The ASAS measures symptomatic improvement in Ankylosing Spondylitis (AS) participants in 4 domains: participant global assessment of disease activity, pain, function, inflammation. ASAS 20 = 20 percent improvement from baseline and an absolute change >= 10 units on a 0-10 scale (0=no disease activity; 10=high disease activity) for >= 3 domains, and no worsening in remaining domain.

ASAS 5/6 response is a validated composite assessment, reflecting the proportion of treated patients who achieve within a defined timeframe at least 20 percent improvement in score in at least 5 of a conventional set of 6 clinical domains relevant to AS and no worsening in the remaining domain.

The CDAI will be assessed by collecting information on 8 different Crohn's disease-related variables: extra-intestinal manifestations, abdominal mass, weight, hematocrit, total number of liquid stools, abdominal pain/cramping, use of antidiarrheal drug(s) and/or opiates, and general well-being. The last 4 variables are scored over 7 days by the participant on a diary card. Clinical response defined as reduction of greater than or equal to 70 points and/or 25 percent from baseline in CDAI.

The IBDQ is a 32-item questionnaire used to assess quality of life in participants with inflammatory bowel diseases. Each question has graded responses from 1 (worst situation) to 7 (best situation). Total score ranges from 32 (worst) to 224 (best). Higher scores indicate better quality of life.

Clinical response is defined as a decrease from baseline in the Mayo score by greater than or equal to 30 percent and >= 3 points, and a decrease from baseline in the rectal bleeding sub score to 0 or 1. The Mayo score consists of 4 sub scores (stool frequency, rectal bleeding, endoscopy findings, and physician's global assessment), rated as 0 (normal) to 3 (severe). Total score is calculated as the sum of 4 sub scores and values range from 0 to 12 scores, where 3 to 5 = mild; 6 to 10 = moderate; and 11 to 12 = severe. Higher scores indicate worsening of the disease.

Clinical remission is defined as a Mayo score less than or equal to 2 points, with no individual sub score greater than 1. The Mayo score consists of 4 sub scores (stool frequency, rectal bleeding, endoscopy findings, and physician's global assessment), rated as 0 (normal) to 3 (severe). Total score is calculated as the sum of 4 sub scores and values range from 0 to 12 scores, where 3 to 5 = mild; 6 to 10 = moderate; and 11 to 12 = severe. Higher scores indicate worsening of the disease.
