This study will examine the safety and tolerability, PK and PD of subcutaneously administered GSK1841157 in patients with RA on stable dose Methotrexate. The study comprises a single dose escalation/de-escalation phase to investigate the minimal efficacious dose based on PD markers with an acceptable safety profile.

Primary Outcome Measures:
  • Safety and tolerability as described by the incidence and severity of adverse events [AEs], clinical laboratory parameters and vital signs. [ Time Frame: throughout the study ] [ Designated as safety issue: Yes ]

Secondary Outcome Measures:
  • Requirement for the use of pre-medication, including the timing, type and dose required. [ Time Frame: throughout study ] [ Designated as safety issue: Yes ]
  • Pharmacodynamics (B-cell depletion and re-population) as measured by CD-19 peripheral blood B- lymphocyte count via routine fluorescent activated cell sorting (FACS) analysis. [ Time Frame: throughout study ] [ Designated as safety issue: No ]
  • PK/PD parameters including estimation of time to re-population of CD-19 peripheral blood B-cells to above LLQ (and/or <95% depletion) following single subcutaneous dose of Ofatumumab. [ Time Frame: throughout study ] [ Designated as safety issue: No ]
  • Immunogenicity as measured by the incidence, titre and type of human anti-human antibody (HAHA) immune response. [ Time Frame: throughout study ] [ Designated as safety issue: Yes ]
  • Other pharmacodynamic/biomarkers of disease activity and immune status may include high sensitivity C-reactive protein (hsCRP), Erythrocyte Sedimentation Rate (ESR), B-Lymphocyte Stimulator (BLyS/BAFF), B-Lymphocyte Chemokine (BLC), IL-6, [ Time Frame: throughout study ] [ Designated as safety issue: No ]
  • Immunoglobulins (IgA, IgG, IgM), Complement (CH50, C3, C4), IgM Rheumatoid Factor (IgM-RF), IgA-RF and IgG-RF, anti-cyclic citrullinated peptide antibody (aCCP), [ Time Frame: throughout study ] [ Designated as safety issue: Yes ]
  • serum amyloid A (SAA), CD-3+, CD-4+ and CD-8+ lymphocytes or other biomarkers, as data permit. [ Time Frame: throughout study ] [ Designated as safety issue: No ]
  • Pharmacodynamics (B-cell depletion and re-population) as measured by CD-19 peripheral blood B- lymphocyte count via routine FACS analysis.Other Secondary Endpoints [ Time Frame: throughout study ] [ Designated as safety issue: No ]
