Ixekizumab Label Information Related to Infections

Ixekizumab is contraindicated in patients with clinically important active infections (e.g. active tuberculosis).1

Treatment with ixekizumab is associated with an increased rate of infections such as upper respiratory tract infection, oral candidiasis, conjunctivitis, and tinea infections.1

Ixekizumab should be used with caution in patients with clinically important chronic infection or a history of recurrent infection. Patients should be instructed to seek medical advice if signs or symptoms suggestive of an infection occur. If an infection develops, monitor carefully and discontinue ixekizumab if the patient is not responding to standard therapy or the infection becomes serious. Ixekizumab should not be resumed until the infection resolves.1

Information from Clinical Trials

Clinical Trial Exclusion Criteria

The use of ixekizumab in patients with HCV has not been studied.

In the pivotal phase 3 clinical trials for PsO, PsA, and axSpA (including AS/r-axSpA and nr-axSpA), patients who had evidence of or tested positive for HCV were excluded.2-7

A positive test for HCV was defined as

  • positive for hepatitis C antibody, and
  • positive via a confirmatory test for HCV (for example, HCV polymerase chain reaction).2-7

Treatment-Emergent Adverse Events


Among all ixekizumab exposures in PsO (N=6645; 17,902 PYs) as of March 2020, there was 1 (0.0%) reported case of hepatitis C and 1 (0.0%) reported case of acute hepatitis C.8

Psoriatic Arthritis

Among all ixekizumab exposures in PsA (data from SPIRIT-P1, -P2, -P3, and SPIRIT-H2H; N=1401; 2247.7 PYs) as of March 2020, there were no cases of hepatitis C reported.8

Axial Spondyloarthritis

Among all ixekizumab exposures in axSpA trials (including AS/r-axSpA and nr-axSpA; N=932; 1792.2 PYs), as of March 2020, there were no cases of hepatitis C reported.8
