Roger Song's questions to ALX ONCOLOGY HOLDINGS (ALXO) leadership • Q2 2025
Question
Roger Song of Jefferies questioned the consistency of data across different CD47 expression cutoffs, the applicability of the 10% cutoff to other programs, and the biological rationale for this expression level.
Answer
CEO Jason Lettmann stated that the positive effect was robust and consistent across various cutoffs, with full data on ORR, DOR, PFS, and OS to be presented in Q4. He noted the cutoff for future studies is to be determined. Both Lettmann and CMO Alan Sandler referenced literature supporting CD47 as a well-studied negative prognostic marker, providing a strong biological basis for the strategy.
