Background Information

This response includes reports of anterior uveitis (MedDRA-preferred term "iridocyclitis") in psoriasis, psoriatic arthritis, and axSpA (including AS/r-axSpA and nr-axSpA) clinical trials. 

The most common extra-muscular-skeletal feature of spondyloarthritis is uveitis. Up to 50% of patients with AS/r-axSpA will experience uveitis, and the most common type is anterior uveitis. The occurrence of uveitis has been associated with HLA-B27 status and duration of the spondyloarthropathy.1

Uveitis as Adverse Drug Reaction

Uveitis is not listed as adverse drug reaction in the Taltz summary of product characteristics. 2

Exclusion Criteria in Ixekizumab Clinical Trials Related to Uveitis

Plaque Psoriasis Trials

No specific exclusion criteria for uveitis were included in the pivotal phase 3 plaque psoriasis clinical trials.3

Psoriatic Arthritis Trials

Patients with active vasculitis or uveitis were excluded from participation in the phase 3 psoriatic arthritis clinical trials.4,5

Ankylosing Spondylitis/Radiographic Axial Spondyloarthritis Trials

Patients were excluded from COAST-V and COAST-W if they had evidence of active anterior uveitis (an acute episode) within the last 4 weeks prior to baseline randomization. These patients were allowed to be rescreened only 1 time ≥4 weeks after resolution of acute symptoms. Other patients with a previous history of uveitis were allowed to be enrolled in the study.6,7

Non-radiographic Axial Spondyloarthritis

Patients were excluded from COAST-X if they had evidence of active anterior uveitis (an acute episode) within the last 42 days prior to baseline randomization. These patients were allowed to be rescreened only 1 time ≥4 weeks after resolution of acute symptoms. Other patients with a previous history of uveitis were allowed to be enrolled in the study.8

History of Anterior Uveitis and Treatment-Emergent Adverse Events of Anterior Uveitis in Ixekizumab Clinical Trials

Appendix: Brief Clinical Trial Descriptions

Plaque Psoriasis Trials

  • UNCOVER-1, -2, and -3 (N=3866) phase 3 trials in moderate-to-severe plaque psoriasis were integrated to evaluate the safety of ixekizumab in comparison to placebo up to 12 weeks after treatment initiation.
  • The phase 3 trials examined the efficacy and safety of ixekizumab compared with placebo and etanercept (UNCOVER-2 and -3) during induction treatment and vs placebo in maintenance (UNCOVER-1 and -2).3
Induction (UNCOVER-1, -2, -3) and Maintenance (UNCOVER-1, -2) Dosing Period Study Designs3

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.

Notes:
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.

Nonresponders 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.

Nonresponders 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.

 Some dosing schedules shown in Induction (UNCOVER-1, -2, -3) and Maintenance (UNCOVER-1, -2) Dosing Period Study Designs are not consistent with the approved dosing schedule for plaque psoriasis in the Taltz summary of product characteristics. Please refer to the Taltz summary of product characteristics for approved dosing.2

Psoriatic Arthritis Trials

  • SPIRIT-P1 (N=417) is a phase 3, 24-week double-blind, placebo-controlled trial with an active reference arm in patients with active PsA who are naïve to bDMARDs with an extension period of up to 3 years.12
  • SPIRIT-P2 (N=363) is a phase 3, 24-week double-blind, placebo-controlled trial in patients with active PsA and an inadequate response or intolerance to TNF inhibitor, with an extension period of up to 3 years.4
  • SPIRIT-P3 (N=570) consists of a 36-week open-label period followed by a randomized double-blind withdrawal period from week 36 to week 104. This trial is being conducted in patients naïve to bDMARDs.13

Axial Spondyloarthritis Trials

  • COAST-V (N=341) is a phase 3, 16-week double-blind, placebo-controlled trial with an active reference arm and a dose double-blind extension period to 52 weeks in patients with active AS/r-axSpA who are naive to bDMARDs.7
  • COAST-W (N=316) is a phase 3, 16-week double-blind, placebo-controlled trial with a dose double-blind extension period to 52 weeks in patients with active AS/r-axSpA and an inadequate response or intolerance to 1 or 2 TNF inhibitors.6
  • COAST-X (N=303) is a phase 3, 52-week double-blind, placebo-controlled trial in patients with nr-axSpA who are naive to bDMARDs.8
  • COAST-Y (N=750) is a phase 3, 104-week, long-term extension trial including a double-blind, placebo-controlled 40-week randomized withdrawal-retreatment period in patients with axial spondyloarthritis who have completed the final study visit in COAST-V, COAST-W, or COAST-X.14
