What is Amgevita (adalimumab-atto)?
Amgevita (adalimumab-atto) is a prescription biological medicine used to treat a range of inflammatory conditions caused by an overactive immune system. It is a biosimilar version of Humira (adalimumab) and is considered to be highly similar with no clinically meaningful differences in safety or effectiveness for its approved uses. Amgevita works by blocking the action of tumor necrosis factor (TNF), a protein involved in causing inflammation.
Approved uses of Amgevita
Amgevita is approved to treat several chronic inflammatory conditions in adults and children. It is administered via subcutaneous injection. Specific uses include rheumatoid arthritis, psoriatic arthritis, ankylosing spondylitis, juvenile idiopathic arthritis, Crohn's disease, ulcerative colitis, plaque psoriasis, hidradenitis suppurativa, and uveitis. For a detailed list of indications, consult the resources provided.
How Amgevita works
Amgevita's mechanism of action involves its active ingredient, adalimumab-atto, a monoclonal antibody. It specifically targets and blocks tumor necrosis factor (TNF), a protein that plays a key role in the inflammation associated with many autoimmune diseases. By neutralizing TNF, Amgevita helps reduce inflammation and symptoms.
Comparison: Amgevita vs. Humira
Amgevita is a biosimilar of Humira, sharing the same active ingredient (adalimumab-atto vs. adalimumab) and mechanism of action (TNF-alpha blocker). While they treat many of the same adult inflammatory conditions, there are some differences, particularly in pediatric indications and available forms.
Feature | Amgevita (adalimumab-atto) | Humira (adalimumab) |
---|---|---|
Drug Type | Biosimilar of Humira | Reference biological drug |
Active Ingredient | Adalimumab-atto | Adalimumab |
Mechanism of Action | Same (TNF-alpha blocker) | Same (TNF-alpha blocker) |
Approved Adult Indications | Many of the same inflammatory conditions | Many of the same inflammatory conditions |
Approved Pediatric Indications | Approved for certain pediatric conditions (JIA, CD), but some differ from Humira | Broader pediatric approvals for some conditions, such as UC and HS |
Available Forms | Prefilled syringe and prefilled autoinjector | Prefilled syringe, prefilled pen, and vial |
Important safety information and risks
Before starting Amgevita, discuss all health conditions and medications with your doctor. Amgevita carries boxed warnings due to potential serious risks, including:
Boxed warnings
- Serious Infections: Increased risk of serious infections, including TB and other opportunistic infections. Screening for latent TB is required before treatment.
- Malignancy (Cancer): Increased risk of certain cancers, including lymphoma. A rare, fatal lymphoma has been reported, particularly in young males with IBD also on other immunosuppressants.
Other serious risks
- Hepatitis B reactivation in chronic carriers.
- New or worsening congestive heart failure.
- Nervous system problems like multiple sclerosis and Guillain-Barré syndrome.
- Lupus-like syndrome.
Common side effects
Common side effects may include injection site reactions, headache, upper respiratory infections, rash, nausea, and abdominal pain.
Who should avoid Amgevita?
Amgevita is not suitable for everyone. It is contraindicated in patients with an active severe infection (including active TB), a known allergy to adalimumab or other ingredients (some pens contain latex), or moderate to severe heart failure (NYHA class III/IV). It should not be used with other TNF blockers or specific immunomodulators like anakinra.
Conclusion
Amgevita, a biosimilar of Humira, treats inflammatory conditions by blocking TNF-alpha. Risks include serious infections and certain cancers due to its immunosuppressant action. Consultation with a healthcare provider is vital to determine if Amgevita is appropriate.
