SPIRIT-P2 is one of two pivotal trials conducted with ixekizumab in patients with psoriatic arthritis; the other is SPIRIT-P1, which was conducted in biologic-naive patients (Ann Rheum Dis. 2017;76[1]:79-87). Investigators recently reported 1-year data from it (J Rheumatol. 2018;45[3]:367-77.).
Eli Lilly, which markets ixekizumab as Taltz, sponsored the study. Dr. Marzo-Ortega disclosed receiving honoraria from AbbVie, Celgene, Eli Lilly, Novartis, and UCB, and honoraria and research funding from Janssen and Pfizer. Several other authors reported disclosures with many manufacturers of biologics for psoriatic arthritis, including Eli Lilly.
