Taltz® ▼ (ixekizumab): Switching from Ixekizumab to a Different Biologic Treatment

Switching from ixekizumab to a different biologic has not been studied by Eli Lilly and Company.

Clinical Trial Data

Switching from ixekizumab to a different biologic, including to a TNF inhibitor, has not been studied by Lilly in clinical trials.

Treatment Guidelines on Biologic Switching

Specific recommendations on switching from ixekizumab to another biologic are not available. 

  • The Joint American Academy of Dermatology and National Psoriasis Foundation 2019 guidelines on the treatment and management of psoriasis with biologics states no evidence-based studies have been conducted to determine the appropriate duration of time between discontinuation of the previous medication and initiation of a biologic. The guidelines suggest assessments should be done on a case-by-case basis considering many factors including

    • treatment being discontinued

    • disease severity

    • response to previous treatment, and

    • on expert opinion (some experts will begin administration of the new biologic as soon as it is available; whereas, others may wait 3 to 4 half-lives of the previous therapy before beginning the new biologic).1

  • The British Association of Dermatologists 2017 psoriasis guidelines for biologic therapies include to consider using a washout period of 1 month or the length of a treatment cycle (whichever is longer) when transitioning between biologic therapies.2

  • The Transitioning Therapies programme consensus published in 2014 recommends when switching from one biologic therapy to another to include the use of a washout period if the switch is made due to an AE and do not include a washout period if the switch is made due to a lack of efficacy. Initiation of the second biologic therapy occurs with the usual induction and maintenance dosages.3
