Sirolimus (Rapamune®) for Autosomal Dominant Polycystic Kidney Disease (ADPKD)

February 26, 2014 updated by: University of Zurich

Sirolimus (Rapamune®) for Patients With Autosomal Dominant Polycystic Kidney Disease (ADPKD): a Randomized Controlled Study.

The aim of our study is to investigate whether Rapamune used at a low dose (2 mg/d) retards cyst growth and slows renal functional deterioration in patients with ADPKD.

Detailed Description

Currently there is no treatment for ADPKD other than supportive care and blood pressure control. Usually dialytic treatment or renal transplantation becomes necessary when the disease has progressed to end-stage renal failure.We and others could demonstrate that rapamycin, a classical mTOR inhibitor, retards cyst growth and preserves renal function in a rodent model of ADPKD. The aim of our study is to investigate whether Rapamune (2 mg/d) retards cyst growth and slows renal functional deterioration in patients with ADPKD. We anticipate that we can slow disease progression and delay the need for chronic renal replacement therapy by the inhibition of mTOR with Rapamune. This is a 24-month prospective, controlled, open label study with 2 parallel groups in patients with ADPKD. Patients will be randomized at a 1:1 ratio to one of the 2 treatment arms. Primary endpoint is percentage change of renal volume measured by high resolution magnetic resolution imaging.
