Brief Summary:
The hypothesis of this study is that subcutaneous Abatacept is effective in reducing synovial inflammation, osteitis, and erosions in Rheumatoid Arthritis as assessed by low field extremity MRI and X-ray.

Condition or disease Intervention/treatment Phase
Rheumatoid Arthritis Biological: Subcutaneous Abatacept Phase 2 Phase 3

Detailed Description:

This is an open-label study of the efficacy of subcutaneous (SC) Abatacept to inhibit progression of structural joint damage in patients with active rheumatoid arthritis (RA) receiving MTX and have inadequate disease control (defined as an ESR based DAS28 ≥ 3.2 AND ≥ 6 swollen and ≥ 6 tender joints). The study consists of a screening period (Days -21 to -7), a baseline visit (Days -20 to -1), and a treatment Period (open label Abatacept 125 mg SC for 24 weeks). All the visits may occur at the indicated week +/- 2 days. The last efficacy assessments are to be conducted at Week 24 and subjects are to be contacted by telephone for a safety follow-up 2 months after the final study agent has been administered.

The maximum length of the study is 35 weeks, which includes the 2-week screening period, 1-week baseline period, 24-week open label treatment, and 8-week follow-up period. Eligible subjects are to continue their current MTX treatment regimen, a stable dose of at least 15mg/week, during the entire length of the study (24 weeks). At Day 0, patients who meet inclusion criteria, will be dosed from Day 0 to Week 24 with Abatacept 125 mg SC injection.

Subjects are to self-administer SC study agent at Weeks 5, 6, 7, 9, 10, 11, 13, 14, 15, 17, 18, 19, 21, 22, and 23 and are not required to return to the study site at these weeks. All other visits, SC study agent is to be administered while the subject is at the study site.

Drug Information available for: Abatacept

Arm Intervention/treatment
Experimental: Open-Label Subcutaneous Abatacept
Open-Label Subcutaneous Abatacept
Biological: Subcutaneous Abatacept
Subcutaneous Abatacept 125 mg once weekly for 6 months

Primary Outcome Measures :
  1. Inhibition & progression of structural damage [ Time Frame: 6 months ]
    Assess inhibition & progression of structural damage in MTX inadequate responders with moderate to severe active RA on SC Abatacept plus MTX, utilizing eMRI and X-ray at baseline, eMRI at Week 12, and eMRI and X-ray final assessment at week 24.

Secondary Outcome Measures :
  1. Improvement in ESR-based DAS28 [ Time Frame: 6 months ]
    Assess improvement in ESR-based DAS28, physician global assessment, and improvement in HAQ score

Layout table for eligibility information
Ages Eligible for Study:   18 Years and older   (Adult, Older Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  1. Subjects currently experiencing active moderate to severe RA according to the revised 1987 ACR criteria for the diagnosis of RA at screening. The ESR-based DAS 28 must be equal or greater than 3.2
  2. MTX inadequate responders with moderate to severe RA. Subjects currently receiving MTX for at least 12 weeks and who have received MTX at a stable dose (≥15mg/week) for at least 6 weeks prior to treatment (Day 0). They must be biologic drug naive
  3. All subjects must receive at least 5 mg oral folic acid weekly.
  4. At screening active RA as defined by ≥ 6 swollen joints and ≥ 6 tender joints with erythrocyte sedimentation rate (ESR) ≥ 28 mm/h.
  5. Subjects must be seropositive with documented rheumatoid factor (RF) or anti-cyclic citrullinated peptide (anti CCP) positivity. If a documented history of RF or anti CCP positivity is not available, RF and anti CCP titers will be obtained at screening
  6. MRI evidence of at least one joint with osteitis or erosion attributable to RA as determined by an MRI musculoskeletal radiologist. Any joint of the dominant hand or wrist can be considered with the exception of distal interphalangeal joints of the hands.
  7. If subjects are receiving an oral corticosteroid, the dose must be ≤10 mg/day prednisone (or equivalent) and stable for at least 28 days prior to treatment (Day 0).
  8. Subjects able and willing to give written informed consent and comply with the requirements of the study protocol. Informed consent must be obtained prior to any study-related procedures.

    A copy of the signed informed consent form must be given to the subject

  9. Subjects must be willing to self-inject or allow a caregiver to administer the subcutaneous injection
