PURPOSE: This narrative review explores the currently published studies that have evaluated tenapanor for the treatment of hyperphosphatemia in end-stage kidney disease (ESKD) patients on hemodialysis. This medication's new phosphate lowering mechanism of action reduces intestinal phosphate absorption predominantly through reduction of passive paracellular phosphate flux by inhibition of the sodium/hydrogen exporter isoform 3 (NHE3). Tenapanor additionally prevents active transcellular phosphate absorption compensation by decreasing the expression of sodium phosphorus 2b transport protein (NaPi2b).
METHODS: A comprehensive search of the literature was conducted using PubMed and ClinicalTrials.gov search engines. The search term "tenapanor hyperphosphatemia" was used for study retrieval. Results were limited to studies published in the English language and excluded review articles. Human, animal, and in vitro studies were included. No date range was specified.
RESULTS: A total of 11 primary studies were identified and included in this review, the largest human study of which enrolled 236 patients. Each study is presented in table format along with measured end points.
CONCLUSIONS: Tenapanor is the first drug in its class that lowers hyperphosphatemia in ESKD patients through a novel mechanism of action involving paracellular inactive transport. Although more studies are needed, early results indicate that tenapanor may have a place in managing hyperphosphatemia in ESKD patients both as monotherapy and as an adjunct to existing phosphate binder therapy.
