Summary

The purpose of this study is to assess the efficacy of abatacept after subcutaneous administration and intravenous administration in Japanese active rheumatoid arthritis (RA) subjects with inadequate response to methotrexate (MTX), and on background MTX in the short term.

Clinical Details

Official title: A Phase II/III, Multicenter, Randomized, Double-Blind, Double-Dummy Study to Assess Similarity of the Efficacy, Pharmacokinetics, Safety and Immunogenicity of Abatacept Administered Subcutaneously or Intravenously in Japanese Subjects With Rheumatoid Arthritis, Receiving Background Methotrexate, and Experiencing an Inadequate Response to Methotrexate

Study design: Allocation: Randomized, Endpoint Classification: Efficacy Study, Intervention Model: Parallel Assignment, Masking: Double Blind (Subject, Caregiver, Investigator, Outcomes Assessor), Primary Purpose: Treatment

Primary outcome: American College of Rheumatology (ACR) 20 response rates at 6 months of treatment of abatacept after subcutaneous administration and intravenous administration

Secondary outcome:

Efficacy: ACR 50 and ACR 70 response rates, Health Assessment Questionnaire (HAQ) and Disease Activity Score (DAS28) after 6 months of treatments

Pharmacokinetics: the trough level serum concentration of abatacept after subcutaneous administration and intravenous administration at the steady state

Anti-abatacept antibody and anti-cytotoxic T-lymphocyte antigen 4 (anti CTLA-4) antibody (immunogenicity) of abatacept after subcutaneous administration and intravenous administration in the short-term

Safety: the clinical adverse events (AEs) and adverse drug reactions (ADRs), vital signs and laboratory abnormalities of abatacept after subcutaneous administration and intravenous administration in the short-term

Eligibility

Minimum age: 20 Years. Maximum age: N/A. Gender(s): Both.

Criteria:

Inclusion Criteria:

- Subjects who are considered methotrexate inadequate responders

- 10 or more swollen joints (66 joint count) and 12 or more tender joints (68 joint

count)

Exclusion Criteria:

- Subjects who meet diagnostic criteria for any other rheumatic disease (eg, lupus

erythematous)

- Subjects with active vasculitis of a major organ system (except for subcutaneous

rheumatoid nodules)

- Subjects with severe chronic or recurrent bacterial infections
