A Two-Part, 12-Week Study of Etoricoxib as a Treatment for Rheumatoid Arthritis (RA) (MK-0663-107)

June 5, 2024 updated by: Organon and Co

A Phase III, Two-Part, Randomized, Double-Blind, Placebo-Controlled, Multicenter Clinical Trial to Assess the Relative Efficacy and Tolerability of Two Doses of MK-0663/Etoricoxib in Patients With Rheumatoid Arthritis

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.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Time-Weighted Average Change From Baseline in DAS28-CRP in Part 1 (Etoricoxib vs. Placebo)
Time Frame: 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.
Baseline and Week 6
Time-Weighted Average Change From Baseline in Patient Global Assessment of Pain in Part 1 (Etoricoxib vs. Placebo)
Time Frame: 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.
Baseline and Week 6
Percentage of Participants Who Experienced at Least One Adverse Event (AE)
Time Frame: 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.
Up to 112 days
Percentage of Participants Who Discontinued Study Drug Due to an AE
Time Frame: 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.
Up to Week 12

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Time-Weighted Average Change From Baseline in DAS28-CRP in Part 1 (Etoricoxib 90 mg vs. Etoricoxib 60 mg)
Time Frame: 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 key secondary objectives compared the relative efficacy between etoricoxib 90 mg and 60 mg in Part 1 of this study so data for only these 2 arms are displayed.
Baseline and Week 6
Time-Weighted Average Change From Baseline in Patient Global Assessment of Pain in Part 1 (Etoricoxib 90 mg vs. Etoricoxib 60 mg)
Time Frame: 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 key secondary objectives compared the relative efficacy between etoricoxib 90 mg and 60 mg in Part 1 of this study so data for only these 2 arms are displayed.
Baseline and Week 6
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
Time Frame: 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.
Week 6 and Week 10 to Week 12
