OBJECTIVES: The 2023 EULAR guidelines for systemic sclerosis (SSc) recommend biologics (rituximab, tocilizumab), mycophenolate mofetil (MMF), and nintedanib in addition to cyclophosphamide for interstitial lung disease (ILD). This study investigated recent actual use of these drugs in Japan.
METHODS: We analysed data from a Japanese hospital claims database (2020-3), identifying patients with SSc disease codes (ICD-10 M34.x) and/or ILD codes. Patients with coexisting autoimmune disease codes were also included.
RESULTS: Of 14,522 SSc patients, 2080 (14.3%) received small-molecule drugs and 618 (4.3%) received biologics. For SSc, common first small-molecule drugs were methotrexate (24.2%), nintedanib (19.5%), tacrolimus (17.9%), and MMF (16.8%); common first biologics were rituximab (44.2%) and tocilizumab (29.1%). Of 4890 SSc-ILD patients, 1081 (22.1%) received small-molecule drugs and 282 (5.8%) received biologics. For SSc-ILD, common first small-molecule drugs were nintedanib (30.8%), tacrolimus (20.9%), and MMF (18.3%); common first biologics were rituximab (51.8%) and tocilizumab (25.2%). Rituximab showed the greatest increase in use for both SSc and SSc-ILD between 2020 and 2023. Common subsequent treatments following rituximab or intravenous cyclophosphamide (which are typically administered for a limited duration) were nintedanib, MMF, and rituximab.
CONCLUSIONS: Recent actual drug use in Japan has been aligning increasingly closely with the EULAR recommendations.
