DACLIZUMAB

OVERVIEW
Daclizumab

 

Introduction

Daclizumab is a humanized monoclonal antibody to CD25, the alpha subunit of the IL2 receptor on T lymphocytes, which has been used to treat and prevent acute cellular rejection after solid organ transplantation.  Daclizumab has been linked to mild and transient serum enzyme elevations during therapy, but has not been linked to cases of clinically apparent liver injury and, while it is a potent immunosuppressive agent, daclizumab has not been linked to cases of reactivation of hepatitis B.

 

Background

Daclizumab (da kliz’ ue mab) is a humanized monoclonal immunoglobulin G1 antibody to the alpha subunit of the IL2 receptor (CD25).  The IL2 receptor is found on T cells and its engagement results in activation and proliferation of T cells and generation of proinflammatory cytokines.  Inhibition of the receptor by antibody results in prevention of activation and inhibition of T cell responses.  Daclizumab has been shown to be effective in reducing in incidence of acute rejection after renal, liver, heart and lung transplantation.  Daclizumab was approved for use in preventing acute rejection after renal transplantation in 1997 and has been used largely as a part of induction regimens at and around the time of transplant.  Daclizumab was available in liquid solution in single use vials of 25 mg (5 mg/mL) under the brand name Zenapax.  A typical regimen was 25 mg intravenously given at the time of transplant and then every 1-2 weeks for a total of 5 doses.  Several other biologic products are available and used in solid organ transplantation including monoclonal antibodies basiliximab (anti-CD25) and alemtuzumab (anti-CD24) and immune globulins such as anti-thymocyte globulin.  Daclizumab was withdrawn by the sponsor in 2007 because of market factors rather than toxicity or lack of efficacy.  Daclizumab has been used experimentally and off label in the therapy of serious autoimmune conditions, such as chronic uveitis and multiple sclerosis, but it is not formally approved in those diseases.  Side effects of daclizumab when used as induction therapy for solid organ transplantation are uncommon, but can include infusion reactions, chills, fever, skin rash, fatigue, leukopenia and infections.

 

Hepatotoxicity

When given as a part of induction therapy for solid organ transplantation, daclizumab has not been linked to instances of serum enzyme elevations or clinically apparent liver injury.  While adverse events at the time of organ transplantation are common, they were not found to be more frequent in patients receiving induction therapy with daclizumab than in those given conventional immunosuppressive regimens.  In studies of long term daclizumab therapy (as in autoimmune conditions), transient and asymptomatic elevations of serum aminotransferase levels have been reported in up to one third of patients, but these elevations were rarely severe (~2% were above 5 times ULN) and instances of clinically apparent or symptomatic acute liver injury have not been reported during daclizumab therapy.

Daclizumab is a potent immunosuppressive agent and may be capable of causing reactivation of chronic hepatitis B.  However, its use in prevention of organ rejection has not been linked to cases of reactivation, perhaps because patients at risk are routinely given prophylaxis and the role of daclizumab versus other rejection medications (cyclosporine, tacrolimus, corticosteroids) is not clear.  In trials of daclizumab in multiple sclerosis and uveitis, cases of reactivation of hepatitis B or worsening of hepatitis C were not reported, but patients with coexisting hepatitis B or C are often excluded from early phase trials of immunosuppressive agents.
