The platform targets oncology indications like multiple myeloma (bivalent BCMA) and acute myeloid leukemia (CD123), with expansion into solid tumors and autoimmune diseases. Arcellx was founded by David Hilbert, PhD, and led by a team of experienced scientists and executives. On October 3, 2019, Arcellx closed an oversubscribed $85 million Series B financing, co-led by new investors Aju IB Investment and Quan Capital, with participation from Mirae Asset Venture Investment, Mirae Asset Capital, LG Technology Ventures, JVC Investment Partners, Clough Capital Partners funds, and existing investors Novo Holdings, SR One, New Enterprise Associates (NEA), and Takeda Ventures. This followed a $27 million Series A earlier in 2019 from NEA, Novo, Takeda Ventures, and SR One. The financing included $41.8 million secured in August per SEC filings. Concurrently, Hugo Beekman from Aju IB and Lewis (Rusty) Williams from Quan Capital joined the board. Proceeds fund clinical development of the BCMA-targeted therapy for multiple myeloma and CD123-targeted therapy for AML, plus earlier-stage programs. In August 2019, Arcellx signed a deal with Pfenex for expression technology access, involving development funding and milestones from $2.6 million to $18 million per product, plus royalties on sales. The round positions Arcellx to compete in next-generation cell therapy against players like Autolus, Senti Bio, and Unum Therapeutics, emphasizing improved safety and efficacy. Investors highlighted the platform's potential inflection point for better patient outcomes in hematological cancers and beyond.
