FREMONT, Calif. and WALTHAM, Mass., March 8, 2021 /PRNewswire/ -- Ardelyx, Inc. (Nasdaq: ARDX), a biopharmaceutical company focused on developing innovative first-in-class medicines to improve treatment for people with kidney and cardiorenal diseases, today reported business highlights and financial results for the fourth quarter and full year ended December 31, 2020.
"The stage is set for an exciting year for Ardelyx in 2021" said Mike Raab, president and chief executive officer at Ardelyx. "With our PDUFA date of April 29 rapidly approaching, we are well positioned and well prepared to commercialize tenapanor upon potential FDA approval of the first and only phosphate absorption inhibitor for the control of serum phosphorus. In addition, we continue to make great progress in developing our pipeline of novel therapeutics and in building the organization for success. Our dedication and hard work over the years, particularly in 2020, have led to major advances in our development pipeline that we believe will offer differentiated benefits to patients."
Key Recent and 2020 Accomplishments:
Submitted a New Drug Application (NDA) for tenapanor for the control of serum phosphorus in adult patients with chronic kidney disease (CKD) on dialysis and received acceptance from FDA and a Prescription Drug User Fee Act (PDUFA) date of April 29, 2021.
Increased education and visibility on clinical data for tenapanor with:
Five posters at ASN Kidney Week 2020, three of which covered the company's AMPLIFY, PHREEDOM, and BLOCK Phase 3 clinical trial results, with the other two posters highlighting data from Phase 2 clinical trials evaluating the efficacy and safety of tenapanor in patients on hemodialysis conducted by the company's partner for tenapanor in Japan, Kyowa Kirin Co., Ltd (KKC).
Data analysis reported in June 2020 from ongoing NORMALIZE 18-month extension study showing that the use of tenapanor alone or in combination with sevelamer carbonate produced a significant phosphorus-lowering effect, with up to 47.4% of the 171 patients in the interim analysis achieving a normal serum phosphorus level, and of those, the majority were on tenapanor alone or tenapanor with low dose sevelamer of three or fewer sevelamer tablets per day.
Ardelyx's collaboration partner in Japan, KKC, presented data at the European Renal Association-European Dialysis and Transplant Association annual meeting (ERA-EDTA 2020) from a Phase 2 study designed to evaluate if patients with hyperphosphatemia undergoing hemodialysis, who were switched to tenapanor, could achieve at least a 30% decrease in mean pill burden while maintaining their serum phosphorus level. The results demonstrated that tenapanor enabled a significant reduction in overall pill burden (mean reduction in phosphate binder pill usage by 80%), while maintaining serum phosphorus levels (mean serum phosphorus levels 5.2 mg/dL at baseline and 4.7 mg/dL at week 26).
Presented safety and pharmacodynamics data from a Phase 1 clinical study with RDX013, noting that the results of the Phase 1 clinical study support the Company's decision to advance RDX013 to a Phase 2 clinical study in 2021.
Enhanced commercial capabilities and market readiness with hiring of market access, patient services, marketing, and sales leadership teams.
Strengthened leadership team with key appointments of Chief Commercial Officer, Susan Rodriguez, Chief Financial Officer, Justin Renz and Senior Vice President, Global Therapeutic Strategies and Patient Advocacy, Laura Williams.
In October 2020, launched "Can We Do Better?" Disease Awareness Campaign highlighting significant challenges in current management of hyperphosphatemia, new mechanistic understanding of phosphate absorption, and Ardelyx's commitment to advancing patient care.
In November 2020, hosted a virtual analyst day featuring German Hernandez, M.D., FASN, FACP, associate nephrologist at El Paso Kidney Specialists and clinical associate professor of medicine at Texas Tech University Health Sciences Center; Jennifer Robinson, president of Spherix Global Insights; and Douglas Paul, PharmD, Ph.D., vice president and partner at MME. The event focused on the company's proposed launch and commercialization plans in anticipation of the potential approval of tenapanor for the control of serum phosphorus in adult patients with CKD on dialysis. Additionally, the company reviewed its pipeline, including RDX013 for hyperkalemia and RDX020 for metabolic acidosis.
From November 2020 through February 2021, Ardelyx sold 8,198,217 shares of common stock under its At-the-Market Facility with Jefferies LLC for gross proceeds before commissions of $56.7 million, which includes approximately $21.7 million in gross proceeds in the fourth quarter 2020.
Full Year 2020 Financial Results
Cash Position: As of December 31, 2020, Ardelyx had total capital resources including cash and investments of $188.6 million compared to $247.5 million as of December 31, 2019.
Revenue and Cost of Revenue: Total revenues were $7.6 million for the year ended December 31, 2020 related to the company's ex-U.S. collaboration partnerships, and cost of revenues was $0.1 million related to payments due to AstraZeneca in accordance with the company's termination agreement entered into with AstraZeneca in June 2015 compared to total revenues of $5.3 million and cost of revenues of $0.6 million for the year ended December 31, 2019.
R&D Expenses: Research and development expenses were $65.1 million for the year ended December 31, 2020, a decrease of $6.6 million, or 9%, compared to $71.7 million for the year ended December 31, 2019. The decrease in R&D expenses was primarily related to the winding down of expenses associated with our Phase 3 clinical program for tenapanor for the control of hyperphosphatemia, partially offset by higher expenses attributable to research expenses associated with our research collaboration and option agreement entered into with KKC in 2019.
G&A Expenses: General and administrative expenses were $33.2 million for the year ended December 31, 2020, an increase of $8.9 million, or 37%, compared to $24.3 million for the year ended December 31, 2019. The increase was primarily due to an increase in costs associated with building and staffing our commercial infrastructure and teams as we prepare for the anticipated U.S. launch of tenapanor for the control of serum phosphorus in CKD patients on dialysis. The increase consisted of headcount and related personnel costs and an increase in external spending for disease awareness initiatives, commercial infrastructure and strategy.
Net Loss: Net loss for the year ended December 31, 2020, was $94.3 million compared to a net loss of $94.9 million for the year ended December 31, 2019.
Ardelyx expects that its cash, cash equivalents and investments will be sufficient to fund the company's operations into the second half of 2022 based on its current operating plans.
