Vadadustat

Continued Vafseo® (vadadustat) growth with Q2 2025 net product revenues increasing to $13.3 million; Total Q2 2025 net product revenues increased to $60.5 million DaVita physicians are expected to begin treating patients with Vafseo in August 2025 as part of an operational pilot at 100+ DaVita dialysis clinics Patient enrollment completed in VOICE, a collaborative clinical trial of Vafseo conducted by USRC Akebia to host Conference Call at 8:00 a.m. ET on Thursday, August 7, 2025 CAMBRIDGE, Mass., Aug. 07, 2025 (GLOBE NEWSWIRE) -- Akebia Therapeutics®, Inc. (Nasdaq: AKBA), a biopharmaceutical company with the purpose to better the lives of people impacted by kidney disease, today reported financial results for the second quarter ended June 30, 2025 and recent business highlights. “Vafseo® (vadadustat) U.S. product launch momentum builds as we continued to add new prescribers, increase volume with existing writers, and importantly, progress efforts to further expand patient access to the therapy,” said John P. Butler, Chief Executive Officer of Akebia. “We are working to increase utilization at mid-sized dialysis organizations, and we expect by September, both Dialysis Clinics, Inc. (DCI) and Innovative Renal Care (IRC), the fourth and fifth largest dialysis organizations, will have operationalized protocols to simplify and expand Vafseo prescribing. Additionally, we are pleased that DaVita has begun ordering Vafseo to support an operational pilot in Q3, which we expect to lead to the opportunity for broad prescribing before year end. I am also excited about the progress we have made executing on our post-marketing development strategy, which is critical to our ultimate goal of making Vafseo the standard of care for the treatment of anemia in patients with chronic kidney disease (CKD).” Vafseo U.S. Commercial Updates: Vafseo net product revenue in Q2 2025 totaled $13.3 million. Prescription demand grew by approximately 55% over Q1 2025 and customer inventory weeks on hand remained approximately flat. During the quarter, more than 725 prescribers wrote a prescription for Vafseo and prescribers, on average, wrote more than 13 prescriptions.More than 80% of prescriptions in Q2 were refill prescriptions. The average dose of refills increased by approximately 25%.By the end of Q3, we expect dialysis organizations will have operationalized protocols enabling Vafseo prescribing access to more than 75,000 patients, an increase from about 40,000 patients at the end of Q2.DaVita, a leading dialysis organization serving more than 200,000 patients, is expected to enable prescribing Vafseo to patients in an operational pilot this month. In July, DaVita placed an order to begin to supply the pilot across more than 100 clinics. The purpose of this pilot study is to ensure that prescribers can write Vafseo and efficiently deliver the drug to dialysis patients. Additional Key Business Updates: U.S. Renal Care (USRC) completed enrollment in VOICE, a collaborative clinical trial of Vafseo designed to measure non-inferiority of Vafseo versus standard-of-care erythropoietin stimulating agents (ESAs) using hierarchical endpoints of all-cause mortality and all-cause hospitalization. USRC enrolled 2,116 patients and top line data are expected in early 2027.Akebia initiated the VOCAL trial to evaluate the efficacy and safety of three times per week (TIW) dosing of vadadustat compared to standard of care ESAs in patients with anemia of CKD receiving in-center hemodialysis. The trial is expected to enroll approximately 350 patients across 18 DaVita hemodialysis clinics. The trial will include a sub-study of approximately 28 patients to study the impact of Vafseo on red blood cell phenotypes (e.g., deformability, resistance to oxidative stress, metabolomics) compared to ESA treatment.Akebia is working towards its goal to initiate VALOR, a Phase 3 clinical trial to study the use of vadadustat for treating anemia in late-stage CKD patients who are not on dialysis by the end of this year. The company has requested a Type-C meeting with the U.S. Food and Drug Administration.Auryxia® (ferric citrate) net product revenue in Q2 2025 totaled $47.2 million. Though loss of exclusivity occurred on March 20, 2025, to date no Abbreviated New Drug Application has been approved for Auryxia, and there is only one authorized generic for Auryxia sold by Akebia’s distributor. Financial Results Revenues: Total revenues increased to $62.5 million in the second quarter of 2025 compared to $43.6 million in the second quarter of 2024, driven by sales of Vafseo, which was launched in the U.S. in January 2025, and an increase in Auryxia sales. Vafseo net product revenues were $13.3 million in the second quarter of 2025.Auryxia net product revenues were $47.2 million in the second quarter of 2025 as compared to $41.2 million in the second quarter of 2024.License, collaboration and other revenues were $2.0 million in the second quarter of 2025 as compared to $2.4 million in the second quarter of 2024. Cost of Goods Sold: Cost of goods sold was $9.9 million in the second quarter of 2025 as compared to $17.0 million in the second quarter of 2024. Akebia carried a non-cash intangible amortization charge of $9.0 million per quarter through the fourth quarter of 2024. Of note, Vafseo-related cost of goods sold in the quarter was derived from pre-launch inventory, which does not include the full cost of manufacturing as a portion of those inventory-related expenses were recorded as research and development expenses in the period incurred prior to Vafseo’s approval in the U.S.Research & Development Expenses: Research and development expenses were $11.0 million in the second quarter of 2025 as compared to $7.6 million in the second quarter of 2024. The increase was primarily driven by increased clinical trial activities related to Vafseo as well as our other programs.Selling, General & Administrative Expenses: Selling, general and administrative expenses were $26.6 million in the second quarter of 2025 as compared to $26.9 million in the second quarter of 2024.Net Income (Loss): Net income was $0.2 million in the second quarter of 2025 compared to a net loss of $8.6 million in the second quarter of 2024. The increase in net income was driven by the increase in net product revenues, which was partially offset by $7.0 million in non-cash expense related to the change in fair value of our warrant liability, as well as $5.4 million in non-cash interest expense related to the settlement royalty liability in connection with the Vifor Termination and Settlement Agreement that Akebia signed in July 2024. Cash Position: Cash and cash equivalents as of June 30, 2025 were approximately $137.3 million. Akebia believes it is financed to achieve profitability based on its current operating plan, which includes pursuing label expansion for Vafseo and advancing other existing programs.

