Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Percent Change From Baseline in Severity of Alopecia Tool I (SALT I) at Week 24: DB Treatment Period
Time Frame: DB Treatment Period: Baseline (before dose on Day 1), Week 24
SALT I is a well-validated metric used to determine the degree of hair loss based on the percentage (%) of scalp surface area involved on the top (40%), back (24%), left side (18%) and right side (18%) of the scalp for AA. Investigator determines the % scalp hair loss in a given quadrant, multiply this by the total scalp area delineated by that quadrant, and sum the resultant numbers for each quadrant to give the total % scalp hair loss with a maximum score of 100. Score range from 0% (no scalp hair loss) to 100% (complete scalp hair loss), higher scores indicated more scalp hair loss. Percent change from baseline in SALT I is reported in terms of Least square mean and standard error.
DB Treatment Period: Baseline (before dose on Day 1), Week 24

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Change From Baseline in SALT I at Week 24: DB Treatment Period
Time Frame: DBT Period: Baseline, Week 24
SALT I is a well-validated metric used to determine the degree of hair loss based on the percentage (%) of scalp surface area involved on the top (40%), back (24%), left side (18%) and right side (18%) of the scalp for AA. Investigator determines the % scalp hair loss in a given quadrant, multiply this by the total scalp area delineated by that quadrant, and sum the resultant numbers for each quadrant to give the total % scalp hair loss with a maximum score of 100. Score range from 0% (no scalp hair loss) to 100% (complete scalp hair loss), higher scores indicated more scalp hair loss. Change from baseline in SALT I is reported in terms of Least square mean and standard error.
DBT Period: Baseline, Week 24
Percentage of Participants Who Achieved Greater Than or Equal to (>=) 30%, >= 50% and >=75% Improvement From Baseline in SALT I at Week 24: DB Treatment Period
Time Frame: DB Treatment Period: Baseline, Week 24
SALT I is a well-validated metric used to determine the degree of hair loss based on the percentage of scalp surface area involved on the top, back, and each side of the scalp for alopecia areata (AA). Investigator determine the percent scalp hair loss in a given quadrant, multiply this by the total scalp area delineated by that quadrant, and sum the resultant numbers for each quadrant to give the total percent scalp hair loss with a maximum score of 100. Score range from 0 to 100, where 0 =no scalp hair loss to 100 = complete scalp hair loss, higher scores indicated more scalp hair loss. Percentage of participants who achieved >=30%, >=50%, >=75% improvement from baseline in SALT I at Week 24 was reported in this outcome measure.
DB Treatment Period: Baseline, Week 24

Other Outcome Measures

Other Outcome Measures

For clinical trials, a planned measurement described in the protocol that is used to determine the effect of an intervention/treatment on participants. For observational studies, a measurement or observation that is used to describe patterns of diseases or traits, or associations with exposures, risk factors, or treatment. Types of outcome measures include primary outcome measure and secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Number of Participants With Adverse Events (AE): DB Treatment Period
Time Frame: DB Treatment Period: From first dosing date in DB up to (before the first dosing date in OLE) or (last dosing date + 4 weeks + 3 days), whichever is earlier (maximum up to 29 weeks)
An AE is any untoward medical occurrence in a participant temporally associated with the use of a medicinal product, whether or not considered related to the medicinal product. Serious adverse event (SAE) is any untoward medical occurrence that at any dose results in death, is life-threatening, requires hospitalization or prolongation of existing hospitalization, results in disability/incapacity, is a congenital anomaly/birth defect, other situations based on medical significance or any diagnosis of progressive multifocal leukoencephalopathy (PML). AEs included serious AEs and all non-SAEs.
DB Treatment Period: From first dosing date in DB up to (before the first dosing date in OLE) or (last dosing date + 4 weeks + 3 days), whichever is earlier (maximum up to 29 weeks)
Number of Participants With Adverse Events: OLE Period
Time Frame: OLE period: From first dosing date in OLE up to last dosing date + 4 weeks + 3 days (maximum up to 33 weeks)
An AE is any untoward medical occurrence in a participant temporally associated with the use of a medicinal product, whether or not considered related to the medicinal product. An SAE is any untoward medical occurrence that at any dose results in death, is life-threatening, requires hospitalization or prolongation of existing hospitalization, results in disability/incapacity, is a congenital anomaly/birth defect, other situations based on medical significance or any diagnosis of PML. AEs included serious AEs and all non-SAEs.
OLE period: From first dosing date in OLE up to last dosing date + 4 weeks + 3 days (maximum up to 33 weeks)
