Clarifying Questions (5 mins)

• Looking at the CAR-T therapy landscape, I'm thinking about the current production capacity. Could you share our current annual production volume and target growth rate?

Why it matters: Determines the scale of improvement needed and informs prioritization. Expected answer: Current capacity of 1000 treatments/year, aiming for 10x growth in 5 years. Impact on approach: Would focus on radical process innovations for exponential scaling.

• Considering the complexity of CAR-T production, I'm curious about our current bottlenecks. What stage of the manufacturing process is currently the most time-consuming or resource-intensive?

Why it matters: Identifies the critical areas for improvement. Expected answer: T cell expansion phase takes the longest, about 10-14 days. Impact on approach: Would prioritize solutions to accelerate cell expansion or find alternatives.

• Given the personalized nature of CAR-T therapy, I'm wondering about our current level of automation. What percentage of our production process is currently automated versus manual?

Why it matters: Determines potential for efficiency gains through further automation. Expected answer: 60% automated, with key manual steps in cell selection and quality control. Impact on approach: Would explore advanced robotics and AI for manual processes.

• Considering the regulatory landscape, I'm thinking about FDA approvals. What's our current timeline for getting new production methods approved, and how might this impact our scaling efforts?

Why it matters: Influences the feasibility and timeline of implementing new solutions. Expected answer: 12-18 months for significant changes, 6-9 months for minor improvements. Impact on approach: Would balance innovative solutions with incremental improvements.
