What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Percent Change From Baseline in the Severity of Alopecia Tool (SALT) Score at Week 24 | The Severity of Alopecia Tool (SALT) score is a physician administered scale measuring the amount of scalp without any terminal hair assessed by the investigator. Possible scores range from 0 (no scalp hair loss) to 100 (complete scalp hair loss). A negative change in the SALT score over time represents hair regrowth by adding the percentage hair loss in the various areas (i.e. top, back, each side) of the scalp. The primary efficacy variable was the percent change from baseline in SALT score at Week 24. This was calculated as the mean of the changes from Baseline (Visit 2) SALT score to Week 24 (Visit 10) SALT score, divided by Baseline SALT score and expressed as a percentage. | Baseline-Week 24 | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Percent Change From Baseline in the Alopecia Density and Extent Score (ALODEX) at Week 24 | The Alopecia Density and Extent (ALODEX) score is a measurement of the amount of scalp with terminal hair loss assessed by the investigator at Baseline, Week 4, Week 8, Week 12, Week 16, Week 20, and Week 24. ALODEX breaks the scalp up into a grid of 1% scalp surface areas and assigns density rating in each area on a 10 point scale of hair loss (0= no hair loss to 10 = complete baldness). Summation of scores from each 1% scalp surface area provides an overall score which may range from 0 (no scalp hair loss) to 100 (complete baldness). A negative change in the ALODEX score over time represents hair regrowth. | Baseline-Week 24 |

Summation of scores from each 1% scalp surface area provides an overall score which may range from 0 (no scalp hair loss) to 100 (complete baldness). A negative change in the ALODEX score over time represents hair regrowth. | Baseline-Week 24 | 
| Count of Subjects Achieving at Least a 50% Reduction in Alopecia Density and Extent (ALODEX) Score at Week 24 | The Alopecia Density and Extent (ALODEX) score is a measurement of the amount of scalp with terminal hair loss assessed by the investigator. ALODEX breaks the scalp up into a grid of 1% scalp surface areas and assigns density rating in each area on a 10 point scale of hair loss (0= no hair loss to 10 = complete baldness). Summation of scores from each 1% scalp surface area provides an overall score which may range from 0 (no scalp hair loss) to 100 (complete baldness). A negative change in the ALODEX score over time represents hair regrowth. | Baseline-Week 24 | 
| Count of Subjects in Each Treatment Arm Achieving at Least a 50% Reduction in Severity of Alopecia Tool (SALT) Score at Week 24 Compared to Baseline | The Severity of Alopecia Tool (SALT) score is a physician administered scale measuring the amount of scalp without any terminal hair assessed by the investigator. Possible scores range from 0 (no scalp hair loss) to 100 (complete scalp hair loss). A negative change in the SALT score over time represents hair regrowth by adding the percentage hair loss in the various areas (i.e. top, back, each side) of the scalp. | Baseline-Week 24 |
