NephureTM enzyme was evaluated vs. placebo in reduction of urinary oxalate associated with food oxalate
Gainesville, Fla. (April 18, 2019) – Results from Captozyme, Inc.’s post-market study of an innovative enzyme to support kidney health have been accepted for poster presentation on May 4 at the American Urological Association (AUA) Annual Meeting in Chicago.
Emily Quintero, a medical student at the University of Florida, will present the moderated poster presentation.
Title A Prospective, Double-Blind, Randomized, Placebo-Controlled, Cross-Over Study Utilizing Orally Administered Oxalate decarboxylase (OxDC) to Reduce Urinary Oxalate
Poster Number PD38-01
Location MCP: W181c
Date/Time Saturday, May 4, 3:30 p.m. to 3:40 p.m.
Presenter Emily Quintero
These findings can provide new options for individuals with Idiopathic Hyperoxaluria, a disorder characterized by increased urinary oxalate levels, which is often associated with excessive intake of dietary oxalate, decreased dietary calcium, or increased endogenous production1.
AUA guidelines recommend that clinicians counsel patients with calcium oxalate stones and relatively high urinary oxalate to limit oxalate-rich foods2 –  a tall order for many patients due to variable levels of oxalate in a wide variety of nutritious plant-based foods3. Now, this innovative new enzyme could provide a first-of-its-kind solution for improved patient compliance for those following dietary guidelines for  kidney stone management.
Captozyme’s poster presentation will include new positive results from a prospective, double-blind, randomized, placebo-controlled study, cross-over study in healthy volunteers.  
“We are delighted to be presenting our clinical results, which further confirm the efficacy and potency of our oxalate-reducing enzyme to reduce urinary oxalate originating from food,” Helena Cowley, chief executive officer of Captozyme, said. “We look forward generating high-quality development data for NephureTM and other enzymes in our company pipeline.”
