Switching from reference infliximab to biosimilars (infliximab-abda and infliximab-dyyb) for rheumatic diseases may lead to treatment delays and a higher risk of disease flares, particularly when the switch is mandated by insurance.
The FDA designates 2 biosimilars as interchangeable, enhancing access to treatments for inflammatory diseases and multiple sclerosis, while 2 other companies expand their biosimilar partnership to include more products.
Despite a dramatic shift toward biosimilar use following British Columbia’s policy, researchers found no rise in hospital visits or complications, underscoring the real-world reliability of etanercept biosimilars in managing inflammatory arthritis.
