E.4 | Principal exclusion criteria |
Pregnancy or breast feeding, women of child-bearing potential unless they use highly effective contraception during the study and for 4 weeks after study completion or discontinuation, history or presence of epilepsy, significant neurological disorders, cerebrovascular attacks or ischemia, myocardial infarction or cardiac arrhythmia which requires drug therapy, evidence of severe renal dysfunction or significant hepatic disease, history of lymphoproliferative disorders, patients who are considered potentially unreliable or where it is envisaged the patient may not consistently attend scheduled study visits, inability or unwillingness to undergo repeated venipuncture or skin punch biopsies, any systemic immune-activetreatment within 4 weeks or 5 biologic half-lifes (whichever is longer) or immune-active topical treatment within one week before inclusion, history of failed treatment with an IL-17 inhibitor, history of clinical significant medical condition or any other reason, which the investigator determines would interfere with the subject´s participation in this study or would make the subject unsuitable candidate to receive study drug or would put the subject at risk by participating in the study. |

E.5 End points |
E.5.1 | Primary end point(s) |
Differentially expressed genes in lesional epidermis at baseline and week 12. |
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
|
E.5.2 | Secondary end point(s) |
Proportion of patients reaching at least 90% relative improvement from baseline in the Psoriasis Area and Severity Index (PASI) at 12 weeks of Brodalumab treatment. PASI 75 score at weeks 4 and 12 The proportion of subjects who achieve at least a 75% reduction in the EASI score at weeks 4 and 12 compared to week 0 (Baseline). PASI scores range from 0 to 72, with higher scores reflecting greater disease severity. Erythema, induration, and desquamation are scored on a scale of 0 (none) to 4 (severe) on 4 anatomic regions of the body: head, trunk, upper limbs, and lower limbs. Degree of involvement on each of the 4 anatomic regions is scored on a scale of 0 to 6. The total qualitative score is multiplied by the degree of involvement for each anatomic region and then multiplied by a constant and summed to yield the PASI score.
PASI 50 score at weeks 2, 4 and 12 The proportion of subjects who achieve at least a 50% reduction in the PASI score at weeks 2, 4, and 12 compared to week 0 (Baseline).
PASI 100 score at week 12 The proportion of subjects who achieve a 100% reduction in the PASI score at week 12 compared to week 0 (Baseline).
Absolute Change from baseline in PASI score at weeks 2, 4, and 12
Change from baseline in Investigator Global Assessment (IGA) at weeks 4 and 12 Definition of the IGA 5 point scale 24: 0 Cleared: No plaque elevation, erythema or scaling; hyperpigmentation may be present 1 Minimal: Minimal plaque elevation (=0,25 mm); faint erythema; minimal scaling, with occasional fine scale over 55% of lesion 2 Mild: Mild plaque elevation (=0,5 mm); light red coloration; fine scale predominates 3 Moderate: Moderate plaque elevation (=0,75 mm); moderate red coloration; coarse scale predominates 4 Marked: Moderate plaque elevation (=1 mm); bright red coloration; thick, nontenacious scale predominates 5 Severe: Severe plaque elevation (>1,25 mm); dusky to deep red coloration; very thick, tenacious scale predominates
Change from baseline in the Dermatology Life Quality Index (DLQI) Total Score at weeks 4 and 12 DLQI is a simple, compact, and practical questionnaire for use in a dermatology clinical setting to assess limitations related to the impact of skin disease. The instrument contains ten items dealing with the participant's skin. With the exception of Item Number 7, the participant responds on a four-point scale, ranging from "Very Much" (score 3) to "Not at All" or "Not relevant" (score 0). Item Number 7 is a multi-part item, the first part of which ascertains whether the participant's skin prevented them from working or studying (Yes or No, scores 3 or 0 respectively), and if "No," then the participant is asked how much the skin has been a problem at work or study over the past week, with response alternatives being "A lot," "A little," or "Not at all" (scores 2, 1, or 0 respectively). The DLQI total score is derived by summing all item scores, which has a possible range of 0 to 30, with 30 corresponding to the worst quality of life, and 0 corresponding to the best.
Change from baseline in Peak Pruritus Numerical Rating Scale (NRS) Score at weeks 4 and 12 NRS are used to measure the amount of itching and discomfort a participant experiences. All NRS values range from 0 to 10 (0 = no pruritus, 10 = worst pruritus imaginable) and are reported on each visit. Maximum itch intensity in the last 24 hours before the visit is asked for. Change from baseline is calculated for the NRS scale, where change = visit value − baseline value.
Change from baseline in the Montgomery – Åsberg depression rating scale (MADRS) at weeks 4 and 12 The MADRS was developed and validated to measure the severity of depressive episodes. It contains 10 items that each yield from 0-6, thus 60 is the highest possible score. 7-19 points argue for mild depression, 20-34 for moderate, and >34 for severe depression.
