Simlandi (Adalimumab-Ryvk) for Hidradenitis Suppurativa

Overview
Simlandi is approved by the U.S. Food and Drug Administration (FDA) for the treatment of moderate to severe hidradenitis suppurativa (HS) in adults, along with various other chronic autoimmune conditions. Simlandi is a biosimilar of Humira (Adalimumab). As defined by the FDA, a biosimilar is a biological product that is approved based on a showing that it is highly similar to an already-approved biological product. Simlandi is also known by its drug name, adalimumab-ryvk.

Simlandi belongs to a class of drugs known as tumor necrosis factor (TNF) blockers. It is thought to work by inhibiting the action of a cytokine (chemical messenger) in the body called tumor necrosis factor, which is involved in inflammation and immune system activity in conditions such as psoriasis and PsA. By inhibiting TNF, Simlandi can reduce inflammation and other symptoms associated with HS.

How do I take it?
According to the drug’s prescribing information, Simlandi is administered as a subcutaneous (under the skin) injection. Treatment of hidradenitis suppurativa generally starts with an initial dose on Day 1 (given in one day or split over two consecutive days), followed by a dose on Day 15. Starting from Day 29 and for subsequent doses, a person may receive a dose every week or every other week. The medication should be taken exactly as prescribed by a health care provider.
