Study to Evaluate SC Route of Administration of Ofatumumab in RA Patients

This study has been completed.
Sponsor:
Information provided by (Responsible Party):
GlaxoSmithKline
ClinicalTrials.gov Identifier:
NCT00686868
First received: May 28, 2008
Last updated: June 23, 2017
Last verified: June 2017
  Purpose
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.

Condition Intervention Phase
Arthritis, Rheumatoid Other: placebo Drug: ofatumumab Phase 1

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Participant
Primary Purpose: Treatment
Official Title: Clinical Phase I/IIA Study of Subcutaneously Administration of Ofatumumab in Rheumatoid Arthritis Patients on Stable Dose Methotrexate

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 ]

Secondary Outcome Measures:
  • Requirement for the use of pre-medication, including the timing, type and dose required. [ Time Frame: 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. [ Time Frame: 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. [ Time Frame: throughout study ]
  • Immunogenicity as measured by the incidence, titre and type of human anti-human antibody (HAHA) immune response. [ Time Frame: 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, [ Time Frame: 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), [ Time Frame: throughout study ]
  • serum amyloid A (SAA), CD-3+, CD-4+ and CD-8+ lymphocytes or other biomarkers, as data permit. [ Time Frame: 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 [ Time Frame: throughout study ]
