Arthritis, Rheumatoid
Conditions
Brief summary
This is a 2-part (6 weeks duration for each part), randomized, double-blind, placebo-controlled study in participants with rheumatoid arthritis. The hypothesis is that etoricoxib (60 mg and 90 mg) administration will demonstrate superior efficacy compared to placebo after 6 weeks of treatment, as measured by the greater mean improvement from baseline in the Disease Activity Score C-Reactive Protein (DAS-28 CRP), and by the greater mean improvement in Patient Global Assessment of Pain (PGAP) from baseline over 6 weeks of treatment. Additionally, the added benefit of increasing the dose of etoricoxib from 60 mg to 90 mg will be assessed in the second part of the study.

| Time-Weighted Average Change From Baseline in DAS28-CRP in Part 1 (Etoricoxib vs. Placebo) | Baseline and Week 6 | Disease Activity Score Using C-Reactive Protein \[DAS28-CRP\] (0 - 10 Range). The DAS28-CRP index is a composite score of weighted components including tender joint counts of 28, swollen joint counts of 28, patient global assessment of disease activity, and C-reactive protein (CRP). For each observation (Baseline, Week 2, 4, 6, 10, 12), components were combined into a single DAS28-CRP score using the following algorithm: 0.56\*square root (sqrt) (tender joint count \[28\])+0.28\*sqrt(swollen joint count \[28\] )+0.36\* ln(crp+1) + 0.014\* Patient Global Assessment of Disease Activity + 0.96. The primary objectives of the study compared the efficacy of etoricoxib (90 mg, 60 mg) to placebo in Part 1 of this study so data for only these 3 arms are displayed. |
| Time-Weighted Average Change From Baseline in Patient Global Assessment of Pain in Part 1 (Etoricoxib vs. Placebo) | Baseline and Week 6 | A participant overall assessment of pain on a visual analog scale (VAS) was assessed with a question concerning the amount of pain due to arthritis during the past 48 hours. Pain was assessed on an 100 mm VAS scale with a left-hand marker no pain (0 mm) or right-hand marker extreme pain (100 mm). The primary objectives of the study compared the efficacy of etoricoxib (90 mg, 60 mg) to placebo in Part 1 of this study so data for only these 3 arms are displayed. |
| Percentage of Participants Who Experienced at Least One Adverse Event (AE) | Up to 112 days | An AE is defined as any unfavorable and unintended sign including an abnormal laboratory finding, symptom or disease associated with the use of a medical treatment or procedure, regardless of whether it is considered related to the medical treatment or procedure. |
| Percentage of Participants Who Discontinued Study Drug Due to an AE | Up to Week 12 | An AE is defined as any unfavorable and unintended sign including an abnormal laboratory finding, symptom or disease associated with the use of a medical treatment or procedure, regardless of whether it is considered related to the medical treatment or procedure. |

Pain was assessed on an 100 mm VAS scale with a left-hand marker no pain (0 mm) or right-hand marker extreme pain (100 mm).

| Average Change From Week 6 in Patient Global Assessment of Pain Over Weeks 10 and 12 in Part 2 Among Pain Inadequate Responders From Part 1 | Week 6 and Week 10 to Week 12 | A participant overall assessment of pain on a visual analog scale (VAS) was assessed with a question concerning the amount of pain due to arthritis during the past 48 hours. Pain was assessed on an 100 mm VAS scale with a left-hand marker no pain (0 mm) or right-hand marker extreme pain (100 mm). In those participants who were considered inadequate responders to etoricoxib 60 mg in Part 1 (defined as a participant with \<50% improvement from baseline in PGAP \[VAS\] at Week 6), the incremental benefit of increasing the etoricoxib dose from 60 mg (in Part 1) to 90 mg (in Part 2) compared to remaining on 60 mg in Part 2 was evaluated via average change from Week 6 over Weeks 10 and 12 in Patient Global Assessment of Pain score. Therefore, data for only these 2 arms are displayed. |

Time-Weighted Average Change From Baseline in DAS28-CRP in Part 1 (Etoricoxib vs. Placebo)
Disease Activity Score Using C-Reactive Protein \[DAS28-CRP\] (0 - 10 Range). The DAS28-CRP index is a composite score of weighted components including tender joint counts of 28, swollen joint counts of 28, patient global assessment of disease activity, and C-reactive protein (CRP). For each observation (Baseline, Week 2, 4, 6, 10, 12), components were combined into a single DAS28-CRP score using the following algorithm: 0.56\*square root (sqrt) (tender joint count \[28\])+0.28\*sqrt(swollen joint count \[28\] )+0.36\* ln(crp+1) + 0.014\* Patient Global Assessment of Disease Activity + 0.96. The primary objectives of the study compared the efficacy of etoricoxib (90 mg, 60 mg) to placebo in Part 1 of this study so data for only these 3 arms are displayed.
Time frame: Baseline and Week 6
Population: The modified intention-to-treat (mITT) population in Part 1 consisted of all randomized participants receiving at least 1 dose of study medication, had baseline data for the analysis endpoint, and least one post-randomization measurement for the analysis endpoint that was collected within 3 days after the last dose of study medication.

Average Change From Week 6 in Patient Global Assessment of Pain Over Weeks 10 and 12 in Part 2 Among Pain Inadequate Responders From Part 1
A participant overall assessment of pain on a visual analog scale (VAS) was assessed with a question concerning the amount of pain due to arthritis during the past 48 hours. Pain was assessed on an 100 mm VAS scale with a left-hand marker no pain (0 mm) or right-hand marker extreme pain (100 mm).
