Shanghai – September 26, 2026 -- IASO Biotechnology reported a 90% objective response rate and 90% minimal residual disease (MRD) negativity rate for its BCMA-targeted in vivo CAR-T therapy IASO206, generated via a single intravenous infusion without lymphodepleting chemotherapy, in first-in-human Phase 1 data presented as a late-breaking oral session (LBA-11) at the 2026 International Myeloma Society Annual Meeting.

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.

Shanghai – September 25, 2026 -- IASO Biotechnology reported an 88.9% objective response rate for its dual-targeted CAR-T therapy RD140 in a first-in-human Phase 1 trial of nine heavily pretreated multiple myeloma and plasma cell leukemia patients, with the response rate reaching 100% in the higher-dose cohort.

Shanghai – September 25, 2026 -- A retrospective analysis of 102 multiple myeloma patients treated with IASO Bio's FUCASO CAR-T therapy found that patients maintaining sustained minimal residual disease (MRD) negativity showed a median CAR-T cell persistence of 463 days, compared with 272 days in patients who experienced MRD conversion — a gap of roughly 191 days. The data, drawn from the pivotal FUMANBA-1 registration study, were presented as a poster (Abstract No. PA-469) at the 2026 International Myeloma Society Annual Meeting.
