🔬 What Is Yuflyma?

Yuflyma (adalimumab-aaty) is an FDA-approved biosimilar to Humira (adalimumab). A biosimilar is a biological medication that is highly similar to an already-approved reference biologic, with no clinically meaningful differences in safety, purity, or potency. Yuflyma (adalimumab-aaty) is a high-concentration (100 mg/mL), citrate-free Humira biosimilar from Celltrion. It uses a smaller injection volume which may reduce injection-site discomfort. It is approved for all Humira indications.

Yes. The FDA requires biosimilars to demonstrate there are no clinically meaningful differences in safety, purity, and potency compared to the reference product. Yuflyma underwent rigorous clinical studies demonstrating biosimilarity to Humira (adalimumab). Your prescriber can discuss whether Yuflyma is appropriate for your specific situation.

Many patients do switch from reference biologics to biosimilars. The decision should be made in consultation with your prescriber. Switching is generally safe for stable patients, but your doctor may want to monitor you during the transition. BiologicHealthPlus can coordinate the prior authorization for Yuflyma and ensure a seamless supply transition.

Most commercial insurance plans and Medicare Part D cover Yuflyma with prior authorization. In many cases, Yuflyma may have a lower tier placement on formularies than Humira (adalimumab), potentially reducing your copay. BiologicHealthPlus verifies your insurance coverage, handles all prior authorization, and enrolls you in the Celltrion Patient Support copay program to minimize your out-of-pocket costs.

Without insurance, Yuflyma costs approximately $1100/month at list price — lower than Humira (adalimumab)'s list price. Uninsured or underinsured patients may qualify for patient assistance through Celltrion Patient Support. BiologicHealthPlus will find every available savings option for you at no charge.
