Akebia regains full rights to sell Vafseo® (vadadustat) Tablets in the U.S. following the execution of a royalty-based termination agreement with CSL Vifor to simplify operational execution and improve economics Announced Vafseo WAC pricing of $1,278 for a 30-day supply Submitted TDAPA application for Vafseo in June 2024 and expects designation on January 1, 2025 Akebia to host investor conference call at 8:00 a.m. ET on July 11, 2024 CAMBRIDGE, Mass., July 11, 2024 /PRNewswire/ -- Akebia Therapeutics®, Inc. (Nasdaq: AKBA), a biopharmaceutical company with the purpose to better the lives of people impacted by kidney disease, today announced key updates pertaining to the commercial launch of Vafseo® (vadadustat) Tablets. Akebia will host an investor conference call at 8:00 a.m. ET on Thursday, July 11, 2024. "Since Vafseo approval in late March, our team has worked diligently on commercial launch activities to drive prescriber demand with the goal to optimize Vafseo's revenue ramp during the two-year Transitional Drug Add-on Payment Adjustment (TDAPA) period expected to begin in January 2025 and beyond," said John P. Butler, Chief Executive Officer of Akebia. "This is a multi-faceted endeavor, and today I am excited to share progress made on multiple fronts. First, we have established a wholesale acquisition cost (WAC) that reflects the value of Vafseo in both the dialysis and, if approved, non-dialysis populations. Additionally, contracting effectively with dialysis organizations is critical to a successful launch. To help facilitate the contracting process, as well as simplify the operational management of the product, we have agreed with CSL Vifor to terminate the existing license, resulting in Akebia regaining rights to sell Vafseo to Fresenius Kidney Care dialysis centers and specific other third-party dialysis organizations in the U.S. In addition, we have made significant progress in contract discussions with dialysis organizations for both Auryxia and Vafseo. Having now executed this agreement with CSL Vifor, we can accelerate contracting discussions and expect to have contracts in place with dialysis providers treating the vast majority of eligible Vafseo patients before January 2025. I want to thank our colleagues at CSL Vifor for their collaboration over the past years, and I look forward to continuing to work with them under this new relationship." Vafseo Commercial Launch Updates: CSL Vifor Agreement: Akebia and CSL Vifor have entered into a termination agreement of the license agreement providing for the payment of royalties by Akebia to CSL Vifor on Vafseo U.S. net product sales. As a result, Akebia regained full rights to sell Vafseo in the U.S. and is able to contract directly with all dialysis organizations effective immediately. Akebia believes its existing and well-established renal sales and medical affairs teams are equipped to drive prescriber demand and enable dialysis organization contracting. Under the terms of the agreement, CSL Vifor is entitled to quarterly tiered royalty payments ranging from a high single-digit percentage on annual net sales up to $450 million to a mid-single digit percentage on annual net sales above $450 million. Akebia has the opportunity to buy down the royalty agreement beginning on July 1, 2027 with a one-time payment to CSL Vifor, which would decrease the royalty payments to a mid-single digit percentage of Akebia's annual net sales of Vafseo up to $450 million and eliminate the royalty payment on annual net sales above $450 million. TDAPA Submission: In June, Akebia submitted its TDAPA application. Akebia expects to have Healthcare Common Procedure Coding System (HCPCS) codes assigned in October 2024 and full TDAPA designation by January 1, 2025. Vafseo Pricing: Vafseo WAC has been set at $1,278 for a 30-day supply at the minimum starting dose, or approximately $15,500 per year. The entire dialysis business will be a contracted business, offering an off-invoice discount as well as volume tier discounts off this WAC price. The potential label expansion into non-dialysis patients was an important factor in determining the WAC pricing for Vafseo.

