The investigational drug, AIN457 50 mg lyophilizate vials was prepared by Novartis. Reconstitution of AIN457 with 1.2 mL SWFI produced a 47 mg/mL concentrate solution for infusion from which at least 1 mL was useable. The AIN457 concentrate was diluted in 5% glucose bags for infusion through a 0.2 micron in-line filter.

Percentage of ACR Responders Per Treatment at Week 6

responder" defined as 20% or more improvement in at least 4 of 6 criteria: 1) swollen joint count, 2) tender joint count, 3) morning stiffness duration (low back), 4) current low back pain, 5) current peripheral joint pain, 6) patient global assessment A subject is defined as a PsARC responder if, and only if, they have an improvement in two of the following four factors (with at least one factor being a joint count) and no worsening in the remaining factors: 1) Patient global assessment (0-100 VAS scale, improvement defined as decrease of at least 20 units) 2) Physician global assessment (0-100 VAS scale, improvement defined as decrease of at least 20 units) 3) Tender 78-joint count (improvement defined as decrease of at least 30%) 4) Swollen 76-joint count (improvement defined as decrease of at least 30%)

Mastricht Ankylosing Spondylitis Enthesis Score (MASES) Over Time Per Treatment
The MASES included assessments of 13 sites. Enthesitis sites included in the MASES index are: 1st costochondral, 7th costochondral, posterior superior iliac spine, anterior superior iliac spine, iliac crest (all above was assessed bilaterally), 5th lumbar spinous process, proximal Achilles (bilateral). The MASES score is defined as the total number of painful MASES entheses. 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).
Time frame: Baseline and Day 8, 15 and weeks 6, 8, 12, 16 and 24
Psoriatic Area and Severity Index (PASI) Score in Patients Over Time Per Treatment
The PASI assessed the extent of psoriasis on four body surface areas (head, trunk and upper and lower limbs) and the degree of plaque erythema, scaling and thickness. The PASI score accounted for the extent of body surface area affected by the erythema, scaling and thickness, and the severity of these measures. The score ranged from 0 (no disease) to 72 (maximal disease).
Time frame: Baseline, Day 8, 15 and weeks 6, 8, 12, 16, 20 and 24
SpA Research Consortium of Canada (SPARCC) Score Score in Patients Over Time Per Treatment
SPARCC evaluated 18 enthesis sites: medial and lateral epicondyle humerus, supraspinatus insertion, proximal Achilles, greater trochanter, medial and lateral condyl femur, insertion of plantar fascia, quadriceps insertion of patella, inferior pole of patella, and tibial tubercle. SPARCC enthesis index is defined as the total number of painful entheses assessed at the SPARCC sites. Total SI joint scores could range from 0 to 78, with a higher score indicating more signs of disease.
Time frame: Baseline, Day 8, 15 and weeks 6, 8, 12, 16 and 24
Leeds Dactylitis Instrument (LDI) Score in Patients Over Time Per Treatment
The LDI basic measured the ratio of the circumference of the affected digit to the circumference of the digit on the opposite hand or foot, using a minimum difference of 10% to define a dactylitic digit. The ratio of circumference was multiplied by a tenderness score, using a modification of LDI which was a binary score (1 for tender, 0 for non-tender). If both sides were considered involved, the number was compared to data provided in a table. This modification was referred to as LDI basic and was applied in this study. The LDI required a tool to measure digital circumference and this tool was provided to the centers.
Time frame: Baseline, Day 8, 15 and weeks 6, 8, 12, 16 and 24
Disease Activity Score 28 (DA28) in Patients Over Time Per Treatment
The Disease Activity Score (DAS) is a combined index to measure disease activity in arthritic patients. DAS28 is determined using the following variables: 28-joint counts (tender28 and swollen28), CRP, and the participant's general health (GH) Based on the patients global disease activity measured on a Visual Analogue Scale (VAS) of 100 mm (0 - 100). Using the data from these variables, DAS28 is calculated using the following formula: DAS28 = 0.56\*sqrt(TJC28) + 0.28\*sqrt(SJC28) + 0.36\*ln(CRP+1) + 0.014\*GH + 0.96. The calculation results in a DAS28 score from 0 to 10 indicating the current activity of the rheumatoid arthritis of the patient. A DAS28 above 5.1 means high disease activity whereas a DAS28 below 3.2 indicates low disease activity. Remission is achieved by a DAS28 lower than 2.6.
