An Efficacy and Safety Study of Golimumab in Patients With Active Rheumatoid Arthritis Despite Methotrexate Therapy

Phase 3

Completed

• Conditions: Rheumatoid Arthritis
• Interventions: Drug: Golimumab 50 mg; Drug: Golimumab 100 mg; Drug: Methotrexate; Drug: Placebo capsules; Drug: Placebo injection

• Registration Number: NCT00264550
• Lead Sponsor: Centocor, Inc.

Brief Summary

The purpose of this study is to evaluate the efficacy and safety of golimumab, alone or in combination with methotrexate (MTX), as compared to methotrexate alone in rheumatoid arthritis (RA) patients who have active rheumatoid arthritis despite treatment with MTX.

Detailed Description

This is a randomized (treatment is assigned by chance), double-blind (neither the physician nor the patient is aware of the received treatment), placebo-controlled study of multiple subcutaneous (SC) administrations of golimumab at 2 doses as monotherapy or in combination with MTX in patients with active RA despite treatment with MTX. The duration of participation in the study for an individual patient will be upto 268 weeks. The patients will be randomly assigned in a 3:3:2:2 ratio to receive golimumab 50 mg or 100 mg or placebo injections under the skin every 4 weeks through week 20 and methotrexate or placebo capsules will be given in addition. At Week 24, all subjects will receive golimumab 50mg or 100mg injections, and golimumab continues for all groups for about 4 and a half more years. At Week 16 any patient in the study who meets criteria for \< 20% improvement from baseline in both swollen and tender joint count will enter early escape in a double-blinded fashion. Treatment during the long-term extension will start at Week 52 and continue every 4 weeks thereafter for a total of approximately 5 years from the initial (Week 0) administration of study agent. Patients will return for scheduled follow-up visits generally every 12 weeks for a total length of follow-up of approximately 5 years from the first administration of the study drug.

Primary Outcome Measures

Name	Time	Method
Number of Participants Who Achieved American College of Rheumatology (ACR) 20 Response at Week 14	Week 14	ACR 20 response is defined as a greater than or equal to 20 percent improvement from baseline in: 1. Swollen joint count (66 joints) and tender joint count (68 joints) 2. greater than or equal to 50 percentage improvement in 3 of the following 5 assessments: a. Patient's assessment of pain of pain by the Visual Analogue Scale (VAS) (0-10 cm) b.Patient's Global Assessment of Disease activity VAS (0-10 cm) c. Physician's Global Assessment of Disease Activity VAS (0-10 cm) d. Patient's assessment of physical function as measured by the Health Assessment Questionnaire (HAQ) e. C reactive protein.
Change From Baseline in Health Assessment Questionnaire (HAQ) Score at Week 24	Baseline (Week 0) and Week 24	HAQ is 20-question instrument that assesses the degree of difficulty a person has in accomplishing tasks in 8 functional areas (dressing, arising, eating, walking, hygiene, reaching, gripping, and activities of daily living). Responses in each functional area are scored from 0 (no difficulty), to 3 (inability to perform a task in that area). The average score across the functional areas yields an overall HAQ score which ranges from 0 (no disability) to 3 (completely disabled).

Change From Baseline in Health Assessment Questionnaire (HAQ) Score at Week 14	Baseline (Week 0) and Week 14	The HAQ is 20-question instrument that assesses the degree of difficulty a person has in accomplishing tasks in 8 functional areas (dressing, arising, eating, walking, hygiene, reaching, gripping, and activities of daily living). Responses in each functional area are scored from 0 (no difficulty), to 3 (inability to perform a task in that area). The average score across the functional areas yields an overall HAQ score which ranges from 0 (no disability) to 3 (completely disabled).
Number of Participants With Disease Activity Index Score 28 (DAS 28) Using C-reactive Protein (CRP) Response at Week 14	Week 14	DAS 28 using CRP is an index to measure the disease activity in participants with rheumatoid arthritis which combines tender joint count (28 joints), swollen joint count (28 joints), CRP value, and participant's global assessment of disease activity (using a Visual Analog Scale of 0 to 100 mm). The DAS 28 score ranges from 0 (best) to 10 (worst). Participants are considered to have a DAS 28 response if they have a score of \<= 3.2 (good response) or \> 3.2 to 5.1 (moderate response).
Change From Baseline in Total Van Der Heijde Modified Sharp (vdH-S) Score at Week 24	Baseline (Week 0) and Week 24	The vdH-S score is the sum of joint erosion score and joint-space narrowing (JSN) score. The total score ranges from 0 (best) to 448 (worst) with higher scores indicating more joint damage.
