Taltz® (ixekizumab): Infektioner i den kliniska prövningen för pediatrisk psoriasis

Ixekizumab Infections-Related Label Information

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

Ixekizumab must not be given to patients with active tuberculosis (TB). Consider anti-TB therapy prior to initiation of ixekizumab in patients with latent TB.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

The safety profile observed in children with plaque psoriasis treated with ixekizumab every 4 weeks is consistent with the safety profile in adult patients with plaque psoriasis with the exception of the frequencies of conjunctivitis, influenza, and urticaria which were common.¹

Further information on this topic is available in section 4.8 of the Taltz Summary of Product Characteristics.¹

Treatment-Emergent Infections in IXORA-PEDS

A summary of treatment-emergent infections in IXORA-PEDS are listed in Table 1.

During the double-blind treatment period

• there were no severe or serious infection-related AEs

• no patients discontinued study drug due to an infection-related AE, and

• there were no opportunistic infections or candida infections.^2,3

In the all ixekizumab exposure population as of the 48-week interim database lock

• 1 patient (0.5%) reported a severe infection (pharyngitis)

• 2 patients (1.0%) reported serious infections (1 each of otitis media acute and tonsillitis)

• no patients discontinued study drug due to an infection-related AE

• there were no opportunistic infections, and

• 1 patient (0.5%) reported a TEAE of fungal infection, which was a mild oral candida infection of 5 days duration.^2,3

Abbreviations: PY = patient-years; Q4W = every 4 weeks.

^a Occurring in ≥3% of ixekizumab-treated patients or adverse event of special interest.

^b All patients exposed to ixekizumab in the induction, maintenance, and extension periods through the 48-week interim database lock (253.9 total PY of exposure), including patients switched to ixekizumab from placebo or etanercept following the double-blind induction treatment period.

^c Pharyngitis.

^d Mild oral candida infection.

Integrated Safety Across All Ixekizumab Psoriasis Clinical Trials

An integrated safety analysis was conducted from all ixekizumab psoriasis exposures (N=6091; PY=17,499.3) across 14 plaque psoriasis clinical trials, including IXORA-PEDS, as of March 2019. The proportion of patients with

• any infection was 65.3% [IR=22.7/100 PYs of exposure]

• serious infections was 3.7% [IR=1.3/100 PYs of exposure], and

• oral candidiasis was 2.3% [IR=0.8/100 PYs of exposure].

The IR of infections did not increase with longer ixekizumab exposure.⁴
