The primary efficacy endpoint was met with statistical significance in the 8 mg twice-daily and 12 mg twice-daily dose groups relative to placebo.
A statistically significant proportion of patients treated with either 8 mg twice-daily or 12 mg twice-daily of CTP-543 experienced greater scalp regrowth compared to placebo.

47% of patients in the 8 mg twice-daily group and 52% in the 12 mg twice-daily group reported being "satisfied" or "very satisfied," compared to 2% of patients in the placebo group.
