A Study of Safety and Effectiveness of Golimumab in Participants With Active Rheumatoid Arthritis Despite Methotrexate Therapy

Centocor, Inc.643 enrolled

Overview

The purpose of this study is to assess the clinical effectiveness and safety of golimumab intravenous (IV) infusions every 12 weeks with or without Methotrexate (MTX), compared with MTX alone, in patients with active rheumatoid arthritis (RA) despite concurrent MTX treatment. In addition, the safety of subcutaneous (SC) golimumab injections following transition from IV golimumab infusions will also be evaluated.

This is a Phase III, double blind (neither investigator nor participant knows the treatment received), placebo-controlled (an inactive substance that is compared with the study medication to test whether the study medication has a real effect in clinical study), multicenter, 5-arm (treatment groups) study of golimumab at 2 doses (given with or without MTX over a period of 30 minutes) for at least 48 weeks in patients with active RA despite concurrent MTX therapy. The study consists of a treatment period of golimumab IV infusions (IV Period) which ranges from 48 weeks to approximately 140 weeks, assuming an enrollment period of approximately 92 weeks, and a long-term optional extension period (Extension Study) in which golimumab SC injections will be given for 24 weeks. The end of study will be the time the last participant completes the Week E-40 visit (Extension Study) for safety follow-up assessments. For the IV Period, participants will be randomly assigned to 1 of the 5 treatment groups in a 1:1:1:1:1 ratio (approximately 125 patients per group). At Week 16 and Week 24, joint assessment results will be used to allow participants to enter early escape and dose regimen adjustment, respectively, in a blinded fashion. Treatment will be unblinded after the 48-week database lock and participants will be given the option to participate in the Extension Study and receive SC injections of 50mg golimumab (with or without MTX) every 4 weeks for an additional 24 weeks. Safety will be monitored throughout the study. The entire study duration (IV Period plus Extension Study) for each participant will range from 88 weeks up to 192 weeks, assuming an enrollment period of approximately 92 weeks.

Outcomes

Primary Outcomes

Number of Participants With an American College of Rheumatology (ACR) 50 Response at Week 14

An ACR 50 response is defined as a greater than or equal to 50 percentage 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 (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 (CRP).

Time frame: Week 0 to Week 14

Secondary Outcomes

Number of Participants With an American College of Rheumatology (ACR) 50 Response at Week 24

ACR 50 response is an improvement of greater than or equal to 50 percentage from baseline in both the tender and swollen joint count and in at least 3 of the 5 assessments (patient's assessment of pain, patient's global assessemnt of disease activity, Physician's global assessment of disease activity (based on a scale of 0=no disease to 10=severe disease), HAQ (20 questions on life activities) and CRP blood test to measure inflammation).

Time frame: Week 0 to Week 24

Number of Participants With an American College of Rheumatology (ACR) 20 Response at Week 14

ACR 20 response is an improvement of greater than or equal to 20 percentage from baseline in both the tender and swollen joint count and in at least 3 of the 5 assessments (patient's assessment of pain, patient's global assessemnt of disease activity, Physician's global assessment of disease activity \[based on a scale of 0=no disease to 10=severe disease), HAQ (20 questions on life activities\] and CRP blood test to measure inflammation).

Time frame: Week 0 to Week 14

Number of Participants With a Disease Activity Index Score 28 (Using C-reactive Protein)Moderate or Good Response at Week 14

DAS28 using CRP is a measure of tender and swollen joints (28 joints each) and the patient's assessment of disease activity. Values range from 0 (best) to 10 (worst). A score of higher than 5.1 indicates high disease activity, and a score below 3.2 indicates low disease activity. A "Good" response is defined as a patient with a DAS28 score of \<= 3.2 at Week 14 with improvement from Baseline in DAS28 score of \> 1.2. A "Moderate" response is defined as a patient with DAS28 score of \>3.2-5.1 at Week 14 with improvement from baseline in DAS28 score of \>1.2 or a DAS28 score of \<= 5.1 and improvement from baseline in DAS28 score of \>0.6 to 1.2
