Eli Lilly and Company (NYSE: LLY) announced today that patients with moderate-to-severe plaque psoriasis treated with Taltz® (ixekizumab) demonstrated superior efficacy at 24 weeks compared to patients treated with Stelara®* (ustekinumab). Detailed results from the IXORA-S study were presented during the American Academy of Dermatology (AAD) Annual Meeting taking place March 3-7 in Orlando, Fla.
At 24 weeks, patients treated with Taltz achieved significantly higher response rates compared to patients treated with Stelara, including 83 percent of patients who achieved Psoriasis Area Severity Index (PASI) 90—the study's primary endpoint—compared to 59 percent of patients who achieved PASI 90 after treatment with Stelara.
"For many years, achieving PASI 75 - or 75 percent improvement in skin plaques - has been the standard treatment goal for moderate-to-severe plaque psoriasis," said Kristian Reich, M.D., Ph.D., lead author and professor, Georg-August-University Göttingen and Dermatologikum Hamburg, Hamburg, Germany. "With the introduction of treatments like Taltz, dermatologists can offer treatment options that allow more patients to achieve PASI 90 or PASI 100. The data of the IXORA-S study is significant, as it demonstrates both high levels of skin improvement for patients treated with Taltz, consistent with pivotal Phase 3 trials, as well as higher response rates over Stelara, which is one of the most frequently used biologics in the treatment of moderate-to-severe plaque psoriasis."
In the IXORA-S study, patients were randomized to receive either Stelara (45 mg or 90 mg weight-based dosing per label) or Taltz (80 mg every two weeks for 12 weeks followed by 80 mg every four weeks), following a 160-mg starting dose, for a total of 52 weeks.
This study also evaluated PASI 75, PASI 100 and static Physician's Global Assessment score (sPGA) 0 or 1 with at least a two-point improvement from baseline. PASI measures the extent and severity of psoriasis by assessing average redness, thickness and scaliness of skin lesions (each graded on a zero to four scale), weighted by the body surface area of involved skin.1 The sPGA is the physician's assessment of severity of a patient's psoriasis lesions overall at a specific point in time and is a required measure the FDA uses to evaluate effectiveness.1
At 24 weeks, patients treated with Taltz achieved significantly higher response rates compared to patients treated with Stelara, as demonstrated by the following:
- 91.2 percent of patients treated with Taltz achieved PASI 75 compared to 81.9 percent of patients treated with Stelara (p=0.015);
- 83.1 percent of patients treated with Taltz achieved PASI 90 compared to 59.0 percent of patients treated with Stelara (p < 0.001);
- 49.3 percent of patients treated with Taltz achieved PASI 100 compared to 23.5 percent of patients treated with Stelara (p=0.001).
Additionally, 86.6 percent of patients treated with Taltz achieved sPGA 0 or 1 compared to 69.3 percent of patients treated with Stelara after 24 weeks (p < 0.001).
The majority of treatment-emergent adverse events were mild or moderate. There were no statistically significant differences between treatment groups in overall treatment-emergent adverse events. The safety profile for Taltz was consistent with previous clinical trials.
"The approval of Taltz in the U.S., Canada and Europe nearly one year ago introduced a treatment option that could help patients with moderate-to-severe plaque psoriasis achieve virtually clear or completely clear skin," said Dr. Lotus Mallbris, global brand development leader, Taltz, Eli Lilly and Company. "We are thrilled with the opportunity to share this new data with dermatologists at AAD, as it reinforces the clinical benefits of Taltz for patients with moderate-to-severe plaque psoriasis."
Results from Phase 3 trials evaluating Taltz for the treatment of active psoriatic arthritis are expected to be presented later this year. Taltz is also in Phase 3 trials for the treatment of axial spondyloarthritis.
Indications and Usage
Taltz® (ixekizumab) is indicated for the treatment of adults with moderate-to-severe plaque psoriasis who are candidates for systemic therapy or phototherapy.
IMPORTANT SAFETY INFORMATION
CONTRAINDICATIONS
Taltz is contraindicated in patients with a previous serious hypersensitivity reaction, such as anaphylaxis, to ixekizumab or to any of the excipients.
WARNINGS AND PRECAUTIONS
Infections
Taltz may increase the risk of infection. The Taltz group had a higher rate of infections than the placebo group (27% vs. 23%). 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. Patients receiving Taltz should be monitored closely for signs and symptoms of active TB during and after treatment.
Hypersensitivity
Serious hypersensitivity reactions, including anaphylaxis, angioedema and urticaria, have been reported with Taltz. If a serious hypersensitivity reaction occurs, discontinue Taltz immediately and initiate appropriate therapy.
Inflammatory Bowel Disease
Crohn's disease and ulcerative colitis, including exacerbations, occurred at a greater frequency in the Taltz group (Crohn's disease 0.1%, ulcerative colitis 0.2%) than in the placebo group (0%) during clinical trials. During Taltz treatment, monitor patients for onset or exacerbations of inflammatory bowel disease.
Immunizations
Prior to initiating therapy with Taltz, consider completion of all age-appropriate immunizations according to current immunization guidelines. Live vaccines should not be given with Taltz.
ADVERSE REACTIONS
Most common adverse reactions ( > 1%) associated with Taltz treatment are injection site reactions, upper respiratory tract infections, nausea, and tinea infections.

About Taltz® (ixekizumab)
Taltz® (ixekizumab) is an IgG4 monoclonal antibody that selectively binds with interleukin 17A (IL-17A) cytokine and inhibits its interaction with the IL-17 receptor. IL-17A is a naturally occurring cytokine that is involved in normal inflammatory and immune responses. Taltz inhibits the release of pro-inflammatory cytokines and chemokines.
About Moderate-to-Severe Plaque Psoriasis
Psoriasis is a chronic, immune disease that affects the skin.2 It occurs when the immune system sends out faulty signals that speed up the growth cycle of skin cells. Psoriasis affects approximately 125 million people worldwide, approximately 20 percent of whom have moderate-to-severe plaque psoriasis.2,3 Psoriasis can occur on any part of the body and is associated with other serious health conditions, such as diabetes and heart disease.2 The most common form of psoriasis, plaque psoriasis, appears as raised, red patches covered with a silvery white buildup of dead skin cells.2
