Ardelyx Reports First Quarter 2020 Financial Results and Recent Business Highlights

FREMONT, Calif., May 7, 2020 /PRNewswire/ -- Ardelyx, Inc. (Nasdaq: ARDX), a specialized biopharmaceutical company focused on developing innovative first-in-class medicines to improve treatment for people with kidney and cardiovascular diseases, today reported business highlights and financial results for the first quarter ended March 31, 2020.

"During these unprecedented times, our priorities are focused on the well-being and safety of our employees, patients, and communities, while continuing on our mission to provide patients with first-in-class, disruptive medicines based on our breakthrough science," said Mike Raab, president and chief executive officer of Ardelyx. "We are fortunate that much of our clinical work has been completed, with minimal impact of the pandemic on our business, and we are on track to submit our NDA for tenapanor for the control of serum phosphorus in adult patients with CKD on dialysis by mid-year. In preparation for potential approval in mid-2021, we are laying the foundation for launch with important pre-commercial activities underway."

Recent Business and Pipeline Updates

• Initial data from NORMALIZE released in December 2019 demonstrated that of the 73 patients, treated for more than one month, 42% achieved normal phosphorus levels of less than 4.6 mg/dL and of those, 58% accomplished this with either tenapanor alone or with tenapanor in combination with only one to three sevelamer tablets per day. These early and exciting data represent a 45% improvement over current phosphate binder data from the 2019 Dialysis Outcomes and Practice Patterns Study (DOPPS), an ongoing, national prospective study of hemodialysis practice.
• Appointed industry veteran, Onaiza Cadoret-Manier to the company's board of directors.
• Our collaboration partner in Canada, Knight Therapeutics, received approval from Health Canada for IBSRELA® for the treatment of IBS-C in adults.
• Planned initiation of the OPTIMIZE clinical trial in 2020, a study to inform physicians on the integration of tenapanor into clinical practice.

Expected 2020 Milestones

• Preparing NDA Submission for Tenapanor for the Control of Serum Phosphorus in mid-2020: With strong data from its clinical program for tenapanor, Ardelyx is preparing a New Drug Application for tenapanor for the control of serum phosphorus in adult patients with CKD on dialysis, which the company currently intends to submit to the U.S. Food and Drug Administration in mid-2020.
• Reporting AMPLIFY and PHREEDOM Phase 3 results and NORMALIZE Phase 4 results at upcoming medical conferences. 

First Quarter 2020 Financial Results

• Cash Position: As of March 31, 2020, Ardelyx had total cash, cash equivalents and short-term investments of $223.2 million, as compared to total cash, cash equivalents and short-term investments of $247.5 million as of December 31, 2019.
• Revenue: The company generated $1.2 million in revenue, which primarily represents collaborative development revenue, for the quarter ended March 31, 2020.
• R&D Expenses: Research and development expenses were $15.8 million for the three months ended March 31, 2020, a decrease of $4.6 million, or 22.3 percent, compared to $20.4 million for the three months ended March 31, 2019. The decrease was due primarily to a decrease in external R&D expenses, with a $5.1 million decrease in tenapanor-related expenses, as well as a $0.8 million decrease in RDX013 program-related expenses, partially offset by $0.8 million of higher expenses attributable to research conducted under the Research Collaboration and Option Agreement entered into with Kyowa Kirin Co., Ltd., in November 2019 and general R&D expenses. Of the overall tenapanor-related decrease, approximately $4.1 million relates to lower clinical study costs and approximately $1.4 million relates to lower manufacturing expenses.
• G&A Expenses: General and administrative expenses were $7.1 million for the three months ended March 31, 2020, an increase of $2.0 million, or 39.5 percent, compared to $5.1 million for the three months ended March 31, 2019. The increase in general and administrative expenses was primarily due to an increase in headcount and related personnel costs, including stock-based compensation costs related to option vesting and performance-based restricted stock units, severance expenses related to the departure of the company's former chief financial officer in March 2020, and an increase in professional services.
• Net Loss: Net loss for the quarter ended March 31, 2020 was $22.4 million, as compared to $26.1 million for the quarter ended March 31, 2019.
