Dactylitis

FOR BIOLOGIC-NAIVE PATIENTS WITH PSORIATIC ARTHRITIS

Taltz showed improvement in patients with preexisting dactylitis2,3,10

Rheumatology efficacy spirit p1 dac bar

In SPIRIT-P2 (TNFi-experienced) (Taltz 80 mg every 4 weeks n=28, mean baseline=31.5; placebo n=14, mean baseline=37.3), 75% of Taltz patients had complete resolution of dactylitis at week 24 vs 21% for placebo.

The data presented were from post hoc analyses and were not type-I error-controlled; therefore, treatment differences between Taltz and placebo cannot be regarded as statistically significant.

Mean baseline LDI-B was 73.0 for Taltz and 62.7 for placebo.

Inadequate responders (<20% in tender and in swollen join counts) at week 16 were analyzed as nonresponders after week 16 until the primary endpoint.

SELECT IMPORTANT SAFETY INFORMATION
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 profile observed in patients with psoriatic arthritis was consistent with the safety profile in patients with plaque psoriasis, with the exception of influenza and conjunctivitis.

Primary endpoint=ACR20 response at week 24.

mNRI, a preferred method for analyzing long term efficacy, imputes missing data due to study drug (e.g., inadequate response, adverse event, or lack of efficacy), as nonresponse; whereas, missing data due to other reasons (e.g., missed visits, lost to follow-up) is included as a predicted value based on statistical modeling of observed data.

Inadequate responders (<20% improvement in tender and in swollen joint counts) at week 16 were analyzed as nonresponders after week 16 until the primary endpoint.

After week 24, patients knew they were taking active treatment, but remained blind to the dose until the last patient completed week 24. The uncontrolled extension period of the study has limitations (e.g., no placebo comparisons, patients remaining in the study may be those with better results).

In an mNRI analysis of patients receiving Taltz, 83% of patients achieved LDI-B=0 at week 52 and 77% at week 108.

SELECT 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.

Indications and Important Safety Information
Indications

Taltz is indicated for your adult patients with active psoriatic arthritis (PsA).

Taltz is also indicated for your adult patients 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 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 patients with psoriatic arthritis. 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
During Taltz treatment, monitor patients for onset or exacerbations of 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 in patients with plaque psoriasis.

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 profile observed in patients with psoriatic arthritis was consistent with the safety profile in patients with plaque psoriasis, with the exception of influenza and conjunctivitis.

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.
