Trial overview
Official title: Clinical phase I/IIA study of subcutaneously administration of Ofatumumab in Rheumatoid Arthritis patients on stable dose Methotrexate
Trial description: 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 purpose:
Treatment
Trial design:
Parallel Assignment
Masking:
Single (Participant)
Allocation:
Randomized
Primary outcomes:
Safety and tolerability as described by the incidence and severity of adverse events [AEs], clinical laboratory parameters and vital signs.
Timeframe: throughout the study
Secondary outcomes:
Requirement for the use of pre-medication, including the timing, type and dose required.
Timeframe: throughout study
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.
Timeframe: throughout study
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.
Timeframe: throughout study
Immunogenicity as measured by the incidence, titre and type of human anti-human antibody (HAHA) immune response.
Timeframe: throughout study
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,
Timeframe: throughout study
Immunoglobulins (IgA, IgG, IgM), Complement (CH50, C3, C4), IgM Rheumatoid Factor (IgM-RF), IgA-RF and IgG-RF, anti-cyclic citrullinated peptide antibody (aCCP),
Timeframe: throughout study
serum amyloid A (SAA), CD-3+, CD-4+ and CD-8+ lymphocytes or other biomarkers, as data permit.
Timeframe: throughout study
Pharmacodynamics (B-cell depletion and re-population) as measured by CD-19 peripheral blood B- lymphocyte count via routine FACS analysis.Other Secondary Endpoints
