Daclizumab is a humanized monoclonal antibody which binds to the CD25 subunit of the high-affinity interleukin-2 (IL-2) receptor to prevent signaling at the high-affinity IL-2 receptor while allowing increased IL-2 availability for signaling at the intermediate-affinity IL-2 receptor (Gold 2013, Kappos 2015). Because IL-2 has a role in activating and regulating the immune system; CD25 antagonism may result in therapeutic benefit in multiple sclerosis (Gold 2013).

Concerns related to adverse effects:
• Hepatotoxicity: [US Boxed Warning]: Daclizumab may cause severe hepatic injury, including hepatic failure and autoimmune hepatitis; may be life-threatening or fatal. Hepatotoxicity, including autoimmune hepatitis, may occur at any time during daclizumab treatment; cases have been reported up to 4 months after the last dose. Daclizumab is contraindicated in patients with preexisting hepatic disease or hepatic impairment. Obtain serum transaminases (ALT and AST) and total bilirubin levels prior to treatment initiation, monthly before each dose, and monthly for 6 months after the last daclizumab dose. If transaminases or total bilirubin are elevated, treatment interruption or discontinuation may be required. Some patients required systemic corticosteroids or other immunosuppressant treatment for autoimmune hepatitis and continued this treatment after the last daclizumab dose. ALT or AST elevations (including rare elevations >20 times ULN) and bilirubin elevations have occurred during treatment and up to 4 months following the last dose. Monitor for clinical signs/symptoms of hepatic dysfunction (unexplained nausea, vomiting, abdominal pain, anorexia, fatigue, jaundice, and/or dark urine); if reported, promptly obtain serum transaminases and total bilirubin; may require treatment interruption or discontinuation. Prolonged transaminase elevations should be evaluated for alternate causes, including infection. If autoimmune hepatitis is suspected, promptly discontinue daclizumab; may require systemic corticosteroids and other immunosuppressant therapy. Long-term immunosuppression may be necessary. The use of other medications (including OTC medications) associated with hepatotoxicity should be used with caution in combination with daclizumab; carefully consider the need for herbal medicine and dietary supplements which may cause hepatotoxicity.
• Hypersensitivity: Daclizumab may cause anaphylaxis, angioedema, and urticaria after the first dose or at any time during treatment. If anaphylaxis or other allergic reaction occurs, discontinue daclizumab and do not re-initiate.
• Immune-mediated disorders: [US Boxed Warning]: In addition to autoimmune hepatitis, other immune-mediated disorders such as skin reactions, lymphadenopathy, and noninfectious colitis, may occur with daclizumab. Serious immune-mediated conditions were observed in patients who received daclizumab. If a serious immune-mediated disorder develops, consider stopping daclizumab and refer to a specialist for a comprehensive diagnostic evaluation and appropriate management. Some patients required systemic corticosteroids or other immunosuppressant treatment for immune-mediated disorders and continued this treatment after the last daclizumab dose. Concurrent or sequential immune-mediated disorders have been reported during daclizumab treatment. Immune-mediated disorders have resulted in invasive diagnostic procedures, hospitalization, and/or prolonged systemic corticosteroids or other immunosuppressant therapy; some events had not resolved following daclizumab discontinuation and follow-up. Immune- mediated disorders have involved a single organ, or systemic multi-organ reactions. Monitor closely for immune-mediated disorders. Suspected immune-mediated disorders should be adequately evaluated to confirm etiology or to exclude other causes. For serious immune-mediated disorders, consider discontinuing treatment and referring to appropriate specialist for further evaluation and management. Some immune-mediated disorders have required several months for resolution.
• Dermatologic toxicity: Immune-mediated skin reactions, including rash, dermatitis, eczema, and psoriatic conditions, have occurred with daclizumab; may occur at any time during therapy. Photosensitivity has also been reported. Daclizumab may exacerbate eczema or psoriasis in patients with a history of those conditions. Dermatologic toxicity may be managed with topical or systemic corticosteroids, or immunosuppressant therapy (eg, tacrolimus). Some skin reactions have required discontinuation. Rash typically resolved at ~3 months, although some rashes remained unresolved at the final clinical evaluation. Infectious complications due to serious cutaneous reaction has been reported, including a rare fatality. Serious diffuse or inflammatory rashes should be evaluated by a dermatologist prior to the next dose; discontinuation may be appropriate.
• Gastrointestinal toxicity: Serious non-infectious colitis was reported in patients receiving daclizumab. If symptoms of colitis (abdominal pain, fever, prolonged diarrhea) occur, consider referring to a gastroenterologist.
• Lymphadenopathy: An increased incidence of lymphadenopathy was reported in patients who received daclizumab. The onset of lymphadenopathy may occur throughout the daclizumab treatment period. Serious events related to lymphadenopathy/lymphadenitis included infections, salivary neoplasm (benign), skin reactions, thrombocytopenia, and interstitial lung changes. Most cases resolved within 3 months, either with treatment continuing or discontinued. If lymph node biopsy is considered, the patient should undergo a full diagnostic exam by a specialist.
