Outcomes

Primary Outcomes

Number of Subjects With Adverse Events (AEs)

Number of subjects with adverse events in the safety analysis set, defined by excluding subjects from the full analysis set who either received no treatment with the IMP and/or for whom no post-baseline safety evaluations are available.

Time frame: From Week -1 to Week 8

Number of Subjects With Serum Cortisol Concentration of ≤18 mcg/dl at 30 Minutes After ACTH-challenge at Week 4

Number of subjects with serum cortisol concentration of ≤18 mcg/dl at 30 minutes after ACTH-challenge at Week 4 in the per protocol analysis set, defined as all subjects from the full analysis set who were in the HPA axis cohort but excluding subjects who did not receive any treatment with the IMP, did not provide any results for the HPA axis test at Week 4, or did not meet the inclusion criterion concerning evidence of normal adrenal function at baseline.

Time frame: 30 minutes after ACTH-challenge at Week 4

Change in Albumin-corrected Serum Calcium From Baseline to Week 4

Change in albumin-corrected serum calcium from baseline to Week 4 in safety analysis set. The safety analysis set, defined by excluding subjects from the full analysis set who either received no treatment with the IMP and/or for whom no post-baseline safety evaluations are available.

Time frame: From baseline to Week 4

Change in Calcium Excretion in 24-hour Urine From Baseline to Week 4

Change in calcium excretion in 24-hour urine collection from baseline to Week 4 in the 24-hour urine HPA set, defined as all subjects in the safety analysis set. The safety analysis set is defined, according to the Consolidated Trial Protocol, by excluding subjects from the full analysis set who either received no treatment with the IMP and/or for whom no post-baseline safety evaluations are available.

Time frame: From baseline to Week 4

Change in Calcium:Creatinine Ratio in 24-hour Urine From Baseline to Week 4

Change in calcium:creatinine ratio in 24-hour urine collection from baseline to Week 4 in the 24-hour urine in HPA set, defined as all subjects in the safety analysis set who underwent HPA-axis testing.

Secondary Outcomes

Number of Subjects With Serum Cortisol Concentration ≤18 mcg/dL at Both 30 and 60 Minutes After ACTH-challenge at Week 4

Number of subjects with serum cortisol concentration ≤18 mcg/dL at both 30 and 60 minutes after ACTH-challenge at Week 4 in the per protocol analysis set, defined as all subjects from the full analysis set who were in the HPA axis cohort but excluding subjects who did not receive any treatment with the IMP, did not provide any results for the HPA axis test at Week 4, or did not meet the inclusion criterion concerning evidence of normal adrenal function at baseline.

Time frame: 30 and 60 minutes after ACTH-challenge at Week 4

Change in Calcium:Creatinine Ratio in Spot Urine Samples From Baseline to Week 4

Change in calcium:creatinine ratio in spot urine samples from baseline to Week 4 in the spot urine non-HPA set, defined as all subjects in the safety analysis set who did not undergo HPA-axis testing.

Time frame: From baseline to Week 4

Number of Subjects With 'Treatment Success' According to Physician's Global Assessment (PGA) on Body

Number of subjects with 'treatment success' according to Physician's Global Assessment (PGA) on Body in the full analysis set, defined as the 106 subjects assigned to treatment. Treatment success was defined as 'clear' or 'almost clear' for subjects with at least 'moderate' disease at baseline according to the PGA, and defined as 'clear' for subjects with mild disease at baseline according to the PGA.

Time frame: Week 4

Number of Subjects With 'Treatment Success' According to Physician's Global Assessment (PGA) on Scalp

Number of subjects with 'treatment success' according to Physician's Global Assessment (PGA) on Scalp in the full analysis set, defined as the 106 subjects assigned to treatment. Treatment success was defined as 'clear' or 'almost clear' for subjects with at least 'moderate' disease at baseline according to the PGA, and defined as 'clear' for subjects with mild disease at baseline according to the PGA.

Time frame: Week 4

Percentage Change in PASI From Baseline to Week 4

Percentage change in Psoriasis area and severity index (PASI) score from baseline to Week 4. Psoriasis area and severity index (PASI) assesses extent and severity of clinical signs of psoriasis vulgaris. Body surface is divided in 4 ares: head (incl. neck), arms (incl. hands), trunk (incl. flexures) and legs (incl. buttocks and feet). Each area is scored from 0-6 for extent of psoriasis and from 0-4 for redness, thickness, and scaliness, and an area PASI score is calculated. The total PASI score is calculated from each area's score. The PASI score ranges from 0 (clear skin) to 72 (maximum disease), a PASI score higher than 10 generally corresponds to moderate-to-severe disease.

Time frame: From baseline to Week 4

Number of Subjects With 'Treatment Success' According to the Subject's Global Assessment of Disease Severity on the Body at Week 4

Number of subjects with 'treatment success' according to the Subject's Global Assessment of disease severity on the body at Week 4 in the full analysis set, defined as the 106 subjects assigned to treatment. Treatment success was defined as 'clear' or 'very mild' according to the Subject's Global Assessment of disease severity.

Time frame: Week 4

Number of Subjects With 'Treatment Success' According to the Subject's Global Assessment of Disease Severity on the Scalp at Week 4

Number of subjects with 'treatment success' according to the Subject's Global Assessment of disease severity on the scalp at Week 4 in the full analysis set, defined as the 106 subjects assigned to treatment. Treatment success was defined as 'clear' or 'very mild' according to the Subject's Global Assessment of disease severity.

Time frame: Week 4

Change in Itch as Assessed on a Visual Analog Scale (VAS) From Baseline to Week 4

Change in itch as assessed on a visual analog scale (VAS) from baseline to Week 4 in the full analysis set, defined as the 106 subjects assigned to treatment. The assessments were made on a 100 mm (100 mm = 10 cm) horizontal VAS anchored at 0 ('no itch at all') and 10 ('worst itch you can imagine'). Subjects were asked to put a vertical line on the scale at the spot he/she felt best reflected the maximal itch intensity during the last 24 hours. The distance from 0 to the subject's indication line was measured in mm, thus higher scores indicated a worse outcome.

Time frame: From baseline to Week 4
