Lasso di tempo: At Weeks 12, 24, 36, 48, 60, 72, 78

Disease Activity Score (DAS) based on a 28 joint count hsCRP consisted of composite numerical score of following variables: tender joint count (TJC28), swollen joint count (SJC28), hsCRP (mg/mL), and participant's global assessment of disease activity. DAS28-hsCRP was calculated using following formula: DAS28-hsCRP equals to (=) 0.56*square root (sqrt) (TJC28) plus (+) 0.28*sqrt (SJC28) + 0.36*natural log(hsCRP+1) + 0.014*participant's global assessment of disease activity + 0.96. Scores ranged 0-9.4, where lower scores indicated less disease activity.

Lasso di tempo: At Weeks 12, 24, 36, 48, 60, 72, 78

The DAS28 (CRP) is a composite index used to assess rheumatoid arthritis disease activity, calculated based on the tender joint count (out of 28 evaluated joints), swollen joint count (out of 28 evaluated joints), Patient's Global Assessment of Disease Activity (measured on a VAS from 0-100 mm), and hsCRP (in mg/L). Scores on the DAS28 (CRP) range from 0 to approximately 10, where higher scores indicate more disease activity.

Clinical remission is defined as a DAS28(CRP) score < 2.6.

Lasso di tempo: Baseline (of the preceding TLL-018-301 study)and Weeks 12, 24, 36, 48, 60, 72, 78

The disease activity score-28-CRP (DAS28 [CRP]) assesses RA disease activity based on a continuous scale of combined measures of 28 tender joint counts (TJC28), 28 swollen joint counts (SJC28), C-reactive protein (CRP), and the patient global assessment of disease activity (measured on a visual analog scale from 0 to 100 mm). DAS28(CRP) scores range from 0 to approximately 10 where higher scores indicate more disease activity. A negative change from Baseline in DAS28 (CRP) indicates improvement in disease activity.

Lasso di tempo: Baseline (of the preceding TLL-018-301 study)and Weeks 12, 24, 36, 48, 60, 72, 78

The Health Assessment Questionnaire - Disability Index is a patient-reported questionnaire that measures 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) over the past week. Participants assessed their ability to do each task on a scale from 0 (without any difficulty) to 3 (unable to do). Scores were averaged to provide an overall score ranging from 0 to 3, where 0 represents no disability and 3 represents very severe, high-dependency disability.

Lasso di tempo: Baseline (of the preceding TLL-018-301 study)and Weeks 12, 24, 36, 48, 60, 72, 78

The clinical disease activity index (CDAI) is a composite index for assessing disease activity based on the summation of the counts of tender joint count (out of 28 evaluated joints) and swollen joint count (out of 28 evaluated joints), Patient's Global Assessment of Disease Activity measured on a VAS from 0 to 10 cm, and Physician's Global Assessment of Disease Activity measured on a VAS from 0 to 10 cm. The total CDAI score ranges from 0 to 78 with higher scores indicating higher disease activity. A negative change from Baseline indicates improvement in disease activity.

Lasso di tempo: Baseline (of the preceding TLL-018-301 study)and Weeks 12, 24, 36, 48, 60, 72, 78

The simplified disease activity index (SDAI) is a composite index for assessing disease activity based on the summation of the counts of tender joint count (out of 28 evaluated joints) and swollen joint count (out of 28 evaluated joints), Patient's Global Assessment of Disease Activity measured on a VAS from 0 to 10 cm, Physician's Global Assessment of Disease Activity measured on a VAS from 0 to 10 cm and hsCRP (mg/dL). The total SDAI score ranges from 0 to 86 with higher scores indicating higher disease activity. A negative change from Baseline indicates improvement in disease activity.

Change From Baseline in Patient's Assessment of Pain Over Time
Lasso di tempo: Baseline (of the preceding 301 study)and Weeks 12, 24, 36, 48, 60, 72, 78

Participants were asked to indicate the severity of their arthritis pain within the previous week on a visual analog scale from 0 to 100 mm. A score of 0 mm indicates "no pain" and a score of 100 mm indicates "worst possible pain."

Lasso di tempo: Baseline (of the preceding TLL-018-301 study)and Weeks 12, 24, 36, 48, 60, 72, 78

The participant was asked to rate their current RA disease activity over the past 24 hours on a 100 mm VAS, where 0 mm indicates very low disease activity and 100 mm indicates very high disease activity.

Changes From Baseline in SF-36 Score Over Time
Lasso di tempo: Baseline (of the preceding TLL-018-301 study)and Weeks 24, 48, 78

SF-36 score was an evaluation of the functional status for a participant,taping eight health concepts: physical functioning, bodily pain, role limitations due to physical health problems, role limitations due to personal or emotional problems, emotional well-being, social functioning, energy/fatigue, and general health perceptions. Coded numeric values are recoded per the scoring key. All items are scored so that a high score defines a more favorable health state. Each item is scored on a o to 100 range. Items in the same scale are averaged together to create the 8 scale scores.

The VAS is a 100 mm line ranging from 0 mm (no morning stiffness) on the left end and 100 mm (worst morning stiffness) on the right end. Subjects marked on the line to indicate their pain severity. The distance in mm was measured from the left end to the subject's marking. Duration of morning stiffness will be from wake-up time to time of resolution of morning stiffness.
