Akebia (AKBA) Q3 2025: Prescribing Access Expands 7x, Setting Up 2026 Inflection
Akebia’s Q3 revealed a pivotal expansion in Vafseo’s prescribing access, now reaching over 260,000 dialysis patients, up from 40,000 at the start of the year. Despite operational friction and flat sequential demand, management is positioning the company for a 2026 volume inflection as major dialysis organizations activate protocols and adherence initiatives take hold. With new clinical data and a broadened launch footprint, Akebia’s next phase will hinge on execution in large provider networks and the durability of its legacy Auryxia stream.
Summary
- Prescribing Access Surges: Vafseo’s eligible patient base increased nearly sevenfold, unlocking broader commercial runway.
- Operational Friction Remains: Flat demand and adherence hurdles signal ongoing transition pains in dialysis protocols.
- 2026 Setup Emerges: Full-year momentum depends on protocol adoption and proven physician-driven uptake at scale.
Performance Analysis
Akebia’s Q3 revenue growth was driven by both its new launch, Vafseo, and a resilient Auryxia franchise. Total revenues reached $58.8 million, with Vafseo contributing $14.3 million and Auryxia, an iron-based phosphate binder, generating $42.5 million even after losing patent exclusivity. Auryxia’s continued performance was aided by the lack of FDA-approved generics, though management cautions that future competition remains unpredictable.
Cost of goods sold (COGS) fell significantly, primarily due to the end of non-cash amortization for Auryxia, while R&D and SG&A costs rose to support the Vafseo launch and ongoing clinical programs. The company posted a small net profit, reflecting improved revenue leverage despite higher operating expenses. Vafseo’s launch metrics were mixed: More than 85 percent of prescriptions were refilled, and average dosing increased, but overall demand was flat quarter-over-quarter as new patient starts were offset by lower-than-expected adherence, particularly at US Renal Care (USRC).
- Revenue Mix Shifts: Vafseo now contributes nearly a quarter of product revenue, with Auryxia’s legacy stream still dominant but exposed to future generic entry.
- Adherence Headwinds: USRC, the lead adopter, showed lower-than-expected persistence, driving targeted protocol and education initiatives.
- Inventory and Dosing Transition: The move from home-based 150mg to in-center 300mg tablets and three-times-weekly (TIW) dosing is expected to impact near-term inventory and patient starts.
Akebia’s financials highlight a company balancing launch investment with prudent expense management, while the operational complexity of dialysis channel access is a gating factor for near-term growth.
Executive Commentary
"Having more prescriptions written in the first 41 weeks of a launch than any recent launch in dialysis suggests a very strong reception from the dialysis community. Hearing feedback from physicians about their positive experiences with Vafseo and seeing data like Dr. Chertow presented regarding the potential favorable mortality and decreased hospitalization benefits compared to ESAs gives me more reason to believe we will achieve our goal of making Vafseo standard of care for dialysis patients."
John Butler, Chief Executive Officer
"We are pleased to post another strong quarterly Auryxia result, though caution future Auryxia sales levels are challenging to predict due to the uncertainty around the timing of potential additional generic competition. Our cash position is strong... sufficient to fund our current operating plans of profitability, including the advancement of our existing pipeline."

Strategic Positioning
1. Prescribing Access as the Growth Lever
Vafseo, an oral hypoxia-inducible factor prolyl hydroxylase inhibitor (HIF-PHI) for anemia in dialysis, dramatically expanded its eligible patient pool by activating protocols at major organizations such as DaVita and Innovative Renal Care (IRC). Prescribing access now covers over 260,000 patients, up from 40,000 at the start of the year. This scale is critical, as dialysis adoption requires institutional protocols, not just individual physician demand.
2. Adherence and Protocol Optimization
Initial adherence, particularly at USRC, fell short of expectations, with many patients discontinuing after the first refill due to protocol inertia and lack of dose titration. Akebia is addressing this by retraining sales and medical teams, targeting anemia managers, and supporting the adoption of TIW dosing—expected to improve persistence as more clinics transition in Q1 2026.
