Rheumatoid Arthritis, JNJ-38518168
Brief summary
The purpose of this study is to evaluate the efficacy, tolerability and safety of JNJ-38518168 compared with placebo in adult participants with active rheumatoid arthritis (long time systemic disease of the joints, marked by inflammatory changes in the synovial membranes and bones) despite methotrexate (MTX) therapy.
Detailed description
This is a multi-center (when more than 1 hospital or medical school team work on a medical research study), randomized (the study drug is assigned by chance), double-blind (neither physician nor participant knows the treatment that the participant receives), placebo-controlled (an inactive substance; a pretend treatment \[with no drug in it\] that is compared in a clinical trial with a drug to test if the drug has a real effect) and parallel-group (each group of participants will be treated at the same time) study. The study will consist of 3 phases; Screening phase (3 weeks), Treatment phase (12 weeks) and Follow-up phase (4 weeks). Each participant will be enrolled in the study for approximately 19 weeks. Participants with active rheumatoid arthritis despite MTX therapy will receive JNJ-38518168, 100 milligram (mg) per day or matching placebo capsules once daily for 12 weeks. Efficacy will be primarily evaluated by change from Baseline in disease activity index score C-reactive protein at Week 12. Participants' safety will be monitored throughout the study.

Inclusion criteria
* Participants diagnosed with rheumatoid arthritis (RA) according to the revised 1987 criteria of the ARA (Arnett et al, 1988) for at least 6 months at Screening * Participants who have been treated with and tolerated methotrexate (MTX) treatment at dosages from 7.5 to 25 milligram (mg) per week inclusive, for a minimum of 4 months before Screening * Participants if using non-steroidal anti-inflammatory drugs (NSAIDs) or other analgesics (drug used to control pain) regularly for RA, participants must have been on a stable dose for at least 2 weeks before the first dose of study medication * Participants if using oral corticosteroids (compounds, usually hormonal, taken orally \[by mouth\] in order to block ovulation \[discharge of an egg from the ovary\] and prevent the occurrence of pregnancy \[carrying an unborn baby\]), must be on a stable dose of less than or equal to 10 mg per day of prednisone or another oral corticosteroid for at least 4 weeks before the first dose of study medication and continue with the same dose throughout the study. If not using corticosteroids at study initiation, the participant must have not received any oral corticosteroids for at least 4 weeks before the first dose of study medication * Participants currently treated with folic acid at a minimum dose of 5 mg per week
Exclusion criteria
* Participants having inflammatory disease other than RA * Participant who have used any of the following medications: D-penicillamine, hydroxychloroquine, chloroquine, oral or parenteral gold salts, sulfasalazine, leflunomide, azathioprine, cyclosporine, tacrolimus, and mycophenolatemofetil * Participant who have received intra-articular, intramuscular (into the muscle), or intravenous (into the vein) corticosteroids, including adrenocorticotropic hormone (hormone made by the brain that activates the adrenal glands) within 4 weeks before the first dose of the study medication * Participants who have been treated with any other investigational drug or medical device within 4 weeks or 5 half-lives of the drug, whichever is longer before the first dose of study medication * Participants who have undergone surgical treatments for RA including synoviectomy (surgical removal of a part of the synovial membrane of a joint) and arthroplasty (surgery to fix a joint) within 3 months before the first dose of study medication
