NCT ID: NCT00427934

Last Updated: 2014-11-05

Results Overview

A subject was an ACR 20 responder if: the counts for both tender and swollen joints had reduced by 20% or more from baseline; and 3 out of the following 5 assessments showed reduction of 20% or more from baseline assessment: Patient's Assessment of Arthritis Pain (Visual Analogue Scale \[VAS\]), Patient's Global Assessment of Arthritis (VAS), Physician's Global Assessment of Arthritis (Categorical), Health Assessment Questionnaire - Disability Index (HAQ-DI), and C-Reactive Protein (CRP).

PRIMARY outcome

Timeframe: Week 12

Population: Full Analysis Set (FAS) was defined as an intent-to-treat analysis set that included all subjects randomized to treatment who had taken at least 1 dose of study medication. Missing values were imputed by the method of last observation carried forward (LOCF).

A subject was an ACR 20 responder if: the counts for both tender and swollen joints had reduced by 20% or more from baseline; and 3 out of the following 5 assessments showed reduction of 20% or more from baseline assessment: Patient's Assessment of Arthritis Pain (Visual Analogue Scale \[VAS\]), Patient's Global Assessment of Arthritis (VAS), Physician's Global Assessment of Arthritis (Categorical), Health Assessment Questionnaire - Disability Index (HAQ-DI), and C-Reactive Protein (CRP).

Timeframe: Baseline, Weeks 1, 2, 4, 8, and 12

Population: FAS. Missing values were imputed by the method of LOCF.

Change from baseline at each visit was analyzed for tender/painful joint count. Twenty-eight tender and swollen joint scores included the same joints: shoulders, elbows, wrists, metacarpophalangeal joints (MCP), proximal interphalangeal joints (PIP), and the knees. The Week 16 visit (follow-up) was designed for safety rather than efficacy, thus Week 16 tender/painful joint count data were collected, but not analyzed.

The severity of arthritis was scored by the subject between 0 (no pain) and 100 (most severe pain) on a 100 mm VAS. Change from baseline at each visit was analyzed for Patient's Assessment of Arthritis Pain. The Week 16 visit (follow-up) was designed for safety rather than efficacy, thus Week 16 Patient's Assessment of Arthritis Pain data were collected, but not analyzed.

Population: FAS. Missing values were imputed by the method of LOCF.

Subjects answered: "Considering all the ways your arthritis affects you, how are you feeling today?" Subjects responded by using a 0 - 100 mm VAS where 0=very well and 100=very poorly. Change from baseline at each visit was analyzed for Patient's Global Assessment. The Week 16 visit (follow-up) was designed for safety rather than efficacy, thus Week 16 Patient's Global Assessment of Arthritis Pain data were collected, but not analyzed.

Population: FAS.

HAQ-DI assesses degree of difficulty experienced in daily activity categories (dressing/grooming, arising, eating, walking, hygiene, reach, grip and other activities) over the past week. There are 20 questions and difficulty is scored from 0 (none), 1 (some), 2 (much) and 3 (unable to do). Scores were then averaged to give the disability index (scale of 0 to 3). Change from baseline at each visit was analyzed. The Week 16 visit (follow-up) was designed for safety rather than efficacy, thus Week 16 HAQ-DI data were collected but not analyzed.

SECONDARY outcome

Timeframe: Baseline, Weeks 1, 2, 4, 8, and 12

Population: FAS. Missing values were imputed by the method of LOCF.

DAS28-4 (CRP) was calculated using the following formula: DAS28- 4(CRP) = 0.56 √28 Tender Joint Count + 0.28 √28 Swollen Joint Count + 0.36\*natural logarithm(CRP + 1) + 0.014\*Patient Global Assessment + 0.96. DAS28 provides a number on a scale (0 to 10) indicating current disease activity. A score above 5.1 means high disease activity and a score below 3.2 indicates low disease activity. Change from baseline at each visit was analyzed for DAS28-4 (CRP). The Week 16 visit (follow-up) was designed for safety rather than efficacy, thus Week 16 DAS28-4 (CRP) data were collected, but not analyzed.

SECONDARY outcome

Timeframe: Baseline, 16 weeks

Population: FAS

Supine BP was recorded after 5 minutes lying down; subjects then sat for 2 minutes then stood for 2 minutes and standing BP was recorded. Orthostatic BP = either a systolic BP drop \> 20 mmHg, or diastolic BP drop \> 10 mmHg and/or drop in systolic BP \< 90 mmHg. If a subject met the orthostatic criteria, they were required to complete 2 additional readings to provide a triplicate reading. The means of replicate BP values were used in the analysis. Baseline = the latest non-missing value from a range of pre-treatment visits. Change from baseline to Week 16 was analyzed for orthostatic BP.

The SF-36 v.2 (Acute version) is a 36-item generic health status measure that measures 8 general health concepts: Physical functioning, role-physical, bodily pain, general health, vitality, social functioning, role-emotional, and mental health. Each domain of the eight domains and the summary concept (physical component score) are scored to yield values between 0 (worst) and 100 (best). Change from baseline at Weeks 4 and 12 were analyzed for SF-36. Due to the termination of the study, SF-36 results for the PK component group were not analyzed.
