TALTZ® (ixekizumab):Dose when Re-starting Treatment for Plaque Psoriasis Following Prior Discontinuation

Data are available from Phase 3 clinical trials on re-starting Taltz (ixekizumab) following treatment discontinuation and subsequent relapse.


Detailed Information

  • Ixekizumab prescribing information does not include specific recommendations for reinitiating the dose when restarting ixekizumab following prior discontinuation or prolonged interruption of treatment.1
  • For the analyses summarized below, response (both initial and regained response) was defined as a sPGA score of 0 (clear skin) or 1 (minimal) and relapse was defined as a sPGA score of >3.2
  • In 2 phase 3 clinical trials (UNCOVER-1 and -2), patients who were originally randomized to ixekizumab and who responded to treatment at week 12 were re-randomized to an additional 48 weeks of ixekizumab 80 mg Q4W, ixekizumab 80 mg Q12W, or placebo.2
  • Among the patients who relapsed and were retreated, within 12 weeks of restarting treatment with ixekizumab 80 mg Q4W, 66% regained a response of sPGA (0,1).1

Appendix A: Brief Description of the UNCOVER Clinical Trials

Induction (UNCOVER-1, -2, -3) and Maintenance (UNCOVER-1, -2) Dosing Period Study Designs4

Abbreviations: ETN = etanercept; IXE Q2W = ixekizumab 80 mg every 2 weeks; IXE Q4W = ixekizumab 80 mg every 4 weeks; IXE Q12W = ixekizumab 80 mg every 12 weeks; PBO = placebo; R = randomization; sPGA = static Physician Global Assessment.

ETN arm was not included in UNCOVER-1.

Responders (sPGA 0 or 1) to ixekizumab at week 12 were re-randomized to receive IXE Q4W, IXE Q12W, or PBO.

Non-responders to ETN at week 12 in UNCOVER-2 were switched to IXE Q4W (without a 160 mg starting dose) after a 4-week washout period.

Non-responders to PBO at week 12 received a 160 mg starting dose of ixekizumab followed by IXE Q4W.

⁞ (dotted line) = relapse (sPGA≥3).

UNCOVER-3 is not represented in maintenance period design as the extension period consisted of open-label treatment with IXE Q4W.


Q4W = every 4 weeks

Q12W = every 12 weeks

sPGA = static Physician Global Assessment
