What is the difference between Amjevita and Humira?
Amjevita (adalimumab-atto) is a biosimilar to Humira (adalimumab), an anti-TNF-α monoclonal antibody used for the treatment of multiple conditions including rheumatoid arthritis, juvenile idiopathic arthritis, psoriatic arthritis, ankylosing spondylitis, Crohn’s disease, ulcerative colitis, plaque psoriasis, and hidradenitis suppurativa.
A biosimilar is a product that is highly similar to an FDA-approved biologic, known as the reference product. Biosimilars have no clinically meaningful differences in safety, purity or potency compared to the reference product.
Amjevita (adalimumab-atto) was the first Humira (adalimumab) biosimilar approved by the FDA.
FDA approved biosimilars to Humira include:
- Amjevita (adalimumab-atto)
- Cyltezo (adalimumab-adbm)
- Hyrimoz (adalimumab-adaz)
- Hadlima (adalimumab-bwwd)
- Abrilada (adalimumab-afzb)
- Hulio (adalimumab-fkjp)
- Yusimry (adalimumab-aqvh)
- Idacio (adalimumab-aacf)
- Yuflyma (adalimumab-aaty)
