Trial of Topical Cidofovir for the Prevention of Hair Growth

2014-07-23 16:13:47 | BioPortfolio


This is a single arm, single center placebo-controlled double-blind proof of concept study which will evaluate the safety and efficacy of topical cidofovir (both 1% and 3%)compared to placebo for the prevention of hair growth.


This is a phase II randomized, placebo controlled double blind, dose-ranging clinical trial of topical cidofovir for the prevention of hair growth. This proof of concept study will evaluate 1% and 3% cidofovir in petrolatum topically applied once a day to the target treatment area on the hair bearing area of the face known as the beard area. This target area will be of a circular shape with a diameter of three centimeters along the jaw line of one side of the face. Patients will be randomized in a 1:1 ratio to receive either 1% and placebo or 3% and placebo in a split face design (i.e, the same site on the contra-lateral side of the face will be treated with vehicle only placebo).

Subjects will be given active treatment (either 1% or 3% cidofovir) in combination with placebo for up to six weeks. Any subject who achieves 100% alopecia (which corresponds to a 0 on the PGA of Hair Density) in the treated area prior to six weeks will be classified as a responder and will discontinue active treatment and begin the four week observation period. From the time of discontinuing treatment, subjects will be followed for four weeks during which time safety data will be collected.

Medical and Biotech [MESH] Definitions

Excessive hair growth at inappropriate locations, such as on the extremities, the head, and the back. It is caused by genetic or acquired factors, and is an androgen-independent process. This concept does not include HIRSUTISM which is an androgen-dependent excess hair growth in WOMEN and CHILDREN.

A fibroblast growth factor that may play a role in regulation of HAIR FOLLICLE phenotype. Spontaneous mutation of the gene for this protein results in a strain of MICE with abnormally long hair, referred to as angora mice.

Diseases affecting the orderly growth and persistence of hair.

Specific practices for the prevention of disease or mental disorders in susceptible individuals or populations. These include HEALTH PROMOTION, including mental health; protective procedures, such as COMMUNICABLE DISEASE CONTROL; and monitoring and regulation of ENVIRONMENTAL POLLUTANTS. Primary prevention is to be distinguished from SECONDARY PREVENTION and TERTIARY PREVENTION.

A condition observed in WOMEN and CHILDREN when there is excess coarse body hair of an adult male distribution pattern, such as facial and chest areas. It is the result of elevated ANDROGENS from the OVARIES, the ADRENAL GLANDS, or exogenous sources. The concept does not include HYPERTRICHOSIS, which is an androgen-independent excessive hair growth.
