Implementation of Metformin theraPy to Ease Decline of Kidney Function in Polycystic Kidney Disease (IMPEDE-PKD)

Multiple Locations

Overview

This study will investigate if a medication (metformin) widely used in the treatment of diabetes could be re-purposed for the treatment of patients with a diagnosis of early stage ADPKD to slow the growth of kidney cysts, thereby slowing the rate of kidney function decline, reducing morbidity and mortality and improving the quality of life for ADPKD patients.

To date, only one disease modifying therapy is licensed for use in ADPKD (tolvaptan), but it is limited by its restricted availability, side effects and high cost. Metformin, an inexpensive and familiar drug, has been shown in previous studies to target cyst-forming signals, thereby slowing the cyst growth rate. IMPEDE-PKD is an Australian-led global Phase III randomized controlled trial to investigate the effect of metformin on ADPKD disease progression. The study will recruit a total of 1,164 adult ADPKD patients from around the world (250 from Australia). The outcomes of this research will identify effective and targeted therapies for ADPKD that will slow kidney function decline, reduce the impact of the illness and likelihood of death, and improve the quality of life for ADPKD patients and families.

Enrolled participants will be randomized to either (1) intervention group receiving metformin extended release (XR) plus standard of care, or (2) placebo plus standard of care.

  • Have an eGFR equal to or greater than 45 mL/min/1.73m2 and <90 mL/min/1.73m2/li>
  • Do not have diabetes mellitus
  • Are not taking tolvaptan
