Management Comments

• Delivering therapies that can positively impact patients' lives is our mission, said Rami Elghandour, Arcellx's Chairman and Chief Executive Officer.
• We are pleased that minimal residual disease negativity has been added as a dual primary endpoint to the iMMagine-3 protocol in addition to progression-free survival.

• Its an inspiring time at Arcellx!
• We continue to attract outstanding talent who recognize the opportunity to play a part in advancing our category-defining therapy and value our diverse and inclusive culture, which allows them to do what they do best every day.

Industry Context

Arcellx is operating in the competitive field of cell therapy, focusing on innovative immunotherapies for cancer. The addition of MRD negativity as a dual primary endpoint in the iMMagine-3 study reflects a growing emphasis on achieving deeper and more durable responses in multiple myeloma treatment, aligning with trends in the broader hematology space.

Comparison to Industry Standards

• Arcellx's cash runway extending into 2028 is relatively strong compared to other clinical-stage biotech companies, providing financial flexibility for ongoing clinical trials and preparations for potential commercialization.
• Companies like Legend Biotech and 2seventy bio are also focused on cell therapies for multiple myeloma, and Arcellx's anito-cel will compete with their products if approved.
• The addition of MRD negativity as a primary endpoint aligns with the FDA's increasing focus on this measure as an indicator of treatment efficacy, similar to trends seen in other hematologic malignancies.