3. Clinical Data as Differentiator
New win-odds analysis from the INNOVATE trials showed lower risk of death or hospitalization for Vafseo versus ESA controls, with effect size increasing in on-treatment analyses. This evidence, though not yet field-usable pending publication, is reinforcing physician enthusiasm and will become a key part of the commercial narrative. Upcoming VOCAL and VOICE studies, both leveraging TIW dosing, are positioned as future catalysts.
4. Legacy Franchise Durability
Auryxia continues to outperform expectations, benefiting from the absence of FDA-approved generics. Management is realistic that this tailwind is temporary, but the product remains a strong cash generator that funds pipeline and launch investments.
5. Channel Execution and Learning Transfer
Each dialysis organization presents unique operational hurdles, from insurance verification to protocol training. Akebia is leveraging learnings from early adopters to streamline onboarding at new centers, with the expectation that adherence and start rates will improve as protocols mature and more organizations implement best practices.
Key Considerations
This quarter’s results reflect a company at a commercial inflection, with access and operational learning now the gating factors for Vafseo’s trajectory. The next twelve months will be defined by execution in large provider networks and the ability to translate access into sustained demand.
Key Considerations:
- Access Expansion as a Precursor: The jump from 40,000 to 260,000 patients with protocol access is the most significant setup for future growth.
- Adherence Remains a Bottleneck: Educating anemia managers and optimizing TIW dosing protocols are essential to unlocking Vafseo’s revenue potential.
- Legacy Revenue at Risk: Auryxia’s resilience is a positive, but generic entry could rapidly erode this stream—investors should monitor FDA actions closely.
- Clinical Differentiation Underpins Value: New outcomes data strengthens the case for standard of care adoption, but real-world impact will require broad dissemination and label updates.
Risks
Operational complexity in the dialysis channel, including protocol adoption, insurance verification, and inventory transitions, could continue to delay volume ramp. Adherence rates remain below target, particularly at early adopters, and may take additional quarters to stabilize. Auryxia faces looming generic risk, and any FDA approval could quickly pressure cash flows that currently fund pipeline and launch activities.
Forward Outlook
For Q4, Akebia expects:
- Ordering momentum to build as DaVita and other large organizations roll out Vafseo protocols more broadly
- Short-term inventory fluctuations as clinics transition from home-based to in-center dosing
For full-year 2025, management did not provide explicit quantitative guidance, but emphasized:
- Access to nearly seven times as many eligible patients entering 2026
- Focus on operational execution and adherence improvement as primary growth drivers
Management highlighted several factors that will shape the next phase:
- Adoption of TIW dosing protocols, especially at USRC and DaVita
- Real-world impact of new clinical data and upcoming trial readouts
Takeaways
Akebia’s Q3 marks a strategic transition from launch logistics to broad commercial execution.
- Access Expansion Is the Core Growth Engine: With 260,000+ patients eligible, the foundation for future volume growth is set, but realization depends on operational throughput.
- Adherence and Protocol Learning Remain Pivotal: Addressing early drop-off and embedding TIW dosing are essential to converting access into durable revenue.
- Clinical Data and Pipeline Progress Offer Upside: Positive outcomes data and upcoming trials could accelerate physician adoption and support label expansion in coming years.
Conclusion
Akebia’s Q3 was less about immediate revenue and more about setting the stage for a 2026 inflection, as prescribing access and operational learnings accumulate. The next phase will test whether expanded protocols and improved adherence can translate into sustained commercial momentum before Auryxia’s generic headwinds arrive.
Industry Read-Through
Akebia’s experience highlights the unique commercial challenges of launching therapies in the dialysis channel, where institutional protocol adoption and operational complexity can delay uptake even with strong physician demand. Other specialty pharma companies targeting chronic care in institutional settings should note the importance of protocol-driven access, the slow pace of real-world adoption, and the critical role of adherence management. The durability of legacy cash flows in the face of generic risk remains a sector-wide theme, underscoring the need for continuous pipeline investment and operational agility.
