Chinese CAR-T player books a megaround to drive bustling cell therapy portfolio through the clinic

China has quickly emerged as a major driver of oncology R&D in recent years, particularly in cell therapies where the potential for cheaper development has investors drooling. Now, one player, with a handful of early data, is swimming in a new round of investor cash.
IASO Bio has closed a $108 million Series C that the Chinese and California-based biotech said it will use to advance its slate of cell therapy lead programs, while also propping up a roster of next-gen allogeneic cell therapies for the future, according to a release.
The round was led by CDH Baifu, and followed by CCB International, with participation from Everbright Limited, Co-Stone Capital, CNCB Capital and Plaisance Capital with current shareholder GL Ventures also jumping on board.
The newest funding comes just months after IASO and its partner Innovent revealed Phase I data from its BCMA CAR-T candidate IBI326 — now known as CT103A — which posted a 97.1% response rate in 35 patients with relapsed or refractory multiple myeloma. In those patients treated with one of three doses of IBI326, 29 (or 82.9%) achieved a very good partial response or greater, and 20 (57.1%) saw a complete response or stringent complete response. Of 34 patients evaluable for minimal residual disease (MRD), all achieved MRD negativity, according to the companies.
The analysis includes eight patients with extramedullary multiple myeloma (EMM), and 10 patients who had previously received a murine BCMA CAR-T treatment, all of whom saw a response, Innovent and IASO reported. Among the 10 patients who had taken a murine BCMA CAR-T treatment, eight achieved a very good partial response or better, one saw a partial response and another reached stable disease.
IASO also sports a novel CD19/CD22 CAR-T, which is currently in human trials in China, and a CD5 CAR-T, which is currently in preclinical development.
