Akebia Therapeutics, fresh off the FDA approval of its anemia drug Vafseo (vadadustat) for dialysis patients, is abuzz with launch preparations. But buried within the celebratory Q1 2024 earnings call transcript lies a subtle yet potentially game-changing strategy that seems to have slipped past most analysts' radar: a quiet focus on expanding Vafseo's reach to Chronic Kidney Disease (CKD) patients *not* on dialysis.

While the immediate focus is understandably on capitalizing on the $1 billion dialysis market, Akebia's CEO, John Butler, repeatedly emphasized the potential of Vafseo for non-dialysis CKD patients, particularly those with a glomerular filtration rate (GFR) below 15. This segment, representing a large swathe of untreated patients with heightened mortality risk, is being positioned as a crucial long-term value driver for Vafseo, impacting even the initial TDAPA pricing strategy.

This seemingly innocuous detail hints at a much larger play. Akebia is betting on a future where Vafseo isn't just another anemia drug in the crowded dialysis space but a cornerstone therapy for a vast, currently neglected patient population. The company is essentially crafting a two-pronged attack: secure a strong foothold in the dialysis market through TDAPA and simultaneously lay the groundwork for a potentially much larger non-dialysis expansion.

Why This Strategy Matters

Firstly, it reveals a forward-thinking strategy that extends beyond the immediate lure of TDAPA reimbursements. Akebia is acutely aware of the post-TDAPA landscape, where pricing pressure is inevitable. Securing approval for non-dialysis patients would provide a vital second revenue stream, mitigating potential losses from the dialysis market once TDAPA concludes.

Secondly, the emphasis on NDD patients in the context of WACC pricing suggests Akebia is aiming for a premium price point for Vafseo, justifying it through the drug's potential value across a broader patient population. This is a bold move, considering the existing competition in the dialysis market and downward pressure on ESA pricing.

The Numbers Tell the Story

The lack of effective treatment options for non-dialysis CKD patients makes Vafseo a particularly attractive proposition. Butler highlighted the grim reality: over 70% of NDD patients with GFR below 15 are currently untreated, suffering from uncontrolled anemia and facing higher mortality rates. Vafseo, as a once-daily oral medication, offers a convenient and potentially life-saving alternative, potentially driving rapid adoption in this underserved market.

Navigating the Regulatory Path

Akebia's gamble hinges on successfully navigating the regulatory path for NDD approval. The company is planning to engage the FDA this year, proposing a focused subpopulation study to bolster its existing data. This strategic move allows Akebia to leverage its existing clinical trial infrastructure, potentially accelerating the approval timeline and minimizing costs.

Potential Impact of Akebia's Strategy

While a new clinical trial carries inherent risks, the potential rewards are substantial. A successful NDD approval would not only solidify Vafseo's market dominance but also position Akebia as a key player in the larger CKD landscape, potentially attracting partnerships and expanding its pipeline beyond anemia.

Vafseo vs Auryxia Revenue Projections (Hypothetical)

Akebia's subtle strategy, masked by the Vafseo launch fanfare, reveals a shrewd understanding of the evolving market dynamics and a long-term vision that extends beyond TDAPA. By targeting an untapped patient population with immense unmet needs, Akebia is quietly positioning Vafseo for a level of success that could surpass even the most optimistic dialysis market projections. This silent gamble, if successful, could redefine the CKD landscape and catapult Akebia to the forefront of renal disease treatment.
