Wollenhaupt et al. undertook a post-hoc analysis of data from eight Phase 3 and 3b/4 clinical trials to assess change from baseline (Δ) weight and BMI in patients with moderate to severe RA receiving TOF through 12 months. Additionally, Wollenhaupt et al. evaluated correlations between baseline/changes in disease activity, baseline CRP, and changes in lipids with Δweight and BMI. Wollenhaupt et al. showed that mean Δweight and BMI increased over time and were greater with TOF (all doses) versus placebo at Months 3 and 6, and with TOF monotherapy versus combination therapy, at Months 3, 6, and 12. The correlation and sensitivity analyses showed weak correlation between Δweight or BMI with TOF and DAS28-4(ESR), baseline CRP or lipid changes.
