A sign of ongoing or chronic inflammation process defined as high blood concentration of C reactive protein (> 1.5 times the upper limit of normal). A history of serious infection (associated with hospitalisation and/or which required intravenous antibiotics) within 180 days prior to Randomisation. Previously been treated with adalimumab. Previously been exposed to a monoclonal antibody or fusion protein (other than adalimumab) within 180 days prior to Randomisation and/or there is a confirmed evidence or clinical suspicion of immunogenicity from previous exposure to a monoclonal antibody or fusion protein. Previously been exposed to an immunosuppressive agent or biological agent (any other than a monoclonal antibody or fusion protein) within 120 days prior to Randomisation. Received live vaccine(s) within 30 days prior to Randomisation or who will require live vaccine(s) during the study period. A history of and/or current cardiac disease defined as one of the following: Personal or family history of prolonged QT interval syndrome or Torsade de Pointes. QT interval corrected by Fridericia's formulas > 450 msec or PR interval outside the range 120 to 220 msec. Signs and symptoms or any history suggestive for heart failure. Any other cardiac abnormalities or conditions assessed as clinically significant. Impaired liver, pancreas and biliary system as determined by one of the following: Serum alanine transaminase and/or aspartate transaminase ≥ 1.5 times the upper limit of normal. Gallbladder or bile duct disease classified as clinically significant. Acute or chronic pancreatitis. A positive hepatitis C virus antibody test or hepatitis B virus surface antigen test, or signs for active or chronic hepatitis B. Hepatic disease classified as clinically significant. A positive test result for human immunodeficiency virus, or have a history of immunodeficiency. A history of malignancy (including lymphoma and leukaemia) other than a successfully treated non-metastatic cutaneous squamous cell carcinoma, basal cell carcinoma or localised carcinoma. Had surgery within 90 days prior to Randomisation, and/or who plan to have an operation during the study period. A history and/or current presence of an illness within 14 days prior to Randomisation that is classified as clinically significant. Have a history of and/or current Coronavirus Disease-19 (COVID-19) defined as one of the following: Positive test result for COVID-19 confirmed by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) using real-time reverse transcriptase polymerase chain reaction (RT-PCR) at Day -1. Signs and symptoms consistent with COVID-19 30 days prior to Randomisation. Have had a positive test result for COVID-19 confirmed by SARS-CoV-2 detection using real-time RT-PCR. Had severe course of COVID-19. Smoked more than 10 cigarettes, 2 cigars or 2 pipes per day within 90 days prior to Screening. Regular consumption of alcoholic beverages that exceeds 14 units. A positive urinary drug screening result. Any prescription medicine or over-the-counter medicines (except paracetamol) that might have an effect on the objectives of the study in the opinion of the Investigator, within 30 days prior to Randomisation. Donated > 100 mL blood or plasma within 28 days prior to Randomisation. Participated in another study with an investigational drug within 60 days prior to Randomisation or are currently participating in or intending to participate in another clinical study of an investigational drug before completion of all scheduled evaluations in this clinical study. Subjects who, in the opinion of the Investigator, are not likely to complete the study for whatever reason. Subject who is the Investigator or any sub-Investigator, research assistant, pharmacist, study coordinator, other staff or relative thereof directly involved in the conduct of the clinical study. Vulnerable subjects.
