David Risinger's questions to Theravance Biopharma (TBPH) leadership • Q2 2025
Question
David Risinger of Leerink Partners asked if YUPELRI's operating leverage would continue and questioned how the longer endpoint duration in the Ampreloxetine trial might impact results.
Answer
CFO Aziz Sawaf clarified that while YUPELRI's profit margin will continue to expand with sales growth, the significant gap between collaboration revenue growth and net sales growth should not be expected to persist. Head of Development Aine Miller explained the 8-week endpoint is designed to demonstrate durability, a key differentiator. CEO Rick Winningham added that Ampreloxetine's mechanism as a reuptake inhibitor, not an agonist, makes tachyphylaxis less likely.
