The first IL-17A antagonist now approved for adult patients across the spectrum of axSpA (nr-axSpA, AS)  

Radiographic response

Taltz helped stop the progression of structural joint damage at week 16 vs placebo1-3,7

SPIRIT-P1 BIOLOGIC-NAIVE: ADJUSTED MEAN CHANGE FROM BASELINE IN mTSS, JOINT SPACE NARROWING SCORE, AND BONE EROSION SCORE AT WEEK 16, MMRM

Primary endpoint=ACR20 response at week 24.

Inhibition of progression of structural damage was assessed radiographically and expressed as the mean change in mTSS and its components, the joint space narrowing score and bone erosion score, at week 16 vs baseline. The mTSS score was modified for psoriatic arthritis by addition of hand distal interphalangeal (DIP) joints.

SPIRIT-P2 (TNFi-experienced) did not include an assessment of radiographic progression.

mTSS=modified Total Sharp Score; MMRM=mixed-effect model of repeated measure.

SELECT IMPORTANT SAFETY INFORMATION
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 exacerbation of inflammatory bowel disease and if IBD occurs, discontinue Taltz and initiate appropriate medical management.

89% of Taltz patients had almost no progression of structural joint damage* at week 528,9

SPIRIT-P1 BIOLOGIC-NAIVE: POST HOC ANALYSIS OF OPEN-LABEL EXTENSION PERIOD POPULATION: CHANGE FROM BASELINE IN mTSS IN INDIVIDUAL PATIENTS AT WEEK 52, OBSERVED; 89% of Taltz patients had almost no progression of structural joint damage at week 52

Mean change from baseline in mTSS at week 52 was 0.47 for patients in the extension period on Taltz 80 mg every 4 weeks.

SELECT IMPORTANT SAFETY INFORMATION
IMMUNIZATIONS
Prior to initiating Taltz, consider completion of all ageappropriate immunizations according to current immunization guidelines. Avoid use of live vaccines in patients treated with Taltz.

Indications and Important Safety Information
Indications

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.

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. 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.

Hypersensitivity
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.

Immunizations
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.

ADVERSE REACTIONS
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.

SPIRIT-H2H: Trial design9

Taltz icon

SPIRIT-H2H (N=566) was a phase 4, randomized, open-label, blinded-assessor study evaluating the efficacy and safety of Taltz vs Humira in biologic-naive patients with active psoriatic arthritis and plaque psoriasis BSA ≥3%.

Patients who met the trial design criteria for moderate to severe psoriasis (BSA ≥10%, PASI ≥12, and sPGA ≥3) in addition to psoriatic arthritis followed the psoriasis dosing regimen: Taltz patients (n=49) received an initial dose of 160 mg (two 80 mg injections), followed by 80 mg every 2 weeks through week 12, then 80 mg every 4 weeks thereafter. Humira patients (n=52) received an initial dose of 80 mg, then 40 mg every other week starting 1 week after the initial dose. For Taltz patients with psoriatic arthritis only (n=234), the initial dose (160 mg as 2 injections) was followed by 80 mg every 4 weeks. Humira patients (n=231) received 40 mg every other week and no initial dose.

SPIRIT-H2H: Trial design1

SPIRIT-H2H (N=566) was a phase 4, randomized, open-label, blinded-assessor study evaluating the efficacy and safety of Taltz vs Humira® (adalimumab) in biologic-naive patients with active psoriatic arthritis and plaque psoriasis BSA ≥3%. The primary efficacy endpoint was the proportion of patients simultaneously achieving ACR50 and PASI 100 at week 24. All patients were ≥18 years of age and had ≥3 swollen and ≥3 tender joints with an inadequate response to ≥1 cDMARD. Patients were randomized (1:1) to Taltz or Humira and allowed to continue a stable dose of concomitant cDMARD during the study. For Taltz patients with psoriatic arthritis only (n=234), the initial dose (160 mg as 2 injections) was followed by 80 mg every 4 weeks. Humira patients (n=231) received 40 mg every other week and no initial dose. Patients who met the trial design criteria for moderate to severe psoriasis (BSA ≥10%, PASI ≥12, and sPGA ≥3) in addition to psoriatic arthritis followed the psoriasis dosing regimen: Taltz patients (n=49) received an initial dose of 160 mg (two 80 mg injections), followed by 80 mg every 2 weeks through week 12, then 80 mg every 4 weeks thereafter. Humira patients (n=52) received an initial dose of 80 mg, then 40 mg every other week starting 1 week after the initial dose.

