Description

11 DESCRIPTION Ixekizumab is a humanized immunoglobulin G subclass 4 (IgG4) monoclonal antibody (mAb) with neutralizing activity against IL-17A. Ixekizumab is produced by recombinant DNA technology in a recombinant mammalian cell line and purified using standard technology for bioprocessing. Ixekizumab is comprised of two identical light chain polypeptides of 219 amino acids each and two identical heavy chain polypeptides of 445 amino acids each and has a molecular weight of 146,158 Daltons for the protein backbone of the molecule. TALTZ injection is a sterile, preservative free, clear and colorless to slightly yellow solution, for subcutaneous use available as 80 mg of ixekizumab in a 1 mL single-dose prefilled autoinjector or a single-dose prefilled syringe, 40 mg of ixekizumab in a 0.5 mL single-dose prefilled syringe, or 20 mg of ixekizumab in a 0.25 mL single-dose prefilled syringe. The prefilled autoinjector and prefilled syringe each contain a 1 mL glass syringe with a fixed 27 gauge ½ inch needle. The TALTZ 80 mg prefilled autoinjector and prefilled syringe are manufactured to deliver 80 mg of ixekizumab. The TALTZ 40 mg prefilled syringe is manufactured to deliver 40 mg of ixekizumab.

Side Effects (Adverse Reactions)

6 ADVERSE REACTIONS The following adverse drug reactions are discussed in greater detail in other sections of the label: Infections [see Warnings and Precautions ( 5.1 )] Hypersensitivity Reactions [see Contraindications ( 4 ) and Warnings and Precautions ( 5.3 )] Eczematous Eruptions [see Warnings and Precautions ( 5.4 )] Inflammatory Bowel Disease [see Warnings and Precautions ( 5.5 )] Most common (≥1%) adverse reactions associated with TALTZ treatment are injection site reactions, upper respiratory tract infections, nausea, and tinea infections. ( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact Eli Lilly and Company at 1-800-545-5979 (1-800-LillyRx) or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch. 6.1 Clinical Trials Experience Because clinical trials are conducted under widely varying and controlled conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice. Adult Plaque Psoriasis Weeks 0 to 12 : Three placebo-controlled trials in subjects with plaque psoriasis were integrated to evaluate the safety of TALTZ compared to placebo for up to 12 weeks. A total of 1167 subjects (mean age 45 years; 66% men; 94% White) with plaque psoriasis received TALTZ (160 mg at Week 0, 80 mg every 2 weeks [Q2W] for 12 weeks) subcutaneously. In two of the trials, the safety of TALTZ (use up to 12 weeks) was also compared with an active comparator, U.S. approved etanercept [see Clinical Studies ( 14 )] . In the 12-week, placebo-controlled period, adverse events occurred in 58% of the TALTZ Q2W group (2.5 per subject-year of follow-up) compared with 47% of the placebo group (2.1 per subject-year of follow-up). Serious adverse events occurred in 2% of the TALTZ group (0.07 per subject-year of follow-up), and in 2% of the placebo group (0.07 per subject-year of follow-up). Table 2 summarizes the adverse reactions that occurred at a rate of at least 1% and at a higher rate in the TALTZ group than in the placebo group during the 12-week placebo-controlled period of the pooled clinical trials. Table 2: Adverse Reactions Occurring in ≥1% of the TALTZ Group and More Frequently than in the Placebo Group in the Plaque Psoriasis Clinical Trials through Week 12 a Upper respiratory tract infections cluster includes nasopharyngitis and rhinovirus infection. b U.S. approved etanercept. Adverse Reactions TALTZ 80 mg Q2W (N=1167) n (%) Etanercept b (N=287) n (%) Placebo (N=791) n (%) Injection site reactions 196 (17) 32 (11) 26 (3) Upper respiratory tract infections a 163 (14) 23 (8) 101 (13) Nausea 23 (2) 1 (<1) 5 (1) Tinea infections 17 (2) 0 1 (<1) Adverse reactions that occurred at rates less than 1% in the TALTZ group and more frequently than in the placebo group during the 12-week induction period included rhinitis, oral candidiasis, urticaria, influenza, conjunctivitis, inflammatory bowel disease, and angioedema. Weeks 13 to 60 : A total of 332 subjects received the recommended maintenance regimen of TALTZ 80 mg dosed every 4 weeks. During the maintenance period (Weeks 13 to 60), adverse events occurred in 80% of subjects treated with TALTZ (1.0 per subject-year of follow-up) compared to 58% of subjects treated with placebo (1.1 per subject-year of follow-up). Serious adverse events were reported in 4% of subjects treated with TALTZ (0.05 per subject-year of follow-up) and none in the subjects treated with placebo. Weeks 0 to 60 : Over the entire treatment period (Weeks 0 to 60), adverse events were reported in 67% of subjects treated with TALTZ (1.4 per subject-year of follow-up) compared to 48% of subjects treated with placebo (2.0 per subject-year of follow-up). Serious adverse events were reported in 3% of subjects treated with TALTZ (0.06 per subject-year of follow-up), and in 2% of subjects treated with placebo (0.06 per subject-year of follow-up).

4 CONTRAINDICATIONS TALTZ is contraindicated in patients with a previous serious hypersensitivity reaction, such as anaphylaxis, to ixekizumab or to any of the excipients [see Warnings and Precautions ( 5.3 )] . Serious hypersensitivity reaction to ixekizumab or to any of the excipients. ( 4 )

Pregnancy and Breastfeeding

8.1 Pregnancy Pregnancy Exposure Registry There is a pregnancy exposure registry that monitors pregnancy outcomes in women exposed to TALTZ during pregnancy. Pregnant women exposed to TALTZ are encouraged to enroll in the TALTZ Pregnancy Registry by calling 1-800-284-1695. Contact information for the registry is also available on http://www.pregnancyregistry.lilly.com. Risk Summary Available data from the published literature and the pharmacovigilance database with TALTZ use in pregnant women are insufficient to evaluate for a drug-associated risk of major birth defects, miscarriage or other adverse maternal or fetal outcomes. Human IgG is known to cross the placental barrier; therefore, TALTZ may be transmitted from the mother to the developing fetus. An embryofetal development study conducted in pregnant monkeys during organogenesis at doses up to 19 times the maximum recommended human dose (MRHD) revealed no evidence of harm to the developing fetus. When dosing was continued until parturition, neonatal deaths were observed at 1.9 times the MRHD [see Data] . The clinical significance of these nonclinical findings is unknown. The background risk of major birth defects and miscarriage for the indicated population is unknown. All pregnancies have a background risk of birth defect, loss, or other adverse outcomes. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2 to 4% and 15 to 20%, respectively. Data Animal Data An embryofetal development study was conducted in cynomolgus monkeys administered ixekizumab. No malformations or embryofetal toxicity were observed in fetuses from pregnant monkeys administered ixekizumab weekly by subcutaneous injection during organogenesis to near parturition at doses up to 19 times the MRHD (on a mg/kg basis of 50 mg/kg/week). Ixekizumab crossed the placenta in monkeys. In a pre- and post-natal development toxicity study, pregnant cynomolgus...
