Two key clinical development programs accelerated, tenapanor in IBS-C and RDX022 in hyperkalemia

Conference Call and Webcast Today at 8:30 a.m. ET
FREMONT, Calif., November 12, 2015 /PRNewswire/ Ardelyx, Inc. (NASDAQ: ARDX), a clinical-stage biopharmaceutical company focused on
gastrointestinal and cardio-renal diseases, today announced financial results for the third quarter ended September 30, 2015. The Company also today announced that two clinical trials were initiated in October 2015: a Phase 3 clinical trial
evaluating tenapanor for the treatment of constipation-predominant irritable bowel syndrome (IBS-C) and a clinical study evaluating the pharmacodynamic activity of RDX022, a potassium binder for the treatment of hyperkalemia. Additionally, the
Company indicated that it plans to initiate a Phase 2b study to evaluate tenapanor in CKD patients with hyperphosphatemia on dialysis in December 2015. Results from this study are currently expected in the second half of 2016.
We have made a tremendous amount of progress in our key clinical programs over the last few months and are on pace to surpass our previously announced
timelines for tenapanor and RDX022, Mike Raab, President and CEO of Ardelyx remarked. We are pleased to announce that we commenced the first Phase 3 clinical study of tenapanor in IBS-C in October and we now expect to commence the second
Phase 3 clinical study in December, rather than in the first quarter of 2016. A pharmacodynamic study is also now underway to evaluate our novel potassium binder, RDX022. While we previously anticipated that we would obtain results in the first half
of 2016, due to the rapid progress of the study we can now confirm that we expect results in January 2016. We are pleased with the team s productivity and look forward to ending the year with several mid to late-stage programs advancing in the
Highlights from the Third Quarter 2015 and Recent Clinical and Corporate Developments
Third Quarter 2015 Financial Results
The net loss in the third quarter of 2015 was $18.1 million, or $0.70 per basic and diluted share, compared to a net income of zero or $0.00 per basic and
diluted share in the third quarter of 2014.
Total revenue is comprised of licensing revenue and collaborative development revenue, which were both
related to the Company s license agreement with AstraZeneca. Total revenues decreased to zero in the third quarter of 2015 from $7.6 million in the third quarter of 2014 because of the termination of the AstraZeneca agreement in June 2015.
Research and development expense in the third quarter of 2015 increased to $14.7 million from $5.7 million in the third quarter of 2014. The change was
primarily due the $7.3 million in expenses incurred for the clinical trial material from AstraZeneca as well as an increase of $1.7 million for clinical development activities associated with tenapanor and RDX022, and process development for RDX022.
General and administrative expense was $3.4 million in the third quarter of 2015 as compared to $1.8 million in the third quarter of 2014. The increase
was primarily due to an increase in personnel expense and professional service fees.
Cash and cash equivalents were $129.0 million as of
September 30, 2015 as compared to $107.3 million as of December 31, 2014. The increase in cash and cash equivalents compared to December 31, 2014 was primarily due to $74.3 million in net proceeds, after all costs, from the issuance
of common stock and warrants to purchase common stock offset by changes in working capital, cash paid for purchases of property and equipment, the $15 million up-front payment to AstraZeneca in connection with the termination agreement, and the $10
million payment to AstraZeneca for reimbursement of certain research and development expenses incurred by AstraZeneca under the collaboration agreement during 2015.
