The Company believes AAV‑hAQP1 represents a significant commercial opportunity as a potential first‑in‑class, disease‑modifying therapy for late, moderate‑to‑severe radiation‑induced xerostomia (RIX), a severe, lifelong condition with no effective treatments. Persistent RIX affects an estimated 165,000 patients in the United States and approximately 435,000 patients globally, with ~48,000 new cases globally across major markets. Market research incorporating our three‑year durability data demonstrated extremely strong physician enthusiasm, with approximately 78% clinician‑stated preference translating to ~52% projected usage after adjustment, alongside favorable payor perceptions and an estimated ~90% U.S. market access coverage. Based on primary market research commissioned by the Company, the Company estimates peak global annual revenue potential of approximately $3.7 billion, with a steady state estimate of approximately $3.2 billion annually in the late 2030s. In the U.S. alone, this translates to estimated peak annual revenue of approximately $2.0 billion, with a steady state of approximately $1.8 billion annually in the late 2030s. These estimates are supported by a concentrated U.S. treatment landscape enabling efficient access to a majority of eligible patients through a focused set of major treatment centers.
