Filter by:The purpose of this study is to determine whether Minoxidil treatment affects hair growth in patients with male pattern baldness or androgenetic alopecia.
The primary purpose of this study is to assess the safety of performing injections of human autologous hair follicle cells. The study will also measure the impact these injections will have on hair growth. 20 patients will be selected for participation in this study (10 males and 10 females) based on their health status, current/past medications, and ability to adhere to protocol-related requirements. All patients will have evidence of mild to moderate androgenetic alopecia (AGA) involving the vertex area of the scalp as defined by the Ludwig (female) or Norwood (male) scales. At the first visit and after completing informed consent, patients provide a blood sample that will be tested for human immunodeficiency virus (HIV), hepatitis, and syphilis one week before having a biopsy from the back of their scalp. The provided scalp biopsy is then processed to isolate hair follicle cells which are then replicated. Patients return to the clinic for injections of their own replicated cells (autologous cells) in medium (verum) and medium alone (control) into two pre-selected treatment areas in their scalp. Assessments of the safety/tolerability of these injections will take place over the next 60 months both at in-clinic visits and telephone follow-up visits. At these visits patients will have their overall health assessed as subjective and objective assessments of the areas that were injected either with verum or control. During the first 24 months of follow-up, digital images will be taken of the scalp and of the two treatment areas injected with either verum or control. Furthermore at 6, 12, and 24 months post-injection, four patients (2 male and 2 female) at each time point will provide biopsies of the injection sites for histopathological analysis. At the 60 month time point, any patients not previously providing biopsies for histopathological analysis will provide biopsies. Total duration of patient participation is approximately 63 months.
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.
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.
The purpose of this study is to evaluate the efficacy of the HairMax LaserComb 2009 12 beam model for androgenetic alopecia in females when treatment is applied as directed.
The purpose of this study is to evaluate the efficacy of the HairMax LaserComb 2009 9 beam model in promoting hair growth in females diagnosed with androgenetic alopecia when treatment is applied as directed.
The purpose of this study is to determine in women the risk/benefit profile and non-inferiority of a topical 5% Minoxidil foam formulation applied once daily for the treatment of androgenetic alopecia in comparison to 2% MTS used twice daily, using objective and subjective efficacy measures and safety assessments for a study period of 24 weeks.
The purpose of this study is to evaluate the efficacy of the HairMax LaserComb 2009 7 Beam model in promoting hair growth in males diagnosed with androgenetic alopecia when treatment is applied as directed.
