Introduction
Reslizumab is a humanized monoclonal antibody to interleukin-5 (IL-5) which leads to a decrease in production and maturation of eosinophils and is used therapeutically to reduce allergic symptoms of asthma in patients with an eosinophilic phenotype. Reslizumab has not been associated with serum enzyme elevations during therapy or to instances of clinically apparent drug induced liver injury.
Background
Reslizumab (res liz' ue mab) is a recombinant, humanized IgG4 monoclonal antibody to IL-5 which binds to the circulating cytokine and blocks its ability to cause maturation and proliferation of eosinophils. IL-5 is a cytokine growth and stimulating factor which has a selective role in recruiting eosinophils from the bone marrow and promoting their differentiation, activation and survival. Reslizumab lowers eosinophil counts in patients with hypereosinophilia as well as in normal, healthy controls. Therapy with reslizumab has been shown to reduce the requirement for inhaled corticosteroids and lower the frequency of exacerbations of eosinophilic asthma and other conditions associated with severe hypereosinophilia. Reslizumab was approved for use in the United States in 2016 for therapy of adult patients with severe eosinophilic asthma resistant to standard therapy with inhaled corticosteroids. Reslizumab is available in solution in single use vials of 100 mg in 10 mL (10 mg/mL) under the brand name Cinqair. The recommended dose is 3 mg/kg given intravenously over 20 to 30 minutes every 4 weeks. Side effects are not common, but can include injection site reactions, muscle pain, oropharyngeal pain, back pain, fatigue, nausea and creatine kinase (CK) elevations. Reslizumab can also cause severe hypersensitivity reactions including anaphylaxis, for which reason it should be administered in a health care setting and patients observed during and for a period of time after the infusion.
Hepatotoxicity
In large clinical trials, reslizumab was not associated with changes in serum aminotransferase levels during therapy, and rates of most adverse reactions were similar in patients who received placebo injections or standard care. There have been no published reports of clinically apparent acute liver injury attributed to reslizumab therapy. Thus, liver injury from reslizumab must be rare, if it occurs at all.
Likelihood score: E (unlikely cause of clinically apparent liver injury).
Mechanism of Injury
Reslizumab is a humanized monoclonal antibody and is unlikely to be inherently hepatotoxic. Recombinant proteins are usually metabolized in the cells on which they act but are also metabolized in the liver, largely to small peptides and amino acids which may be reused to synthesize proteins and are unlikely to be toxic or immunogenic. Reslizumab lowers serum eosinophil counts, which seems to have no adverse effects on the liver and does not result in significant immunosuppression.
