Genetic Test to determine Androgen Sensitivity

• Women with high androgen sensitivity are likely to respond to anti-androgen therapy for the treatment of hair loss (AGA)

• Women with high androgen sensitivity are at an increased risk of developing androgenetic alopecia (AGA)

What is the HairDX Genetic Test?

Science - Androgen Sensitivity

• Androgens are the male sex hormones testosterone and dihydrotestosterone, which are found in smaller amounts in women

• Androgens bind to androgen receptors in cells

• Androgen receptor sensitivity is determined by the genetics of the androgen receptor

• Androgen receptor sensitivity determines the affect of androgens on hair loss and anti-androgen therapy

19 20 21 22 X Y

• Human cells contain 46 chromosomes (23 pairs)

• X and Y are sex chromosomes

• Women have two X chromosomes

• Men have one X and one Y chromosome

Science - Genetics

Science - Genetics

• Chromosomes are made up of DNA

• There are four DNA bases C, A, G and T

• Sets of three DNA bases, called codons, can encode amino acids, e.g., the CAG codon encodes the amino acid glutamine

7Monday, October 11, 2010

Science - Androgen Receptor

• The androgen receptor (AR) gene is located on the X-chromosome

• Androgen sensitivity on the AR gene is determined by the number of CAG repeats

• Women have two differentially activated X-chromosomes; hence, the test determines the CAG repeat in the activated X-chromosome

• Patients with few CAG repeats have an increase in androgen receptor activity and therefore high androgen sensitivity

• Patients with many CAG repeats have a decrease in androgen receptor activity and therefore low androgen sensitivity

HairDX Clinical Study

• Pioneering clinical study conducted by Dr. Sharon Keene (2009-2010)

• Women received 1mg/day finasteride for 6 months

• Hair counts were used to measure finasteride response

• Responders had a CAG score <23.5 had approximately a +24% change in hair counts (gain hair)

• Non-responders had a CAG score ≥23.5 had approximately a -4% change in hair counts (lose hair)

• Replicated in an independent cohort
