Vafseo Launch and Market Opportunity - Vafseo (vadadustat) has launched as a treatment for anemia due to chronic kidney disease (CKD) in adult patients on dialysis[8] - The U S market opportunity for Vafseo in the dialysis patient population is approximately $1 billion[8] - Akebia is pursuing label expansion of Vafseo for the late-stage non-dialysis CKD population, representing a multi-billion-dollar U S market opportunity[8] - Contracts are secured covering nearly 100% of U S dialysis patients for Vafseo[12, 20] Clinical and Patient Considerations - Current standard of care for dialysis patients (ESAs) has remained unchanged for 30 years, with nearly 25% of patients falling below target hemoglobin levels[13] - Approximately 20% of patients on dialysis are ESA hyporesponders, leading to higher hospitalization and mortality rates[13] - Market research indicates that over 2 out of 3 nephrologists identify an unmet need for anemia treatment in CKD, particularly for oral options and ESA-resistant patients[14] VOICE Trial and Label Expansion - The VOICE trial, with over 650 subjects enrolled as of January 10, 2025, is designed to demonstrate non-inferiority for all-cause mortality and superiority for a 10% reduction in all-cause hospitalization[23, 24] - A Phase 3 clinical trial for Vafseo in late-stage CKD patients not on dialysis is planned to begin in mid-2025[8, 46] Non-Dialysis Market - In patients with pre-hemodialysis Hb <9 0 g/dL (n=4855), 73 4% did not receive ESA pre-HD[26] - The U S non-dialysis market opportunity for anemia treatment is approximately $1 billion, driven by predominantly private and unbundled government payment structures[40, 41] HIF-based Pipeline - Akebia is advancing a HIF-based pipeline targeting high unmet needs, including ROP (rare disease) with a ~$1 5B+ U S market opportunity and ~30K patients[50]
