Adult Dermatology Safety

Data at week 12


Adverse reactions that occurred in ≥1% of Taltz patients and more frequently than with placebo in plaque psoriasis registration trials1

The most frequent injection site reactions were erythema and pain. Most injection site reactions were mild to moderate in severity and did not lead to discontinuation of Taltz.


Overall, patients with psoriatic arthritis had a safety profile consistent with that of adult patients with plaque psoriasis in UNCOVER-1, -2, and -3 trials, except for frequency of influenza (Taltz 1.3%, placebo 0.4%) and conjunctivitis (Taltz 1.3%, placebo 0%).


In the 2 clinical trials that included Enbrel, an active comparator, the rate of serious adverse events during weeks 0 to 12 was 2% with Taltz and 0.7% with US-approved Enbrel, and the rate of discontinuation from adverse events was 2% with Taltz and 0.7% with US-approved Enbrel.

Data at week 60


Adverse events during weeks 0 to 60 with Taltz vs placebo1

Among those treated with Taltz, the exposure-adjusted incident rates of adverse events from 13 to 60 weeks were lower than the exposure-adjusted incidence rates from 0 to 12 weeks (1.0 vs 2.5 per subject-year of follow-up).

Long-term data

Safety in Taltz clinical trial adult participants studied for up to 6 years2-4

In the adult plaque psoriasis and psoriatic arthritis safety populations, 6989 patients across 15 clinical trials received Taltz, with a total exposure of 16,586 patient-years (PY).

  • In psoriatic arthritis trials, the average duration of exposure was 449 days, with 258 patients having at least 2 years’ exposure
  • In adult plaque psoriasis trials, the average duration of exposure was 946 days, with 2981 patients having at least 3 years’ exposure

Certain adverse events, such as MACE and malignancy, require longer observation periods and larger patient exposure to ascertain risk. Lilly is conducting continued long-term safety studies, including post-marketing studies, to continue to evaluate the safety of Taltz.

The reported safety population includes all dosing arms of the Phase 1-3 psoriasis and Phase 3 psoriatic arthritis clinical trials. Not all patients received the recommended dosing regimen consistent with the FDA-approved label.

Taltz is indicated for adults with active psoriatic arthritis (PsA), for adults with active ankylosing spondylitis (AS), and for adults with active non-radiographic axial spondyloarthritis (nr-axSpA) with objective signs of inflammation. Taltz is also indicated for patients aged 6 years or older with moderate-to-severe plaque psoriasis (PsO) who are candidates for systemic therapy or phototherapy.


Taltz is contraindicated in patients with a previous serious hypersensitivity reaction, such as anaphylaxis, to ixekizumab or to any of the excipients.

Taltz may increase the risk of infection. In clinical trials of adult patients with plaque psoriasis, the Taltz group had a higher rate of infections than the placebo group (27% vs 23%). A similar increase in risk of infection was seen in placebo-controlled trials of adult patients with psoriatic arthritis, ankylosing spondylitis, non-radiographic axial spondyloarthritis, and pediatric patients with plaque psoriasis. Serious infections have occurred. Instruct patients to seek medical advice if signs or symptoms of clinically important chronic or acute infection occur. If a serious infection develops, discontinue Taltz until the infection resolves.

Pre-Treatment Evaluation for Tuberculosis
Evaluate patients for tuberculosis (TB) infection prior to initiating treatment with Taltz. Do not administer to patients with active TB infection. Initiate treatment of latent TB prior to administering Taltz. Closely monitor patients receiving Taltz for signs and symptoms of active TB during and after treatment.

Serious hypersensitivity reactions, including angioedema and urticaria (each ≤0.1%), occurred in the Taltz group in clinical trials. Anaphylaxis, including cases leading to hospitalization, has been reported in post-marketing use with Taltz. If a serious hypersensitivity reaction occurs, discontinue Taltz immediately and initiate appropriate therapy.

Inflammatory Bowel Disease
Patients treated with Taltz may be at an increased risk of inflammatory bowel disease. In clinical trials, Crohn’s disease and ulcerative colitis, including exacerbations, occurred at a greater frequency in the Taltz group than the placebo group. During Taltz treatment, monitor patients for onset or exacerbations of inflammatory bowel disease and if IBD occurs, discontinue Taltz and initiate appropriate medical management.

Prior to initiating therapy with Taltz, consider completion of all age-appropriate immunizations according to current immunization guidelines. Avoid use of live vaccines in patients treated with Taltz.

Most common adverse reactions (≥1%) associated with Taltz treatment are injection site reactions, upper respiratory tract infections, nausea, and tinea infections. Overall, the safety profiles observed in adult patients with psoriatic arthritis, ankylosing spondylitis, non-radiographic axial spondyloarthritis, and pediatric patients with plaque psoriasis were consistent with the safety profile in adult patients with plaque psoriasis, with the exception of influenza and conjunctivitis in psoriatic arthritis and conjunctivitis, influenza, and urticaria in pediatric psoriasis.
