Trial Outcomes & Findings for Moderate Rheumatoid Arthritis (RA) With Etanercept (Enbrel) (NCT NCT01313208)

NCT ID: NCT01313208

Last Updated: 2017-02-09

Results Overview

Low disease activity is defined by a disease activity score (28 joint) calculated using the C-reactive protein formula (DAS28-CRP) of less than 3.2. The DAS28 is a composite score to measure disease activity in patients with rheumatoid arthritis, derived from the following variables: • The number of swollen and tender joints assessed using the 28-joint count; • C-Reactive Protein (CRP) level • Patient's global assessment of disease activity measured on a likert scale from 0 (no activity at all) to 10 (worst activity). The DAS28 score ranges from zero up to approximately ten. DAS28 scores above 5.1 indicate high disease activity.

PRIMARY outcome

Timeframe: Week 12

Population: Primary analysis set (all randomized participants); last observation carried forward (LOCF) imputation was used.

Low disease activity is defined by a disease activity score (28 joint) calculated using the C-reactive protein formula (DAS28-CRP) of less than 3.2. The DAS28 is a composite score to measure disease activity in patients with rheumatoid arthritis, derived from the following variables: • The number of swollen and tender joints assessed using the 28-joint count; • C-Reactive Protein (CRP) level • Patient's global assessment of disease activity measured on a likert scale from 0 (no activity at all) to 10 (worst activity). The DAS28 score ranges from zero up to approximately ten. DAS28 scores above 5.1 indicate high disease activity.

The Multi-Dimensional Health Assessment Questionnaire (MDHAQ) is adapted from the standard HAQ and is used for the computation of the Routine Assessment of Patient Index Data 3 (RAPID3). The RAPID 3 includes the 3 Core Data Set measures of physical function, pain, and patient global estimate. The score for physical function ranges from 0 to 10 and is calculated by adding the ten activities of daily living, each scored from 0 to 3 by the patient (0="without any difficulty", 1="with some difficulty", 2="with much difficulty", and 3="unable to do") and dividing the total raw score by 3. Pain and global estimate of health are measured on a likert scale from 0 to 10, both scored 0 (best) to 10 (worst). The three 0-10 scores for physical function, pain, and global assesment of health are added together for a composite score of 0 to 30. The RAPID3 composite score includes 4 categories: High Severity \> 12, Moderate Severity = 6.1 - 12, Low severity = 3.1 - 6, and Remission ≤ 3.

Count remission is achieved when a participant satisfies all of the following at any given time point: - 68 tender joint count ≤ 1, - 66 swollen joint count ≤ 1, - C-reactive protein (CRP) (in mg/dL) ≤1, and - patient global assessment of disease activity ≤ 1 (measured on a likert scale from 0 to 10 ranging from "no activity at all" to "worst activity imaginable").

The Clinical Disease Activity Index (CDAI) is a composite index that is calculated as the sum of the: * 28 tender joint count (TJC), * 28 swollen joint count (SJC), * Patient's Global Assessment of Disease Activity measured on a likert scale from 0 to 10, where 0 = lowest disease activity and 10 = highest; * Physician's Global Assessment of Disease Activity measured on a Likert scale from 0 to 10, where 0 = lowest disease activity and 10 = highest. The CDAI score ranges from 0-76 where lower scores indicate less disease activity. CDAI remission is defined as a score ≤ 2.8.

Population: Primary analysis set; LOCF was used. "N" indicates the number of participants included in the analyses at each time point.

The Clinical Disease Activity Index (CDAI) is a composite index that is calculated as the sum of the: * 28 tender joint count (TJC), * 28 swollen joint count (SJC), * Patient's Global Assessment of Disease Activity measured on a Likert scale from 0 to 10 where 0 = lowest disease activity and 10 = highest; * Physician's Global Assessment of Disease Activity (measured on a Likert scale from 0 to 10 where 0 = lowest disease activity and 10 = highest). The CDAI score ranges from 0 to 76 where lower scores indicate less disease activity.

The HAQ-DI asks about the degree of difficulty a person has in accomplishing tasks in 8 functional areas (dressing, arising, eating, walking, hygiene, reaching, gripping, and errands and chores). Responses in each functional area are scored from 0 indicating no difficulty to 3 indicating inability to perform a task in that area. The overall score is the average of each of the 8 category scores and ranges from 0 to 3, where zero represents no disability and three very severe, high-dependency disability.

Population: Primary analysis set; Mixed-Effect Model Repeated Measures (MMRM) analysis to account for post-baseline missing data with Likelihood-based approach was used. "N" indicates the number of participants included in the analyses at each time point.

The SF-36 measures the impact of disease on overall quality of life and consists of 36 questions in eight domains (physical function, pain, general and mental health, vitality, social function, physical and emotional health). The individual domain scores are calculated and transformed to range from 0 to 100, with higher scores indicating a better level of functioning. The physical functioning subscale assesses limitations in physical activities because of health problems. Least Squares means are from a mixed-effect model for repeated measurements (MMRM).

This self-administered questionnaire is designed to address impairment to the work productivity and activity of participants due to rheumatoid arthritis in the past 7 days. Percent of work time missed is derived from the number of hours of work missed due to rheumatoid arthritis symptoms as a percentage of total hours that should have been worked. A higher percentage indicates more hours missed. Least squares means are from a mixed-effect model for repeated measurements (MMRM).

The participant's assessment of fatigue was collected using a single-item 100 mm visual analogue scale. The participant was asked to draw a vertical line through a horizontal line to indicate the degree of fatigue they experienced because of their condition over the past week. The horizontal line is 100 mm in length with '0' and 'no fatigue' on the left end of the line and '100' and 'extreme fatigue' on the right end of the line.

Timeframe: Baseline and Weeks 4, 12 and 24

Population: Primary analysis set; Mixed-Effect Model Repeated Measures (MMRM) analysis to account for post-baseline missing data with Likelihood-based approach was used. "N" indicates the number of participants included in the analyses at each time point.

The MOS-Sleep comprises 12 items and measures key sleep structures across 6 domains. These domains are Sleep Disturbance (4 items), Sleep Adequacy (2 items), Sleep Quantity (1 item), Daytime Somnolence (3 items), Snoring (1 item), and Shortness of Breath (1 item). Sleep Disturbance measures the ability to fall asleep and to maintain restful sleep. In MOS Sleep norm-based scoring, all scales are scored on the same metric, where 50 is the mean for the general U.S. population and 10 is the standard deviation. Higher scores indicate more severe sleep problems. Least Squares means are from a mixed-effect model for repeated measurements (MMRM).

Sleep Adequacy measures sleep sufficiency in terms of whether the participant sleeps enough to provide restoration of wakefulness. In MOS Sleep norm-based scoring, all scales are scored on the same metric, where 50 is the mean for the general U.S. population and 10 is the standard deviation. For sleep adequacy a higher score indicates better sleep quality. Least Squares means are from a mixed-effect model for repeated measurements (MMRM).
