Various factors may cause material differences between Allogene’s expectations and actual results, including risks and uncertainties related to: clinical development risks, including our novel allogeneic CAR T approach and the unproven first-line consolidation setting in LBCL, the possibility that early or Phase 1 data may not predict later outcomes, trial delays or enrollment challenges, and adverse events (including those previously observed in certain ALPHA3 arms); contractual and counterparty risks; regulatory risks, including potential FDA or foreign authority disagreement with plans or interpretations, requests for additional data or trials, and possible requirements related to MRD assays; manufacturing and CMC risks, including challenges in consistent, scalable manufacturing and technology implementation that could affect timelines, outcomes, or availability; reliance on third parties, including licensors and collaborators (e.g., Cellectis, Servier, and Foresight Diagnostics); and financial risks relating to continued operating losses, the need for additional financing, and the possibility of not meeting financial guidance.
