Shanghai – September 26, 2026 -- IASO Biotechnology's CAR-T therapy FUCASO achieved a 95.9% objective response rate and 77.2% complete/stringent complete response rate in a real-world study of 281 heavily pretreated Chinese patients with relapsed or refractory plasma cell neoplasms, data presented at the 2026 International Myeloma Society Annual Meeting show.
Real-world cohort skews higher-risk than pivotal trial population
The multicenter study tracked patients treated since FUCASO's June 2023 launch across China. Median age was 61 years, with 18.7% aged 70 or older, and patients had received a median of four prior therapy lines, up to 12. Prior anti-CD38 exposure reached 84.0%, 27.4% were penta-exposed, and 46.9% had undergone autologous stem cell transplantation. High-risk cytogenetic abnormalities affected 82.4% of patients, 50.5% were ISS stage III, 7.8% had plasma cell leukemia, and 47.0% presented extramedullary disease.
