Real-world clinical effectiveness and safety of CT-P10 in patients with diffuse large B-cell lymphoma: An observational study in Europe
Abstract
The rituximab biosimilar CT-P10 is approved for the treatment of non-Hodgkin lymphoma. Previous studies have demonstrated clinical similarity between CT-P10 and reference rituximab. However, real-world data relating to treatment in patients with DLBCL with rituximab biosimilars are limited. This study collected real-world data relating to the effectiveness and safety of CT-P10 treatment from the medical records of 389 patients with DLBCL (24 centers, five European countries). For the primary outcome (clinical effectiveness), overall survival (OS), progression-free survival (PFS), and best response (BR) were assessed. The percentage (95% confidence interval [95% CI]) of patients alive at 12-, 18-, and 30 months postindex (initiation of CT-P10) was 86% (82.4%–89.4%), 81% (76.9%–84.9%), and 76% (71.2%–80.1%), respectively. The PFS rate (percent, [95% CI]) at 12-, 18-, and 30 months postindex was 78% (74.2%–82.5%), 72% (67.9%–76.9%), and 67% (61.9%–71.7%), respectively. Median OS/PFS was not reached. For 82% (n = 312) of patients, the BR to CT-P10 was a complete response. Adverse events were consistent with known effects of chemotherapy. This international, multicenter study provides real-world data on the safety and effectiveness profile of CT-P10 for DLBCL treatment and supports the adoption of CT-P10 for the treatment of DLBCL.
