Summary

This study is a randomised, single-blind, placebo-controlled, repeat dose study of otelixizumab administered subcutaneously in rheumatoid arthritis patients. One cohort will receive a single dose of adalimumab (HUMIRA, Abbott) as rescue medication to assess additional concomitant safety and tolerability issues.

Detailed description

Otelixizumab is a humanized, aglycosyl, non-mitogenic, anti CD3 monoclonal antibody (MAb) directed against the ε domain of the human lymphocyte antigen CD3, which is currently undergoing phase III clinical trials in adult new-onset type I diabetes mellitus patients and has been evaluated in rheumatoid arthritis and psoriasis patients in small exploratory studies. Otelixizumab has been administered via the subcutaneous route as a single dose in type I diabetes patients. This study is a randomised, single-blind, placebo-controlled, repeat dose study of otelixizumab administered subcutaneously in rheumatoid arthritis patients. One cohort will receive a single dose of adalimumab (HUMIRA, Abbott) as rescue medication to assess additional concomitant safety and tolerability issues. This study will consist of a screening phase, followed by an in-house phase whereby otelixizumab will be administered to cohorts in a staggered fashion. Six cumulative doses will be evaluated covering a 10-fold dose range in seven cohorts. The starting regimen will be three doses (1.5 mg cumulative dose), increasing to 15 doses (15 mg cumulative dose). Cohorts 1a and 1b have been included as optional lower doses. Serial blood samples will be obtained for clinical laboratory testing, determination of pharmacodynamic markers, serum otelixizumab PK parameters, and immunogenicity. Safety and pharmacodynamic data from the previous dose(s) will be evaluated prior to dose escalation or modification to ensure safety and to achieve target systemic peripheral blood pharmacology. Adverse events, laboratory values, vital signs and ECG's will be monitored closely during this study. All subjects in the study will undergo long-term follow-up out to 48 months to monitor and ensure patient safety.
