Active clinical trials for "Alopecia Areata"

Topical minoxidil is the most common drug used for the treatment of AGA in men. While topical minoxidil exhibits a good safety profile, the efficacy in the overall population remains relatively low i.e., 30-40% re-grow hair. To observe significant improvement in hair growth, minoxidil is typically used twice daily for a period of at least 16 weeks. Due to the significant time commitment and low response rate, a diagnostic test to identify non-responders prior to initiating therapy would be advantageous. Minoxidil is converted in the scalp to its active form, minoxidil sulfate, by the sulfotransferase enzyme SULT1A1. The enzyme expression is variable among individuals. We have demonstrated in two prior feasibility studies that the SULT1A1 enzyme activity in plucked hair follicles correlates with minoxidil response in the treatment of AGA and thus can server as a predictive biomarker. Consequently, we developed a minoxidil response in-vitro diagnostic kit intended to identify non-responders prior to initiating therapy with 5% topical minoxidil foam. The primary purpose of this study is to evaluate the clinical validity of the minoxidil response in-vitro diagnostic kit.

The primary purpose of this study is to evaluate the clinical validity of the minoxidil response in-vitro diagnostic kit.

Hair loss occurs commonly as a result of radiotherapy administered to the brain, and this can contribute to the distress and social isolation of patients with advanced cancer. In this study a topical gel will be applied directly to the scalp during each dose of radiotherapy. The goal is to determine to what extent the experimental drug is successful in lessening the hair loss.

Post-marketing surveillance(PMS) to monitor the safety and effectiveness of dutasteride in Korean androgenetic alopecia patients

It is a well known fact that the JAK-STAT pathway plays a pivotal role in the pathogenesis of alopecia areata. Both phosphorylated STAT 1 and 3 have been found to be upregulated in the disease. However, whether this pathway plays a role in other hair loss disorders remains unclear. The study aims at assessing STAT3 levels in male patients with androgenetic alopecia. The investigators hypothesize that STAT3 levels will be elevated (due to a previous study proving that JAK-STAT pathway is involved in non-immune mediated hair loss in mice.

The objective of this study is to assess the parathyroid-vitamin D-calcium axis in subjects with alopecia areata. The hypothesis behind this study is that hypovitaminosis D might contribute to the pathogenesis of alopecia areata.

The study series consists of three studies with the aim to assess the incidence, prevalence, risk factors, comorbidities and management of patients with alopecia areata in Czech Republic based on the patients and registry of a dermatology clinic of a metropolitan hospital.

Coronavirus disease 2019 (COVID-19) can cause variable symptoms ranging from mild common cold-like symptoms to severe life threatening pneumonia. Recent studies show severe outcomes of COVID-19 patients specially in males who suffer from androgenetic alopecia, would be significant and is of particular interest of this study and could help further support the hypothesis that anti-androgen therapy might represents an additional potential intervention against severe COVID-19.

The purpose of this study is to determine whether Minoxidil treatment affects hair growth in patients with male pattern baldness or androgenetic alopecia.

The purpose of this study is to assess whether patients with the classic form of Fabry disease have significantly less androgenic alopecia (male pattern baldness).
