7 Ixekizumab is FDA approved for adults with active psoriatic arthritis DOSAGE AND ADMINISTRATION Plaque Psoriasis TALTZ is administered by subcutaneous injection. The recommended dose is 160mg (two 80 mg injections) at Week 0, followed by 80mg at Weeks 2, 4, 6, 8, 10, and 12, then 80mg every 4weeks. Psoriatic Arthritis The recommended dose is 160 mg by subcutaneous injection (two 80 mg injections) at week 0, followed by 80 mg every 4 weeks. For psoriatic arthritis patients with coexistent moderate-tosevere plaque psoriasis, use the dosing regimen for plaque psoriasis

10 Secukinumab is FDA Approved for Psoriasis Indication: for the treatment of moderate-to-severe plaque psoriasis in adult patients who are candidates for systemic therapy or phototherapy Dosage: Recommended dose is 300 mg by subcutaneous injection at weeks 0, 1, 2, 3, and 4, followed by 300 mg every 4 weeks. For some patients, a dose of 150 mg may be acceptable FDA: Food and Drug Administration.

11 Secukinumab is Indicated for PsA in the United States 2.2 Psoriatic Arthritis For psoriatic arthritis patients with coexistent moderate to severe plaque psoriasis, use the dosing and administration recommendations for plaque psoriasis [see Dosage and Administration (2.1)] For other psoriatic arthritis patients, administer secukinumab with or without a loading dosage by subcutaneous injection. The recommended dosage: o o o With loading dosage is 150 mg at weeks 0, 1, 2, 3, and 4 and every 4 weeks thereafter Without a loading dosage is 150 mg every 4 weeks If a patient continues to have active psoriatic arthritis, consider a dosage of 300 mg Secukinumab may be administered with or without methotrexate Package Insert. PsA: psoriatic arthritis.
