|
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.

Change From Baseline in Disease Activity Score Using CRP (DAS28-4[CRP]) at Weeks 1, 2, 4, 8, and 12
Time Frame: Baseline, Weeks 1, 2, 4, 8, and 12
|
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. |
Baseline, Weeks 1, 2, 4, 8, and 12
|
Change From Baseline in Mean Orthostatic Blood Pressure (BP)
Time Frame: Baseline, 16 weeks
|
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.

Survival Analysis of Time to Withdrawal: Proportion of Subjects Who Did Not Withdraw From the Study Due to Lack of Efficacy.
Time Frame: Weeks 1 to 12

Withdrawal due to lack of efficacy was collected based on the investigator's judgement.
Time to withdrawal was measured by the probability that a subject did not withdraw due to lack of efficacy by a particular visit.
This was a statistical estimate (Kaplan-Meier Survival Analysis) of the probability that a participant would not withdraw due to lack of efficacy.
