Safety and Efficacy of Golimumab in Indian Patients with Active Spondyloarthritis of Ankylosing Spondylitis or Psoriatic Arthritis: A Multicenter, Noncomparative, Open-Label, Real-World Study.

ABSTRACT

BACKGROUND: The safety and efficacy of tumor necrosis factor-α (TNF-α) inhibitor therapy for most common rheumatological diseases, ankylosing spondylitis (AS), and psoriatic arthritis (PsA) in controlled clinical trials is well-studied. This study evaluated subcutaneous (SC) golimumab in Indian patients with active spondyloarthritis (SpA) of AS or PsA in a real-world setting. MATERIALS AND METHODS: This phase 4, multicenter, prospective, non-comparative, interventional, 24-week study was performed in patients (age ≥18 years) with active SpA of AS or PsA (NCT03733925). Golimumab 50 mg was given subcutaneously to the patients every 4 weeks. Safety was assessed. The proportion of patients with AS and PsA achieving ≥20% improvement in the Assessment of SpA International Society 20 (ASAS20) criteria and American College of Rheumatology 20 (ACR20) responses, respectively, at weeks 14 and 24 were efficacy endpoints. RESULTS: Of the 100 patients enrolled (men 78 [78.0%]; mean age 36.7 [12.02] years), 94 (94.0%) patients completed the study. Treatment-emergent adverse events with golimumab were observed in 29/100 (29.0%) patients, and nasopharyngitis and upper respiratory tract infection (5.0% each) were the most common (≥5%). Deaths were not reported. At week 14, 74.5% (95% confidence interval [CI] 59.7; 86.1%) of patients with AS and 84.6% (95% CI 69.5; 94.1%) of patients with PsA achieved ASAS20 and ACR20 responses, which were sustained at week 24 (ASAS20 66.0% [95% CI 50.7, 79.1%]; ACR20 93.2% [95% CI 81.3, 98.6%]), respectively. CONCLUSION: Golimumab (50 mg) administered subcutaneously was safe and effective in Indian patients with active SpA of AS or PsA during the 24-week study period with no new safety signals.
