Autosomal Dominant Polycystic Kidney Disease Clinical Trial
Official title:
Implementation of Metformin theraPy to Ease Decline of Kidney Function in Polycystic Kidney Disease (IMPEDE-PKD): A Randomised Placebo-Controlled Trial
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 rate of kidney function decline, reducing morbidity and mortality and improving the quality of life for ADPKD patients.
Autosomal Dominant Polycystic Kidney Disease (ADPKD) affects 12.5 million people worldwide and is the 4th leading cause of kidney failure. Cyst growth begins in childhood, and over decades leads to painful kidneys, hypertension and chronic kidney disease. ADPKD patients also have a high prevalence of anxiety, depression and poor quality of life. Despite this enormous burden, there is a lack of evidence for therapies and affordable, effective treatment options. 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 randomised controlled trial to investigate the effect of metformin on ADPKD disease progression. The study will recruit a total of 1,174 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. ;
