DUBLIN – Immatics Biotechnologies GmbH is banking $50 million up front and could earn up to $550 million more in per-product milestones from an adoptive cell therapy deal in solid tumor indications with Glaxosmithkline plc, which initially involves two autologous cell therapies engineered to express T-cell receptors (TCRs) that bind novel cancer targets. Immatics would receive royalties on sales of any approved therapies.
