Overview
Brief Summary
This is a multicentre, randomised, double-blind, parallel group study to compare the pharmacokinetics (PK), pharmacodynamics (PD), immunogenicity, safety, tolerability and efficacy of JHL1101 versus MabThera in subjects with moderate to severe RA who have previously failed at least 1 tumour necrosis factor alpha (TNF) inhibitor (i.e., intolerance or documented active disease despite at least 12 weeks treatment according to the TNF inhibitor-approved treatment and dosage), and are on concomitant treatment with MTX.
Detailed Description
This study will take place across approximately 31 centres across 12 countries and will randomise approximately 150 subjects as outpatients. The primary objective is to investigate and compare the pharmacokinetic profiles of JHL1101 and MabThera (rituximab). The secondary objectives are to investigate the safety, tolerability, and immunogenicity of JHL1101 versus MabThera, to investigate the pharmacodynamics profile of JHL1101 versus MabThera, and investigate the efficacy of JHL1101 versus MabThera.

Eligibility Criteria
Inclusion Criteria
- •Moderate to severe active RA
- •Documented intolerance to or inadequate response to at least 12 weeks of treatment with the licensed regimen of at least one TNF inhibitor therapy
- •Women of childbearing potential must use a medically acceptable means of birth control and agree to continue its use during the study and for at least twelve months after the last dose of study drug.
Exclusion Criteria
