TSQM-9 was a 9-item clinically validated psychometric instrument developed from the TSQM 1.4. TSQM-9 measures participant satisfaction with the medication in 3 domains: Effectiveness, convenience, and global satisfaction. The scores were computed by adding items for each domain, i.e., 1 to 3 for effectiveness, 4 to 6 for convenience, and 7 to 9 for global satisfaction. The lowest possible score (1 for each item and 3 for all 3 subscales) was subtracted from the composite score and divided by the greatest possible score range. The greatest range was (7-1) x 3 items = 18 for effectiveness and convenience, and (5-1) x 3 items = 12 for global satisfaction. This provided a transformed score between 0 and 1 that was then multiplied by 100. TSQM-9 domain scores range from 0 to 100, with higher scores indicating greater satisfaction for that domain.

FAS included all those participants in the safety population that had at least one post-baseline assessment for primary endpoint.

Scalpdex is a scalp dermatitis-specific quality of life (QoL) instrument that can be used to determine which aspect of the disease most bothers the participant and to evaluate QoL as one variable of responsiveness to the therapeutic intervention. It has 23 items, with possible answers scoring on a 5-point Likert-type scale of 0 to 100 ("never" = 0, "rarely" = 25, "sometimes" = 50, "often" = 75, and "all the time" = 100). The final domine scores (symptoms, emotions, and functioning) are calculated by the mean of the item scores pertaining to each scale is the average of the scores of the 23 items with range of 0 to 100. A lower score on symptoms, emotions, and functioning represents a better related-QoL for each scale.

Scalp-PGA treatment success was defined as a scalp-PGA score of 0 (clear) or 1 (almost clear) and with a minimum 2 points improvement from baseline, on the scalp.

FAS included all those participants in the safety population that had at least one post-baseline assessment for primary endpoint. Here, "Overall Number of Participants Analyzed" signifies participants who were evaluable for this outcome measure and "number analyzed" signifies who were evaluable at specific timepoints.

WI-NRS is a self-administered scale to assess participants worst level of itching on the scalp (in the last week). The scale has a single-item that describes the worst level of itching on the scalp due to psoriasis in the last week on an 11-point scale anchored at 0 (no itching) and 10 (worst itching imaginable).

FAS included all those participants in the safety population that had at least one post-baseline assessment for primary endpoint.
