OPAL Broaden was a 12-month, double-blind phase III trial. Patients received tofacitinib 5 mg twice daily (BID; n = 107), tofacitinib 10 mg BID (n = 104), or ADA 40 mg once every 2 weeks (n = 106), all with 1 background csDMARD. Radiographs (baseline and Month 12) were scored using the van der Heijde-modified total Sharp score (mTSS) for PsA. Radiographic nonprogression was defined as an increase from baseline in mTSS \u2264 0.5, \u2264 0, or \u2264 0.66. Changes from baseline in mTSS and nonprogression (\u2264 0.5 increase from baseline in mTSS) were analyzed by baseline C-reactive protein (CRP) &gt; 2.87 or \u2264 2.87 mg\/l. Baseline predictors of radiographic progression were analyzed.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results.<\/jats:title><jats:p>At Month 12, &gt; 90% of patients receiving tofacitinib or ADA met all radiographic nonprogression criteria. Mean changes from baseline through Month 12 in mTSS, erosion, and joint space narrowing scores were close to 0. Changes in radiographic outcomes were minimal, irrespective of baseline CRP levels &gt; 2.87 or \u2264 2.87 mg\/l, with a small numerical difference observed for tofacitinib 5 mg BID. A significant relationship was observed between baseline CRP level and increases from baseline in mTSS &gt; 0.5 at Month 12.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion.<\/jats:title><jats:p>Elevated CRP levels at baseline were associated with greater structural progression. Changes in radiographic outcomes were minimal regardless of CRP levels.
