Evaluation of Real-world treatment patterns in Japanese patients with cGVHD: A retrospective claims database study
摘要
This retrospective cohort study using the medical data vision (MDV) database included adult patients who had confirmed diagnosis of cGVHD between 2003 and 2023, were prescribed a steroid prior to diagnosis of cGVHD, and received mycophenolate mofetil (MMF), ibrutinib, or ruxolitinib as second- or later-line therapy. Duration of treatment (DoT) and steroid dose reduction during second-line therapy were assessed. Of the 1489 patients whose data were retrieved, 854 were included (median [range] age: 54 [18.0–83.0] years; males: 518 [60.7%]; mean [SD] Charlson Comorbidity Index score: 7.5 [3.5]). Data on second or later lines of treatment were available for 226 patients. The most common second-line therapy used after first-line steroid treatment was MMF (110 [48.67%]), followed by ibrutinib (88 [38.94%]) and ruxolitinib (28 [12.39%]). Median DoT (days) was 95 for MMF, 86 for ibrutinib, and 30 for ruxolitinib. Steroid doses were mostly kept below 0.5 mg/kg/day under all the 3 second-line treatments. These real-world data provide valuable insights into the management of cGVHD with the therapies currently used in Japan.