SPIRIT-P1 and -P2 Trial Design1-4

SPIRIT-P1 (N=417) and -P2 (N=363) were phase 3, randomized, double-blind, placebo-controlled trials to evaluate the efficacy and safety of Taltz compared with placebo in patients with active psoriatic arthritis. Patients in SPIRIT-P1 were biologic-naive. Patients in SPIRIT-P2 were tumor necrosis factor inhibitor (TNFi)-experienced, having had an inadequate response and/or intolerance to 1 or 2 prior TNFis. In both trials, the primary efficacy endpoint was the proportion of patients achieving ACR20 response at week 24. All patients were ≥18 years of age and had ≥3 swollen and ≥3 tender joints. Patients were randomized to placebo or Taltz 80 mg every 2 or 4 weeks following a 160 mg starting dose. In SPIRIT-P1, an active reference arm of Humira® (adalimumab) 40 mg every 2 weeks was included. Patients in all study arms were allowed to continue taking stable background medications during the trial. Inadequate responders (as defined by blinded criteria of <20% improvement in tender and in swollen joint counts) at week 16 received rescue therapy and were analyzed as nonresponders after week 16 until the primary endpoint. After receiving rescue therapy, inadequate responders in the placebo and Humira arms were re-randomized to Taltz 80 mg every 2 or 4 weeks. Nonresponder imputation (NRI) methods were used for categorical efficacy analyses during the double-blind treatment period.

Registration Trials

SPIRIT-P1 (N=417) and SPIRIT-P2 (N=363) were phase 3, randomized, double-blind, placebo-controlled trials to evaluate the efficacy and safety of Taltz compared with placebo in patients with active psoriatic arthritis. Patients in SPIRIT-P1 were biologic-naive. Patients in SPIRIT-P2 were tumor necrosis factor inhibitor (TNFi)-experienced, having had an inadequate response and/or intolerance to 1 or 2 prior TNFis. In both trials, the primary efficacy endpoint was the proportion of patients achieving ACR20 response at week 24. All patients were ≥18 years of age and had ≥3 swollen and ≥3 tender joints. Patients were randomized to placebo or Taltz 80 mg every 2 or 4 weeks following a 160 mg starting dose. In SPIRIT-P1, an active reference arm of adalimumab 40 mg every 2 weeks was included. Patients in all study arms were allowed to continue taking stable background medications during the trial. Inadequate responders (as defined by blinded criteria of <20% improvement in tender and in swollen joint counts) at week 16 received rescue therapy and were analyzed as nonresponders after week 16 until the primary endpoint. After receiving rescue therapy, inadequate responders in the placebo and adalimumab arms were re-randomized to Taltz 80 mg every 2 or 4 weeks. Nonresponder imputation (NRI) methods were used for categorical efficacy analyses during the double-blind treatment period.

IXORA-PEDS TRIAL DESIGN

IXORA-PEDS (N=171) is an ongoing, multicenter, randomized, double-blind, placebo-controlled phase 3 study designed to evaluate the efficacy and safety of Taltz in pediatric patients aged 6 to <18 years with moderate to severe plaque psoriasis. All patients have a diagnosis of moderate to severe plaque psoriasis for at least 6 months, with a body surface area (BSA) of ≥10%, a static Physician’s Global Assessment (sPGA) score ≥3, and a Psoriasis Area Severity Index (PASI) score ≥12, and are candidates for systemic therapy or phototherapy. Patients were randomized to receive Taltz every 4 weeks (n=115), with dosing based on body weight, or placebo (n=56). Of patients receiving Taltz, those weighing <25 kg were randomized to Taltz 20 mg every 4 weeks following a 40 mg starting dose, those weighing 25 to 50 kg were randomized to Taltz 40 mg every 4 weeks following an 80 mg starting dose, and those weighing >50 kg were randomized to Taltz 80 mg following a starting dose of 160 mg. Co-primary efficacy endpoints were the percentage of patients achieving PASI 75 and sPGA 0,1 at week 12. Secondary endpoints were the percentage of patients achieving the following measures: PASI 75 at week 4, sPGA 0,1 at week 4, PASI 90 at week 12, PASI 100 at week 12, sPGA 0 at week 12, and Itch Numeric Rating Scale (I-NRS) ≥4-point improvement at week 12. Nonresponder imputation methods (NRI) were used for categorical efficacy analyses.

Following the double-blind treatment period, patients are allowed to transition to an open-label maintenance period (weeks 12-60) and extension period (weeks 60-108) where all patients, regardless of initial treatment, will receive Taltz every 4 weeks through week 108. Patients who were taking placebo were initiated to Taltz with the appropriate weight-based starting dose, followed by the appropriate weight-based Q4W dose.