Akebia to host conference call at 8:00 a.m. ET on May 9 Vafseo® (vadadustat) tablets FDA approved on March 27, 2024 Vafseo launch activities underway with availability expected in January 2025 Auryxia® (ferric citrate) net product revenues were $31.0 million for the first quarter 2024, Akebia expects 2024 Auryxia net product revenue growth versus 2023 CAMBRIDGE, Mass., May 9, 2024 /PRNewswire/ -- 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 first quarter ended March 31, 2024. Akebia is launching Vafseo® (vadadustat) tablets, recently approved by the U.S. Food and Drug Administration (FDA) for the treatment of anemia due to chronic kidney disease (CKD) in adults who have been receiving dialysis for at least three months, which will be available in January 2025. "The recent FDA approval of Vafseo represents a transformational milestone for Akebia as we initiate launch activities that we believe will enable widespread access and rapid adoption when Vafseo is available in January 2025," said John P. Butler, Chief Executive Officer of Akebia. "Upon FDA approval of Vafseo, we initiated work to drive demand from potential prescribers and to contract with dialysis providers. We are progressing plans for generating clinical data to identify additional areas of potential benefit to patients as we remain committed to the kidney community. We also expect to engage with the FDA on label expansion opportunities for Vafseo by the end of this year." Recent Business Highlights Akebia plans to submit its application for Transitional Drug Add-on Payment Adjustment (TDAPA) for Vafseo in June. Akebia expects the application to be accepted in July 2024 and expects TDAPA designation in January 2025. In March, Akebia presented posters at the 2024 Annual Dialysis Conference on the cardiovascular safety of vadadustat in patients new to dialysis with CKD-related anemia and the safety and efficacy of vadadustat in the treatment of anemia in U.S. patients with CKD. In April, Akebia's licensee Averoa, a biopharmaceutical company, submitted a marketing authorization application to the European Medicines Agency for Ferric Citrate Coordination Complex, and, if approved, Averoa will make the product available to patients in Europe. In April, Akebia drew down the second tranche of its $55.0 million BlackRock debt facility and received net proceeds of $7.5 million. Ten million dollars of borrowing capacity remains available under the debt facility until December 31, 2024, subject to the conditions in the loan agreement. In May, Akebia signed an amendment to its License Agreement with Vifor International Ltd. (Vifor) to modify the method of repayment of its working capital fund through tiered royalties based upon Akebia's sales of Vafseo, significantly simplifying the repayment terms. Akebia reported first quarter 2024 Auryxia® (ferric citrate) net product revenues of $31.0 million. Akebia reaffirms that it expects Auryxia net product revenue growth in 2024 versus 2023. The Centers for Medicare and Medicaid Services released guidance on incorporating phosphate binders, including Auryxia, into the dialysis bundle in January 2025. Akebia is accelerating contracting discussions with dialysis organizations with a goal to ensure broad access to Auryxia. "With continued revenue contributions from Auryxia, revenue from Vafseo beginning in 2025, and our current cash balance, we believe we have sufficient cash to support operations for at least the next two years while investing in the Vafseo launch," Mr. Butler added. Financial Results Revenues: Total revenues were $32.6 million for the first quarter of 2024 compared to $40.0 million for the first quarter of 2023. Net product revenues were $31.0 million for the first quarter of 2024 compared to $34.7 million for the first quarter of 2023. License, collaboration and other revenues were $1.6 million for the first quarter of 2024 compared to $5.3 million for the first quarter of 2023. COGS: Cost of goods sold was $11.6 million for the first quarter of 2024 compared to $20.2 million for the first quarter of 2023. Akebia continues to carry a non-cash intangible amortization charge of $9.0 million per quarter through the fourth quarter of 2024. R&D Expenses: Research and development expenses were $9.7 million for the first quarter of 2024 compared to $19.7 million for the first quarter of 2023. SG&A Expenses: Selling, general and administrative expenses were $25.4 million for the first quarter of 2024 compared to $25.1 million for the first quarter of 2023. Net Income / Loss: Net loss was $18.0 million for the first quarter of 2024 compared to a net loss of $26.9 million for the first quarter of 2023. Cash Position: Cash and cash equivalents as of March 31, 2024, were approximately $42.0 million. Akebia expects its existing cash resources and cash from operations will be sufficient to fund its current operating plan, including a U.S. Vafseo launch, for at least the next two years.

