7.2. Have no signs or symptoms suggestive of active TB upon medical history and/or physical examination.
7.3. Have had no close contact with a person with active TB or, if there has been such a contact, will be referred to a physician specializing in TB to undergo additional evaluation, and if warranted, receive appropriate treatment as if having latent TB prior to or simultaneously with the first administration of study agent.
7.4. Within 6 weeks prior to the administration of study agent, either have a negative QuantiFERON-TB Gold test result or have a newly identified positive QuantiFERON-TB Gold test result in which active TB has been ruled out and for which appropriate treatment for latent TB has been initiated either prior to or simultaneously with the first administration of study agent.
7.5. In the event of 2 indeterminate QuantiFERON-TB Gold in-tube tests results, the subjects will be treated as if having latent TB prior or simultaneously with the first administration of study agent.
7.6. Have a chest radiograph (posterior-anterior view), read by a qualified radiologist, whose diagnostic assessment is consistent with no evidence of current active TB or old inactive TB, and taken within 12 months of the study.
7.7. Have a screening laboratory test result as follows: 7.7.1. Hb≥8.5 g/dL or ≥5.3 mmol/L 7.7.2. White blood cell (WBC) count ≥3.5x103 cells/uL 7.7.3. Neutrophils ≥1.5 x103 cells/uL 7.7.4. Platelets ≥100x103 cells/uL 7.7.5. Serum alanine aminotransferase (ALT) and aspartate aminotransferase (AST) levels not exceeding 1.5 times the upper limit of normal (UKN) for the central laboratory conducting the test.
7.7.6. Serum creatinine not exceeding 1.5 mg/dL
- Received previous treatment with any DMARDs.
- Received previous treatment with golimumab or other tumour necrosis factor inhibitor (TNFi) or other biologic drugs.
- Any chronic inflammatory arthritis diagnosed before 16 years old. Exclusions for general safety

Patients with cancer or a history of cancer (other than resected cutaneous basal cell carcinoma, and in situ cervical cancer) within 5 years of screening.
Patients with current crystal or infective arthritis. Patients with chronic infection of the upper respiratory tract (eg. Sinusitis), chest (eg. Bronchiectatic lung disease), urinary tract or skin (eg. Paronychia, chronic ulcers, open wounds) within 4 weeks of screening.
Patients who have a chest radiograph within 3 months prior to the first administration of study agent that shows an abnormality suggestive of a malignancy or current active infection, including TB, histoplasmosis or coccidioidomycosis.
Patients with any ongoing or active infection or any major episode of infection requiring hospitalization or treatment with IV antibiotics within the preceding 30 days of screening and/or orally administered antibiotics in the preceding 15 days of screening.
Patients with abnormal liver function including known liver cirrhosis, fibrosis, or known alcoholic steatohepatitis (NASH) at the time of screening or abnormal blood tests as shown by:
Aminotransferase (AST) / alanine aminotransferase (ALT) > 3x ULN, OR Bilirubin >51umol/L
Patients with known severe hypoproteinaemia at the time of screening, e.g. in nephrotic syndrome or impaired renal function, as shown by:
• Serum Creatinine > 133 mol/L
Patients with known significantly impaired bone marrow function as for example significant anaemia, leukopaenia, neutropaenia or thrombocytopaenia as shown by the following laboratory values at the time of screening:
White blood cells < 3000 x 106/L Platelets < 125 x 109/L Haemoglobin < 9.0 g/dL for males and < 8.5 g/dL for females Patients with a history of latent or active TB prior to screening will not be eligible. For exceptions refer to inclusion criteria.
Subjects must undergo screening for hepatitis B virus (HBV). At a minimum, this includes testing for HBsAg (surface antigen), anti-HBs (surface antibody), and anti-HBc total (core antibody total).
11.1. Subjects who test positive for surface antigen (HBsAg+) are not eligible for this study, regardless of the results of other hepatitis B tests.
11.2. Subjects who test negative for surface antibody (HBsAg-) and test positive for core antibody (anti-HBc+) and surface antibody (anti-HBs+) are eligible for this study.
11.3. Subjects who test positive only for surface antibody (anti-HBs+) are eligible for this study.
11.4. Subjects who test positive only for core antibody (anti-HBc+) must undergo further testing for hepatitis B deoxyribonucleic acid (HBV DNA test). If the HBV DNA test is positive, the subject is not eligible for this study. If the HBV DNA test is negative, the subject is eligible for this study. In the event the DNA test cannot be performed, the subject is not eligible for the study.
Primary or secondary immunodeficiency (history of or currently active) unless related to primary disease under investigation.
