Filter by:Alopecia areata (AA) is a disease characterized by areas of hair loss. Localized steroid injections is the standard treatment for limited disease. There are no existing studies that compare different concentrations of steroids in the treatment of AA. This study will compare the efficacy and safety of different concentrations of localized steroid injections in the treatment of AA. Six treatment sessions will be done over 6 to 9 months. The investigators will compare the following concentrations: 2,5mg/ml, 5mg/ml, 10mg/ml, and normal saline.
The purpose of this six month study is to show that dutasteride is safe and more effective than placebo, and at least as safe and effective as finasteride in treating hair loss in men with androgenetic alopecia. Three doses of dutasteride will be investigated.
Androgenic alopecia, the common form of hair loss is a highly heritable disorder of considerable social significance affecting around 40% of adult men and women. A variety of genetic and environmental factors are likely to play a role in androgenetic alopecia. Genetic variants in the human androgen receptor gene (AR) have been reported to be associated with AGA in Caucasians. Other genes involved with hair loss also have been found. One of them being a gene on chromosome 3 (3q26). A recent genome-wide association study in 296 individuals with male-pattern baldness and 347 controls had carried out and five SNPs on chromosome 20p11 were found to be highly significant association for AGA (rs2180439 combined P = 2.7 x 10(-15)). No interaction was detected with the X-chromosomal androgen receptor locus, suggesting that the 20p11 locus has a role in a yet-to-be-identified androgen-independent pathway. The total number of evaluated patients with androgenic alopecia will be at least 300. All patients will be further grouped as good responders or poor responders to conventional medications, such as topical minoxidil and systemic finasteride. Candidate genes potentially involved in gout and its treatment response will be selected from the published literatures; specifically, two resources of candidate genes will be selected: (i) genes which are known to directly link with androgenic alopecia, and (ii) genes are potentially implicated in particular pathways of androgen/estrogen receptors, metabolism and downstream signals, and genes involved in anti-oxidants or hair growth. The SNP genotyping will be performed by MALDI-TOF Mass Spectrometry. Data analysis will be performed by comparing SNPs allele frequency between good responder and poor responder to conventional medications of patients with androgenic alopecia and further comparing to the allele frequency of SNPs in healthy controls. A functional study will also be done to prove the genetic association.
This is a six month clinical trial to evaluate the effectiveness and safety in women with Female Pattern Hair Loss (FPHL), comparing a 5% minoxidil topical foam (MTF) formulation applied once a day versus a topical foam vehicle (placebo) formulation applied once a day.
This study will investigate the safety, tolerability, and pharmacokinetics of new formulation of bimatoprost following topical application in patients with alopecia. Two formulations of bimatoprost will be investigated in Part 1 and a third formulation of bimatoprost will be investigated in Part 2. Part 2 will begin after Part 1 has completed.
Systemic Pulse Glucocorticoids have been shown to be effective in widespread Alopecia areata but not the totalis, universalis or ophiasic type. Whether the failure is due to inadequate dosing, inadequate frequency or other factors is a matter of debate. The investigators decided to conduct this study using the oral pulse steroid, however with higher doses and more frequent pulses to patients with severe forms of Alopecia areata.
This is a year-long clinical trial to evaluate the effectiveness and safety in women with Female Pattern Hair Loss (FPHL), comparing a new 5% minoxidil topical foam (MTF) formulation applied once a day versus the 2% minoxidil topical solution (MTS) applied twice a day. This clinical trial uses an objective measurement called Target Area Hair Count (TAHC) to evaluate if there is a change in the number of hairs in the area being examined after using the product for 24 weeks (and also after using the product for 12 Weeks and for 52 weeks). This trial will determine if the benefit of using either study product outweighs the risks.
The purpose of this study is to ascertain the safety and efficacy of Clobetasol Propionate 0.05% E Foam in the treatment of Central Centrifugal Cicatricial Alopecia.
Previous studies of finasteride treatment in women with hair loss have failed to show positive results, yet, some women have responded anecdotally. Given that polymorphisms of the androgen receptor gene which confer androgen sensitivity impact male response to finasteride therapy, it was hypothesized that the same polymorphism in women may identify the group that will respond. This study is designed to test the impact of finasteride therapy on hair loss in postmenopausal women.
This study will evaluate the safety and efficacy of bimatoprost solution 0.03% once daily application to the upper eyelid margins compared with vehicle in treating eyelash loss or hypotrichosis (inadequate or not enough eyelashes) in children.
