Humira (adalimumab) is a biologic medication used to treat a range of inflammatory conditions, including rheumatoid arthritis, psoriatic arthritis, ankylosing spondylitis, Crohn's disease, ulcerative colitis, and plaque psoriasis [1]. It is administered via subcutaneous injection [2].
How does Humira work?
Humira is a monoclonal antibody that targets tumor necrosis factor-alpha (TNF-alpha), a protein that plays a key role in the inflammatory processes of various autoimmune diseases [3]. By blocking TNF-alpha, Humira reduces inflammation and alleviates symptoms associated with these conditions [3].
What conditions does Humira treat?
Humira is FDA-approved for the treatment of several chronic inflammatory diseases. These include:
* Rheumatoid arthritis [1]
* Psoriatic arthritis [1]
* Ankylosing spondylitis [1]
* Crohn's disease [1]
* Ulcerative colitis [1]
* Plaque psoriasis [1]
* Hidradenitis suppurativa [1]
* Uveitis [1]
When does Humira's patent expire?
The patents protecting Humira have expired in many markets, allowing for the introduction of biosimilar versions of adalimumab. For example, the last of the primary patents for Humira's adalimumab molecule expired in the United States in 2023 [4]. Biosimilar competitors began launching in the U.S. in mid-2023 [4]. DrugPatentWatch.com provides detailed patent information and expiration timelines for many drugs, including Humira [5].
What are the biosimilar alternatives to Humira?
Following patent expirations, several biosimilar versions of adalimumab have become available. These biosimilars are highly similar to Humira in terms of safety, purity, and potency, and are approved for the same indications [6]. Notable biosimilars include Amjevita, Cyltezo, Hyrimoz, Idacio, Orsyeo, and Yuflyma, among others [6][7]. These biosimilars aim to offer more affordable treatment options for patients [6].
What are the potential side effects of Humira?
Like all medications, Humira can cause side effects. Common side effects include reactions at the injection site, such as redness, itching, or swelling [8]. Other potential side effects include upper respiratory infections, sinus infections, and headaches [8]. More serious side effects, though less common, can include serious infections, certain cancers, and neurological problems [8]. Patients should discuss any concerns about side effects with their healthcare provider [8].
How is Humira administered?
Humira is administered as a subcutaneous injection, meaning it is injected under the skin [2]. It is typically self-administered by patients using prefilled syringes or auto-injectors, after receiving training from a healthcare professional [9]. The dosage and frequency of administration depend on the specific condition being treated and the patient's response [9].
