Two years follow-up of an open-label pilot study of treatment with rituximab in patients with early diffuse cutaneous systemic sclerosis
2018
AbstractObjectives: Following results in open-label studies of rituximab in patients with systemic sclerosis, a Belgian three-centre initiative was launched to explore safety and efficacy of rituximab in early, diffuse cutaneous systemic sclerosis (dcSSc).Methods: Open-label study of 17 patients with early dcSSc, treated with two courses of rituximab, at month 0 and 6. Clinical examination, lung function testing, echocardiography, disease activity score (DAS) and functional status were performed at baseline and over 24 months of follow-up.Results: Modified Rodnan skin score (MRSS) changed significantly over time, with a mean of 25.5 (standard deviation [SD] 6.0) at baseline to 12.6 (SD 5.1) at month 24 (Mixed Model Analysis [MMA] p < 0.0001), which is a decrease of 51% at month 24 vs. baseline. DAS showed significant decrease over the total study period, with a score of 4.1 (SD 1.7) at baseline to 1.5 (SD 1.8) at month 24 (MMA p < 0.0001). Additionally, this was significant at all time points vs. baseline...
