, and dry skin. A sufficient number (maximum of 105 (35 subject/test treatment)) of female/male adult subjects will be recruited/enrolled to ensure a total of 96 subjects (32 subjects/test treatment) complete the study.

Alopecia areata (AA) is a type of non-cicatricial alopecia. The most common presentation of AA is localized patches of hair loss on the scalp. The extensive forms of AA presented as diffuse hair loss of the scalp (alopecia totalis) and diffuse hair loss through the entire body including the eyelashes and eyebrows (alopecia universalis). AA affects approximately 2% of the general population. AA occurs at any age. The peak of incidence is higher in the second and third decades of life. AA may be associated with several autoimmune diseases including thyroid diseases, lupus erythematosus, vitiligo, psoriasis, rheumatoid arthritis and inflammatory bowel disease. The frequency of the disease varies between geographically separate populations. These diseases associations suggest a relationship between AA and autoimmunity. Human hair has an important cosmetic and communicational role. We may find significant psychological distress in persons with partial and complete hair loss. AA is associated with psychiatric morbidity especially anxiety and depression. The pathogenesis of AA involves a complex interaction between genetic, environmental and immune factors. The histopathology of the disease differs according to the stage of the disease. In the acute stage of AA, there is a dense accumulation of lymphocytes (CD4 &CD8) around hair bulbs so called swarm of bees. In chronic stage, the inflammation may or may not resolve, but there is increase in number of catagen and, or telogen hair and pigmentary incontinence. In the recovery stage, there is minimal inflammation and increase in anagen hair. T-helper17 cells are unique subset of T-helper cells which produce many interleukins (IL) e.g. IL-17A, IL-17F, IL-21, IL-22, IL-6 and tumor necrosis factor (TNF). The maturation of Th-17 needs the stimulation of naïve T cells by both TGF and IL-21. IL-21 is a cytokine that is produced mostly by activated CD4 T cells. It controls the differentiation and activity of T cells, B cells and NK cells. IL-21 could be a promising marker in the diagnosis of AA and also can be used as a marker of its activity. IL-15 is a pleotropic cytokine that has multiple effects on different body cell types. It affects the function of cells of both innate and adaptive immune system. IL-15 is well known to promote lymphocytic development and suggested to play a role in some autoimmune diseases e.g. multiple sclerosis, rheumatoid arthritis, ulcerative colitis and celiac disease. IL-15 inhibits the well-known self-tolerance that mediated by activation - induced cell death, promotes maintenance of CD8+ memory T cells with induction of some cytokines which involved in autoimmune process e.g. TNF- and IL-1B. IL-15 is positively correlated with the number and the extent of AA so it could be a possible marker of AA severity.

The prevalence of pruritus has been studied in frontal fibrosis alopecia (FFA) and lichen planus pilaris (LPP), but there are no studies evaluating the characteristics of pruritus, the correlation between pruritus and disease activity, and its impact on quality of life. The knowledge of the characteristics of pruritus, of the link "disease activity - pruritus", and its impact on the quality of life could allow us to modify the management of the patient (modification or intensification of therapy, close monitoring...)

To collect, preserve, and/or distribute annotated biospecimens and associated medical data to institutionally approved, investigator-directed biomedical research to discover and develop new treatments, diagnostics, and preventative methods for specific and complex conditions.

We are the missing link in clinical trials, connecting patients and researchers seamlessly and conveniently using a mobile health platform to advance medical research. We make it easy for patients to contribute to research for medical conditions that matter most to them, regardless of their location or ability to travel.

The purpose of this prospective study is to assess the ability of AMMA to prevent hair loss in women receiving chemotherapy (CT) for early-stage breast cancer. Additionally, the purpose is also to assess the safety, tolerability and compliance, quality of life, and satisfaction with hair preservation after CT treatment.

Alopecia areata is a medical condition, in which the hair falls out in patches. The hair can fall out on the scalp or elsewhere on the face and body. Alopecia areata is an autoimmune skin disease, which means that the immune system is recognizing the hair follicles as foreign and attacking them, causing round patches of hair loss. It can progress to total scalp hair loss (alopecia totalis) or complete body hair loss (alopecia universalis). The scalp is the most commonly affected area, but the beard or any hair-bearing site can be affected alone or together with the scalp. Alopecia areata occurs in males and females of all ages, and is a highly unpredictable condition that tends to recur. Alopecia areata can cause significant distress to both patients and their families. Aim: To assess the effects of a new treatment called secukinumab in patients with alopecia areata. A total of 30 patients will be included in the study, which will run for a total of 28 weeks.

This clinical trial attempts to investigate the efficacy of LEO 124249 ointment in the treatment of alopecia areata on the eyebrows.

This is a safety, tolerability, and pharmacokinetics study of bimatoprost in male patients with androgenetic alopecia (AGA).