About Vafseo® (vadadustat) tablets Vafseo® (vadadustat) tablets is a once-daily oral hypoxia-inducible factor prolyl hydroxylase inhibitor that activates the physiologic response to hypoxia to stimulate endogenous production of erythropoietin, increasing hemoglobin and red blood cell production to manage anemia. Vafseo is approved for use in 37 countries. INDICATION VAFSEO is indicated for the treatment of anemia due to chronic kidney disease (CKD) in adults who have been receiving dialysis for at least three months. Limitations of Use VAFSEO has not been shown to improve quality of life, fatigue, or patient well-being.VAFSEO is not indicated for use: As a substitute for red blood cell transfusions in patients who require immediate correction of anemia.In patients with anemia due to CKD not on dialysis. IMPORTANT SAFETY INFORMATION about VAFSEO (vadadustat) tablets WARNING: INCREASED RISK OF DEATH, MYOCARDIAL INFARCTION, STROKE, VENOUS THROMBOEMBOLISM, and THROMBOSIS OF VASCULAR ACCESS. VAFSEO increases the risk of thrombotic vascular events, including major adverse cardiovascular events (MACE). Targeting a hemoglobin level greater than 11 g/dL is expected to further increase the risk of death and arterial and venous thrombotic events, as occurs with erythropoietin stimulating agents (ESAs), which also increase erythropoietin levels. No trial has identified a hemoglobin target level, dose of VAFSEO, or dosing strategy that does not increase these risks. Use the lowest dose of VAFSEO sufficient to reduce the need for red blood cell transfusions. CONTRAINDICATIONS Known hypersensitivity to VAFSEO or any of its componentsUncontrolled hypertension WARNINGS AND PRECAUTIONS Increased Risk of Death, Myocardial Infarction (MI), Stroke, Venous Thromboembolism, and Thrombosis of Vascular AccessA rise in hemoglobin (Hb) levels greater than 1 g/dL over 2 weeks can increase these risks. Avoid in patients with a history of MI, cerebrovascular event, or acute coronary syndrome within the 3 months prior to starting VAFSEO. Targeting a Hb level of greater than 11 g/dL is expected to further increase the risk of death and arterial and venous thrombotic events. Use the lowest effective dose to reduce the need for red blood cell (RBC) transfusions. Adhere to dosing and Hb monitoring recommendations to avoid excessive erythropoiesis. HepatotoxicityHepatocellular injury attributed to VAFSEO was reported in less than 1% of patients, including one severe case with jaundice. Elevated serum ALT, AST, and bilirubin levels were observed in 1.8%, 1.8%, and 0.3% of CKD patients treated with VAFSEO, respectively. Measure ALT, AST, and bilirubin before treatment and monthly for the first 6 months, then as clinically indicated. Discontinue VAFSEO if ALT or AST is persistently elevated or accompanied by elevated bilirubin. Not recommended in patients with cirrhosis or active, acute liver disease. HypertensionWorsening of hypertension was reported in 14% of VAFSEO and 17% of darbepoetin alfa patients. Serious worsening of hypertension was reported in 2.7% of VAFSEO and 3% of darbepoetin alfa patients. Cases of hypertensive crisis, including hypertensive encephalopathy and seizures, have also been reported in patients receiving VAFSEO. Monitor blood pressure. Adjust anti-hypertensive therapy as needed. SeizuresSeizures occurred in 1.6% of VAFSEO and 1.6% of darbepoetin alfa patients. Monitor for new-onset seizures, premonitory symptoms, or change in seizure frequency. Gastrointestinal (GI) ErosionGastric or esophageal erosions occurred in 6.4% of VAFSEO and 5.3% of darbepoetin alfa patients. Serious GI erosions, including GI bleeding and the need for RBC transfusions, were reported in 3.4% of VAFSEO and 3.3% of darbepoetin alfa patients. Consider this risk in patients at increased risk of GI erosion. Advise patients about signs of erosions and GI bleeding and urge them to seek prompt medical care if present. Serious Adverse Reactions in Patients with Anemia Due to CKD and Not on DialysisThe safety of VAFSEO has not been established for the treatment of anemia due to CKD in adults not on dialysis and its use is not recommended in this setting. In large clinical trials in adults with anemia of CKD who were not on dialysis, an increased