Taltz® (ixekizumab): How often do injection site reactions occur with Taltz treatment?

Injection site reactions were more frequently reported with ixekizumab treatment compared with placebo in clinical trials.

 Ixekizumab Label Information Related to Injection Site Reactions

Injection site reactions were very commonly (≥ 1/10) reported adverse drug reactions with ixekizumab treatment.1

The most frequent injection site reactions observed were erythema and pain. These reactions were predominantly mild to moderate in severity and did not lead to discontinuation of ixekizumab.1

In the adult plaque psoriasis studies, injection site reactions were more common in subjects with a body weight <60 kg compared with the group with a body weight ≥60kg (25% vs. 14% for the combined Q2W and Q4W groups).1

In the psoriatic arthritis studies, injection site reactions were more common in subjects with a body weight <100 kg compared with the group with a body weight ≥100 kg (24% vs. 13% for the combined Q2W and Q4W groups).1

In the axial spondyloarthritis studies, injection site reactions were similar in subjects with a body weight <100 kg compared with the group with a body weight ≥100 kg (14% vs. 9% for the combined Q2W and Q4W groups).1

The increased frequency of injection site reactions in the combined Q2W and Q4W groups did not result in an increase in discontinuations in either the plaque psoriasis, or the psoriatic arthritis or the axial spondyloarthritis studies.1

Note that multiple, different dosing regimens, including unapproved doses, are included in this response. Please refer to Taltz summary of product characteristics for full prescribing information.

Injection Site Reactions in Psoriasis Clinical Trials

Integrated Data

Injection site reactions were reported as an adverse event in 15.1% (1004/6645) [IR=5.6 per 100 PYs of exposure] of patients exposed to ixekizumab across 16 adult and pediatric psoriasis trials as of March 19, 2020.2 Of these, the most commonly reported types of ISRs are shown in Table 1.

Abbreviations: IR = incidence rate per 100 patient-years of exposure; PY = patient-year.

Data From 12-Week, Double Blind, Placebo-Controlled Induction Period

Patients who reported an ISR of any type during psoriasis trials were given a follow-up form in order to collect additional information. Follow-up of patients who spontaneously reported an ISR of any type showed 51% reported pain, the majority (>90%) of which were categorized by the patient as mild-to-moderate in severity.3

  • The majority of reported ISRs in UNCOVER-1, -2, and -3 occurred following the initial 160-mg starting dose.3 Median time to onset was 7 days for the first 160-mg dose. For those with multiple ISRs reported, subsequent doses had earlier median time to onset of 1.5 days for week 2 and 4 injections.4

  • The median duration of ISRs was 2 days.5

  • Generally, injection site pain was typically reported to occur during injection and erythema onset was delayed.4

  • Timing of ISRs varied depending on treatment group (ixekizumab 80 mg Q2W and Q4W dosing groups, etanercept, or placebo) and symptom reported.6

Injection Site Reactions in Psoriatic Arthritis Clinical Trials

Integrated Data

Injection site reactions were reported as an adverse event in 18.6% (260/1401) [IR=11.6 per 100 PYs of exposure] of patients exposed to ixekizumab across 4 psoriatic arthritis trials (SPIRIT-P1, SPIRIT-P2, SPIRIT-P3, and SPIRIT-H2H) as of March 19, 2020.3 Of these, the most commonly reported types of ISRs are shown in Table 2.

Data From 24-Week Double-Blind Treatment Periods of SPIRIT-P1 and SPIRIT-P2 trials

Most ISRs (>95%) were mild-to-moderate in severity.3,7 Of patients who reported an ISR, 1.1% discontinued ixekizumab due to ISR.7,8

Patients who reported an ISR of any type during trials were given a follow-up form in order to collect additional information. Follow-up of patients who spontaneously reported an ISR of any type treated with ixekizumab 80 mg Q4W showed that 32.5% reported pain, the majority (>90%) of which were categorized by the patient as mild-to-moderate.3

Injection Site Reactions in Axial Spondyloarthritis Clinical Trials

Integrated Data

Injection site reactions were reported as an adverse event in 16.6% (155/932) [IR=8.4 per 100 PYs of exposure] of patients across 4 axSpA trials (including AS/r-axSpA and nr-axSpA trials) as of March 19, 2020.9 Of these, the most commonly reported types of ISRs are shown in Table 3.

Most ISRs (>95%) were mild-to-moderate in severity.3,10,11 Of patients who reported an ISR, 1.1% discontinued ixekizumab due to ISR.10,11

  • The frequency and exposure-adjusted IR was greater during the first 2 weeks of treatment compared with later 2-week intervals.3

  • The median duration of ISRs was 2.8 days.3

Data From 52-Week Double-Blind, Placebo-Controlled Treatment Periods of COAST-X nr-axSpA Trial

Injection site reactions were reported in 21.7% (43/198) of patients with nr-axSpA treated with ixekizumab during the 52-week double-blind treatment period of COAST-X.12

Most ISRs (>95%) were mild-to-moderate in severity. Of patients who reported ISR, 1.6% discontinued due to ISR.12
