May 2023Series BKite Pharma; Delos Capital; Bioluminescence Ventures; SymBiosis LLC$50MEnsoma is a Boston-based genomic medicines company developing one-time, in vivo treatments that precisely engineer cells of the hematopoietic system. The company's Engenious platform leverages world-class technologies for in vivo delivery and genome engineering, targeting diseases including cancer, autoimmunity, hemoglobinopathies, and genetic disorders like X-linked CGD. The platform is designed to work without stem cell collection or prior myeloablative conditioning, enabling single-injection outpatient delivery. On May 16, 2023, Ensoma announced the closing of a $50 million Series B extension, bringing the total Series B round size to $135 million. The $50 million extension was contributed by new investors Kite (a Gilead Company), Bioluminescence Ventures, and Delos Capital, alongside existing investor SymBiosis. These investors joined a broader syndicate of leading healthcare funds to advance development of the Engenious in vivo engineered cell therapy platform and the pipeline of genomic medicines for immuno-oncology, genetic disease, and other therapeutic applications. Ensoma progressed to clinical stage by September 2025, announcing a $53 million financing and the initiation of a Phase 1/2 trial for EN-374 to treat X-linked CGD, with manufacturing infrastructure in place to support human trials.

The company's proprietary Engenious vector technology platform enables genetic medicines to be injected directly into the body without requiring stem cell collection or myeloablative conditioning, addressing delivery challenges that had limited previous genetic medicine approaches. The Series A financing round raised $70 million led by 5AM Ventures (which also served as a co-founder and seed investor) with participation from F-Prime Capital, Takeda Ventures, Viking Global Investors, Cormorant Asset Management, RIT Capital Partners, Symbiosis II, and Alexandria Venture Investments. In parallel with the equity financing, Ensoma entered into a strategic collaboration with Takeda Pharmaceutical Company Limited worth up to $1.25 billion, including potential upfront and preclinical research payments totaling $100 million, with Takeda receiving an exclusive worldwide license to the Engenious platform for up to five rare genetic disease indications. Founding CEO Kush M. Parmar, who was also a managing partner at 5AM Ventures, led the company's scientific approach aimed at making genomic medicine and stem cell technology accessible globally. As a newly launched company, Ensoma had no commercial revenue at the time of this financing round.