Akebia was founded in 2007 and is headquartered in Cambridge, Massachusetts. For more information, please visit our website at , which does not form a part of this release. 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 CONTRAINDICATIONS Known hypersensitivity to VAFSEO or any of its components Uncontrolled hypertension WARNINGS AND PRECAUTIONS Increased Risk of Death, Myocardial Infarction, Stroke, Venous Thromboembolism, and Thrombosis of Vascular Access A rise in hemoglobin (Hb) levels greater than 1 g/dL over 2 weeks can increase these risks. Avoid use in patients with a history of myocardial infarction, cerebrovascular event, or acute coronary syndrome within the 3 months prior to starting VAFSEO. Targeting a Hb level of greater than 11g/dL is expected to further increase the risk of death and arterial and venous thrombotic events, as occurs with ESAs, which also increase erythropoietin levels. No specific Hb target level, dose of VAFSEO, or dosing strategy has been identified to avoid these risks. Use the lowest effective dose and adhere to dosing and Hb monitoring recommendations to avoid excessive erythropoiesis. Advise patients to seek immediate medical attention if they develop signs or symptoms of myocardial infarction, stroke, venous thromboembolism, or thrombosis of vascular access. Evaluate and manage promptly if these occur. Hepatotoxicity Hepatocellular injury attributed to VAFSEO was reported in less than 1% of patients, including one severe case with jaundice. All events were asymptomatic and resolved after discontinuation of VAFSEO. The time to onset was generally within the first 3 months of treatment. 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. Hypertension Worsening of hypertension was reported in 14% (9.4 per 100 person-years [PY]) of patients receiving VAFSEO and 17% (11.8 per 100 PY) of patients receiving darbepoetin alfa. Serious worsening of hypertension was reported in 2.7% (1.7 per 100 PY) of patients receiving VAFSEO and 3% (1.8 per 100 PY) of patients receiving darbepoetin alfa. 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. Seizures Seizures occurred in 1.6% (1.0 per 100 PY) of patients who received VAFSEO and 1.6% (1.0 per 100 PY) of patients who received darbepoetin alfa. Following initiation of VAFSEO, monitor patients closely for premonitory neurologic symptoms. Monitor for new-onset seizures, premonitory symptoms, or change in seizure frequency. Gastrointestinal Erosion Gastric or esophageal erosions occurred in 6.4% (4.0 per 100 PY) of patients receiving VAFSEO and 5.3% (3.3 per 100 PY) of darbepoetin alfa-treated patients. Serious gastrointestinal (GI) erosions, including GI bleeding and the need for red blood cell transfusions were reported in 3.4% (2.1 per 100 PY) and 3.3% (2.0 per 100 PY) of those receiving VAFSEO and darbepoetin alfa, respectively. Consider the risk of GI erosion in high-risk patients, including those with a history of GI erosion, peptic ulcer disease, and tobacco or alcohol use. Advise patients of the signs and symptoms of erosions and GI bleeding and urge them to seek prompt medical care if present. Serious Adverse Reactions in Patients with Anemia Due to Chronic Kidney Disease and Not on Dialysis The 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, myocardial infarction, serious acute kidney injury, serious hepatic injury, and serious GI erosions was observed in patients treated with VAFSEO compared to darbepoetin alfa. Malignancy VAFSEO has not been studied and is not recommended in patients with active malignancies. Malignancies were observed in 2.2% (1.3 per 100 PY) of patients treated with VAFSEO and 3.0% (1.8 per 100 PY) of patients treated with darbepoetin alfa. 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 (20 mg) and rosuvastatin (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 for use in patients with cirrhosis or active, acute liver disease. Please note that this information is not comprehensive. Please click here for the Full Prescribing Information, including BOXED WARNING and Medication Guide. IMPORTANT U.S. SAFETY INFORMATION FOR AURYXIA (ferric citrate) CONTRAINDICATION AURYXIA (ferric citrate) is contraindicated in patients with iron overload syndromes, e.g., hemochromatosis. WARNINGS AND PRECAUTIONS Iron Overload: Increases in serum ferritin and transferrin saturation (TSAT) were observed in clinical trials with AURYXIA in patients with chronic kidney disease (CKD) on dialysis treated for hyperphosphatemia, which may lead to excessive elevations in iron stores. Assess iron parameters prior to initiating AURYXIA and monitor while on therapy. Patients receiving concomitant intravenous (IV) iron may require a reduction in dose or discontinuation of IV iron therapy. Risk of Overdosage in Children Due to Accidental Ingestion: Accidental ingestion and resulting overdose of iron-containing products is a leading cause of fatal poisoning in children under 6 years of age. Advise patients of the risks to children and to keep AURYXIA out of the reach of children. ADVERSE REACTIONS Most common adverse reactions with AURYXIA were: Hyperphosphatemia in CKD on Dialysis: Diarrhea (21%), discolored feces (19%), nausea (11%), constipation (8%), vomiting (7%) and cough (6%). Iron Deficiency Anemia in CKD Not on Dialysis: Discolored feces (22%), diarrhea (21%), constipation (18%), nausea (10%), abdominal pain (5%) and hyperkalemia (5%). SPECIFIC POPULATIONS Pregnancy and Lactation: There are no available data on AURYXIA use in pregnant women to inform a drug-associated risk of major birth defects and miscarriage. However, an overdose of iron in pregnant women may carry a risk for spontaneous abortion, gestational diabetes and fetal malformation. Data from rat studies have shown the transfer of iron into milk, hence, there is a possibility of infant exposure when AURYXIA is administered to a nursing woman. To report suspected adverse reactions, contact Akebia Therapeutics at 1-844-445-3799. Please click to see the full Prescribing Information for AURYXIA.
