Clarifying Questions (3 minutes)

• Looking at the timing, I'm thinking there might be a seasonal component. Has this drop coincided with any particular time of year or event?

Why it matters: Seasonal patterns could indicate external factors affecting adherence. Expected answer: No clear seasonal pattern identified. Impact on approach: If seasonal, we'd focus on cyclical interventions; if not, we'd look more at systemic issues.

• Considering patient segments, I'm wondering if this drop is uniform across all demographics. Have you noticed any particular patient groups more affected than others?

Why it matters: Targeted interventions may be necessary if specific groups are disproportionately affected. Expected answer: The drop is more pronounced in elderly patients. Impact on approach: We'd tailor solutions to address barriers specific to the most affected groups.

• Thinking about recent changes, has there been any modification to the treatment regimen or delivery method in the past 6 months?

Why it matters: Changes in product or process could directly impact adherence. Expected answer: No significant changes to the treatment itself. Impact on approach: If changes occurred, we'd focus on adaptation strategies; if not, we'd look at external factors or communication issues.

• Considering market dynamics, has there been any new competitor entry or changes in insurance coverage for Prolia recently?

Why it matters: Market shifts could explain changes in patient behavior. Expected answer: No major market changes, but some minor shifts in coverage. Impact on approach: Significant market changes would require competitive analysis, while minor shifts might need targeted patient support programs.
