Moving from Phase 1a to Phase 1b Continuous Improvement of Key Aspects that May Influence Clinical Outcome 13 Our Focus in Phase 1a • Safety • Biological activity • Initial signs of clinical activity Our Focus in Phase 1b • Safety • Durability of response at 6 months and beyond to pave the way for registration trials We continue to improve key determinants as we move from Phase 1a into Phase 1b 1. Higher T cell dose: Only RP2D or exploratory DL5 2. Enhanced cell product: Implementation of manufacturing enhancements (e.g. monocyte depletion, see appendix) focusing on robustness, quality, and speed of product release 3. “Real life” patients: Working with more disease area experts to reduce the fraction of very heavily pre - treated patients with extreme disease burden who have exhausted standard of care and have undergone multiple clinical trials I M A 203
