Active ongoing inflammatory diseases other than psoriasis that might confound trial evaluations according to Investigator's judgement
Prior exposure to any biologic therapies for any auto‐immune diseases (e.g.: RA, Psoriasis, Crohns Disease, etc)
A significant disease other than psoriasis and/or a significant uncontrolled disease (such as, but not limited to, nervous system, renal, hepatic, endocrine, haematological, autoimmune or gastrointestinal disorders). A significant disease is defined as a disease which, in the opinion of the Investigator, may (i) put the patient at risk because of participation in the trial, or (ii) influence the results of the trial, or (iii) cause concern about the patient's ability to participate in the trial
Major surgery (major according to the Investigator's assessment) performed within 12 weeks before enrolment or planned within 6 months after screening, e.g. total hip replacement
Any documented active or suspected malignancy or history of malignancy within 5 years prior to screening, except appropriately‐treated (in the opinion of the Investigator) basal cell carcinoma of the skin or in situ carcinoma of uterine cervix
Patients who must or wish to continue the intake of restricted medications or any drug considered likely to interfere with the safe conduct of the trial
Currently enrolled in another investigational device or drug trial, or < 30 days (or < 5 half‐lives, whichever is longer) since ending another investigational device or drug trial(s), or receiving other investigational treatment(s)
Chronic alcohol or drug abuse or any condition that, in the Investigator's opinion, makes the patient an unreliable trial participant or unlikely to complete the trial
Women who are pregnant, nursing, or who plan to become pregnant during the course of this trial or within the period at least 6 months following completion or discontinuation from the trial medication
Forms of psoriasis (e.g. pustular, erythrodermic and guttate) other than chronic plaque psoriasis. Drug‐induced psoriasis (i.e. new onset or current exacerbation from e.g. beta blockers or lithium).
Primary or secondary immunodeficiency (history of, or currently active), including known history of HIV infection or a positive HIV test at screening (at the Investigator discretion and where mandated by local authorities)
Known chronic or relevant acute TB; IGRA TB test or PPD skin test will be performed according to the labelling for Humira®. If the result is positive, patients may participate in the trial if further work‐up (according to local practice/guidelines) establishes conclusively that the person has no evidence of active TB. If latent TB is confirmed, then treatment must have been initiated before treatment in the study and continued according to local country guidelines
Known clinically‐significant (in the Investigator's opinion) coronary artery disease, significant cardiac arrhythmias, moderate to severe congestive heart failure (New York Heart Association Classes III or IV) or interstitial lung disease observed on chest X‐ray
A history of any clinically‐significant adverse reaction (including serious allergic reactions, or anaphylactic reaction, or hypersensitivity) to murine or chimeric proteins, previously‐used biological drug or its excipients, or natural rubber and latex
Positive serology for HBV or HCV
Receipt of a live/attenuated vaccine within 12 weeks prior to the screening visit; people who are expecting to receive any live/attenuated virus or bacterial vaccinations during the trial or up to 3 months after the last dose of trial drug
Any treatment (including biologic therapies) that, in the opinion of the Investigator, may place the person at unacceptable risk during the trial
Known active infection of any kind (excluding fungal infections of nail beds), any major episode of infection requiring hospitalisation or treatment with intravenous (i.v.) antiinfectives within 4 weeks of the screening visit or completion of oral anti‐infectives within 2 weeks of the screening visit
Aspartate aminotransferase (AST) or alanine aminotransferase (ALT) > 2.5 times upper limit of normal (ULN) at screening
Haemoglobin < 8.0 g/dL at screening
Platelets < 100,000/μL at screening
Leukocyte count < 4000/μL at screening
Calculated creatinine clearance < 60 mL/min at screening
