Outcomes

Primary Outcomes

Percent Change From Baseline in the Severity of Alopecia Tool 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 at Baseline, Week 4, Week 8, Week 12, Week 16, Week 20, and Week 24. 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. 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.

Time frame: Baseline - Week 24

Secondary Outcomes

Percent Change From Baseline in the Alopecia Density and Extent 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 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.

Time frame: Baseline - Week 24

Mean Change From Baseline in Severity of Alopecia Tool 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. 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.

Proportion of Subjects With ≥2 Point Improvement in Scalp Patient Reported Outcome for Target Patch at Week 24

The Scalp Patient Reported Outcome for Target Patch assesses the appearance of the subject's target patch (identified by the subject as his or her most bothersome area of scalp hair loss at Baseline) and was completed by subjects at Baseline, Week 4, Week 12, and Week 24. The assessment has a recall period of "right now" and includes a five-point VRS ranging from "Full hair, scalp of the target patch completely covered with hair" to "no hair, scalp of the target patch completely exposed." The instrument produces a score of 1 to 5, with lower scores indicating more hair covering the subject's target patch. A summary of the proportion of subjects with ≥2 point improvement in Subject Target Patch assessment at Week 24 compared to baseline is presented.

Time frame: Baseline - Week 24

Proportion of Subjects With ≥1 Point Improvement in Scalp Patient Reported Outcome for Entire Scalp at Week 24

The Scalp Patient Reported Outcome for Entire Scalp assesses the appearance of the subject's whole scalp and was completed by subjects at Baseline, Week 4, Week 12, and Week 24. The assessment has a recall period of "right now" and includes a five-point VRS ranging from "Full hair, whole scalp completely covered with hair" to "no hair, whole scalp completely exposed." The instrument produces a score of 1 to 5, with lower scores indicating more hair covering the subject's target patch. A summary of the proportion of subjects with ≥1 point improvement in Subject Entire Scalp assessment at Week 24 compared to baseline is presented.
