Adjudicated Potential Cardiovascular Events
Query!
Assessment method [1]
0
0
Pre-specified cardiovascular events were adjudicated by committees of external experts who were blinded to treatment assignment. Potential events of interest (pEoI) were identified by the investigator, sponsor, review of alerts from central electrocardiogram assessments, and by search of adverse events (AE)/serious adverse event (SAE) listings for events coded to death (coronary and non-coronary), myocardial infarction (non-fatal), all coronary revascularization, unstable angina, stroke (fatal and non-fatal), transient ischemic attack, congestive heart failure, peripheral arterial vascular disease, dyspnoea, and chest pain. The independent reviewers (IRs) determined if the pEoI met the criteria for EoI classification according to the definitions summarized from the Clinical Data Interchange Standards Consortium 'Standardized Definitions for End Point Events in Cardiovascular Trials' published October 2010.

Pre-specified malignancy events were adjudicated by committees of external experts who were blinded to treatment assignment. pEoI were identified by the investigator, sponsor, potential primary event notifications (i.e. malignancies excluding non-melanoma skin cancers) for a specific protocol, events submitted for histopathology review for potential malignancies which met the criteria for potential malignancies, and by search of AE/SAE listings for events coded to Malignant tumors Standard Medical Dictionary for Regulatory Activities (MedDRA) Queries (SMQ) (20000194). IRs determined if the pEoI met the criteria for EoI classification according to the International Classification of Diseases for Oncology, a ten-digit multi-axial classification of the site (4 characters), morphology (4 digits), behavior (1 digit), and grading (1 digit) of neoplasms.

IRs determined if the pEoI met the criteria for EoI classification by assessing DILI (definite, highly likely, probable, possible, unlikely, unrelated or undetermined), pattern (hepatocellular, mixed, cholestatic or undetermined), likely, competing or alternative cause(s), severity (mild, moderate, severe, fatal/transplantation or undetermined), Hy's law case, recovery \& liver failure (all yes, no or undetermined).

CDAI is a composite index consisting of weighted scoring of 8 disease variables: number of liquid or very soft stools, intensity of abdominal pain, general well-being, occurrence of extraintestinal symptoms, need for antidiarrheal drugs, presence of abdominal masses, hematocrit, and body weight. CDAI scores range from 0 to approximately 600 points, higher score indicates higher disease activity. Clinical remission was defined as a CDAI score of less than (\<) 150. Sustained clinical remission was defined as being in clinical remission (CDAI score \<150) at both Week 24 and Week 48. 95 percent (%) Clopper-Pearson exact confidence interval reported for the proportions. n = number of participants with non-missing data.

Inflammatory Bowel Disease Questionnaire (IBDQ) Total Score and Domain Scores (Bowel Function, Emotional Status, Systemic Symptoms, and Social Function) at Baseline and Week 48/ET Visit

Assessment method [12]

The IBDQ is a psychometrically validated patient reported outcome (PRO) instrument for measuring disease-specific quality of life (QoL) in participants with inflammatory bowel disease (IBD). IBDQ consists of 32 items, each item score ranged from 1 (worst possible response) to 7 (best possible response). The 32 items are grouped into 4 domains: bowel function, emotional status, systemic symptoms and social function. The 4 domains are scored as follows: bowel symptoms 10 to 70; systemic symptoms 5 to 35; emotional function 12 to 84; social function 5 to 35. For each domain, a higher score indicates better QoL. Total score is the sum of each item score, and ranged from 32 to 224 with a higher score indicating a better QoL. Positive change in total score indicated improvement in QoL. n = number of participants with non-missing data.

The IBD PRTI modified questionnaire comprises 3 individual questions administered to the participant: participant satisfaction with study treatment; participant preference for study drug over prior treatment (this question on participant preference for study drug is prefaced by a simple question of previous treatment/s for IBD received in order to place the preference question into context) and participant willingness to reuse the study treatment again. Each of these questions (except the question on previous treatment, which is informational only) is scored on a 5 point Likert scale. PSA = Patient Satisfaction Assessment; PPTA = Patient Previous Treatment Assessment; PPA = Patient Preference Assessment; PWA = Patient Willingness Assessment.

EQ5D is a participant rated questionnaire to assess health-related QoL in terms of a single utility score. Health State Profile component assesses level of current health for 5 domains: mobility, selfcare, usual activities, pain and discomfort, and anxiety and depression; 1 indicates better health state (no problems); 3 indicates worst health state ("confined to bed"). Scoring formula developed by EuroQol Group assigns a utility value for each domain in the profile. Score is transformed and results in a total score range from 0.594 to 1.000; a higher score indicates a better health state. n = number of participants with non-missing data.
