HealthCare Royalty Partners funding supports the ongoing launch of IBSRELA® in the United States in exchange for future hyperphosphatemia royalty payments from Ardelyx Japanese collaboration partner
WALTHAM, Mass., June 30, 2022 /PRNewswire/ -- Ardelyx, Inc. (Nasdaq: ARDX), a biopharmaceutical company founded with a mission to discover, develop and commercialize innovative first-in-class medicines that meet significant unmet medical needs, today announced that the company may receive up to $20 million from HealthCare Royalty Partners (HealthCare Royalty) from the sale of its future royalties and sales milestones from Kyowa Kirin Co., Ltd (Kyowa Kirin), its collaboration partner in Japan for the commercialization of tenapanor for hyperphosphatemia.
"We've been working with HealthCare Royalty for many years looking to find an opportunity for us to work together. They have been following the progress Kyowa Kirin has made in the development of tenapanor in Japan and this financing further validates the value and potential of tenapanor to treat patients with hyperphosphatemia," said Mike Raab, president and chief executive officer of Ardelyx. "Together with the development milestones that may become due under the license agreement with Kyowa Kirin and the payments that may become due to Ardelyx under the recent amendment to the license agreement with Kyowa Kirin, we now have the opportunity to receive up to $85 million in non-dilutive capital based on the potential of tenapanor for hyperphosphatemia in Japan."
Under the terms of the agreement, Ardelyx will receive from HealthCare Royalty a $10 million upfront payment, an additional $5 million following Kyowa Kirin's receipt of regulatory approval to market tenapanor for hyperphosphatemia in Japan, and $5 million in the event net sales in Japan exceed a certain target level by 2025. In return, HealthCare Royalty will receive the royalty payments and commercial sales milestones that Ardelyx may earn under the license agreement with Kyowa Kirin.
"There has been a dearth of innovation in the hyperphosphatemia market for too long and we believe tenapanor, as an innovative non-binder therapy, has the potential to address signficiant unmet needs in treating and controlling hyperphosphatemia," said Clarke Futch, chairman and chief executive officer of HealthCare Royalty. "We are pleased to support Ardelyx's efforts, with its partner Kyowa Kirin, in gaining potential approval and commercializing tenapanor for hyperphosphatemia in Japan."
On April 11, 2022, Ardelyx announced that it had amended its license agreement with Kyowa Kirin. Under the agreement, in consideration for a reduction in the royalty rate due to Ardelyx upon net sales in Japan, Kyowa Kirin agreed to pay Ardelyx consideration of up to $40 million payable in two tranches, with payment due following Kyowa Kirin's filing with the Japanese Ministry Health, Labour and Welfare (MHLW) of its application for marketing approval for tenapanor, which Kyowa Kirin has reported is expected in the second half of 2022, and the second payment due following Kyowa Kirin's approval to market tenapanor for hyperphosphatemia in Japan, which Kyowa Kirin has reported is currently expected in the second half of 2023.
The royalty rate at which Kyowa Kirin will make payments on net sales to Ardelyx under the amended license agreement was reduced from the high teens to low double digits for a two-year period, and then to mid-single digits. These royalty payments, along with certain sales milestones that may become due to Ardelyx under the license agreement have now been sold to HealthCare Royalty.