• Infection: Daclizumab increases the risk for infections (some serious). Upper respiratory tract infections, urinary tract infections and viral infections were the most common infections. Avoid initiating daclizumab in patients with severe active infection. If serious infection develops while on therapy, consider withholding daclizumab until infection resolves. Screen for hepatitis B and C prior to treatment initiation.
• Neuropsychiatric events: Depression-related events occurred more frequently in patients receiving daclizumab than in patients who received placebo or comparator drug. Some events were serious, including suicidal ideation or attempt. Use daclizumab with caution in patients with prior or current depressive disorders. Patients or caregivers should immediately report symptoms of new or worsening depression or suicidal ideation. Consider discontinuing daclizumab if severe depression or suicidal ideation develops.
• Tuberculosis: In countries where tuberculosis is endemic, cases of tuberculosis occurred in patients receiving daclizumab. Evaluate patients at high risk for tuberculosis infection prior to treatment initiation. If a test is positive, treat tuberculosis (with standard medical therapy) prior to daclizumab treatment. Avoid initiating daclizumab in patients with tuberculosis.
Disease related concerns:
• Hepatic disease: Patients with ALT or AST >2 times ULN were excluded from clinical studies. Patients with signs/symptoms of hepatic impairment may be at increased risk for hepatotoxicity. Use is contraindicated in patients with preexisting hepatic disease, hepatic impairment, or history of autoimmune hepatitis (or other autoimmune condition involving the liver).
Concurrent drug therapy issues:
• Drug-drug interactions: Potentially significant interactions may exist, requiring dose or frequency adjustment, additional monitoring, and/or selection of alternative therapy. Consult drug interactions database for more detailed information.
• Pediatrics: Due to the risk of hepatic injury and immune-mediated disorders, the use of daclizumab is not recommended in patients <17 years of age.
Dosage form specific issues:
• Polysorbate 80: Some dosage forms may contain polysorbate 80 (also known as Tweens). Hypersensitivity reactions, usually a delayed reaction, have been reported following exposure to pharmaceutical products containing polysorbate 80 in certain individuals (Isaksson 2002, Lucente 2000, Shelley 1995). Thrombocytopenia, ascites, pulmonary deterioration, and renal and hepatic failure have been reported in premature neonates after receiving parenteral products containing polysorbate 80 (Alade 1986, CDC 1984). See manufacturer’s labeling.
• Immunizations: Immunization with live vaccines is not recommended during treatment and for up to 4 months after discontinuation. Consider necessary immunization prior to initiation of daclizumab treatment.
• Immunogenicity: Anti-daclizumab antibodies and neutralizing antibodies may develop, usually during the first year of treatment, with the frequency declining with continued treatment. Anti-daclizumab antibodies were transient in some patients and persistent in others. Daclizumab clearance was increased in patients who developed neutralizing antibodies. Anti-daclizumab antibody and neutralizing antibody development did not correlate to clinical response, adverse reactions, or pharmacodynamics.
• REMS program: [US Boxed Warning]: Due to the risks of hepatotoxicity (including autoimmune hepatitis) and other immune-mediated disorders, daclizumab is only available through a restricted program under a Risk Evaluation and Mitigation Strategy (REMS) called the ZINBRYTA REMS Program. Prescribers and pharmacies must be certified with the program and patients must be enrolled in the program and comply with ongoing monitoring requirements. Further information is available at 1-800-456-2255.
ALT, AST, and total bilirubin (prior to treatment, then monthly during treatment [prior to the next dose] and for 6 months after the last dose). Screen patients for hepatitis B and C (prior to treatment initiation). Evaluate for tuberculosis (in patients at high risk) prior to treatment. Evaluate immunization status prior to treatment. Monitor for signs/symptoms of colitis, depression, dermatologic toxicity, hepatic dysfunction, hypersensitivity, immune-mediated disorders, and infection.
Adverse events were observed in animal reproduction studies. Daclizumab is a monoclonal antibody; monoclonal antibodies are known to cross the placenta, with increasing amounts during the second and third trimesters. Use of similar agents is not recommended for the treatment of multiple sclerosis in pregnant women (Coyle 2016, Pozzilli 2015).
• Discuss specific use of drug and side effects with patient as it relates to treatment. (HCAHPS: During this hospital stay, were you given any medicine that you had not taken before? Before giving you any new medicine, how often did hospital staff tell you what the medicine was for? How often did hospital staff describe possible side effects in a way you could understand?)
• Patient may experience pharyngitis, rhinitis, signs of common cold, or flu-like symptoms. Have patient report immediately to prescriber signs of liver problems (dark urine, fatigue, lack of appetite, nausea, abdominal pain, light-colored stools, vomiting, or jaundice), skin reaction, skin irritation, swollen glands, bloody stools, severe diarrhea, abdominal pain, signs of infection, or signs of depression (suicidal ideation, anxiety, emotional instability, or confusion) (HCAHPS).
• Educate patient about signs of a significant reaction (eg, wheezing; chest tightness; fever; itching; bad cough; blue skin color; seizures; or swelling of face, lips, tongue, or throat). Note: This is not a comprehensive list of all side effects. Patient should consult prescriber for additional questions.
