- Scalp Investigator Global Assessment (S-IGA) Score Change [ Time Frame: 8 weeks ]S-IGA Success, defined as an IGA score of 'clear' or 'almost clear' plus a 2-point improvement at Week 8. This global assessment scale has five severity grades reported from 0-4 and defined as Clear (0), Almost Clear (1), Mild (2),Moderate (3), Severe (4).

This global assessment scale has five severity grades reported from 0-4 and defined as Clear (0), Almost Clear (1), Mild (2),Moderate (3), Severe (4).
- In subjects with a Baseline SI-NRS (Scalp Itch-Numeric Rating Score) pruritus score of ≥ 4, SI-NRS Success, defined as achievement of a ≥ 4-point improvement from Baseline. [ Time Frame: Week 8 ]SI-NRS is a subject-reported severity of itch at its highest intensity during the previous 24-hour period. The scale is from '0 to 10' ("no itch" to "worst imaginable itch").
- In subjects with a Baseline SI-NRS (Scalp Itch-Numeric Rating Score) pruritus score of ≥ 4, SI-NRS Success, defined as achievement of a ≥ 4-point improvement from Baseline. [ Time Frame: Week 4 ]SI-NRS is a subject-reported severity of itch at its highest intensity during the previous 24-hour period. The scale is from '0 to 10' ("no itch" to "worst imaginable itch").
- In subjects with a Baseline SI-NRS (Scalp Itch-Numeric Rating Score) pruritus score of ≥ 4, SI-NRS Success, defined as achievement of a ≥ 4-point improvement from Baseline. [ Time Frame: Week 2 ]SI-NRS is a subject-reported severity of itch at its highest intensity during the previous 24-hour period. The scale is from '0 to 10' ("no itch" to "worst imaginable itch").
- Change from Baseline (CFB) SI-NRS (Scalp Itch-Numeric Rating Score) [ Time Frame: Week 1 ]SI-NRS is a subject-reported severity of itch at its highest intensity during the previous 24-hour period. The scale is from '0 to 10' ("no itch" to "worst imaginable itch").
- Change from Baseline (CFB) SI-NRS (Scalp Itch-Numeric Rating Score) [ Time Frame: 72 Hours ]SI-NRS is a subject-reported severity of itch at its highest intensity during the previous 24-hour period. The scale is from '0 to 10' ("no itch" to "worst imaginable itch").
- Change from Baseline (CFB) SI-NRS (Scalp Itch-Numeric Rating Score) [ Time Frame: Day 1 ]SI-NRS is a subject-reported severity of itch at its highest intensity during the previous 24-hour period. The scale is from '0 to 10' ("no itch" to "worst imaginable itch").
- In subjects with a Baseline WI-NRS (Worst Itch-Numeric Rating Score) pruritus score of ≥ 4, WI-NRS Success, defined as achievement of a ≥ 4-point improvement from Baseline [ Time Frame: Week 8 ]WI-NRS is a subject-reported severity of itch at its highest intensity during the previous 24-hour period. The scale is from '0 to 10' ("no itch" to "worst imaginable itch".
- PASI-75 (Psoriasis Area and Severity Index-75) [ Time Frame: Week 8 ]A PASI score is a tool used to measure the severity and extent of psoriasis. Psoriasis Area and Severity Index-75; subjects who achieve a 75% reduction in PASI from Baseline.
- Change From Baseline (CFB) in total PSD (Psoriasis Symptoms Diary) score [ Time Frame: Week 8 ]The PSD is a 16-item assessment that measures psoriasis symptoms and impact on functional health. Symptom items assess the severity and bother of psoriasis-related itching, stinging, burning, pain, scaling, and skin color.
- Change From Baseline (CFB) in total PSD (Psoriasis Symptoms Diary) score [ Time Frame: Week 4 ]The PSD is a 16-item assessment that measures psoriasis symptoms and impact on functional health. Symptom items assess the severity and bother of psoriasis-related itching, stinging, burning, pain, scaling, and skin color.
- Change From Baseline (CFB) in total PSD (Psoriasis Symptoms Diary) score [ Time Frame: Week 2 ]The PSD is a 16-item assessment that measures psoriasis symptoms and impact on functional health. Symptom items assess the severity and bother of psoriasis-related itching, stinging, burning, pain, scaling, and skin color.
- PSSI-75 (Psoriasis Scalp Severity Index) [ Time Frame: Week 8 ]The PSSI is used for the measurement of severity of psoriasis. PSSI combines the assessment of the severity of scalp lesions and the area of scalp affected into a single score in the range 0 (no disease) to 72 (maximal disease). PSSI-75 indicates at least a 75% improvement in the PSSI score from Baseline.
- S-IGA (Scalp Investigator Global Assessment) of 'Clear' at Week 8 [ Time Frame: Week 8 ]The S-IGA is a global assessment scale that has five severity grades reported from 0-4 and defined as Clear (0), Almost Clear (1), Mild (2),Moderate (3), Severe (4).
- SI-IGA (Scalp Investigator Global Assessment) [ Time Frame: Week 4 ]S-IGA Success, defined as an IGA score of 'clear' or 'almost clear' plus a 2-point improvement at Week 4. This global assessment scale has five severity grades reported from 0-4 and defined as Clear (0), Almost Clear (1), Mild (2),Moderate (3), Severe (4).
- Change from Baseline (CFB) in PASI (Psoriasis Scalp Severity Index) [ Time Frame: Week 2 ]A PASI score is a tool used to measure the severity and extent of psoriasis.
- S-IGA (Scalp-Investigator Global Assessment) Success [ Time Frame: Week 2 ]S-IGA Success, defined as an IGA score of 'clear' or 'almost clear' plus a 2-point improvement at Week 2. This global assessment scale has five severity grades reported from 0-4 and defined as Clear (0), Almost Clear (1), Mild (2),Moderate (3), Severe (4).
