Clarifying Questions (5 mins)

• Looking at the product context, I'm thinking about the current accuracy and sensitivity of the NeXT Personal assay. Could you provide more information on the current detection rates and false positive/negative rates?

Why it matters: Determines the baseline for improvement and helps identify specific areas for enhancement. Expected answer: Current detection rate is around 70% with a 5% false positive rate. Impact on approach: Would focus on improving sensitivity for early-stage cancers or reducing false positives.

• Considering user behavior, I'm curious about the typical patient journey. How frequently are patients tested, and what's the process for follow-up on positive results?

Why it matters: Helps understand user pain points and potential areas for streamlining the process. Expected answer: Patients are typically tested annually, with positive results leading to immediate follow-up imaging and biopsy. Impact on approach: Might focus on improving testing frequency or enhancing the follow-up process.

• Examining external factors, I'm interested in the competitive landscape. How does NeXT Personal compare to other liquid biopsy tests in the market in terms of accuracy and cost?

Why it matters: Identifies areas where we can differentiate and improve relative to competitors. Expected answer: NeXT Personal has slightly higher accuracy but is more expensive than some competitors. Impact on approach: Could focus on cost reduction or further improving accuracy to justify the premium price.

• Considering the product lifecycle, where is NeXT Personal in its development, and what are the key areas of focus for the next iteration?

Why it matters: Helps align our improvement efforts with the overall product strategy. Expected answer: The product is in its growth phase, with a focus on expanding the range of detectable cancer types. Impact on approach: Would prioritize improvements that support the expansion of detectable cancers.