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Change From Baseline in Disease Activity Index Score (DAS28) C-Reactive Protein (CRP) at Week 12 | Baseline and Week 12 | The DAS28 based on CRP is a statistically derived index combining tender joints (28 joints), swollen joints (28 joints), CRP and participant's global assessment of disease activity. The set of 28 joint count is based on evaluation of the shoulder, elbow, wrist, metacarpophalangeal (MCP) MCP1 to MCP5, proximal interphalangeal (PIP) PIP1 to PIP5 joints of both the upper right extremity and the upper left extremity as well as the knee joints of lower right and lower left extremities. The values are 0=best to 10=worst. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Percentage of Participants With DAS28 (ESR) Response | Week 12 | The DAS28 based on erythrocyte sedimentation rate (ESR) is a statistically derived index combining tender joints (28 joints), swollen joints (28 joints), ESR and global health (GH). The DAS28-ESR is expressed on a score on a scale with the minimum score=0 (best) to maximum score=10 (worst). |
| Change From Baseline in DAS28 (ESR) Score at Week 12 | Baseline and Week 12 | The DAS28 based on ESR is a statistically derived index combining tender joints (28 joints), swollen joints (28 joints), ESR, and GH. The DAS28-ESR is expressed on a score on a scale with the minimum score=0 (best) to maximum score=10 (worst). |
| Percentage of Participants Achieving American College of Rheumatology (ACR20) Response | Week 12 | The ACR20 response is defined as more than or equal to (\>=) 20 percent improvement in swollen joint count (66 joints) and tender joint count (68 joints) and \>=20 percent improvement in 3 of following 5 assessments: participant's assessment of pain using Visual Analog Scale (VAS; 0-10 millimeter (mm), 0 mm=no pain and 10 mm=worst possible pain), participant's global assessment of disease activity by using VAS, physician's global assessment of disease activity using VAS, participant's assessment of physical function measured by Health Assessment Questionnaire-Disability Index (HAQ-DI) and CRP. |
| Percentage of Participants Achieving ACR50 Response | Week 12 | The ACR50 response is defined as \>=0 percent improvement in swollen joint count (66 joints) and tender joint count (68 joints) and \>=50 percent improvement in 3 of the following 5 assessments: participant's assessment of pain using VAS, participant's global assessment of disease activity by using VAS, physician's global assessment of disease activity using VAS, participant's assessment of physical function as measured by HAQ-DI and CRP. |
| Percentage of Participants With DAS28 (CRP) Response | Week 12 | The DAS28 based on CRP is a statistically derived index combining tender joints (28 joints), swollen joints (28 joints), CRP and participant's global assessment of disease activity. The set of 28 joint count is based on evaluation of the shoulder, elbow, wrist, MCP1 to MCP5, proximal PIP, PIP1 to PIP5 joints of both the upper right extremity and the upper left extremity as well as the knee joints of lower right and lower left extremities. The values are 0=best to 10=worst. |
| Change From Baseline in HAQ-DI at Week 12 | Baseline and Week 12 | The HAQ-DI is a 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 to 3 (0=no difficulty and 3=inability to perform a task in that area). |
| Change From Baseline in Participant's Assessment of Pain at Week 12 | Baseline and Week 12 | Participants will assess their average pain on a VAS. The scale ranges from 0 mm to 100 mm, (0 mm=no pain to 100 mm=worst possible pain). |
| Change From Baseline in Physician's Global Assessment of Disease Activity at Week 12 | Baseline and Week 12 | The Investigator's global disease assessments will be recorded on a VAS. The scale for the Investigator's assessments ranges from 0 mm to 100 mm (0 mm=no arthritis activity, 100 mm=extremely active arthritis). |
| Change From Baseline in Patient's Global Assessment of Disease Activity at Week 12 | Baseline and Week 12 | The participant's global disease assessments will be recorded on a VAS. The scale ranges from 0 mm to 100 mm (0 mm=very well to 100 mm=very poor). |
| ACR-N Index Score | Week 12 | The ACR-N Index of improvement is defined as the minimum of the following 3 criteria: percent improvement from Baseline in tender joint counts, percent improvement from Baseline in swollen joint counts and median percent improvement from Baseline for the following 5 assessments: participant's assessment of pain using VAS, participant's global assessment of disease activity using VAS, physician's global assessment of disease activity using VAS, participant's assessment of physical function as measured by HAQ-DI and CRP. Negative numbers indicate worsening. |
