Inclusion Criteria

Subject must fulfil all of the following conditions or characteristics in order to be considered for study enrolment:
1.Diagnosis of AS, as defined by Modified New York Criteria for Ankylosing Spondylitis (Attachment 1).
2.Active AS, defined on a scale of 0 to 100 by:
·Average duration and intensity of morning stiffness visual analogue scale (VAS) of nlt 30;
·At least 2 of the following:
-Patient global assessment VAS nlt 30 (Attachment 6);
-Average nocturnal and total pain VAS nlt 30 (Attachment 7);
-Bath Ankylosing Spondylitis Functional Index (BASFI; Attachment 3) VAS nlt 30.
3.Presence of peripheral arthritis, defined as nlt 1 tender/painful and swollen peripheral joint or nlt 1 tender/painful hip or shoulder joint.
4.Treatment failure to at least one NSAID of at least three months duration at the maximal recommended or tolerated anti-inflammatory dose, unless NSAIDs are contraindicated.
5.18 years of age or older at time of consent.
6.Negative serum pregnancy test taken at screening in all women except those who were surgically sterile or at least 1 year postmenopausal. Sexually active women of childbearing potential participating in the study must use a medically acceptable form of contraception (which include oral contraception, injectable or implantable methods, intrauterine devices, or properly used barrier contraception). A woman of childbearing potential is defined as one who is biologically capable of becoming pregnant. This includes women who are using contraceptives or whose sexual partners are either sterile or using contraceptives.
7.Agreement by male subjects who are not surgically sterile and female subjects who are not surgically sterile or postmenopausal to use reliable methods of birth control for the duration of the study.
8.Ability to self-inject drug or have a designee who can do so.
9.Capable of understanding and willing to provide signed and dated written voluntary informed consent before any protocol specific procedures are performed.
10.Ability to store injectable test article at 2 C to 8 C.

13.Receipt of intra-articular, intravenous, intramuscular, or subcutaneous corticosteroid within 4 weeks of screening.
14.Abnormality in haematology or chemistry profiles: haemoglobin nmt 85 g/L; haematocrit nmt 27%; platelet count nmt 125 x 10 power 9 /L; white blood cell count nmt 3.5 x 10 power 9 /L; serum creatinine nlt 175 mmol/L; aspartate aminotransferase (AST [SGOT]) and alanine aminotransferase (ALT [SGPT]) nlt 2 times the laboratory’s upper limit of normal.
15.Significant concurrent medical events including:
·Uncontrolled hypertension (defined as screening systolic blood pressure > 160 mm Hg or screening diastolic blood pressure > 100 mm Hg)

·Open cutaneous ulcers
·Known human immunodeficiency virus (HIV), hepatitis B surface antigen (HBsAg), or hepatitis C virus (HCV) positive
·Tuberculosis (TB) infection (Note: follow local country guidelines for appropriate screening and treatment of tuberculosis in the setting of anti-TNF therapy)
·Any condition that, in the investigator’s judgment, might cause this study to be detrimental to the subject
16. Receipt of any live (attenuated) vaccine within 4 weeks prior to baseline
