Study of an Anti-TLR4 mAb in Rheumatoid Arthritis

Phase 2
Completed
Conditions
Rheumatoid Arthritis
Interventions
Other: Placebo
Registration Number
NCT03241108
Lead Sponsor
Light Chain Bioscience - Novimmune SA
Brief Summary

This is a Phase 2, PoC, randomized, placebo-controlled, double blind, international multicentre study to explore the effect of a new antibody to treat patients with Rheumatoid Arthritis

Detailed Description

The study foresees the randomization of at least 81 moderate to severe, ACPA positive, RA patients who are inadequate responders to MTX, in two double blind arms (NI-0101:placebo, with a ratio of 2:1). Patients will receive NI-0101 or placebo infusions up to a maximum of 6 administrations (every two weeks for 12 weeks). All patients will continue receiving a stable dose of MTX. After 12 weeks, patients will enter the follow up period with monthly visits for a minimum of 12 weeks.
