Averoa Secures EU Approval for Xoanacyl, a Dual-Action CKD Oral Therapy

First-in-class therapy targets iron deficiency and phosphate imbalance in CKD, offering earlier intervention and simplified treatment for European patients.

The European Commission (EC) has formally approved Averoa’s Xoanacyl (ferric citrate as a coordination complex) for marketing across the European Union, following a positive opinion from the European Medicines Agency’s Committee for Medicinal Products for Human Use that was announced in early April (1,2). The decision makes Xoanacyl the first and only approved therapy in the EU that targets both iron deficiency and elevated serum phosphorus levels, two often co-occurring complications in adults with chronic kidney disease (CKD).

Xoanacyl’s approval addresses a significant unmet need in the treatment of these two common complications of CKD that affect more than 10 million people with CKD across Europe. Patients with CKD frequently experience iron deficiency anemia and phosphate dysregulation, conditions which contribute to cardiovascular disease, vascular calcification, and increased mortality. Current therapeutic strategies often fail to address both complications effectively and at early stages of the disease, according to a news release from Averoa (1). Xoanacyl’s single oral formulation offers a dual mechanism, supplementing ferric iron while concurrently reducing phosphorus absorption.

Clinical data support dual indication for patients with CKD

Key Takeaways

·Xoanacyl receives EU approval as the first dual-action oral therapy for CKD, treating both iron deficiency and hyperphosphatemia in one formulation.

·Ferric citrate-based Xoanacyl streamlines CKD treatment regimens by combining iron repletion and phosphate reduction in a single, oral therapeutic option.

·Averoa’s regulatory strategy showcases how restructured clinical data and localized dossiers can support EU drug approval for repurposed pharmaceutical products.

The marketing authorization is supported by data from three pivotal trials originally conducted by Akebia Therapeutics, which indicated that Xoanacyl increases iron levels and lowers serum phosphorus in CKD patients (1). In late 2022, Averoa licensed exclusive rights to the therapy from Akebia for commercialization in Europe, the UK, and selected territories including Turkey and Israel.

Since acquiring the rights, Averoa has restructured the clinical dossier, aligning it with EU regulatory requirements and emphasizing the dual indication (1). The company focused on tailoring the submission to the specific needs of the European patient population, where treatment for phosphate imbalance is typically initiated only at advanced CKD stages, despite early detectability and its role in disease progression.

Oral iron therapies are often poorly tolerated or ineffective, and the under-treatment of phosphate dysregulation remains a gap in CKD management, according to Averoa (1). Xoanacyl is positioned to streamline the therapeutic approach, offering earlier and more comprehensive management of these interrelated complications.

Strategic path forward for Xoanacyl in European markets

“This approval represents a major strategic milestone for our company, opening the door to one of Europe’s most important healthcare markets, where tens of millions of people are living with chronic kidney disease,” said Luc-André Granier, president and medical director at Averoa (1). “It underscores Averoa’s ability to translate scientific excellence into real-world patient impact. We are deeply grateful to all our partners who made this milestone possible, and we are proud to bring this novel therapy to CKD patients across Europe… We look forward to working with strategic partners to drive the commercial potential of Xoanacyl across Europe.”

The company has also submitted a marketing authorization application to the UK’s Medicines and Healthcare products Regulatory Agency under the International Recognition Procedure, signaling its intention to broaden access to the therapy beyond the EU (1).

The widespread burden of chronic kidney disease

CKD is characterized by the progressive loss of kidney function and is one of the ten leading causes of death in developed countries (1). In Europe, prevalence estimates range from 3% to 17%. CKD arises from a wide range of causes, including hypertension, diabetes, glomerulonephritis, polycystic kidney disease, and other hereditary or environmental factors. The condition often leads to complications, such as iron deficiency anemia and mineral and bone disorders, both of which contribute to increased fibroblast growth factor 23 (FGF23) and cardiovascular risk.

Without effective early treatment, CKD can progress to end-stage kidney failure, requiring dialysis or transplantation. The dual therapeutic action of Xoanacyl offers a more integrated pharmacological approach to slowing this progression by addressing two key metabolic imbalances concurrently.

Xoanacyl has already been commercialized under different brand names in other regions, including Auryxia in the United States (by Akebia Therapeutics), Riona in Japan (by Japan Tobacco Inc.), and Nephoxil in Taiwan and South Korea.
