MONTREAL, QUEBEC -- (Marketwired) -- 03/19/18 -- Knight Therapeutics Inc. (TSX: GUD) ("Knight") announced today a license agreement with Ardelyx, Inc. (NASDAQ: ARDX)("Ardelyx") that provides Knight with exclusive rights to commercialize tenapanor in Canada. Tenapanor is Ardelyx's oral, first-in-class small molecule treatment that has completed Phase 3 development for irritable bowel syndrome with constipation (IBS-C) and is being evaluated in a second Phase 3 study for hyperphosphatemia.
Under the terms of the agreement, Knight will pay up to CAD 25 million in total payments including an upfront payment and development and sales milestones, as well as double-digit tiered royalties on net sales. Knight will have the exclusive rights to market and sell tenapanor in Canada.
"We are excited to bring Canadian patients a product like tenapanor with its differentiated mechanism and established efficacy and safety profiles in both IBS-C and hyperphosphatemia," said Jonathan Ross Goodman, chief executive officer of Knight. "The addition of tenapanor to our pipeline will further enhance Knight's leadership in GI disorders. Because of its novel mechanism, we believe tenapanor will have advantages in treating IBS-C through an entirely new approach than those of today's approved medicines. In addition, we see great potential for tenapanor as the first and only new option outside of phosphate binders to treat hyperphosphatemia, with an opportunity to make an important difference for patients who would benefit from a new safe, effective and easy to take alternative. We look forward to working with the Ardelyx team and Health Canada to bring tenapanor to Canadian patients."
"Knight has a proven approach of successfully collaborating with biotechnology companies to bring forward important medicines, which makes them an invaluable component to our strategy of working with industry leaders to bring tenapanor to patients with IBS-C and hyperphosphatemia," said Mike Raab, president and chief executive officer of Ardelyx. " With a highly differentiated product profile, we believe that tenapanor will make a meaningful impact on Canadian patients and are pleased to be collaborating with the experienced and proven Knight team to make this a reality."

About Tenapanor
Tenapanor, discovered and developed by Ardelyx, is a first-in-class, proprietary, minimally absorbed, oral, experimental medication in late-stage clinical development. It has a unique mechanism of action that, in IBS-C, acts by inhibiting, or blocking, the NHE3 transporter in the gastrointestinal (GI) tract to reduce the absorption of dietary sodium, which leads to an increased amount of sodium within the gut. This increased sodium increases water in the gut, which loosens stool, helping to alleviate constipation. Preclinical studies have shown that tenapanor may work to reduce abdominal pain caused by IBS-C through the inhibition of TRPV-1 dependent signaling. Ardelyx has successfully completed its T3MPO program designed to support the registration of tenapanor for the treatment of IBS-C. Collectively, the T3MPO-1 and T3MPO-2 Phase 3 trials demonstrated that tenapanor had a durable effect on reducing constipation and abdominal pain caused by IBS-C, in many patients treated. The favorable safety profile of tenapanor is supported by the completed T3MPO-3 long-term, safety extension study. With the completion of this program, Ardelyx is preparing a New Drug Application for tenapanor for IBS-C, which the company intends to submit to the U.S. Food and Drug Administration in the second half of 2018.
Tenapanor is also in Phase 3 development for the treatment of hyperphosphatemia in patients with end-stage renal disease who are on dialysis. In hyperphosphatemia, tenapanor blocks the NHE3 sodium transporter in the GI tract, reducing the absorption of dietary sodium and resulting in increased protons within the cells. The increase in protons causes a reduction in phosphate uptake by tightening junctions or pores that regulate phosphate absorption in the GI tract. Overall, this mechanism appears to be preferential to phosphate absorption given that Ardelyx has not observed any meaningful changes in other ions, other than sodium, in preclinical or clinical studies. Ardelyx completed its first Phase 3 clinical trial for tenapanor in hyperphosphatemia, which demonstrated a statistically significant primary endpoint, the difference in change in serum phosphorus between the pooled tenapanor-treated patients and placebo-treated patients from the end of the eight-week treatment period to the end of the four-week randomized withdrawal period, in the responder population. Tenapanor was well-tolerated in the trial. Ardelyx has begun treating patients in a second Phase 3 clinical trial, the Phreedom Trial, with data anticipated in 2019.
