Abstract

Background/Objective This post hoc analysis assessed efficacy and safety of intravenous (IV) golimumab in ankylosing spondylitis (AS) patients with early disease (ED) versus late disease (LD). Methods The phase 3, double-blind, GO-ALIVE study randomized patients to IV golimumab 2 mg/kg at weeks 0 and 4 and then every 8 weeks through week 52, or placebo at weeks 0, 4, and 12 with crossover to IV golimumab at week 16. Clinical efficacy was assessed by ≥20% improvement in Assessment of Spondyloarthritis International Society response criteria (ASAS20), ≥50% improvement in Bath Ankylosing Spondylitis Disease Activity Index (BASDAI 50), and Ankylosing Spondylitis Disease Activity Score (ASDAS) <1.3 (inactive disease). Using self-reported duration of inflammatory back pain (IBP), patients were grouped into quartiles: first = ED and fourth = LD. Descriptive statistics summarized efficacy and safety findings through 1 year. Results Early disease patients (n = 60) were 10 years younger and had shorter median AS (IBP) symptom duration (2-3 years) versus LD patients (n = 52; 21-24 years). At week 16, numerically higher proportions of golimumab- than placebo-treated patients achieved ASAS20 (ED: 71% vs. 32%; LD: 67% vs. 21%), BASDAI 50 (ED: 40% vs. 12%; LD: 33% vs. 7%), and ASDAS <1.3 (ED: 17% vs. 4%; LD 8% vs. 0%) regardless of IBP duration. Efficacy was durable through 1 year of treatment; however, response rates were numerically higher in patients with ED versus LD. Through week 60, adverse events and serious adverse events, respectively, were reported by 46% and 3% of ED patients and 61% and 2% of LD patients. Conclusion Prompt diagnosis of AS and early treatment with IV golimumab may yield more robust improvements in disease activity.
