Introduction
Brodalumab is a human monoclonal antibody to the interleukin-17A receptor which acts as an immunosuppressant and is used to treat moderate-to-severe plaque psoriasis. Brodalumab has not been linked to serum enzyme elevations during therapy or to instances of idiosyncratic acute liver injury.
Background
Brodalumab (broe dal' ue mab) is a recombinant, human IgG monoclonal antibody to the interleukin (IL)-17A receptor, engagement of which results in release of proinflammatory mediators. The binding of the monoclonal antibody blocks the interaction of IL-17A with its receptor and thus decreases inflammatory pathways that are involved in immune mediated cell injury. Brodalumab is considered an immunomodulatory agent and has been evaluated in several immune mediated diseases including inflammatory bowel disease, rheumatoid arthritis and psoriasis. In large clinical trials of moderate-to-severe plaque psoriasis, brodalumab was shown to be beneficial and was subsequently approved for this use in the United States in 2017. Brodalumab was the third monoclonal antibody inhibitor of the IL-17A pathway approved for use in psoriasis, the others having anti-IL-17A activity (secukinumab in 2014 and ixekizumab in 2016). Brodalumab is available as a solution in single dose syringes of 210 mg [in 1.5 mL] under the brand name Siliq. The typical dose is 210 mg by subcutaneous injection at weeks 0, 1 and 2 followed by every 2 weeks. Side effects are not common, but can include arthralgia, myalgia, headache, throat pain, fatigue, diarrhea, nausea, myalgia, neutropenia, tinea infections and injection site reactions. Rare, but potentially severe adverse reactions include severe infections, reactivation of tuberculosis, exacerbation of Crohn disease and immediate hypersensitivity reactions.
Hepatotoxicity
In large premarketing clinical trials of brodalumab in more than 3000 patients with psoriasis, serum enzyme elevations during therapy were no more common than with placebo and there were no instances of clinically apparent liver injury attributed to its use. Since its approval there have been no reports of liver injury attributed to brodalumab therapy and no cases of reactivation of hepatitis B or autoimmune hepatitis, two possible hepatic complications of immunomodulatory monoclonal antibody therapy. However, clinical experience with brodalumab has been limited.
Likelihood score: E (unlikely cause of clinically apparent liver injury).
Mechanism of Injury
The mechanism by which brodalumab might cause liver injury is unknown. Brodalumab is a monoclonal antibody and, like other proteins, is metabolized into amino acids and is unlikely to have intrinsic toxicity. Because of its immunomodulatory activity, brodalumab might induce an autoimmune reaction against hepatocytes, but this has yet to be shown.
Other immunomodulatory biologic agents used to treat severe psoriasis include adalimumab, certolizumab, efalizumab, etanercept, golimumab, infliximab, ixekizumab, secukinumab and ustekinumab.
