Kelly Shi's questions to Allogene Therapeutics Inc (ALLO) leadership • Q2 2025
Question
Kelly Shi asked whether the timing of identifying MRD-positive patients post-R-CHOP could impact MRD conversion rates or EFS, and also inquired about the prior clinical evidence used to establish the efficacy bar for the pivotal frontline consolidation study.
Answer
David Chang, CEO, stated that the MRD testing window is well-defined and not expected to significantly impact outcomes. Zachary Roberts, CMO, added there is no data suggesting timing would influence EFS. For the efficacy bar, Dr. Roberts referenced the approximately 30% efficacy delta seen in second-line CAR T trials as the benchmark, noting ALPHA-three is pioneering this prospective analysis.
