Caleb Stubbs's questions to Allogene Therapeutics (ALLO) leadership

Question · Q1 2025

Representing Sami Corwin, Caleb Stubbs asked if the site-related challenges seen in ALPHA3 are expected at ex-U.S. sites and if there are plans to activate ex-U.S. sites for the ALLO-329 RESOLUTION study.

Answer

EVP of R&D and CMO Dr. Zachary Roberts anticipates a smoother activation for ALPHA3 ex-U.S. due to lessons learned and less fragmented care pathways abroad. For ALLO-329, he stated the near-term focus is on U.S. sites, but the company remains open to future international expansion.
