Renflexis (infliximab-abda) is a tumor necrosis factor (TNF) blocker that is biosimilar to Remicade (infliximab).

According to the FDA, a biosimilar is shown to have no clinically meaningful differences in terms of safety and effectiveness from the reference product -- in this case Remicade. Only minor differences in clinically inactive components are allowable in biosimilar products.

What is the mechanism of action of infliximab?

Infliximab works by binding specifically to a protein called TNF-α (tumor necrosis factor-alpha), which is released by white blood cells as part of our body’s immune response to infection or foreign substances. Overproduction of TNF-α can cause inflammation which can damage tissues, bones, and cartilage, and also cell death. When infliximab binds to TNF-α, it blocks its effects, and this reduces inflammation. Increased levels of TNF-alfa have been found in conditions such as rheumatoid arthritis, psoriasis, and ankylosing spondylitis. Continue reading
