Brief Summary
This study investigates if an adjusted brodalumab dosage regimen will give improved efficacy in psoriasis in patients with a body weight of over 120 kg. The increased dosage regimen will be compared to the standard brodalumab treatment plus placebo.

Conditions
Outcome Measures
Primary Outcomes (1)
Having at least 90% lower Psoriasis Area and Severity Index (PASI) score relative to baseline (PASI 90 response) at Week 40.
The PASI score is the most widely used tool in clinical practice and clinical trials to assess the severity and extent of psoriasis. The assessment is done based on the condition of the disease at the time of evaluation and not in relation to the condition at a previous visit. The investigator will assess the severity of 3 psoriasis disease characteristics (redness, thickness, and scaliness) on each of the 4 body regions, head/neck, trunk, upper extremities, and lower extremities, according to a severity scale. The investigator will also assess the extent of psoriasis within each of the 4 body regions. This gives a composite score ranging from 0-72, with higher values indicating a more severe and/or more extensive condition.
Week 40
Secondary Outcomes (14)
Having static Physician's Global Assessment (sPGA) score of 0 or 1 at Week 40

Study Arms (2)
Brodalumab 210 mg + brodalumab 70 mg add-on* (adjusted brodalumab dosing regimen)
EXPERIMENTALParticipants will receive 210 mg brodalumab subcutaneously at Week 0, Week 1, and Week 2, and then once every 2 weeks. \*Participants not fulfilling a predefined response at any visit with efficacy assessments after Week 16 will receive a dose adjustment to 280 mg brodalumab every 2 weeks.
Brodalumab 210 mg + placebo add-on* (standard brodalumab treatment)
PLACEBO COMPARATORParticipants will receive 210 mg brodalumab subcutaneously at Week 0, Week 1, and Week 2, and then once every 2 weeks. \*Participants not fulfilling a predefined response at any time visit with efficacy assessments Week 16 will receive a dose adjustment to 210 mg brodalumab + placebo every 2 weeks.
Interventions
Brodalumab is an anti-IL-17 receptor antibody, which blocks the inflammatory effects of IL-17 in the skin.
Eligibility Criteria
You may qualify if:
- Signed and dated informed consent has been obtained prior to any protocol-related procedures.
- Age ≥18 to \<75 years at the time of screening.
- Diagnosed with chronic plaque psoriasis at least 6 months before randomisation.
- Body weight ≥120 kg at the time of screening.
- Moderate-to-severe plaque psoriasis as defined by: BSA ≥10% and PASI ≥12 at screening and baseline.
- No evidence of active or latent tuberculosis according to local standard of care.
You may not qualify if:
- Diagnosed with erythrodermic psoriasis, pustular psoriasis, guttate psoriasis, medication-induced psoriasis, or other skin conditions (e.g., eczema) that would interfere with evaluations of the effect of the investigational medicinal product (IMP) on participants with plaque psoriasis.
- Clinically important active infections or infestations, chronic, recurrent or latent infections or infestations, or is immunocompromised (e.g., human immunodeficiency virus, hepatitis B, and hepatitis C).
- Any systemic disease considered by the investigator to be uncontrolled and either immunocompromising the participants and/or placing the participant at undue risk of intercurrent diseases (including, but not limited to, renal failure, heart failure, liver disease, diabetes, and anaemia).
- History of Crohn's disease.
- Myocardial infarction or stroke, or unstable angina pectoris within the past 12 months.
- Any active malignancy.
- History of malignancy within 5 years, except for treated and considered cured cutaneous squamous or basal cell carcinoma, in situ cervical cancer, or in situ breast ductal carcinoma.
- History of suicidal behaviour (i.e., 'actual suicide attempt', 'interrupted attempt', 'aborted attempt', or 'preparatory acts or behaviour') based on the Columbia-Suicide Severity Rating Scale (C-SSRS) questionnaire at screening or at baseline.
- Any suicidal ideation of category 4 or 5 ('active suicidal ideation with some intent to act, without specific plan' or ' active suicidal ideation with specific plan and intent') based on the C-SSRS questionnaire at screening or at baseline.
- A Patient Health Questionnaire (PHQ)-8 score of ≥10 corresponding to moderate-to-severe depression at screening or at baseline.

- Masking Details
- The pre-filled syringes with 210 mg (1.5 mL) brodalumab will be open-label. The packaging and labelling of the pre-filled syringes with 70 mg (0.5 mL) brodalumab or placebo will contain no evidence to distinguish brodalumab from placebo. It is not considered possible to distinguish between brodalumab and placebo visually; both solutions are colourless.
