Q2 2026 Quarterly Data Report Contents Introduction The second quarter of 2026 marked a renewed acceleration in regulatory activity across thegene, cell, and RNA therapy landscape, with eight new approvals globally following acomparatively subdued first quarter. Five gene therapies received marketing authorization,including treatments for hearing loss, cancer, and limb ischemia. Moderna's mCombriaxbecame the latest approved RNA therapy in the European Union for seasonal influenza andCOVID-19, while Japan authorized two non-genetically modified cell therapies forepidermolysis bullosa and meniscal injuries. Together, these approvals reflect continueddiversification across therapeutic modalities and indications, bringing global totals to45approved gene therapies (including genetically modified cell therapies),38 RNA therapies,and 77 non-genetically modified cell therapies. Innovation also accelerated during the quarter, with 11 new mRNA-encoded CAR-T celltherapies entering development, matching the total reported across all of 2025. This rapidexpansion signals growing confidence in next-generation engineering approaches designedto improve the scalability and accessibility of cell therapies. Cartesian Therapeutics' PhaseIII candidate, Descartes-08, remains the most advanced program in this emerging modality. Industry activity strengthened alongside scientific progress. Total dealmaking increased15%quarter over quarter to 118 transactions—the highest quarterly total in the past year—while earlystage financing rebounded sharply, with20 companies raising a combined$500.4million in seed or Series A funding. Following the disciplined portfolio optimizationobservedin late 2025 and the steady regulatory progress seen in Q1, Q2suggests the fieldhas regained momentum across regulatory, scientific, and investment fronts, reinforcingcontinued confidence in the long-term growth of advanced molecular therapies.
