E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
Primary Placebo-family Objectives
Compared with placebo:
• To evaluate the efficacy of brodalumab (210 mg every 2 weeks [Q2W]; and 140 mg Q2W) in
subjects with moderate to severe plaque psoriasis, as measured by the proportion of subjects
achieving 75% improvement in Psoriasis Area and Severity Index (PASI; PASI 75) at
week 12
• To evaluate the efficacy of brodalumab (210 mg Q2W; and 140 mg Q2W) in subjects with
moderate to severe plaque psoriasis, as measured by the proportion of subjects achieving
success (clear [0] or almost clear [1]) on the static physician’s global assessment (sPGA) at
week 12
Primary Ustekinumab-family Objectives
Compared with ustekinumab:
• To evaluate the efficacy of brodalumab (210 mg Q2W; and 140 mg Q2W for subjects
≤ 100 kg with 210 mg dosage for subjects > 100 kg) in clearing psoriasis in subjects with
moderate to severe plaque psoriasis, as measured by the proportion of subjects achieving
PASI 100 at week 12 |
|
E.2.2 | Secondary objectives of the trial |
Placebo-family Objectives:
- To evaluate the efficacy of brodalumab (210 mg Q2W; and 140 mg Q2W) compared with placebo: PASI 100 at week 12; sPGA of 0 at week 12; patient-reported symptoms of psoriasis at week 12.
Ustekinumab-family Objectives:
Compared with Ustekinumab
- To evaluate the efficacy of brodalumab (140 mg Q2W): PASI 100 at week 12
- To evaluate the efficacy of brodalumab (210 mg Q2W; and 140 mg Q2W for subjects ≤ 100 kg with 210 mg dosage for subjects > 100 kg): PASI 75 at week 12 |
|
E.2.3 | Trial contains a sub-study | Yes |
E.2.3.1 | Full title, date and version of each sub-study and their related objectives |
Brodalumab Pharmacokinetic Substudy Objective: To characterize the pharmacokinetics of brodalumab after short- and long-term treatment
Biomarker development and pharmacogentic substudy:
Objective: to collect samples for biomarker analysis; to investigate the effects of genetic variation in disease genes and drug target genes on psoriasis and/or subject response to brodalumab |
|
E.3 | Principal inclusion criteria |
- Subject has provided informed consent.
- Subject is ≥ 18 and ≤ 75 years of age at time of screening.
- Subject has had stable moderate to severe plaque psoriasis for at least 6 months before first dose of IP (eg, no morphology changes or significant flares of disease activity in the opinion of the investigator).
- Subject must be considered, in the opinion of the investigator, to be a suitable candidate for treatment with a biologic per regional labeling.
- Subject has involved body surface area (BSA) ≥ 10%, PASI ≥ 12, and sPGA ≥ 3 at screening and at baseline.
|
|
E.4 | Principal exclusion criteria |
- Subject has any systemic disease (eg, renal failure, heart failure, hypertension, liver disease, diabetes, anemia) considered by the investigator to be clinically significant and uncontrolled.
- Subject has any concurrent medical condition that, in the opinion of the
investigator, could cause this study to be detrimental to the subject.
- Subject has used ustekinumab and/or anti-IL-17 biologic therapy ever or other experimental or commercially available biologic immune modulator(s) within 12 weeks prior to the first IP dose.
- Subject currently is enrolled in another investigational device or drug study, or less than 30 days since ending another investigational device or drug study(s), or receiving other investigational agent(s).
- Other investigational procedures are excluded.
- Subject has known sensitivity to any of the products or components to be
administered during dosing.
- For women: pregnant or breast feeding, or planning to become pregnant while enrolled in the study and for 15 weeks after the last dose (if discontinuing before week 52) or for 8 weeks after the last dose (if discontinuing at or after week 52).
