Summary

This trial tests the safety and tolerability of imvotamab, a new medication, in adults with severe rheumatoid arthritis who haven't responded to other treatments. The study will help understand how the drug works in the body and its effects on inflammation.

Who is the study for?
Adults over 18 with moderate to severe rheumatoid arthritis who haven't responded well to at least two different biologic or targeted synthetic DMARDs. Participants should have active disease, shown by a certain number of swollen and tender joints and high inflammation markers in blood tests. They shouldn't have other autoimmune diseases (except secondary Sjögren's syndrome) or be on high doses of steroids.
What is being tested?
The trial is testing the safety and effects of Imvotamab, an experimental medication for rheumatoid arthritis, compared to a placebo. The drug or placebo is given intravenously. The goal is to see if Imvotamab can help people who didn't get better with previous treatments.
What are the potential side effects?
While specific side effects for Imvotamab are not listed, common side effects for drugs treating rheumatoid arthritis may include injection site reactions, increased risk of infections, headaches, nausea, and potential allergic reactions.

Mechanism Of Action
Side Effect Profile
Prior Approvals
Other Research
Common treatments for Rheumatoid Arthritis (RA) include biologics and immunomodulatory drugs. Biologics, such as TNF inhibitors (e.g., infliximab) and IL-6 inhibitors, work by targeting specific components of the immune system that drive inflammation and joint damage. Immunomodulatory drugs like methotrexate suppress the overall immune response to reduce inflammation. These treatments are crucial for RA patients as they help manage symptoms, prevent joint damage, and improve quality of life. The study of Imvotamab, likely a biologic, aims to offer another targeted approach for patients who have not responded to existing therapies.
