Popis

Inclusion Criteria:

  • Patients with moderate to severe AS fulfilling the modified New York criteria for a diagnosis of AS and whose disease was not controlled on NSAIDS (on at least one NSAID over a period of at least 3 months at maximum dose). Minimum disease activity for inclusion of patients was assessed based on the ASAS core set domains: back pain & nocturnal pain score ≥ 4 despite concurrent NSAID use, PLUS a BASDAI score ≥ 4. Elevated CRP or ESR was not mandatory for study inclusion
  • No evidence of liver disease or liver injury as indicated by abnormal liver function tests such as serum glutamic oxaloacetic transaminase (SGOT/AST), serum glutamic pyruvic transaminase (SGPT/ALT), gamma glutamyl transpeptidase (GGT), alkaline phosphatase, or serum bilirubin. The investigator was guided by criteria as outlined under exclusion criteria

Exclusion Criteria:

  • For patients who were previously treated with TNF blockers, the following washout periods were required for these patients to be eligible to participate in the trial:
  • month washout period prior to baseline for alefacept
  • month washout period prior to baseline for adalimumab and certolizumab
  • month washout prior to baseline for etanercept or infliximab
  • For patients who were previously treated with immunosuppressive agents other than MTX, SSZ, and systemic corticosteroids, a 1-month washout period prior to baseline was required. Immunosuppressive agents included but were not limited to cyclosporine, mycophenolate, tacrolimus, and 5-aminosalicylic acid (5-ASA). Prednisone had to be kept at a stable dose 4 weeks before baseline and throughout the study and not to exceed 10 mg/day.
  • MTX had to be kept at a stable dose 4 weeks before baseline and throughout the study and not to exceed 25 mg/week.
  • SSZ had to be kept at a stable dose 4 weeks before baseline and throughout the study.
  • In case of previous leflunomide treatment, a wash-out with oral cholestyramine could be considered as an alternative wash-out procedure to increase the elimination of leflunomide. Based on the notion that cholestyramine reduces plasma levels of the active leflunomide metabolite by approximately 40% in 24 hours and by 49% in 48 hours, cholestyramine was to be given orally at a dose of 8 g t.i.d. daily for 10 days. The patient could then be dosed with study drug not earlier than 2 weeks after the start of the cholestyramine wash-out procedure.
  • Patients who were on NSAIDs had to be kept at a stable dose 4 weeks prior to baseline and throughout the study.
  • Positive human immunodeficient virus (HIV: ELISA and Western blot) test result, Hepatitis B surface antigen (HBsAg) or Hepatitis C test result. Any active systemic infection within the past 2 weeks including a positive chest X-ray.
  • Current signs or symptoms of severe, progressive, or uncontrolled renal, hepatic, hematological, gastrointestinal, endocrine, pulmonary, cardiac, neurologic, cerebral, psychiatric, chronic inflammatory diseases with the exception of psoriatic arthritis or other disease which in the clinical judgment of the investigator would make the patient unsuitable for the trial

Časové okno: Baseline, week 6, week 28
The study used MRI with fat-saturating techniques such as short tau inversion recovery (STIR) to look for the presence of bone marrow edema. The Berlin modification of ASspiMRI-a (ASspiMRI-a) scoring technique assesses inflammation in each of the 23 disc vertebral units (DVU), capturing edema and erosion. Scores for each DVU range from 0-3 (0=normal; 1=minor bone marrow edema (less than25% of DVU; 3=severe bone marrow edema (more that 50% of DVU). The composite score ranges from 0 to 69, with higher scores indicating more severe inflammation

BASMI measures the range of motion based on five clinical measurements: 1) cervical rotation, 2) tragus to wall distance, 3) lumbar side flexion, 4) lumbar flexion (modified Schober's) and 5) intermalleolar distance. BASMI 0 = indicates mild disease involvement, 1 = moderate disease, and 2 = severe disease involvement. The results for cervical rotation and lumbar side flexion are the means of the left and right measurements. Scoring range 0-10. The higher the BASMI score, the more severe was the subject's limitation of movement

The BASDAI consists of a 1 through 10 scale (1 being no problem and 10 being the worst problem), which was used to answer 6 questions pertaining to the 5 major symptoms of AS: Fatigue, Spinal pain, Joint pain / swelling, areas of localized tenderness (called enthesitis, or inflammation of insertion sites of tendons and ligaments), morning stiffness duration, and morning stiffness severity. The physician will globally assess the subject's current disease state using a visual analog scale (VAS) scale with 0 being very good and 100 being very bad.

MASES is measured by scoring of entheses of 0 (no tenderness) to 3 (severe tenderness) at 13 sites on the body. The score was derived as the sum of the 13 scores divided by 3 and the total range is 0 (no tenderness) to 13 (severe tenderness).

Časové okno: SF-36:Baseline, week 12, week 28; ASQoL: Baseline, Day 29, week 12, week 28
The Short Form (36) Health Survey (SF-36) measures the impact of disease on overall quality of life and consists of eight subscales (physical function, pain, general and mental health, vitality, social function, physical and emotional health) which can be aggregated to derive a physical-component summary score and a mental-component summary score. Scores range for each subscale from 0 to 10, and the composite score ranges from 0 to 100, with higher scores indicative of better health. ASQoL determined subject's quality of life and is comprised of 18 questions (yes or no) to be completed by the subject. Each statement on the ASQoL is given a score of "1" or "0." All item scores were summed to give a total score or index. Total scores ranged from 0 (good quality of life) to 18 (poor quality of life) related to ability to cope, relationships, mood, sleep, motivation, activities of everyday living, independence, and social life. Decrease in ASQoL score represents improvement.
