Background

LifeArc Ventures participated in Cytospire's £61m Series A in May 2026 alongside Abingworth, Servier Ventures, Sound Bioventures, and Medical Incubator Japan. Cytospire is developing CYT X300, a pan-gamma delta T cell engager targeting solid tumours; LifeArc's focus on early translational oncology and immunology makes this a strategic-fit investment.

LifeArc Ventures is the investment Arm of LifeArc, a UK not-for-profit medical research organisation. LifeArc was originally the Medical Research Council's technology transfer office; it became independent and has since commercialised assets including contributions to pembrolizumab (Keytruda), generating over £1.4bn in proceeds that fund its ongoing medical research grant programme. LifeArc Ventures deploys capital from this endowment into early-stage biotech consistent with LifeArc's translational Science mission, with a preference for UK-based or UK-academic-origin companies.