risk of mortality, stroke, MI, serious acute kidney injury, serious hepatic injury, and serious GI erosions was observed in patients treated with VAFSEO compared to darbepoetin alfa. MalignancyVAFSEO has not been studied and is not recommended in patients with active malignancies. Malignancies were observed in 2.2% of VAFSEO and 3.0% of darbepoetin alfa patients. No evidence of increased carcinogenicity was observed in animal studies. ADVERSE REACTIONS The most common adverse reactions (occurring at ≥ 10%) were hypertension and diarrhea. DRUG INTERACTIONS Iron supplements and iron-containing phosphate binders: Administer VAFSEO at least 1 hour before products containing iron.Non-iron-containing phosphate binders: Administer VAFSEO at least 1 hour before or 2 hours after non-iron-containing phosphate binders.BCRP substrates: Monitor for signs of substrate adverse reactions and consider dose reduction.Statins: Monitor for statin-related adverse reactions. Limit the daily dose of simvastatin to 20 mg and rosuvastatin to 5 mg. USE IN SPECIFIC POPULATIONS Pregnancy: May cause fetal harm.Lactation: Breastfeeding not recommended until two days after the final dose.Hepatic Impairment: Not recommended in patients with cirrhosis or active, acute liver disease.

VOCAL, an open-label active-controlled study, is being conducted at DaVita dialysis clinics to evaluate benefits of treating patients with Vafseo three times a weekCAMBRIDGE, Mass., Aug. 04, 2025 (GLOBE NEWSWIRE) -- Akebia Therapeutics®, Inc. (Nasdaq: AKBA), a biopharmaceutical company with the purpose to better the lives of people impacted by kidney disease, today announced the initiation of a post-marketing study to identify additional potential benefits of Vafseo® (vadadustat). The VOCAL trial, conducted within DaVita clinics, aims to generate data to evaluate the efficacy and safety of three times per week (TIW) dosing of vadadustat compared to standard of care erythropoiesis-stimulating agents (ESA) in patients with anemia of CKD receiving in-center hemodialysis. “Our team and partners within the dialysis community share a commitment to improving patient care,” said Steven K. Burke, M.D., Chief Medical Officer of Akebia. “The VOCAL trial, conducted within DaVita clinics, enables us to continue building the body of evidence on the effectiveness of Vafseo when dosed three times a week as well as to understand the potential additional benefits of Vafseo treatment for anemia in CKD patients.” The VOCAL trial is expected to enroll approximately 350 patients across 18 DaVita hemodialysis clinics. This open-label trial will employ 1:1 randomization. Patients will participate in the study for up to 33 weeks including screening, treatment and safety follow-up. The primary endpoint of the study is change in hemoglobin, and secondary endpoints include number of patients reporting treatment-emergent serious adverse events, proportion of patients within target hemoglobin range and proportion of patients receiving RBC transfusions, in each case, compared to ESA treatment. The VOCAL trial will also include a sub-study of approximately 28 patients from three clinics who will have blood samples collected and analyzed over the course of a 6-month treatment period. One major factor contributing to the anemia of CKD patients is reduced red blood cell (RBC) quality. Working in consultation with Vitalant Research Institute, the intent of the sub-study is to better understand the impact of Vafseo on RBC phenotypes (e.g. deformability, resistance to oxidative stress, metabolomics) compared to ESA treatment. “DaVita is committed to be at the forefront of innovation by evaluating novel treatments that improve clinical practice and benefit patient care,” said Dr. Steven Brunelli, MD, MSCE, Vice President and Medical Director of DaVita Outcomes Research. “The VOCAL trial evaluates Vafseo as a potential new standard of care in a real-world setting and explores additional potential benefits for patients.” Vafseo was approved by the U.S. Food and Drug Administration in March 2024 for the treatment of anemia due to chronic kidney disease (CKD) in adults who have been receiving dialysis for at least three months, and the product became available in the U.S. in January 2025.
