What is Simlandi?

Simlandi (adalimumab-ryvk) is a biosimilar of Humira used to reduce pain, inflammation, and skin symptoms in autoimmune conditions plaque psoriasis, Crohn's disease, ulcerative colitis, rheumatoid arthritis, juvenile idiopathic arthritis, psoriatic arthritis, ankylosing spondylitis, hidradenitis suppurativa, and uveitis in certain patients.

Simlandi is a TNF alfa inhibitor and one of the interchangeable biosimilars to Humira. Biosimilars are biologic medicines that are a very close copy to the original product made by another company. An interchangeable biosimilar has undergone an additional Interchangeability Study, meaning that patients can be confident in the safety and effectiveness of the interchangeable biosimilar product, just as they would be for the FDA-approved original product, in this case, Humira. Being an interchangeable biosimilar means Simlandi can automatically be substituted by a pharmacist for Humira, with individual state laws controlling how and whether physicians will be notified.

Simlandi is used to treat chronic autoimmune conditions. Normally, your immune system defends your body against diseases by fighting harmful bacteria or viruses. However, in autoimmune disorders, the immune system becomes hyperactive and mistakenly attacks its own tissues, leading to symptoms of the autoimmune condition. Tumor necrosis factor (TNF) is a protein that is involved in causing inflammation. Sinlandi is a TNF blocker that inhibits TNF, helping to reduce pain, inflammation, and skin symptoms.

Simlandi is injected under the skin (subcutaneous injection) using an autoinjector or a prefilled syringe.
